摘　　要：介绍了一种新型5自由度完全并联机床,该机床具有5个驱动分支和1个约束分支,可以实现三维移动和二维转动。根据该并联机床概念模型,对其总体布局、结构部件的参数化实体建模设计和装配体过程进行了研究。设计完成的虚拟样机参数化实体模型结构合理,外形逼真,可以直接用于工程分析和设计优化,为真实机床的研制提供了有效的手段。A novel five-degree of freedom fully parallel machine tool consisting of five actuating limbs and one passive constraint limb which can realized three-dimension and two-dimension move is proposed. The overall layout, parameterized solid modeling design of the structural components and their assembly process are studied. The designed parameterized solid model for the virtual prototype has reasonable structure and vivid shape and can be used directly for engineering analysis and design optimization, which provides effective means for manufacturing actual machine tool.
