在车削加工中,有些零件要在同一道工序上进行打中心孔、钻孔、攻丝,套扣及车外圆、切槽、切断等。采用如图所示的组合式多工位刀架进行加工,效果较好。固定刀体可夹持在车床四方刀架上。旋转刀盘用来固定各种切削工具;弹簧用来定位时锁刀盘;定位销用于多工位定位;连接螺钉用来推出刀盘及换位;调整螺帽用来调整弹簧 In the turning process, some parts to be hit in the same process center hole, drilling, tapping, buckle and car outside the circle, grooving, cutting and so on. The use of the combination as shown in the multi-tool holder for processing, the better. Fixed knife body can be held in the lathe square turret. The rotary cutter is used to fix all kinds of cutting tools; the spring is used to lock the cutter when positioning; the positioning pin is used for multi-position positioning; the connecting screw is used to eject the cutter head and change position; the adjusting nut is used to adjust the spring
