摘　　要：针对等离子割炬初始高度定位方式存在的一些问题,设计了两种定位方式:一是利用钢板导电性进行接触定位,在电路中利用共模电感等元件来增强抗干扰性能;二是采用限位开关进行初始定位,割炬调高体采用扭轮摩擦传动机构,将限位开关合理地安装在该调高体内,简化定位机构结构。对比分析了所设计的两种定位方式与目前国内常用的几种定位方式,结果表明,限位开关定位方式更具经济性和实用性。With regard to some problem of initial height positioning on plasma cutting torch,this paper has introduced two ways of initial height positioning.One way is to use conductivity of armor plate to make location,the designed circuit has used the common- mode inductor and others to enhance anti-jamming performance.Another way is to use the limit switch for positioning,and lifting device of cutting torch has used the twist-roller frictional drive.Meanwhile,the limit switch is integrated into the lifting device,making this positioning mechanism designed to be simple.Finally,the paper have done a comparative analysis between two ways referred to the paper and the current domestic positioning ways ,and have concluded that such limit switch positioning mode have been more economical and practical.
