V帶測(cè)長(zhǎng)磨削機(jī)單片機(jī)控制系統(tǒng)軟件設(shè)計(jì)





摘     要



V帶屬新型的傳動(dòng)帶，現(xiàn)已得到了越來(lái)越廣泛的應(yīng)用，尤其是近年來(lái)隨著我國(guó)人民生活水平日益提高，汽車V帶等產(chǎn)品的需求大幅度增加，帶動(dòng)我國(guó)橡膠行業(yè)中V帶生產(chǎn)規(guī)模迅速擴(kuò)大。V帶測(cè)長(zhǎng)磨削機(jī)是V帶生產(chǎn)過(guò)程的關(guān)鍵設(shè)備之一，對(duì)提高V帶的產(chǎn)品質(zhì)量和生產(chǎn)效率起至關(guān)重要的作用。



V帶尺寸的精確十分重要，一是因?yàn)閷?duì)傳動(dòng)性能有很大的影響，除要求V帶的截面尺寸必須具有一定的準(zhǔn)確性外，V帶的長(zhǎng)度也必須滿足一定的要求。二是因?yàn)橐蠂?guó)際標(biāo)準(zhǔn)和歐美標(biāo)準(zhǔn)。為使同時(shí)使用的一組V帶長(zhǎng)度一致，每條V帶的長(zhǎng)度必須控制在一個(gè)比較小的誤差范圍內(nèi)，常需要專用的測(cè)長(zhǎng)機(jī)測(cè)量后進(jìn)行配組。目前國(guó)內(nèi)生產(chǎn)V帶的廠家，除了一些采用進(jìn)口單鼓切割機(jī)的切割后不再需要打磨外，采用雙鼓切割機(jī)的大部分中小型企業(yè)都需要有打磨V帶這一最后工序。許多生產(chǎn)廠家的做法是：對(duì)長(zhǎng)度要求不高的產(chǎn)品，切割后的V帶在簡(jiǎn)易型的磨削機(jī)上進(jìn)行打磨而不再進(jìn)行測(cè)長(zhǎng)。隨著V帶使用廠家對(duì)V帶配組要求的提高，許多中小型廠原有的簡(jiǎn)易型打磨機(jī)由于不能保證V帶的長(zhǎng)度已顯落后，迫切需要在這類打磨機(jī)上安裝測(cè)長(zhǎng)打磨為一體的控制系統(tǒng)，以保證V帶尺寸的精度與產(chǎn)品質(zhì)量。



    本文第一章主要介紹了V帶的在國(guó)民生產(chǎn)和人們生活中的應(yīng)用，國(guó)內(nèi)外制造V帶的設(shè)備和所面臨的問(wèn)題，即研究背景。

    第三章主要介紹了V帶測(cè)長(zhǎng)磨削機(jī)控制系統(tǒng)的硬件組成，包含了主控板、電動(dòng)機(jī)、傳感器、觸摸屏以及控制面板等部分。



第四章主要介紹了V帶測(cè)長(zhǎng)磨削機(jī)單片機(jī)控制系統(tǒng)的軟件設(shè)計(jì)，包含了主程序、部分子程序、通信程序與觸摸屏程序的設(shè)計(jì)。主要的子程序有：初始化程序、回零程序、測(cè)量程序、定長(zhǎng)程序，正反磨程序和復(fù)位程序等。通信程序是單片機(jī)與觸摸屏間的通信程序。子程序的設(shè)計(jì)主要是程序的功能、流程及結(jié)構(gòu)設(shè)計(jì)，包括介葽@絳蠣⒐δ艿?。单片机与触摸苾捎空C絳虻納杓剖遣捎肦S232串口通信，通過(guò)設(shè)定協(xié)議實(shí)現(xiàn)兩者間的數(shù)據(jù)交換。

Design of measuring long V-belt grinding machine controled by single chip microcomputer system software





Abstract



V belt is the new transmission belt, already obtained more and more widespread application, particularly enhanced day by day in recent years along with our country living standards, product and so on automobile V belt demands increased large scale, lead in our country rubber profession V belt scale of production to expand rapidly. V belt measured that the long milling machine is one of V belt production process key equipments, to improves V belt's product quality and the production efficiency plays the very important role.



V belt size precise very important; first, because has the very tremendous influence to the transmission performance, besides requests V belt's section size to have certain accuracy, V belt's length must satisfy certain request. Second, because must conform to the international standard and the European and American standard. Simultaneously in order to cause a group of V belt length which uses to be consistent, each V belt's length must control in a quite small error range, after often needs the special-purpose metroscope survey, carries on matches the group. At present the home production V belt's factory, uses import gangu cutter's cutting after some no longer needs to polish, uses the double drum cutter's majority Small and medium-sized enterprise to need to have polishes V belt this finishing operation. Many Manufacturer's procedure is: To the length request not high product, after the cutting V belt carries on the polish on the simple milling machine no longer to carry on measures is long. Uses the factory along with V belt to match the enhancement which for V belt the group requests, because many middle and small scale factory original simple dressers cannot guarantee that V belt's length obviously fell behind, urgent needs to install on this kind of dresser measured that the long polish is a body's control system, guarantees V belt size the precision and the product quality.



The first chapter mainly introduced V belt, in the national dividend and the people live the application, domestic and foreign makes the question which V belt's equipment and faces, namely research background. Chapter 3 control system hardware which introduces and should whet to pare machine..
