Assembly process of electromagnetic switch of automobile starter

Abstract

The invention discloses an assembly process of an electromagnetic switch of an automobile starter. The assembly process comprises the steps of 1) integrally riveting a coil block and a switch housing, 2) mounting a movable core mechanism assembly and a fixed core mechanism assembly, 3) mounting a bakelite end cover, and 4) welding an inner-layer starting end and an outer-layer starting end, welding an inner-layer tail end, wherein in the step 1), the coil block is integrally riveted with the switch housing on a riveting device which is composed of an upper mold and a lower mold; the upper mold comprises an upper plate, a hold-down part and four inclined-wedge knives; the lower mold comprises a lower plate, a lower mold positioning block, and four equally distributed transverse stamping knife components; the upper plate is connected with a hydraulic machine; the upper mold is lowered down, and the four transverse stamping knives are capable of completing the stamping of riveting points simultaneously. The assembly process of the electromagnetic switch of the automobile starter is capable of guaranteeing that the accuracy and the dimension of assembly conform to the technical requirements, improving the percent of pass of assembly, improving the production efficiency and reducing the manufacturing cost.

Description

technical field [0001] The invention relates to an automobile starter, in particular to an assembly process for an electromagnetic switch of an automobile starter. Background technique [0002] The electromagnetic switch of automobile starter includes bakelite end cover, coil assembly, switch housing, moving core machine assembly and static core machine assembly. The switch housing and coil assembly are an integrated structure. The coil assembly includes coil cover plate, coil and skeleton The switch housing has a cylindrical main body, the coil is placed in the cylinder of the switch housing, the coil is supported by the frame, and the inner end of the coil is provided with a coil cover. [0003] The assembly process of the electromagnetic switch of the automobile starter is as follows: 1. Riveting the coil assembly and the switch housing as one; 2. Installing the moving core machine assembly and the static core machine assembly; The end of the layer and the end of the out...
