The connecting shaft 8 is slidably connected with the limiting hole 111 through the adjusting hole 71, thereby adjusting the position of each punching drill bit 15.

[0028] Referring to Figure 8 As shown, the one side of the connecting shell 5 and the positioning plate frame 6 is provided with a limiting hole 111 corresponding to the connecting shaft 8 and the fixed tube frame 9.

[0029] Referring to Figure 8 As shown in the enlarged part, the inner wall of the fixed tube frame 9 is connected with a bearing 91. The inner ring of the bearing 91 is rotatably connected with the driving shaft 13. The bearing 91 will further support the driving shaft 13 to ensure the stability of the long-distance rotation.

[0030] Referring to Figure 5As shown, the auxiliary polishing mechanism includes a stator frame 36 connected to the bottom end of the inner buckle frame 29, and a plurality of coil frames 37 are connected to the inner wall of the stator frame 36. One side of the coil frame 37 is connected with a coil 38. The stator frame 36 is rotatably provided with a clamping unit.

As can be seen from the drawings, a hexagonal hole is formed at the top end of the adjusting bolt 46, which can be twisted by a hexagonal wrench to drive the driving bevel gear 47 to rotate. The driving bevel gear 47 is synchronously rotated with the threaded rod 42 through the engagement with each driven bevel gear 45 to drive the moving block 43 to move synchronously in the same direction or opposite direction. The belt pulley to be processed is placed on the top end of the support frame 40, and then the adjusting bolt 46 is twisted to drive each inner support block 44 to be spread from the inner side of the belt pulley, thereby being extruded and fixed. When the coil 38 is energized to generate a magnetic field, the support frame 40 is driven to rotate with the belt pulley through the cooperation with the permanent magnet 41 on the outer surface of the support frame 40.

[0032] A plurality of sand leakage holes 333 are formed in the bottom surface of the support frame 40, and a guide hole is formed in the top end corresponding to the inner support block 44.

[0034] The implementation principle of the present application is that: when in use, the pulley to be processed is placed on the clamping unit, and the adjusting bolt 46 is twisted to drive each inner support block 44 to fix the pulley from the inside, then the boring hydraulic cylinder 22 is driven to retract to drive the installation plate 3 to move downward, the driving shaft two 20 is started to drive the boring cutter head 21 to bore the center hole of the pulley, after boring, the boring hydraulic cylinder 22 extends to separate the boring cutter head 21 from the pulley, the lower pressure hydraulic cylinder 4 extends to push the connecting shell 5 to move downward, and drives the adjustable drilling mechanism, the position to be drilled can be adjusted in advance before moving downward, and each driving motor 12 drives the drilling bit 15 to rotate to drill under the pushing of the lower pressure hydraulic cylinder 4, after drilling, the current is input to the iron core winding coil 30 to generate a magnetic field, the permanent magnet one 33 is pushed, and the rotating frame 31 is driven to rotate through the rotating ring 32, the outer threaded sleeve kit 28 is driven to move downward through the meshing between the inner threaded frame 34 and the outer threaded sleeve kit 28, the auxiliary polishing mechanism is driven to move downward together through the inner buckle frame 29, the auxiliary polishing mechanism is started to drive the inner clamping unit and the pulley to rotate together, the vibration motor 51 located below is started to drive the polishing sand 48 to be all aimed through the supporting plate 50, so that the rotating clamping unit and the pulley enter the polishing sand 48, after entering, the coil 38 is electrified, and then the pulley is driven to rotate through the clamping unit, and the pulley and the polishing sand 48 particles are rubbed to polish, which can effectively remove the burrs after drilling, and the pulley as a whole can also be polished.
