Arc extinction equipment for circuit breaker sheet assembling hold down gag
Technical field
The present invention relates to a kind of assembly equipment of low-voltage circuit breaker, specifically a kind of being used for will be arranged at intervals with the arc extinction equipment for circuit breaker sheet assembling hold down gag of arc extinguishing grid pieces compression fit on a pair flash barrier.
Background technology
Usually be made up of spaced multiple arc extinguishing grid pieces and a pair flash barrier being connected to arc extinguishing grid pieces both sides at the arc-chutes of low-voltage circuit breaker, its connected mode is that interval arranges the draw-in groove suitable with arc extinguishing grid pieces spacing on flash barrier, arrange and draw-in groove interference fit projection in arc extinguishing grid pieces both sides simultaneously, projection is connected with draw-in groove compression fit.The usual hand assembled of its assembling process, operation is more, and assembling is complicated, and labour intensity is comparatively large, needs to knock clamping with hammer positive and negative, produces a large amount of dust harzard health; And due to manual operation error comparatively large, product quality can not get ensureing, causes integral product quality unreliable, and inefficiency.
Summary of the invention
Technical problem to be solved by this invention is, provides the arc extinction equipment for circuit breaker sheet assembling that a kind of structure is simple, easy to operate, efficiency of assembling is high, assembly quality is good hold down gag.
Arc extinction equipment for circuit breaker sheet assembling hold down gag of the present invention comprises a base, a grid seat is provided with in the middle part of base, grid seat has parallel longitudinal draw-in groove, and draw-in groove spacing is suitable with arc extinguishing grid pieces spacing to be assembled, and arc extinguishing grid pieces to be assembled can vertically be placed in each draw-in groove; Respectively be provided with one before and after grid seat by the pressing plate of air cylinder driven, the vertical plane inside pressing plate have a cavity matched with the flash barrier width of product to be assembled.
The sidewall of cavity is provided with several ball holes, in ball hole, is mounted with spring and ball, enable a part for ball elastic telescopic in cavity side walls.
Structure of the present invention is simple, easy to operate; Carry out compression by the pressing plate of air cylinder driven to arc extinguishing grid pieces and flash barrier by a pair to operate, its uniform force, assembling uniformity is good; It completes assembling by one-off, improves efficiency of assembling, reduces labour intensity.

Detailed description of the invention
As shown in the figure, this arc extinction equipment for circuit breaker sheet assembling hold down gag comprises a base 1, a grid seat 2 is provided with in the middle part of base, grid seat has parallel longitudinal draw-in groove 3, the spacing of draw-in groove spacing and arc extinguishing grid pieces P1 to be assembled is suitable, and arc extinguishing grid pieces to be assembled can vertically be placed in each draw-in groove 3; A pressing plate driven by cylinder 45 is respectively provided with before and after grid seat 2, vertical plane inside pressing plate 5 has a cavity 6 matched with the flash barrier P2 width of product to be assembled, the sidewall of cavity 6 is provided with several ball holes 7, be mounted with spring 8 and ball 9 in ball hole, enable a part for ball 9 elastic telescopic in cavity side walls.
The course of work of the present invention is as follows:
First each arc extinguishing grid pieces P1 is arranged on the draw-in groove 3 of grid seat 2 before compression fit, two panels flash barrier P2 is placed in the cavity 6 of former and later two pressing plates 5 respectively, due to ball 9 pairs of flash barrier edges elasticity pressure holding, enable flash barrier be fixed in cavity 6; Then, start cylinder and pressing plate 5 is pressed to arc extinguishing grid pieces both sides, flash barrier is crimped with arc extinguishing grid pieces and is integrated.
