1、畢業(yè)論文（設(shè)計）X-Y數(shù)控工作臺機電系統(tǒng)設(shè)計學生姓名學號專業(yè)械設(shè)計制造及其自動化班級指導(dǎo)教師學部機電工程學部答辯日期黑龍江東方學院學士學位畢業(yè)論文IX-Y數(shù)控工作臺機電系統(tǒng)設(shè)計摘要X-Y數(shù)控工作臺機電系統(tǒng)設(shè)計是一個開環(huán)控制系統(tǒng),其結(jié)構(gòu)簡單。實現(xiàn)方便而且能夠保證一定的精度。降低成本,是微機控制技術(shù)的最簡單的應(yīng)用。它充分的利用了危機的軟件硬件功能以實現(xiàn)對機床的控制；使機床的加工范圍擴大,精度和可靠性進一步得到提高。X-Y數(shù)控工作臺機電系統(tǒng)設(shè)計是利用8031單片機,及2764,6264存儲器及8155芯片等硬件組成,在控制系統(tǒng)的硬件上編寫一定的程序以實現(xiàn)一定的加工功能。其基本思想是:通過圓弧或者直線
2、插補程序以實現(xiàn)對零件進行幾何加工,每進行一段加工都要產(chǎn)生一定的脈沖以驅(qū)動電機正反轉(zhuǎn),同時通過8155(1)將相應(yīng)的加工進刀信息送至刀架庫中以實現(xiàn)以之相應(yīng)的走刀,電機和刀具的相對運動所以實現(xiàn)了刀具對工件的加工。該控制系統(tǒng)采用軟件中斷控制系統(tǒng)結(jié)構(gòu)及子程序結(jié)構(gòu)簡單，條件明確在經(jīng)濟型數(shù)控中應(yīng)用較多。中斷結(jié)構(gòu)采用模塊化結(jié)構(gòu)設(shè)計因為這種結(jié)構(gòu)便于修改和擴充，編制較為方便，便于向多處理方向發(fā)展。X-Y數(shù)控工作臺機電系統(tǒng)設(shè)計采用步進電機作為驅(qū)動裝置。步進電機是一個將脈沖信號轉(zhuǎn)移成角位移的機電式數(shù)模轉(zhuǎn)換器裝置。其工作原理是：每給一個脈沖便在定子電路中產(chǎn)生一定的空間旋轉(zhuǎn)磁場；由于步進電機通的是三相交流電所以輸入的脈
3、沖數(shù)目及時間間隔不同，轉(zhuǎn)子的旋轉(zhuǎn)快慢及旋轉(zhuǎn)時間的長短也是不同的。由于旋轉(zhuǎn)磁場對放入其中的通電導(dǎo)體既轉(zhuǎn)子切割磁力線時具有力的作用，從實現(xiàn)了旋轉(zhuǎn)磁場的轉(zhuǎn)動迫使轉(zhuǎn)子作相應(yīng)的轉(zhuǎn)動，所以轉(zhuǎn)子才可以實現(xiàn)轉(zhuǎn)子帶動絲杠作相應(yīng)的運動。本題目是步進電機，微型計算機，插補原理，匯編語言的綜合應(yīng)用，本題目設(shè)計得到了老師的幫助和支持，最后由董玉紅老師審定，在此表示感謝。本題目由方世龍完成，共分六章，第一章主要設(shè)計總體方案設(shè)計第二章主要設(shè)計了機械系統(tǒng)設(shè)計；第三章主要設(shè)計了控制系統(tǒng)硬件設(shè)計；第四章主要設(shè)計控制系統(tǒng)軟件設(shè)計；第五章主要是本設(shè)計的附錄。因本人水平有限，錯誤和不足之處在所難免，處理問題也有不妥之處，敬請相關(guān)老師批
