Abstract

The invention relates to a riveting clamp of an arc striking piece of a frame type circuit breaker. The riveting clamp comprises a static contact and the arc striking piece. The clamp comprises a power mechanism, a positioning and fixing mechanism and an upper punch. The power mechanism comprises an upper baffle, an upper fixing plate, a lower bottom plate, guide posts and springs. The positioningand fixing mechanism comprises limiting plates, a rear baffle, an arc striking piece pressing column, an arc striking piece cushion plate and an arc striking piece baffle. The upper punch is fixed below the upper fixing plate. The riveting clamp is small in size, ingenious in structure, attractive in appearance, easy to operate and low in cost.

Description

technical field [0001] The invention relates to the fixing technology of the arc leading piece of the frame circuit breaker, and specifically discloses a riveting fixture for the leading arc piece of the frame circuit breaker. Background technique [0002] Arc starter (such as figure 1 ) is an important part of electrical products, and its quality is directly related to the performance and quality of our products. Originally, the riveting of the arc striker of the KFW2 frame circuit breaker of the company required a large-tonnage punching machine for riveting. The upper mold and the lower mold were separated, the mold was large in size, it was extremely inconvenient to install parts, and the operation steps were cumbersome, which affected the efficiency of the product. Inaccurate mold adjustment will also affect product quality. In order to ensure product quality and better work efficiency, it is necessary to design fixtures that meet the company's requirements.
