Grabbing mechanism for stamping parts with complex shapes

The invention belongs to the technical field of automatic equipment, and particularly relates to a grabbing mechanism for stamping parts with complex shapes. The device comprises a grabbing limiting machine base, a driving fixing plate table is arranged on the grabbing limiting machine base, a lower corner hinge frame support limiting and fixing assembly capable of doing reciprocating rectilinear motion in the vertical direction is arranged below the driving fixing plate table, and a lifting driving piece is arranged on the driving fixing plate table. When the lower corner hinge frame support is grabbed, the lower corner hinge frame support is placed below the lower corner hinge frame support limiting and fixing assembly, at the moment, the lifting driving piece is started, the lower corner hinge frame support limiting and fixing assembly is driven by the lifting driving piece to descend, and the lower corner hinge frame support is grabbed. The lower corner hinge frame support is limited through the lower cor
