[Abstract]:Axle is the key part of locomotive moving parts, and its performance is directly related to the driving safety of the vehicle. The application of surface rolling strengthening technology in axle production can greatly improve the fatigue strength of axle. Therefore, the surface rolling strengthening technology, equipment and related technology of axle have become one of the indispensable key technologies in the current locomotive manufacturing industry. In order to realize the surface rolling strengthening of railway locomotive, rolling stock, subway and other axle parts, the research team has developed a new type of axles numerical control rolling machine for railway locomotives, rolling stock, subway and so on. In this paper, according to the overall requirements of the CNC rolling machine tool, the design of the axle clamping system of the machine tool is completed, and the mechanical analysis and calculation of the key parts of the system are carried out. Then the movement of the clamping system of the machine tool is analyzed by the finite element method. Static characteristics, finally completed the installation of the equipment, debugging and preliminary rolling test. The results show that the clamping system of the machine tool can realize the automatic clamping of the axle, the orientation of the axial center and the uniform rotation. The strength and stiffness of the whole structure meet the design requirements. The new CNC rolling machine has the advantages of simple structure, neat appearance, high production efficiency, high dimension precision and good surface quality. All its performance indexes have reached the intended target.
