摘　　要：为提高机油泵壳体加工的自动化程度,提升生产效率,需要对数控车床进行升级改造,增加C轴功能和动力刀架,并配套上下料机器人和自动料库。基于数字孪生技术,对自动上下料系统进行机电一体化设计。基于NX软件的MCD模块,建立了桁架式机器人的三维数字模型,并通过SIMIT软件实现该三维模型与控制程序的信号交换,并在此数字孪生模型的基础上,完成了上下料系统的机电一体化仿真和虚拟调试,缩短了新产品开发周期,降低了开发成本。In order to improve the automation and efficiency of oil pump shell processing,the C-axis and power tool holder were upgraded and the loading and unloading robot and automatic parts warehouse were equipped with a CNC lathe.Based on the digital twin technology,the mechanical and electrical integration design of the automatic loading and unloading system was provided.Three-dimensional digital model of a truss robot based on the MCD module of NX software was established,with which the signal exchange of control program was realized by SIMIT software.On the basis of the digital twin model,the mechatronics simulation and virtual commission of loading and unloading system were completed,the cycle of new product development was shortened and the cost was reduced.
