在例如制冷、动力、加工等领域中，在对两个管件例如金属薄壁管件进行插接时，需要会对其中一个管件的端部进行扩孔。此时，通常会使用所谓的扩孔器。In fields such as refrigeration, power, processing, etc., when two pipe fittings such as metal thin-walled pipe fittings are inserted, it is necessary to ream the end of one of the pipe fittings. In this case, a so-called reamer is usually used.
然而，虽然现有技术中已经有各种各样的扩孔器，但这些扩孔器普遍存在操作不便、费时费力等问题。However, although there are various reamers in the prior art, these reamers generally have problems such as inconvenient operation, time-consuming and labor-intensive problems.
因此，需要一种能够更加方便快捷地进行扩孔操作的扩孔器。Therefore, there is a need for a reamer capable of performing reaming operations more conveniently and quickly.
发明内容Contents of the invention
本发明的一个或多个实施方式的一个目的是提供一种能够方便快捷地进行扩孔操作的扩孔器。An object of one or more embodiments of the present invention is to provide a reamer capable of conveniently and quickly reaming operations.
为了实现上述目的中的一个或多个，根据本发明的一个方面，提供了一种扩孔器，包括：本体，所述本体包括具有通孔的通道部和用于接收管件保持构件的接收部；力传递部件，所述力传递部件能够在所述通道部的通孔中沿所述通道部的轴向方向运动并且所述力传递部件的至少一部分外周面上设置有螺纹；扩孔头，所述扩孔头与所述力传递部件连接以对管件进行扩孔操作；以及接合装置，所述接合装置构造成能够选择性地与所述力传递部件接合，当所述接合装置与所述力传递部件接合时，所述接合装置为所述力传递部件提供反作用力，当所述接合装置与所述力传递部件脱开时，所述力传递部件能够沿其轴向滑动。In order to achieve one or more of the above objects, according to an aspect of the present invention, there is provided a reamer comprising: a body including a passage portion having a through hole and a receiving portion for receiving a pipe holding member a force transmission part, the force transmission part can move along the axial direction of the passage part in the through hole of the passage part and at least a part of the outer peripheral surface of the force transmission part is provided with threads; a reaming head, The reaming head is connected to the force transmission part for reaming the pipe; and an engagement device configured to selectively engage with the force transmission part when the engagement device is in contact with the The engagement means provides a reaction force to the force transmission part when the force transmission part is engaged, and the force transmission part is able to slide in its axial direction when the engagement means is disengaged from the force transmission part.
根据本发明的一种或几种实施方式的扩孔器的优点在于：The advantages of the reamer according to one or several embodiments of the present invention are:
在根据本发明的一种实施方式中，扩孔器包括构造成能够选择性地与力传递部件接合的接合装置，当接合装置与力传递部件接合时，接合装置为力传递部件提供反作用力，当接合装置与力传递部件脱开时，力传递部件能够沿其轴向滑动。在扩孔操作中，当使用者向下压力传递部件时，可以将接合装置置于与力传递部件脱开的位置，从而与力传递部件相连的扩孔头能够迅速滑动到与管件的端部接触的操作位置。然后，可以将接合装置置于与力传递部件接合的位置，此时，当使用者旋转力传递部件时，由于接合装置能够为力传递部件提供反作用力，所以施加到力传递部件上的旋转运动转换为力传递部件以及扩孔头的轴向向下的旋转运动，从而使用者能够以较小的力对管件进行扩孔操作。当对管件进行完扩孔操作之后，使用者可以将接合装置置于与力传递部件脱开的位置，由此可以将力传递部件迅速移动到初始位置。由于力传递部件在扩孔头实施扩孔操作之前和之后能够迅速移动，所以大幅度节省了整个扩孔器操作所用的时间。In one embodiment according to the present invention, the reamer includes engagement means configured to selectively engage the force transmission component, the engagement means providing a reaction force to the force transmission component when the engagement means is engaged with the force transmission component, When the engagement device is disengaged from the force transmission part, the force transmission part can slide in its axial direction. During the reaming operation, when the user presses down on the transmission part, the engagement device can be placed in a disengaged position from the force transmission part, so that the reaming head connected to the force transmission part can slide quickly to the end of the pipe The operating position of the contact. The engagement means can then be placed into engagement with the force transmission part, at which point, when the user rotates the force transmission part, the rotational movement applied to the force transmission part will It is converted into the axial downward rotational movement of the force transmission part and the reaming head, so that the user can perform the reaming operation on the pipe with a small force. After the reaming operation has been performed on the pipe, the user can place the engagement device in a disengaged position from the force transmission part, so that the force transmission part can be quickly moved to the initial position. Since the force transmission part can move quickly before and after the reaming operation performed by the reaming head, the time taken for the operation of the reamer is greatly saved.
在根据本发明的一种实施方式中，接合装置可以包括接合件。力传递部件的外周面上设置有螺纹，接合件上设置有能够与力传递部件上的螺纹接合的螺纹并且接合件能够在接合位置和非接合位置之间运动。在扩孔操作中，当使用者向下压力传递部件时，由于力传递部件的螺纹和接合件的螺纹之间的相互作用所产生的径向分力，接合件被移动到非接合位置，从而与力传递部件相连的扩孔头能够迅速到达与管件的端部接触的操作位置。然后，使用者旋转力传递部件，此时由于接合件处于接合位置，所以施加到力传递部件上的旋转运动通过螺纹副转换为力传递部件以及扩孔头的轴向向下的旋转运动，从而使用者能够以较小的力对管件进行扩孔操作。当对管件进行完扩孔操作之后，使用者可以将接合件移动到非接合位置，由此可以将力传递部件迅速移动到初始位置。由于力传递部件在扩孔头实施扩孔操作之前和之后能够迅速移动，所以大幅度节省了整个扩孔器操作所用的时间。此外，由于力传递部件与接合件的螺纹配合能够起到力放大的作用，所以大大减小了使用者进行扩孔操作时所需的力，并且确保了管件扩孔端的质量。In one embodiment according to the invention, the engaging means may comprise an engaging element. Threads are provided on the outer peripheral surface of the force transmission component, threads that can be engaged with the threads on the force transmission component are provided on the engaging element, and the engaging element can move between an engaging position and a non-engaging position. During the reaming operation, when the user presses down on the transmission part, due to the radial force component generated by the interaction between the threads of the force transmission part and the threads of the joint part, the joint part is moved to the non-engagement position, thereby The reaming head connected to the force transmission part can quickly reach the operating position in contact with the end of the pipe. Then, the user rotates the force transmission part, at this time, since the joint is in the engaged position, the rotational motion applied to the force transmission part is converted by the thread pair into an axial downward rotational movement of the force transmission part and the reaming head, thereby The user can ream the pipe with less force. After finishing the hole reaming operation on the pipe, the user can move the joint part to the non-joint position, thereby quickly moving the force transmission part to the initial position. Since the force transmission part can move quickly before and after the reaming operation performed by the reaming head, the time taken for the operation of the reamer is greatly saved. In addition, since the threaded fit between the force transmission part and the joint member can amplify the force, the force required by the user for reaming operation is greatly reduced, and the quality of the reaming end of the pipe is ensured.
在根据本发明的一种实施方式中，接合件例如以可枢转的方式固定在扩孔器的本体上，因此能够更加方便地操作接合件。In one embodiment according to the present invention, for example, the joint is fixed on the body of the reamer in a pivotable manner, so that the joint can be operated more conveniently.
在根据本发明的一种实施方式中，扩孔器还包括将接合件朝向接合位置偏置的弹性构件，例如压缩弹簧、拉伸弹簧或扭转弹簧。因此，当向下压力传递部件时，螺纹副之间的作用力能够克服弹簧的偏置力而将接合件移动到非接合位置。而当旋转力传递部件时，弹性构件能够可靠地将接合件保持在接合位置。In one embodiment according to the present invention, the reamer further comprises an elastic member, such as a compression spring, tension spring or torsion spring, which biases the engagement member towards the engagement position. Thus, when the transmission member is pressed downwards, the force between the thread pairs can overcome the biasing force of the spring to move the engagement member to the non-engagement position. And when the force transmitting part is rotated, the elastic member can securely hold the engaging member in the engaging position.
在根据本发明的一种实施方式中，扩孔器本体的通道部中的通孔为光面孔，所以当力传递部件能够在该通孔中自由地轴向运动。In one embodiment according to the present invention, the through hole in the channel part of the reamer body is a smooth hole, so the force transmission component can freely move axially in the through hole.
在根据本发明的一种实施方式中，在通道部和力传递部件之间设置有弹性构件。从而当扩孔操作完成后，当使用者将接合件移动到非接合位置时，力传递部件能够在该弹性构件的弹性力的作用下自动回复到初始位置。In one embodiment according to the invention, an elastic member is arranged between the channel part and the force transmission part. Therefore, after the hole reaming operation is completed, when the user moves the engaging member to the non-engaging position, the force transmission part can automatically return to the original position under the action of the elastic force of the elastic member.
在根据本发明的一种实施方式中，力传递部件和接合件的螺纹都构造成梯形螺纹，因此二者之间的作用力的径向分力能够更容易地将接合件移动到非接合位置。In one embodiment according to the invention, both the force transmission part and the thread of the joint are configured as trapezoidal threads, so that the radial component of the force between the two can more easily move the joint to the non-engagement position .
在根据本发明的一种实施方式中，扩孔器进一步包括将快速锁紧扩孔条的锁紧机构。更具体地，锁紧机构包括由锁紧螺钉构成的第一锁紧装置，锁紧螺钉的一端包括平面部。因此，与现有技术的锁紧螺钉的一端为圆锥形部的情况相比，当旋转本发明实施方式的锁紧螺钉时，锁紧螺钉仅需旋转更少的圈数（或者仅需更少的轴向方向的行程）即可将扩孔条锁紧。In one embodiment according to the present invention, the reamer further includes a locking mechanism for quickly locking the reaming strip. More specifically, the locking mechanism includes a first locking device constituted by a locking screw, one end of which includes a planar portion. Therefore, compared with the case where one end of the locking screw of the prior art is a conical portion, when the locking screw of the embodiment of the present invention is rotated, the locking screw only needs to rotate fewer turns (or only fewer The stroke in the axial direction) can lock the reaming strip.
在根据本发明的一种实施方式中，扩孔条的与锁紧螺钉相对的侧面为平坦表面。与扩孔条的侧面形成有与现有技术的锁紧螺钉的圆锥形部相对应的圆锥形凹槽的情况相比，当锁紧本发明实施方式的锁紧螺钉和扩孔条时，锁紧螺钉被锁紧所需的时间或锁紧螺钉被锁紧所需旋转的圈数或行程被大大缩短，从而提高了扩孔器的操作效率。In one embodiment according to the present invention, the side of the reaming strip opposite to the locking screw is a flat surface. Compared with the case where the side of the reaming bar is formed with a conical groove corresponding to the conical portion of the locking screw in the prior art, when the locking screw and the reaming bar according to the embodiment of the present invention are locked, the lock The time required for the tightening screw to be locked or the number of turns or strokes required for the locking screw to be locked is greatly shortened, thereby improving the operating efficiency of the reamer.
在根据本发明的一种实施方式中，扩孔器的锁紧机构进一步包括由弹性加载的突出元件例如碰珠构成的第二锁紧装置。该第二锁紧装置优选地设置成与第一锁紧装置跨过扩孔条相对。因此，能够更加稳定地锁紧扩孔条。In one embodiment according to the invention, the locking mechanism of the reamer further comprises a second locking means constituted by a spring-loaded protruding element, such as a bumper. The second locking device is preferably arranged opposite the first locking device across the reaming bar. Therefore, the reaming strip can be locked more stably.
在根据本发明的一种实施方式中，锁紧螺钉的外周表面上形成有限位槽，扩孔器本体的接收部中设置有能够与该限位槽接合的限位销。当锁紧螺钉向外拧出到预定位置时，限位销与限位槽的一个端面接合从而限制锁紧螺钉的进一步向外运动。因此，能够有效地防止锁紧螺钉脱落或丢失。In one embodiment according to the present invention, a limiting groove is formed on the outer peripheral surface of the locking screw, and a limiting pin capable of engaging with the limiting groove is arranged in the receiving portion of the reamer body. When the locking screw is screwed out to a predetermined position, the limiting pin engages with one end surface of the limiting groove so as to limit further outward movement of the locking screw. Therefore, it is possible to effectively prevent the locking screw from coming off or being lost.

具体实施方式detailed description
下文的描述性质上仅是示例性的而不是试图限制本发明、应用及用途。应当理解，在这些附图中，相应的参考数字指示相似的或相应的部件及特征。The following description is merely exemplary in nature and is not intended to limit the invention, application and uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.
下面将参照图1至图8描述根据本发明实施方式的扩孔器的基本构造和操作方式。The basic configuration and operation of a reamer according to an embodiment of the present invention will be described below with reference to FIGS. 1 to 8 .
如图1-2所述，根据本发明实施方式的扩孔器1基本上包括本体10、力传递部件20和与力传递部件20连接的扩孔头24。扩孔器1的扩孔头24能够与扩孔条40配合以进行扩孔操作的扩孔条40。在此，扩孔条40是用于保持待扩孔管件的管件保持构件的一种示例。本领域技术人员应该理解，管件保持构件并不局限于此，而是可以形成为其他构造。As shown in FIGS. 1-2 , the reamer 1 according to the embodiment of the present invention basically includes a body 10 , a force transmission part 20 and a reaming head 24 connected with the force transmission part 20 . The reaming head 24 of the reamer 1 can cooperate with the reaming bar 40 to perform the reaming operation. Here, the reaming bar 40 is an example of a pipe holding member for holding a pipe to be reamed. It should be understood by those skilled in the art that the tube holding member is not limited thereto, but may be formed in other configurations.
本体10可以包括具有通孔13的通道部12和用于接收管件保持构件特别是扩孔条40的接收部14。更具体地，接收部14中形成有接收通道15，扩孔条40能够被接收在该接收通道15中并且能够在该接收通道15中滑动。The body 10 may include a channel portion 12 having a through hole 13 and a receiving portion 14 for receiving a pipe holding member, in particular a reaming strip 40 . More specifically, the receiving portion 14 is formed with a receiving channel 15 in which the reaming strip 40 can be received and slid.
力传递部件20能够在通道部12的通孔13中沿通道部12的轴向方向运动。力传递部件20的至少一部分外周面上设置有螺纹22。优选地，通道部12的通孔13为光面孔，从而允许设置有螺纹22的力传递部件20在其中自由运动。此处，光面孔的含义为该孔的内表面没有设置螺纹，并不限制孔的内表面是光滑的，相反根据扩孔器结构的实际构造，该通孔13中可以包括突起、台阶等构造。力传递部件20的与设置有螺纹22的一端相反的另一端上设置有手柄28以方便使用者的操作。The force transmission member 20 is movable in the through hole 13 of the channel part 12 in the axial direction of the channel part 12 . Threads 22 are provided on at least a portion of the outer peripheral surface of the force transmission member 20 . Preferably, the through hole 13 of the channel part 12 is a smooth hole, so as to allow the force transmission part 20 provided with the thread 22 to move freely therein. Here, the smooth hole means that the inner surface of the hole is not provided with threads, and does not limit the inner surface of the hole to be smooth. On the contrary, according to the actual structure of the reamer structure, the through hole 13 may include structures such as protrusions and steps. . A handle 28 is provided on the other end of the force transmission component 20 opposite to the end provided with the thread 22 to facilitate the user's operation.
如图7A、7B和7C所示，扩孔条40包括第一半部分40-1和第二半部分40-2。第一半部分40-1和第二半部分40-2共同限定有多个保持孔46。这些保持孔46具有不同的内径以对应于具有不同外径的管件。第一半部分40-1和第二半部分40-2能够打开（如图7C所示）以放入或取出对应的管件。在图中所示的示例中，第一半部分40-1和第二半部分40-2能够绕附图标记47所示的部分枢转以打开和闭合，但是本领域技术人员应该理解第一半部分40-1和第二半部分40-2可以设计成彼此独立并且能够完全分开的两个部件。在每个保持孔46的一端设置有锥面部分46-1。该锥面部分46-1限定了管件的端部要被扩孔形成的形状。As shown in Figures 7A, 7B and 7C, the reaming bar 40 includes a first half 40-1 and a second half 40-2. The first half 40 - 1 and the second half 40 - 2 collectively define a plurality of retention apertures 46 . These retaining holes 46 have different inner diameters to correspond to pipes with different outer diameters. The first half 40-1 and the second half 40-2 can be opened (as shown in FIG. 7C ) to put in or take out the corresponding tubing. In the example shown in the figures, the first half part 40-1 and the second half part 40-2 can pivot to open and close about the part indicated by the reference numeral 47, but those skilled in the art will understand that the first The half part 40-1 and the second half part 40-2 can be designed as two parts which are independent of each other and can be completely separated. At one end of each holding hole 46, a tapered portion 46-1 is provided. The tapered portion 46-1 defines the shape in which the end of the tube is to be reamed.
扩孔头24与力传递部件20可以例如经由进给杆26连接，从而力传递部件20的螺旋向下的旋转运动能够传递到扩孔头24上。此外，如图4所示，扩孔头24可以具有例如圆锥形的端部25。扩孔头24特别是端部25的轴向方向相对于力传递部件20的轴向方向呈预定夹角。扩孔头24的圆锥形的端部25能够与扩孔条40中的保持孔46以及保持孔46上的锥面部分46-1配合以对管件的端部进行扩孔操作。扩孔头24的构造不局限于图中所示，而是可以采用现有技术中给出的各种其他构造。例如，扩孔头24可以直接连接到力传递部件20上，可以采用其他连接构造连接到进给杆26。The reaming head 24 and the force transmission part 20 can be connected, for example, via a feed rod 26 , so that the helical downward rotational movement of the force transmission part 20 can be transmitted to the reaming head 24 . Furthermore, as shown in FIG. 4 , the reaming head 24 can have, for example, a conical end 25 . The axial direction of the reaming head 24 , especially the end portion 25 , forms a predetermined angle with respect to the axial direction of the force transmission component 20 . The conical end 25 of the reaming head 24 can cooperate with the retaining hole 46 in the reaming bar 40 and the tapered portion 46 - 1 on the retaining hole 46 to ream the end of the pipe. The configuration of the reaming head 24 is not limited to what is shown in the figure, but various other configurations given in the prior art can be adopted. For example, the reaming head 24 may be connected directly to the force transfer member 20, or may be connected to the feed rod 26 using other connection configurations.
根据本发明实施方式的扩孔器1进一步包括接合装置S，所述接合装置构造成能够选择性地与力传递部件20接合。当接合装置S与力传递部件接合时，接合装置为力传递部件提供反作用力，当接合装置与力传递部件脱开时，力传递部件能够沿其轴向滑动。The reamer 1 according to the embodiment of the present invention further comprises engagement means S configured to be selectively engageable with the force transmission member 20 . When the engagement device S is engaged with the force transmission part, the engagement device provides a reaction force for the force transmission part, and when the engagement device S is disengaged from the force transmission part, the force transmission part can slide along its axial direction.
根据一种示例，接合装置S可以包括接合件60。接合件60设置在本体10上并且包括与力传递部件20的螺纹22接合的螺纹62。特别是，接合件60可以设置在本体10的通道部12上。接合件60能够在接合位置（如图4所示）和非接合位置（如图5所示）之间运动。在所述接合位置，接合件60的螺纹62能够与力传递部件20的螺纹22接合，而在所述非接合位置，接合件60的螺纹62能够与力传递部件20的螺纹22脱开。优选地，力传递部件20的螺纹22和接合件60的螺纹62都构造成梯形螺纹，如图6所示。因此，当力传递部件20向下运动时，螺纹22和螺纹62之间能够产生径向分力以将接合件60移动到非接合位置。According to one example, the engaging means S may comprise an engaging element 60 . The engagement piece 60 is provided on the body 10 and includes a thread 62 that engages with the thread 22 of the force transmission part 20 . In particular, the engagement piece 60 may be provided on the channel portion 12 of the body 10 . Engagement member 60 is movable between an engaged position (shown in FIG. 4 ) and a non-engaged position (shown in FIG. 5 ). In the engaged position, the thread 62 of the engaging element 60 can be engaged with the thread 22 of the force transmission part 20 , whereas in the disengaged position, the thread 62 of the engaging element 60 can be disengaged from the thread 22 of the force transmitting part 20 . Preferably, both the thread 22 of the force transmission part 20 and the thread 62 of the engaging part 60 are configured as trapezoidal threads, as shown in FIG. 6 . Therefore, when the force transmitting member 20 moves downward, a radial force component can be generated between the thread 22 and the thread 62 to move the engagement member 60 to the non-engagement position.
进一步地，接合件60可以例如以可枢转的方式固定在通道部12上，例如经由枢轴66固定在通道部12的突出部17上。优选地，接合件60可以在其大致中部的位置固定在通道部12上。此时，接合件60的位于枢轴66的一侧的一端设置有螺纹62，而接合件60的位于枢轴66另一侧的一端可以作为供使用者操作的按压部。Further, the joint member 60 may be fixed on the channel part 12 in a pivotable manner, for example, fixed on the protruding part 17 of the channel part 12 via the pivot 66 . Preferably, the engaging member 60 can be fixed on the channel portion 12 at a substantially central position thereof. At this time, one end of the engaging member 60 on one side of the pivot 66 is provided with a thread 62 , and the end of the engaging member 60 on the other side of the pivot 66 can be used as a pressing portion for the user to operate.
进一步地，扩孔器1还包括将接合件60朝向接合位置偏置的弹性构件64。尽管图中示出弹性构件64为以压缩弹簧，但是本领域技术人员应该理解该弹性构件64也可以构造成位于接合件60的设置有螺纹62的一端的拉伸弹簧或者位于枢轴66上的扭转弹簧。Further, the reamer 1 also includes an elastic member 64 that biases the engaging piece 60 toward the engaging position. Although the elastic member 64 is shown as a compression spring, those skilled in the art should understand that the elastic member 64 can also be configured as a tension spring located at the end of the joint 60 provided with the thread 62 or a spring located on the pivot 66. torsion spring.
采用如上构造的接合件60，在没有外力作用在接合件60上时，接合件60在弹性构件64的弹性力的作用下处于接合位置以与力传递部件20上的螺纹22接合。当使用者按压力传递部件60的没有螺纹的另一端（下文中也称之为按压部）时，接合件60绕枢轴66转动从而接合件60的螺纹62与力传递部件20的螺纹22脱开。当使用者压下手柄28以使得力传递部件20向下运动时，力传递部件20的螺纹22与接合件60的螺纹62之间的作用力产生的径向分力将克服弹性构件64的偏置力而将接合件60移动到非接合位置以允许力传递部件向下运动。当使用者旋转手柄28以旋转力传递部件20时，接合件60在弹性构件64的作用下处于接合位置，从而力传递部件20的螺纹22与接合件60的螺纹62相互作用而将力传递部件20的旋转运动转换为力传递部件20的轴向向下的旋转运动，由此将使用者的操作力放大。With the engaging piece 60 configured as above, when no external force acts on the engaging piece 60 , the engaging piece 60 is in the engaged position by the elastic force of the elastic member 64 to engage with the screw thread 22 on the force transmission part 20 . When the user presses the other end of the force transmission part 60 without threads (hereinafter also referred to as the pressing part), the joint 60 rotates around the pivot 66 so that the threads 62 of the joint 60 disengage from the threads 22 of the force transmission part 20. open. When the user depresses the handle 28 to move the force transmission part 20 downward, the radial component force generated by the force between the thread 22 of the force transmission part 20 and the thread 62 of the joint 60 will overcome the deflection of the elastic member 64. Force is applied to move the engaging member 60 to the disengaged position to allow the force transmitting member to move downward. When the user rotates the handle 28 to rotate the force transmission part 20, the joint 60 is in the engaged position under the action of the elastic member 64, so that the thread 22 of the force transmission part 20 interacts with the thread 62 of the joint 60 to force the force transmission part The rotational movement of 20 is converted into the axial downward rotational movement of the force transmission part 20, thereby amplifying the operating force of the user.
尽管在图中所示的示例中，接合件60示出为受弹簧偏压的扳机构件，但是本领域技术人员可以理解，接合件可以设计成其他形式，例如可以设计为沿力传递部件20的径向方向运动的受弹簧偏压的活动构件使得在不受外力的情况下该活动构件与力传递部件接合而在受到外力的情况下与力传递部件脱开。此外，本领域技术人员应该理解，弹性构件64是可以被省略的。在这种情况下，可以在本体10上设置其他的保持部件以将接合件保持在接合位置和/或非接合位置或者采用手动的方式将接合件保持在接合位置和/或非接合位置。Although in the example shown in the figures, the engagement member 60 is shown as a spring-biased trigger member, those skilled in the art will understand that the engagement member may be designed in other forms, for example, may be designed as a spring-biased trigger member. A spring-biased movable member moving in a radial direction is such that the movable member engages the force transmission part without an external force and disengages the force transmission part when subjected to an external force. In addition, those skilled in the art should understand that the elastic member 64 can be omitted. In this case, other retaining components may be provided on the body 10 to maintain the engaging element in the engaged position and/or the disengaged position or manually maintain the engaging element in the engaged position and/or the disengaged position.
根据本发明实施方式的扩孔器1进一步包括设置在通道部12和力传递部件20之间的弹性构件16，例如压缩弹簧。弹性构件16能够沿背离扩孔条40的方向朝向力传递部件20施加弹性力。The reamer 1 according to the embodiment of the present invention further includes an elastic member 16 , such as a compression spring, disposed between the channel portion 12 and the force transmission part 20 . The elastic member 16 is capable of applying an elastic force toward the force transmission part 20 in a direction away from the reaming bar 40 .
尽管图中所示的示例示出了一个接合件60，但是本领域技术人员应该理解，扩孔器1可以包括多个接合件60。例如，在扩孔器1包括2个接合件60的情况下，这2个接合件60可以相对于力传递部件20的轴向方向对称地布置在通道部12上。当然，本领域技术人员还可以设想设置3个或4个的接合件60以增加接合件60的螺纹和力传递部件的螺纹之间的接合的可靠性。Although the example shown in the figures shows one engagement member 60 , those skilled in the art will appreciate that the reamer 1 may include a plurality of engagement members 60 . For example, in the case where the reamer 1 includes two engagement pieces 60 , the two engagement pieces 60 may be symmetrically arranged on the channel portion 12 with respect to the axial direction of the force transmission member 20 . Of course, those skilled in the art can also conceive of providing three or four engaging parts 60 to increase the reliability of engagement between the thread of the engaging part 60 and the thread of the force transmission component.
根据本发明实施方式的扩孔器1可进一步包括用于锁紧扩孔条40的锁紧机构30。The reamer 1 according to the embodiment of the present invention may further include a locking mechanism 30 for locking the reaming bar 40 .
锁紧机构30可以包括第一锁紧装置30A。第一锁紧装置30A可以包括延伸穿过接收部14的壁的锁紧螺钉32。锁紧螺钉32的第一端包括平面部33。在此，锁紧螺钉32可以为平头螺钉或者锁紧螺钉32的第一端可以为截头圆锥形。锁紧螺钉32的与第一端相反的第二端可以包括把手部34。锁紧螺钉32的轴向方向可以与扩孔条40的轴向方向大致垂直。The locking mechanism 30 may include a first locking device 30A. The first locking means 30A may comprise a locking screw 32 extending through the wall of the receiving portion 14 . The first end of the locking screw 32 includes a flat portion 33 . Here, the locking screw 32 may be a grub screw or the first end of the locking screw 32 may be frusto-conical. A second end opposite the first end of the locking screw 32 may include a handle portion 34 . The axial direction of the locking screw 32 may be substantially perpendicular to the axial direction of the reaming bar 40 .
相应地，如图7B所示，扩孔条40的与锁紧螺钉32相对的侧面42构造为平坦表面。Correspondingly, as shown in FIG. 7B , the side 42 of the reaming strip 40 opposite to the locking screw 32 is configured as a flat surface.
与现有技术的锁紧螺钉的端部为圆锥形部并且扩孔条的侧面形成有该圆锥形部相对应的圆锥形凹槽的情况相比，当锁紧和松开本发明实施方式的锁紧螺钉32和扩孔条40时，由于锁紧螺钉32的平面部33和扩孔条40的平坦侧面，锁紧和松开所需的时间或锁紧螺钉所需旋转的圈数或行程被大大缩短，从而提高了扩孔器的操作效率。Compared with the situation in the prior art that the end of the locking screw is a conical part and the side of the reaming bar is formed with a conical groove corresponding to the conical part, when locking and loosening the embodiment of the present invention When locking the screw 32 and the reaming bar 40, due to the flat surface portion 33 of the locking screw 32 and the flat side of the reaming bar 40, the time required for locking and loosening or the number of turns or strokes required for the locking screw is greatly shortened, thereby improving the operating efficiency of the reamer.
可替代地，扩孔条40的与锁紧螺钉32相对的侧面42中也可以形成有至少一个用于与锁紧螺钉32配合的凹部，所述凹部的位置可以与扩孔条40中的保持孔46的位置相对应。在这种情况下，由于锁紧螺钉32具有平面部33，与上述现有技术的具有圆锥形部的锁紧螺钉相比，也可以减小锁紧和松开所需的时间。Alternatively, at least one recess for cooperating with the locking screw 32 may also be formed in the side 42 of the reaming bar 40 opposite to the locking screw 32 , and the position of the recess may be maintained with that of the reaming bar 40 . The positions of the holes 46 correspond. In this case, also, since the locking screw 32 has the flat portion 33, the time required for locking and loosening can be reduced as compared with the aforementioned prior art locking screw having a conical portion.
根据本发明实施方式的锁紧机构30还可以包括第二锁紧装置30B。第二锁紧装置30B可以跨过扩孔条40与第一锁紧装置30A相对。也就是，第二锁紧装置30B与第一锁紧装置30A可以分别位于扩孔条40的两侧。如图8所示，第二锁紧装置30B可以包括弹性加载的突出元件38，所述突出元件38朝向接收部14的内侧突出。在此，弹性加载的突出元件38可以构造成例如包括一个突出部件和一个设置在该突出部件背侧的弹簧元件。优选地，第二锁紧装置38可以构造成本领域中公知的碰珠。相应地，扩孔条40的与突出元件38相对的侧面44可以包括至少一个用于与突出元件38配合的凹部45。凹部45的位置与扩孔条40中的保持孔46的位置相对应。The locking mechanism 30 according to the embodiment of the present invention may further include a second locking device 30B. The second locking device 30B may be opposite the first locking device 30A across the reaming bar 40 . That is, the second locking device 30B and the first locking device 30A can be respectively located on two sides of the reaming bar 40 . As shown in FIG. 8 , the second locking device 30B may comprise a spring-loaded protruding element 38 protruding towards the inside of the receiving portion 14 . In this case, the spring-loaded projecting element 38 can be configured, for example, to include a projecting part and a spring element arranged on the rear side of the projecting part. Preferably, the second locking device 38 can be configured as a bumper known in the art. Correspondingly, the side 44 of the reaming strip 40 opposite the protruding element 38 may include at least one recess 45 for cooperating with the protruding element 38 . The position of the recess 45 corresponds to the position of the holding hole 46 in the reaming bar 40 .
由于第一锁紧装置30A和第二锁紧装置30B分别设置在扩孔条40的两侧，所以能够更加稳定地锁紧扩孔条40。Since the first locking device 30A and the second locking device 30B are disposed on both sides of the reaming bar 40 respectively, the reaming bar 40 can be locked more stably.
此外，可以在锁紧螺钉32的外周表面上形成限位槽35，并且可以在接收部14中设置能够与限位槽35接合的限位销36。当锁紧螺钉32向外拧出到预定位置时，限位销36可以与限位槽35的一个端面接合从而限制锁紧螺钉32的进一步向外运动。因此，能够有效地防止锁紧螺钉32脱落或丢失。另一方面，当锁紧螺钉32向内拧入到预定位置时，限位销36可以与限位槽35的另一个端面接合从而限制锁紧螺钉32的进一步向内运动。因此，能够有效地防止向扩孔条40施加过度的力。Furthermore, a stopper groove 35 may be formed on the outer peripheral surface of the lock screw 32 , and a stopper pin 36 engageable with the stopper groove 35 may be provided in the receiving portion 14 . When the locking screw 32 is screwed out to a predetermined position, the limiting pin 36 can engage with an end surface of the limiting slot 35 to limit further outward movement of the locking screw 32 . Therefore, it is possible to effectively prevent the locking screw 32 from coming off or being lost. On the other hand, when the locking screw 32 is screwed inward to a predetermined position, the limiting pin 36 can engage with the other end surface of the limiting groove 35 to limit further inward movement of the locking screw 32 . Therefore, it is possible to effectively prevent excessive force from being applied to the reaming bar 40 .
根据本发明实施方式的扩孔器1的操作方式如下。The reamer 1 according to the embodiment of the present invention operates as follows.
首先打开扩孔条40以将管件50放入对应内径的保持孔46中并且使得管件50的端部与扩孔条40的上表面平齐。然后，关闭扩孔条40以将管件50牢固地保持在扩孔条40中。The reaming bar 40 is first opened to place the pipe 50 into the holding hole 46 of the corresponding inner diameter and make the end of the pipe 50 flush with the upper surface of the reaming bar 40 . Then, the reaming bar 40 is closed to hold the tubular member 50 securely in the reaming bar 40 .
将保持有管件50的扩孔条40插入扩孔器1的接收部14的接收通道15中并且将扩孔条40滑动到预定位置使得保持有管件50的保持孔46与扩孔头24对齐。此时，弹性加载的突出元件38将配合在扩孔条40一侧44上的凹部45中以实现扩孔条40的精确定位。旋转锁紧螺钉32直到锁紧螺钉32的平面部33抵靠扩孔条40的平坦侧面42为止。由此实现扩孔条40的锁紧。Insert the reaming bar 40 holding the pipe 50 into the receiving channel 15 of the receiving part 14 of the reamer 1 and slide the reaming bar 40 to a predetermined position so that the holding hole 46 holding the pipe 50 is aligned with the reaming head 24 . At this point, the spring-loaded protruding elements 38 will fit into the recesses 45 on one side 44 of the reaming strip 40 to achieve precise positioning of the reaming strip 40 . The locking screw 32 is rotated until the flat portion 33 of the locking screw 32 abuts against the flat side 42 of the reaming bar 40 . This achieves locking of the reaming strip 40 .
使用者压下手柄28以使得力传递部件20向下运动，此时力传递部件20的螺纹22与接合件60的螺纹62之间的作用力产生的径向分力克服弹性构件64的偏置力而将接合件60移动到非接合位置以允许力传递部件向下运动直到与力传递部件20相连的扩孔头24接触管件50的端部位置。然后，使用者旋转手柄28以旋转力传递部件20，此时接合件60在弹性构件64的作用下处于接合位置，从而由于力传递部件20的螺纹22与接合件60的螺纹62相互作用，力传递部件20的旋转运动转换为轴向向下的旋转运动，该轴向向下的旋转运动进一步传递到扩孔头24使得扩孔头24抵靠扩孔条40中的保持孔46的锥面部分46-1对管件50进行滚压以实现扩孔操作。The user depresses the handle 28 so that the force transmission part 20 moves downward, at this time, the radial component force generated by the force between the thread 22 of the force transmission part 20 and the thread 62 of the joint 60 overcomes the bias of the elastic member 64 The force moves the engagement member 60 to the non-engagement position to allow the force transfer member to move downward until the reaming head 24 connected to the force transfer member 20 contacts the end position of the tubular member 50 . Then, the user rotates the handle 28 to rotate the force transmission part 20, and at this time the joint 60 is in the engaged position under the action of the elastic member 64, so that due to the interaction between the threads 22 of the force transmission part 20 and the threads 62 of the joint 60, the force The rotational movement of the transmission member 20 is converted into an axial downward rotational movement, which is further transmitted to the reaming head 24 so that the reaming head 24 abuts against the tapered surface of the holding hole 46 in the reaming bar 40 Section 46-1 rolls tubing 50 to effect the reaming operation.
当对管件50的扩孔操作完成后，如图5所示，使用者可以按压接合件60的按压部以将接合件60移动到非接合位置。此时，力传递部件20在弹性构件16的弹性力的作用下将自动向上运动而返回到初始位置。此后，使用者可以松开接合件60以使其自动返回到接合位置。After the reaming operation on the pipe member 50 is completed, as shown in FIG. 5 , the user can press the pressing portion of the engaging member 60 to move the engaging member 60 to the non-engaging position. At this time, the force transmission part 20 will automatically move upwards and return to the initial position under the action of the elastic force of the elastic member 16 . Thereafter, the user can release the engagement member 60 to automatically return to the engaged position.
然后，使用者旋转把手部34从而松开锁紧螺钉32。此后，可以取出并打开扩孔条40以取出完成扩孔的管件50。由此，完成了对管件50的扩孔操作。Then, the user rotates the handle portion 34 to loosen the locking screw 32 . Thereafter, the reaming bar 40 can be taken out and opened to take out the reamed pipe 50 . Thus, the reaming operation of the pipe member 50 is completed.
如上所述，在根据本发明实施方式的扩孔器中，由于接合件能够在接合位置和非接合位置之间移动，所以在扩孔头实施扩孔操作之前和之后力传递部件能够迅速地移动，从而大大减小了扩孔器实施扩孔操作所需的整体时间。另一方面，由于锁紧螺钉的端部具有平面部，所以可以减小锁紧或松开扩孔条所需的时间，从而进一步减小扩孔器实施扩孔操作所需的整体时间。此外，由于接合件和力传递部件之间的螺纹配合具有力的放大功能，使用者仅需要较小的力就能够实施扩孔操作，从而减小了使用者的操作负担。综上所述，根据本发明实施方式的扩孔器能够方便快捷省时省力地进行扩孔操作。As described above, in the reamer according to the embodiment of the present invention, since the engaging member can move between the engaging position and the non-engaging position, the force transmission member can move quickly before and after the reaming head performs the reaming operation. , thereby greatly reducing the overall time required for the reamer to implement the reaming operation. On the other hand, since the end of the locking screw has a flat portion, the time required for locking or loosening the reaming strip can be reduced, thereby further reducing the overall time required for the reamer to carry out the reaming operation. In addition, since the threaded fit between the joint member and the force transmission component has the function of amplifying the force, the user only needs a small force to implement the hole reaming operation, thereby reducing the user's operational burden. To sum up, the hole reamer according to the embodiment of the present invention can perform the hole reaming operation conveniently, quickly, time-saving and labor-saving.
