DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Refer to Figures 1-3 , a centering device for PEEK gear processing, including a support 1. A chute is provided on the right side wall of the support 1. A slider 3 is slidably connected to the inner side wall of the chute for driving the centering shaft 2 to move. The upper end of the slider 3 is fixedly connected with a vertically arranged handle 4 for facilitating the user to push the slider 3 to move. An opening is provided at the inner top of the chute. The upper end of the handle 4 slidably penetrates through the opening. Fixing rings 6 are fixedly connected to both the left and right sides of the slider 3 for improving the firmness between the centering shaft 2 and the slider 3. The fixing rings 6 are fixedly sleeved on the centering shaft 2;

[0022] In this embodiment, a horizontally arranged centering shaft 2 is fixedly inserted on the right side of the slider 3 for centering the gear. The left end of the centering shaft 2 penetrates through the slider 3 and the support 1. The centering shaft 2 is slidably connected to the support 1. The other end of the centering shaft 2 penetrates through the chute. A spring 8 and a push plate 7 arranged in an 'n' shape are slidably sleeved on the centering shaft 2. The spring 8 is used to elastically support the slider 3, and the push plate 7 is used to push and support the spring 8. The left end of the spring 8 abuts against the slider 3, and the right end of the spring 8 penetrates through the chute and abuts against the push plate 7. A horizontally arranged connecting plate 9 is arranged at the upper end of the push plate 7 for driving the push plate 7 to move. The upper end of the push plate 7 slidably penetrates through the connecting plate 9 and is fixedly connected with a connecting block 15 for supporting the push plate 7. A pull ring 16 is fixedly connected to the upper end of the connecting block 15 for facilitating the user to pull the connecting block 15 upward. A second magnet is fixedly connected to the lower end of the connecting block 15, and a first magnet 17 attracted to the second magnet is fixedly connected to the upper end of the connecting plate 9 for magnetically positioning the connecting block 15;

[0023] In this embodiment, a horizontally arranged slot is provided on the right side of the support 1 and near its top position. The left end of the connecting plate 9 is slidably inserted into the slot. A plurality of arc-shaped grooves are provided on the inner top of the slot. A ball is rotatably connected to the inner side wall of the arc-shaped groove for reducing the resistance between the connecting plate 9 when it moves and the inner top of the slot. A part of the ball penetrates downward through the arc-shaped groove. A limiting block 10 is fixedly connected to the lower end of the connecting plate 9 for cooperating with the limiting groove to limit the moving stroke of the connecting plate 9 and prevent the connecting plate 9 from completely disengaging from the slot. A limiting groove corresponding to the limiting block 10 is provided at the inner bottom of the slot, and the lower end of the limiting block 10 slidably extends into the limiting groove;

[0024] In this embodiment, a lead screw 11 is inserted into the left end of the connecting plate 9 for driving the connecting plate 9 to move. The lead screw 11 is threadedly connected to the connecting plate 9. The end of the lead screw 11 away from the connecting plate 9 is rotatably connected to the inner side wall of the slot. A worm gear 12 is fixedly sleeved on the end of the lead screw 11 away from the connecting plate 9 for driving the lead screw 11 to rotate. A worm 13 meshing with the worm gear 12 is rotatably connected to the inner bottom of the slot for driving the worm gear 12 to rotate. The upper end of the worm 13 penetrates through the support 1 and is fixedly connected with a knob 14 for facilitating the user to rotate the worm 13. The worm 13 is rotatably connected to the support 1. The helix angle of the worm 13 is smaller than the friction angle between the worm gear 12 and the worm 13 for self-locking and anti-loosening.

[0025] In this embodiment, first, manually rotate the knob 14 to drive the worm 13 to rotate. Through the meshing of the worm 13 and the worm wheel 12, drive the lead screw 11 to rotate. The lead screw 11 drives the connecting plate 9 to move leftward through the action of thread meshing. When the connecting plate 9 moves leftward, it will drive the push plate 7 to compress the spring 8. Through the elasticity of the spring 8, push the slider 3 to move leftward. Drive the centering shaft 2 through the slider 3 to perform centering operation on the gear. Manually push the handle 4 to drive the slider 3 to move rightward, and then the centering shaft 2 can be driven by the slider 3 to move away from the gear; during maintenance and repair, hold the pull ring 16 and pull it upward. Drive the connecting block 15 and the push plate 7 to be pulled out and removed upward through the pull ring 16. The spring 8 loses the support and shielding of the push plate 7, which facilitates the user to remove the spring 8 for maintenance and repair.
