拖(tuo)泵銑(xian)齒方(fang)法和工(gong)藝過程
在普通(tong)臥(wo)式銑(xian)床(chuang)上(shang),采用(yong)帶有轉盤的分度(du)(du)(du)(du)(du)頭(tou)進(jin)行分度(du)(du)(du)(du)(du)。具體方法是(shi)想將(jiang)齒(chi)(chi)(chi)(chi)坯固定在分度(du)(du)(du)(du)(du)頭(tou)上(shang),見 調整分度(du)(du)(du)(du)(du)頭(tou)傾(qing)角(jiao),將(jiang)分度(du)(du)(du)(du)(du)頭(tou)扳起(qi)一(yi)個角(jiao)度(du)(du)(du)(du)(du),該角(jiao)度(du)(du)(du)(du)(du)等于(yu)錐齒(chi)(chi)(chi)(chi)輪根錐角(jiao)δf,用(yong)切痕法使銑(xian)刀(dao)(dao)廓形 的對稱線對準齒(chi)(chi)(chi)(chi)坯的中(zhong)心,調整切削深度(du)(du)(du)(du)(du),以大端為基準,將(jiang)工作臺升高一(yi)個大端全(quan)齒(chi)(chi)(chi)(chi)高后,先銑(xian)齒(chi)(chi)(chi)(chi) 槽(cao)的中(zhong)部,由于(yu)此時(shi)采用(yong)的直齒(chi)(chi)(chi)(chi)錐齒(chi)(chi)(chi)(chi)輪成形銑(xian)刀(dao)(dao)的厚(hou)度(du)(du)(du)(du)(du)是(shi)按照略小于(yu)錐齒(chi)(chi)(chi)(chi)輪小端的齒(chi)(chi)(chi)(chi)槽(cao)寬(kuan)度(du)(du)(du)(du)(du)設計的, 所(suo)以齒(chi)(chi)(chi)(chi)槽(cao)中(zhong)部銑(xian)好(hao)后,齒(chi)(chi)(chi)(chi)輪大端和兩側面還(huan)有一(yi)定加工余量,因(yin)此,還(huan)要對上(shang)述部位進(jin)行加工。
此時, 將(jiang)分度頭底座在水平面(mian)旋轉(zhuan)一個(ge)α角(jiao),使(shi)銑刀廓形(xing)對稱線和齒(chi)(chi)坯軸線成一個(ge)角(jiao)度,同時適當移動橫向(xiang) 工作臺(tai)(移動量(liang)可以通過試切來確定(ding)),先將(jiang)齒(chi)(chi)槽(cao)一側的余量(liang)銑去,然后(hou)再將(jiang)分度頭底座反向(xiang)旋 轉(zhuan)2α角(jiao),橫向(xiang)工作臺(tai)也(ye)反向(xiang)移動,銑削齒(chi)(chi)槽(cao)的另(ling)一側面(mian)余量(liang)。
