Abstract

The invention relates to a vacuum arc-extinguishing chamber assembling calibration clamp. The vacuum arc-extinguishing chamber assembling calibration clamp comprises a calibration unit used for calibrating a single vacuum arc-extinguishing chamber. The calibration unit comprises a movable end positioning pin and a static tube core positioning structure which are coaxially arranged in an up and down direction. The movable end positioning pin is used for inserting and connecting to the threaded hole of a movable tube core in a coaxial and positioning mode. The static tube core positioning structure is used for assembling with a static tube core in the coaxial and positioning mode. A righting structure used for righting the vacuum arc-extinguishing chamber is arranged above the static tube core positioning structure. During vacuum arc-extinguishing chamber assembling, the static tube core positioning structure and the static tube core are installed in the coaxial and positioning mode. Themovable end positioning pin is coaxially inserted and connected to the threaded hole of the movable tube core. The coaxiality of the static tube core and the movable tube core is guaranteed, the righting structure can carry out righting and positioning on a static cover plate, a porcelain shell and other components, and a problem that the coaxiality of the vacuum arc-extinguishing chamber can not be guaranteed in the prior art is solved.

Description

technical field [0001] The invention relates to a jig for assembling and calibrating a vacuum interrupter. Background technique [0002] The key component of the vacuum circuit breaker is the vacuum interrupter, which determines the main performance of the vacuum circuit breaker. Vacuum interrupter includes static cover plate, static tube core, porcelain shell, moving tube core, moving cover plate, etc., and the concentricity of the whole tube of vacuum interrupter affects the contact resistance and co-current effect of the product. Therefore, in the process of When assembling the vacuum interrupter, there is a high coaxiality requirement for each component. The assembly and positioning of the existing vacuum interrupter generally depends on the self-positioning of the parts or alignment by the experience of the assembler. However, the above method is prone to unqualified coaxiality and dislocation of dynamic and static contacts in the assembly accuracy of the vacuum inter...
