這是什么原因?qū)е鲁霈F(xiàn)的問(wèn)題?我們對(duì)于出現(xiàn)的設(shè)備故障和問(wèn)題進(jìn)行了全面的排查分析:設(shè)備鉆工作臺(tái)中間孔時(shí)正常,當(dāng)鉆右側(cè)端面孔就會(huì)出現(xiàn)445號(hào)報(bào)警,并且兩個(gè)孔徑和鉆孔的深度、吃刀量和進(jìn)給量都相同,只不過(guò)是兩孔的間距相差了200mm。經(jīng)分析認(rèn)為:本加工中心是四軸聯(lián)動(dòng)的設(shè)備,工作臺(tái)B軸是可以回轉(zhuǎn)的,那么,在零件加工時(shí)會(huì)不會(huì)有轉(zhuǎn)動(dòng)的可能? 工作臺(tái)正常工作時(shí)是靠液壓電磁閥經(jīng)B軸下的鎖緊裝置夾緊是不轉(zhuǎn)動(dòng)的。為了證明判斷的準(zhǔn)確性,就將設(shè)備Z軸的導(dǎo)軌護(hù)罩面板拆開(kāi),找到B軸電動(dòng)機(jī)與B軸工作臺(tái)之間相聯(lián)接的皮帶,用手來(lái)回拉拽皮帶,發(fā)現(xiàn)工作臺(tái)也能隨之轉(zhuǎn)動(dòng),聯(lián)接在B軸電動(dòng)機(jī)上的編碼器也在轉(zhuǎn)動(dòng),這就是問(wèn)題的所在。我們還對(duì)設(shè)備操作人員進(jìn)行了零件加工過(guò)程裝卡方法和加工的材料進(jìn)行了詢問(wèn),了解到此零件的材料是40CrMoA合金鋼,材料鋼性好、硬度高,加工用的鉆頭刃具磨損,吃刀量偏大(為0.4mm/r),進(jìn)給速度正常。(http://www.diangon.com/版權(quán)所有)故障發(fā)生的原因,就相當(dāng)于用一個(gè)外在的作用力加在可以旋轉(zhuǎn)的B軸工作臺(tái)的右側(cè)面,形成了一個(gè)以B軸工作臺(tái)為中心的外力矩,雖然工作臺(tái)已被鎖緊,但由于工作臺(tái)鎖緊的力度小于加工鉆頭對(duì)被加工零件切削時(shí)產(chǎn)生的轉(zhuǎn)動(dòng)工作臺(tái)的轉(zhuǎn)矩,使得工作臺(tái)向右顫動(dòng),與B軸工作臺(tái)聯(lián)接的編碼器也在不停地抖動(dòng)而不穩(wěn)定,導(dǎo)致B軸工作臺(tái)出現(xiàn)445號(hào)報(bào)警。
