Embodiment Construction
[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.
[0025] In order to avoid the influence of self-weight and tooling constraints on the surface shape during the processing of large-diameter mirrors, the present invention uses flexible support structures and stress state test sensors to monitor the stress state of large-diameter mirrors before and after coating. The change of the stress state is to adjust the preload of the flexible support structure on the large-aperture reflector, reduce the influence of the disassembly and assembly of the flexible support structure on the surface shape of the large-aperture reflector, and provide for ...

The invention discloses a processing and adjusting device and method for a large-aperture reflector. The device comprises a back flexible supporting structure, a back rigid supporting structure, a lateral flexible supporting structure, a lateral rigid supporting structure, a stress state testing sensor and a strain measuring instrument, wherein the back flexible supporting structure is used for flexibly supporting the back surface of the large-aperture reflector; the back rigid supporting structure is used for rigidly supporting the back flexible supporting structure; the lateral flexible supporting structure is used for flexibly supporting the side surface of the large-aperture reflector; the lateral rigid supporting structure is used for rigidly supporting the lateral flexible supportingstructure; the stress state testing sensor is used for monitoring stress states of the back surface and the side surface of the large-aperture reflector; the strain measuring instrument is used for recording monitoring data of the stress state test sensor. Monitoring of the stress state is realized through the stress state testing sensor, dependence on experience of mature technicians is not needed, and a standardized process adjustment scheme is suitable for being formed.
Description
technical field [0001] The invention relates to the technical field of optical equipment, in particular to a device and method for processing and adjusting a large-diameter reflector. Background technique [0002] Due to its large weight, the surface shape of large-aperture mirrors is easily affected by many factors during processing, among which the self-weight and the preload of the support have a greater impact on the surface shape of large-aperture mirrors. Before and after the large-aperture mirror is coated, due to the inconsistency of the constraint state of the large-aperture mirror, multiple support adjustments are required, and the interference surface shape detection method is used to ensure that the surface shape accuracy is within the design allowable range. However, the parameter adjustment of the assembly process of large-aperture mirrors requires the experience of mature craftsmen, and it is not suitable to form a standardized process assembly plan. This pro...
