Problems solved by technology
[0005] The electro-brush plating repair device in this technical solution can realize the electroplating treatment of inner hole parts, but the inner hole brush-plating special plating pen in this device and the axis of the inner hole of the workpiece to be plated can only be realized by means of a tooling fixture. Positively, the production cycle of fixtures is long, and different fixtures need to be made according to different workpieces to be plated, thus increasing the cycle and cost of electroplating processing; also because of the need for fixtures, the device cannot be used in a more free environment use, such that the use of the device is limited

Abstract
The invention belongs to the technical field of engine connecting rod repairing, and particularly relates to an electro-brush plating repairing method of an automobile engine connecting rod. An electro-brush plating repairing device in the method comprises a base, a top cover, bolts, sealing rings, an electroplating brush, a rotating shaft, rolling wheels, rotary supporting shafts, supports, sliding blocks, springs, a fixing sleeve, a motor and a locking module. According to the electro-brush plating repairing method, the three supports are evenly distributed on a cylindrical face of the fixing sleeve, the other ends of the supports are rotationally connected with the rolling wheels through the rotary supporting shafts, the two ends of the rotary supporting shafts are fixedly connected into installation holes of the upper sliding block and the lower sliding block, the sliding blocks are connected into rectangular grooves in the supports in a sliding manner, automatic coinciding of theaxis of the rotating shaft and the axis of an inner hole of the top cover is achieved, and finally, it is guaranteed that the electroplating brush evenly smears an electroplating solution to the innerwall of a workpiece to be plated; and the manner is also suitable for the temporary job at the site, without assistance of a tool fixture, the inner hole of the workpiece to be plated can also be repaired within a very short time, and operation is convenient.
Description
technical field [0001] The invention belongs to the technical field of repairing engine connecting rods, in particular to a method for repairing automobile engine connecting rods by electric brush plating. Background technique [0002] The connecting rod of the engine is one of the important parts of the engine. The failure of the connecting rod is mainly due to wear and deformation that cannot meet the size requirements. Therefore, the repair of the connecting rod is mainly to restore its matching size and surface properties. The repair technology currently used is mainly repaired by electric brush plating. [0003] Brush plating is a surface processing technology that uses electrochemical methods to reduce metal ions to metal and deposit them on the surface of metal or non-metal products to form a smooth and dense metal coating that meets the requirements. With the development of science and technology and production, brush plating technology involves more and more fields...
