拖泵(beng)銑齒方法和(he)工藝過程

在(zai)普通(tong)臥式銑(xian)床(chuang)上(shang)(shang)，采(cai)用(yong)帶有轉(zhuan)盤的(de)分(fen)(fen)(fen)度(du)(du)(du)(du)頭(tou)進行(xing)(xing)分(fen)(fen)(fen)度(du)(du)(du)(du)。具體(ti)方法是(shi)想將(jiang)齒(chi)(chi)(chi)(chi)(chi)坯固(gu)定在(zai)分(fen)(fen)(fen)度(du)(du)(du)(du)頭(tou)上(shang)(shang)，見 調整分(fen)(fen)(fen)度(du)(du)(du)(du)頭(tou)傾角(jiao)(jiao)，將(jiang)分(fen)(fen)(fen)度(du)(du)(du)(du)頭(tou)扳起(qi)一個角(jiao)(jiao)度(du)(du)(du)(du)，該(gai)角(jiao)(jiao)度(du)(du)(du)(du)等于錐(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)根錐(zhui)角(jiao)(jiao)δf，用(yong)切(qie)痕(hen)法使(shi)銑(xian)刀廓形(xing) 的(de)對稱線對準(zhun)齒(chi)(chi)(chi)(chi)(chi)坯的(de)中(zhong)心，調整切(qie)削深度(du)(du)(du)(du)，以(yi)(yi)大端為基(ji)準(zhun)，將(jiang)工(gong)(gong)作臺升高(gao)一個大端全(quan)齒(chi)(chi)(chi)(chi)(chi)高(gao)后(hou)，先銑(xian)齒(chi)(chi)(chi)(chi)(chi) 槽的(de)中(zhong)部，由于此(ci)時采(cai)用(yong)的(de)直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)成形(xing)銑(xian)刀的(de)厚(hou)度(du)(du)(du)(du)是(shi)按照略(lve)小(xiao)于錐(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)小(xiao)端的(de)齒(chi)(chi)(chi)(chi)(chi)槽寬(kuan)度(du)(du)(du)(du)設計的(de)， 所以(yi)(yi)齒(chi)(chi)(chi)(chi)(chi)槽中(zhong)部銑(xian)好后(hou)，齒(chi)(chi)(chi)(chi)(chi)輪(lun)大端和兩側面還有一定加(jia)工(gong)(gong)余量，因此(ci)，還要對上(shang)(shang)述(shu)部位進行(xing)(xing)加(jia)工(gong)(gong)。

此(ci)時(shi)， 將分度頭(tou)底(di)(di)座在水平面旋轉(zhuan)一(yi)(yi)(yi)(yi)個α角(jiao)(jiao)，使(shi)銑(xian)刀廓形對稱(cheng)線(xian)和齒坯(pi)軸線(xian)成一(yi)(yi)(yi)(yi)個角(jiao)(jiao)度，同時(shi)適當移動(dong)橫向 工作(zuo)臺(tai)(移動(dong)量可以通(tong)過試切來確定)，先將齒槽一(yi)(yi)(yi)(yi)側的(de)余量銑(xian)去，然(ran)后再將分度頭(tou)底(di)(di)座反(fan)向旋 轉(zhuan)2α角(jiao)(jiao)，橫向工作(zuo)臺(tai)也反(fan)向移動(dong)，銑(xian)削齒槽的(de)另一(yi)(yi)(yi)(yi)側面余量。
