拖泵銑(xian)齒方法(fa)和工藝過程
在(zai)(zai)普通(tong)臥(wo)式銑(xian)(xian)(xian)床上(shang),采用(yong)帶有(you)轉盤的(de)分(fen)(fen)(fen)度(du)(du)頭(tou)(tou)進行分(fen)(fen)(fen)度(du)(du)。具體方(fang)法(fa)是想將(jiang)(jiang)齒(chi)(chi)(chi)坯固定在(zai)(zai)分(fen)(fen)(fen)度(du)(du)頭(tou)(tou)上(shang),見 調(diao)整分(fen)(fen)(fen)度(du)(du)頭(tou)(tou)傾(qing)角(jiao)(jiao),將(jiang)(jiang)分(fen)(fen)(fen)度(du)(du)頭(tou)(tou)扳起一(yi)個角(jiao)(jiao)度(du)(du),該(gai)角(jiao)(jiao)度(du)(du)等于(yu)錐(zhui)齒(chi)(chi)(chi)輪根錐(zhui)角(jiao)(jiao)δf,用(yong)切(qie)痕法(fa)使銑(xian)(xian)(xian)刀(dao)廓形(xing) 的(de)對稱線(xian)對準(zhun)齒(chi)(chi)(chi)坯的(de)中心,調(diao)整切(qie)削深度(du)(du),以大端(duan)為基準(zhun),將(jiang)(jiang)工作臺升(sheng)高一(yi)個大端(duan)全齒(chi)(chi)(chi)高后(hou),先銑(xian)(xian)(xian)齒(chi)(chi)(chi) 槽(cao)(cao)的(de)中部(bu)(bu),由于(yu)此(ci)時采用(yong)的(de)直齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪成形(xing)銑(xian)(xian)(xian)刀(dao)的(de)厚度(du)(du)是按照略(lve)小于(yu)錐(zhui)齒(chi)(chi)(chi)輪小端(duan)的(de)齒(chi)(chi)(chi)槽(cao)(cao)寬度(du)(du)設計的(de), 所以齒(chi)(chi)(chi)槽(cao)(cao)中部(bu)(bu)銑(xian)(xian)(xian)好(hao)后(hou),齒(chi)(chi)(chi)輪大端(duan)和兩側(ce)面還(huan)有(you)一(yi)定加工余量(liang),因此(ci),還(huan)要對上(shang)述部(bu)(bu)位進行加工。
此(ci)時, 將分度頭(tou)(tou)底(di)座(zuo)(zuo)在(zai)水平面(mian)旋轉(zhuan)一(yi)個α角,使銑(xian)刀廓形對稱線(xian)和齒坯軸線(xian)成一(yi)個角度,同(tong)時適當移(yi)動(dong)橫向 工(gong)作臺(移(yi)動(dong)量(liang)(liang)(liang)可(ke)以通(tong)過試(shi)切來確定),先將齒槽(cao)(cao)一(yi)側的余(yu)量(liang)(liang)(liang)銑(xian)去,然后(hou)再將分度頭(tou)(tou)底(di)座(zuo)(zuo)反(fan)向旋 轉(zhuan)2α角,橫向工(gong)作臺也反(fan)向移(yi)動(dong),銑(xian)削齒槽(cao)(cao)的另一(yi)側面(mian)余(yu)量(liang)(liang)(liang)。
