直角(jiao)銑(xian)頭的功(gong)用：  

直(zhi)角銑(xian)頭(tou)(tou)的功用：銑(xian)頭(tou)(tou)是(shi)機(ji)(ji)床常用的附件，也是(shi)機(ji)(ji)床zui、技術含量(liang)zui高的部(bu)件之(zhi)一。一般機(ji)(ji)械萬(wan)s能銑(xian)頭(tou)(tou)可(ke)(ke)以大(da)大(da)擴(kuo)張機(ji)(ji)床的加工(gong)能力，可(ke)(ke)以完成任意角度頭(tou)(tou)斜面的銑(xian)削(xue)、鉆(zhan)孔、攻絲等加工(gong)；五軸(zhou)聯動加工(gong)的萬(wan)w能銑(xian)頭(tou)(tou)，可(ke)(ke)以用來加工(gong)航(hang)空航(hang)天(tian)、、核能、能源領(ling)域的關鍵零(ling)部(bu)件，如(ru)飛(fei)機(ji)(ji)發動機(ji)(ji)的葉片、火電汽輪機(ji)(ji)葉片、核潛艇(ting)螺旋(xuan)槳(jiang)等；

直角銑(xian)頭(tou)  

幾何原本中的定義：當一(yi)條直(zhi)線(xian)和另(ling)(ling)一(yi)條橫的直(zhi)線(xian)交成的鄰(lin)角彼(bi)此相等時，這些角的每(mei)一(yi)個(ge)被叫做直(zhi)角，而且稱這一(yi)條直(zhi)線(xian)垂直(zhi)于另(ling)(ling)一(yi)條直(zhi)線(xian)。  

一個(ge)直角等(deng)于90度(du).  

當兩條(tiao)線(xian)的夾(jia)角是直(zhi)角，這兩條(tiao)線(xian)便是互相(xiang)垂直(zhi)，是幾何上的一(yi)個(ge)(ge)重(zhong)要性質。而一(yi)個(ge)(ge)三(san)角形(xing)的其中一(yi)個(ge)(ge)內角為90°時，便稱為直(zhi)角三(san)角形(xing)，是應用(yong)畢氏定理(li)的先(xian)決條(tiao)件(jian)。

直角銑頭是(shi)一種重要(yao)的機床主軸附件

直(zhi)角(jiao)銑(xian)頭是一(yi)種重(zhong)要的(de)機床(chuang)主軸(zhou)附件，因其(qi)能夠使刀(dao)具軸(zhou)線(xian)與(yu)主軸(zhou)軸(zhou)線(xian)成(cheng) 90°直(zhi)角(jiao)結構，所以通過與(yu)多軸(zhou)加(jia)(jia)工(gong)(gong)中(zhong)心的(de)配合能夠增加(jia)(jia)機床(chuang)的(de)加(jia)(jia)工(gong)(gong)范圍。由于(yu)直(zhi)角(jiao)銑(xian)頭的(de)刀(dao)具軸(zhou)線(xian)與(yu)主軸(zhou)軸(zhou)線(xian)位于(yu)不(bu)同方(fang)位，鏜(tang)銑(xian)動力頭哪家好，傳統五軸(zhou)數控(kong)加(jia)(jia)工(gong)(gong)中(zhong)的(de)刀(dao)尖點補償方(fang)式已(yi)不(bu)再適用(yong)(yong)于(yu)直(zhi)角(jiao)銑(xian)頭，因此需探(tan)索新的(de)途徑(jing)來(lai)實現直(zhi)角(jiao)銑(xian)頭的(de)五軸(zhou)加(jia)(jia)工(gong)(gong)。直(zhi)角(jiao)銑(xian)頭應用(yong)(yong)于(yu)五軸(zhou)加(jia)(jia)工(gong)(gong)時，存在控(kong)制器參數設置復雜，鏜(tang)銑(xian)動力頭供應商，數控(kong)編(bian)程難度大，加(jia)(jia)工(gong)(gong)過程操作(zuo)繁(fan)瑣等問(wen)題(ti)，嚴重(zhong)影響了直(zhi)角(jiao)銑(xian)頭的(de)利用(yong)(yong)率(lv)和(he)加(jia)(jia)工(gong)(gong)效率(lv)，并且存在新技術風險分(fen)析(xi)不(bu)到位，造成(cheng)質量問(wen)題(ti)的(de)隱患。

直(zhi)角(jiao)銑(xian)頭改變了主軸的輸(shu)出(chu)方向：

直角銑頭(tou)為(wei)特別附件，可裝置在(zai)數控(kong)鏜(tang)(tang)(tang)銑床(chuang)和(he)鏜(tang)(tang)(tang)銑加工(gong)基地上，以擴展數控(kong)鏜(tang)(tang)(tang)銑床(chuang)和(he)鏜(tang)(tang)(tang)銑加工(gong)基地的運用(yong)范圍。

直(zhi)角銑頭選用合(he)金鋼制(zhi)作(zuo)，鏜銑動力頭，并在視點頭兩側邊磨削了(le)基準面(mian)，便利進行視點頭的(de)裝置調試時的(de)測定基準面(mian)。

直角銑頭(tou)的(de)刀柄銜接(jie)方(fang)法的(de)視點(dian)頭(tou)，可(ke)以完成視點(dian)頭(tou)的(de)主(zhu)動換刀。法蘭銜接(jie)方(fang)法的(de)也(ye)只(zhi)需依照機床(chuang)的(de)主(zhu)軸(zhou)鼻端方(fang)法做出呼應的(de)連接(jie)盤和法蘭，即可(ke)疾速裝置(zhi)。

直角銑(xian)頭(tou)(tou)的(de)(de)視點(dian)(dian)頭(tou)(tou)選用磨削齒輪和(he)高精密(mi)軸承制(zhi)作并(bing)選用持久潤滑(hua)，高可靠性(xing)的(de)(de)試驗，保證視點(dian)(dian)頭(tou)(tou)的(de)(de)精度(du)和(he)運(yun)用壽命。

因為(wei)改變了(le)主軸(zhou)的輸(shu)出方向，可以(yi)變相(xiang)的完成(cheng)機(ji)床(chuang)的五(wu)面(mian)加工，擴展了(le)機(ji)床(chuang)的功用。

直角銑(xian)頭(tou)的裝置(zhi)(zhi)方法也是很簡單的，只需在機床主軸端面(mian)裝置(zhi)(zhi)視(shi)點頭(tou)定(ding)位(wei)所需的定(ding)位(wei)塊即可(ke)完成(cheng)視(shi)點頭(tou)的運用(yong)。

直角(jiao)銑(xian)頭(tou)也叫橫向銑(xian)頭(tou)或(huo)臥式銑(xian)頭(tou)， 是指刀(dao)具輸出軸平行于(yu)水平面的銑(xian)頭(tou)。直角(jiao)銑(xian)頭(tou)可以實現立式加工(gong)(gong)中心的立臥轉換， 用(yong)于(yu)工(gong)(gong)件的側面加工(gong)(gong)，減少了工(gong)(gong)件的裝夾次數，大(da)大(da)提高了加工(gong)(gong)精度。

萬向銑頭具可換性

萬向銑(xian)頭(tou)主要為擴大鏜床(chuang)在實際工(gong)作中的(de)加(jia)工(gong)范(fan)圍，即沒有銑(xian)頭(tou)只可加(jia)工(gong)一個工(gong)位，到安裝銑(xian)頭(tou)一次性可加(jia)工(gong)到8個工(gong)位，并且主軸可伸展100-150毫米。下(xia)面是(shi)銑(xian)頭(tou)的(de)加(jia)工(gong)過(guo)程。

①操(cao)作(zuo)者(zhe)將要(yao)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)的(de)(de)零件(jian)放在工(gong)(gong)(gong)(gong)(gong)件(jian)臺的(de)(de)夾具(ju)中(zhong)，在其它準(zhun)備工(gong)(gong)(gong)(gong)(gong)作(zuo)就緒后，發出(chu)加(jia)(jia)(jia) 工(gong)(gong)(gong)(gong)(gong)指令。 ②工(gong)(gong)(gong)(gong)(gong)件(jian)夾緊后壓力繼(ji)電器動(dong)作(zuo)， 液壓動(dong)力滑(hua)臺 （工(gong)(gong)(gong)(gong)(gong)作(zuo)臺） 開(kai)始快進， 到位(wei)轉工(gong)(gong)(gong)(gong)(gong)進， 同時啟動(dong)左和右 1 銑頭(tou)開(kai)始加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)，加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)到某一位(wei)置(zhi)，立銑頭(tou)開(kai)始加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)，加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)又過(guo) 一定位(wei)置(zhi)右 1 銑頭(tou)停止(zhi)(zhi)，右 2 萬向銑頭(tou)開(kai)始加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)，加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)到終點三臺電動(dong)機同時停止(zhi)(zhi)。 ③待加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)完全停止(zhi)(zhi)后，滑(hua)臺快退回原位(wei)，鏜銑動(dong)力頭(tou)價格，工(gong)(gong)(gong)(gong)(gong)件(jian)松開(kai)，一個自動(dong)工(gong)(gong)(gong)(gong)(gong)作(zuo)循環(huan)結束。 ④操(cao)作(zuo)者(zhe)取下加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)好(hao)的(de)(de)工(gong)(gong)(gong)(gong)(gong)件(jian)，再放上(shang)未加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)的(de)(de)零件(jian)，重新(xin)發出(chu)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)指令重復(fu)上(shang)述 加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)過(guo)程(cheng)。

萬向銑頭主(zhu)軸(zhou)箱(xiang)(xiang)采(cai)用樹脂砂造型的(de)(de)高強度(du)鑄鐵以(yi)及(ji)合(he)理(li)的(de)(de)不筋結構，剛性(xing)好(hao)、穩定性(xing)強。工作臺拖動采(cai)用大慣量交流(liu)伺服電機、配置滾珠絲杠和重載直線導軌，經優化設計擁有良好(hao)的(de)(de)定位精度(du)及(ji)穩態響(xiang)應特性(xing)。主(zhu)運(yun)動采(cai)用寬(kuan)調速交流(liu)伺服主(zhu)電機、減速箱(xiang)(xiang)，使得主(zhu)軸(zhou)在(zai)低速時大扭矩輸出，萬向銑頭適合(he)重切削(xue)，高轉速時的(de)(de)恒功(gong)率適合(he)精加工。
