拖泵銑(xian)齒(chi)方(fang)法和(he)工藝(yi)過程(cheng)

在普通(tong)臥式銑(xian)床上，采用(yong)(yong)(yong)帶(dai)有轉盤的(de)(de)(de)(de)分(fen)(fen)度(du)頭(tou)進(jin)行分(fen)(fen)度(du)。具(ju)體方法(fa)是(shi)(shi)想將齒(chi)(chi)(chi)坯(pi)固定在分(fen)(fen)度(du)頭(tou)上，見 調整分(fen)(fen)度(du)頭(tou)傾角，將分(fen)(fen)度(du)頭(tou)扳(ban)起一(yi)個角度(du)，該角度(du)等于錐(zhui)齒(chi)(chi)(chi)輪(lun)根(gen)錐(zhui)角δf，用(yong)(yong)(yong)切痕法(fa)使(shi)銑(xian)刀廓形 的(de)(de)(de)(de)對(dui)稱線對(dui)準齒(chi)(chi)(chi)坯(pi)的(de)(de)(de)(de)中(zhong)心，調整切削深度(du)，以大(da)端(duan)(duan)為基準，將工(gong)作臺升高一(yi)個大(da)端(duan)(duan)全齒(chi)(chi)(chi)高后，先(xian)銑(xian)齒(chi)(chi)(chi) 槽的(de)(de)(de)(de)中(zhong)部(bu)，由于此(ci)時采用(yong)(yong)(yong)的(de)(de)(de)(de)直齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪(lun)成(cheng)形銑(xian)刀的(de)(de)(de)(de)厚度(du)是(shi)(shi)按(an)照略小(xiao)(xiao)于錐(zhui)齒(chi)(chi)(chi)輪(lun)小(xiao)(xiao)端(duan)(duan)的(de)(de)(de)(de)齒(chi)(chi)(chi)槽寬度(du)設計的(de)(de)(de)(de)， 所以齒(chi)(chi)(chi)槽中(zhong)部(bu)銑(xian)好后，齒(chi)(chi)(chi)輪(lun)大(da)端(duan)(duan)和(he)兩側(ce)面還(huan)有一(yi)定加工(gong)余(yu)量，因此(ci)，還(huan)要對(dui)上述部(bu)位進(jin)行加工(gong)。

此時(shi)， 將分度頭(tou)(tou)底(di)座在水平面(mian)旋轉一(yi)個α角，使銑刀(dao)廓形對稱(cheng)線(xian)和齒坯軸線(xian)成一(yi)個角度，同時(shi)適當移動(dong)橫向(xiang)(xiang) 工(gong)作(zuo)臺(tai)(移動(dong)量可(ke)以通(tong)過試切(qie)來確定)，先將齒槽一(yi)側(ce)的余(yu)量銑去，然(ran)后再將分度頭(tou)(tou)底(di)座反向(xiang)(xiang)旋 轉2α角，橫向(xiang)(xiang)工(gong)作(zuo)臺(tai)也反向(xiang)(xiang)移動(dong)，銑削齒槽的另(ling)一(yi)側(ce)面(mian)余(yu)量。
