A riveting jig for a sealed contactor with an elastic reed moving contact piece assembly

Abstract

The invention discloses a seal contactor riveting clamp for a moving contact chip component with an elastic reed. The seal contactor riveting clamp comprises a bottom plate, a pedestal fixedly connected above the bottom plate, and an upper punch matched with a lower punch, wherein a lower punch holder is installed above the pedestal through a connecting screw; the middle part of the lower punch holder is fixedly connected with the lower punch; the upper end of the upper punch is sheathed with a supporting arm; the top end of the upper punch is fixedly connected with a spherical nut; the lower end of the spherical nut is sheathed with return springs; a rubber block is fixedly connected onto the lower punch holder; a punching riveting pretightening mechanism is arranged between the rubber block and the upper punch. According to the seal contactor riveting clamp, as one punching riveting pretightening mechanism is arranged between the upper punch and the lower punch, the moving contact chip component with the elastic reed can be pretightened before punching riveting without the need of being manually pretightened; therefore the labor intensity of manpower can be decreased greatly; moreover, the riveting precision is effectively improved; meanwhile, the threat of potential safety hazards can also be lowered, so that the occupational accidents are reduced.

Description

technical field [0001] The invention relates to a riveting fixture, in particular to a riveting fixture for a sealed contactor with an elastic reed moving contact piece assembly Background technique [0002] One process in the assembly process of the sealed contactor is the riveting of the moving contact piece assembly with elastic reeds, such as figure 1 , 2 As shown in and 3, the structure of the movable contact piece assembly with elastic reeds is a new type of structure, which has never appeared in traditional contactors. When the product is assembled, since the elastic reed is a bow-shaped shrapnel, when it is in a free state, the top is in contact with the bottom surface of the moving contact piece assembly, and the bottom will push the bush and the gasket downward, and the bottom of the threaded bush is used for riveting. The segment cannot be exposed from the bottom surface of the gasket, so it cannot be riveted by the traditional method, because when the movable c...
