[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 , the utility model provides a technical solution:

[0020] An eccentric gear grinding tool comprises a base 1, a support column 2, an eccentric disc 3 and a positioning column 4. The above structure is directly cited from the prior art and will not be described in detail here.

[0021] A sliding block 5 is fixedly connected to the bottom of the positioning column 4, and the shape of the sliding block 5 is set to be T-shaped. A sliding groove 6 is provided on the top of the eccentric disc 3. The sliding block 5 is slidably connected to the inner wall of the sliding groove 6. A movable plate 7 is fixedly connected to one side of the sliding block 5. A through groove 8 is provided on the inner wall of the movable plate 7. The positioning column 4 is fixed to the eccentric disc 3 by a fastener, and the eccentric disc 3 is fixed to the base 1 by a positioning piece.

[0022] Specifically, Figure 2 As shown, the fastener includes a support plate 9, which is fixedly connected to one side of the eccentric disc 3. The top of the support plate 9 is rotatably connected to a threaded column 10, and the threaded column 10 is slidably connected to the inner wall of the through groove 8. The outer wall of the threaded column 10 is connected to an extrusion plate 11 through a thread. The movable plate 7 is arranged between the support plate 9 and the extrusion plate 11, and the bottom of the extrusion plate 11 is fixedly connected to a limiting plate 12. The number of the limiting plates 12 is set to two and the two limiting plates 12 are mirror-symmetrically arranged with the extrusion plate 11 as the center, and the limiting plate 12 is slidably connected to the inner wall of the support plate 9.

[0023] Specifically, Figure 2 As shown, a handle 13 is fixedly connected to the top of the threaded column 10 , and a worker can use the handle 13 to more conveniently rotate the threaded column 10 .

[0024] Specifically, Figure 3 As shown, a support block 14 is fixedly connected to the top of the base 1, and a clamping column 15 is slidably connected to the inner wall of the support block 14. The clamping column 15 is cylindrical, and a clamping groove 16 is formed on the outer wall of the eccentric disc 3. The clamping column 15 is adapted to the clamping groove 16.

[0025] Specifically, Figure 3 As shown, a circular block 17 is fixedly connected to one end of the clamping column 15 , a spring 18 is fixedly connected to one side of the circular block 17 , the spring 18 is sleeved on the outer wall of the clamping column 15 , and the spring 18 is fixedly connected to one side of the supporting block 14 .

[0026] In summary, when the processing jig provided in this embodiment is used to fix the eccentric gear, the staff first grasps the positioning column 4 to move it, and the positioning column 4 will move along the slide groove 6 on the eccentric disc 3 through the sliding block 5, and the sliding block 5 will drive the movable plate 7 to move. After the positioning column 4 reaches the specified position, the staff grasps the handle 13 to rotate the threaded column 10, and the threaded column 10 will move the squeezing plate 11 through the thread, and the squeezing plate 11 will cooperate with the support plate 9 to squeeze and fix the movable plate 7, so that the movable plate 7 cannot move, and the movable plate 7 cannot move. The positioning column 4 cannot move, so the staff The eccentric gear can be fixed on the positioning column 4, so that the device can fix eccentric gears of different specifications. When the eccentric gear is processed and ground, since some eccentric gears have protrusions on the sides, the staff needs to adjust the grinding position of the gear. The staff can pull the clamping column 15 out of the clamping groove 16 through the circular block 17, and then the staff can rotate the eccentric disc 3 to rotate the eccentric gear, thereby adjusting the grinding position of the eccentric gear. After adjusting to the specified position, the staff can loosen the circular block 17, and the spring 18 will push the clamping column 15 to insert into the clamping groove 16 to fix the eccentric disc 3.
