The invention discloses an angle-adaptive high-precision mirror-body lateral support mechanism and belongs to the technical field of ground precision optical experiments with an aim to solve problems that application range is relatively singular, surface figure precision of an entire mirror body cannot guaranteed, the entire mirror body is heavy and complicated in structure. The angle-adaptive high-precision mirror-body lateral support mechanism comprises an annular support plate, multiple bonding blocks circumferentially and evenly distributed on the lateral wall of the mirror body and multiple support mechanisms circumferentially distributed; the bonding blocks are adhesively fixed with the lateral wall of the mirror body; each lateral support mechanism comprises a connecting rod,, a lever structure, a lever base, a lever center shaft, a lateral support base and a counterweight structure; one end of the connecting rod is connected to one end of the lever structure while the other end of the connecting rod is adhesively fixed with one bonding block, the other end of the lever structure is connected with the counterweight structure, the lever center shaft penetrates the lever structure, two ends of the lever center shaft are connected with the lever base, the lateral wall of the lever base is fixed on the lateral wall of the lateral support base through fixing bolts, and the lateral support base is arranged on the upper end face of the support plate.
Description
technical field [0001] The invention belongs to the technical field of precision optical experiments on the ground, and in particular relates to an angle-adaptive high-precision mirror body lateral support mechanism. Background technique [0002] In the process of testing, testing, assembling and using the large mirror body on the ground, due to the limitation of testing equipment, experimental environment and use status, the traditional large mirror body generally adopts back support to ensure that the whole mirror body is in use. The surface shape accuracy in the process and the design plan adopt the method of vertical optical axis, which greatly limits the scope of application of the mirror body. Therefore, it is necessary to design a reasonable side support structure for the yaw or pitch of the mirror body to reduce the surface shape change of the entire mirror body and ensure the imaging quality of the large mirror body. [0003] At present, large-scale mirrors on the ...
