詳情 / Introduction
  
一、本機探傷原理描述
  ZK－XII型(xing)(xing)大型(xing)(xing)齒輪(lun)磁(ci)軛式旋轉磁(ci)場熒光(guang)磁(ci)粉(fen)探傷機(ji)(ji)，是(shi)針(zhen)對大型(xing)(xing)帶(dai)軸(zhou)齒輪(lun)磁(ci)粉(fen)探傷的(de)(de)機(ji)(ji)電分(fen)立式、多組合(he)結構(gou)專(zhuan)用探傷設備。它(ta)的(de)(de)磁(ci)化原理和機(ji)(ji)械結構(gou)是(shi)根據大型(xing)(xing)帶(dai)軸(zhou)齒輪(lun)具體形狀而設計。適用于檢測(ce)齒輪(lun)工件因鍛造、鑄造、熱處理、冷加工所造成的(de)(de)細微裂紋(wen)，在不破(po)壞其外觀(guan)質(zhi)量和金相(xiang)組織的(de)(de)情況下(xia)，作直觀(guan)顯(xian)示檢查(cha)。
  由于(yu)大(da)(da)型帶(dai)軸(zhou)齒(chi)(chi)(chi)輪(lun)其(qi)(qi)齒(chi)(chi)(chi)輪(lun)直(zhi)徑大(da)(da)于(yu)2000mm,中(zhong)心(xin)無孔(kong)，所以不適(shi)用(yong)中(zhong)心(xin)孔(kong)穿棒通(tong)電(dian)(dian)即(ji)中(zhong)心(xin)導電(dian)(dian)法(fa)探傷(shang)，另外(wai)雖然(ran)有(you)齒(chi)(chi)(chi)輪(lun)軸(zhou)，但(dan)齒(chi)(chi)(chi)輪(lun)直(zhi)徑太大(da)(da)，如果采(cai)(cai)用(yong)齒(chi)(chi)(chi)輪(lun)軸(zhou)夾緊通(tong)電(dian)(dian)，則通(tong)電(dian)(dian)電(dian)(dian)流(liu)(liu)需大(da)(da)于(yu)20000A，而且(qie)齒(chi)(chi)(chi)尖(jian)探傷(shang)效果差(cha)，同時(shi)這(zhe)么大(da)(da)的(de)電(dian)(dian)流(liu)(liu)其(qi)(qi)用(yong)電(dian)(dian)功(gong)率太大(da)(da)，其(qi)(qi)縱(zong)向又(you)無法(fa)采(cai)(cai)用(yong)線圈磁(ci)(ci)(ci)(ci)化。所以大(da)(da)型帶(dai)軸(zhou)齒(chi)(chi)(chi)輪(lun)無法(fa)一(yi)次(ci)性(xing)復(fu)合磁(ci)(ci)(ci)(ci)化。綜上所述，本設(she)備采(cai)(cai)用(yong)十字交(jiao)叉(cha)磁(ci)(ci)(ci)(ci)軛(e)旋轉(zhuan)磁(ci)(ci)(ci)(ci)場分段(duan)磁(ci)(ci)(ci)(ci)化，即(ji)采(cai)(cai)用(yong)二只磁(ci)(ci)(ci)(ci)軛(e)鐵芯組成(cheng)(cheng)空間(jian)(jian)十字形(xing)，形(xing)成(cheng)(cheng)二個(ge)方(fang)(fang)向的(de)磁(ci)(ci)(ci)(ci)場，對(dui)齒(chi)(chi)(chi)輪(lun)進行電(dian)(dian)磁(ci)(ci)(ci)(ci)感應(ying)復(fu)合磁(ci)(ci)(ci)(ci)化，由于(yu)采(cai)(cai)用(yong)二只磁(ci)(ci)(ci)(ci)軛(e)鐵芯組成(cheng)(cheng)空間(jian)(jian)十字形(xing)，且(qie)二只磁(ci)(ci)(ci)(ci)軛(e)線圈分別通(tong)入交(jiao)流(liu)(liu)工頻電(dian)(dian)AB相(xiang)(xiang)和(he)BC相(xiang)(xiang)，由于(yu)交(jiao)流(liu)(liu)工頻電(dian)(dian)AB相(xiang)(xiang)和(he)BC相(xiang)(xiang)其(qi)(qi)相(xiang)(xiang)位差(cha)為1200，所以其(qi)(qi)產(chan)生的(de)磁(ci)(ci)(ci)(ci)場形(xing)成(cheng)(cheng)一(yi)個(ge)旋轉(zhuan)磁(ci)(ci)(ci)(ci)場。其(qi)(qi)旋轉(zhuan)磁(ci)(ci)(ci)(ci)場作用(yong)于(yu)工件時(shi)在任何時(shi)刻(ke)與裂(lie)紋缺陷都有(you)交(jiao)叉(cha)垂直(zhi)，故能(neng)(neng)檢測出(chu)齒(chi)(chi)(chi)輪(lun)上任何方(fang)(fang)向的(de)裂(lie)紋缺陷。本磁(ci)(ci)(ci)(ci)化方(fang)(fang)法(fa)適(shi)合連續法(fa)探傷(shang)，在不破壞齒(chi)(chi)(chi)輪(lun)外(wai)觀質量(liang)和(he)金相(xiang)(xiang)組織的(de)情況下，作直(zhi)觀顯示檢查。設(she)備采(cai)(cai)用(yong)人(ren)機界(jie)面系(xi)(xi)統(tong)(tong)，進行人(ren)機對(dui)話。通(tong)過人(ren)機界(jie)面系(xi)(xi)統(tong)(tong)和(he)PLC系(xi)(xi)統(tong)(tong)有(you)機的(de)結(jie)合和(he)通(tong)訊，設(she)置(zhi)的(de)所有(you)功(gong)能(neng)(neng)動作，均可(ke)在人(ren)機界(jie)面完成(cheng)(cheng)。
