Nc machine tool is the collection puter technology, electronic technology, automatic control, sensing measurement, machinery manufacturing, and work munication technology in one of the typical electromechanical integration products. Its development and utilization, opened a new era of manufacturing, change the manufacturing production mode, industrial structure, management mode, make the pattern of world manufacturing industry, great changes have taken place. The level of NC technology has bee the core measure of a country39。但是我國是發(fā)展中國家，許多企業(yè)財力薄弱，不可能花費大量的資金添置許多全新的數(shù)控機床，同時大量的通用機床不可能全部淘汰。 我國是機床生產(chǎn)大國，又是使用大國。由于這類系統(tǒng)結(jié)構(gòu)簡單，價格便宜，非常適合中小型企業(yè)，目前仍是我國應(yīng)用面最廣的數(shù)控系統(tǒng)。如北京機床研究所的 BS9l 系統(tǒng)，這些系統(tǒng)一般配有 CRT 顯示器，可配置直流和交流伺服驅(qū)動， 2~4 軸聯(lián)動。如華中 I 型等數(shù)控系統(tǒng)，都具有多軸聯(lián) 動功能，快速進給速度在 ，具有較強的通信、管理功能。這種機床改造花費少，改造針對性強，時間短，改造后的機床大多能克服原機床缺點和存在的問題，生產(chǎn)效率高，尤其適合中國機床擁有量大、生產(chǎn)規(guī)模小的具體國情。為了滿足用戶的需求，減少成本及各種浪費，我們不能一味的大量添置全新的數(shù)控機床，而是考慮把普通機床改造為數(shù)控機床。它的發(fā)展和運用，開創(chuàng)了制造業(yè)的新時代，改變了制造業(yè)的生產(chǎn)方式、產(chǎn)業(yè)結(jié)構(gòu)、管理方式、使世界制造業(yè)的格局發(fā)生了巨大的變化。 1 提供全套畢業(yè)論文圖紙，歡迎咨詢 畢業(yè)設(shè)計 （論文） 題目： X502 型立式銑床微機數(shù)控改裝 （橫向） 學 院： 機械工程學院 專 業(yè)： 機電一體化工程 班 級： 機電 1202 學 號： 010113304504 姓 名： 李開帆 指導教師： 黃江 2020 年 10 月 31 日 I 摘要 數(shù)控機床具有高精度、高效、高速、高可靠性等優(yōu)點，并且機床結(jié)構(gòu)趨于模塊化、數(shù)控功能專門化。數(shù)控機床是集計算機技術(shù)、電子技術(shù)、自動控制、傳感測量、機械制 造、網(wǎng)絡(luò)通信技術(shù)于一體的典型的機電一體化產(chǎn)品。 數(shù)控技術(shù)水平的高低已經(jīng)成為衡量一個國家制造業(yè)現(xiàn)代化程度的核心標志，實現(xiàn)加工機床及生產(chǎn)過程數(shù)控化，己成為當今制造業(yè)的發(fā)展方向。普通機數(shù)控化改造，顧名思義就是在機床上增加微機控制裝置即單片機數(shù)控系統(tǒng)，使其伺服電機型機床具有一定的自 動化能力，使其傳動系統(tǒng)更加符合要求，以實現(xiàn)預定的加工工藝目標。 我國數(shù)控系統(tǒng)發(fā)展具有以下 3個特征： (l)高檔數(shù)控系統(tǒng)技術(shù)已經(jīng)突破。 (2)普及型數(shù)控系統(tǒng)技術(shù)已經(jīng)成熟。 (3)經(jīng)濟型數(shù)控系統(tǒng)仍有廣闊的市場前景。比較典型的有南京大方的 JWK 系列。數(shù)控機床是機械工業(yè)發(fā)展的關(guān)鍵產(chǎn)品，我國的數(shù)控機床在機床產(chǎn)品中的比例總體水平低。因此，把普通機床改造為數(shù)控機床則不失為是一條提高數(shù)控化率的有效途 徑，機床改造花費少，改造針對性強，時間短，改造 后的機床大多能克服原機床的缺點和存在的問題，生產(chǎn)效率高。s manufacturing industry modernization degree symbol, the processing machine and the production process of NC, has bee the development direction of manufacturing industry. In order to meet the needs of users, reduce cost and waste, we cannot blindly large additions of new CNC machine tools, but consider the general machine tools for the transformation of CNC machine tools. Ordinary machine CNC transformation, just as its name implies is in bed to increase the microputer control device is the singlechip digital control system, the servo motor type machine tool has some automation capabilities, the transmission system is more in line with the requirements, in order to achieve the goal of predetermined processing technology. This machine costs less, reform targeted, time is short, most of the machine after the original machine can overe the shortings and problems, high production efficiency, especially for the Chinese machine tool has a large amount ofspecific national conditions, the small scale of production. Our country numerical control system development has the following three characteristics: (l) have breakthrough highgrade CNC system. Such as huazhong type I numerical control system, all have the multiaxis linkage function, fast feed rate in more than m/s, with strong munication and management capabilities. (2) affordable numerical control system technology is mature. Such as Beijing machine tool research institute BS9l system, these systems are generally equipped with a CRT display, configurable dc and ac clothing drive, 2 ~ 4 axis III linkage. (3) the economical CNC system still has a broad market prospect. Because this kind of system structure is simple, cheap, very suitable for small and mediumsized enterprise, at present is still the most widely used nc system in our country. Typically have nanjing generous JWK series. China is big country of production of machine tools, it is with great power. NC machine tools is the key product development of mechanical industry, the proportion of the overall level of NC machine tool in our country machine tool products in the low. But China is a developing country, many enterprises financial weakness, can not spend a lot of money to acquire many new NC machine tools, and general machine tool large can not pletely eliminate. Therefore, the general machine tools to CNC machine tools is a effective way to improve the rate of NC machine tool rebuilding, spend less, reform targeted, time is short, after the transformation of the machine tool are able to overe the shortings and problems of the machine tool, the production efficiency is high.
