A motor 11 is connected to the fixed block 3, and a gear groove 10 is provided inside the fixed block 3. The inside of the gear groove 10 is connected to the inside of the transmission groove 6. A large gear 7 is provided inside the gear groove 10. The output end of the motor 11 is fixedly connected to the top of the large gear 7 through a coupling. The surface of the large gear 7 is connected to the surface of the gear ring 8 through tooth meshing. The rotation of the large gear 7 drives the rotation of the gear ring 8. The gear ring 8 drives the transmission gear 9 to make circular motion inside the transmission groove 6 under the constraint of the teeth on the inner wall of the transmission groove 6. The bottom of the transmission gear 9 is rotatably connected to the transmission rod 12. The transmission rod 12 is L-shaped. A sliding groove 13 is provided inside the machining frame 2. The inside of the sliding groove 13 is connected to the inside of the transmission groove 6. The inside of the sliding groove 13 is slidably connected to the surface of the transmission rod 12. The top of the transmission rod 12 is fixedly connected to the inclined plate 15. One side of the inclined plate 15 is rotatably connected to the inside of the machining frame 2. The bottom of the transmission rod 12 is fixedly connected to the cleaning block 14, which can clean the metal debris inside the machining frame 2.

[0024] A square block 20 is fixed inside the processing frame 2. The square block 20 has a threaded groove 16 extending to the outside. A bidirectional threaded rod 17 is rotatably connected inside the threaded groove 16. A rotating handle 4 is fixedly connected to one end of the bidirectional threaded rod 17.

[0025] Working principle: For this type of positioning pin machining center positioning hole opening device, when the worker needs to clean up fallen metal residue, the motor 11 is started, which drives the large gear 7 to rotate. At the same time, the large gear 7 drives the gear ring 8 to rotate. The gear ring 8 drives the transmission gear 9 to make a circular motion inside the transmission groove 6 under the constraint of the teeth on the inner wall of the transmission groove 6. The transmission rod 12 at the bottom of the transmission gear 9 drives the cleaning block 14 to clean the bottom of the machining frame 2. Because the machining frame 2 has a collection groove 21, the metal debris falls into the collection box 5 through the collection groove 21 for easy cleaning. The metal debris generated by drilling is collected and stored, preventing debris from scattering in the machining area and reducing the frequency of manual cleaning. When it is necessary to clamp the positioning pin, the rotating handle 4 is turned, which drives the bidirectional threaded rod 17 to rotate. At the same time, it drives the support rod 18 to move towards the center, so that the clamping plate 19 can clamp the positioning pin. The surface of the clamping plate 19 is provided with a rubber layer to ensure the fit of the clamping contact surface.
