[0003] At present, when processing and inspecting large-aperture space mirrors with back blind holes, most of them use indium steel components to be bonded in the back blind holes, and then transferred to the mounting bracket through flexible support elements. Due to mechanical assembly and adjustment To realize the control of the support force and contact state of the mirror, it is impossible to know the actual force and distribution state of the support device on the mirror, and it is also difficult to accurately control the size of the contact force, and it is difficult to meet the high-precision requirements of large-aperture space mirrors. The need for heaven and earth consistency testing

The invention discloses a contact-force controllable-type reflecting mirror detection floating support. The support comprises a rubber gasket, a surface force sensor, a floating head, a top rod, a balance lever, a mandrel, a bearing pedestal, a hinge pin, a bearing, a support bar, a cylinder seat, a small shaft, a joint, a cylinder installing plate and a cylinder. The cylinder drives the top rod through the balance lever and drives the floating head and the rubber gasket to provide a support force for a reflecting mirror. The support has advantages that the surface force sensor installed between the rubber gasket and the floating head can detect a contact force size and distribution of floating support to the reflecting mirror; an air pressure size of the cylinder is accurately controlled and a support force size can be controlled, and force repeatability is high; the balance lever and the cylinder are installed on the bearing pedestal along with the mandrel through the bearing and can be freely rotated in the bearing pedestal, and the top rod automatically maintains a vertical and upward direction, which is convenient to provide a vertical and upward support force for the mirror.
Description
technical field [0001] The invention relates to the field of optical processing and detection, in particular to a floating support device for detecting a reflective mirror with controllable contact force, which is especially suitable for detecting a large-diameter reflective mirror. Background technique [0002] The specific stiffness of the space large-aperture mirror is increased after being lightened, but the overall rigidity is reduced, and it is easy to deform under the action of external force. Since space applications require that the precision of the mirror has a good consistency between heaven and earth, this requires that the support force of the mirror must be precisely controlled when the mirror is processed and tested on the ground, so that the mirror deforms as much as possible under the action of gravity and support force. It may be as small as possible to reduce the influence of this deformation error on the surface shape detection of the mirror. [0003] At...
