以自动焊接过程中的自动旋转工作台为研究背景。应用三维建模软件平台建立工作台中关键传动部位槽轮机构的虚拟样机,针对传统机构缺陷,结合运动仿真数据,提出新型槽轮机构的设计方法,并重新建立新型槽轮机构柔性体虚拟样机。通过有限元分析验证其设计的合理性,为高精度自动转台的设计制造和工程应用提供了理论依据。 In the automatic welding process automatic rotating table for the research background. A virtual prototype of the sheave mechanism of the key transmission parts in the workbench was set up by using the 3D modeling software platform. Aiming at the defects of the traditional mechanism and the kinematics simulation data, a new design method of the sheave mechanism was put forward and a new virtual body prototype of the sheave mechanism was reestablished. Through the finite element analysis to verify the rationality of its design, which provides a theoretical basis for the design and manufacture of high precision automatic turntable and engineering application.
