Description

Technical Field

[0001] This utility model relates to the field of door lock bracket processing technology, and in particular to a quick punching mechanism for door lock brackets. Background Technology

[0002] There is a door lock bracket with the following specifications. Fig. 1-2 As shown, the structure is symmetrical and includes a motherboard and an L-plate fixedly connected to the motherboard. One end of the motherboard has a first through hole b1, a second through hole b2, a third through hole b3, and a fourth through hole b4, with the centers of the four holes arranged in a square shape. The first through hole b1, the second through hole b2, the third through hole b3, and the fourth through hole b4 are symmetrically arranged along the center line of the length direction. The other end of the motherboard has a fifth through hole b5 along the center line of the length direction. The first through hole b1, the second through hole b2, the third through hole b3, the fourth through hole b4, and the fifth through hole b5 have the same size. The end of the motherboard near the fifth through hole b5 is convex in shape. Currently, the machining of the five through holes in this door lock bracket is mostly done manually using a bench drill. For each through hole, a separate workpiece positioning mechanism needs to be designed to match that hole. This workpiece positioning mechanism restricts the movement of the door lock bracket. Multiple workpiece positioning mechanisms need to be designed for the five holes, and different workpiece positioning mechanisms need to be frequently replaced and installed to achieve the drilling operation of these five through holes. This is time-consuming, labor-intensive, costly, and inefficient. Utility Model Content
