Metal piece surface electroplating equipment and electroplating process

The invention relates to the technical field of metal electroplating, and particularly discloses metal part surface electroplating equipment and electroplating technology.The metal part surface electroplating equipment comprises an electrolytic tank and a sliding frame installed on the electrolytic tank, a sliding rail is fixedly installed at the side end of the electrolytic tank, the sliding frame is installed on the sliding rail in a sliding mode, and a first sliding groove is formed in the surface of the sliding frame; the two clamping plates no longer clamp and fix the metal piece body, at the moment, the metal piece body falls into the two limiting pieces through the gravity of the metal piece body, and at the moment, the surfaces, making contact with the metal piece body, of the two clamping plates are exposed outside. The electroplating liquid in the electrolytic tank can perform electroplating treatment on the original contact surface of the clamping plate and the metal part body, so that the situatio
