A kind of assembly process and assembly tooling of the contact pressure spring of the arc extinguishing chamber

Abstract

The invention provides an assembly process and assembly tool for the contact pressure spring of the arc extinguishing chamber. During assembly, the arc extinguishing chamber is rotated in the circumferential direction of the arc extinguishing chamber to determine the position of the threaded hole at the static end of the arc extinguishing chamber, and Fix the spring barrel and the moving contact rod of the arc extinguishing chamber together, put the contact compression spring and the tie rod joint in the spring barrel, and find the orientation of the pin hole of the tie rod joint so that the pin shaft of the tie rod joint on the tie rod joint The positional relationship between the hole and the threaded hole at the static end of the arc extinguishing chamber in the circumferential direction of the arc extinguishing chamber meets the design and assembly requirements; the compression spring of the contact is driven to compress and deform by pressing the tie rod joint, and fixedly assembled on the spring barrel to stop and cooperate with the tie rod joint The fixed stopper is used to limit the contact compression spring at its maximum release stroke to complete the contact compression spring assembly. The entire assembly process can conveniently compress the contact pressure spring and ensure that the pin shaft hole of the tie rod joint and the threaded hole of the static end have a qualified positional relationship.

Description

technical field [0001] The invention relates to an assembling process and an assembling tool for a contact pressure spring of an arc extinguishing chamber. Background technique [0002] The high-voltage switch uses the arc extinguishing chamber as the breaking unit. In order to reduce the contact resistance of the moving and static contacts of the arc extinguishing chamber when closing and ensure the closing stability of the moving and static contacts, it is necessary to arrange contact pressure on the moving contact end of the arc extinguishing chamber. spring assembly. The contact compression spring assembly includes the contact compression spring, the tension rod joint hinged with the tension rod, and the spring cylinder fixedly assembled with the moving contact of the arc extinguishing chamber. In this way, the insulating pull rod applies a thrust to the contact compression spring through the pull rod joint, and the contact compression spring drives the moving contact t...

Problems solved by technology

[0004] The purpose of the present invention is to provide an assembly process for the contact pressure spring of the arc extinguishing chamber, so as to solve the problem that the contact pressure spring in the prior art cannot ensure the pin hole of the tie rod joint on the tie rod joint and the arc extinguishing after the assembly of the contact pressure spring on the arc extinguishing chamber is completed. The positional relationship of the threaded holes at the static end of the arc extinguishing chamber in the circumferential direction of the arc extinguishing chamber satisfies the technical problem of the design and assembly requirements; at the same time, the invention also provides an assembly tool for the contact compression spring of the arc extinguishing chamber to ensure that the contact compression spring is assembled. The positional relationship between the pin hole of the tie rod joint on the tie rod joint and the threaded hole at the static end of the arc extinguishing chamber in the circumferential direction of the arc extinguishing chamber meets the design and assembly requirements
