摘要：为了满足S195型柴油机气缸盖年生产量60000件的需要，现设计一多工位组合机床，来完成气缸盖导管孔Ф17H7以及进排气座圈孔Ф46H8、Ф40H8的加工。按照以下几个步骤渐次展开本次设计：首先通过分析待加工件的特征，初定以上各个孔的加工工艺（钻、扩、铰和镗、铰）；其次是考虑精度以及粗糙度要求，选定切削用量；而后绘制组合机床三图一卡，通过查阅相关手册确定导向类型、选定接杆和卡头的规格，根据切削参数选择动力部件的规格并进而确定机床的工作行程。最终在满足生产要求的前提下，算得机床的生产负荷率η=72%，满足设计要求；紧接着设计多轴箱，根据各输出轴的转速确定传动比、传动齿轮齿数等参数；最后校核多轴箱内零件的强度，满足要求，可认为多轴箱设计合理。综上，本次设计的组合机床基本满足生产要求，设计工作取得成功。

Title Drill, boring and reaming machine tool design
Abstract：In order to meet the S195 diesel engine cylinder head annual production capacity of 60,000 pieces of the need to design a multi-station combination of machine tools to complete the cylinder head guide hole Ф17H7 and into the exhaust seat hole Ф46H8, Ф40H8 processing.
According to the following steps to gradually expand the design: First, by analyzing the characteristics of the workpiece to be processed, the initial processing of the above holes (drilling, expansion, hinge and boring, hinge); followed by consideration of precision and roughness requirements, According to the cutting parameters to select the specifications of the power components and then determine the work of the machine trip. The machine can be used to determine the size of the machine. And finally meet the production requirements of the premise, calculate the machine production load rate η = 72%, to meet the design requirements; followed by the design of multi-axis box, according to the output shaft speed to determine the transmission ratio, transmission gear teeth and other parameters; Multi-axle box parts strength, to meet the requirements, that multi-axle box design is reasonable.
In summary, the design of the basic combination of machine tools to meet the production requirements, design work to be successful.
