摘要: 隨著我國工業(yè)生產(chǎn)的發(fā)展,機(jī)械工業(yè)即將面臨著一個(gè)十分重要的課題----設(shè)備改造。本設(shè)計(jì)就是對(duì)CA6140車床的機(jī)械部分，進(jìn)行數(shù)控改造。數(shù)控改造主要是簡(jiǎn)化機(jī)械傳動(dòng)機(jī)構(gòu)、縮短傳動(dòng)鏈、提高自動(dòng)化程度，也是為了解決復(fù)雜的零件加工、精度控制及提高產(chǎn)品質(zhì)量和生產(chǎn)率。在設(shè)計(jì)內(nèi)容上，主要針對(duì)傳動(dòng)系統(tǒng)圖和進(jìn)給系統(tǒng)的改造設(shè)計(jì)、以及導(dǎo)軌和自動(dòng)轉(zhuǎn)位刀架的改造設(shè)計(jì)等。
目前,經(jīng)濟(jì)型數(shù)控機(jī)床,仍然是我國市場(chǎng)經(jīng)濟(jì)需要量最大、銷售量最高。在利用我國現(xiàn)有的大量閑置舊機(jī)床，對(duì)舊機(jī)床進(jìn)行數(shù)控化改造，研制出一種新型高效、多能的經(jīng)濟(jì)型數(shù)控機(jī)床，是一種推陳出新、盤活存量資金的有效方法和低成本自動(dòng)必由之路。

Summary: With the development of industrial production of our country, the mechanical industry will face a very important subject soon ----the equipment transformation. It means simplify mechanical drove, control precision, and improve the product quality and productivity by shortening drive chain, raising automatic degree. At designing content, mainly, control and improve the product quality and productivity for solving complicated part processing, precision too. At designing content, mainly focus on the transformation of the system design and the transformation of the location of the knife and guide.
At present, economy numerical control lathe is still the lather which is required most heavy and sold at the largest volume. Based on that utilize the large amount of unused old lathe, carry on the numerical control transformation to the old lathe , develop one new type high efficient , multi-functional economy numerical control lathe are the best and only way to low coat and stock of fund.
Key word: Original design, Numerical control reformation, Main shaft, Knife rest, Guide, Numerical control device, Enter to the system.
