搖臂鉆床是一種金屬切削類機床適合于中小型零件的加工，是一種通用型銑床。經過設備不同的刀具既能完成鉆床所具有的工件鉆孔、擴孔操作，又能完成各種工件的平面、斜面的加工。這種設備的運用規模較為廣泛。搖臂鉆床的首要用處(chu)就(jiu)要體現在(zai)機械加工與機械制造。

搖臂(bei)鉆(zhan)床適(shi)用(yong)(yong)(yong)(yong)于中(zhong)、大型金屬零件(jian)上鉆(zhan)孔(kong)、擴孔(kong)、鉸孔(kong)、锪平面、及攻螺紋，液(ye)壓(ya)(ya)型搖臂(bei)鉆(zhan)床首要功(gong)用(yong)(yong)(yong)(yong)動(dong)(dong)(dong)(dong)(dong)作(zuo)完(wan)(wan)結的(de)手(shou)柄、按鈕等操(cao)(cao)(cao)作(zuo)部(bu)件(jian)會合(he)在主(zhu)(zhu)(zhu)軸(zhou)(zhou)箱上,搖臂(bei)鉆(zhan)運(yun)動(dong)(dong)(dong)(dong)(dong)部(bu)件(jian)較(jiao)多，為了(le)簡化傳(chuan)動(dong)(dong)(dong)(dong)(dong)設備(bei)，選(xuan)用(yong)(yong)(yong)(yong)多臺(tai)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)拖動(dong)(dong)(dong)(dong)(dong)。例如Z3040型搖臂(bei)鉆(zhan)床選(xuan)用(yong)(yong)(yong)(yong)4臺(tai)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)拖動(dong)(dong)(dong)(dong)(dong)，他們別離(li)是主(zhu)(zhu)(zhu)軸(zhou)(zhou)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)，搖臂(bei)升降電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)，液(ye)壓(ya)(ya)泵(beng)(beng)(beng)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)和冷卻泵(beng)(beng)(beng)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)，這(zhe)些電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)都選(xuan)用(yong)(yong)(yong)(yong)直(zhi)接啟動(dong)(dong)(dong)(dong)(dong)辦法。為了(le)習慣多種辦法的(de)加工要求，設備(bei)主(zhu)(zhu)(zhu)軸(zhou)(zhou)的(de)旋轉及進(jin)給運(yun)動(dong)(dong)(dong)(dong)(dong)有(you)較(jiao)大的(de)調速(su)(su)規模，一般狀況下多由機(ji)(ji)械(xie)變速(su)(su)組(zu)(zu)織(zhi)(zhi)完(wan)(wan)成。主(zhu)(zhu)(zhu)軸(zhou)(zhou)變速(su)(su)組(zu)(zu)織(zhi)(zhi)與(yu)進(jin)給變速(su)(su)組(zu)(zu)織(zhi)(zhi)均(jun)裝在主(zhu)(zhu)(zhu)軸(zhou)(zhou)箱內(nei)。 主(zhu)(zhu)(zhu)運(yun)動(dong)(dong)(dong)(dong)(dong)和進(jin)給運(yun)動(dong)(dong)(dong)(dong)(dong)均(jun)為主(zhu)(zhu)(zhu)軸(zhou)(zhou)的(de)運(yun)動(dong)(dong)(dong)(dong)(dong)，為此這(zhe)兩項運(yun)動(dong)(dong)(dong)(dong)(dong)有(you)一臺(tai)主(zhu)(zhu)(zhu)軸(zhou)(zhou)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)拖動(dong)(dong)(dong)(dong)(dong)，別離(li)經主(zhu)(zhu)(zhu)軸(zhou)(zhou)傳(chuan)動(dong)(dong)(dong)(dong)(dong)組(zu)(zu)織(zhi)(zhi)，進(jin)給傳(chuan)動(dong)(dong)(dong)(dong)(dong)組(zu)(zu)織(zhi)(zhi)完(wan)(wan)成主(zhu)(zhu)(zhu)軸(zhou)(zhou)的(de)旋轉和進(jin)給。內(nei)外主(zhu)(zhu)(zhu)軸(zhou)(zhou)的(de)夾緊(jin)與(yu)放松、主(zhu)(zhu)(zhu)軸(zhou)(zhou)與(yu)搖臂(bei)的(de)夾緊(jin)與(yu)放松可用(yong)(yong)(yong)(yong)機(ji)(ji)械(xie)操(cao)(cao)(cao)作(zuo)、電(dian)(dian)氣(qi)—機(ji)(ji)械(xie)設備(bei)，電(dian)(dian)氣(qi)—液(ye)壓(ya)(ya)或(huo)電(dian)(dian)氣(qi)—液(ye)壓(ya)(ya)—機(ji)(ji)械(xie)等操(cao)(cao)(cao)控(kong)辦法完(wan)(wan)成。若選(xuan)用(yong)(yong)(yong)(yong)液(ye)壓(ya)(ya)設備(bei)，則備(bei)有(you)液(ye)壓(ya)(ya)泵(beng)(beng)(beng)電(dian)(dian)機(ji)(ji)，拖動(dong)(dong)(dong)(dong)(dong)液(ye)壓(ya)(ya)泵(beng)(beng)(beng)供(gong)給壓(ya)(ya)力油來(lai)完(wan)(wan)成，液(ye)壓(ya)(ya)泵(beng)(beng)(beng)電(dian)(dian)機(ji)(ji)要求能正(zheng)反(fan)向旋轉，并根據要求選(xuan)用(yong)(yong)(yong)(yong)點動(dong)(dong)(dong)(dong)(dong)操(cao)(cao)(cao)控(kong)。
