拖泵銑齒方法(fa)和(he)工藝過程(cheng)
在(zai)普通臥(wo)式(shi)銑(xian)床上(shang),采用(yong)帶(dai)有轉盤的(de)分(fen)(fen)(fen)度(du)(du)(du)頭(tou)(tou)進行(xing)分(fen)(fen)(fen)度(du)(du)(du)。具體方(fang)法是(shi)想將齒(chi)坯固定(ding)在(zai)分(fen)(fen)(fen)度(du)(du)(du)頭(tou)(tou)上(shang),見 調整(zheng)分(fen)(fen)(fen)度(du)(du)(du)頭(tou)(tou)傾角(jiao)(jiao),將分(fen)(fen)(fen)度(du)(du)(du)頭(tou)(tou)扳起一(yi)(yi)個(ge)角(jiao)(jiao)度(du)(du)(du),該角(jiao)(jiao)度(du)(du)(du)等于錐齒(chi)輪根錐角(jiao)(jiao)δf,用(yong)切痕法使銑(xian)刀(dao)廓(kuo)形(xing) 的(de)對(dui)稱(cheng)線對(dui)準齒(chi)坯的(de)中(zhong)(zhong)心,調整(zheng)切削深度(du)(du)(du),以大(da)端(duan)為基準,將工作臺升(sheng)高(gao)(gao)一(yi)(yi)個(ge)大(da)端(duan)全齒(chi)高(gao)(gao)后,先(xian)銑(xian)齒(chi) 槽(cao)的(de)中(zhong)(zhong)部(bu),由于此時采用(yong)的(de)直齒(chi)錐齒(chi)輪成形(xing)銑(xian)刀(dao)的(de)厚度(du)(du)(du)是(shi)按(an)照略小(xiao)于錐齒(chi)輪小(xiao)端(duan)的(de)齒(chi)槽(cao)寬度(du)(du)(du)設(she)計的(de), 所以齒(chi)槽(cao)中(zhong)(zhong)部(bu)銑(xian)好(hao)后,齒(chi)輪大(da)端(duan)和兩側面還(huan)(huan)有一(yi)(yi)定(ding)加工余量,因此,還(huan)(huan)要對(dui)上(shang)述部(bu)位進行(xing)加工。
此(ci)時(shi), 將(jiang)(jiang)分度頭底(di)座(zuo)在水(shui)平面旋轉一(yi)個α角,使銑刀廓形對稱線(xian)(xian)和齒(chi)坯軸線(xian)(xian)成一(yi)個角度,同(tong)時(shi)適(shi)當移(yi)動(dong)(dong)橫向 工(gong)作臺(移(yi)動(dong)(dong)量可以通(tong)過試切(qie)來確定),先將(jiang)(jiang)齒(chi)槽一(yi)側的余量銑去(qu),然后(hou)再將(jiang)(jiang)分度頭底(di)座(zuo)反向旋 轉2α角,橫向工(gong)作臺也反向移(yi)動(dong)(dong),銑削齒(chi)槽的另一(yi)側面余量。
