The invention discloses a high-precision, high-stability and compact telescope three-mirror pitching adjustment mechanism, relates to the technical field of large-aperture telescope installation and adjustment, and solves the problems of use and installation and adjustment of a three-mirror system of a foundation large-aperture photoelectric telescope. According to the invention, the crisscross metal diaphragms are used as the rotating hinges, so no gap exists in rotation within a small angle range, and high stability and high rigidity are achieved; compared with a scheme adopting a bearing, the three-mirror pitching adjustment mechanism is simple and stable in structure, and high-precision and lockable three-mirror pitching change adjustment convenient to install and adjust can be realized by matching with a ball head rod-V-shaped groove-disc spring fine adjustment and locking mechanism; meanwhile, the frame type splicing supporting frame which is compact in structure design is adopted, the structure is simple and stable, and the size is small. The mechanism designed by the invention is already put into manufacturing and use, and actual experimental tests and use effect evaluation prove that the three-mirror pitching adjusting mechanism is reliable, efficient and excellent in practical performance.
Description
technical field [0001] The invention relates to the technical field of large-aperture telescope assembly and adjustment, in particular to a high-precision, high-stability, and compact three-mirror pitch adjustment mechanism for a ground-based large-aperture telescope. Background technique [0002] In recent years, the aperture of the optical system of the high-resolution imaging ground-based photoelectric telescopes that has developed rapidly in recent years has become larger and larger, and the size of the primary mirror of the telescope has gradually developed from 1 meter to 2 meters, 4 meters and larger. At present, the large-aperture ground-based telescope with the most mature technology development and the most widely used in my country has a caliber ranging from 1 meter to 4 meters. In a typical optical system, the primary and secondary mirrors adopt a coaxial reflection type, converging the light near the primary mirror. On the plane three mirrors at the central hole,...
