A kind of output shaft chrome plating method

Abstract

The invention provides an output shaft chrome plating method and an output shaft chrome plating fixture. An output shaft comprises a cylindrical main body, and an outer circle area for chrome plating and an inner circle area for chrome plating are arranged at the first end of the main body. The fixture comprises a fluororubber sleeve, a lower cover plate, an upper cover plate and an anode center pole, the fluororubber sleeve shields an inner circle surface of a non-chrome-plating window area, and the anode center pole is connected with the upper cover plate and the lower cover plate. An insulating sleeve is arranged at the joint between the anode center pole and the upper cover plate. According to the chrome plating method, the special chrome plating fixture is provided, integral assembly and suspension are adopted, component matching tightness is achieved, anode positions for inner circle plating are fixed, the plating thickness of an inner circle is uniform, and the phenomenon that part of a chromium layer of an inner hole is too thin to grind is prevented; the method is simple and rapid to operate, the inner circle and an outer circle can be plated with chrome by the same fixture at a time, processing cycle of components is shortened greatly, repair rate of the components is reduced and production efficiency is improved.

Description

technical field [0001] The invention relates to a chrome-plating method and a special fixture thereof, in particular to a chrome-plating method for an output shaft with a cylindrical structure. Background technique [0002] figure 1 It shows a structural diagram of an output shaft. The output shaft has a cylindrical structure. There are four small holes in the chrome-plated part of the part. The small holes need to be protected from chrome plating. Lead strips are used for protection. Cutting with a blade and grinding with sandpaper is a cumbersome operation, and if the residual lead is not polished cleanly, there will often be chromium collapse at the position of the small hole, which will affect the delivery of parts. [0003] Moreover, the structure of the output shaft is complex. During the chrome plating process, the inner circle needs to be plated first and then the outer circle. The protection of the parts is cumbersome and time-consuming, and the position of the ano...

Problems solved by technology

[0005] Specifically, the present invention provides a chrome-plating method and fixture for the output shaft to solve the problem of chrome leakage at the window and end face, chrome collapse at the edge of the small hole and inner circle chrome due to poor protection during the local chrome plating of the inner hole and outer circle of the output shaft. Uneven layer thickness, resulting in long processing cycle and high repair rate
