拖(tuo)泵銑齒方法和工藝過程(cheng)

在普(pu)通臥式銑(xian)(xian)床上(shang)，采(cai)用(yong)帶有(you)轉盤的(de)(de)分(fen)(fen)度(du)(du)頭(tou)(tou)進(jin)行分(fen)(fen)度(du)(du)。具體方法是(shi)想將齒(chi)(chi)(chi)坯固定(ding)在分(fen)(fen)度(du)(du)頭(tou)(tou)上(shang)，見(jian) 調整(zheng)分(fen)(fen)度(du)(du)頭(tou)(tou)傾角(jiao)(jiao)，將分(fen)(fen)度(du)(du)頭(tou)(tou)扳起一(yi)個(ge)角(jiao)(jiao)度(du)(du)，該角(jiao)(jiao)度(du)(du)等于錐(zhui)齒(chi)(chi)(chi)輪根(gen)錐(zhui)角(jiao)(jiao)δf，用(yong)切痕(hen)法使銑(xian)(xian)刀廓形 的(de)(de)對稱線對準(zhun)齒(chi)(chi)(chi)坯的(de)(de)中(zhong)心，調整(zheng)切削(xue)深度(du)(du)，以(yi)大(da)端為基準(zhun)，將工(gong)(gong)作臺升高一(yi)個(ge)大(da)端全(quan)齒(chi)(chi)(chi)高后，先銑(xian)(xian)齒(chi)(chi)(chi) 槽的(de)(de)中(zhong)部(bu)，由(you)于此時采(cai)用(yong)的(de)(de)直齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪成形銑(xian)(xian)刀的(de)(de)厚度(du)(du)是(shi)按(an)照略小于錐(zhui)齒(chi)(chi)(chi)輪小端的(de)(de)齒(chi)(chi)(chi)槽寬度(du)(du)設計(ji)的(de)(de)， 所以(yi)齒(chi)(chi)(chi)槽中(zhong)部(bu)銑(xian)(xian)好后，齒(chi)(chi)(chi)輪大(da)端和兩(liang)側面(mian)還有(you)一(yi)定(ding)加工(gong)(gong)余量，因此，還要(yao)對上(shang)述部(bu)位進(jin)行加工(gong)(gong)。

此時， 將(jiang)分度頭底座在水平面(mian)旋(xuan)轉一(yi)個α角，使銑(xian)刀廓形(xing)對稱(cheng)線和齒(chi)坯軸線成(cheng)一(yi)個角度，同時適當移動橫向 工作(zuo)臺(tai)(移動量可以通過試切(qie)來確(que)定)，先將(jiang)齒(chi)槽(cao)(cao)一(yi)側的余量銑(xian)去，然后(hou)再將(jiang)分度頭底座反向旋(xuan) 轉2α角，橫向工作(zuo)臺(tai)也反向移動，銑(xian)削(xue)齒(chi)槽(cao)(cao)的另一(yi)側面(mian)余量。
