摘要：

设计了一条适用于微特电机精密加工的联动辊轧生产线，具体包括：压装装置、输送装置和辊轧装置。压装装置通过定位环设计可防止工件滑动，并自动完成工件的压装作业；输送装置将工件快速定位，并转移至辊轧工位；辊轧装置驱动辊轧台带动辊轧头沿工件的周边转动进行辊轧作业，保证辊轧工艺的一致性。详细描述了生产线核心部分的机械结构和工作原理。该联动辊轧生产线已应用到实际生产中，通过生产线改造前后的数据对比发现，员工人数从5人减少至1人，生产节拍从32 s/件降低至8 s/件，次品率从11‰大幅度下降至2‰，各项技术指标较好。

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.
