多功能模块化串并联机床结构的研究

在分析当前机床技术发展的趋势的基础上，提出了一种新型模块化并联机床结构，机床主运动的实现采用并联机构，工件的进给运动由串联机构实现。研究了机床主运动模块平面二自由度机构的运动特性，给出了机构运动学正反解。机床采用模块化结构设计，据加工需要，可方便快捷地组合设计不同自由度的机床；运动机构串并联相结合，既具有结构简单，刚度重量比大，响应速度快的特点，又具有工作空间较大的特点。

Study on Multi-function Modularization structure of Serial and Parallel Machine Tool

Analyzing the development tendency of the present machine tool technology,we presented a new modularization structure of serial and parallel machine tool,which adopted parallel mechanism to the main movement and serial mechanism to the workpiece feeding movement.furthermore,the kinematics character of a 2 DOF planar structure was studied,positive and negative solution of machine kinematics was given.The modularization design method can rapidly scheme out different DOF of machine tools.On the other hand,the combination of serial and parallel mechanism to machine tool can simplify its structure,improve its rigidity and response speed,and possess larger workspace.
