拖泵(beng)銑齒方法和工藝過(guo)程
在(zai)普通臥式銑(xian)(xian)床上(shang),采(cai)用帶有轉盤的分度(du)(du)(du)頭(tou)進行分度(du)(du)(du)。具體方法是(shi)想(xiang)將(jiang)齒(chi)(chi)(chi)坯(pi)固定在(zai)分度(du)(du)(du)頭(tou)上(shang),見 調(diao)整分度(du)(du)(du)頭(tou)傾角,將(jiang)分度(du)(du)(du)頭(tou)扳起一(yi)個(ge)角度(du)(du)(du),該角度(du)(du)(du)等于(yu)錐齒(chi)(chi)(chi)輪根錐角δf,用切痕法使銑(xian)(xian)刀廓形 的對(dui)稱線對(dui)準(zhun)齒(chi)(chi)(chi)坯(pi)的中(zhong)心(xin),調(diao)整切削(xue)深度(du)(du)(du),以大端為(wei)基準(zhun),將(jiang)工作臺升高一(yi)個(ge)大端全齒(chi)(chi)(chi)高后,先銑(xian)(xian)齒(chi)(chi)(chi) 槽的中(zhong)部,由于(yu)此時采(cai)用的直齒(chi)(chi)(chi)錐齒(chi)(chi)(chi)輪成形銑(xian)(xian)刀的厚度(du)(du)(du)是(shi)按照略(lve)小于(yu)錐齒(chi)(chi)(chi)輪小端的齒(chi)(chi)(chi)槽寬度(du)(du)(du)設計的, 所(suo)以齒(chi)(chi)(chi)槽中(zhong)部銑(xian)(xian)好后,齒(chi)(chi)(chi)輪大端和(he)兩側面還有一(yi)定加(jia)工余量,因此,還要對(dui)上(shang)述部位進行加(jia)工。
此時(shi), 將(jiang)分度(du)頭底(di)座在水(shui)平(ping)面旋(xuan)轉(zhuan)一(yi)(yi)個α角(jiao)(jiao),使銑(xian)刀廓(kuo)形(xing)對稱線和齒(chi)坯軸(zhou)線成一(yi)(yi)個角(jiao)(jiao)度(du),同時(shi)適當移動(dong)橫(heng)向(xiang)(xiang) 工作(zuo)臺(tai)(移動(dong)量(liang)可以通過試切來確定(ding)),先將(jiang)齒(chi)槽一(yi)(yi)側(ce)的余量(liang)銑(xian)去,然后(hou)再將(jiang)分度(du)頭底(di)座反向(xiang)(xiang)旋(xuan) 轉(zhuan)2α角(jiao)(jiao),橫(heng)向(xiang)(xiang)工作(zuo)臺(tai)也(ye)反向(xiang)(xiang)移動(dong),銑(xian)削齒(chi)槽的另一(yi)(yi)側(ce)面余量(liang)。
