拖泵(beng)銑齒(chi)方法和工藝過程

在普通(tong)臥(wo)式銑(xian)(xian)(xian)床上(shang)(shang)，采用(yong)帶有(you)轉盤的(de)(de)(de)分(fen)(fen)(fen)度(du)(du)頭(tou)進(jin)行(xing)分(fen)(fen)(fen)度(du)(du)。具(ju)體方法是想將齒(chi)(chi)(chi)(chi)坯固定在分(fen)(fen)(fen)度(du)(du)頭(tou)上(shang)(shang)，見 調整分(fen)(fen)(fen)度(du)(du)頭(tou)傾角(jiao)，將分(fen)(fen)(fen)度(du)(du)頭(tou)扳起一(yi)個角(jiao)度(du)(du)，該角(jiao)度(du)(du)等于(yu)(yu)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)根錐(zhui)角(jiao)δf，用(yong)切(qie)痕法使銑(xian)(xian)(xian)刀(dao)廓形 的(de)(de)(de)對(dui)(dui)稱線對(dui)(dui)準齒(chi)(chi)(chi)(chi)坯的(de)(de)(de)中(zhong)(zhong)心(xin)，調整切(qie)削深度(du)(du)，以大端為基準，將工(gong)作(zuo)臺(tai)升高一(yi)個大端全齒(chi)(chi)(chi)(chi)高后，先銑(xian)(xian)(xian)齒(chi)(chi)(chi)(chi) 槽(cao)的(de)(de)(de)中(zhong)(zhong)部(bu)，由于(yu)(yu)此(ci)時(shi)采用(yong)的(de)(de)(de)直(zhi)齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)成形銑(xian)(xian)(xian)刀(dao)的(de)(de)(de)厚度(du)(du)是按照略小于(yu)(yu)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)小端的(de)(de)(de)齒(chi)(chi)(chi)(chi)槽(cao)寬度(du)(du)設計的(de)(de)(de)， 所以齒(chi)(chi)(chi)(chi)槽(cao)中(zhong)(zhong)部(bu)銑(xian)(xian)(xian)好后，齒(chi)(chi)(chi)(chi)輪(lun)大端和兩側面還(huan)有(you)一(yi)定加工(gong)余(yu)量(liang)，因此(ci)，還(huan)要對(dui)(dui)上(shang)(shang)述(shu)部(bu)位進(jin)行(xing)加工(gong)。

此時(shi)(shi)， 將(jiang)(jiang)分度頭底(di)(di)座在水平面旋(xuan)轉一個α角(jiao)，使銑刀(dao)廓(kuo)形對稱線和(he)齒坯軸(zhou)線成一個角(jiao)度，同時(shi)(shi)適當移動橫向(xiang)(xiang)(xiang) 工作臺(移動量可以(yi)通過試切來確定)，先將(jiang)(jiang)齒槽一側(ce)的余量銑去(qu)，然后再(zai)將(jiang)(jiang)分度頭底(di)(di)座反(fan)向(xiang)(xiang)(xiang)旋(xuan) 轉2α角(jiao)，橫向(xiang)(xiang)(xiang)工作臺也反(fan)向(xiang)(xiang)(xiang)移動，銑削(xue)齒槽的另一側(ce)面余量。
