凸輪機構廣泛應用於製藥機械、食品包裝機械、壓力機自動送料機、玻璃機械、陶瓷機械、煙草機械、灌裝機械、印刷機械、電子機械及加工中心自動換刀裝置等,但是凸輪機構會有誤差容忍度低、凸輪與從動件發生分離現象、回動彈簧降低共振頻率、生產成本高昂等等缺點。
因此本文將以平面滑塊六連桿機構合成具有暫停運動之凸輪機構,使用解答平面法的概念搭配連桿機構分析、曲率半徑分析與限制條件,撰寫出一個滑塊六連桿機構合成程式來輔助設計連桿尺寸,以達到與凸輪與從動件之運動曲線相似的連桿機構。
最後以包裝機中的熱封裝置凸輪曲線當作實例,使用該程式成功合成出一組近似於熱封裝置凸輪曲線的連桿尺寸,證實此種機構與解答平面法之電腦輔助合成能有效幫助使用者合成具凸輪與從動件之運動曲線的連桿機構。
Recently, cam mechanism is widely used in pharmaceutical machinery, food packaging machinery, presses automatic feeding machine, glass machinery, ceramic machinery, tobacco machinery, filling machinery, printing machinery, electronic machinery and machining center automatic tool changer. However, the cam mechanism will have low allowance of tolerance, separating from follower, the spring reducing the resonant frequency, high production costs and so shortcomings.
In this thesis, a slider six-bar mechanism was designed to replace dwell cam mechanism. Use the concept of solution plane method with bar linkage analysis, curvature radius analysis and limiting conditions. Then, write a program of slider six-bar mechanism synthesis to assist the design of the linkage size to achieve similar to the follower movement curve.
In the end of this article, there is an example of using this program to successfully synthesize a set of linkages that approximate the cam curve of the heat seal device. It is confirmed that the computer-aided synthesis of the mechanism and the solution plane method can help the user to synthesize the linkage mechanism with the motion curve of the dwell cam mechanism.
