摘　　要：针对大尺寸工件难以采用传统圆度仪进行测量,研发了一套适合大型圆筒类零件的轮廓误差在线测量系统。本测量系统采用单片机+PC控制,以2根同步转动的托辊带动被测圆筒旋转,通过非接触式传感器获取被测工件的表面轮廓测量数据。基于轮廓定位式圆度误差算法,求出工件表面各等分点的轮廓误差值并绘制曲线图。理论分析和实验结果表明本系统能够实现大型圆筒的在线测量,具有良好的应用前景。An online measurement system is developed for the contour error measurement of large cylindrical parts.The system is controlled by single-chip microprocessor+PC.The rotation of the measured parts is driven by two synchronously rotating rollers,and their surface profile is measured through a non-contact sensor.The companion algorithms for evaluating the roundness error are programmed to extract the contour error value of each equinox of the workpiece surface,and the contour error curve is plotted.Theoretical analyses and experimental results show that the system is feasible to carry out the online measurements of large cylinders,and may be of value for various engineering applications.
