拖(tuo)泵銑齒(chi)方(fang)法和(he)工藝過(guo)程(cheng)
在普(pu)通臥式銑(xian)(xian)床上(shang),采用帶有(you)轉(zhuan)盤的(de)分度(du)(du)(du)頭進(jin)行分度(du)(du)(du)。具體方法(fa)是想將(jiang)(jiang)齒(chi)(chi)(chi)坯固定(ding)在分度(du)(du)(du)頭上(shang),見 調整(zheng)分度(du)(du)(du)頭傾角(jiao),將(jiang)(jiang)分度(du)(du)(du)頭扳起一(yi)個角(jiao)度(du)(du)(du),該(gai)角(jiao)度(du)(du)(du)等于錐齒(chi)(chi)(chi)輪(lun)根錐角(jiao)δf,用切(qie)痕法(fa)使銑(xian)(xian)刀廓形 的(de)對(dui)(dui)稱(cheng)線(xian)對(dui)(dui)準(zhun)(zhun)齒(chi)(chi)(chi)坯的(de)中(zhong)心(xin),調整(zheng)切(qie)削深度(du)(du)(du),以(yi)大(da)端(duan)(duan)(duan)為基準(zhun)(zhun),將(jiang)(jiang)工作臺(tai)升高一(yi)個大(da)端(duan)(duan)(duan)全齒(chi)(chi)(chi)高后,先銑(xian)(xian)齒(chi)(chi)(chi) 槽的(de)中(zhong)部,由于此(ci)時采用的(de)直齒(chi)(chi)(chi)錐齒(chi)(chi)(chi)輪(lun)成(cheng)形銑(xian)(xian)刀的(de)厚度(du)(du)(du)是按照略小于錐齒(chi)(chi)(chi)輪(lun)小端(duan)(duan)(duan)的(de)齒(chi)(chi)(chi)槽寬度(du)(du)(du)設計的(de), 所(suo)以(yi)齒(chi)(chi)(chi)槽中(zhong)部銑(xian)(xian)好后,齒(chi)(chi)(chi)輪(lun)大(da)端(duan)(duan)(duan)和兩側面還有(you)一(yi)定(ding)加工余量(liang),因此(ci),還要對(dui)(dui)上(shang)述部位進(jin)行加工。
此時, 將分(fen)度頭(tou)底座在水(shui)平(ping)面旋(xuan)轉(zhuan)一(yi)(yi)個α角(jiao),使銑(xian)刀廓形對稱線(xian)和齒(chi)(chi)坯(pi)軸線(xian)成(cheng)一(yi)(yi)個角(jiao)度,同(tong)時適當(dang)移動(dong)橫向(xiang)(xiang) 工作臺(移動(dong)量可以通過試切來確定),先將齒(chi)(chi)槽一(yi)(yi)側的余量銑(xian)去,然后再(zai)將分(fen)度頭(tou)底座反(fan)向(xiang)(xiang)旋(xuan) 轉(zhuan)2α角(jiao),橫向(xiang)(xiang)工作臺也(ye)反(fan)向(xiang)(xiang)移動(dong),銑(xian)削齒(chi)(chi)槽的另(ling)一(yi)(yi)側面余量。
