一臺數控機床一次出現故障,負載(zai)門關(guan)(guan)不(bu)上,自(zi)動(dong)加工不(bu)能(neng)進行,而且*顯示。這個負載(zai)門是由氣缸來(lai)(lai)完成開關(guan)(guan)的(de)(de),關(guan)(guan)閉負載(zai)門是PLC輸出Q2.0控制(zhi)電磁閥Y2.0來(lai)(lai)實現的(de)(de)。用(yong)NC系(xi)統(tong)的(de)(de)PC功(gong)能(neng)檢查PLC
Q2.0的狀態,其(qi)狀態為1,但(dan)電(dian)磁閥卻(que)沒有得電(dian)。原(yuan)來PLC輸出Q2.0通過中間繼(ji)電(dian)器(qi)(qi)控制(zhi)電(dian)磁閥Y2.0,中間繼(ji)電(dian)器(qi)(qi)損壞(huai)引(yin)起這(zhe)個故障,更換新的繼(ji)電(dian)器(qi)(qi),故障被排除(chu)。
例六、一(yi)臺數控(kong)機床,工(gong)作臺不(bu)(bu)旋轉,NC系統沒有顯示故障報警(jing)。根(gen)(gen)據(ju)工(gong)作臺的動(dong)作原理,工(gong)作臺旋轉第(di)一(yi)步(bu)(bu)(bu)應(ying)將工(gong)作臺氣動(dong)浮起(qi),利用機外編程器,跟(gen)蹤PLC梯圖的動(dong)態變化,發(fa)現(xian)PLC這個信號并未(wei)發(fa)出,根(gen)(gen)據(ju)這個線索繼續(xu)查(cha)看,最后發(fa)現(xian)反映二(er)、三工(gong)位(wei)分度頭(tou)起(qi)始(shi)位(wei)置(zhi)檢測開關I9.7、I10.6動(dong)作不(bu)(bu)同步(bu)(bu)(bu),導致了工(gong)作臺不(bu)(bu)旋轉。進一(yi)步(bu)(bu)(bu)確認為三工(gong)位(wei)分度頭(tou)產生機械錯(cuo)位(wei),調整機械裝(zhuang)置(zhi),使其與二(er)工(gong)位(wei)同步(bu)(bu)(bu),這樣使故障消除。
發現問(wen)題是(shi)(shi)解決(jue)(jue)問(wen)題的第一(yi)(yi)(yi)步,而且是(shi)(shi)最重要(yao)的一(yi)(yi)(yi)步。特別是(shi)(shi)對(dui)數(shu)控(kong)機(ji)床的外(wai)(wai)部故障,有時診斷(duan)過程(cheng)比(bi)較復雜,一(yi)(yi)(yi)旦(dan)發現問(wen)題所在,解決(jue)(jue)起來(lai)比(bi)較輕(qing)松。對(dui)外(wai)(wai)部故障的診斷(duan),我們總結出兩(liang)點(dian)經驗(yan),首(shou)先(xian)應熟練(lian)掌握機(ji)床的工作原理和動(dong)作順序。其(qi)次要(yao)熟練(lian)運用(yong)廠(chang)方提供的PLC梯圖(tu),利用(yong)NC系(xi)統(tong)的狀態顯示功能或(huo)用(yong)機(ji)外(wai)(wai)編程(cheng)器監測(ce)PLC的運行(xing)狀態,根(gen)據梯圖(tu)的鏈鎖關系(xi),確定(ding)故障點(dian),只要(yao)做到以上兩(liang)點(dian),一(yi)(yi)(yi)般(ban)數(shu)控(kong)機(ji)床的外(wai)(wai)部故障,都(dou)會(hui)被(bei)及時排除。
