Abstract

The invention belongs to the technical field of metal surface repair, in particular to a metal shell surface repair process. A surface film plating device in the process comprises a brushing tank, a workpiece fixing device, a brushing device, a driving device, a brushing liquid conveying device and an infrared distance measuring sensor; the workpiece fixing device, the brushing device, the drivingdevice, the brushing liquid conveying device and the infrared distance measuring sensor are automatically controlled through a controller; a cam is arranged in a center hole of a friction wheel; an extrusion plate is slidingly mounted in a chute of the friction wheel; two airbags are symmetrically arranged on the left and right sides under the friction wheel; the lower ends of the airbags communicate through a second one-way valve water spraying disc to realize uniform spraying of electroplating liquid to the upper ends of pieces so as to guarantee the surface plating layer uniformity of workpieces; and when the friction wheel drives the extrusion plate to rotate to the upper half part of the cam, the extrusion plate shrinks into the friction wheel under the effect of elastic force of a spring without influencing the contact of the friction wheel and the surfaces of the workpieces.

Description

technical field [0001] The invention belongs to the technical field of metal surface repair, in particular to a metal shell surface repair process. 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 surface repair process of mechanical parts. [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 intercropping moves relative to each other to complete the coating. When the surface of some metal shells is a curved surface,...
