先进商用车差速器壳自动线的实践

Practice of Automatic Line for Advanced Commercial Vehicle Differential Case

随着商用车差速器壳产品的升级换代,零件精度不断提高,智能化生产的要求也不断更新,某公司换代差速器壳采用了国内首条集成化的加工、检测、清洗全自动化的生产线。介绍该生产线的具体案例,采用集成化的工艺方案,选用高效加工设备及工装,配合智能补偿反馈系统、在线统计过程控制(Statistical Prozess Contro,SPC)、自动防错等智能化技术,实现了高品质、高效率、低成本的精益生产。

With the upgrading of commercial vehicle differential case products,the accuracy of parts is continuously improved,and the requirements of intelligent production are constantly updated.The first full-automatic production line with integrated functions including differential cases machining,testing and cleaning in China was introduced in a Chinese transmission producer.This paper introduced specific cases of the production line,which adopted the integrated process scheme,selected efficient processing equipment and tooling,and in cooperation with intelligent technologies such as compensation feedback system,online Statistical Prozess Contro(SPC)control and automatic error proofing to realize lean production with high quality,high efficiency and low cost.
