Abstract

The invention relates to a manufacturing device of low voltage circuit-breakers for power transmission and distribution, in particular to a riveting fixture for low voltage circuit-breaker arc extinguishing chambers. The fixture comprises a jig base. The middle of the jig base is provided with a drawer groove. A drawer block can be inserted into and positioned in the drawer groove. The drawer block is provided with longitudinally-arranged grating slots. A plurality of arc extinguishing grating pieces to be fitted can be inserted into and positioned in the grating slots. Two sides of the drawer block are provided with sliders capable of moving transversely. The inner side of each slider is provided with a pointed riveting head. The upper portion of the outer end of each slider is provided with an upward wedge face. An upper jig capable of moving up and down vertically is disposed above the jig base. Two sides of the upper jig are provided with downward wedge faces fitting the upward wedge faces of the sliders. The riveting fixture is simple in structure and capable of acting reliably; the arc extinguishing grating pieces are positioned through the drawer block, positioning is accurate, riveting quality is good, and machining efficiency is improved.

Description

technical field [0001] The invention relates to a manufacturing equipment of a low-voltage circuit breaker for power transmission and distribution, in particular to a riveting jig for an arc extinguishing chamber of a low-voltage circuit breaker. Background technique [0002] The structure of the low-voltage circuit breaker in the power transmission and distribution system usually consists of multiple arc extinguishing grids arranged at intervals and a pair of side plates on both sides of the arc extinguishing grid. The side plates are used to connect each arc extinguishing grid. One. The connection between the side plate and the arc extinguishing grid adopts riveting, and the specific structure is to set bumps on both sides of each arc extinguishing grid, and at the same time set riveting holes matching the bumps on the side plate. During the manufacturing process, the two side plates are first matched and connected with the bumps of each arc extinguishing grid, and then t...
