Abstract

A split-type space optical remote sensor focusing structure, comprising: at least three cross-roller units to increase the bearing capacity of the focusing mechanism, split-type slider connectors to reduce assembly internal stress and deformation, and to provide flexibility in the corresponding direction. The third-level flexure joint; the cross-roller units are evenly distributed around the movement axis of the focusing mechanism and along the circumferential direction, and are connected to the fixed seat by screws; The position corresponding to the slider of the cross-roller unit is in close contact with the slider of the cross-roller unit; the third-stage flexure joint and the split slider connecting piece are fixedly connected by screws, and the third-stage flexure joint is fixed by screws. Made of elastic sheet. Under the premise of satisfying the launch impact, it is of great practical significance to achieve a focusing mechanism that is as light as possible, high precision, high stability, good processing and assembly manufacturability for improving the imaging quality of large space optical remote sensors.

Description

technical field [0001] The invention belongs to the technical field of remote sensor focusing, and in particular relates to a split space optical remote sensor focusing structure. Background technique [0002] In order to ensure the on-orbit imaging quality of the space optical remote sensor and eliminate the defocusing phenomenon caused by various reasons, a focusing mechanism needs to be set up. In recent years, with the continuous development of space detection technology, more stringent requirements have been put forward for focusing mechanisms: large-scale, light-weight, high-precision, high-rigidity and high-stability. [0003] At present, there are many ways to realize the focusing mechanism. Among them, the most commonly used structure is the use of motor drive, ball screw drive, and linear guide guide, and most of them are guided by two guide rails. For conventional small-size focusing mirrors, The focusing mechanism of this structure can meet the task requirements...
