一、龍門加工中心是什么機械
加工中心的(de)種類有(you)很(hen)多(duo),龍門加(jia)工(gong)(gong)中(zhong)(zhong)心是(shi)其中(zhong)(zhong)一種,它是(shi)指主軸(zhou)Z軸(zhou)的(de)軸(zhou)線與工(gong)(gong)作(zuo)臺(tai)垂(chui)直設置(zhi)的(de)加(jia)工(gong)(gong)中(zhong)(zhong)心,整體結構(gou)是(shi)由雙立(li)柱和頂(ding)梁(liang)構(gou)成(cheng)門式結構(gou)框架(jia),雙立(li)柱中(zhong)(zhong)間(jian)還有(you)橫梁(liang)。
龍門加工(gong)(gong)(gong)中心由工(gong)(gong)(gong)作臺(tai)、龍門、滑枕、刀庫、附件(jian)(jian)頭庫和數控系統組成,有定(ding)梁(liang)(liang)式(橫梁(liang)(liang)固(gu)定(ding)、工(gong)(gong)(gong)作臺(tai)移(yi)動或轉動)、動梁(liang)(liang)式(橫梁(liang)(liang)上下移(yi)動、工(gong)(gong)(gong)作臺(tai)前后(hou)移(yi)動)、動柱式(工(gong)(gong)(gong)作臺(tai)固(gu)定(ding),龍門架(jia)移(yi)動)、天車式(工(gong)(gong)(gong)作臺(tai)固(gu)定(ding),橫梁(liang)(liang)移(yi)動)等多種,主要適(shi)用(yong)于加工(gong)(gong)(gong)大型工(gong)(gong)(gong)件(jian)(jian)和形(xing)狀復(fu)雜(za)的工(gong)(gong)(gong)件(jian)(jian)。
二、龍門加工中心和普通加工中心的區別是什么
龍門加(jia)工中(zhong)心(xin)屬于立式(shi)的加(jia)工中(zhong)心(xin),它(ta)和普通(tong)加(jia)工中(zhong)心(xin)相比,差(cha)別(bie)主要體現在:
1、結構方面,龍門(men)加(jia)工中心的(de)是(shi)X軸非常(chang)長,是(shi)雙立柱結構的(de),Y軸行程較普通加(jia)工中心增(zeng)大,而且還(huan)比普通加(jia)工中心多了(le)一(yi)個側銑頭
2、加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)范圍(wei)方(fang)面,龍門(men)(men)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)中心因有(you)雙立柱支撐,在重(zhong)切削時優勢明(ming)顯,因此可(ke)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)的工(gong)(gong)(gong)(gong)件(jian)比較大,一些(xie)比較大型(xing)或形狀較復雜的工(gong)(gong)(gong)(gong)件(jian)只能用龍門(men)(men)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)中心加(jia)(jia)(jia)工(gong)(gong)(gong)(gong),普通加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)中心處理不了。
3、尺寸方面,龍門加工中心通(tong)常要(yao)比(bi)普通(tong)的加工中心要(yao)大一些。
三、龍門加工中心是幾軸的
三、四、五軸都(dou)有(you)。
龍門加工中心是一種數控車床,一般用的比較多的是三軸的龍門加工中心,有X、Y、Z三個軸,不過也有的龍門加工中心是四(si)軸(zhou)(zhou)(zhou)的(de)(de),在(zai)三軸(zhou)(zhou)(zhou)的(de)(de)基礎上加(jia)了(le)一個旋轉(zhuan)軸(zhou)(zhou)(zhou),能完成工(gong)件的(de)(de)四(si)面(mian)加(jia)工(gong);一些加(jia)工(gong)要求較(jiao)高的(de)(de)也會(hui)用到五軸(zhou)(zhou)(zhou)龍門加(jia)工(gong)中(zhong)心,增加(jia)了(le)一個旋轉(zhuan)軸(zhou)(zhou)(zhou)和一個擺動軸(zhou)(zhou)(zhou),配合五軸(zhou)(zhou)(zhou)聯動的(de)(de)數控系統,還可以對復雜的(de)(de)空間曲面(mian)進行高精度(du)加(jia)工(gong)。
