Clamping assembly for cuboid punching

The invention discloses a clamping assembly for cuboid punching, and relates to the field of drilling toolings, a clamping mechanism is fixed on a supporting assembly, a punching mechanism is correspondingly assembled above the clamping mechanism, the clamping mechanism comprises a workbench, an end face machining clamp is fixed on the top of the workbench, a side face machining clamp is fixed on the rear side wall of the workbench, and the side face machining clamp is fixed on the rear side wall of the workbench. The side face, the end face and the inclined face of a workpiece can be clamped and fixed through the clamping mechanism, punching machining can be conveniently carried out, an additional machine is not needed for carrying out inclined face and through hole forming, resources and cost are saved, the locking assembly can limit and fix the workbench, and the working efficiency is improved. When a workpiece on the working table is drilled, shaking is prevented, or the working table rotates at an angle,
