2、　關鍵詞：組合機床;輪轂;設計;研制</p><p>　　四工位組合機床用于對載重汽車前、中后輪轂10-27+0.033孔的鉆、擴、鉸加工。此類機床過去已有的設備相對落后，電氣系統(tǒng)、液壓系統(tǒng)及機床主要部件相對過時和陳舊。本文介紹的組合機床有較先進的電氣控制系統(tǒng)和液壓系統(tǒng)，機床的運行采用三菱可編程控制器程序控制，程序可根據加工流程圖進行調整，變成方便靈活。它集粗鉆、擴加工和精鉸加用于一身，自成體系地形成一條圓形加工

3、流水線。該設備占地面積小，加工精度高，性能穩(wěn)定可靠，是汽車制造工廠加工輪轂不可多得的設備。它是由專用底座，專用主軸箱，專用夾具及鉆模板，THL86立柱，HY80系列滑臺及TD80A動力頭，AHY125A回轉工作臺等組成。</p><p>　?。?組合機床的技術發(fā)展</p><p><b>　　1.1 組合機床</b></p><p>　　組合機

4、床是一種專用高效自動化技術裝備，目前，由于它仍是大批量機械產品實現高效、高質量和經濟性生產的關鍵設備，因而被廣泛應用于汽車、拖拉機、內燃機和壓縮機等許多工業(yè)生產領域。所以說組合機床的技術性能和綜合自動化水平，在很大程度上決定了這些工業(yè)部門產品的生產效率、產品質量和企業(yè)生產組織的結構，也很大程度上決定了企業(yè)產品的競爭力。</p><p>　　現在組合機床作為機電一體化產品，它是控制、驅動、測量、監(jiān)控、刀具和機械組建

5、等技術的綜合反映。近２０年來，這些技術有長足進步，同時作為組合機床組要用戶的汽車和內燃機等行業(yè)也有很大的變化，其產品市場壽命不斷縮短，品種日益增多且質量不斷提高。這些因素有力地推動和激勵了組合機床的不斷發(fā)展。</p><p>　　1.2 組合機床品種的發(fā)展</p><p>　　在組合機床這類專用機床中,回轉式多工位組合機床和自動線占有很重要的地位。因為這兩類機床可以把工件的許多加工工序分配

6、到多個加工工位上,并同時能從多個方向對工件的幾個面進行加工,此外,還可以通過轉位夾具(在回轉工作臺機床上) 或通過轉位、翻轉裝置(在自動線上) 實現工件的五面加工或全部加工,因而具有很高的自動化程度和生產效率,被汽車、摩托車和壓縮機等工業(yè)部門所采用。</p><p>　　根據有關統(tǒng)計資料,德國在1990～1992 年期間,回轉式多工位組合機床和自動線的產量約各占組合機床總數的50 % 左右。應指出,回轉式多工位組

7、合機床實際上是一種特殊型式的小型自動線, 適合于加工輪廓尺寸≤ 250mm 的中小件。與自動線相比, 在加工同一種工件的情況下,回轉式多工位組合機床所占作業(yè)面積要比自動線約小2/ 3 。</p><p>　　1.3 組合機床柔性化進展迅速</p><p>　　十多年來,作為組合機床重要用戶的汽車工業(yè),為迎合人們個性化需求,汽車變型品種日益增多,以多品種展開競爭已成為汽車市場競爭的特點之一,

8、這使組合機床制造業(yè)面臨著變型多品種生產的挑戰(zhàn)。為適應多品種生產,傳統(tǒng)以加工單一品種的剛性組合機床和自動線必須提高其柔性。在70 年代,數控系統(tǒng)的可靠性有了很大的提高,故到70 年代末和80 年代初,像Alfing 、Hüller2 的運動特性曲線。由于電液比例閥控制系統(tǒng)Hille 和Ex2cell2o 等公司相繼開發(fā)出數控加工模塊和柔性自動線(F TL) ,從此數控組合機床和柔性自動線逐年增多。在1988 年至1992 年間,

9、日本組合機床和自動線(包括部分其它形式的專用機床) 產量的數控化率已達32 % ～39 % , 產值數控比率達35 %～ 51 % ; 德國組合機床和自動線產量的數控化，發(fā)動機變型品種日益增多的趨向率為18 %～62 % , 產值數控化率達45 %～66 %</p><p>　?。?四工位組合機床的設計</p><p>　?。?1 工藝方案的確定</p><p>　

10、　組合機床是針對某種零件或某道工工序而設計的，工藝方案又是組合機床設計的關鍵，它是根據被加工零件的結構特點、加工部位、加工的尺寸精度、粗糙度以及其他技術要求來確定設計的。</p><p>　　被加工件是汽車輪轂零件，在前道立車工序上已加工出280-0.1的定位圓，要求在375的圓周面上加工出10個27+0.033的孔，其位置公差為0～0.12，粗糙度為3.2。根據以上要求，工藝方案應確定粗精加工分開進行，即先鉆2

11、5的孔，然后擴孔到26.6，再精餃孔到27，考慮到零件的加工精度和工序集中原則，粗精加工合并成一道工序在一臺機床上進行。由此確定機床的鉆、擴、鉸三個工位，加之裝卸工件工位，故命名為四工位組合機床。</p><p>　?。?2 配置型式及其結構方案</p><p>　　機床的配置型式主要取決于被加工零件的加工精度和工藝方案，既要考慮能實現工藝方案以保證零件的加工精度、技術要求和生產效率；又要

12、考慮操作方便，易于維修，冷卻和排屑情況良好。該機床的配置型式屬于大型組合機床，總重量約為21t，總功率17.5kW四套專用夾具安裝在直徑1250m的回轉工作臺上，形成四個工位，與之對應的立柱上安裝HY80標準滑臺，滑臺上安裝標準動力頭和專用主軸箱，主軸箱的加工中心與回轉工作臺的回轉中心對中，成垂直立式布局。裝卸工件和加工工件可同時進行，互不干擾，既機床的切削時間和輔助時間重合，從而提高機床的工作效率。</p><p&

13、gt;　　３ 組合機床的主要組成部分</p><p><b>　?。?1 床身</b></p><p>　　床身部件必須有足夠的承載能力和足夠的剛度動態(tài)性能及過載儲備稀疏，以保證各部件之間能長期保持其正確的相對位置。組合機床的剛度和部件之間的精度保持性要由床身部件來保證。本機床的床身不見主要由回轉工作臺底座、立座底座、立柱和立柱墊等構成。它們起著組合機床的基礎骨架作用

14、。床身部件包括配重在內的重量達組合機床總重量的70%以上，因而具有良好的剛性和抗振性能，為保證機床的加工精度奠定了良好的基礎。</p><p><b>　?。?2 滑臺</b></p><p>　　滑臺之用來實現進給運動的動力部件，它主要由滑臺，滑臺座和液壓油缸三部分組成。滑臺座固定在立柱上，液壓油缸體固定在滑座上，活塞桿與滑臺相互連接，工作時，液壓油缸固定，活塞桿帶

15、著滑臺在滑座的導軌上作往返運動。本機床液壓滑臺屬于大型滑臺，有足夠的能量儲備?；_的工作有快進、共進和快退三種狀態(tài)。其動作是由電氣系統(tǒng)和液壓系統(tǒng)共同控制的。在滑臺上安裝有動力頭和主軸箱，滑臺頂部裝有鋼絲繩滑輪組，另一端在立柱中裝有配重塊，目的是使滑臺在滑座上移動輕便，并可防止滑臺端過重而下滑。</p><p>　?。?3 動力頭及主軸箱</p><p>　　動力頭是主軸運動的驅動裝置，它帶

16、動主軸箱的各個輸出主軸使刀具作主體運動。本機床鉆、擴、餃孔刀具直徑分別為25mm、26.6mm和27mm，被加工零件材料為35CrMoV，硬度HRC28～32，考慮到扭矩儲備系數，機床采用標準TD80A型動力頭，主電機為15KW。轉速為970r/min，輸出軸轉速為475r/min。主軸箱是組合機床重要部件之一，其作用是根據被加工件的加工要求，安排各主軸的位置，并將電機的動力按不同的轉速比輸出分配給各工作主軸，使主軸得到要求的轉速和轉向

17、，以滿足對零件的加工。主軸箱主軸的排列根據被加工零件的工藝要求進行設計，并與回轉工作臺上的夾具工位向對應，主軸箱的傳動齒輪及傳動軸可選標準件。</p><p>　?。?4 主軸及鉆模板</p><p>　　主軸的結構取決于零件的加工工藝以及主軸的受力情況。對于鉆削加工的主軸，受軸向切削力較大，應采用推力球軸承或滾錐軸承定位。主軸與刀具的連接方式采用莫氏3#導向套接桿，刀具的長短比例可視加工

18、情況調整接桿。用于鉆、擴孔加工的主軸轉速為175r/min。切削速度V=13.7m/min,進刀量S=0.17mm/r.鉸孔加工的主軸轉速為50r/min，切削速度V=4.24m/min，進刀量S=0.6mm/r，進刀速度Sv=30mm/min。鉆模板主要起對刀具的輔助定位作用，防止刀具在加工時擺動，從而提高被加工件的精度。</p><p><b>　?。?5 回轉工作臺</b></p

20、相互嚙合的端面齒輪，靠圓周多齒嚙合定位，具有定位精度高和剛性好的特點，所以在轉臺上無論徑向力、軸向力或切向力，都可以起到自動定心的作用。</p><p><b>　?。?6 夾具</b></p><p>　　夾具使用來防止并固定被加工零件的。正確選擇加工用定位基準是確保加工精度的重要條件。夾具的尺寸精度和安裝精度的高低直接影響到零件的加工精度，本機床共有四套尺寸相同的

21、夾具，均布在回轉工作臺上并與回轉臺中心形成同心圓流水線。夾具主要有四個夾具體、定位圈、夾緊油缸等組成。每套夾具有四個夾緊油缸，等分固定在夾具體的四個方向上，夾緊工件時受力均衡，防止零件變形。定位圈時夾具的關鍵部件，必須使四套夾具的定位圈尺寸公差相一致，而且四套夾具的回轉中心與回轉工作臺的回轉中心也應絕對重合，才能保證零件的加工精度。</p><p><b>　　３.7 液壓系統(tǒng)</b><

22、;/p><p>　　機床的液壓系統(tǒng)相當于人體的血液喜歡系統(tǒng)，被加工零件的夾緊、放松，工作臺的抬起、旋轉和落下，動力頭滑臺的快進、共進和快退等都是靠液壓系統(tǒng)來實現。液壓系統(tǒng)主要由液壓站集中控制，液壓電機為22KW，液壓泵為變量葉片泵，滑臺的動作是由一個三位五通電磁閥和調速閥來控制?；剞D工作臺的抬起、落下、回轉和復位，以及工件的夾緊和放松，主要由三個兩位四通電磁閥來控制。另外專設一路由程序控制的對液壓滑臺自動定時潤滑。&

24、定時和計數的控制，可以容易地實現機、電、液一體化。電氣系統(tǒng)的交流在、輸出控制主要有主軸電機，液壓電機，冷卻電機。直流輸出主要控制液壓站的十路電磁閥。</p><p>　　電氣系統(tǒng)的硬件主要有可編程控制器、變壓器、接觸器、操縱按鈕和保險器、整流二極管和續(xù)流二極管、以及行程開關等組成；軟件主要包括主程序，同時有為程序服務的各個期間的輸入輸出地址標和程序梯形圖等。</p><p>　　機床的操作

25、分調整和自動兩種方式，調整方式為手動控制機床的單步操作；自動方式由程序控制按加工流程圖實現自動循環(huán)。</p><p><b>　?。?9 冷卻系統(tǒng)</b></p><p>　　機床外部設有專用的帶腳輪的冷卻箱，便于維修和清理，冷卻泵電機為0.12KW。容量為50L/min，冷卻水到達鉆模板后分成三路，每一路有10個導向水嘴，對應于10把刀具，俄有效地實現刀具的冷卻。冷

26、卻泵在滑臺工進時由程序控制自動啟動，實施對被加工工件的冷卻，工進到終點時自動關閉。</p><p>　　4 組合機床的安裝調試及精度檢驗</p><p>　　在組裝過程中始終貫穿著對系統(tǒng)部件的不斷調試，以及對影響加工尺寸的主要部件的自身精度和結合精度進行調整。</p><p>　　系統(tǒng)的調試是根據各個系統(tǒng)的要求和機床工作循環(huán)圖的要求來對電氣系統(tǒng)、液壓系統(tǒng)、冷卻系統(tǒng)、
