Brush electroplating device and method for repairing part hole

Abstract

The invention provides a brush electroplating device and method for repairing a part hole. The device comprises a support, two sets of plating pen clamping assembles, two plating pens, a driving assembly, a brush plating power source and a check ring. The support comprises a base, supporting legs, a lifting platform and a liquid draining nozzle. Each plating pen clamping assembly comprises a clamping disk, a balance clamping piece and an installing and connecting column. Each plating pen comprises a clamping part, an insulating part, a conductive shaft shoulder, a working part and a plating liquid input nozzle. The driving assembly comprises a driving motor, a rotating shaft, a rotary table and a workpiece fixing piece. The plating pens are fixedly installed through the plating pen clamping assemblies. The machining method includes the steps of electric purification machining, weak activation machining, strong activation machining, brush electroplating and the likes. The brush electroplating device is simple in structure, workpieces to be machined can be installed and adjusted conveniently, work efficiency for brush electroplating is high, the machining effect is good, and the service life of the plating pens is long.

Description

technical field [0001] The invention relates to the metal surface engineering field of electric brush plating technology, in particular to an electric brush plating device and method for repairing inner holes of parts, which are suitable for repairing and remanufacturing inner hole damaged parts. Background technique [0002] Brush plating technology is a kind of electroplating in surface remanufacturing technology. It uses electrochemical deposition method to quickly obtain high-performance smooth and dense electroplating layer locally on the surface of metal workpieces. This technology can restore the dimensional accuracy and geometric shape accuracy of worn parts, fill the scratches on the surface of the parts, and improve the wear resistance, electrical conductivity, high temperature resistance and anti-corrosion performance of the parts surface. At present, brush plating technology has been widely used in many fields such as aerospace, railway transportation, hydraulic ...

AI Technical Summary

Problems solved by technology

However, at present, manual brush plating is usually used to repair inner hole parts. The disadvantages are: manual brush plating is labor-intensive, and the work efficiency of brush plating is low; Partial contact is uneven, coating quality is not high

In response to this problem, there have been electric brush plating devices and methods for automatically implementing parts inner hole repair by electric means, such as the Chinese company whose publication number is CN101514468A and the invention title is "Device and method for brush plating of inner hole parts". The patent literature provides a device and method for repairing inner hole parts by electric brush plating technology, however, this method has certain limitations and deficiencies
