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.

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-fit. Background technique [0002] The main transmission sealing cover of the loader drive axle and the two skeleton oil seals must be assembled in advance before being assembled, and then assembled to the main transmission assembly as a whole to play a sealing role. 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 ...
