Abstract
The invention discloses a riveting device for a switch shell and a coil assembly of an automobile starter electromagnetic switch. The riveting device comprises an upper die and a lower die. The upper die comprises an upper die plate, a compressing piece and four tapered wedge cutters. The four tapered wedge cutters are vertically and evenly distributed on the lower portion of the upper die plate. The compressing piece is located in the center, among the four tapered wedge cutters, of the upper die. The lower die comprises a lower die plate, a lower die positioning block and four evenly distributed horizontal stamping knife assemblies. The lower die positioning block is fixedly connected to the center of the upper portion of the lower die plate. Each horizontal stamping knife assembly comprises a butting pillar, a stamping knife holder and a horizontal stamping knife, wherein a tapered wedge cutter descending space is formed between the butting pillar and the stamping knife holder, the opposite end of a puncher pin of the horizontal stamping knife is provided with a horizontal stamping knife slope matched with the corresponding tapered wedge cutter on the upper die. By the adoption of the structure, the riveting and assembling device for the switch shell and the coil assembly of the automobile starter electromagnetic switch can guarantee that the assembly accuracy and the size meet technical requirements, improve production efficiency and reduce the manufacturing cost.
