Precision hardware stamping part surface treatment device

The utility model discloses a precision hardware stamping part surface treatment device, belongs to the technical field of hardware part surface treatment, and solves the problems that according to an existing device, after the fixing angle of hardware parts is manually adjusted, the other side faces of the hardware parts can be polished, operation is tedious, and machining efficiency is reduced. A first groove is formed in the top face of the transverse plate in a penetrating mode, a first driving assembly used for driving the first sliding block is arranged in the first groove, a hydraulic cylinder is fixedly installed on the bottom face of the first sliding block, and a mounting plate is fixedly installed at the output end of the hydraulic cylinder. Two penetrating second grooves are symmetrically formed in the two sides of the top face of the mounting plate, a clamping assembly and a polishing assembly are arranged below the mounting plate, and the top face and the periphery of the hardware can be polishe
