Abstract

The invention relates to the field of jigs, in particular to a shot-blasting reinforcing jig. The shot-blasting reinforcing jig comprises a fixed base, a bottom connecting seat, a center fixing rod, aprotective cylinder sleeve, a connecting sleeve, an inner gland, an outer gland and an elastic device, the bottom connecting seat is arranged in the base, the bottom end of the center fixing rod is fixedly connected to the bottom connecting seat, the center fixing rod penetrates through the protective cylinder sleeve, the top end of the center fixing rod is fixedly connected into the connecting sleeve, the connecting sleeve penetrates through the inner gland, the connecting sleeve is fixedly connected with the outer gland, and the elastic device is arranged between the outer gland and the inner gland. According to the shot-blasting reinforcing jig, a rotating machine table is connected with the fixed base, the protective cylinder sleeve sleeves a synchronizer gear hub, and the synchronizer gear hub is clamped on the jig through the elastic glands. Thus shot-blasting reinforcing can be conducted on multiple synchronizer gear hubs on the jig simultaneously by rotating the jig, and the shot-blasting efficiency is improved.

Description

technical field [0001] The invention relates to the field of jigs, in particular to jigs for shot peening strengthening. Background technique [0002] Shot peening is a surface strengthening process widely used in factories, that is, a cold working process that bombards the surface of the workpiece with pellets and implants residual compressive stress to improve the fatigue strength of the workpiece. It is widely used to improve the mechanical strength of parts, as well as wear resistance, fatigue resistance and corrosion resistance. However, when the synchronizer gear hub of the automobile gearbox is shot peened, since there is no special jig for supporting positioning, the shot peening efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is: In order to solve the technical problems described in the background technology, the present invention provides a shot peening strengthening fixture, which is connected to...
