Abstract

The invention discloses a welding fixing structure suitable for an adjustable reflector group. The fixing structure comprises a reflector group and a reflector bracket (4), the reflector group is coaxially arranged in the reflector bracket (4), a gap is reserved between the reflector group and the reflector bracket (4), the gap is filled with soldering paste, and the reflector group and the reflector bracket (4) are welded and fixedly connected through the soldering paste. According to the invention, the adopted welding fixing mode allows no initial connection between the reflector group and the reflector bracket, so that the reflector group can realize five-dimensional free adjustment in the space by using the adjustment tool, and the overall efficiency of adjustment of the reflector group is further improved; and the common welding process in the electronic assembly industry is creatively improved and is applied to the fixed connection of the light machine assembly, so that the low-stress fixed connection is realized, and meanwhile, the good rigidity of the assembly is ensured.

Description

technical field [0001] The invention belongs to the technical field of precision assembly and adjustment of high imaging quality optical systems, and relates to a welding fixing structure and a fixing method suitable for an adjustable mirror group. Background technique [0002] The Cassegrain optical system is composed of an aspheric primary mirror and a secondary mirror. The position accuracy of the secondary mirror relative to the primary mirror directly determines the imaging quality and optical performance of the system. Therefore, the key point of the system’s installation and adjustment is to use interferometric The method measures the wave aberration information of the system in real time, and precisely adjusts the spatial orientation of the secondary mirror to ensure that the system performance meets the design expectations. The common optical-mechanical structure of the cassette system is: the secondary mirror assembly (secondary mirror + secondary frame) is positio...
