Problems solved by technology
Conductive rods with steps and wrench grooves are not easy to brush-plate, and it takes a long time to brush-plate the end faces of the steps and wrench grooves to brush-plate nickel, and the work efficiency is low. It is easy to brush-plating, and some can’t even brush-plate nickel. The one-time pass rate of brush-plating is relatively low, about 50%, and the labor intensity increases.
At present, the brush nickel plating of the vacuum interrupter is mostly manually operated, and the brush nickel plating of the metal parts at both ends requires repeated work by many people. Manual brush plating is likely to cause inconsistent thickness of the coating, and the operation of multiple people is likely to cause the coating to be worn out. Copper exposure

Embodiment Construction
[0010] When the present invention is used, such as figure 1 Place the vacuum interrupter on the ring electrode 3, and place one end of the conductive rod downwards. The conductive rod passes through the hole in the center of the ring electrode 3 and the ring positioning plate 2 and extends into the electroplating solution. The cup electrode 1 passes through the electrode connecting bar. One 5 and the wire are connected to the positive electrode of the power supply; the ring electrode 3 is connected to the metal surface of the vacuum interrupter, the electrode connecting bar on the ring electrode 3 is connected to the negative electrode of the power supply through a wire; the brush electrode 4 is connected to the positive electrode of the power supply through the wire Connect, to facilitate brush plating, the brush plating electrode 4 is wrapped with sponge or similar objects; turn on the power and dip the wrapped brush plating electrode 4 in the plating solution to brush the end...

The invention discloses a device for performing nickel electroplating and nickel brush plating simultaneously on a vacuum arc-extinguishing chamber. The device is characterized by comprising a cup-shaped electrode (1), an annular positioning disc (2), an annular electrode (3) and a brush plating electrode (4), wherein the cup-shaped electrode (1) is fixedly arranged in an electroplating tank; the annular positioning disc (2) is positioned above the cup-shaped electrode (1); and the annular electrode (3) is fixedly arranged above the annular positioning disc (2). According to the device, a nickel electroplating process of the vacuum arc extinguishing chamber is simplified, and electroplating and brush plating are simultaneously performed on metal components at two ends of the vacuum arc extinguishing chamber, so that the operation time is saved, the entire process can be independently finished by one person, and the human resources are saved; and the vacuum arc extinguishing chamber in the electroplating process does not require to be rotated or moved, so that damages caused to a plating by rotation and movement of the vacuum arc extinguishing chamber are avoided.
Description
Technical field [0001] The invention relates to a device for simultaneous nickel electroplating and nickel brush plating in a vacuum interrupter, belonging to the technical field of electroplating. Background technique [0002] The vacuum interrupter is the core component of the main control and protection equipment for power transmission and distribution equipment and power systems, and is widely used in electric power, machinery, metallurgy, masonry, mining, electrical railways and other fields. The middle part of the vacuum interrupter is a ceramic shell, and the two ends are exposed metal components. Because the environment of the vacuum interrupter is more complicated, it is usually used when high temperature and low temperature continue to alternate, or when the ambient humidity is high. , Which makes the metal components easy to be corroded and affects the service life of the vacuum interrupter. Therefore, the metal part of the vacuum interrupter is usually plated with nic...
