中文摘要
内容 动力箱，各种工艺切削头和动力滑台是组合机床完成切削主运动或进给运动的动力部件。其中还能同时完成切削主运动和进给运动的动力头。而只能完成进给运动的动力部件称为滑台。固定在动力箱上的主轴箱是用来布置切削主轴，并把动力箱输出轴的旋转运动传递给各主轴的切削刀具，由于各主轴的位置与具体被加工零件有关，因此主轴箱必须根据被加工零件设计，不能制造成完全通用部件，但其中很多零件（例如：主轴，中间轴，齿轮和箱体等）是通用的。床身，侧底座，中间底座等是组合机床的支承部件，起着机床的基础骨架作用。组合机床的刚度和部件之间的精度保持性，主要是由这些部件保证。移动的或回转的工作台是多工位组合机床的主要部件之一，它起着转换工位和输送工位的作用，因此它们的直线运动和回转运动的重复定位精度直接影响组合机床的加工精度。除了上述主要部件之外，组合机床还有各种控制部件，主要是指挥机床按顺序动作，以保证机床按规定的程序进行工作。

Chinese abstract
Content The power box, each kind of craft cutting head and the power slipway is the aggregate machine-tool completes cuts the host movement or enters for the movement power part. Also can simultaneously complete cuts the host movement and enters for the movement power head. But only can complete is called for the movement power part slipway. Fixes the headstock is uses for in the power box to arrange the cutting main axle, and transmits the power box output shaft rotary motion for various main axles cutting tool, because various main axles position with makes concrete is processed the components related, therefore the headstock must act according to is processed the components design, cannot make creates the completely general part, but very many components (for example: The main axle, the intermediate shaft, the gear and the box body and so on) is general.The lathe bed, leans the foundation, the middle foundation and so on is the aggregate machine-tool supporting part, is playing the engine bed foundation skeleton role. Between the aggregate machine-tool rigidity and the part precision retentivity, mainly is guaranteed by these parts. Motion or the rotation work table is one of multiplex position aggregate machine-tool major components, it plays is transforming the location and transports the location the role, therefore their translation and gyroscopic motion repetition pointing accuracy direct influence aggregate machine-tool processing precision.Besides the above major component, the aggregate machine-tool also has each kind of control portion, mainly is directs the engine bed according to the smooth movement, guaranteed the engine bed carries on the work according to the stipulation procedure.
Key word Aggregate machine-tool, power box, slipway, headstock, foundation
