畢業(yè)設(shè)計(jì)說明書（論文）中文摘要
車類機(jī)床主要用于加工各種回轉(zhuǎn)表面，如內(nèi)外圓柱表面、圓錐表面、成型回轉(zhuǎn)表面和回轉(zhuǎn)體的端面等，有些車床還能加工螺紋面。由于多數(shù)機(jī)器零件具有回轉(zhuǎn)表面，車床的通用性又較廣，因此在機(jī)器制造廠中，車床的應(yīng)用極為廣泛，在金屬切削床中所占的比重最大，約占機(jī)床總臺(tái)數(shù)的20%～35%。
作為主要的車削加工機(jī)床，CA6140機(jī)床廣泛的應(yīng)用于機(jī)械加工行業(yè)中，適用于車削內(nèi)外圓柱面，圓錐面及其它旋轉(zhuǎn)面，車削各種公制、英制、模數(shù)和徑節(jié)螺紋，并能進(jìn)行鉆孔，鉸孔和拉油槽等工作。床身寬于一般車床，具有較高的剛度，導(dǎo)軌面經(jīng)中頻淬火，經(jīng)久耐用。機(jī)床主軸孔徑大，操作靈便集中，溜板設(shè)有快移機(jī)構(gòu)。機(jī)床結(jié)構(gòu)剛度與傳動(dòng)剛度均比較高，功率利用率也比較高，適于強(qiáng)力高速切削。
臥式機(jī)床的加工對(duì)象，主要是軸類零件和直徑不太大的盤類零件，故采用臥式布局。其主要部件有：主軸箱、刀架、尾座、進(jìn)給箱、溜板箱以及床身。本設(shè)計(jì)主要針對(duì)CA6140機(jī)床的主軸箱進(jìn)行設(shè)計(jì)。機(jī)床主軸箱是一個(gè)比較復(fù)雜的傳動(dòng)部件。設(shè)計(jì)的內(nèi)容主要包括確定機(jī)床的主要參數(shù)，擬定傳動(dòng)方案和傳動(dòng)系統(tǒng)圖，計(jì)算和校核了主要零部件，并且利用專業(yè)制圖軟件進(jìn)行了零件的設(shè)計(jì)和處理。

Title Process Fork Parts to prepare and Milling
Fixture Design
Abstract
The lathe class machine tool mainly was used in to process each kind of rotation surface, like inside and outside periphery, the circular cone surface, take shape the rotation surface and the gyre end surface and so on, some lathes also can process whorl. Because the most machine part has the rotation surface, lathe versatility broader, therefore in machine shop, lathe application extremely widespread, accounts for the proportion in the metal cutting bed to be biggest, approximately composes the machine tool main station number 20% ~ 35%.
As the main turning processing machine tool, the CA6140 machine tool was widespread used in the machine-finishing profession, it is used in turning inside and outside the turning the round cylinder, taper and gyre, turning each kind of metric system, the British system, the modulus and the diameter festival thread, and can carry on the drill hole and pulls work and so on fuel tank. The lathe bed width to the common lathe , has a higher rigidity, the facade of the lead after middle frequency quenching, so it will be durable. The machine tool main axle aperture is big, the operation agile centralism, the apron is equipped with quickly moves the organization. machine tool structure rigidity and transmission rigidity quite high, the power use factor quite is also high, is suitable for the force high-speed cutting.
The horizontal-type machine tool processing object, mainly is the axis class components and the diameter not too big plate class components, therefore uses the horizontal-type layout. Its major component includes: headstock, tool slide, tailstock, feedbox, apron and bed. This design mainly aims at the headstock of the CA6140 machine tool .The headstock of machine tool is a quite complex transmission part. The design content mainly includes determines the machine tool’s main parameter, Draws up the transmission plan and the transmission scheme, Calculated and examined the main spare part，And used specialized charting software to carry on the components design and processing.
