拖泵(beng)銑齒方(fang)法和工藝過程(cheng)
在(zai)普(pu)通臥(wo)式銑(xian)(xian)床上,采用帶(dai)有轉盤的(de)分(fen)度(du)頭進行分(fen)度(du)。具體方法(fa)(fa)是(shi)想將齒(chi)(chi)(chi)(chi)坯固(gu)定在(zai)分(fen)度(du)頭上,見 調整(zheng)分(fen)度(du)頭傾角,將分(fen)度(du)頭扳起一個角度(du),該角度(du)等于錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)根錐(zhui)(zhui)(zhui)角δf,用切痕法(fa)(fa)使(shi)銑(xian)(xian)刀廓形(xing) 的(de)對(dui)(dui)稱線對(dui)(dui)準(zhun)齒(chi)(chi)(chi)(chi)坯的(de)中(zhong)心,調整(zheng)切削深度(du),以大端為(wei)基準(zhun),將工作臺升高(gao)(gao)一個大端全齒(chi)(chi)(chi)(chi)高(gao)(gao)后,先銑(xian)(xian)齒(chi)(chi)(chi)(chi) 槽(cao)的(de)中(zhong)部(bu),由于此時采用的(de)直齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)成(cheng)形(xing)銑(xian)(xian)刀的(de)厚度(du)是(shi)按(an)照(zhao)略小于錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪(lun)小端的(de)齒(chi)(chi)(chi)(chi)槽(cao)寬(kuan)度(du)設計的(de), 所以齒(chi)(chi)(chi)(chi)槽(cao)中(zhong)部(bu)銑(xian)(xian)好后,齒(chi)(chi)(chi)(chi)輪(lun)大端和(he)兩側面還有一定加(jia)工余量,因(yin)此,還要對(dui)(dui)上述(shu)部(bu)位進行加(jia)工。
此時, 將分度頭(tou)(tou)底座在水平面旋轉一個α角(jiao),使銑刀廓形對(dui)稱(cheng)線和齒(chi)坯(pi)軸線成(cheng)一個角(jiao)度,同時適當移(yi)動(dong)橫向(xiang) 工(gong)作臺(tai)(移(yi)動(dong)量可以通(tong)過試(shi)切來確定),先(xian)將齒(chi)槽一側的(de)余量銑去,然后再將分度頭(tou)(tou)底座反向(xiang)旋 轉2α角(jiao),橫向(xiang)工(gong)作臺(tai)也反向(xiang)移(yi)動(dong),銑削齒(chi)槽的(de)另一側面余量。
