[0002] Copper busbar, also known as copper busbar or copper busbar, is usually made of pure copper or copper alloy. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. Copper busbar is mainly used as busbar in electrical equipment and is widely used in high and low voltage switchgear. Copper busbar needs to be punched according to installation requirements before installation.

[0003] At present, most workers use punching machines to punch copper busbars. Workers usually mark the punching positions on the copper busbars first. A laser transmitter is set under the drill bit of the punching machine to project a laser positioning point.

However, the positioning process is performed manually, and unskilled workers may need a long time to overlap the marked point with the laser positioning point. In addition, the copper busbar is not limited after positioning. If it shakes due to accidental touch by the workers during the drilling process, it is easy to cause hole position deviation. Therefore, it is urgent to design a switch cabinet copper busbar punching device to solve the above problems. Utility Model Content
