普通車床的自動化改造摘 要隨著當今工業(yè)設備對精密程度的要求越來越高，加工設備的機械加工設備的加工的精密程度也要求越來越高。而在中國的機械加工設備的車床中普通車床占了很大比例。這已經越來越制約著當今工業(yè)的發(fā)展。而數(shù)控機床由于價格昂貴，且需要較高技術的加工工人。所以對機床進行自動化改造很是必要。本篇論文是在對普通臥式車床 C6150 的基礎上對其進行自動化改造。作者在搜索、查閱研究大量有關資料的基礎上，對機床自動化改造技術進行了深入的研究和分析，并描述了機床控制系統(tǒng)的設計。整個改造過程主要對車床縱、橫向進給系統(tǒng)進行改造，選用自動轉位刀架，由脈沖發(fā)生器來加工所需要的螺紋。整個控制系統(tǒng)以 8031 型號的單片機為中心，通過編程對機床的驅動設備進行控制以達到所需要的加工程度。關鍵詞：機床改造； 自動化機床； 控制系統(tǒng)普通車床的自動化改造ABSTRACTWith the development of industry equipment, the precision required of industry equipment is more and more high. The more and more precision of equipment which machined the industry equipment is required. But in China the common lathe have a very great comparison in the machined equipment, this already restrict the development of industrial nowadays. But the CN lathe is more expensive, and needed workers with higher technically. So it is a necessity very much to modify the common lathe to lathes automatic. This paper is in the foundation of the commonness horizontal lather C6150 and modified it to Lathes automatic.The author has performed the further research and for the lathes automatic modification on the basis of the constant consultation of abundant relative documents, which focuses on describing the design of control of the machine. The main to modify the lathe is to modify the portrait, horizontal enter to the system in the Whole modification process and choose the automatic knife rest and be processed the thread need by pulser. The whole control system with the CPU of 8031 is to control the machine for center, through a plait distance drive tool machine an equipments to carry on control to attain need of process degree.Key words: Machinery Tool Reform； Lathes automatic； Servo system普通車床的自動化改造1目 錄第 1 章 緒論 ..................................................11.1 數(shù)控機床與數(shù)控技術 .......................................11.1.1 數(shù)控機床與發(fā)展趨勢 .................................11.1.2 數(shù)控技術 ...........................................21.1.3 數(shù)控技術發(fā)展趨勢 ...................................41.1.4 數(shù)控機床目前在工業(yè)中的地位 .........................61.2 數(shù)控改造的必要性 .........................................61.2.1 機床與生產線數(shù)控化改造的市場 .......................71.2.2 機床數(shù)控化改造的必要性 .............................71.3 數(shù)控化改造的內容及優(yōu)缺 ...................................81.4 對我國數(shù)控技術和產業(yè)化發(fā)展的戰(zhàn)略見解 ....................101.4.1 形勢考慮 ..........................................101.4.2 發(fā)展策略 ..........................................101.5 本文的選題及主要研究內容 ................................111.5.1 本文的選題 ........................................111.5.2 主要研究內容 ......................................11第 2 章 數(shù)控車床總體改造方案及機械部分設計 ...............132.1 設計要求 ................................................13普通車床的自動化改造22.1.1 設計基本思路 ......................................132.1.2 改造方案的確定 ....................................132.1.3 設計目的 ..........................................132.1.4 總體方案設計 ......................................152.2 滾珠絲杠的設計計算與選用 ................................152.2.1 滾珠絲杠 ..........................................152.2.2 縱向滾珠絲杠的設計與計算 ..........................162.2.3 橫向滾珠絲杠的設計與計算 ..........................242.2.4 滾珠絲杠的安裝與使用 ..............................322.3 電機與滾珠絲杠連接用一級減速齒輪的設計與校核 ............342.3.1 齒輪傳動 ..........................................342.3.2 縱向減速齒輪的設計與校核 ..........................352.3.3 橫向減速齒輪的設計與校核 ..........................392.4 進給系統(tǒng)的步進電動機的計算與選擇 ........................422.4.1 步進電動機 ........................................422.4.2 縱向電機的計算與選擇 ..............................442.4.3 橫向電機的計算與選擇 ..............................472.5 電動刀架選擇與介紹 ......................................50第 3 章 主軸脈沖發(fā)生器介紹與選型 ...........................523.1 光電編碼器原理 ..........................................52普通車床的自動化改造33.2 主軸脈沖發(fā)生器的安裝 ....................................533.3 主軸脈沖發(fā)生器的選擇 ....................................53第 4 章 普通車床自動化改造的單片機控制 ....................564.1 系統(tǒng)設計 ................................................564.2 用單片機控制系統(tǒng)電路 ....................................584.2.1 存儲器擴張電路 ....................................584.2.2 面板操作鍵和功能選擇開關 ..........................614.2.3 功能選擇開關 ......................................624.2.4 鍵盤、顯示器接口電路 ..............................634.2.5 步進電動機驅動電路設計 ............................644.2.6 M.S.T 接口 .......................................674.2.7 輔助電路設計 ......................................67第 5 章 小結 ...........................................69參考文獻 ..............................................70英文原文 ..............................................71中 文 譯 文 .............................................76致 謝 ................................................81普通車床的自動化改造4
