对电机总装关键工艺——有绕组铁心入壳压装技术——进行分析和研究。在智能制造前提下，对定子入壳压装工艺进行改进。设计了数字化卧式定子机壳自动压装设备及工装，并由PLC系统集中协调控制，可实现机壳定子的自动定位、卧式装夹与压装、压装参数的采集/反馈/监控、与数字化车间运行管理系统交互等功能。实际应用表明：采用改进工艺后，定子入壳压装效率提高40%，产品不良率降低85.7%，人工减少30%。

Pressing technology of winding core into shell, as a key process of motor assembly, is analyzed. In order to achieve intelligent manufacturing, the process of pressing the stator into the shell is improved, and the digitalized horizontal automatic pressing equipment for stator casing and the matching tooling, which are controlled and coordinated by PLC system, are designed. This pressing equipment can realize the functions of automatic positioning, horizontal clamping and pressing, collecting/feedback/monitoring of pressing parameters, interaction with the digital workshop operation management system, etc. Practical application results show that the pressing efficiency is increased by 40%, the product defective rate is decreased by 85.7%, and the manpower is reduced by 30%.
