Description

Technical Field

[0001] This utility model relates to the field of file technology, and in particular to an electric reciprocating file. Background Technology

[0002] The surface of a file is decorated with many fine teeth and stripes, which are used for micro-processing of surfaces such as metal, wood, and leather. When using it, the user holds the handle and moves it back and forth along the surface of the object to grind it. The different force applied by the user's arm and the long-term heavy physical operation will result in low processing accuracy of the polished object and reduce the efficiency of grinding with a file, making it time-consuming and laborious.

[0003] Later, a pneumatic file machine appeared on the market, changing the past manual processing mode to pneumatic processing. However, because the pneumatic file machine needs to be used with an air compressor, it consumes a lot of electricity, is noisy, and is difficult to carry, which is not conducive to its widespread use.

[0026] Please see Figures 1 to 7 In this embodiment of the utility model, an electric reciprocating file includes a handle 18. One end of the handle 18 is fixedly connected to a mounting shell 10. A bottom cover 4 is mounted on the bottom side of the mounting shell 10. A motor 12, a servo motor, is fixedly connected to the inner top side wall of the mounting shell 10. The output shaft of the motor 12 is fixedly connected to a vertical shaft 8. A fixed disk 11 is fixedly connected to the middle of the vertical shaft 8. An eccentric disk 7 is fixedly connected to the bottom side of the fixed disk 11 at a position offset from the center. Figure 7 As shown, the vertical shaft 8, the fixed disk 11, and the eccentric disk 7 are integrally formed. The bottom end of the vertical shaft 8 is rotatably connected to the side wall of the bottom cover 4 through the bearing 9. A connecting sleeve rod 6 is sleeved on the outside of the eccentric disk 7. The connecting sleeve rod 6 consists of a straight rod and a ring at one end of the straight rod. The inner diameter of the ring is the same as the diameter of the eccentric disk 7. The eccentric disk 7 is located inside the ring. One end of the connecting sleeve rod 6 is rotatably connected to a connecting rod 13 through a rotating shaft 5. The connecting rod 13 penetrates the side wall of the mounting shell 10. One end of the connecting rod 13 is connected to a file head 1 through a snap-fit ​​fixing device.

[0027] The snap-fit ​​fixing device includes a mounting head 2. A positioning groove 17 is provided on the side wall of the mounting head 2. The shape of the positioning groove 17 is adapted to the shape of one end of the connecting rod 13. An insert rod 3 passes through the upper side of the mounting head 2. The bottom end of the insert rod 3 extends into the positioning groove 17. A slot 16 adapted to the shape of the bottom end of the insert rod 3 is provided on the side wall of one end of the connecting rod 13. A pull plate 14 is fixedly connected to the upper end of the insert rod 3. A spring 15 is sleeved on the insert rod 3. The two ends of the spring 15 are fixedly connected to the pull plate 14 and the side wall of the mounting head 2, respectively. When it is necessary to replace the file head 1, the pull plate 14 can be grasped to drive the insert rod 3 away from the slot 16 at the end of the connecting rod 13. The mounting head 2 and the file head 1 can then be removed from one end of the connecting rod 13. Then, one end of the connecting rod 13 is inserted into the positioning groove 17 of the new file head 1, and the bottom end of the insert rod 3 is inserted into the slot 16 under the action of the spring 15. The replacement of the file head 1 can be completed quickly and conveniently.

[0028] The working principle of this utility model is as follows:

[0029] When in use, the motor 12 can be started, which can drive the vertical shaft 8 to rotate. The rotation of the vertical shaft 8 can drive one end of the connecting sleeve rod 6 to make a circular motion around the vertical shaft 8 as the axis through the eccentric disk 7. At this time, the other end of the connecting sleeve rod 6 can drive the connecting rod 13 to reciprocate and extend. The reciprocating movement of the connecting rod 13 can drive the file head 1 to work back and forth to perform grinding operations, which is more time-saving and labor-saving.
