The positioning ring 66 locates the drilling position to ensure the position accuracy of the drill bit 62 during the drilling process. The rubber ring 67 contacts the surface of the workpiece during drilling to prevent the positioning ring 66 from moving.

[0044] The positioning buffer 64 includes a first rotating rod 641 and a second rotating rod 642.

[0049] When in use, the operator places the mechanical parts to be processed in the placement groove 26 of the placement platform 24, and starts the clamping cylinder 302. The telescopic end of the clamping cylinder 302 pushes the slide block 304 to slide on the first slide block 303. The slide block 304 drives the rack 305 to move. The rack 305 meshes with the transmission gear 307 to rotate the transmission gear 307. The transmission gear 307 drives the clamping rod 309 to slide on the second slide block 308, so that the first arc clamping block 306 and the second arc clamping block 311 firmly clamp the workpiece.
