拖泵銑齒(chi)方法和工(gong)藝過程

在普通臥(wo)式(shi)銑(xian)(xian)床(chuang)上(shang)，采用(yong)帶有(you)轉盤的分(fen)(fen)(fen)度(du)(du)(du)(du)頭進(jin)行分(fen)(fen)(fen)度(du)(du)(du)(du)。具體方法是想將(jiang)齒(chi)(chi)(chi)坯(pi)固定(ding)在分(fen)(fen)(fen)度(du)(du)(du)(du)頭上(shang)，見 調(diao)整(zheng)分(fen)(fen)(fen)度(du)(du)(du)(du)頭傾角(jiao)，將(jiang)分(fen)(fen)(fen)度(du)(du)(du)(du)頭扳(ban)起一個角(jiao)度(du)(du)(du)(du)，該角(jiao)度(du)(du)(du)(du)等于錐齒(chi)(chi)(chi)輪(lun)根錐角(jiao)δf，用(yong)切(qie)痕法使銑(xian)(xian)刀廓形 的對(dui)(dui)稱線對(dui)(dui)準齒(chi)(chi)(chi)坯(pi)的中(zhong)(zhong)心，調(diao)整(zheng)切(qie)削深度(du)(du)(du)(du)，以(yi)大端為基準，將(jiang)工(gong)作臺升高一個大端全齒(chi)(chi)(chi)高后(hou)，先銑(xian)(xian)齒(chi)(chi)(chi) 槽的中(zhong)(zhong)部，由于此時采用(yong)的直(zhi)齒(chi)(chi)(chi)錐齒(chi)(chi)(chi)輪(lun)成形銑(xian)(xian)刀的厚度(du)(du)(du)(du)是按照略小(xiao)于錐齒(chi)(chi)(chi)輪(lun)小(xiao)端的齒(chi)(chi)(chi)槽寬度(du)(du)(du)(du)設計的， 所以(yi)齒(chi)(chi)(chi)槽中(zhong)(zhong)部銑(xian)(xian)好后(hou)，齒(chi)(chi)(chi)輪(lun)大端和兩(liang)側面還有(you)一定(ding)加工(gong)余量，因此，還要對(dui)(dui)上(shang)述部位進(jin)行加工(gong)。

此時， 將分度(du)頭(tou)底座在(zai)水(shui)平面(mian)旋轉(zhuan)一(yi)個(ge)α角，使(shi)銑(xian)刀廓形對稱(cheng)線和齒(chi)(chi)坯軸線成一(yi)個(ge)角度(du)，同時適當移(yi)動橫(heng)向(xiang) 工作(zuo)臺(移(yi)動量可(ke)以通過試切來確定)，先將齒(chi)(chi)槽一(yi)側的(de)余(yu)量銑(xian)去，然后再將分度(du)頭(tou)底座反(fan)向(xiang)旋 轉(zhuan)2α角，橫(heng)向(xiang)工作(zuo)臺也反(fan)向(xiang)移(yi)動，銑(xian)削齒(chi)(chi)槽的(de)另一(yi)側面(mian)余(yu)量。
