摘　　要：连接套是非煤矿山凿岩钎具的一个重要组成部分,连接套的螺纹加工质量直接关系到连接套的使用寿命。旋风铣是与普通车床配套的高速铣削螺纹装置,因其加工时的速度快、精度高、表面粗糙度好等诸多优点,已受到业内越来越多的重视。介绍了在普通车床上进行的溜板、滚珠丝杠、挂轮箱、刀杆及铣轴箱等机械方面的改造方法,同时简要介绍了西门子S7-200系列PLC为控制主件的包含西门子MM440变频器、步进电机主电机等电气元件的控制电路设计。最终实现了普通车床到专用于凿岩连接套的波形内螺纹加工的旋风铣床的改造,很好地解决了凿岩连接套的波形内螺纹加工问题。The coupling sleeve is an important part of the rock drill tools for non coal mine.The thread processing quality of the coupling sleeve is directly related to the service life of the coupling sleeve.The whirlwind milling is a high speed milling screw device matching with the common lathe.Because of its high velocity,high precision,good surface roughness and so on,it has been paid more and more attention in the industry. The modification methods of the slide plate,the ball screw,the wheel box,the cutter bar and the milling axle box on the ordinary lathe are introduced. At the same time,a brief introduction to the control circuit design of SIEMENS S7-200 series PLC for controlling the main components,including SIEMENS MM440 inverter,stepper motor,main motor and other electrical components,is also presented.Finally,the modification of the ordinary lathe to the whirlwind milling machine with inner thread for rock drilling coupling sleeve corrugated is realized,which solves the problem of the inner thread machining of drilling coupling sleeve.
