An electric brush plating device for repairing hole-like workpieces

Abstract

The invention relates to an electric brush plating device for repairing hole-like workpieces, comprising a motor bracket, a fixed support is connected to the lower end of the motor support, fixing screws are installed on the fixed support, and a motor is connected to the upper end of the motor support. The output shaft is connected with a pen holder swivel that passes through the motor bracket. A positioning rod is installed on the pen holder swivel. One end of the positioning rod is set with a cylindrical helical compression spring. In the spring seat of the pen holder swivel, the hexagonal nut supported on the spring seat is threadedly connected to the positioning rod. A screw for the pen on which a spacer is mounted between the positioning rod and the brush-plated pen. The invention adopts mechanical automatic brush plating instead of manual work, greatly reduces labor intensity, shortens brush plating time, effectively reduces production cost, and is beneficial to ensure product quality.

Description

technical field [0001] The invention relates to the technical field of electric brush plating, in particular to an electric brush plating device for repairing hole-like workpieces. Background technique [0002] At present, when repairing some unremovable or difficult-to-disassemble hole-type workpieces due to wear or manufacturing, the method of brush plating is often used. The brush plating process is realized by hand, and the operator holds a brush plating pen to dip an appropriate amount of brush plating solution, and moves in a circular motion against the inner surface of the hole. The process requires a certain speed and requires uniform rotation. Especially when repairing hole-like workpieces that cannot be disassembled or are difficult to disassemble, the operator not only has to bear the weight of the brush plating pen and maintain a uniform motion, but sometimes also needs to maintain a certain body posture. [0003] However, this kind of working method requires a...

Problems solved by technology

[0003] However, this kind of working method requires a lot of labor. For an operator with normal physical strength, the time required to maintain this operation will not exceed half an hour. In actual production, the thickness of the coating is relatively large, and brush plating It takes a long time and usually requires two to three people to take turns to operate, so there is a gap period, which makes quality control more difficult and production costs higher
