拖(tuo)泵銑齒方法和(he)工(gong)藝過程
在普(pu)通臥式銑(xian)(xian)床上(shang),采用帶有(you)(you)轉盤的分(fen)(fen)度(du)(du)(du)(du)頭(tou)進行(xing)分(fen)(fen)度(du)(du)(du)(du)。具體方法(fa)是想將齒(chi)(chi)(chi)坯(pi)(pi)固定(ding)在分(fen)(fen)度(du)(du)(du)(du)頭(tou)上(shang),見(jian) 調整分(fen)(fen)度(du)(du)(du)(du)頭(tou)傾角,將分(fen)(fen)度(du)(du)(du)(du)頭(tou)扳起一(yi)個角度(du)(du)(du)(du),該角度(du)(du)(du)(du)等于(yu)錐(zhui)齒(chi)(chi)(chi)輪(lun)(lun)(lun)根錐(zhui)角δf,用切(qie)痕(hen)法(fa)使銑(xian)(xian)刀廓形 的對(dui)稱線(xian)對(dui)準(zhun)齒(chi)(chi)(chi)坯(pi)(pi)的中(zhong)心,調整切(qie)削深度(du)(du)(du)(du),以大(da)端(duan)(duan)為基準(zhun),將工(gong)作臺升高一(yi)個大(da)端(duan)(duan)全齒(chi)(chi)(chi)高后(hou),先銑(xian)(xian)齒(chi)(chi)(chi) 槽(cao)的中(zhong)部,由(you)于(yu)此時采用的直齒(chi)(chi)(chi)錐(zhui)齒(chi)(chi)(chi)輪(lun)(lun)(lun)成形銑(xian)(xian)刀的厚度(du)(du)(du)(du)是按照略小于(yu)錐(zhui)齒(chi)(chi)(chi)輪(lun)(lun)(lun)小端(duan)(duan)的齒(chi)(chi)(chi)槽(cao)寬度(du)(du)(du)(du)設計的, 所(suo)以齒(chi)(chi)(chi)槽(cao)中(zhong)部銑(xian)(xian)好后(hou),齒(chi)(chi)(chi)輪(lun)(lun)(lun)大(da)端(duan)(duan)和兩(liang)側面(mian)還有(you)(you)一(yi)定(ding)加(jia)工(gong)余量,因(yin)此,還要(yao)對(dui)上(shang)述部位進行(xing)加(jia)工(gong)。
此時, 將分(fen)度(du)頭(tou)底座在水平面(mian)旋轉一(yi)個α角(jiao),使銑刀廓形對稱線(xian)和齒坯軸(zhou)線(xian)成一(yi)個角(jiao)度(du),同時適當移動(dong)(dong)橫向 工作臺(移動(dong)(dong)量(liang)可以通過試切(qie)來(lai)確定(ding)),先(xian)將齒槽一(yi)側的余量(liang)銑去,然后再將分(fen)度(du)頭(tou)底座反(fan)向旋 轉2α角(jiao),橫向工作臺也(ye)反(fan)向移動(dong)(dong),銑削齒槽的另一(yi)側面(mian)余量(liang)。
