[0026] S5: At this time, the lifting plate continues to descend, driving the punching head to descend, and at the same time the position of the rubber plate does not change, then the telescopic rod retracts the internal compression spring of the sleeve column, so that an extrusion force is generated between the rubber plate and the car bumper, and the rubber plate is deformed accordingly according to the surface of the car bumper so that it is closely attached to the car bumper;

[0027] The C-shaped support frame and the mounting box support the bottom of the car bumper, and the rubber plate close to the surface of the car bumper limits its up and down position. The friction between the rubber plate and the car bumper can also prevent the car bumper from moving forward and backward, so that the position of the car bumper can be positioned from all directions to prevent it from shifting during the punching process, further ensuring the accuracy of the punching position.

[0028] S6: The punching head descends to punch holes at the punching position of the automobile bumper, and the waste chips generated by the punching fall from the chip drop port into the chip collection box for storage.

[0029] The beneficial effects of the present invention are: the punching position on the automobile bumper can be centered to prevent the punching position from being misaligned; and the position of the automobile bumper can be positioned in all directions from left to right, front to back, and up to down to prevent it from shifting during the punching process, thereby further ensuring the accuracy of the punching position.
