拖泵銑齒方法和工藝過程

在(zai)普通臥(wo)式銑(xian)(xian)床上(shang)，采(cai)用帶有轉盤的(de)分(fen)度(du)(du)頭(tou)(tou)進行(xing)分(fen)度(du)(du)。具(ju)體方法是想將(jiang)齒(chi)(chi)(chi)(chi)坯(pi)固定在(zai)分(fen)度(du)(du)頭(tou)(tou)上(shang)，見 調整(zheng)分(fen)度(du)(du)頭(tou)(tou)傾角(jiao)，將(jiang)分(fen)度(du)(du)頭(tou)(tou)扳(ban)起(qi)一個角(jiao)度(du)(du)，該角(jiao)度(du)(du)等于錐齒(chi)(chi)(chi)(chi)輪(lun)根錐角(jiao)δf，用切痕法使銑(xian)(xian)刀廓形(xing) 的(de)對(dui)(dui)稱線對(dui)(dui)準齒(chi)(chi)(chi)(chi)坯(pi)的(de)中(zhong)(zhong)心，調整(zheng)切削深度(du)(du)，以大端為基準，將(jiang)工作臺升(sheng)高一個大端全齒(chi)(chi)(chi)(chi)高后，先銑(xian)(xian)齒(chi)(chi)(chi)(chi) 槽的(de)中(zhong)(zhong)部，由于此(ci)時(shi)采(cai)用的(de)直齒(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)輪(lun)成形(xing)銑(xian)(xian)刀的(de)厚度(du)(du)是按(an)照略小于錐齒(chi)(chi)(chi)(chi)輪(lun)小端的(de)齒(chi)(chi)(chi)(chi)槽寬度(du)(du)設計的(de)， 所(suo)以齒(chi)(chi)(chi)(chi)槽中(zhong)(zhong)部銑(xian)(xian)好后，齒(chi)(chi)(chi)(chi)輪(lun)大端和兩側面(mian)還有一定加工余量，因此(ci)，還要對(dui)(dui)上(shang)述部位進行(xing)加工。

此時(shi)(shi)， 將分度(du)頭(tou)底座在(zai)水(shui)平面旋(xuan)轉一(yi)個α角，使(shi)銑(xian)刀廓形對稱線和齒(chi)(chi)坯軸線成一(yi)個角度(du)，同時(shi)(shi)適(shi)當移動(dong)橫向(xiang) 工(gong)作臺(tai)(tai)(移動(dong)量可以通過試切來確定)，先將齒(chi)(chi)槽(cao)一(yi)側的(de)余量銑(xian)去(qu)，然后再將分度(du)頭(tou)底座反向(xiang)旋(xuan) 轉2α角，橫向(xiang)工(gong)作臺(tai)(tai)也反向(xiang)移動(dong)，銑(xian)削齒(chi)(chi)槽(cao)的(de)另一(yi)側面余量。
