摘　　要：设计了一种基于等离子电弧电压检测的割炬高度控制系统。该系统通过中断方式采样电弧电压,并结合机器人离线编程技术实时控制等离子割炬高度,确保在等离子划线切割过程中割炬与工件间的距离始终保持在一定范围之内,保证了划线和切割质量。将该系统应用于船用型材划线切割机器人系统中,提高了划线和切割精度,且切口平整。A plasma torch＇ s height control system which is based on plasma arc voltage measuring is introduced. It samples the plasma arc voltage with interrupt mode and real-timely controls the height of plasma torch based on offline program, which makes the distance between plasma torch and workpiece keep within a certain limit and then ensures the quality of lining and cutting. This system is applied to the profile lining and cutting robot system, which improves the precision of hning and cutting and makes the kerf smooth.
