[0002] The battery protection board of new energy vehicles needs to withstand high-frequency vibration and mechanical stress. The press-fit assembly technology forms an interlocking structure through plastic deformation, which can ensure a firm connection between the bolt bushing and the battery protection board of new energy vehicles and prevent loosening.

[0003] Currently, the following problems still exist when assembling bolt bushings with the battery protection board of new energy vehicles using press-fitting: 1. The punching and riveting processes need to be processed on two separate machines, which takes up time during workpiece turnaround and affects production efficiency; 2. The processing method cannot be automatically adjusted according to the positioning situation, which can easily lead to confusion between the punching and riveting processes; 3. Generally, the lack of auxiliary support structure makes it impossible to accurately control the deformation position of the workpiece during riveting, which affects the riveting processing accuracy.

[0027] The specific usage and function of this embodiment are as follows: 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.

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 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.
