摘要
建立 6 - PSS虚拟轴机床机构运动学模型 ,进行运动学分析 .为减少动连杆之间的结构干涉 ,且保证加工过程的 6个自由度 ,采用将刀具平台绕其自身轴线转动的自由度由安装在该平台上的刀具转动代替的方法 ,并在此基础上进行位移、速度分析 ,给出了解析表达式 .通过自行开发的仿真软件给出了驱动端运动规律曲线 .
A new form of 6 PSS virtual axis machine tool was established, and its kinematic modeling was proposed. To avoid the constructional interference between the ‘legs’ and to keep 6 freedoms during the processing, a method was adopted that requires the moving platform not to rotate around its own axis, and the lost freedom to give place to the rotation of tools. And on the basis of the modeling, forward and inverse velocities were analyzed. The data changing curves of the actuators' displacements and velocities were confirmed by a simulation software. A reasonable kinematic model can make the description of the manufacture process simple and intuitive
