[0002] The high-voltage vacuum circuit breaker assembly tooling is a special device used to fix the circuit breaker housing and assist in the assembly of components during the manufacturing process of high-voltage electrical equipment. This tooling typically includes a base support frame, a housing clamping device, and necessary positioning elements. In the traditional production process, it is mainly used to keep the housing stable, allowing operators to perform a series of assembly processes such as arc-extinguishing chamber installation and mechanism adjustment. This type of tooling provides the necessary positioning reference and work platform for circuit breaker production, and is an important process equipment that ensures the precision of basic assembly.

[0003] The existing high-voltage vacuum circuit breaker assembly tooling generally adopts a fixed structure design, with the spacing and height of its clamping mechanism being non-adjustable.
