課題來源
本論文課題是由社會實際生產(chǎn)應用中提出
科學依據(jù)(包括課題的科學意義;國內(nèi)外研究概況、水平和發(fā)展趨勢;應用前景等)
(1)課題科學意義
中國是一個有上下五千年歷史的文明古國,從原始的石器時代到金屬時代,我們偉大的祖先就進行了簡單的機械加工,但是在當時的生產(chǎn)條件下,其生產(chǎn)效率都是非常低下的,隨著時代的發(fā)展,人們在想方設法改善自己的生存條件和生活水平,正是由于這點,促進了機械方面的飛速發(fā)展,人們正朝著一個效率更高,成本更低,更加方便化的方向發(fā)展。隨著社會、經(jīng)濟的快速發(fā)展,企業(yè)要在當前市場需求多變、競爭激烈的環(huán)境中生存和發(fā)展就需要迅速地更新企業(yè)生產(chǎn)設備與技術條件以高效、快速的進行生產(chǎn)加工以獲得最高生產(chǎn)率。其中橡膠制品的需求和應用越來越廣泛,比如汽車工業(yè)中的輪胎。因此橡膠切割機的開發(fā)和改進漸漸被國家和許多企業(yè)提上日程。而我國由于在這方面起點比較低,在國際社會處于比較落后的位置,以前橡膠切割機大多需要從國外進口。隨著近幾年來需求越來越大,我們急需改變這種狀況??上驳氖?,現(xiàn)在我國切割機生產(chǎn)廠家也漸漸多了起來,相信在不久的將來,我們就會實現(xiàn)在橡膠切割行業(yè)完全依靠自己的目標。本課題就是從這里出發(fā),根據(jù)已經(jīng)有的資料,對橡膠切割機進行改進,達到更方便可用的目的。橡膠切割機是一種常用的機械裝置,它體積小,重量輕,簡單而使用廣泛,能方便的移動使用。以前大都依靠日本進口。隨著國內(nèi)經(jīng)濟的飛速發(fā)展,橡膠切割機的事業(yè)日益增大。更需要一種替代產(chǎn)品。
(2)切割行業(yè)現(xiàn)狀及發(fā)展前景
我國切割行業(yè)主要有以下幾類生產(chǎn)企業(yè)組成1、門式切割機;2、小車式切割機及割嘴;3、等離子切割電源及割嘴;4、手工焊割炬及焊割嘴等。切割行業(yè)經(jīng)過幾十年的發(fā)展,其產(chǎn)品從單一的手工割炬發(fā)展成為一個門類較為齊全的產(chǎn)業(yè)。近年來,我國門式數(shù)控切割機生產(chǎn)技術的發(fā)展尤為迅速。
切割行業(yè)的發(fā)展始終與金屬制造企業(yè)(特別是造船業(yè))發(fā)展是分不開的,通過與這些企業(yè)的緊密合作和技術交流,給我們切割行業(yè),帶來了許多不同的生產(chǎn)理念和富有挑戰(zhàn)性的經(jīng)驗和技術?,F(xiàn)代金屬制造企業(yè)為了優(yōu)化其產(chǎn)品的結(jié)構性能,使得產(chǎn)品更經(jīng)濟,生產(chǎn)周期更短,在國際市場上更具競爭力。這就必須對其原有的制造技術和生產(chǎn)工藝提出新的設想和要求,部分設想和要求將要在切割設備上得以實現(xiàn)。這樣就對我們切割行業(yè)提出了新的課題和新的設計理念

機電一體化技術
機電一體化是一種混合技術,是機械技術與微電子技術、信息技術互相結(jié)合的產(chǎn)物,是機電工業(yè)發(fā)展的必然趨勢。
現(xiàn)代科學技術的發(fā)展大大地推動了不同學科的交流,引起了工程領域的技術改造與革命。在機械工程領域,由于微電子技術和計算機技術的迅速發(fā)展及其向機械工業(yè)的滲透所形成的機電一體化,使機械工業(yè)的技術結(jié)構、產(chǎn)品機構、功能與構成、生產(chǎn)方式及管理體系發(fā)生了巨大變化,使工業(yè)生產(chǎn)由“機械電氣化”邁入了“機電 一體化”為特征的發(fā)展階段。
一、機電一體化的核心技術
機電一體化包括軟件和硬件兩方面技術。硬件是由機械本體、傳感器、信息處理單元和驅(qū)動單元等部分組成。因此,為加速推進機電一體化的發(fā)展,必須從以下幾方面著手。
⑴ 機械本體技術
機械本體必須從改善性能、減輕質(zhì)量和提高精度等幾方面考慮。現(xiàn)代機械產(chǎn)品一般都是以鋼鐵材料為主,為了減輕質(zhì)量除了在結(jié)構上加以改進,還應考慮利用非金屬復合材料。只有機械本體減輕了重量,才有可能實現(xiàn)驅(qū)動系統(tǒng)的小型化,進而在控制方面改善快速響應特性,減少能量消耗,提高效率。
⑵ 傳感技術
傳感器的問題集中在提高可靠性、靈敏度和精確度方面,提高可靠性與防干擾有著直接的關系。為了避免電干擾,目前有采用光纖電纜傳感器的趨勢。對外部信息傳感器來說,目前主要發(fā)展非接觸型檢測技術。
⑶ 信息處理技術
機電一體化與微電子學的顯著進步、信息處理設備(特別是微型計算機)的普及應用緊密相連。為進一步發(fā)展機電一體化,必須提高信息處理設備的可靠性,包括模/數(shù)轉(zhuǎn)換設備的可靠性和分時處理的輸入輸?shù)目煽啃?進而提高處理速度,并解決抗干擾及標準化問題。
⑷ 驅(qū)動技術
電機作為驅(qū)動機構已被廣泛采用,但在快速響應和效率等方面還存在一些問題。目前,正在積極發(fā)展內(nèi)部裝有編碼器的電機以及控制專用組件-傳感器-電機三位一體的伺服驅(qū)動單元。
⑸ 接口技術
為了與計算機進行通信,必須使數(shù)據(jù)傳遞的格式標準化、規(guī)格化。接口采用同一標準規(guī)格不僅有利于信息傳遞和維修, 而且可以簡化設計。目前,技術人員正致力于開發(fā)低成本、高速串行的接口,來解決信號電纜非接觸化、光導纖維以及光藕器的大容量化、小型化、標準化等問題。
⑹ 軟件技術
軟件與硬件必須協(xié)調(diào)一致地發(fā)展。為了減少軟件的研制成本,提高生產(chǎn)維修的效率,要逐步推行軟件標準化,包括程序標準化、程序模塊化、軟件程序的固化、推行軟件工程等。
二、機電一體化技術的主要應用領域
⑴數(shù)控機床
數(shù)控機床及相應的數(shù)控技術經(jīng)過40年的發(fā)展,在結(jié)構、功能、操作和控制精度上都有迅速提高,具體表現(xiàn)在:
1、總線式、模塊化、緊湊型的結(jié)構,即采用多C PU、多主總線的體系結(jié)構。
2、開放性設計,即硬件體系結(jié)構和功能模塊具有層次性、兼容性、符合接口標準,能最大限度地提高用戶的使用效益。
3、W O P技術和智能化。系統(tǒng)能提供面向車間的編程技術和實現(xiàn)二、三維加工過程的動態(tài)仿真,并引入在線診斷、模糊控制等智能機制。
4、大容量存儲器的應用和軟件的模塊化設計,不僅豐富了數(shù)控功能,同時也加強了C N C系統(tǒng)的控制功能。
5、能實現(xiàn)多過程、多通道控制,即具有一臺機床同時完成多個獨立加工任務或控制多臺和多種機床的能力,并將刀具破損檢測、物料搬運、機械手等控制都集成到系統(tǒng)中去。
6、系統(tǒng)的多級網(wǎng)絡功能,加強了系統(tǒng)組合及構成復雜加工系統(tǒng)的能力。
7、以單板、單片機作為控制機,加上專用芯片及模板組成結(jié)構緊湊的數(shù)控裝置。
⑵計算機集成制造系統(tǒng)(CIMS)
CIMS的實現(xiàn)不是現(xiàn)有各分散系統(tǒng)的簡單組合,而是全局動態(tài)最優(yōu)綜合。它打破原有部門之間的界線,以制造為基干來控制“物流”和“信息流”,實現(xiàn)從經(jīng)營決策、產(chǎn)品開發(fā)、生產(chǎn)準備、生產(chǎn)實驗到生產(chǎn)經(jīng)營管理的有機結(jié)合。企業(yè)集成度的提高可以使各種生產(chǎn)要素之間的配置得到更好的優(yōu)化,各種生產(chǎn)要素的潛力
可以得到更大的發(fā)揮。
⑶柔性制造系統(tǒng)(FMS)
柔性制造系統(tǒng)是計算機化的制造系統(tǒng),主要由計算機、數(shù)控機床、機器人、料盤、自動搬運小車和自動化倉庫等組成。它可以隨機地、實時地、按量地按照裝配部門的要求,生產(chǎn)其能力范圍內(nèi)的任何工件,特別適于多品種、中小批量、設計更改頻繁的離散零件的批量生產(chǎn)。
⑷工業(yè)機器人
第1代機器人亦稱示教再現(xiàn)機器人,它們只能根據(jù)示教進行重復運動,對工作環(huán)境和作業(yè)對象的變化缺乏適應性和靈活性;第2代機器人帶有各種先進的傳感元件,能獲取作業(yè)環(huán)境和操作對象的簡單信息,通過計算機處理、分析,做出一定的判斷,對動作進行反
