摘　　要：介绍了一种发动机缸体曲轴孔加工组合刀具的设计,充分利用工件的内部空间,将曲轴孔加所需的镗刀、倒角刀、割槽刀与切止推面刀集成在1个刀杆上,以一把专用刀具,仅旋转工作台1次,即可完成缸体合箱前的曲轴孔加工的镗孔、倒角、粗切止推面、精切止推面与割轴瓦槽加工。使用该发动机缸体曲轴孔加工组合刀具进行加工时,大幅减少了换刀次数、工作台旋转次数和重新定位所需的空行程时间,加工效率提升2倍以上。This paper introduces the design of a combined tool for machining the crankshaft hole of engine cylinder blocks,which makes full use of the internal space of the workpiece and integrates the required boring,chamfering,slotting and thrust face tools into a tool bar.With the special tool,the worktable only needs to rotate once to complete the boring,chamfering,rough cutting of the thrust surface,fine cutting of thrust surface and the bearing bush groove cutting of crankshaft holes before the cylinder block is assembled.By using the combined tool for machining crankshaft holes of engine cylinder blocks,the idle travel time of tool change,workbench rotation and repositioning is greatly reduced,and the machining efficiency is increased by more than 2 times.
