Arc chute sheet assembling and pressing device for circuit breaker

Abstract

The invention relates to assembling equipment of a low-voltage circuit breaker, and particularly relates to an arc chute sheet assembling and pressing device for a circuit breaker, which is used for tightly pressing and assembling arc chute sheets arranged at intervals on a pair of flash barriers. The arc chute sheet assembling and pressing device comprises a base; a chute sheet base is arranged at the middle part of the base; vertical parallel clamping grooves are arranged on the chute sheet base; a distance between the clamping grooves is equal to a distance between the arc chute sheets to be assembled; the arc chute sheets to be assembled can be vertically placed in each clamping groove; the front and the back of the chute sheet base are respectively provided with a pressing board driven by an air cylinder; and a concave cavity matched with a flash barrier of a product to be assembled in width is arranged on the vertical face at the inner side of the pressing board. The arc chute sheet assembling and pressing device provided by the invention has the advantages of simple structure and convenience in operation; the tight pressing operation is carried out on the arc chute sheets and the flash barrier through a pair of the pressing boards driven by the air cylinder, so that the arc chute sheets and the flash barrier can be uniformly stressed, and the assembling consistence is good; and an assembling process is completed through one-step motion, so that the assembling efficiency can be improved, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to an assembly device for a low-voltage circuit breaker, in particular to a circuit breaker arc extinguishing grid assembling and pressing device for pressing and assembling spaced arc extinguishing grids on a pair of arc baffles. Background technique [0002] The arc extinguishing chamber of a low-voltage circuit breaker is usually composed of multiple arc extinguishing grids arranged at intervals and a pair of arc extinguishing plates connected on both sides of the arc extinguishing grid. The grids have slots with equal spacing, and at the same time, protrusions that interfere with the slots are provided on both sides of the arc extinguishing grid, so that the protrusions are pressed and connected with the slots. The assembly process is usually assembled by hand, with many procedures, complicated assembly, and high labor intensity. It needs to be clamped with a hammer on the front and back, and a large amount of dust is generate...

Problems solved by technology

The assembly process is usually assembled by hand, with many procedures, complicated assembly, and high labor intensity. It needs to be clamped with a hammer on the front and back, and a large amount of dust is generated to endanger the body; and due to large manual operation errors, product quality cannot be guaranteed. Resulting in unreliable overall product quality and low efficiency
