摘      要

車床是機(jī)械制造中使用最廣泛的一類機(jī)床，主要用于加工各種回轉(zhuǎn)表面（如：內(nèi)外圓柱面、圓錐面、環(huán)槽、回轉(zhuǎn)體成型面等）和回轉(zhuǎn)體的端面，有些車床還能加工螺紋。在一般機(jī)器制造廠中，由于大多數(shù)零件都具有回轉(zhuǎn)表面，同時(shí)車床本身的萬(wàn)能性強(qiáng)，使用的刀具簡(jiǎn)單，所以車床在金屬切削機(jī)床中所占的比重較大。而在所有的車床類機(jī)床中，以臥式車床的應(yīng)用最為廣泛。因?yàn)榕P式車床的工藝范圍相當(dāng)廣泛，可以車削內(nèi)外圓柱面、圓錐面、環(huán)形槽、回轉(zhuǎn)體成型面，車削端面和各種常用的公制、英制、模數(shù)制、徑節(jié)制螺紋，還可以進(jìn)行鉆中心孔、鉆孔、擴(kuò)孔、鉸孔、攻螺紋、套螺紋和滾花等工作。本文闡述了一個(gè)12級(jí)轉(zhuǎn)速的C6132臥式車床主軸箱的設(shè)計(jì)過(guò)程，主軸箱用以支撐主軸并使之旋轉(zhuǎn)。主軸為空心結(jié)構(gòu)，其前端外錐面安裝三爪卡盤等附件來(lái)夾持工件，前端內(nèi)錐面用來(lái)安裝頂尖，細(xì)長(zhǎng)孔可穿入長(zhǎng)棒料，箱內(nèi)只有一級(jí)變速，其主軸變速機(jī)構(gòu)安放在遠(yuǎn)離主軸的單獨(dú)變速箱中，以減小變速箱中的傳動(dòng)件產(chǎn)生的振動(dòng)和熱量對(duì)主軸的影響。

ABSTRACT

The abstract lathe is in the machine manufacture uses a most widespread kind of engine bed, mainly uses in processing each kind of rotation surface (for example: In the outer annulus cylinder, the circular conical surface, the ring groove, the solid of revolution formation surface and so on) and the solid of revolution end surface, some lathes also can process the thread. In common machine shop, because the majority components all have the rotation surface, simultaneously lathe itself multi-purpose is strong, the use cutting tool is simple, therefore the lathe occupies in the metal-cutting machine tool the proportion is big. But in all lathe class engine bed, is most widespread by the horizontal lathe application. Because the horizontal lathe craft scope is quite widespread, may in the turning the outer annulus cylinder, the circular conical surface, the ring channel, the solid of revolution formation surface, the turning end surface and each kind of commonly used metric system, the British system, the mold notational system, the pitch system thread, but also may carry on drills the center bore, the drill hole, the broaching, reams, work and so on tapping, wrap thread and knurling. This article elaborated a 12 level of rotational speed C6132 horizontal lathe headstock design process, the headstock uses to support the main axle and to cause it revolving. The main axle is the hollow structure, appendices and so on its front end male cone installment three support on both sides the work piece, front end in the conical surface uses for to install the apex, the tall and slender hole may penetrate the long good material, in the box only then the level speed change, its main axle gearshift mechanism imposition in is far away the main axle in the independent gear box, reduces the vibration and the quantity of heat which in the gear box the biography moving parts produce to the main axle the influence.
