拖泵銑齒(chi)方法和工藝過程
在(zai)普(pu)通(tong)臥式銑(xian)(xian)床上(shang),采用(yong)帶有(you)轉(zhuan)盤的(de)(de)分度(du)(du)(du)(du)頭(tou)進行分度(du)(du)(du)(du)。具體方法是想將(jiang)齒(chi)(chi)坯固定(ding)(ding)在(zai)分度(du)(du)(du)(du)頭(tou)上(shang),見(jian) 調整(zheng)分度(du)(du)(du)(du)頭(tou)傾角,將(jiang)分度(du)(du)(du)(du)頭(tou)扳起一個角度(du)(du)(du)(du),該角度(du)(du)(du)(du)等于(yu)錐(zhui)齒(chi)(chi)輪根錐(zhui)角δf,用(yong)切(qie)(qie)痕法使銑(xian)(xian)刀廓形 的(de)(de)對(dui)稱線(xian)對(dui)準齒(chi)(chi)坯的(de)(de)中(zhong)(zhong)心(xin),調整(zheng)切(qie)(qie)削(xue)深(shen)度(du)(du)(du)(du),以(yi)大(da)端為基準,將(jiang)工(gong)作臺升(sheng)高一個大(da)端全齒(chi)(chi)高后(hou),先銑(xian)(xian)齒(chi)(chi) 槽(cao)的(de)(de)中(zhong)(zhong)部,由(you)于(yu)此(ci)時采用(yong)的(de)(de)直齒(chi)(chi)錐(zhui)齒(chi)(chi)輪成形銑(xian)(xian)刀的(de)(de)厚度(du)(du)(du)(du)是按(an)照略小(xiao)于(yu)錐(zhui)齒(chi)(chi)輪小(xiao)端的(de)(de)齒(chi)(chi)槽(cao)寬度(du)(du)(du)(du)設計的(de)(de), 所(suo)以(yi)齒(chi)(chi)槽(cao)中(zhong)(zhong)部銑(xian)(xian)好后(hou),齒(chi)(chi)輪大(da)端和兩側面還(huan)有(you)一定(ding)(ding)加工(gong)余量(liang),因此(ci),還(huan)要對(dui)上(shang)述部位進行加工(gong)。
此(ci)時, 將(jiang)分度頭底座在水平面(mian)旋轉(zhuan)一個α角(jiao)(jiao),使銑刀廓形對(dui)稱線和齒(chi)(chi)(chi)坯軸線成(cheng)一個角(jiao)(jiao)度,同時適當移動橫向(xiang) 工作臺(tai)(移動量可以通過試切來確(que)定),先將(jiang)齒(chi)(chi)(chi)槽一側(ce)的(de)余量銑去,然(ran)后(hou)再(zai)將(jiang)分度頭底座反向(xiang)旋 轉(zhuan)2α角(jiao)(jiao),橫向(xiang)工作臺(tai)也(ye)反向(xiang)移動,銑削齒(chi)(chi)(chi)槽的(de)另一側(ce)面(mian)余量。
