摘要
为了实现电视的焦距连续变化,设计了一种连续变焦距电视的变倍补偿机构。提出了一种提高变倍、补偿机构运动精度的方法,实测两机构直线运动精度均为15″。通过靶场试验证明连续变焦距电视的变倍补偿机构的运动精度满足电视捕获、跟踪目标的精度要求,两直线滑轨平行度调整机构设计、加工简单,可以在其它直线运动机构中得到推广应用。
In order to realize the continuous zooming for the focal length of television,a compensate mechanism of magnification is designed.A method to improve the kinematic accuracy of the magnification and compensate mechanism is presented in this paper.The linear movement precision of both mechanisms is about 15 ″.This kinematic accuracy of two mechanisms is proved to satisfy the requirements of acquiring and tracking target through the range tests.Further-more,the design and machining of parallelism adjusting mechanism is simple for two straight line skate,which could be widely used in other straight line movement mechanisms.
