Abstract

The invention discloses a device for assembling a contact spring of a frame-type breaker, which consists of a bottom plate, a gear box, a pressing rod, a pressing rod bracket, a stop block and a positioning block, wherein the gear box, the stop block and the positioning block are all fixedly assembled on the bottom plate; the gear box has a rack which extends out of the gear box and a handle which operates sliding of the rack, the exposed end of the rack is step-shaped, and the step-shaped surface is inclined; the pressing rod bracket is fixed on the later surface of the gear box and positioned above the exposed end of the rack; the pressing rod is fixed on the middle part of the pressing rod bracket and can rotate around a fixed shaft; the pressing rod bracket has a '7'-shaped groove; the fixed shaft of the pressing shaft can slide along the '7'-shaped groove; and the lower end part of the pressing rod has an arc surface.

Description

technical field [0001] The invention relates to a frame circuit breaker contact spring assembly device in low-voltage switchgear equipment, which is applied to the frame circuit breaker assembly in the low-voltage switchgear. Background technique [0002] The growing prosperity of the domestic market economy has promoted the development of the power transmission and distribution equipment industry, which has greatly increased the demand for intelligent universal frame circuit breakers in power transmission and distribution equipment. At present, the assembly work of the frame circuit breaker still depends on manual operation to a large extent, especially the contact spring of the frame circuit breaker, which is very difficult to assemble without tooling assistance. The existing situation is to manually use a screwdriver to withstand the pressure spring, and after manually sending it into the mounting plate, one end of the spring is clamped to the boss. This method is time-c...
