[0054] The specific usage and function of this embodiment are as follows:

[0055] During the stamping process of the new energy vehicle battery protection board 600, the new energy vehicle battery protection board 600 to be punched is placed on top of the stamping support frame 203, so that the rear end of the new energy vehicle battery protection board 600 contacts the positioning frame a204. Then, the electric telescopic rod a102 is activated through the control panel 500, so that the output shaft of the electric telescopic rod a102 extends. When the output shaft of the electric telescopic rod a102 extends, the rectangular mounting frame 103 drives the plate stamping head 104 to move downward, realizing the automatic opening of the new energy vehicle battery protection board 600. The pressing and riveting rod 107 can only move downward under the action of a ring of rectangular auxiliary blocks 108, which avoids damage to the electric telescopic rod b105 when the new energy vehicle battery protection board 600 is punched, and plays a good protective role for the electric telescopic rod b105.

[0056] During the riveting process of the bolt bushing 700 and the new energy vehicle battery protection board 600, the servo motor 301 is started via the control panel 500, causing the drive screw 302 to move the movable limit seat 201.

After that, the punched new energy vehicle battery protection board 600 is placed on the circular positioning ring 206 and the positioning frame b207, so that the bolt bushing... The top of the bolt bushing 700 is inserted into a punch hole in the battery protection board 600 of the new energy vehicle, which plays a positioning role for the battery protection board 600 and the bolt bushing 700, making the connection between the battery protection board 600 and the bolt bushing 700 more precise. Then, the electric telescopic rod a102 is activated through the control panel 500, which extends the output shaft of the electric telescopic rod a102. When the electric telescopic rod a102 drives the pressing rod 107 to move downward, the pressing rod 107 can push a circular force rod 404 to move outward, so that the top of the bolt bushing 700 can deform locally, realizing the pressing connection between the bolt bushing 700 and the battery protection board 600 of the new energy vehicle. When the electric telescopic rod a102 drives the pressing rod 107 to move upward, the pressing rod 107 separates from the circular force rod 404, and the inclined pushing block 402 can return to its original position under the action of a coil spring 406.

[0057] After processing is completed, the servo motor 301 is started through the control panel 500, which causes the drive screw 302 to drive the movable limit seat 201 to reset. When the circular pressing column 202 presses the detection button 106 again, the control panel 500 controls the output shaft of the electric telescopic rod b105 to move in the opposite direction, and can automatically switch the processing mode according to the position of the movable limit seat 201.
