Suspension type precise adjustment device for poses of multi-layer nested reflector

Abstract

The invention discloses a suspension type precise adjusting device for the pose of a multi-layer nested reflector. The device comprises a reflector, a front radial plate, a bottom frame, a bottom cover plate, a supporting plate, a stand column, a two-dimensional platform assembly, a front radial plate fixing assembly, a front radial plate supporting assembly, a pose measuring assembly, a pose adjusting assembly and a balance weight adjusting assembly. Wherein the pose adjusting assembly is composed of an adjusting module, a piezoelectric ceramic actuator, a pose adjusting rod and a flexible adsorption head; the counterweight adjusting assembly is composed of an adjusting module, a fixed pulley, a counterweight block, a counterweight adjusting rope and a flexible adsorption head. The pose measuring assembly is composed of a measuring support and a non-contact sensor. The two-dimensional platform assembly is composed of corresponding motion modules and various supporting plates. The supporting plate is supported by the front radial plate supporting assembly and fixed by the front radial plate fixing assembly. The pose of the reflecting mirror is measured by the pose measuring assembly, and after the reflecting mirror is balanced by the counterweight adjusting assembly, the pose adjusting assembly and the two-dimensional platform assembly adjust the pose of the reflecting mirror. The device is convenient to operate, flexible adsorption of the reflecting mirror can be achieved, the dead weight of the reflecting mirror can be counteracted, integral moving centering of the reflecting mirror is achieved, irreversible deformation of the front radial plate before and after acting force is applied and unloaded is reduced, and finally the assembling and adjusting precision of the multi-layer nested reflecting mirror is improved.

Description

technical field [0001] The invention belongs to the field of precise adjustment of optical devices, and in particular relates to a suspension type precise adjustment device for the pose of multi-layer nested reflecting mirrors. Background technique [0002] The Wolter-I multi-layer nested mirror is the main component of the X-ray grazing incidence optical lens. Due to its high focusing efficiency, low space background noise and large optical gain, it is used for astronomical observation technology, pulsar navigation, deep space exploration, etc. The high-efficiency and high-signal-to-noise ratio observation of space targets in the mission provides the possibility, so it has become the object of vigorous research and development abroad in recent decades. However, domestic research on multi-layer nested mirrors is still in its infancy. The entire manufacturing process of multi-layer nested mirrors involves a series of high-standard processes such as processing, assembling, and...

Problems solved by technology

However, domestic research on multi-layer nested mirrors is still in its infancy. The entire manufacturing process of multi-layer nested mirrors involves a series of high-standard processes related to processing, assembly, and testing, especially for the one-piece electroformed nickel-type multi-layer mirror. In the process of assembling and adjusting mirrors nested in layers, the relevant domestic traditional assembling and adjusting methods in the past have problems such as difficult control of assembling and adjusting errors and unsatisfactory assembling and adjusting accuracy, because the thickness of the mirror is only tens to hundreds of microns, which is very thin. It is difficult to control the amount of deformation of a single layer; and for the number of nesting layers, from a few layers to hundreds of layers, it is difficult to guarantee the accuracy of the centering of the multi-layers. These factors cause the multi-layer nesting reflection after the final adjustment The results of poor optical imaging and low angular fraction of the mirror
