Embodiment 1

[0031] Embodiment 1, with reference to Figure 1 ~ Figure 4 : The large gear 3 and the circular guide rail 4 are fixedly connected by screws and installed on the base 2. 6 matching slide blocks 5 are distributed on the circular guide rail 4 (see figure 2 ). Left single-rod joint bearing 9 (6 in total, see figure 2 ) are respectively connected to the corresponding sliders. Right single-rod joint bearing 7 (6 pieces in total, see figure 2 ) are connected to the focus panel 8 respectively. The left single rod joint bearing 9 is connected with the right single rod joint bearing 7 through the support rod 6 . The pinion 10 (total 6 that matches with bull gear 3, see figure 2 ) is connected to the slider 5 through the connecting plate. Drive motor 1 (total 6, see figure 2 ). When the drive motor 1 drives the pinion 10 to rotate, since the pinion 10 is connected to the slider 5, the pinion 10 drives the slider 5 to rotate around the big gear 3 together (the big gear 3 and ...

Abstract

An LAMOST astronomical telescope focal panel movement realizing mechanism is characterized in that a rotary movement mechanism, a tilted movement mechanism and a focusing movement mechanism are set as a co-movement mechanism, wherein, a large gear and a circular guide rail are fixedly connected on a base; six matched slide blocks are distributed on the circular guide rail; the slide blocks are connected with pinions through connecting plates; each pinion is meshed with the large gear; a drive motor is arranged on a shaft; the slide blocks are respectively connected with supporting rods through left single rod joint bearings; each supporting rod is connected on a focal panel through a right single rod joint bearing; every two supporting rods are arranged as one group in a V-shaped form, and one end of each of the two supporting rods leans against the connecting points of the focal panel through the right single rod joint bearings; three groups of connecting points are distributed in the same circle on the focal panel by 120 degrees; and the other end of each of the two supporting rods has a certain distance through the locations of the two slide blocks connected with the left single rod joint bearing on the circular guide rail. The invention not only simplifies the mechanical structure and the control system, but also improves the stability of the system.

Description

technical field [0001] The invention relates to a mechanism for realizing the movement of the focus panel of a LAMOST type astronomical telescope. By adopting this structure, the support of the focal plate of the LAMOST astronomical telescope is simplified. More importantly, it enables the focus panel to rotate around the vertex of its own spherical crown when changing the observation sky area, avoiding complex and cumbersome formula derivation and system calibration. Background technique [0002] The Large Sky Area Multi-Object Optical Fiber Spectroscopic Telescope, referred to as LAMOST, is a new type of Schmidt astronomical telescope proposed by Chinese astronomers and astronomical instrument experts at the end of the 20th century. It divides the primary mirror, secondary mirror and focal plate of the traditional Schmidt telescope into three independent parts, and the primary mirror is fixed during the telescope tracking process, and the Schmidt correction plate takes on...
