拖泵銑齒方法和(he)工藝過程
在(zai)普(pu)通臥式銑(xian)床上,采用(yong)(yong)帶有轉盤的分度(du)(du)(du)(du)頭(tou)進(jin)行(xing)分度(du)(du)(du)(du)。具(ju)體方法(fa)是(shi)想(xiang)將齒(chi)(chi)(chi)(chi)坯固定在(zai)分度(du)(du)(du)(du)頭(tou)上,見 調(diao)整分度(du)(du)(du)(du)頭(tou)傾角(jiao)(jiao),將分度(du)(du)(du)(du)頭(tou)扳起一(yi)個角(jiao)(jiao)度(du)(du)(du)(du),該(gai)角(jiao)(jiao)度(du)(du)(du)(du)等(deng)于(yu)(yu)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)根錐(zhui)角(jiao)(jiao)δf,用(yong)(yong)切痕法(fa)使銑(xian)刀(dao)廓形 的對稱(cheng)線(xian)對準(zhun)齒(chi)(chi)(chi)(chi)坯的中(zhong)心,調(diao)整切削深度(du)(du)(du)(du),以(yi)大(da)端為基(ji)準(zhun),將工(gong)作臺升高(gao)(gao)一(yi)個大(da)端全齒(chi)(chi)(chi)(chi)高(gao)(gao)后(hou),先銑(xian)齒(chi)(chi)(chi)(chi) 槽的中(zhong)部(bu),由(you)于(yu)(yu)此時采用(yong)(yong)的直齒(chi)(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)成形銑(xian)刀(dao)的厚(hou)度(du)(du)(du)(du)是(shi)按照略小于(yu)(yu)錐(zhui)齒(chi)(chi)(chi)(chi)輪(lun)小端的齒(chi)(chi)(chi)(chi)槽寬度(du)(du)(du)(du)設計的, 所以(yi)齒(chi)(chi)(chi)(chi)槽中(zhong)部(bu)銑(xian)好后(hou),齒(chi)(chi)(chi)(chi)輪(lun)大(da)端和兩(liang)側(ce)面還(huan)(huan)有一(yi)定加工(gong)余量,因此,還(huan)(huan)要對上述部(bu)位進(jin)行(xing)加工(gong)。
此時, 將分度頭底(di)座在水平面旋(xuan)轉一個(ge)α角,使銑(xian)刀(dao)廓形對稱線和(he)齒坯軸線成一個(ge)角度,同時適(shi)當移(yi)動橫向 工作(zuo)臺(tai)(移(yi)動量(liang)可以通過試切來確定),先將齒槽一側的余(yu)量(liang)銑(xian)去,然后(hou)再將分度頭底(di)座反(fan)向旋(xuan) 轉2α角,橫向工作(zuo)臺(tai)也(ye)反(fan)向移(yi)動,銑(xian)削齒槽的另一側面余(yu)量(liang)。
