Abstract：

To solve the long-standing problems of high requirements of shot peening and difficulty in processing methods for frame parts, a new shot peening processing method was formulated for the typical frame parts. By analyzing the digital model of part, the outer surface of each part in the digital model of part was numbered and quantified according to the type, and the surface of different types was shot peened according to different angles and shot peening times. Afterwards, the feeding path of nozzle was designed, and combined with local surface protection, the equipment, fixtures, auxiliary tools and process auxiliary materials were selected. Furthermore, combined with processing procedures, the part protection plan was designed. Through the optimization of process, the entire surface of part could be shot peened at a suitable angle, the surface coverage rate is 100% which meet the requirements of the drawing, and the production efficiency is greatly improved at the same time, which provide a feasible and effective reference for subsequent production and processing of such parts and even similar parts.
