背景技术Background technique
电钻是日常作业过程中常用的一种电动加工工具，可分为手电钻、冲击钻、锤钻三种类型，其工作原理是电磁旋转式或电磁往复式小容量电动机的电机转子做磁场切割做功运转，通过传动机构驱动作业装置，带动齿轮加大钻头的动力，从而使钻头刮削物体表面，更好的洞穿物体。Electric drill is an electric processing tool commonly used in daily operations. It can be divided into three types: electric hand drill, impact drill, and hammer drill. Its working principle is that the motor rotor of an electromagnetic rotary or electromagnetic reciprocating small-capacity motor does magnetic field cutting Running, the operating device is driven by the transmission mechanism, and the gear is driven to increase the power of the drill bit, so that the drill bit scrapes the surface of the object and penetrates the object better.
目前，电钻在建筑与工业领域广泛适用于建筑梁、板、柱、墙等的加固，装修、墙安装、支架、栏杆、广告牌、空调室外机、导轨、卫星接收器电梯、钢结构厂房等安装作业中，也适用于医学、海洋钻探和日常生活等领域中。且预计，未来十至十五年中，世界电动工具销售额将按每年5％的速度增长。电动工具是一种“低值易耗品”，在欧美地区，电动工具不仅作为一种工具，而且被作为一种礼品，成为相互馈赠的礼物，因而电钻具有较大的市场发展潜力。At present, electric drills are widely used in construction and industrial fields for reinforcement of building beams, panels, columns, walls, etc., decoration, wall installation, brackets, railings, billboards, air-conditioning outdoor units, guide rails, satellite receiver elevators, steel structure workshops, etc. In installation operations, it is also applicable in fields such as medicine, marine drilling and daily life. And it is estimated that in the next ten to fifteen years, the sales of electric tools in the world will grow at a rate of 5% per year. Electric tools are a kind of "low-value consumables". In Europe and the United States, electric tools are not only used as a tool, but also as a gift, which becomes a gift for each other. Therefore, electric drills have great market development potential.
现有技术中的电钻还存在其他一些不足，如电钻钻头除了旋转运动很少有向前的进给运动，并且钻孔的深度只能通过目测经验来判断，要钻多个深度要求相同的孔时无法准确控制；而且现有电钻技术中钻头大多裸露在外，有一定的安全隐患，且当需要钻孔的对象为木质或石膏等材质时，会产生很多的扬尘，对施工者的健康也有一定的危害。The electric drill in the prior art also has some other deficiencies, such as the electric drill bit rarely has a forward feed motion except for the rotary motion, and the depth of the drilled hole can only be judged by visual experience, and the same hole is required to drill multiple depths It cannot be accurately controlled; and most of the drill bits in the existing electric drill technology are exposed, which has certain potential safety hazards, and when the object to be drilled is made of wood or gypsum, a lot of dust will be generated, which is also harmful to the health of the builders. harm.

One end of the telescopic main shaft is provided with a driving gear, and the other end is provided with a driving block for driving the telescopic shaft to rotate. The contact between the telescopic shaft driving block and the screw rod is provided with a The screw thread on the surface of the screw rod matches the screw thread, and one end of the telescopic shaft is pierced with a collet shaft, and a collet is provided on the collet shaft, and a drill bit is provided on the collet.
本发明的能够快速进给的安全电钻在使用时，电机变速箱启动，通过啮合的齿轮驱动伸缩主轴转动，伸缩主轴转动过程中带动伸缩轴同步转动，伸缩轴转动过程中带动钻头部同步转动，可以完成钻孔操作；同时在伸缩轴转动过程中，通过齿轮啮合使丝杆转动，丝杆转动过程中驱动伸缩轴驱动块移动，进而带动伸缩轴移动，因此在钻孔过程中，连接于伸缩轴上的钻头部能够不断自动往前移动，实现快速进给。When the fast-feed safety electric drill of the present invention is in use, the motor gearbox is started, and the telescopic main shaft is driven to rotate through the meshing gears. During the rotation of the telescopic main shaft, the telescopic shaft is driven to rotate synchronously. During the rotation of the telescopic shaft, the drill head is driven to rotate synchronously. The drilling operation can be completed; at the same time, during the rotation of the telescopic shaft, the screw rod is rotated through the gear engagement. During the rotation of the screw rod, the driving block of the telescopic shaft is driven to move, which in turn drives the telescopic shaft to move. The drill head on the shaft can continuously and automatically move forward to achieve rapid feed.
该功能使得在钻孔过程中，电钻本体可以不移动，只通过不断进给的钻头来进行钻孔，因此稳定性高，成孔质量好。This function makes the electric drill body not move during the drilling process, and only drills through the continuously feeding drill bit, so the stability is high and the hole quality is good.
作为优选，所述伸缩轴驱动块与丝杆接触处设有驱动腔，所述驱动腔中设有可移动的驱动滑块，所述驱动滑块面向丝杆的表面上设有螺纹，所述驱动滑块在移动过程中其上的螺纹与丝杆表面的螺纹匹配啮合或分离；所述伸缩轴驱动块设有用于分离所述驱动滑块与丝杆的扭簧；所述驱动滑块还与侧向顶杆接触，所述侧向顶杆可使所述驱动滑块在驱动腔中移动并使其上的螺纹与丝杆表面的螺纹匹配啮合。As a preference, a drive cavity is provided at the contact between the telescopic shaft drive block and the screw rod, a movable drive slider is provided in the drive cavity, and threads are provided on the surface of the drive slider facing the screw rod. During the movement of the driving slider, the threads on it are engaged with or separated from the threads on the surface of the screw; the telescopic shaft driving block is provided with a torsion spring for separating the driving slider from the screw; the driving slider also Contacting with the lateral ejector rod, the lateral ejector rod can make the driving slider move in the driving cavity and make the threads on it match and engage with the threads on the surface of the screw rod.
作为对本发明的进一步改进，以上结构实现了钻头进给过程的可控：不钻孔时的空转状态下，驱动滑块在扭簧作用下与丝杆分离，因此丝杆的转动不会将力传递给驱动滑块，因此伸缩轴驱动块不会移动，当需要钻孔时，使侧向顶杆顶向驱动滑块，使驱动滑块在驱动腔中克服扭簧的弹力的移动并与丝杆接触，此时驱动滑块上的螺纹与丝杆表面的螺纹匹配啮合，在丝杆转动过程中，带动驱动滑块进而带动伸缩轴驱动块移动，实现进给效果，完成钻孔操作，十分方便。As a further improvement to the present invention, the above structure realizes the controllability of the drill bit feeding process: in the idling state when not drilling, the drive slider is separated from the screw rod under the action of the torsion spring, so the rotation of the screw rod will not force It is transmitted to the drive slider, so the telescopic shaft drive block will not move. When drilling is required, the lateral ejector rod is pushed against the drive slider, so that the drive slider can overcome the elastic force of the torsion spring in the drive cavity and move with the wire. At this time, the thread on the driving slider matches and engages with the thread on the surface of the screw rod. During the rotation of the screw rod, the driving slider is driven to move the telescopic shaft driving block to realize the feeding effect and complete the drilling operation. convenient.

作为对本发明的进一步改进，以上结构实现了钻孔深度的控制与钻头的反向自动拔出：通过在滑槽中移动深度调节件并固定在不同的位置，可以实现不同钻孔深度的设置，设置完成后，钻孔过程中钻头不断向前移动，当达到设定的深度时，伸缩轴驱动块的边沿与深度调节件位于电钻内部的一端相抵，并继续带动深度调节件连同深度调节器向前移动一点距离，此时限位孔拨动开关，电机变速箱中的齿轮开始反转，丝杆及伸缩轴都开始反转，伸缩轴驱动块开始反向移动，将钻头逐渐移出钻孔。达到初始位置时伸缩轴驱动块顶住深度调节器上的凸起，并带动进给方向开关。As a further improvement to the present invention, the above structure realizes the control of the drilling depth and the reverse automatic extraction of the drill bit: by moving the depth adjustment member in the chute and fixing it at different positions, the setting of different drilling depths can be realized. After completion, the drill bit moves forward continuously during the drilling process. When the set depth is reached, the edge of the telescopic shaft drive block and the end of the depth adjustment part located inside the electric drill will continue to drive the depth adjustment part together with the depth adjuster forward. Move a little distance, at this time the limit hole toggle switch, the gear in the motor gearbox starts to reverse, the screw rod and the telescopic shaft start to reverse, the telescopic shaft drive block starts to move in the opposite direction, and the drill bit is gradually moved out of the drilling hole. When the initial position is reached, the telescopic shaft driving block bears against the protrusion on the depth adjuster and drives the feed direction switch.
该功能使得在钻孔介绍的拔出钻头过程中，电钻本体可以不移动，只通过不断缩回的钻头来实现，因此稳定性高，成孔质量好。This function makes it possible for the electric drill body not to move during the process of pulling out the drill bit during the drilling introduction, but to realize it only through the continuously retracting drill bit, so the stability is high and the hole-forming quality is good.
作为优选，所述钻头部包括设于钻头外周的钻头套，所述钻头套前端设有供钻头穿过的通孔，所述钻头套外还套设有滑套，所述滑套上设有推杆，所述推杆的一端顶住侧向顶杆，另一端用于顶住待加工面。Preferably, the drill head includes a drill sleeve arranged on the outer periphery of the drill bit, the front end of the drill sleeve is provided with a through hole for the drill bit to pass through, the drill sleeve is also covered with a sliding sleeve, and the sliding sleeve is provided with Push rod, one end of the push rod withstands the lateral push rod, and the other end is used to withstand the surface to be processed.
