拖泵銑齒方法和工藝過程
在(zai)普通(tong)臥式銑(xian)(xian)(xian)床(chuang)上(shang),采(cai)用帶(dai)有轉盤的(de)(de)分度(du)(du)頭(tou)進行(xing)分度(du)(du)。具體(ti)方法是想將(jiang)(jiang)齒(chi)(chi)(chi)(chi)(chi)坯固定在(zai)分度(du)(du)頭(tou)上(shang),見(jian) 調整分度(du)(du)頭(tou)傾(qing)角,將(jiang)(jiang)分度(du)(du)頭(tou)扳起一(yi)個(ge)(ge)角度(du)(du),該角度(du)(du)等于(yu)錐(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)根錐(zhui)(zhui)角δf,用切(qie)(qie)痕法使銑(xian)(xian)(xian)刀廓形(xing) 的(de)(de)對稱線對準(zhun)齒(chi)(chi)(chi)(chi)(chi)坯的(de)(de)中心,調整切(qie)(qie)削(xue)深(shen)度(du)(du),以大(da)端為基準(zhun),將(jiang)(jiang)工作臺(tai)升高一(yi)個(ge)(ge)大(da)端全(quan)齒(chi)(chi)(chi)(chi)(chi)高后(hou),先銑(xian)(xian)(xian)齒(chi)(chi)(chi)(chi)(chi) 槽的(de)(de)中部(bu),由于(yu)此時采(cai)用的(de)(de)直齒(chi)(chi)(chi)(chi)(chi)錐(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)成形(xing)銑(xian)(xian)(xian)刀的(de)(de)厚度(du)(du)是按照略小(xiao)(xiao)于(yu)錐(zhui)(zhui)齒(chi)(chi)(chi)(chi)(chi)輪(lun)小(xiao)(xiao)端的(de)(de)齒(chi)(chi)(chi)(chi)(chi)槽寬度(du)(du)設計的(de)(de), 所以齒(chi)(chi)(chi)(chi)(chi)槽中部(bu)銑(xian)(xian)(xian)好后(hou),齒(chi)(chi)(chi)(chi)(chi)輪(lun)大(da)端和兩側面還(huan)(huan)有一(yi)定加(jia)工余量,因(yin)此,還(huan)(huan)要對上(shang)述部(bu)位進行(xing)加(jia)工。
此(ci)時, 將分度頭底座(zuo)在水平面旋轉一個(ge)α角,使(shi)銑刀廓形對(dui)稱線和齒坯(pi)軸線成(cheng)一個(ge)角度,同時適當(dang)移動橫(heng)向(xiang) 工作(zuo)臺(移動量可(ke)以通過試(shi)切來確定),先將齒槽一側的余(yu)(yu)量銑去,然后再將分度頭底座(zuo)反向(xiang)旋 轉2α角,橫(heng)向(xiang)工作(zuo)臺也反向(xiang)移動,銑削齒槽的另一側面余(yu)(yu)量。
