AI Technical Summary
In the existing technology, the clamping force cannot be accurately controlled during the stamping process of battery casing, resulting in excessive deformation of the material in critical parts and affecting product quality.
A buffer spring and a rubber damping column are installed between the sliding plate and the connecting seat. The buffer spring and the rubber damping column are compressed by the sliding plate sliding on the inner wall of the connecting seat to achieve a buffering effect, avoid excessive clamping force that may cause material deformation, and increase clamping stability with a rubber anti-slip pad.
It effectively prevents the battery casing material from deforming during clamping, improves processing quality and efficiency, and increases clamping stability and safety.
