Circuit breaker chassis clamping unit and circuit breaker chassis clamping tool

Abstract

The invention relates to a circuit breaker chassis clamping unit and a circuit breaker chassis clamping tool. The circuit breaker chassis clamping tool comprises a base and at least one working tablearranged on the base, wherein the circuit breaker chassis clamping unit is mounted on the working table and comprises a bottom plate; a stopping surface for stopping a circuit breaker chassis towardsthe rear direction and locating pins in location fit with kidney-shaped holes are arranged on the bottom plate; the circuit breaker chassis clamping unit further comprises a hold-down mechanism for compressing the circuit breaker chassis on a positioning structure; the locating pins can be inserted in the kidney-shaped holes in the circuit breaker chassis to position the circuit breaker chassis; and the hold-down mechanism compresses the circuit breaker chassis on the positioning structure to clamp the circuit breaker chassis. During the shot blasting operation process of the circuit breaker chassis, hands of a worker are liberated, so that the labor intensity of the worker is lowered, and the shot blasting treatment safety of the circuit breaker chassis is also improved.

Description

technical field [0001] The invention relates to a clamping unit and clamping tooling of a circuit breaker chassis. Background technique [0002] In order to improve the mechanical strength, wear resistance and corrosion resistance, the circuit breaker chassis needs to be shot blasted in the inner cavity during processing. Such as figure 1 As shown, the circuit breaker chassis 1 includes an upper L-shaped plate 11 and a lower L-shaped plate 12. The upper and lower L-shaped plates 11, 12 each have three vertical waist-shaped holes 14 in the length direction. The shaped plates 11 and 12 are opposed to each other and fixed together by connecting plates; the lower end of the circuit breaker chassis 1 has fixed connecting ears 13 extending outwards in the length direction for fixing. [0003] The circuit breaker chassis has a special structure, and there is no clamping tool designed for it on the market. At present, the shot blasting operation of the circuit breaker chassis oft...
