Fixtures for crimping springs of bow plate assemblies

Abstract

The invention discloses a tool clamp for a bow plate component crimping spring. The tool clamp comprises a base and a pressure head, wherein a plurality of pressure plates are connected with the lower end of the pressure head; the base is composed of a locating seat and a mounting seat at the upper end of the locating seat; a locating through hole is arranged in the middle of the locating seat; a mounting through hole is arranged in the middle of the mounting seat; a locating shaft matched with the locating through hole is arranged inside the locating through hole; the upper end of the locating shaft extends out of the mounting through hole; a guide shaft is sleeved on the locating shaft; a mounting shaft is sleeved at the lower end of a guide shaft on the locating shaft; the lower end of the mounting shaft resists against the locating seat; the diameter of the guide shaft orderly increases from top to bottom; and guide grooves matched with the pressure plates are arranged at the lower part of the guide shaft along a longitudinal manner. The tool clamp for the bow plate component crimping spring is simple in structure, easy to achieve, and low in manufacturing cost, and the pressure head is driven to press downwards by a press, so as to drive the pressure plate to vertically press the spring, so that the spring is buckled into the tip of the bow plate component, the operation is convenient, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to a tooling fixture for a bow-shaped plate assembly crimping spring. Background technique [0002] A circuit breaker is generally composed of a contact system, an arc extinguishing system, an operating mechanism, a trip unit, and a housing. Among them, the contact system is one of the most important components of the circuit breaker. The contact system generally includes a fixed fixed contact and a moving contact that moves relative to the static contact. At present, a moving contact commonly used in the market includes a bow-shaped plate assembly composed of four bow-shaped plates and springs crimped at both ends. Due to the large spring force, manual crimping is difficult to achieve. Therefore, most Some tooling fixtures are used to cooperate with a press to complete the process. However, the existing tooling fixtures used for crimping springs of moving contacts of circuit breakers have comp...
