拖泵銑齒(chi)方(fang)法和工藝過程(cheng)
在普通(tong)臥(wo)式銑(xian)(xian)床上(shang),采(cai)用(yong)帶有轉盤(pan)的(de)分(fen)(fen)度(du)頭進行(xing)分(fen)(fen)度(du)。具體(ti)方法是想(xiang)將(jiang)齒(chi)(chi)坯(pi)固定(ding)在分(fen)(fen)度(du)頭上(shang),見 調整分(fen)(fen)度(du)頭傾角(jiao)(jiao),將(jiang)分(fen)(fen)度(du)頭扳起一(yi)(yi)個(ge)角(jiao)(jiao)度(du),該角(jiao)(jiao)度(du)等于錐齒(chi)(chi)輪根錐角(jiao)(jiao)δf,用(yong)切(qie)痕法使銑(xian)(xian)刀廓形(xing) 的(de)對(dui)稱線對(dui)準齒(chi)(chi)坯(pi)的(de)中(zhong)心,調整切(qie)削深度(du),以大(da)端(duan)為基準,將(jiang)工作(zuo)臺升(sheng)高(gao)(gao)一(yi)(yi)個(ge)大(da)端(duan)全齒(chi)(chi)高(gao)(gao)后,先銑(xian)(xian)齒(chi)(chi) 槽的(de)中(zhong)部(bu)(bu),由于此(ci)時采(cai)用(yong)的(de)直齒(chi)(chi)錐齒(chi)(chi)輪成形(xing)銑(xian)(xian)刀的(de)厚度(du)是按(an)照略小(xiao)于錐齒(chi)(chi)輪小(xiao)端(duan)的(de)齒(chi)(chi)槽寬度(du)設計的(de), 所以齒(chi)(chi)槽中(zhong)部(bu)(bu)銑(xian)(xian)好后,齒(chi)(chi)輪大(da)端(duan)和兩側面還(huan)有一(yi)(yi)定(ding)加工余量,因此(ci),還(huan)要對(dui)上(shang)述(shu)部(bu)(bu)位進行(xing)加工。
此時(shi), 將分(fen)度(du)頭底(di)座在水平面旋轉(zhuan)一個(ge)α角,使銑(xian)(xian)刀廓形對(dui)稱(cheng)線(xian)和(he)齒坯軸線(xian)成(cheng)一個(ge)角度(du),同時(shi)適(shi)當移(yi)動(dong)橫向 工(gong)作臺(移(yi)動(dong)量可(ke)以通過(guo)試切(qie)來確定(ding)),先將齒槽一側的(de)余量銑(xian)(xian)去(qu),然(ran)后再(zai)將分(fen)度(du)頭底(di)座反(fan)向旋 轉(zhuan)2α角,橫向工(gong)作臺也反(fan)向移(yi)動(dong),銑(xian)(xian)削(xue)齒槽的(de)另(ling)一側面余量。
