Electric brush plating device and method for gouges repair for mechanical parts

Abstract

The invention discloses an electric brush plating device and method for gouges repair for mechanical parts. The device comprises a plating pen driving device, a support and a plating solution circulated-supplying device, wherein the plating pen driving device is used for clamping a plating pen and driving the plating pen to rotate, the support is used for fixing a plating piece, and the plating solution circulated-supplying device is used for supplying a plating solution in a circularly-spraying mode; the plating solution circulated-supplying device comprises a solution storage tank; a solution inlet of the solution storage tank is connected with a solution outlet of a solution collecting box, and a solution outlet of the solution storage tank is connected with a solution inlet of a spraying head through a peristaltic pump and a filter; the peristaltic pump is connected with a controller, and the plating pen and the plating piece are respectively connected with the anode and the cathode of a direct current power supply. The method comprises the following steps: starting the plating solution circulated-supplying device; after circulated supplying of solution is stable, starting the plating pen driving device, enabling the plating pen to perform rotation and friction movement close to the gouges part of the plating piece, enabling the plating pen and the plating piece to respectively connect the anode and the cathode of the direct current power supply, and starting electric brush plating operation. The device and the method adopt a mode of spraying the plating solution and rotating the graphite plating pen to rub the gouges parts of the mechanical parts to prepare plating layers so as to repair the gouges parts, and the repairing effect is excellent.

Description

technical field [0001] The invention relates to an electric brush plating device and method, in particular to an electric brush plating device and method used for repairing scratches of mechanical parts. Background technique [0002] There are a large number of hard chrome-plated parts in mechanical parts used in equipment and other fields, such as barrels of artillery, hydraulic cylinders and piston rods in construction machinery, etc. The matrix of the hard chrome-plated part adopts a carbon steel matrix, and a layer of hard chromium coating is plated on the surface of the carbon steel matrix. Hard chromium plating is also called wear-resistant chromium. The chromium plating layer has high hardness and low friction coefficient. Hard chrome plating of mechanical parts can improve its wear resistance and prolong its service life. However, during use, due to stress or improper use, chrome-plated parts will gradually be damaged, and the main forms of damage are local wear, sc...

Problems solved by technology

[0005] Second, it causes waste of chrome plating on undamaged parts

If it is repaired by re-chrome plating, most of the good chrome plating on the parts will be worn away, which will inevitably cause huge waste

[0006] Third, the pollution of chrome plating technology is serious

However, most of the mechanical parts, especially hard chrome-plated parts, are repaired by the traditional manual brush plating method at present. The bruised part is rubbed. This method has the following defects: first, the labor intensity is high and the work efficiency is low; The way of rubbing can't achieve even friction between the graphite-coated pen and the scratched parts, so the repaired coating is unstable and of low quality
