內(nei)燃機(ji)(ji)(ji)氣(qi)(qi)缸(gang)(gang)(gang)套(tao)是發(fa)動(dong)機(ji)(ji)(ji)基(ji)本的(de)(de)(de)(de)部件之一(yi)。它與(yu)活(huo)塞(sai)、活(huo)塞(sai)環(huan)和氣(qi)(qi)缸(gang)(gang)(gang)蓋組(zu)成燃燒(shao)室。汽(qi)油(you)（柴油(you)）和空氣(qi)(qi)的(de)(de)(de)(de)混合物爆炸并(bing)產(chan)(chan)生動(dong)力，終促進機(ji)(ji)(ji)械或車輛的(de)(de)(de)(de)運行。氣(qi)(qi)缸(gang)(gang)(gang)套(tao)分(fen)為干式(shi)氣(qi)(qi)缸(gang)(gang)(gang)套(tao)和濕式(shi)氣(qi)(qi)缸(gang)(gang)(gang)套(tao)兩種。氣(qi)(qi)缸(gang)(gang)(gang)套(tao)材料一(yi)般(ban)為合金鑄鐵，以保證高導熱(re)性(xing)和耐磨性(xing)。缸(gang)(gang)(gang)套(tao)內(nei)孔表面支撐活(huo)塞(sai)和活(huo)塞(sai)環(huan)的(de)(de)(de)(de)上下運動(dong)，因此缸(gang)(gang)(gang)套(tao)內(nei)孔所需的(de)(de)(de)(de)尺(chi)寸精度和位置(zhi)精度非常高，終內(nei)孔加(jia)工(gong)一(yi)般(ban)采用(yong)(yong)(yong)立(li)式(shi)絎(heng)(heng)縫(feng)機(ji)(ji)(ji)床進行。然而(er)，現有(you)的(de)(de)(de)(de)絎(heng)(heng)縫(feng)夾具結構復(fu)雜(za)，不方便(bian)快速(su)操作，只適用(yong)(yong)(yong)于(yu)固定一(yi)種類型的(de)(de)(de)(de)缸(gang)(gang)(gang)套(tao)，不方便(bian)快速(su)切換適用(yong)(yong)(yong)于(yu)不同(tong)類型的(de)(de)(de)(de)缸(gang)(gang)(gang)套(tao)，從而(er)影響缸(gang)(gang)(gang)套(tao)的(de)(de)(de)(de)加(jia)工(gong)效(xiao)率。但熱(re)后恒(heng)齒(chi)(chi)工(gong)藝產(chan)(chan)生的(de)(de)(de)(de)細微恒(heng)線(xian)與(yu)齒(chi)(chi)輪(lun)(lun)運行軸不平行，呈斜(xie)紋狀(zhuang)態。這樣，高速(su)運行時就不會產(chan)(chan)生諧振，齒(chi)(chi)輪(lun)(lun)傳動(dong)噪(zao)聲也大大降低(di)。同(tong)時，恒(heng)齒(chi)(chi)的(de)(de)(de)(de)擠壓和振動(dong)可以降低(di)齒(chi)(chi)面熱(re)處(chu)理的(de)(de)(de)(de)殘余應力，增強齒(chi)(chi)面壓應力，提高齒(chi)(chi)輪(lun)(lun)的(de)(de)(de)(de)使用(yong)(yong)(yong)壽命。
