With the development of the technology, the application of the press mounting mode is more and more mature, the press mounting mode is a revolutionary sign of a forming equipment assembly production line, and the press mounting mode has wide development space.

At present, the plug press-fitting mechanism adopted by some gearbox manufacturers adopts the following mode: the mechanism is driven by a servo press, and press fitting is carried out by utilizing a press head arranged at the front end of the servo press. However, the gearbox plug press-mounting mechanism has the defects that: due to the existence of factors such as the deviation of the installation size of equipment, the deviation exists between the depth of the plug pressed into the reduction gearbox and a theoretical value.

If the press-fitting force is insufficient or the press-fitting depth does not reach the theoretical depth in the press-fitting process, the parts need to be disassembled and then pressed again, so that the press-fitting quality and the production efficiency are influenced, the shaft diameter, the shell and other parts are possibly damaged, and the parts are scrapped more seriously. Therefore, for the production of automobile gearbox parts, it is very important to adopt a reasonable and effective press fitting technology, and the advanced and reliable press fitting technology not only can provide the production efficiency, but also can improve the product quality.
