拖泵銑齒方(fang)法(fa)和工(gong)藝(yi)過程
在普通臥式銑(xian)床上(shang),采(cai)(cai)用(yong)帶有(you)轉盤的(de)分(fen)度頭(tou)進行(xing)分(fen)度。具體方法是(shi)想將齒(chi)(chi)(chi)(chi)(chi)坯固定(ding)(ding)在分(fen)度頭(tou)上(shang),見 調整分(fen)度頭(tou)傾角(jiao),將分(fen)度頭(tou)扳(ban)起一個角(jiao)度,該(gai)角(jiao)度等于(yu)(yu)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)根錐(zhui)(zhui)(zhui)角(jiao)δf,用(yong)切(qie)痕(hen)法使(shi)銑(xian)刀廓形(xing)(xing) 的(de)對(dui)稱(cheng)線對(dui)準齒(chi)(chi)(chi)(chi)(chi)坯的(de)中(zhong)心(xin),調整切(qie)削深(shen)度,以(yi)大端(duan)為基(ji)準,將工(gong)作臺(tai)升高(gao)一個大端(duan)全齒(chi)(chi)(chi)(chi)(chi)高(gao)后,先銑(xian)齒(chi)(chi)(chi)(chi)(chi) 槽的(de)中(zhong)部(bu),由于(yu)(yu)此時(shi)采(cai)(cai)用(yong)的(de)直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)成形(xing)(xing)銑(xian)刀的(de)厚度是(shi)按照略小(xiao)于(yu)(yu)錐(zhui)(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)小(xiao)端(duan)的(de)齒(chi)(chi)(chi)(chi)(chi)槽寬度設計(ji)的(de), 所以(yi)齒(chi)(chi)(chi)(chi)(chi)槽中(zhong)部(bu)銑(xian)好后,齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)大端(duan)和(he)兩側面還(huan)有(you)一定(ding)(ding)加工(gong)余量,因此,還(huan)要對(dui)上(shang)述部(bu)位進行(xing)加工(gong)。
此時, 將(jiang)分度頭(tou)底座在水平面(mian)旋轉(zhuan)一個(ge)α角(jiao),使銑刀廓形對稱線(xian)和齒坯(pi)軸線(xian)成一個(ge)角(jiao)度,同時適當移動橫向(xiang) 工作(zuo)臺(移動量可以通過試(shi)切來確定),先將(jiang)齒槽一側的余(yu)(yu)量銑去,然后再將(jiang)分度頭(tou)底座反向(xiang)旋 轉(zhuan)2α角(jiao),橫向(xiang)工作(zuo)臺也反向(xiang)移動,銑削齒槽的另一側面(mian)余(yu)(yu)量。
