薄壁长轴套类零件双面加工专用机床设计

Design of Special Machine for Shaft Sleeve Parts Double Processing

针对薄壁长轴套类零件一般加工完一端后再调头加工另一端,生产效率低、且多次装夹不能有效保证两加工端同轴度和位置精度的特点,对原数控车床进行改进设计:保留机床原有的传动系统,床身尾端增加一套铣削动力头,设计专用夹具夹持工件,采用数控系统控制伺服电机驱动,实现工件的自动进给,研制专用组合刀具实现零件两端多工位的同时加工,使其成为一台适用于薄壁长轴套类零件两端铣削、镗孔、钻孔、内外倒角等加工工艺可同时加工的专用机床,具有提高加工精度、提高生产率、降低成本,且投资小、见效快、改装工作量少的效果。

In view of the shaft sleeve parts general processing end after processing head back on the other side,the production efficiency is low,and multiple setups can not be effectively guaranteed the two processing sides concentricity characteristics and location accuracy,improved design of the original CNC lathe： keep the original drive system,bed end increase a milling power head,design special fixture to clamp the workpiece,,the CNC system control servo motor drive,to realize the automatic feed,making it a general sleevethe process class parts at both ends of milling,boring,drilling,both inside and outside chamfer can be processed at the same time a dedicated machine. With the improvement of the machining accuracy,increase productivity,reduce cost,and small investment,quick effect,and the effect of the modification work less.
