Self-positioning clamping mechanism for automobile part production and punching device of self-positioning clamping mechanism

The invention provides an auto spare part production self-positioning clamping mechanism and a punching device thereof, and belongs to the technical field of auto spare part production, the auto spare part production self-positioning clamping mechanism comprises a workbench, a first clamping part is mounted on the workbench, a second clamping part is mounted on the first clamping part, a linkage part is mounted at the lower end of the first clamping part, and a driving part is mounted at the lower end of the linkage part. The punching device solves the problems that when an existing punching device for production of the automobile parts is used for punching, the automobile parts need to be stably clamped, but the clamping mode is generally driven by power equipment such as a motor or an air cylinder, the automobile parts are prone to being damaged by clamping, the defective rate of the automobile parts in the production process is increased, and the production cost is lowered. And the production cost is furth
