Tooling for assembly and welding of roulette body and method of use

Abstract

The invention discloses an assembly welding tool for a wheel disc body and an application method. The assembly welding tool comprises a support seat, a left support upright, a right support upright, a stepping motor, a rolling bearing, a driving chuck, a short shaft, a long clamping jaw, a driven chuck, a long shaft, a bearing sleeve, a return shaft sleeve, a return pull disc, a push pull disc, a push shaft, a thrust bearing, an air cylinder, a working air chamber, a return air chamber and an air cylinder bracket, wherein the support seat comprises the left and right support uprights; the short shaft is in interference fit connection with the left support upright through the rolling bearing; the long shaft is in clearance fit connection with the bearing sleeve; the bearing sleeve is in interference fit connection with the right support column; and the long clamping jaw is embedded in the driving chuck and driven chuck. The technical scheme disclosed by the invention overcomes the deformation problem of free quenching of the wheel disc body, solves the cracking problem caused by pressure quenching and increases the product yield.

Description

technical field [0001] The invention relates to a tooling for assembly and welding for preventing quenching deformation of a wheel disc body and a use method thereof, and belongs to the technical field of heat treatment. Background technique [0002] The heat treatment of steel castings is a key process to improve the internal structure of the casting blank. As the key component of the train brake device, the disc body has extremely high requirements on its deformation and dynamic balance. However, since the shape of the cast steel roulette body is a thin-walled disc-shaped structure, and the heat dissipation ribs and mounting bosses are distributed on one side of the roulette body, which is an asymmetric structure, the roulette body is prone to warping and deformation during the free quenching process. , does not meet the size and balance requirements of the roulette body, so that the roulette body is scrapped. [0003] At present, in order to prevent the deformation of th...

AI Technical Summary

Problems solved by technology

During the quenching process of the roulette body, under the action of external pressure, although the deformation is well controlled, because the roulette body cannot shrink freely during the cooling process, the corners of the roulette body are concentrated in stress, resulting in cracks Defects, leading to an increase in the scrap rate of the roulette body
