Method for gluing two seams of spatial reflector

Abstract

The invention provides a method for gluing two seams of a spatial reflector, relates to the technical field of spatial optical remote sensing, and aims at solving the problems of small positioning precision, non-uniform glue layer thickness, reduction of surface figure accuracy of the spatial reflector caused by residual stress after solidifying of a glue layer, and unstable stress distribution in the existing method of gluing the spatial reflector and an embedded part through three jackscrew. The method is that glue coats the lower side of the inner hole wall of the spatial reflector; the upper side of the inner hole wall of the spatial reflector is in match with a large seam of a double-seam adhering tool; meanwhile, the glue coats the outer wall of the embedded part; the inner wall of the embedded part is in match with a small seam of the double-seam adhering tool to finish the adhering of the spatial reflector and the embedded part; the large seam and the small seam of the double-seam adhering tool are processed based on the same reference, so that the coaxiality of the two seams can be ensured, and the uniformity of the glue layer thickness can be greatly improved; the glue layer is uniform in thickness; the residual stress is small after the solidifying of the glue layer; therefore, the surface figure accuracy of the spatial reflector can be fully ensured. The method is simple and reliable to operate.

Description

technical field [0001] The invention relates to the technical field of space optical remote sensing, in particular to a method for gluing a space reflector with double seams. Background technique [0002] The surface shape accuracy requirement of the space mirror 1 is very high, and its surface shape accuracy directly affects the imaging quality of the space camera. The space reflector 1 is usually made of glass or ceramic material, and the characteristics of the material make the space reflector 1 unable to be threaded, so that the thread cannot be used to connect and fix the inlay 5 . The space mirror 1 and the inlay 5 are usually connected by epoxy resin. However, due to the uneven thickness of the adhesive layer 2 bonded between the space mirror 1 and the inlay 5, the space mirror 1 Greater stress is generated between the mosaic 5 and the surface shape accuracy of the space mirror 1, thereby reducing the imaging quality of the space camera. [0003] At present, the glu...
