1、數(shù)控機床副主軸設(shè)計原理摘要隨著我過國民經(jīng)濟的快速發(fā)展,數(shù)控機床在國內(nèi)的應(yīng)用越來越普遍,數(shù)控機床作為高效率自動化裝備越來越廣大應(yīng)用,數(shù)控技術(shù)是集計算機技術(shù),自動控制技術(shù),測試控制技術(shù),機械知道技術(shù)為一體的綜合性高新技術(shù),它將機械裝備的功能,可靠性,效率,質(zhì)量及自動化程度等提高到一個新的水平。數(shù)控機床的組成不見大致可以分為機械和電氣兩部分,機械部分通常稱為機床本體,它由對主軸組件的主運動系統(tǒng),進給系統(tǒng),支撐系統(tǒng)和自動換刀系統(tǒng)組成。副主軸組件由副主軸,副主軸軸承和安裝在主軸的傳動件,密封件等組成。它直接帶動工件或刀具參加表成形運動是機床上的一個關(guān)鍵組件。副主軸組件是機床主
2、要部件之一,它的性能,對整機性能有很大的影響,副主軸直接承受切削力,速度范圍很大,所以對副主軸組件的主要性能提出很高的要求。在數(shù)控機床中,不論是數(shù)控車床、鉆床還是銑床,其主軸是最關(guān)鍵的部件,對機床精度起著至關(guān)重要的作用。因此如何正確地設(shè)計機床副主軸及其組件對機床加工精度的影響是至關(guān)重要的。關(guān)鍵字:PrincipleABSTRACTWiththenationaleconomy,IhavetherapiddevelopmentofCNCmachinetoolsinChinaincreasingapplication,CNCmachinetoolsasanefficien
