摘　　要：设计了一种高速多功能机头用在普通车床上,利用高速电主轴实现高速切削,电主轴的中心高度可以调节。在电主轴外锥上组装不同的刀具,在普通车床实现高速铣、钻、镗、磨功能。在电主轴上加装一个长杆套筒装置,可以对直盲孔和锥盲孔进行高速磨削,通过两相交轴锥齿改换刀具旋转位置,可对圆柱形轴的外圆和内孔轴向键槽进行铣削。有限元分析结果显示,工作频率、屈服强度满足材料要求,可以保证加工精度。A high-speed multi-function head used in ordinary lathe to achieve high-speed cutting with electric spindle is designed.The central height of the electric spindle can be adjusted.Assembling different cutting tools on the outer cone of electric spindle can realize multifunction of high-speed milling,drilling,boring and grinding in ordinary lathe.A long rod sleeve device is added to the main shaft,and the straight blind hole and tapered blind hole can be ground at high speed.By changing the rotating position,it is easy to mill the cylindrical shaft and inner hole axial key groove.Finite element analysis results show that the working frequency and yield strength meet the material requirements and can ensure the processing accuracy.
