拖泵銑(xian)齒方(fang)法(fa)和工藝過(guo)程

在(zai)普通臥(wo)式(shi)銑(xian)(xian)(xian)床上，采用帶(dai)有(you)轉盤的(de)(de)分(fen)(fen)度(du)(du)頭(tou)(tou)(tou)進行分(fen)(fen)度(du)(du)。具(ju)體(ti)方法是想將齒(chi)(chi)(chi)坯(pi)固定在(zai)分(fen)(fen)度(du)(du)頭(tou)(tou)(tou)上，見 調整分(fen)(fen)度(du)(du)頭(tou)(tou)(tou)傾角，將分(fen)(fen)度(du)(du)頭(tou)(tou)(tou)扳起一(yi)(yi)個角度(du)(du)，該角度(du)(du)等于(yu)錐(zhui)齒(chi)(chi)(chi)輪根錐(zhui)角δf，用切痕法使銑(xian)(xian)(xian)刀廓形(xing) 的(de)(de)對稱線對準齒(chi)(chi)(chi)坯(pi)的(de)(de)中(zhong)(zhong)心，調整切削深度(du)(du)，以(yi)大(da)端為基(ji)準，將工作(zuo)臺(tai)升高一(yi)(yi)個大(da)端全(quan)齒(chi)(chi)(chi)高后(hou)，先銑(xian)(xian)(xian)齒(chi)(chi)(chi) 槽的(de)(de)中(zhong)(zhong)部(bu)，由(you)于(yu)此(ci)時(shi)采用的(de)(de)直齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪成形(xing)銑(xian)(xian)(xian)刀的(de)(de)厚(hou)度(du)(du)是按照略小(xiao)于(yu)錐(zhui)齒(chi)(chi)(chi)輪小(xiao)端的(de)(de)齒(chi)(chi)(chi)槽寬度(du)(du)設計(ji)的(de)(de)， 所以(yi)齒(chi)(chi)(chi)槽中(zhong)(zhong)部(bu)銑(xian)(xian)(xian)好(hao)后(hou)，齒(chi)(chi)(chi)輪大(da)端和兩側面(mian)還有(you)一(yi)(yi)定加(jia)工余量，因此(ci)，還要對上述部(bu)位進行加(jia)工。

此時(shi)， 將分(fen)度頭(tou)(tou)底(di)(di)座在水(shui)平面旋(xuan)轉(zhuan)一個α角，使銑(xian)(xian)刀廓形對稱線和(he)齒坯軸(zhou)線成一個角度，同(tong)時(shi)適(shi)當移動橫向(xiang)(xiang) 工作臺(移動量可(ke)以通過(guo)試(shi)切來確定)，先(xian)將齒槽一側的余(yu)量銑(xian)(xian)去，然后(hou)再將分(fen)度頭(tou)(tou)底(di)(di)座反向(xiang)(xiang)旋(xuan) 轉(zhuan)2α角，橫向(xiang)(xiang)工作臺也反向(xiang)(xiang)移動，銑(xian)(xian)削齒槽的另一側面余(yu)量。
