Electroplating brush device

Abstract

The invention belongs to the technical field of surface electroplating, and particularly relates to an electroplating brush device. The electroplating brush device comprises a brush application tank,a workpiece fixing device, a brush application device, a drive device, a brush application liquid conveying device and an infrared distance measuring sensor. A controller is used for automatically controlling the workpiece fixing device, the brush application device, the drive device, the brush application liquid conveying device and the infrared distance measuring sensor. A cam is arranged in a center hole of a friction wheel, an extrusion plate is arranged in a sliding groove of the friction wheel in a sliding manner, two air bags are symmetrically arranged on the left side and the right side below the friction wheel, the lower ends of the air bags are connected with second one-way valves, the second one-way valves communicate with water spraying discs, the water spraying discs are fixedly connected to the middle portions of hair bundles, electroplating liquid is evenly sprayed to the upper ends of the hair bundles, and accordingly the uniformity of a workpiece surface clad layer isguaranteed; and when the friction wheel drives the extrusion plate to the upper half part of the cam, the extrusion plate contracts into the friction wheel under the action of elasticity of springs, and accordingly contact between the friction wheel and the workpiece surface cannot be influenced.

Description

technical field [0001] The invention belongs to the technical field of surface electroplating, in particular to an electroplating brush device. Background technique [0002] Brush plating technology is a special form of electroplating technology. It mainly applies the principle of electrochemical deposition to rapidly deposit metal coatings on selected parts of the surface of conductive workpieces. The size and geometric accuracy of the workpiece can be repaired, and the surface of the workpiece can be strengthened to improve the service life. The brush plating technology has been widely used in the maintenance and remanufacturing of mechanical equipment. [0003] In the prior art, the workpiece is mainly connected to the negative pole of the power supply as the cathode; the plating pen is connected to the positive pole of the power supply as the anode; The relative movement of the intercropping completes the coating. Because the hair bundles on the anode of the plating pe...

Problems solved by technology

[0005] This technical scheme can realize surface brush plating treatment on curved surface workpieces, but the hair bundles connected to the anode of the plating pen in this device cannot be bent according to the degree of curvature of the curved surface on the workpiece, thereby affecting the quality of the coating after brush plating of the hair bundles. Uniformity, which affects the quality of the workpiece; and in this scheme, the electroplating solution cannot be evenly sprayed on the upper end of the hair bundle, which will also affect the uniformity of the coating on the surface of the workpiece
