眾所(suo)周知，高速(su)加工技術(shu)發展迅速(su)，而(er)推動這種發展趨勢的正(zheng)是數(shu)控車(che)床，如何(he)合理利用好數(shu)控車(che)床的各項性能和(he)維護好車(che)床的精度，就顯得至關重要，現(xian)在就結合中(zhong)山(shan)市諾信智能裝備有(you)限(xian)公(gong)司技術(shu)工程人員(yuan)的工作經驗，說說車(che)床在電(dian)源方面需(xu)要注意(yi)的一些細節和(he)常識，希望會對大家有(you)幫助。

       電源是維持系(xi)(xi)統(tong)(tong)(tong)正常工(gong)(gong)作(zuo)的(de)(de)能(neng)(neng)源支(zhi)持部分(fen)，它失(shi)(shi)效或故(gu)障的(de)(de)直接(jie)結果(guo)是造成系(xi)(xi)統(tong)(tong)(tong)的(de)(de)停機或毀壞整個系(xi)(xi)統(tong)(tong)(tong)。另外，數控系(xi)(xi)統(tong)(tong)(tong)部分(fen)運(yun)行數據(ju)，設定(ding)數據(ju)以及加工(gong)(gong)程序(xu)等一般存(cun)貯在RAM存(cun)貯器內，系(xi)(xi)統(tong)(tong)(tong)斷電后(hou)，靠電源的(de)(de)后(hou)備蓄電池(chi)或鋰電池(chi)來保持。因(yin)而，停機時間比(bi)較長，拔插(cha)電源或存(cun)貯器都可(ke)能(neng)(neng)造成數據(ju)丟失(shi)(shi)，使系(xi)(xi)統(tong)(tong)(tong)不能(neng)(neng)運(yun)行。

       控制電源是(shi)(shi)數控系統硬(ying)件的重要組成部(bu)分(fen)，也是(shi)(shi)在維修(xiu)中常常出(chu)現問(wen)題的部(bu)分(fen)。小(xiao)數控車床廠家(jia)的車床電源系統有(you)直(zhi)流與交流兩(liang)個部(bu)分(fen)。

       （1）直流電(dian)(dian)源作為控制用多(duo)(duo)為開(kai)關穩壓(ya)電(dian)(dian)源，有(you)＋5V、＋24V、±15V等電(dian)(dian)壓(ya)，各設備的電(dian)(dian)壓(ya)情況不(bu)盡相(xiang)同，例如CRT上供電(dian)(dian)電(dian)(dian)壓(ya)有(you)的是(shi)24V，有(you)的是(shi)交流110V或(huo)220V。所(suo)以，數(shu)控車床廠家盡可(ke)(ke)能地看好各端子供電(dian)(dian)電(dian)(dian)壓(ya)的要求。電(dian)(dian)源非常重要，一旦(dan)出錯會造成不(bu)可(ke)(ke)彌(mi)補(bu)的損失。還有(you)是(shi)對伺服(fu)供電(dian)(dian)的直流電(dian)(dian)壓(ya)，它大多(duo)(duo)數(shu)是(shi)經伺服(fu)變壓(ya)器(qi)及整流裝置所(suo)獲(huo)得的。

       （2）交(jiao)流(liu)電(dian)源(yuan)是(shi)控(kong)制系統提供能(neng)源(yuan)的(de)(de)器(qi)件(jian)，也是(shi)給伺服驅(qu)動提供能(neng)源(yuan)的(de)(de)器(qi)件(jian)。交(jiao)流(liu)電(dian)源(yuan)上也有(you)各種(zhong)保護(hu)及(ji)切換(huan)裝(zhuang)置；有(you)短路、隔離及(ji)失壓保護(hu)。這個交(jiao)流(liu)電(dian)源(yuan)向伺服系統供電(dian)時，一定要注意有(you)晶閘管器(qi)件(jian)的(de)(de)裝(zhuang)置的(de)(de)供電(dian)相(xiang)序(xu)，一旦(dan)程序(xu)接錯，有(you)晶閘管器(qi)件(jian)就失去了同步(bu)的(de)(de)關系，造成故障。

       由于數(shu)控裝置中(zhong)有些信息要(yao)(yao)在車床(chuang)斷電(dian)(dian)(dian)情況下進行(xing)保持，因此有一(yi)(yi)部(bu)分(fen)RAM區(qu)用電(dian)(dian)(dian)池(chi)(chi)來進行(xing)數(shu)據(ju)保持，這(zhe)些電(dian)(dian)(dian)池(chi)(chi)多數(shu)是鋰電(dian)(dian)(dian)池(chi)(chi)，壽(shou)命長，但電(dian)(dian)(dian)量(liang)小。數(shu)控車床(chuang)廠家這(zhe)部(bu)分(fen)電(dian)(dian)(dian)池(chi)(chi)也可用普通(tong)電(dian)(dian)(dian)池(chi)(chi)經二極管降壓(ya)達到(dao)所需電(dian)(dian)(dian)壓(ya)值來代(dai)替，但一(yi)(yi)定要(yao)(yao)注意壽(shou)命。電(dian)(dian)(dian)池(chi)(chi)必須在通(tong)電(dian)(dian)(dian)情況下進行(xing)更換，否則數(shu)據(ju)就(jiu)會丟失，這(zhe)一(yi)(yi)點(dian)與常規習慣不(bu)同，更換時要(yao)(yao)注意不(bu)產生短路(lu)現象。
