Plating pen for brush electroplating of shafts

Abstract

The invention discloses a plating pen for brush electroplating of shafts. The plating pen comprises: a sleeve and plating pen brushes, wherein the inner wall surface of each of the plating pen brushes is provided with brush hair, and the plating pen brushes are circumferentially uniformly arranged in the inner bores of the sleeve through a variable diameter mechanism; and the variable diameter mechanism comprises: circular ring seats, wherein the three circular ring seats are axially equidistantly arranged in the inner bores of the sleeve, one of the circular ring seats is fixedly arranged, and the other two circular ring seats are arranged in an axial sliding mode; a plating pen brush support comprising telescoping rods and two connecting rods, wherein one ends of the telescoping rods are fixed to the middle circular ring seats respectively, the other ends of the telescoping rods are fixed to the middle portions of the outer wall surfaces of the plating pen brushes respectively, one ends of the two connecting rods are hinged to the circular ring seats at two sides respectively, and the other ends of the two connecting rods are hinged to the central portions of the outer wall surfaces of the plating pen brushes respectively; and a driving mechanism used for driving one of the circular ring seats capable of axially sliding to slide. The plating pen can realize mechanical brush electroplating of shafts and other parts with different diameters, has a high efficiency, and can guarantee the quality of the brush electroplating.

Description

technical field [0001] The invention relates to the field of electric brush plating, in particular to a plating pen for electric brush plating on a shaft. Background technique [0002] The damage of shaft parts in mechanical equipment is a common damage fault. The damage of shaft parts is mainly the local axial damage of the outer surface. These surface damages can be repaired by brush plating to reduce the waste of resources and improve the shaft quality. The service life of parts saves cost. [0003] At present, the brush plating of the shaft is mainly carried out manually. The operator needs to measure while brushing to ensure that the size of the repaired shaft can meet the requirements, and it is necessary to avoid peeling or scratching of the coating. Therefore, completing brush plating manually will result in a large amount of manpower, material and financial resources, and the manual brush plating process is labor-intensive, low in efficiency, and requires high skil...
