珩(heng)磨機(ji):

       利用珩磨頭珩磨工件精加工表面的磨床。主要用在汽車、拖拉機、液壓件、軸承、航空等制造業中珩磨工件的孔。珩磨機有立式和臥式兩種。氣動活塞桿

不同類(lei)別及特點:

       立式珩(heng)(heng)(heng)(heng)(heng)磨(mo)機(ji)的(de)(de)(de)(de)主軸(zhou)工(gong)(gong)(gong)(gong)(gong)(gong)作(zuo)行(xing)程較(jiao)短，適用于珩(heng)(heng)(heng)(heng)(heng)磨(mo)缸體(ti)(ti)和(he)箱體(ti)(ti)孔(kong)等。鑲(xiang)嵌有油石的(de)(de)(de)(de)珩(heng)(heng)(heng)(heng)(heng)磨(mo)頭(tou)由(you)豎直安(an)置的(de)(de)(de)(de)主軸(zhou)帶動(dong)(dong)(dong)旋(xuan)轉(zhuan)，同(tong)時在(zai)液(ye)壓(ya)裝置的(de)(de)(de)(de)驅動(dong)(dong)(dong)下作(zuo)垂直往復進給(gei)(gei)運動(dong)(dong)(dong)(見機(ji)床)。臥式珩(heng)(heng)(heng)(heng)(heng)磨(mo)機(ji)的(de)(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)(gong)作(zuo)行(xing)程較(jiao)長，適用于珩(heng)(heng)(heng)(heng)(heng)磨(mo)深孔(kong)，深度可(ke)達3000毫米(mi)。水平(ping)安(an)置的(de)(de)(de)(de)珩(heng)(heng)(heng)(heng)(heng)磨(mo)頭(tou)不旋(xuan)轉(zhuan)，只作(zuo)軸(zhou)向往復運動(dong)(dong)(dong)，工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)(jian)由(you)主軸(zhou)帶動(dong)(dong)(dong)旋(xuan)轉(zhuan)，床身中部設(she)有支承(cheng)工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)(jian)的(de)(de)(de)(de)中心架和(he)支承(cheng)珩(heng)(heng)(heng)(heng)(heng)磨(mo)桿的(de)(de)(de)(de)導向架。在(zai)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)過程中，珩(heng)(heng)(heng)(heng)(heng)磨(mo)頭(tou)的(de)(de)(de)(de)油石在(zai)脹縮機(ji)構作(zuo)用下作(zuo)徑向進給(gei)(gei)，把工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)(jian)逐(zhu)步加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)到所需尺寸。新型(xing)的(de)(de)(de)(de)珩(heng)(heng)(heng)(heng)(heng)磨(mo)機(ji)多采用液(ye)壓(ya)脹縮的(de)(de)(de)(de)珩(heng)(heng)(heng)(heng)(heng)磨(mo)頭(tou)。珩(heng)(heng)(heng)(heng)(heng)磨(mo)機(ji)大多是半自(zi)動(dong)(dong)(dong)的(de)(de)(de)(de)，常帶有自(zi)動(dong)(dong)(dong)測量裝置,還可(ke)納入自(zi)動(dong)(dong)(dong)生產線工(gong)(gong)(gong)(gong)(gong)(gong)作(zuo)。除加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)孔(kong)的(de)(de)(de)(de)珩(heng)(heng)(heng)(heng)(heng)磨(mo)機(ji)外(wai),還有加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)其(qi)他表面(mian)(mian)的(de)(de)(de)(de)外(wai)圓珩(heng)(heng)(heng)(heng)(heng)磨(mo)機(ji)、軸(zhou)承(cheng)滾(gun)道珩(heng)(heng)(heng)(heng)(heng)磨(mo)機(ji)、平(ping)面(mian)(mian)珩(heng)(heng)(heng)(heng)(heng)磨(mo)機(ji)和(he)曲(qu)面(mian)(mian)珩(heng)(heng)(heng)(heng)(heng)磨(mo)機(ji)等。
