拖泵銑(xian)齒方法和工藝過(guo)程
在(zai)(zai)普通臥(wo)式銑(xian)床上(shang),采用(yong)(yong)帶有(you)轉(zhuan)盤的(de)分(fen)(fen)度(du)(du)(du)(du)頭進行分(fen)(fen)度(du)(du)(du)(du)。具(ju)體(ti)方(fang)法(fa)是想將齒(chi)(chi)坯(pi)固定在(zai)(zai)分(fen)(fen)度(du)(du)(du)(du)頭上(shang),見(jian) 調(diao)整分(fen)(fen)度(du)(du)(du)(du)頭傾(qing)角(jiao),將分(fen)(fen)度(du)(du)(du)(du)頭扳起一(yi)個(ge)(ge)角(jiao)度(du)(du)(du)(du),該(gai)角(jiao)度(du)(du)(du)(du)等于錐(zhui)齒(chi)(chi)輪根錐(zhui)角(jiao)δf,用(yong)(yong)切痕法(fa)使銑(xian)刀(dao)廓(kuo)形(xing) 的(de)對(dui)稱(cheng)線對(dui)準(zhun)齒(chi)(chi)坯(pi)的(de)中(zhong)心,調(diao)整切削深(shen)度(du)(du)(du)(du),以大端(duan)(duan)為基準(zhun),將工(gong)作(zuo)臺升高一(yi)個(ge)(ge)大端(duan)(duan)全(quan)齒(chi)(chi)高后,先銑(xian)齒(chi)(chi) 槽的(de)中(zhong)部(bu),由于此時采用(yong)(yong)的(de)直齒(chi)(chi)錐(zhui)齒(chi)(chi)輪成(cheng)形(xing)銑(xian)刀(dao)的(de)厚度(du)(du)(du)(du)是按照略小于錐(zhui)齒(chi)(chi)輪小端(duan)(duan)的(de)齒(chi)(chi)槽寬度(du)(du)(du)(du)設計的(de), 所以齒(chi)(chi)槽中(zhong)部(bu)銑(xian)好后,齒(chi)(chi)輪大端(duan)(duan)和兩側面(mian)還(huan)(huan)有(you)一(yi)定加(jia)工(gong)余量(liang),因此,還(huan)(huan)要(yao)對(dui)上(shang)述部(bu)位進行加(jia)工(gong)。
此時, 將(jiang)分(fen)度(du)頭(tou)底(di)座在(zai)水平(ping)面旋轉(zhuan)一(yi)(yi)個(ge)α角,使銑(xian)刀廓(kuo)形對稱線(xian)和齒(chi)坯(pi)軸線(xian)成一(yi)(yi)個(ge)角度(du),同(tong)時適(shi)當移(yi)(yi)動橫(heng)(heng)向 工(gong)作臺(移(yi)(yi)動量(liang)(liang)可以通(tong)過試(shi)切來(lai)確(que)定),先(xian)將(jiang)齒(chi)槽一(yi)(yi)側(ce)的余量(liang)(liang)銑(xian)去(qu),然(ran)后再將(jiang)分(fen)度(du)頭(tou)底(di)座反向旋 轉(zhuan)2α角,橫(heng)(heng)向工(gong)作臺也反向移(yi)(yi)動,銑(xian)削(xue)齒(chi)槽的另一(yi)(yi)側(ce)面余量(liang)(liang)。
