組(zu)合機(ji)床(chuang)一(yi)般用(yong)(yong)(yong)于加工(gong)(gong)箱體類(lei)或(huo)特(te)殊形(xing)狀的零件(jian)。組(zu)合機(ji)床(chuang)是以(yi)通用(yong)(yong)(yong)部件(jian)為(wei)(wei)基(ji)礎,配以(yi)按(an)工(gong)(gong)件(jian)特(te)定形(xing)狀和加工(gong)(gong)工(gong)(gong)藝設計(ji)的專用(yong)(yong)(yong)部件(jian)和夾具,組(zu)成的半自動或(huo)自動專用(yong)(yong)(yong)機(ji)床(chuang)。一(yi)般采用(yong)(yong)(yong)多軸、多刀、多工(gong)(gong)序、多面或(huo)多工(gong)(gong)位(wei)同時加工(gong)(gong)的方式。組(zu)合機(ji)床(chuang)通用(yong)(yong)(yong)部件(jian)按(an)照功能不同可分(fen)為(wei)(wei)以(yi)下五(wu)類(lei):

組(zu)合機床通(tong)用(yong)部(bu)件(jian)按功(gong)能可分為動力部(bu)件(jian)、支承部(bu)件(jian)、輸送(song)部(bu)件(jian)、控制(zhi)部(bu)件(jian)和(he)輔助(zhu)部(bu)件(jian)五類。

1.動力(li)部(bu)件(jian)是為組合機床(chuang)提(ti)供(gong)主(zhu)運動和進給(gei)運動的部(bu)件(jian)。主(zhu)要(yao)有動力(li)箱(xiang)、切削(xue)頭和動力(li)滑(hua)臺。

2.支承部(bu)件是用(yong)以安裝動力滑臺(tai)、帶有進給(gei)機構(gou)的切削頭或夾具等的部(bu)件,有側底座(zuo)(zuo)、中間底座(zuo)(zuo)、支架(jia)、可調支架(jia)、立柱和立柱底座(zuo)(zuo)等。

3.輸送部(bu)件是用以(yi)輸送工(gong)件或主(zhu)(zhu)軸箱至加工(gong)工(gong)位的部(bu)件,主(zhu)(zhu)要有(you)分度回(hui)轉工(gong)作(zuo)臺、環形分度回(hui)轉工(gong)作(zuo)臺、分度鼓輪和往復移動工(gong)作(zuo)臺等。

4.控制(zhi)部件是用以控制(zhi)機床的自動工作(zuo)循環的部件,有液壓站(zhan)、電氣柜和(he)操(cao)縱(zong)臺(tai)等。

5.輔助部件有(you)潤滑裝置、冷(leng)卻裝置和排(pai)屑(xie)裝置等。
