細長軸的加工精度,如何來提高?
1.選擇合適(shi)的(de)(de)(de)(de)(de)(de)(de)電機(ji)軸裝(zhuang)夾方(fang)(fang)法(fa)如果(guo)采用(yong)(yong)傳統(tong)(tong)的(de)(de)(de)(de)(de)(de)(de)裝(zhuang)夾方(fang)(fang)式(shi),雖然定位比較準確(que),且(qie)能(neng)保證(zheng)同(tong)軸度(du)(du)(du)。但對(dui)于細(xi)(xi)長(chang)軸來(lai)講,則(ze)不(bu)(bu)太(tai)適(shi)合。因(yin)(yin)為它會(hui)使(shi)細(xi)(xi)長(chang)軸出現大(da)的(de)(de)(de)(de)(de)(de)(de)變(bian)形(xing),從(cong)而(er)產生振動,所以目(mu)(mu)前是采用(yong)(yong)一夾一頂這(zhe)種裝(zhuang)夾方(fang)(fang)式(shi),但使(shi)用(yong)(yong)時要注意應(ying)(ying)采用(yong)(yong)彈性(xing)(xing)活,在卡爪與細(xi)(xi)長(chang)軸之(zhi)間,可墊入一個開口鋼(gang)絲圈,以便消除過定位,從(cong)而(er)減少彎曲變(bian)形(xing)。2.合理控(kong)制切(qie)(qie)(qie)(qie)削(xue)(xue)用(yong)(yong)量(liang)(liang)切(qie)(qie)(qie)(qie)削(xue)(xue)用(yong)(yong)量(liang)(liang)合適(shi)與否(fou),會(hui)影(ying)響到細(xi)(xi)長(chang)軸的(de)(de)(de)(de)(de)(de)(de)變(bian)形(xing)程(cheng)(cheng)度(du)(du)(du),因(yin)(yin)此分幾個方(fang)(fang)面來(lai)考(kao)慮,為:切(qie)(qie)(qie)(qie)削(xue)(xue)深度(du)(du)(du):如果(guo)剛度(du)(du)(du)確(que)定了,那么(me)切(qie)(qie)(qie)(qie)削(xue)(xue)深度(du)(du)(du)越(yue)大(da),則(ze)細(xi)(xi)長(chang)軸的(de)(de)(de)(de)(de)(de)(de)受(shou)熱(re)變(bian)形(xing)程(cheng)(cheng)度(du)(du)(du)也越(yue)大(da),所以應(ying)(ying)盡量(liang)(liang)減少。進(jin)給(gei)量(liang)(liang):增大(da)進(jin)給(gei)量(liang)(liang),則(ze)會(hui)增加(jia)切(qie)(qie)(qie)(qie)削(xue)(xue)厚度(du)(du)(du)和(he)切(qie)(qie)(qie)(qie)削(xue)(xue)力度(du)(du)(du),但會(hui)使(shi)受(shou)力變(bian)形(xing)系(xi)數下(xia)降(jiang)。因(yin)(yin)此從(cong)提(ti)高(gao)切(qie)(qie)(qie)(qie)削(xue)(xue)效(xiao)率來(lai)看,增大(da)進(jin)給(gei)量(liang)(liang)是有(you)利的(de)(de)(de)(de)(de)(de)(de)。切(qie)(qie)(qie)(qie)削(xue)(xue)速(su)度(du)(du)(du):提(ti)高(gao)切(qie)(qie)(qie)(qie)削(xue)(xue)速(su)度(du)(du)(du),能(neng)降(jiang)低切(qie)(qie)(qie)(qie)削(xue)(xue)力,減小細(xi)(xi)長(chang)軸的(de)(de)(de)(de)(de)(de)(de)受(shou)力變(bian)形(xing)程(cheng)(cheng)度(du)(du)(du),但會(hui)帶來(lai)不(bu)(bu)好作用(yong)(yong),是會(hui)破壞切(qie)(qie)(qie)(qie)削(xue)(xue)的(de)(de)(de)(de)(de)(de)(de)平穩性(xing)(xing),因(yin)(yin)此不(bu)(bu)能(neng)盲目(mu)(mu)提(ti)高(gao),應(ying)(ying)控(kong)制在范圍內。 本公(gong)司有(you)著高(gao)水平的(de)(de)(de)(de)(de)(de)(de)加(jia)工系(xi)統(tong)(tong),憑著先進(jin)的(de)(de)(de)(de)(de)(de)(de)設備(bei),雄厚的(de)(de)(de)(de)(de)(de)(de)技(ji)術力量(liang)(liang),為客戶提(ti)供服務(wu)。多(duo)年來(lai)我公(gong)司以雄厚技(ji)術的(de)(de)(de)(de)(de)(de)(de)實力,優良的(de)(de)(de)(de)(de)(de)(de)售前、售后服務(wu)及良好的(de)(de)(de)(de)(de)(de)(de)信(xin)譽贏(ying)得了眾(zhong)多(duo)客戶的(de)(de)(de)(de)(de)(de)(de)廣泛好評。

對于生產用的電機電機軸在運行中發生軸肩與軸頸處斷裂,因為生產急需,這種情況能不能修復?
這種情況理論上是可以完成(cheng)的(de)(de),整(zheng)個過(guo)程中(zhong),焊(han)(han)(han)接(jie)(jie)和(he)焊(han)(han)(han)后熱處(chu)理是重要的(de)(de)環節。焊(han)(han)(han)前對原軸(zhou)及(ji)加工軸(zhou)頭仔(zi)細清(qing)理,嚴(yan)格清(qing)理會產(chan)生氫氣(qi)的(de)(de)油類等(deng)雜(za)質。焊(han)(han)(han)接(jie)(jie)可選用結857焊(han)(han)(han)條(tiao),直徑(jing)為(wei)3.2,焊(han)(han)(han)接(jie)(jie)前將(jiang)焊(han)(han)(han)條(tiao)故(gu)在(zai)(zai)熱源處(chu)烘(hong)干2h,隨用隨取(qu),清(qing)理焊(han)(han)(han)條(tiao)中(zhong)的(de)(de)水分。在(zai)(zai)直流電(dian)焊(han)(han)(han)機上采用反接(jie)(jie)法進行焊(han)(han)(han)接(jie)(jie),首先(xian)將(jiang)電(dian)機轉子軸(zhou)及(ji)加工軸(zhou)頭預熱300℃取(qu)出后吊到滾輪支架上,開始對稱交錯焊(han)(han)(han)樸,逐層添滿(man)U型(xing)坡口(kou)。焊(han)(han)(han)接(jie)(jie)時電(dian)流值可取(qu)90~100,慢速焊(han)(han)(han)防止轉子軸(zhou)過(guo)熱。焊(han)(han)(han)完后立即用氣(qi)割(ge)炬加熱焊(han)(han)(han)補位置100~120 mm以內區(qu)域,同(tong)時不斷轉動轉子軸(zhou),使之受熱均勻,避(bi)免變形。當(dang)加熱溫度達500~600℃時保溫1h,吊入300℃的(de)(de)烘(hong)爐一起冷卻至常(chang)溫。其目(mu)的(de)(de)是消除焊(han)(han)(han)接(jie)(jie)應力(li)、降低擴散氫的(de)(de)含(han)量,改善(shan)熱影(ying)響區(qu)的(de)(de)金相組織。
