Abstract: According to the phase accuracy and length precision of the miniature automobile drive shaft, combined with the characteristics of friction welding, a double spindle phase friction welding machine was designed. The machine can complete two welds at the same time to achieve the shaft pipe welding. Through the small batch welding experiment and the comprehensive evaluation of the welding parts, it is verified that the machine can realize the welding accuracy and stability of the shaft pipe, improve the production efficiency and reduce the production cost.
