拖泵銑齒方法(fa)和工藝過程
在普通臥式銑(xian)(xian)床上,采(cai)用(yong)(yong)帶有(you)轉盤的(de)分(fen)(fen)度(du)(du)頭(tou)進行分(fen)(fen)度(du)(du)。具體方法(fa)是(shi)想(xiang)將(jiang)齒(chi)(chi)(chi)坯(pi)(pi)固定(ding)在分(fen)(fen)度(du)(du)頭(tou)上,見 調整分(fen)(fen)度(du)(du)頭(tou)傾(qing)角(jiao),將(jiang)分(fen)(fen)度(du)(du)頭(tou)扳起(qi)一個角(jiao)度(du)(du),該角(jiao)度(du)(du)等于錐(zhui)齒(chi)(chi)(chi)輪(lun)根錐(zhui)角(jiao)δf,用(yong)(yong)切痕法(fa)使銑(xian)(xian)刀廓形 的(de)對(dui)(dui)稱線對(dui)(dui)準齒(chi)(chi)(chi)坯(pi)(pi)的(de)中心,調整切削深度(du)(du),以大(da)端為(wei)基準,將(jiang)工(gong)作臺升高一個大(da)端全齒(chi)(chi)(chi)高后(hou),先銑(xian)(xian)齒(chi)(chi)(chi) 槽的(de)中部(bu),由于此時采(cai)用(yong)(yong)的(de)直齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪(lun)成形銑(xian)(xian)刀的(de)厚(hou)度(du)(du)是(shi)按照略小于錐(zhui)齒(chi)(chi)(chi)輪(lun)小端的(de)齒(chi)(chi)(chi)槽寬(kuan)度(du)(du)設計(ji)的(de), 所以齒(chi)(chi)(chi)槽中部(bu)銑(xian)(xian)好后(hou),齒(chi)(chi)(chi)輪(lun)大(da)端和兩側面還有(you)一定(ding)加工(gong)余量,因此,還要對(dui)(dui)上述部(bu)位(wei)進行加工(gong)。
此時, 將分度(du)頭(tou)(tou)底(di)座在水平面旋轉一(yi)個α角,使銑(xian)刀廓(kuo)形對稱(cheng)線和齒坯(pi)軸線成(cheng)一(yi)個角度(du),同時適當移動(dong)橫(heng)(heng)向 工(gong)作臺(移動(dong)量(liang)可以通過(guo)試切來確(que)定),先將齒槽一(yi)側的余(yu)量(liang)銑(xian)去,然后再將分度(du)頭(tou)(tou)底(di)座反向旋 轉2α角,橫(heng)(heng)向工(gong)作臺也反向移動(dong),銑(xian)削齒槽的另一(yi)側面余(yu)量(liang)。
