摘要:

現今市售之自動化柵門，一般因使用減速機馬達以正逆轉控制，柵門搖桿之作動，易產生定位誤差，使柵門搖桿無法準確定位。因此本文提出一運用泛用型減速機馬達為動力源，單向等速驅動雙曲柄機構並串聯曲柄搖桿機構為六連桿機構。以此求得柵門搖桿作動於兩死點相位時，具運動近似停止狀態之可適性運動性能曲線的方法，研製出一具高精度定位、迅速作動、低震動、易製作、低成本之自動化柵門定位機構。本研究並以實務製作方式，完成性能測試實驗，證實其具實用價值。

The use of the motor of speed reducer for forward and reverse control and the movement of the rocker arm by the commercially available automatic gates tend to lead to positioning errors, leaving the rocker arm unable to accurately position. In the study, using the motor of speedreducer as the main power source, a six bar linkage is created through the series connection of a unidirectional constant velocity double crankmechanism and a crank rocker mechanism. A performance curve indicating there is almost no motion when the rocker arm moves between two dead-center positions is thus obtained for the research and development of a positioning mechanism of high-precision, fast actuation speed, low vibration, easy to manufacture and low cost. The study develops a real working model, conducts performancetesting and confirms the practical benefits of the positioning mechanism.
