摘　　要：在数控工作台应用分析的基础上,提出虚拟轴数控工作台的设计要求,构造一种新型3平移1转动的4自由度并联机器人机构,并将其作为虚拟轴工作台本体机构。简介机构各支链的连杆、运动副组成,确定和选择工作台样机的各运动副部件。在CAXA实体设计软件中创建样机的三维CAD模型。该并联机构的设计、样机模型及理论研究结果为虚拟轴数控工作台的开发打下了基础。Based on the analysis of application of numerical control （NC） worktable, the design requirements for a virtual axis NC worktable are presented. A new three-translation and one-rotation 4-DOF parallel robot mechanism is constructed according to the design requirements and it acts as the primary mechanism of the virtual axis worktable. Each branch of the mechanism is composed of links and couplings. The parts of kinematic pairs of the worktable prototype are confirmed and chosen. 3-D CAD models are built in CAXA solid design software. The design, prototype model and theoretical research results of the parallel mechanism lay a foundation for the development of the virtual axis NC worktable.
