细长腔体检测机器人设计研究

对现有人力不可达腔体的几种机器人检测方式进行比较,针对安装有精密零件的某航天器腔体设计了一台检测机器人XN-600-3.该机器人基于柱坐标系设计,视觉系统固定在一条细长机械臂末端,由两自由度关节驱动深入腔内进行检测。该机器人的大部分功能集中在机座内,即机械臂的全部驱动件移至机座内,悬臂部分负载最轻刚度最高,执行系统拥有最优的动态性能。试验证明该机器人具有长行程、高刚度、大回转角、小回转半径的优点,检测过程中视觉系统振幅最大为0.6 mm.通过机械臂末端的高精度摄像机捕获图像,该机器人可用于腔内装配尺寸或焊接质量等检测项目。

Design of Detection Robot for Slim Cavity

After comparing several methods to detect the cavity unreachable for human being by robots,a detection robot for a spacecraft cavity with the installation of high precision components named as XN-600-3 was designed based on the cylindrical coordinate.The visual system of the robot is mounted on the end of manipulator and gone deep into the cavity by the 2DoF joint driving.Most functions of the robot are set at the basement in which the drivers of manipulator are all mounted;with the light load and high rigi...
