基于机械臂的空间水射流切割系统的设计与仿真

笔者以水射流切割机床机械臂为研究对象,基于SolidWorks软件建立了四轴空间水射流机床机械臂的模型,应用ADAMS软件的运动仿真功能,对4自由度机械臂的运动特性进行了仿真分析。仿真结果表明,应用四轴机械臂的空间水射流切割系统可完成空间复杂曲线运动,从而实现三维加工,如圆锥体、圆锥齿轮及螺纹等。通过增加摆动臂来解决水射流切割过程中的锥度补偿,提高了切割几何精度。

Design and simulation of space water jet cutting system based on manipulator

The manipulator of a water jet cutting machine was taken as the study object,the model of the manipulator of a water jet cutting machine with 4-axis space was established based on SolidWorks.The dynamic characteristics of the 4-DOF manipulator were simulated by using ADAMS.The simulation results showed that mapping of complicated space curves could be achieved by the designed 4-DOF manipulator,so as to complete 3D machining of such parts as cone,bevel gear and thread bolts etc.A swing arm was added to achieve the taper compensation during the water jet cutting process,thus the cutting geometric precision was enhanced.
