[0022] It should be noted that the clamping mechanism 5 includes a clamping pressure plate 51, a return spring 52 and an unlocking assembly 54. The clamping pressure plate 51 is provided with several mounting grooves evenly distributed on the circumference of the mounting tube 6. The clamping pressure plate 51 is hinged to the mounting tube 6 through a pin shaft. One end of the return spring 52 is connected to the inner wall of the mounting groove, and the other end is connected to the side of the clamping pressure plate 51. The top of the clamping pressure plate 51 is provided with an extrusion slope 53. The unlocking assembly 54 is provided in the mounting tube 6 and is used to loosen the clamped clamping pressure plate 51.

[0023] In addition, the unlocking assembly 54 includes a clockwork spring 542, an unlocking plate 545, a driving disk 543 and a driving shaft 541. The driving shaft 541 is rotatably connected to the mounting tube 6. One end of the clockwork spring 542 is connected to the driving shaft 541, and the other end is connected to the mounting tube 6. The driving disk 543 is fixed on the driving shaft 541 and has a number of arc-shaped driving grooves 544 evenly distributed thereon. The unlocking plate 545 corresponds one-to-one to the clamping pressure plate 51 and is slidably connected to the guide plate 546 in the mounting tube 6. A through hole corresponding one-to-one to the unlocking plate 545 is provided on the inner wall of the mounting tube 6, and an insert rod 547 is provided on the unlocking plate 545 to be inserted into the arc-shaped driving groove 544.

[0024] In addition, the stamping mechanism 7 includes a hydraulic cylinder 71 , a support frame 72 and a stamping die 73 .

[0026] Specific implementation and principle:

[0027] When the present invention is actually used, the unpunched bearing bracket 9 is placed on the positioning frame 4 of the turntable, and the bearing bracket 9 is pressed downward. The clamping pressure plate 51 is driven to rotate by the extrusion inclined surface 53 on the clamping pressure plate 51, and the return spring 52 is compressed. When the bearing bracket 9 is at the bottom of the clamping pressure plate 51, under the action of the elastic force of the return spring 52, the clamping pressure plate 51 rotates in the opposite direction to press and fix the bearing bracket 9. Then the piston rod of the hydraulic cylinder 71 is controlled to extend, and the bearing bracket 9 is punched by the punching die 73 on the piston rod. The waste generated by the punching falls onto the processing table 1 through the punching hole 41 of the positioning frame 4 and the discharge hole 31 of the turntable 3. When the punching of the bearing bracket 9 is completed, the output shaft of the control motor 81 is rotated, and the pulley 1 82 on the output shaft drives the rotating shaft 2 and the pulley 2 83 to rotate through the belt 84, and the bearing bracket 9 on the turntable 3 rotates accordingly. The locking plate 545 is then released and the locking plate 546 is released, and the locking plate 547 is released to lock the locking plate 547. The locking plate 547 is released and the locking plate 546 is released.

[0028] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the present invention, or the present utility invention and technical solution are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
