Universal breaker static contact head piece riveting clamp

Abstract

The invention discloses a universal breaker static contact head piece riveting clamp, and the universal breaker static contact head piece riveting clamp comprises a pedestal (11) and a limit support plate (9) arranged on the pedestal (11), the limit support plate (9) is opened with the grooves for holding the riveting piece run-on plate (7), outlet busbar (3) and angle bracket (6), a locating pin (18) is formed in the groove, the side of the limit support plate (9) is provided with a clamping press block (8); the clamp further comprises a limit frame (5) being parallel to the limit support plate (9), the limit frame (5) is provided with a locating plate (4) locating the angle bracket (6). According to the technique solution, the accuracy of the riveting position of the static contact head piece is guaranteed, the production efficiency is raised and the product quality is also guaranteed.

Description

technical field [0001] The invention relates to the technical field of riveting fixtures, in particular to a riveting fixture for static contact parts of a universal circuit breaker. Background technique [0002] The static contact parts of the universal circuit breaker are assembled by outgoing busbars, static contacts, angle brackets, and arc strike plates, and the brackets play the role of fixing the outgoing busbars on the bottom plate. When assembling, the angle bracket should be fixed on the outgoing busbar through hollow copper rivets first. The riveting of hollow rivets in the prior art is exactly to assemble each part on an inverted T-shaped plate, and then directly knocks a forming small punch to make it riveted. Due to the limited positioning of the T-shaped plate, it is difficult to determine the strength of manual knocking. Therefore, the static contact parts riveted by this traditional method often have the rivet bent or the bracket and the arc strike plate ar...

AI Technical Summary

Problems solved by technology

Due to the limited positioning of the T-shaped plate, it is difficult to determine the strength of manual knocking. Therefore, the static contact parts riveted by this traditional method often have the rivet bent or the bracket and the arc strike plate are not on the same plane, resulting in The rows are not on the same level, which will affect the contact performance of the fixed products after they are fixed in the low-voltage cabinet and connect the outgoing busbars, or cause poor contact when they are put into the drawer seat, which may cause the temperature rise of the universal circuit breaker products to be too high. affect product quality
