【正文】 作估算，僅節(jié)約電力一項每年節(jié)約電能將近 161 億 KW/h，這該是多么可觀的一筆節(jié)能挖潛的經(jīng)濟效益呀！本課題是結(jié)合 PLC 和變頻技術(shù)對普通C6150 機床進行節(jié)能改造。因此除了要進行計算傳動比 1：3 的齒輪箱的機械設(shè)計，還要把這個多軸傳動折算到電動機軸側(cè)，以驗算改造后的 GD178。（4）變頻器程序譯碼器實現(xiàn)電子觸摸屏轉(zhuǎn)速設(shè)定 如（2）所述，變頻器接受 3 個信號譯出 8 種轉(zhuǎn)速作為變頻器給定；另外通過變頻器預(yù)先設(shè)置參數(shù)，存儲 8 種自動變速的車削方案曲線，通過組合鍵選擇，使變頻器按存儲的不同轉(zhuǎn)速切削過程自動調(diào)速。該同學(xué)收集的數(shù)據(jù)資料較翔實，分析和論證有一定深度，結(jié)論正確合理。是否同意安排論文答辯：同意論文成績：80 分評閱教師（簽名）： 年 月 日北京交通大學(xué)畢業(yè)設(shè)計（論文）答辯小組評議意見學(xué)號 專業(yè) 電氣工程及其自動化車床主軸多動變頻調(diào)速節(jié)能改造設(shè)計職 稱 工作單位 備注組長80 分畢業(yè)設(shè)計（論文）誠信聲明本人聲明所呈交的畢業(yè)設(shè)計（論文） ，是本人在指導(dǎo)教師的指導(dǎo)下，獨立進行研究工作所取得的成果，除了文中特別加以標(biāo)注和致謝中所羅列的內(nèi)容以外，畢業(yè)設(shè)計（論文）中不包含其他人已經(jīng)發(fā)表或撰寫過的研究成果，也不包含為獲得北京交通大學(xué)海濱學(xué)院或其他教育機構(gòu)的學(xué)位或證書而使用過的材料。主要研究完成了對普通車床的工作原理進行了分析研究，簡單介紹了普通車床的拖動系統(tǒng)及機械特性，然后重點介紹了普通車床的原拖動系統(tǒng)。關(guān)鍵詞：電機轉(zhuǎn)矩線；機械傳動比；變頻調(diào)速；PLC 編程；電子觸摸屏iiABSTRACTThe lathe has bee the most widely used industrial device processing an indispensable machine, but I lived lathe application level for the world is relatively low, over the years is through the handle to control the rotational speed of the spindle, the operation is very plicated, in this paper, ordinary lathe as the object of study, of the mon lathe is designed transformation of frequency control of motor speed. The main research work principle of ordinary lathe for analysis and research, introduced the drive system and mechanical properties of ordinary lathe, and then focuses on the primary drive system of lathe. With PLC control to achieve the purpose of variable frequency speed regulation. After frequency conversion transformation, the practical application effect of lathe is good, and also with the energy saving, easy control of the existing motor control, can be popularized in large area in the field of application of lathe.This thesis is a summary of mon lathe design project technology, mainly introduces the principle of frequency conversion, the working principle of PLC control principle, general machine tools, machine tool was realized by the stepless speed regulating motor, the original is changed to energysaving inverter design after the , through the electronic touch screen to achieve the speed switching function.KEYWORDS：Motor torque line。 electronic touch screeniii目 錄摘 要 ........................................................................................................................iABSTRACT..............................................................................................................ii目 錄 ......................................................................................................................iii1. 緒論 ......................................................................................................................12. 普通車床主軸的變頻調(diào)速 ..................................................................................2 普通車床的主要功能與構(gòu)造 ......................................................................2 普通車床的主要功能 ........................................................................2 普通車床的構(gòu)造 ................................................................................2 普通車床的拖動系統(tǒng) ..................................................................................3 普通車床的運動系統(tǒng) ........................................................................3 普通車床主拖動系統(tǒng)的機械特性 ....................................................3 主拖動系統(tǒng)的負載功率 ....................................................................4 主拖動系統(tǒng)的工作特點 ....................................................................4 普通車床的原拖動系統(tǒng) ....................................................................5 車床主拖動的變頻調(diào)速系統(tǒng) ......................................................................5 對變頻調(diào)速系統(tǒng)的基本考慮 ............................................................5 低速轉(zhuǎn)保留一級傳動比，且 方案 ......................................6????≤???? 低速轉(zhuǎn)保留一級傳動比，且 方案 ...................................7????????????3. 變頻調(diào)速的原理 ................................................................................................10 變頻器的控制方式 ....................................................................................10 變頻器的頻率給定 ....................................................................................104.
