拖泵銑齒方法和(he)工藝過程
在普通臥式銑床上(shang),采(cai)用帶有轉盤的(de)分(fen)度(du)頭進行分(fen)度(du)。具體方法是想將(jiang)齒(chi)(chi)(chi)(chi)(chi)坯(pi)固定在分(fen)度(du)頭上(shang),見 調(diao)整分(fen)度(du)頭傾角,將(jiang)分(fen)度(du)頭扳起一(yi)個角度(du),該(gai)角度(du)等(deng)于錐齒(chi)(chi)(chi)(chi)(chi)輪(lun)根錐角δf,用切痕法使銑刀廓形 的(de)對稱線對準齒(chi)(chi)(chi)(chi)(chi)坯(pi)的(de)中(zhong)(zhong)心,調(diao)整切削(xue)深度(du),以大(da)端(duan)為(wei)基準,將(jiang)工(gong)(gong)作(zuo)臺(tai)升高一(yi)個大(da)端(duan)全齒(chi)(chi)(chi)(chi)(chi)高后(hou),先(xian)銑齒(chi)(chi)(chi)(chi)(chi) 槽的(de)中(zhong)(zhong)部(bu),由于此(ci)時采(cai)用的(de)直齒(chi)(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)(chi)輪(lun)成形銑刀的(de)厚度(du)是按照略小于錐齒(chi)(chi)(chi)(chi)(chi)輪(lun)小端(duan)的(de)齒(chi)(chi)(chi)(chi)(chi)槽寬度(du)設計的(de), 所以齒(chi)(chi)(chi)(chi)(chi)槽中(zhong)(zhong)部(bu)銑好(hao)后(hou),齒(chi)(chi)(chi)(chi)(chi)輪(lun)大(da)端(duan)和兩側(ce)面還(huan)有一(yi)定加工(gong)(gong)余(yu)量,因此(ci),還(huan)要對上(shang)述部(bu)位進行加工(gong)(gong)。
此時, 將分(fen)度頭(tou)底座(zuo)在水平(ping)面旋轉(zhuan)一(yi)個(ge)α角,使銑(xian)刀廓形對稱線(xian)和齒(chi)坯軸線(xian)成一(yi)個(ge)角度,同時適(shi)當移動橫(heng)向(xiang) 工作臺(移動量(liang)(liang)可(ke)以通過(guo)試(shi)切(qie)來確定),先將齒(chi)槽一(yi)側的余(yu)量(liang)(liang)銑(xian)去,然(ran)后再將分(fen)度頭(tou)底座(zuo)反(fan)(fan)向(xiang)旋 轉(zhuan)2α角,橫(heng)向(xiang)工作臺也(ye)反(fan)(fan)向(xiang)移動,銑(xian)削齒(chi)槽的另一(yi)側面余(yu)量(liang)(liang)。
