Abstract：

A linkage rolling production line suitable for precision machining of micro-motor was designed including pressing device, transfer device and rolling device. The pressing device can prevent the workpiece from slipping through the design of locating ring, and it can automatically press the workpiece on the pressing station. Then, the transfer device can locate the workpiece and transfer it to the rolling station quickly, and the rolling device drives the rolling platform to turn the rolling head along the periphery of workpiece for rolling operation so as to ensure the consistency of rolling process. Furthermore, the mechanical structure and working principle for key part of production line were introduced in detail. Finally, the linkage rolling production line was used in the practice. Through the comparison of data before and after the modification of production line, the results show that the number of employees decreases from five persons to one person, the production rate reduces from 32 s/piece to 8 s/piece, and the defective rate drops significantly from 11‰ to 2‰, and each technical indicator is better.
