Auxiliary fixture for vacuum interrupter assembly

Abstract

The invention discloses an auxiliary clamp for vacuum arc extinguishing chamber assembly. The clamp comprises a support frame and an auxiliary clamp, wherein the support frame comprises a support bottom plate; a support side plate in vertical upward arrangement is molded in the middle part of the left end of the upper end surface of the support bottom plate; a support connecting plate is shaped inthe middle part of the right end surface of the support side plate; the auxiliary clamp comprises a circular arc-shaped sliding support plate; the middle part of the outer cylindrical surface of thesliding support plate is fixed at the right end of the support connecting plate; a pair of auxiliary protection plates in symmetrical arrangement are slidingly arranged on the inner cylindrical surface of the sliding support plate; a circular arc-shaped position limiting support plate is molded at the bottom of the sliding support plate; a cylindrical limiting post which is in the radial directionand is in rightward arrangement is molded on the inner cylindrical surface of the limiting support plate; a cylindrical moving limiting post is arranged on the bottom surface of the auxiliary protection plate. The auxiliary clamp has the advantages that the structure is simple; the operation is convenient; after the installation and clamping of the vacuum arc extinguishing chamber is completed, apair of auxiliary protection plates are merged to be combined with the sliding support plate to surround the arc-extinguishing chamber main body; the damage to the arc-extinguishing chamber main bodyis avoided.

Description

Technical field [0001] The invention relates to the technical field of manufacturing a vacuum interrupter, in particular to an auxiliary clamp for assembling a vacuum interrupter. Background technique [0002] At present, in the production of circuit breakers, the assembly of the vacuum interrupter is generally performed by workers placing various parts on the ground, holding the main body of the interrupter with their hands, and then installing the upper bracket, lower bracket, conductive clip, and insulating rod. To the main body of the interrupter. Since the vacuum interrupter is generally made of porcelain, it is easy to break, and workers will break the interrupter if they are not careful during installation. Workers must use tools to assemble the interrupter while holding on to the interrupter, and they need to be especially careful to avoid breaking the interrupter. This is very inefficient and the assembly quality is poor. At the same time, the damage rate of the interru...

AI Technical Summary

Problems solved by technology

Since the vacuum interrupter is generally made of porcelain and is easily broken, workers will break the interrupter if they are not careful during installation.

Workers need to use tools to assemble the arc extinguishing chamber while supporting it, and they need to be careful not to break the arc extinguishing chamber, so the work efficiency is very low, and the quality of assembly is poor, and the damage rate of the arc extinguishing chamber is also very high
