Framework oil seal automatic pressing machine

Abstract

The invention discloses a framework oil seal automatic pressing machine, and belongs to the technical field of framework oil seal pressing. According to the framework oil seal automatic pressing machine, the problems that in the prior art, the working efficiency is low, and the pressing quality is poor in consistency are solved. The framework oil seal automatic pressing machine comprises a rack; the rack is provided with a pressing station quick-changing device, an executing mechanism, a guiding compressing device and an axial positioning device which are mutually matched; the pressing stationquick-changing device is fixed to the rack through a linear guiding rail II; the pressing station quick-changing device comprises a transverse fixed air cylinder I and a transverse movable air cylinder II; and a piston rod of the transverse fixed air cylinder I is connected with a fixing plate through a first connecting plate, the transverse movable air cylinder II is fixed to the fixing plate, apiston rod of the transverse movable air cylinder II is connected with a second connecting plate, and the fixing plate can slide along the linear guiding rail II. The framework oil seal automatic pressing machine is mainly used for pressing operation of a framework oil seal and a sealing cover.

Description

Technical field [0001] The invention relates to an automatic frame oil seal press-fitting machine, which belongs to the technical field of frame oil seal press-fitting. Background technique [0002] The main drive sealing cover of the loader drive axle and the two skeleton oil packages must be assembled in advance, and then assembled to the main drive assembly as a whole for sealing. At present, the skeleton oil seal and the sealing cover are assembled using pressure plates and copper rods. The operator's labor intensity is high, the assembly efficiency is low, and the on-site knocking noise is loud, causing certain damage to the operator's hearing; the skeleton of the double oil seal structure The installation of the oil seal in the sealing cover is in a suspended state. The pressure plate is not evenly stressed during manual knock assembly, which makes it difficult to ensure the vertical pressing of the oil seal, and there are multiple shocks and strong vibrations during the as...

AI Technical Summary

Problems solved by technology

At present, the parts of the frame oil seal and the sealing cover are assembled by tapping with a pressure plate and a copper rod. The labor intensity of the operator is high, the assembly efficiency is low, and the on-site tapping noise is large, which will cause certain damage to the operator's hearing; the frame with double oil seal structure The installation of the oil seal in the sealing cover is in a suspended state. Due to the uneven force on the pressure plate during manual knocking and assembly, it is difficult to ensure the vertical pressing of the oil seal. In addition, there are multiple shocks and strong vibrations during the assembly process, and the assembled oil seal is also damaged. Dislocation due to vibration will cause the oil seal to tilt after assembly, which will cause oil seal failure and oil leakage

In recent years, some skeleton oil seal press-fitting devices have appeared in the industry. For example, Chinese patent 201420845677.0 discloses a skeleton oil seal pneumatic press-fitting machine. Most of these press-fitting devices use air cylinders or air jack cylinders for press-fitting, and the pressure fluctuation of the press-fitting is relatively large. large, resulting in fluctuations in press-fitting quality, and most press-fitting devices can only press-fit a single type of oil seal, and cannot guarantee the assembly position of various oil seals. When the type is switched, the press-fitting plate needs to be replaced, and the work efficiency is not significantly improved.
