花鍵分類

花(hua)(hua)(hua)鍵(jian)(jian)可按(an)齒(chi)(chi)形(xing)、結構兩方面進行分(fen)(fen)類。按(an)齒(chi)(chi)形(xing)分(fen)(fen)類可分(fen)(fen)為(wei)矩(ju)形(xing)花(hua)(hua)(hua)鍵(jian)(jian)和漸(jian)(jian)開(kai)(kai)線(xian)花(hua)(hua)(hua)鍵(jian)(jian)。矩(ju)形(xing)花(hua)(hua)(hua)鍵(jian)(jian)多齒(chi)(chi)工作，承(cheng)載(zai)能力高，對(dui)中性好，導向性好，齒(chi)(chi)根(gen)較(jiao)淺，應力集中較(jiao)小。如汽車(che)變速器輸(shu)入(ru)軸花(hua)(hua)(hua)鍵(jian)(jian)多采(cai)用矩(ju)形(xing)花(hua)(hua)(hua)鍵(jian)(jian)。漸(jian)(jian)開(kai)(kai)線(xian)花(hua)(hua)(hua)鍵(jian)(jian)齒(chi)(chi)廓(kuo)為(wei)漸(jian)(jian)開(kai)(kai)線(xian)，受載(zai)時(shi)齒(chi)(chi)上有徑向力，能起(qi)自動定(ding)心作用，使各(ge)齒(chi)(chi)受力均(jun)勻，強(qiang)度高壽(shou)命長。按(an)結構分(fen)(fen)類可分(fen)(fen)為(wei)內(nei)齒(chi)(chi)和外齒(chi)(chi)。

拉床的分類

外(wai)拉(la)(la)(la)(la)(la)床(chuang)用(yong)于(yu)(yu)外(wai)表(biao)面拉(la)(la)(la)(la)(la)削，主(zhu)要有下列幾種：①立式(shi)外(wai)拉(la)(la)(la)(la)(la)床(chuang)，工(gong)(gong)(gong)(gong)件(jian)固(gu)(gu)定在(zai)工(gong)(gong)(gong)(gong)作(zuo)臺上，垂直設(she)置的(de)主(zhu)溜板帶著拉(la)(la)(la)(la)(la)刀(dao)(dao)自上而下地拉(la)(la)(la)(la)(la)削工(gong)(gong)(gong)(gong)件(jian)，占地面積較小(xiao)。②側拉(la)(la)(la)(la)(la)床(chuang)，臥(wo)式(shi)布局(ju)，拉(la)(la)(la)(la)(la)刀(dao)(dao)固(gu)(gu)定在(zai)側立的(de)溜板上，在(zai)傳動(dong)裝(zhuang)置帶動(dong)下拉(la)(la)(la)(la)(la)削工(gong)(gong)(gong)(gong)件(jian)，便于(yu)(yu)排屑，適用(yong)于(yu)(yu)拉(la)(la)(la)(la)(la)削大(da)平(ping)面、大(da)余量的(de)外(wai)表(biao)面，如(ru)氣缸(gang)體(ti)的(de)大(da)平(ping)面和(he)葉lun盤榫槽(cao)等。③連續拉(la)(la)(la)(la)(la)床(chuang)，較多采用(yong)臥(wo)式(shi)布局(ju)，拉(la)(la)(la)(la)(la)刀(dao)(dao)加(jia)工(gong)(gong)(gong)(gong)，分為工(gong)(gong)(gong)(gong)件(jian)固(gu)(gu)定和(he)拉(la)(la)(la)(la)(la)刀(dao)(dao)固(gu)(gu)定兩類。前者由鏈條帶動(dong)一(yi)組拉(la)(la)(la)(la)(la)刀(dao)(dao)進(jin)行(xing)連續拉(la)(la)(la)(la)(la)削，適用(yong)于(yu)(yu)大(da)型(xing)工(gong)(gong)(gong)(gong)件(jian)；后者由鏈條帶動(dong)多個裝(zhuang)有工(gong)(gong)(gong)(gong)件(jian)的(de)隨行(xing)夾具通過拉(la)(la)(la)(la)(la)刀(dao)(dao)進(jin)行(xing)連續拉(la)(la)(la)(la)(la)削，D型(xing)孔(kong)加(jia)工(gong)(gong)(gong)(gong)，適用(yong)于(yu)(yu)中(zhong)小(xiao)型(xing)工(gong)(gong)(gong)(gong)件(jian)。

我(wo)公(gong)司是一家從事拉(la)(la)床加工、拉(la)(la)刀(dao)(dao)研(yan)磨的企業，拉(la)(la)削范(fan)圍主要有：真圓(yuan)、D型(xing)(xing)、腰型(xing)(xing)、異(yi)型(xing)(xing)、齒型(xing)(xing)、多邊型(xing)(xing)、栓(shuan)槽、鍵槽等。磨刀(dao)(dao)范(fan)圍主要有：圓(yuan)拉(la)(la)刀(dao)(dao)、平面拉(la)(la)刀(dao)(dao)花鍵加工設(she)備

花鍵(jian)銑床(chuang)(chuang)是(shi)常見的(de)(de)花鍵(jian)加(jia)(jia)工(gong)(gong)設(she)備(bei)，E型孔加(jia)(jia)工(gong)(gong)，成(cheng)本低，在汽車行業中(zhong)普遍應用(yong)。滾齒機(ji)床(chuang)(chuang)可(ke)用(yong)于加(jia)(jia)工(gong)(gong)花鍵(jian)，但成(cheng)本比花鍵(jian)銑床(chuang)(chuang)高，一(yi)般用(yong)于加(jia)(jia)工(gong)(gong)有(you)螺旋(xuan)角的(de)(de)花鍵(jian)。插齒機(ji)床(chuang)(chuang)在變(bian)速器二軸花鍵(jian)的(de)(de)加(jia)(jia)工(gong)(gong)中(zhong)應用(yong)較廣。拉齒機(ji)床(chuang)(chuang)在內花鍵(jian)的(de)(de)生產中(zhong)普遍使用(yong)，加(jia)(jia)工(gong)(gong)，主要(yao)有(you)立(li)式(shi)拉床(chuang)(chuang)和臥式(shi)拉床(chuang)(chuang)，立(li)式(shi)拉床(chuang)(chuang)因為可(ke)以(yi)消除工(gong)(gong)件自(zi)重引(yin)起的(de)(de)偏心，所以(yi)應用(yong)較廣，拉削一(yi)件只需要(yao)幾(ji)秒(miao)鐘(zhong)的(de)(de)時間，效率非常高。
