Local electroplating equipment for shaft workpieces Technical Field The utility model relates to the technical field of electroplating, in particular to local electroplating equipment for shaft workpieces. Background Electroplating is a process of plating a thin layer of metal or alloy coating on the surface of some base materials by utilizing the electrolysis principle, so as to change the surface properties of the base materials and play roles in preventing oxidation, rust and the like of the metal. Electroplating is mainly divided into hanging plating, barrel plating, continuous plating, brush plating and other modes, and for large-scale distribution equipment, equipment components are huge, but a conductive contact surface required to be subjected to electroplating treatment is not large, for example, a propeller of an airplane is required to be subjected to local brush plating treatment. Brush plating is also known as plating, and uses a plating metal or other insoluble material as an anode, a workpiece to be plated as a cathode, and cations of the plating metal are reduced to form a plating layer on the surface of the workpiece to be plated. The brush plating process adopts a manual brush plating mode at the beginning, however, the plating quality of a workpiece is difficult to be ensured because the phenomenon of uneven thickness and difficult grasp easily occurs on a plated surface of the manual brush plating, so the manual brush plating mode is gradually eliminated by a brush plating machine, the brush plating machine mainly depends on a pad or brush contacted with an anode to provide electrolyte required by plating, and when the anode is contacted with the surface of a part and moves relatively, metal is deposited on the surface of the part to form a plating layer.
