| Abstract | 用于天文望远镜副镜位置控制的高精度五维调机构，其特征在于，自下而上地设有：底板I、？底板II、底板III；其中底板I与望远镜机架相连，所述底板I与底板II之间，由一组X向弹性片固定联接，并设有X向直线电机；所述底板II与底板III之间，由一组Y向弹性片固定联接，并设有Y向直线电机；所述底板III的上面通过位移促动器I、位移促动器II与位移促动器III设置有镜面安装板；望远镜的副镜安装在该镜面安装板上。本发明结构简单，镜面在各自由度方向上的调节过程中不会出现间隙或空回现象。该天文望远镜副镜位置控制的高精度五维调节机构的位置调节精度在平动方向优于2微米，转动定位精度优于2角秒。 |
| Other Abstract | The invention discloses a high-precision five-dimension adjusting mechanism used for an astronomical telescope secondary mirror. The high-precision five-dimension adjusting mechanism is, from bottom to top, sequentially provided with a bottom plate I, a bottom plate II, and a bottom plate III. The high-precision five-dimension adjusting mechanism is characterized in that the bottom plate I is connected with a telescope rack, and the bottom plate I and the bottom plate II are fixedly connected together by a group of X-direction elastic sheets, and an X-direction linear motor is disposed between the bottom plate I and the bottom plate II; the bottom plate II and the bottom plate III are fixedly connected together by a group of Y-direction elastic sheets, and a Y-direction linear motor is disposed between bottom plate II and the bottom plate III; the upper surface of the bottom plate III is provided with a mirror surface installation plate by a displacement actuator I, a displacement actuator II, and a displacement actuator III; and the secondary mirror of the telescope is disposed on the mirror surface installation plate. According to the invention, the structure is simple, and the gap or backlash phenomenon cannot occur during the adjusting process of the mirror surface in directions of various freedom degrees. By adopting the high-precision five-dimension adjusting mechanism used for the astronomical telescope secondary mirror, the position adjusting precision is better than 2 micrometers in the translational direction, and the rotation positioning precision is better than 2 seconds of arc. |
