摘要


本研究之目的在於提出新型六連桿式衝床系統之新概念,並探討其系統化分析設計方法。本研究所提出之系統由馬達、減速機、變轉速聯軸器、及連桿機構所組合而成,其優點為可依據不同之運動需求,產生所需輸出運動。馬達與減速機連接,再與變轉速聯軸器連接連桿機構,進而產生複雜的輸出運動。因為變轉速聯軸器可快速更換,所以可輕易調整輸出運動。首先,針對各種傳統機械式衝床的構造與運動特性加以探討,並提出新型六連桿式衝床系統之概念。接著,利用向量迴路法推導出新型六連桿式衝床系統之運動分析方程式。然後,以最佳化方法設計出變轉速聯軸器之運動尺寸。並且,進行實例設計及模擬。最後,實際製作雛型機進行測試,以驗證其設計之正確性。由模擬與實驗結果顯示,所提系統可依據不同加工需求產生所需之輸出運動。除此之外,使其具有容易製造、成本低、高精度、及容易調整等優點。

The purpose of this study is to propose a novel press system with a six-link mechanism and its systematic methodologies of design and analysis. The proposed new press system is composed by a motor, a constant speed coupling, a gear reducer, a variable speed coupling, and a link mechanism. The motor and reducer are connected by the constant speed coupling, and then drive the links mechanism through the variable speed coupling. Since the variable speed coupling can be easily replaced by a coupling with different dimensions, or changed with different assembly configurations. The velocity and acceleration of the output can be adjusted to meet various motion requirements. First, the system is presented and its advantages are discussed. Then, the kinematic analysis of the system is performed by using the vector loop approach. Moreover, kinematic dimensions of the variable coupling are synthesized by using optimization method. Furthermore, the proposed approach is illustrated by a design example, and then kinematic simulation is performed by ADAMS software. Finally, a prototype and an experimental setup are established, and them the experiment is conducted. The results show that proposed new system can generate the expected output motions according to various forming requirements. In addition, it has the advantages of easy manufacture, low cost, high precision, and easy adjustability.
