具體參數
拖泵(beng)銑(xian)齒方(fang)法和工藝過程
在普通臥式銑(xian)(xian)(xian)床(chuang)上(shang),采用(yong)帶有轉盤的(de)(de)分(fen)(fen)度頭(tou)(tou)(tou)進行(xing)分(fen)(fen)度。具體方法是想將齒(chi)(chi)坯(pi)固定在分(fen)(fen)度頭(tou)(tou)(tou)上(shang),見 調整(zheng)分(fen)(fen)度頭(tou)(tou)(tou)傾(qing)角(jiao),將分(fen)(fen)度頭(tou)(tou)(tou)扳起一(yi)個角(jiao)度,該角(jiao)度等于(yu)錐(zhui)齒(chi)(chi)輪(lun)根錐(zhui)角(jiao)δf,用(yong)切(qie)痕法使銑(xian)(xian)(xian)刀廓形 的(de)(de)對稱線對準齒(chi)(chi)坯(pi)的(de)(de)中心,調整(zheng)切(qie)削(xue)深(shen)度,以大(da)端為基準,將工(gong)作(zuo)臺(tai)升高一(yi)個大(da)端全(quan)齒(chi)(chi)高后,先(xian)銑(xian)(xian)(xian)齒(chi)(chi) 槽(cao)(cao)的(de)(de)中部(bu),由于(yu)此時采用(yong)的(de)(de)直齒(chi)(chi)錐(zhui)齒(chi)(chi)輪(lun)成形銑(xian)(xian)(xian)刀的(de)(de)厚(hou)度是按(an)照略小于(yu)錐(zhui)齒(chi)(chi)輪(lun)小端的(de)(de)齒(chi)(chi)槽(cao)(cao)寬度設計的(de)(de), 所以齒(chi)(chi)槽(cao)(cao)中部(bu)銑(xian)(xian)(xian)好后,齒(chi)(chi)輪(lun)大(da)端和(he)兩側面還有一(yi)定加工(gong)余量,因此,還要對上(shang)述部(bu)位(wei)進行(xing)加工(gong)。
此時(shi), 將分度頭(tou)底(di)座在水平面旋轉(zhuan)一(yi)(yi)個(ge)α角(jiao)(jiao),使銑(xian)刀廓(kuo)形(xing)對稱線和齒(chi)坯軸線成一(yi)(yi)個(ge)角(jiao)(jiao)度,同(tong)時(shi)適當移(yi)動橫(heng)向 工(gong)(gong)作(zuo)臺(tai)(移(yi)動量可(ke)以通(tong)過試切來確定),先將齒(chi)槽(cao)一(yi)(yi)側的余(yu)(yu)量銑(xian)去,然后(hou)再將分度頭(tou)底(di)座反(fan)向旋 轉(zhuan)2α角(jiao)(jiao),橫(heng)向工(gong)(gong)作(zuo)臺(tai)也(ye)反(fan)向移(yi)動,銑(xian)削齒(chi)槽(cao)的另一(yi)(yi)側面余(yu)(yu)量。
