拖泵銑(xian)齒方法和工藝過程

在普(pu)通臥式銑(xian)(xian)(xian)床(chuang)上(shang)，采用帶有(you)轉盤的分(fen)度(du)頭(tou)(tou)進行分(fen)度(du)。具體方法(fa)是想將齒(chi)(chi)(chi)(chi)(chi)坯固定在分(fen)度(du)頭(tou)(tou)上(shang)，見 調(diao)整(zheng)分(fen)度(du)頭(tou)(tou)傾(qing)角，將分(fen)度(du)頭(tou)(tou)扳起一(yi)個角度(du)，該(gai)角度(du)等于錐齒(chi)(chi)(chi)(chi)(chi)輪根錐角δf，用切痕(hen)法(fa)使(shi)銑(xian)(xian)(xian)刀廓形 的對(dui)(dui)稱線對(dui)(dui)準齒(chi)(chi)(chi)(chi)(chi)坯的中心，調(diao)整(zheng)切削深度(du)，以大端(duan)為基準，將工(gong)作(zuo)臺(tai)升高(gao)一(yi)個大端(duan)全齒(chi)(chi)(chi)(chi)(chi)高(gao)后，先銑(xian)(xian)(xian)齒(chi)(chi)(chi)(chi)(chi) 槽(cao)(cao)的中部(bu)，由于此時采用的直齒(chi)(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)(chi)輪成形銑(xian)(xian)(xian)刀的厚度(du)是按照(zhao)略小(xiao)于錐齒(chi)(chi)(chi)(chi)(chi)輪小(xiao)端(duan)的齒(chi)(chi)(chi)(chi)(chi)槽(cao)(cao)寬度(du)設計的， 所以齒(chi)(chi)(chi)(chi)(chi)槽(cao)(cao)中部(bu)銑(xian)(xian)(xian)好后，齒(chi)(chi)(chi)(chi)(chi)輪大端(duan)和兩側面還有(you)一(yi)定加工(gong)余量，因(yin)此，還要對(dui)(dui)上(shang)述部(bu)位進行加工(gong)。

此時(shi)， 將(jiang)分(fen)(fen)度(du)頭底座在(zai)水平面旋(xuan)轉(zhuan)一(yi)(yi)個α角(jiao)，使銑(xian)刀廓(kuo)形對稱線和齒(chi)坯軸線成一(yi)(yi)個角(jiao)度(du)，同時(shi)適當移(yi)動(dong)(dong)(dong)橫(heng)向 工作臺(tai)(移(yi)動(dong)(dong)(dong)量可以通過(guo)試切(qie)來確定)，先(xian)將(jiang)齒(chi)槽(cao)一(yi)(yi)側的(de)余(yu)量銑(xian)去，然后再將(jiang)分(fen)(fen)度(du)頭底座反向旋(xuan) 轉(zhuan)2α角(jiao)，橫(heng)向工作臺(tai)也反向移(yi)動(dong)(dong)(dong)，銑(xian)削齒(chi)槽(cao)的(de)另一(yi)(yi)側面余(yu)量。
