中文摘要
內(nèi)容 動力箱，各種工藝切削頭和動力滑臺是組合機床完成切削主運動或進給運動的動力部件。其中還能同時完成切削主運動和進給運動的動力頭。而只能完成進給運動的動力部件稱為滑臺。固定在動力箱上的主軸箱是用來布置切削主軸，并把動力箱輸出軸的旋轉(zhuǎn)運動傳遞給各主軸的切削刀具，由于各主軸的位置與具體被加工零件有關(guān)，因此主軸箱必須根據(jù)被加工零件設(shè)計，不能制造成完全通用部件，但其中很多零件（例如：主軸，中間軸，齒輪和箱體等）是通用的。床身，側(cè)底座，中間底座等是組合機床的支承部件，起著機床的基礎(chǔ)骨架作用。組合機床的剛度和部件之間的精度保持性，主要是由這些部件保證。移動的或回轉(zhuǎn)的工作臺是多工位組合機床的主要部件之一，它起著轉(zhuǎn)換工位和輸送工位的作用，因此它們的直線運動和回轉(zhuǎn)運動的重復定位精度直接影響組合機床的加工精度。除了上述主要部件之外，組合機床還有各種控制部件，主要是指揮機床按順序動作，以保證機床按規(guī)定的程序進行工作。
關(guān)鍵詞： 組合機床，動力箱，滑臺，主軸箱，底座



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
