C2-3003車床的數(shù)控化再制造研究(本科畢業(yè)論文設(shè)計(jì))

摘要
電能是現(xiàn)代最常用且極為普遍的一種二次能源。電能具有許多優(yōu)點(diǎn),表現(xiàn)在:它的生產(chǎn)、傳輸、控制和使用都比較方便,且效率高,因而廣泛用于工農(nóng)業(yè)生產(chǎn)、交通運(yùn)輸、科學(xué)技術(shù)、信息傳輸及日常生活中,極大地推動(dòng)了技術(shù)的進(jìn)步和生產(chǎn)力的發(fā)展。
電機(jī)是與電能的生產(chǎn)、傳輸和使用又有著密切關(guān)系的電磁機(jī)構(gòu)。例如:將自然界的一次能源如水能、熱能、風(fēng)能和原子能等轉(zhuǎn)換為電能需要發(fā)電機(jī),它是電廠的主要電氣設(shè)備;為了經(jīng)濟(jì)地使用和分配電能需用變壓器,它是電力系統(tǒng)的主要電氣設(shè)備;在其他各行各業(yè)各部門都大量使用各種電動(dòng)機(jī)作為原動(dòng)機(jī),用以拖動(dòng)各種機(jī)械設(shè)備,這稱為電力拖動(dòng);在軍事、信息和各種自動(dòng)控制系統(tǒng)中,則應(yīng)用大量的控制電機(jī),作為檢測(cè)、執(zhí)行和計(jì)算等元件;在醫(yī)療、文教和日常生活中,電機(jī)的應(yīng)用也十分廣泛。
隨著電機(jī)及電力拖動(dòng)技術(shù)的發(fā)展,其控制技術(shù)業(yè)發(fā)展迅速。特別是隨著數(shù)控、電力電子、計(jì)算機(jī)及網(wǎng)絡(luò)等技術(shù)的發(fā)展,電力拖動(dòng)也正向自動(dòng)控制系統(tǒng)------無觸點(diǎn)控制系統(tǒng)、計(jì)算機(jī)控制系統(tǒng)邁進(jìn)。
本次設(shè)計(jì)是機(jī)床電氣工程及自動(dòng)化、機(jī)電、應(yīng)用電子技術(shù)等專業(yè)的一次綜合設(shè)計(jì)。本次設(shè)計(jì)任務(wù)是培養(yǎng)學(xué)生掌握相關(guān)的基本理論,能借助計(jì)算機(jī)及相關(guān)軟件來進(jìn)行本次設(shè)計(jì),最后既有較高的專業(yè)技術(shù)應(yīng)用能力。

關(guān)鍵詞:(二次能源,計(jì)算機(jī)網(wǎng)絡(luò)技術(shù),電力拖動(dòng),控制技術(shù))

 

 

ABSTRACT

Energy is the most commonly used and common secondary energy in modern society.It has many advantages,performancing in the production,transmission,control and use are relatively easy,particular in its high efficiency.So,widely uesd in industrial and agricultural production,transportation,science and technology,information transmission and daily life.Great impetus to technological progress and the development of productive forces.
Electric power is an electromagnetic bodier which is closed with the production,transmission and use.For example:the nature of this energy such as water energy,geothermal energy,wind and nuclerr energy into electric energy needs generators,It’s the main electrical power plant equipment.In order to economic use and distribution of electric need transformer,It is the main electrical power system equipment.Other businesses and departments all large-scale use the motor as the original motivation.To drag all kinds of mechanical equipment,this is known as the electric drive;In the military,information and automated systems,the application of a large number of motor control,as a test,implementation and computing components;In health care,culture,education life,the motor is also very broad application.
With the electrical and electric drive technology development,their control technology industry has developed rapidly.Special in the wake of NC,power electronics,computer and network technology development,power forward also drag the automatic control system——non-contact control systems,computer control system.
This design is automated machine tools and electrical engineering,mechanical and electrical,electronic technology,and other professional applications of a comprehensive design.The design task is to train students to master the basic theories,use of computer and related software for this design,both the higher end of the porfessional and technical capabilities.

Key words:(Secondary energy ,computer network technology,electric drive,control technology)
