Abstract

In the large-diameter main mirror lifting mechanism provided by the present invention, the lifting screw (1) is fixedly connected to the upper part of the lifting cylinder (2), and the upper part of the transition cylinder (3) is connected to the lower part of the lifting cylinder (2). fixed connection, the lower part of the transition cylinder (3) is installed on the bottom transition plate (8), the radial positioning component (4) is installed on the outer circumference of the transition cylinder (3), and the diameter The positioning component (4) can move up and down along the transition cylinder (3), the bottom circular plate (7) is installed on the bottom transition plate (8), and the bottom circular plate (7) is wound around the The outer circumference of the transition cylinder (3) is set, and the bottom positioning assembly (6) is fixedly installed on the bottom of the bottom circular plate (7). The large-diameter primary mirror lifting mechanism provided by the present invention utilizes the central hole of the primary mirror and the The central edge of the bottom realizes the lifting process of the primary mirror, which has a compact structure and does not occupy the outer edge of the primary mirror, and is widely used.

Description

technical field [0001] The invention relates to the technical field of optical instruments, in particular to a lifting mechanism for a large-caliber primary mirror. Background technique [0002] In the technical fields of space detection and astronomical observation, in order to improve the resolution, it is necessary to increase the aperture of the photoelectric detection equipment, resulting in a sharp increase in the size and weight of the primary mirror, and the cost is very expensive. Due to the fragility and fragility of the material of the primary mirror, its lifting, installation, handling and other operations are accompanied by great risks. If in the above process, disturbances such as excessive local stress and vibration overload may lead to irreversible damage such as chipping, breaking, and fracture of the primary mirror, this will bring great delay and delay to the development and service life of the entire photoelectric detection equipment. A sharp increase in...
