摘要:凸輪機構(gòu)作為機械傳動中重要的傳動方式，被廣泛地應(yīng)用于自動機械和自動控制裝置中。根據(jù)凸輪輪廓曲線可以得到各種預(yù)期的運動規(guī)律。凸輪機構(gòu)為高副機構(gòu)，由凸輪、推桿和機架3個構(gòu)件組成。凸輪機構(gòu)對凸輪輪廓曲線要求較高，必須保證輪廓曲線光滑以減少沖擊。傳統(tǒng)的凸輪設(shè)計為作圖法和解析法，作圖法得到的輪廓曲線較粗糙，作圖過程繁瑣，適用于對凸輪機構(gòu)要求不高的場合。解析法可以提高凸輪輪廓曲線的設(shè)計精度，但手工計算的數(shù)據(jù)點少，如果凸輪要求很高，就必須增加計算的點數(shù)，從而增加了工作量，而且得到的原始數(shù)據(jù)容易產(chǎn)生“拐點”。 隨著計算機輔助設(shè)計／計算機輔助制造(CAD／CAM)技術(shù)的益普及，新材料與熱處理新工藝的發(fā)展，凸輪的設(shè)計與制造已變得十分方便而精確，凸輪的使用壽命大幅度延長，制造成本不斷下降?？梢灶A(yù)計，凸輪機構(gòu)在自動機械中的應(yīng)用范圍，將越來越廣泛，其工作性能將獲得明顯的改善，從而將更好地促進自動機械的發(fā)展。利用計算機輔助設(shè)計可以大大提高工作效率，而且能夠快捷地得到精確的凸輪輪廓線。 本文介紹了如何運用Matlab語言繪制凸輪機構(gòu)的輪廓曲線，以及利用Guide工具編制一個操作界面。根據(jù)矢量法建立凸輪機構(gòu)的運動學(xué)方程。采用Matlab語言對其進行編程，得到凸輪機構(gòu)的輪廓曲線。該方法求解效率高，得到凸輪機構(gòu)的輪廓曲線較作圖法精確．避免了手工求解的麻煩，具有極高的實用價值。 關(guān)鍵詞：凸輪；Matlab；M文件；輪廓線；Guide
Abstract:CAM as mechanical transmission in important driving mode, is widely used in automatic machines and automatic control devices. According to the CAM contour curve can get the movement rule of various expected. CAM is high, the CAM, vice institutions push rod and frame three components. CAM to the demand is higher, CAM contour curve must ensure smooth contour curves in order to reduce the impact. The traditional CAM design for graphic method and analytic method, graphic method get outline curve is coarser, drawing process trivial, suitable for CAM mechanism of occasions with low requirements. Analytical method can improve the design of CAM contour curve manual calculation accuracy, but the data points less, if CAM is demanding, must increase calculation points, thus increasing the workload, and get to produce the original data "inflection point". Along with the computer aided design/computer aided manufacturing (CAD/CAM) technology, the new material and PE popularize new process development, heat CAM design and manufacturing has become very convenient and accurate, greatly extend the service life of CAM, manufacturing costs continue to drop. Can be expected in the automatic machinery, CAM application scope, will more and more extensive, its performance will obtain obvious improvement, which will facilitate the development of automatic machinery. Using a computer aided design can greatly improve work efficiency, but also can quickly obtain precise CAM contour line. This paper introduces how to use Matlab language outline curve drawing CAM mechanism. Based on vector method to establish the CAM mechanism kinematic equation. Based on Matlab language of its programming, get CAM outline curve. This method is of high efficiency, get CAM outline curve more graphic method precise. Avoid the trouble, the manual solution has high practical value. Keywords: CAM; Matlab; M files; Contour line; Guide
