[0013] Beneficial effects of the utility model:

[0014] 1. According to the previous punching device, for direct clamping and positioning, it is not easy to clamp and position the plate due to the curved state, so that the clamping becomes loose and needs to be adjusted repeatedly, which reduces the overall punching effect. What is different is that, by using the punching control component, which is arranged above the workbench, the left door sill inner plate reinforcement plate of the car can be processed and punched. Through the displacement component, which is arranged on both sides of the workbench, the punching control component can be slidably driven to rise and fall.

[0015] 2. When positioning, place the left door sill inner plate reinforcement plate on the positioning table. The mounting holes can be used for pre-installation and positioning to complete pre-positioning. According to the curved state of the left door sill inner plate reinforcement plate, push the extension rod through the first slide to displace along the second arc groove. The positioning bolt drives the telescopic sleeve to press its pressure plate on the reinforcement plate for positioning. Synchronously, the first spring module drives the first guide wheel to displace. Since the arc directions of the first arc groove and the second arc groove are different, corresponding to the curved state of the reinforcement plate, the second slide displaces along the first arc groove, and the first adjusting rod retracts and retracts along the inside of the adjusting box, driving the clamping plate to clamp on the outside of the reinforcement plate. The pin passes through the upper limit holes of the first adjusting rod and the second adjusting rod in turn into the positioning hole to complete the positioning. BRIEF DESCRIPTION OF THE DRAWINGS
