Tapered roller bearing press-fitting mechanism, press-fitting method and press-fitting mistake-proofing method thereof

Abstract

The invention discloses a tapered roller bearing press-fitting mechanism, a press-fitting method and a press-fitting mistake-proofing method thereof. The tapered roller bearing press-fitting mechanismcomprises a fixing frame, the top and the bottom of the fixing frame are provided with a stamping part and a press-fitting part which are press-fitted with each other respectively, the stamping part,a middle shaft to be pressed and the press-fitting part are in coaxial abutting connection at the pressing moment; the stamping part comprises a driving part, a stamping clamp and a centering cone which are connected in sequence, the two sides of the driving part are connected with two guide shafts respectively, the two guide shafts are arranged on the fixing frame in a mirror symmetry mode, thestamping clamp, the centering cone and the guide shafts move up and down along with the driving part relative to the press-fitting part; the press-fitting part comprises a guide clamp, and the guide clamp is arranged at the bottom of the fixing frame. Compared with the prior art, according to the actual situation of the middle shaft to be pressed, the middle shaft is pressed through the stamping part to enable the middle shaft to complete press fitting of the size tapered roller bearing at one time, through the matching of the stamping part and the press-fitting part, so that the size taperedroller bearing can be stably and accurately installed on the middle shaft.

Description

technical field [0001] The invention relates to a press-fitting tool, which belongs to the field of automobile manufacturing, in particular to a tapered roller bearing press-fitting mechanism. Background technique [0002] The 6AT transmission is composed of more than 200 parts, large and small, mainly consisting of housing components, torque converter housing components, oil pump assembly, intermediate support assembly, C1 clutch and rear planetary carrier assembly, C2 / C3 Clutch and front planetary carrier assembly, hydraulic torque converter, valve body assembly, differential and planetary carrier assembly, intermediate shaft, intermediate support shaft gear and other parts, among which the role of shaft gear in the transmission is not necessary Undoubtedly, the shaft and gear parts are all rolling parts, and it is a big problem to press the bearing on the shaft and gear parts; in the practical application of 6AT gearbox, the shaft and gear parts occupy the core position, ...

AI Technical Summary

Problems solved by technology

[0003] The tapered roller bearing and the intermediate shaft belong to an interference fit. In the face of the demand for large production, ordinary mechanisms cannot meet the requirements.
