Heat dissipation flexible supporting leg for assembling and adjusting large space camera

Abstract

The invention discloses a heat dissipation flexible supporting leg for assembling and adjusting a large space camera, and belongs to the technical field of ground integration of space cameras. According to the invention, the defects of multiple parts, complex structure, low assembly repeatability and the like of an existing heat dissipation structure are overcome, and the problem that influence oftool thermal deformation on the imaging quality of the system in the adjustment process of a large camera cannot be effectively overcome. A first mounting plate and two second mounting plates are correspondingly and fixedly connected through two groups of supporting rod structures, each supporting rod structure comprises a supporting frame and two connecting plates, the supporting frames are arranged in a rectangular structure, and two end plates of each supporting frame are correspondingly and fixedly connected with the first mounting plate and the corresponding second mounting plate throughthe connecting plates. Rigidity weakening is carried out on the two sets of supporting rod structures of the supporting legs respectively, limited release is carried out on the spatial freedom degree, and the flexible heat dissipation effect is achieved.

Description

technical field [0001] The invention relates to a heat-dissipating flexible outrigger for mounting a large-scale space camera, and belongs to the technical field of ground integration of space cameras. Background technique [0002] When the long focal length and large-aperture off-axis three-mirror camera is installed and adjusted on the ground, the influence of environmental temperature changes will cause the deformation of the camera assembly and adjustment tooling, and the thermal stress generated by the thermal deformation will be directly transmitted to the camera, affecting the surface quality and relative position accuracy of the optical components of the camera, resulting in Camera image quality degrades. [0003] In the prior art, the main support structure for large-scale space remote sensors adopts the Hexapod support form, including 6 rods and 12 connection points, of which 6 points are supported by spherical joints, and 6 points are supported by Hooke hinges.
