拖泵銑(xian)齒方法和(he)工藝過程

在(zai)普通臥式銑(xian)(xian)(xian)(xian)床上，采用(yong)帶有轉(zhuan)盤(pan)的分(fen)度(du)頭進行(xing)分(fen)度(du)。具體(ti)方法是想將齒(chi)(chi)(chi)(chi)坯固定(ding)在(zai)分(fen)度(du)頭上，見(jian) 調(diao)整分(fen)度(du)頭傾角，將分(fen)度(du)頭扳起一(yi)個角度(du)，該(gai)角度(du)等于(yu)錐(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪根(gen)錐(zhui)(zhui)角δf，用(yong)切痕法使銑(xian)(xian)(xian)(xian)刀(dao)廓形(xing) 的對稱線對準齒(chi)(chi)(chi)(chi)坯的中(zhong)(zhong)心，調(diao)整切削深度(du)，以大端為基準，將工作臺升高一(yi)個大端全齒(chi)(chi)(chi)(chi)高后，先(xian)銑(xian)(xian)(xian)(xian)齒(chi)(chi)(chi)(chi) 槽(cao)的中(zhong)(zhong)部，由于(yu)此時采用(yong)的直齒(chi)(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪成(cheng)形(xing)銑(xian)(xian)(xian)(xian)刀(dao)的厚度(du)是按照略小(xiao)于(yu)錐(zhui)(zhui)齒(chi)(chi)(chi)(chi)輪小(xiao)端的齒(chi)(chi)(chi)(chi)槽(cao)寬度(du)設計的， 所(suo)以齒(chi)(chi)(chi)(chi)槽(cao)中(zhong)(zhong)部銑(xian)(xian)(xian)(xian)好(hao)后，齒(chi)(chi)(chi)(chi)輪大端和兩側面還有一(yi)定(ding)加工余量，因此，還要對上述部位進行(xing)加工。

此時， 將(jiang)(jiang)分度頭底座(zuo)在(zai)水平面旋轉(zhuan)一(yi)個α角(jiao)，使(shi)銑刀廓(kuo)形對稱線和齒坯(pi)軸線成一(yi)個角(jiao)度，同時適當移(yi)(yi)(yi)動(dong)橫(heng)向(xiang) 工(gong)作(zuo)(zuo)臺(移(yi)(yi)(yi)動(dong)量(liang)可以通過試切來確定(ding))，先將(jiang)(jiang)齒槽一(yi)側(ce)的余(yu)量(liang)銑去(qu)，然后再(zai)將(jiang)(jiang)分度頭底座(zuo)反向(xiang)旋 轉(zhuan)2α角(jiao)，橫(heng)向(xiang)工(gong)作(zuo)(zuo)臺也反向(xiang)移(yi)(yi)(yi)動(dong)，銑削齒槽的另一(yi)側(ce)面余(yu)量(liang)。
