Problems solved by technology

Shaft parts bear the role of supporting gears, pulleys, cams, connecting rods and other transmission parts in machinery to transmit torque. The processing of shaft parts has attracted more and more attention. One process is press-fitting. Usually, in order to achieve high installation stability of shaft parts, interference fit is used for assembly. Due to the different working occasions of shaft parts, the press-fitting process is likely to cause internal errors of shaft parts. Or improper assembly, it is easy to cause the problem of ring curling and press-fit misalignment during the press-fit process, which seriously affects the quality of the shaft sleeve

Abstract

The invention discloses a shaft part pressing fitting device, and belongs to the technical field of shaft sleeve part assembly equipment. The problem that circumferential coiling and pressing fittingdislocation are easily caused in the pressing fitting process in the prior art are solved. The shaft part pressing fitting device comprises an upper stamping part and a lower stamping part. The upperstamping part and the lower stamping part move relatively so as to achieve fitting of shaft parts. The upper stamping part comprises a first power assembly, an upper frame body, an upper pressing block assembly and a first adjusting disk assembly. The output end of the first power assembly is installed at the upper end of the upper frame body. The upper pressing block assembly is fixed on the lower portion of the upper frame body. The first adjusting disk assembly is arranged on a frame body at the lower end of the pressing block assembly. The lower stamping part comprises a second power assembly, a lower frame body, a lower pressing block assembly and a second adjusting disk assembly. The output end of the second power assembly is installed at the lower end of the lower frame body. By means of the shaft part pressing fitting device, circumferential rim coiling and unsmooth pressing fitting which are caused by slight dislocation in the pressing fitting process are avoided effectively,and the defective percentage is reduced effectively.

Description

technical field [0001] A shaft part pressing device belongs to the technical field of shaft sleeve part assembly equipment. Background technique [0002] Shaft parts are relatively common mechanical parts, which account for a large proportion of the products in the entire machinery industry and are widely used. According to different mechanism forms, shafts can be divided into stepped shafts, taper shafts, optical shafts, hollow shafts, crankshafts, camshafts, eccentric shafts, etc. Shaft parts bear the role of supporting gears, pulleys, cams, connecting rods and other transmission parts in machinery to transmit torque. The processing of shaft parts has attracted more and more attention. One process is press-fitting. Usually, in order to achieve high installation stability of shaft parts, interference fit is used for assembly. Due to the different working occasions of shaft parts, the press-fitting process is likely to cause internal errors of shaft parts. Or improper asse...
