拖泵銑齒方法和(he)工藝過程(cheng)
在普通(tong)臥式銑(xian)床上(shang),采用(yong)帶(dai)有轉盤的(de)分(fen)度(du)(du)頭(tou)(tou)進行(xing)分(fen)度(du)(du)。具體方法(fa)是(shi)想將(jiang)齒(chi)(chi)(chi)(chi)坯固定(ding)在分(fen)度(du)(du)頭(tou)(tou)上(shang),見 調整分(fen)度(du)(du)頭(tou)(tou)傾(qing)角,將(jiang)分(fen)度(du)(du)頭(tou)(tou)扳起一個角度(du)(du),該角度(du)(du)等于(yu)錐齒(chi)(chi)(chi)(chi)輪(lun)(lun)根錐角δf,用(yong)切痕法(fa)使銑(xian)刀(dao)廓形 的(de)對(dui)稱線對(dui)準齒(chi)(chi)(chi)(chi)坯的(de)中(zhong)心,調整切削深(shen)度(du)(du),以大端(duan)為基準,將(jiang)工(gong)作(zuo)臺升高一個大端(duan)全(quan)齒(chi)(chi)(chi)(chi)高后(hou),先銑(xian)齒(chi)(chi)(chi)(chi) 槽(cao)的(de)中(zhong)部,由于(yu)此時采用(yong)的(de)直齒(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)輪(lun)(lun)成形銑(xian)刀(dao)的(de)厚度(du)(du)是(shi)按照略小(xiao)于(yu)錐齒(chi)(chi)(chi)(chi)輪(lun)(lun)小(xiao)端(duan)的(de)齒(chi)(chi)(chi)(chi)槽(cao)寬度(du)(du)設計的(de), 所以齒(chi)(chi)(chi)(chi)槽(cao)中(zhong)部銑(xian)好后(hou),齒(chi)(chi)(chi)(chi)輪(lun)(lun)大端(duan)和兩側(ce)面還有一定(ding)加(jia)工(gong)余量,因此,還要對(dui)上(shang)述部位進行(xing)加(jia)工(gong)。
此時(shi), 將(jiang)分度頭底座在水(shui)平(ping)面(mian)旋轉(zhuan)一(yi)(yi)個(ge)α角(jiao),使銑(xian)刀廓形對稱線(xian)和齒坯軸線(xian)成一(yi)(yi)個(ge)角(jiao)度,同時(shi)適(shi)當移動橫(heng)向(xiang) 工(gong)作(zuo)臺(tai)(移動量可以通過試切來確定),先將(jiang)齒槽(cao)一(yi)(yi)側的余量銑(xian)去,然后再將(jiang)分度頭底座反(fan)向(xiang)旋 轉(zhuan)2α角(jiao),橫(heng)向(xiang)工(gong)作(zuo)臺(tai)也(ye)反(fan)向(xiang)移動,銑(xian)削齒槽(cao)的另一(yi)(yi)側面(mian)余量。
