Problems solved by technology

The traditional assembly and adjustment device cannot guarantee the consistency of mass assembly process, the efficiency is low, and it cannot meet the needs of multi-layer nesting adjustment. At the same time, it is easy to cause deformation of large-sized ultra-thin lenses, and the assembly accuracy cannot be guaranteed.

Embodiment Construction

[0021] refer to Figure 12 As shown, the principle of the assembly and adjustment device: during the assembly and adjustment process, the lens barrel to be assembled is hoisted above the spider hub through the hoisting plate assembly. The light emitted by the point light source is reflected by the parabolic mirror to form a parallel beam. After being blocked by an aperture of a specific size, only light that matches the size of the lens barrel to be tested can enter the hub assembly. The light beam is reflected by the lens barrel and focused on the imaging plane of the camera placed 5.25 meters above. The system first measures the spot position of the reference mirror, then detects the pre-focus and back-focus spots of the lens barrel to be tested, compares the two and calculates the angle and position error. Then adjust the relative angle and position of the hub assembly and the new lens barrel until both focus on the same point. The horizontal and vertical positions of th...

Abstract

The invention discloses a multi-layer nested X-ray focus lens main power control assembling and adjusting device, and belongs to the technical field of X-ray focus lens machining. The assembling and adjusting device is used for guaranteeing the consistency of large-batch assembling; and the assembling and adjusting efficiency is improved while low deformation of a large-size ultrathin lens is guaranteed. A lifting disc assembly, a hub adjusting assembly and a light source assembly are sequentially installed on a support from top to bottom; a camera adjusting assembly is arranged over the lifting disc assembly; the lifting disc assembly is used for lifting a lens cone between the camera adjusting assembly and the hub adjusting assembly; parallel light emitted by the light source assembly is screened by the hub adjusting assembly and then is focused on a camera imaging plane of the camera adjusting assembly after being reflected by the lens cone; and the lens cone or a hub of the hub adjusting assembly is adjusted according to the position of a light spot formed by a camera. According to the invention, non-standardization caused by manual operation is avoided; consistency and reliability of assembly and adjustment are realized; low deformation of the lens in the assembly process is ensured; manpower is saved; and the overall assembly and adjustment efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of X-ray focusing mirror processing, and in particular relates to a multi-layer nested X-ray focusing mirror active force control and adjustment device. Background technique [0002] In order to study and observe new phenomena of high-energy radiation from celestial bodies such as black holes and neutron stars, observatories and space centers in many countries and regions led by the United States have launched more than ten X-ray astronomical satellites into space. In 1952, German physicist Hans Wolter designed three kinds of Wolter-type X-ray focusing telescopes with grazing incidence satisfying the Abbe sine condition, called Wolter III III focusing telescopes. The Wolter-Ⅰ X-ray telescope is composed of a parabolic internal reflector and a hyperbolic internal reflector. Its advantage is that it can be nested in multiple layers, which is conducive to weak source observation. It is also the most common type...
