PAGE I 摘 要 组合机床是根据工件加工需要，以大量通用部件为基础，配以少量专用部件组成的一种高效专用机床。目前，组合机床主要用于平面加工和孔加工两类工序。其生产效率高，加工精度稳定，自动化程度高，降低人工劳动强度，因此广泛应用于到大批量生产场合。 本课题设计了变速箱体钻孔工位组合机床及左多轴箱。在设计中，依据被加工工件进行工艺分析；以及零件本身材料选取合适的切削用量，在充分计算动力参数基础上对标准通用部件做了选择，绘制了加工示意图，机床联系尺寸图以及生产率计算卡并且初定多轴箱的轮廓尺寸。 多轴箱是组合机床的重要专用部件，它是根据加工示意图确定工件加工孔的数量和位置，切削用量和主轴类型设计的传递各主轴运动的动力部件。其动力来自通用的动力箱，与动力箱一起安装于进给滑台，可完成钻孔等加工工序。本设计最终目的是通过所设计的组合机床左多轴箱实现多孔的一次加工完成，提高了工作效率并且减低人工劳动强度。 关键词：组合机床，三图一卡，多轴箱 ABSTRACT Combination machine tools is according to the work piece machining needs, on the basis of a large number of common components, with a small amount of dedicated components of an efficient special machine tool. At present, the modular machine tool is mainly used for surface machining and the machining process. Its high efficiency, stable machining precision, high degree of automation, reduce labor intensity of labor, therefore widely used in the mass production situation to. This topic design of the gearbox casing drilling location and left spindle box of modular machine tool. On the basis of processed work piece in the design, process analysis; Materials and parts itself to select suitable cutting dosage, on the basis of sufficient computing dynamic parameters of standard general parts made choice, mapped the process diagram, machine tool with the size chart and productivity calculation card early and dimensioning the contours of the spindle box. Spindle box of modular machine tool is important to special parts, it is according to the process diagram to determine the number and position of the work piece machining hole, cutting dosage and spindle type design of the main shaft power components of the movement. Its power from the general power box, together with the power box installed give sliding table, can complete the drilling and other processing operations. The purpose of this design is designed by left spindle box of modular machine tool of this design can achieve the porous once processing is complete, improve work efficiency and redu
