技术领域 Technical field
[0001] 本发明涉及紧固领域,具体是一种新型螺纹及加工方法。 [0001] The present invention relates to the field of fastening, and in particular to a novel thread and a method of processing.
背景技术 Background technique
[0002] 很多领域需要使用紧固件， 从机械， 电子， 到农业， 航空等都离不幵紧固件， 紧固件在使用过程中， 由于震动等原因会产生松动， 影响使用效果以致紧固失 效， 甚至造成严重事故， 因此多少年来人们一直在想尽办法设计更加坚固可靠 的紧固件， 紧固件主要由螺纹构成， 因此需要更加安全可靠的螺纹。 [0002] Many fields require the use of fasteners, from machinery, electronics, to agriculture, aviation, etc., fasteners, fasteners in the process of use, due to vibration and other reasons will cause loose, affecting the use of results to tighten Solid failure, and even serious accidents, so for many years people have been trying to design more robust and reliable fasteners, the fasteners are mainly composed of threads, so more safe and reliable thread is needed.
技术问题 technical problem
[0003] 本发明的目的是在于提供一种新型螺纹及装置， 具体是在螺纹的侧面有台阶的 螺纹， 可以防止紧固件发生松动， 以及设有该新型螺纹的螺栓螺钉等， 同吋提 供了加工方法。 [0003] The object of the present invention is to provide a new type of thread and device, specifically a stepped thread on the side of the thread, which can prevent the fastener from loosening, and the bolt screw provided with the new thread, etc. The processing method.
[0004] 本发明为实现上述目的， 通过以下技术方案实现： 一种新型螺纹， 在螺纹的侧 面有台阶， 其台阶在螺纹紧固的受力面， 其台阶由螺纹根部向螺纹顶部展幵， 台阶呈倒齿状， 其台阶在螺纹根部和螺纹顶部之间全部或部分， 相互配对使用 的螺纹都设所述的防松螺纹。 [0004] In order to achieve the above object, the present invention is achieved by the following technical solutions: A new type of thread has a step on the side of the thread, and the step is on the force receiving surface of the thread fastening, and the step is extended from the root of the thread to the top of the thread. The step is in the shape of an inverted tooth, and the step is all or part between the root of the thread and the top of the thread, and the threads used for pairing each other are provided with the locking thread.
[0005] 螺纹可以理解为是沿着直角三角形的一个直角边为轴转动， 直角三角形的斜边 卷绕在圆柱体上形成的， 三角形的斜边是光滑的， 卷绕出来的螺纹也是光滑的 ， 三角形的斜边如果是台阶状， 卷绕出来的螺纹也是台阶状， 光滑的斜面容易 打滑， 有台阶的斜面不容易打滑， 就像有台阶的盘旋的楼梯相比于没有台阶的 盘旋滑梯一个道理， 因此在螺纹的侧面设置台阶可以防止螺纹打滑， 进而起到 防止松动的作用； 螺纹在紧固件的具体使用中， 一般主要只有一个方向承受压 力， 此压力由被紧固的物件作用在紧固件上产生， 比如有外螺纹的螺栓和内螺 纹的螺帽， 在紧固后螺栓的螺纹受力的一面是与螺帽接触朝向被紧固物件的一 面， 而螺帽的螺纹受力的一面是与螺栓的螺纹接触背向被紧固件的一面， 两者 方向相反， 互为反作用力， 在这样两个互为反作用力的面上设置台阶， 可以增 加其互相的摩擦力， 防止松动， 紧固的过程是螺纹间先松动后紧配， 在紧配的 吋候螺纹间因为弹性形变而越过台阶顶部， 而因为弹性形变卡紧在台阶底部， 所以这种螺纹适合配合相同的螺纹互相啮合使用， 如设置在两个相互作用力接 触的位置， 更能发挥出这种螺纹的作用； 台阶的设置一般从螺纹的根部向螺纹 顶部展幵， 即以螺纹环绕的轴的径向向外展幵， 以直线展幵或渐幵线展幵， 为 了使螺纹能够有更好的防止松动的效果， 设置螺纹台阶为倒齿状， 即台阶具有 一个面与螺纹面倾斜为锐角， 具有另一个面垂直于螺纹面或稍微倾斜， 台阶之 间互相连接或者空余一定距离， 而在配套使用的螺纹也设置倒齿台阶， 两者倒 齿方向相反， 互相啮合， 这样如果在配套的螺栓和螺帽上设置这种螺纹， 当螺 栓和螺帽紧固后， 螺栓和螺帽之间的螺纹被压紧， 螺纹上的台阶因为压力不同 而互相啮合， 阻止两者之间滑动倒退； 因为有的螺纹的顶部比较薄， 如横截面 为三角形螺纹， 可以仅设置台阶在从螺纹根部到顶部间的一部分， 只设置在一 部分的吋候台阶高于螺纹表面， 如三角形螺纹仅设置在靠近螺纹根部的一段； 本发明的新型螺纹具有台阶， 因为螺纹都是呈螺旋状环绕， 因此台阶可设置成 靠近螺纹底部尺寸小， 靠近螺纹顶部尺寸大， 也可以从螺纹根部到顶部一个尺 寸。[0005] A thread can be understood as being rotated along a right-angled side of a right-angled triangle. The oblique side of a right-angled triangle is wound around a cylinder. The oblique side of the triangle is smooth, and the wound thread is also smooth. If the oblique side of the triangle is stepped, the thread that is wound is also stepped, the smooth slope is easy to slip, and the stepped slope is not easy to slip, just like a stepped spiral staircase compared to a stepped spiral slide Therefore, the step on the side of the thread can prevent the thread from slipping, thereby preventing the loosening. In the specific use of the fastener, the thread is generally only subjected to pressure in one direction, and the pressure is applied by the fastened object. Produced on the fastener, such as an externally threaded bolt and an internally threaded nut. After tightening, the threaded side of the bolt is in contact with the nut toward the side of the fastened object, and the nut of the nut is stressed. One side is in contact with the thread of the bolt facing away from the side of the fastener, the opposite direction of the two, the mutual reaction force, in such two mutual Surface reaction step is provided, can be increased Adding friction to each other to prevent loosening. The tightening process is that the threads are loosened and then tightly fitted. The tightly-matched threads are elastically deformed over the top of the step, and since the elastic deformation is clamped at the bottom of the step, The thread is suitable for intermeshing with the same thread, for example, it is disposed at the position where the two interacting forces are in contact, and the function of the thread can be exerted; the step is generally arranged from the root of the thread to the top of the thread, that is, The shaft surrounded by the thread is radially outwardly stretched, and is stretched or straightened in a straight line. In order to make the thread have a better anti-loose effect, the threaded step is inverted, that is, the step has a face and The thread surface is inclined at an acute angle, and the other surface is perpendicular to the thread surface or slightly inclined. The steps are connected to each other or are separated by a certain distance, and the thread used in the matching is also provided with an inverted tooth step, and the opposite directions of the two teeth are opposite to each other. Thus, if such a thread is provided on the matching bolt and nut, when the bolt and the nut are tightened, the thread between the bolt and the nut is Tight, the steps on the thread mesh with each other due to different pressures, preventing the slide between them from going backwards; because the top of some threads is thin, such as a triangular thread in cross section, only a part of the step from the root to the top of the thread can be set. , only a part of the waiting step is higher than the thread surface, such as the triangular thread is only disposed near a section of the thread root; the new thread of the invention has a step, because the thread is spirally surrounded, so the step can be set close to the thread The bottom is small in size and large in size near the top of the thread, and can also be one size from the root to the top of the thread.
[0006] 利用同样的原理而设置的螺纹， 可以是外螺纹或内螺纹， 可以应用在自攻螺钉 ， 其螺纹从螺纹根部到螺纹顶部侧面至少一个侧面设有台阶， 台阶为倒齿状， 这样在自攻螺钉被外力作用进入被钻入件后， 由于被钻入件的弹性形变而卡住 自攻螺钉螺纹的倒齿， 使其无法倒转。 [0006] The thread provided by the same principle may be an external thread or an internal thread, and may be applied to a self-tapping screw whose thread is provided with a step from at least one side of the thread root to the top side of the thread, and the step is inverted. After the self-tapping screw is applied by the external force into the drilled part, the inverted teeth of the self-tapping screw thread are caught due to the elastic deformation of the drilled part, so that it cannot be reversed.
[0007] 一种螺栓副， 包括螺栓和螺母， 螺栓设外螺纹， 螺母设内螺纹， 两者配台使用 ， 螺栓和螺母的螺纹在紧固受力的侧面都设有台阶， 台阶为倒齿状， 两者的台 阶方向相反互为啮合状， 台阶覆盖螺栓和螺母受力的侧面， 螺母紧固一面设法 兰， 法兰紧固面设台阶， 台阶为倒齿状， 在螺帽设置法兰， 紧固的吋候法兰靠 近被紧固件， 通过这样设置使各部分连接更加紧固， 防止松动。 [0007] A bolt pair includes a bolt and a nut, the bolt is provided with an external thread, and the nut is provided with an internal thread, and the two are used with a table. The thread of the bolt and the nut is provided with a step on the side of the fastening force, and the step is a reverse tooth. In the shape, the steps of the two are opposite to each other, the step covers the side of the bolt and the nut, the nut is fastened with a flange, the flange is fastened with a step, the step is inverted, and the flange is flanged. The fastening weathering flange is close to the fastener, and by this arrangement, the connection of each part is further tightened to prevent loosening.
[0008] 本发明可以在被紧固件上固定设置与紧固件接触面对应的台阶， 被紧固件和紧 固件都设有台阶， 两者的台阶互相啮合， 被紧固件的台阶采用焊接或铸造的方 法与被紧固件一体。 [0009] 本发明还提供多个加工制作方法， 由于本发明螺纹的台阶设置在螺纹的侧面， 不能用现有的滚压方法加工， 对于尺寸细小的螺纹可以采用激光或超声波等加 工， 设置多个激光装置同吋加工可以提高效率， 对于大型螺纹可以采用机械切 削或在螺纹侧面滚压等方法加工； 比如先预制好螺纹， 以冲压的方式在螺纹上 冲压出台阶， 每冲压一次后转动一个角度继续冲压， 可以同吋在螺纹的周围布 置多个冲压装置， 不仅在一个螺纹圆周内设置冲压装置， 还可沿着螺纹多个圆 周多层面设置， 进一步提高工作效率， 同样的方法可以使用切削， 设置多个切 削装置在螺纹周围， 提高效率， 另一种加工制作方法是可以用伞齿滚刀沿着螺 纹侧面滚动， 在螺纹表面滚压出台阶， 同吋设多个滚刀同吋使用以提高效率， 伞齿滚刀可以另外设置伞状滑轮， 伞齿滚刀和伞状滑轮固定在底座杆上， 伞齿 滚刀和伞状滑轮间有空隙， 螺纹插入空隙， 伞状滑轮限制螺纹， 伞状滑轮和伞 齿滚刀夹住螺纹并环绕螺纹转动， 在螺纹表面加工出台阶， 根据螺纹环绕直径 大小调整使用不同锥度滚刀， 根据螺纹厚度调整伞齿滚刀和伞状滑轮间距离， 本方法和装置既可以加工外螺纹也可以加工内螺纹。[0008] The present invention can be fixed on the fastener corresponding to the step of the fastener contact surface, the fastener and the fastener are provided with a step, the steps of the two mesh with each other, by the fastener The steps are welded or cast together with the fasteners. [0009] The present invention also provides a plurality of processing and manufacturing methods. Since the step of the thread of the present invention is disposed on the side of the thread, it cannot be processed by the existing rolling method, and the thread having a small size can be processed by laser or ultrasonic, and the setting is large. The same laser processing can improve the efficiency. For large threads, it can be machined or rolled on the side of the thread. For example, the thread is prefabricated, the step is punched on the thread, and one is rotated after each punch. The angle continues to be stamped, and multiple punching devices can be arranged around the thread, not only in the circumference of one thread, but also in the multiple layers of the circumference of the thread to further improve the working efficiency. The same method can be used for cutting. , a plurality of cutting devices are arranged around the threads to improve the efficiency, and another processing method can be used to roll along the side of the thread with a bevel tooth hob, roll the step on the thread surface, and use a plurality of hobs simultaneously. In order to improve efficiency, the bevel gear hob can be additionally provided with an umbrella pulley, And the umbrella pulley is fixed on the base rod, there is a gap between the bevel tooth hob and the umbrella pulley, the thread is inserted into the gap, the umbrella pulley limits the thread, the umbrella pulley and the bevel tooth hob clamp the thread and rotate around the thread, in the thread The surface is machined with steps, and different taper hobs are used according to the diameter of the thread. The distance between the bevel hob and the umbrella pulley is adjusted according to the thickness of the thread. The method and the device can process the external thread or the internal thread.
[0010] 本发明的新型螺纹还可以采用铸造的方法制作， 其一方法是在一个模具内设置 多个产品单元， 一次成型多个产品， 其二方法是采用铸造后分割加工的方法， 即先铸造出一个长度为多个含有本发明螺纹产品长度的的半成品， 然后分割再 加工修整成型， 例如加工含有本发明螺纹的螺栓， 先铸造出一根含有本发明螺 纹的长螺杆， 分割螺杆后加工螺栓头而成， 铸造的吋候可以在长螺杆上还有多 个螺栓头， 螺栓头连接另一个螺栓尾， 铸造后分割成型， 而加工含有本发明螺 纹的螺帽， 也可先铸造出一根含有本发明内螺纹的长筒， 后分割整形而成， 因 为此方法是铸造成型可以用于凹陷或凸出螺纹表面的台阶， 本方法也可以应用 于加工其他类似装置。 [0010] The novel thread of the present invention can also be produced by a casting method, one method is to set a plurality of product units in one mold, and to form a plurality of products at one time, and the second method is to adopt a method of splitting and processing after casting, that is, first Casting a semi-finished product having a length of a plurality of threaded products of the present invention, and then dividing and refinishing, for example, processing a bolt containing the thread of the present invention, first casting a long screw containing the thread of the present invention, and dividing the screw into a post-processing The bolt head is formed. When casting, there may be a plurality of bolt heads on the long screw. The bolt head is connected to the other bolt tail, and is divided and formed after casting. The nut containing the thread of the present invention can also be cast first. The long tube containing the internal thread of the present invention is formed by post-segmentation, because the method is a step which can be used for casting to dent or protrude the surface of the thread, and the method can also be applied to processing other similar devices.
[0011] 上述各个加工方法也适用于其他螺纹加工， 可以与现有机械加工装置组合在一 起使用。 [0011] Each of the above processing methods is also applicable to other threading processes and can be used in combination with existing machining equipment.
[0012] 上述的台阶的面可以是平面， 可以是弧形面。 [0012] The face of the step described above may be a flat surface and may be a curved surface.
