[0002] The wheel axle seat is a key core component of a traveling working device of a road roller. Its function is to connect the drive axle chain and the wheel rim for fixing. Because it carries the driving force of the whole machine, it adopts a relatively tight interference fit and is equipped with a flat key for installation. At present, the assembly field of the wheel axle seat mostly adopts electromagnetic heating to a certain temperature, and then the wheel axle is aligned and placed in the heated wheel axle seat. After completion, due to its own high temperature, it is impossible to proceed to the next process of assembly, resulting in a 4-hour waiting time and extremely low efficiency. In this process, in order to improve production efficiency and reduce the manufacturing cycle, the process of assembling the wheel axle seat assembly without affecting its internal quality is considered. However, the biggest disadvantage of the press-fitting method is that it involves flat key alignment inside, which cannot meet the requirements of full press-in to the design size, cannot meet the requirements of this design structure, and the process brings about high rework time and rework costs, as well as quality problems such as scratches on parts.
