Abstract

The invention discloses a rotatable electroplating rack. The rack comprises main rods, a cross beam, a plurality of gears, gear shafts and fixtures; the main rods are perpendicularly fixed at two ends of the cross beam; hooks are arranged at upper ends of the main rods; a plurality of through holes are formed in the cross beam; one of the gears and a rotating shaft are assembled and then are connected with an output end of a motor through a coupler; the rest gears and the gear shafts are assembled and then penetrate through the through holes; the fixtures used for electroplating of different types of workpieces are arranged at the other ends of the gear shafts; and meanwhile, special fixtures are designed for cylinder block type parts and thin and long shaft type parts particularly, so that the electroplating problems caused by the relatively large mass of the cylinder block type parts and the relatively small diameters of the thin and long shaft type parts are solved. The rack is simple in structure, multiple parts can be electroplated simultaneously, the workpieces are clamped firmly and reliably and are convenient to mount and dismount, the phenomenon of falling into a tank is avoided, the torque is input and the outer meshing gears rotate to drive the workpieces to rotate continuously in the electroplating process, the plating is uniform in thickness, the electric current density is increased, the electroplating time is shortened, and the efficiency is improved.

Description

technical field [0001] The invention relates to an electroplating rack, in particular to a rotatable electroplating rack. Background technique [0002] Electroplating is the process of plating a thin layer of metal or alloy on the surface of a metal substrate by the principle of electrolysis. During electroplating, the plated metal is used as the anode, and the workpiece to be plated is used as the cathode. The cations of the plated metal are reduced on the surface of the workpiece to be plated to form a coating. The solution containing the plating metal cations is used as the electroplating solution to keep the concentration of the plating metal cations constant. The purpose of electroplating is to use the coating on the surface of the substrate to enhance the corrosion resistance, wear resistance, hardness, conductivity, lubricity, heat resistance and other special properties of the metal. It can also be used to repair wear and process False artifacts. [0003] The hange...
