摘　　要：文中介绍了用于发动机生产线的主轴承盖螺栓全自动拧紧机。使用4个电动扳手自动拧紧螺栓,保证了生产节拍,提高了拧紧质量。拧紧的质量数据保存到数据库,并进行统计过程控制(Statistical Process Control,SPC)分析,对拧紧质量进行严格控制。此机床已在生产线上实际应用,运行稳定。Full automatic tightening machine for main bearing cap bolts in engine assembling line was introduced, four electric wrenches were used to carry out automatic tightening to ensure the production cycle and improve the quality of tightening. Quality data was saved to the database, and then Statistical Process Control （SPC） analysis was comp｜eted so that tightening quality was controlled strictly. This machine has been used in the engine-assembling line, and running in good condition.
