Problems solved by technology

Due to the particularity of its structure, there is no direct assembly and adjustment reference in the assembly and adjustment process, which is easy to introduce large clamping stress and bonding stress, and it is difficult to ensure optical accuracy, sealing requirements and electromagnetic shielding requirements at the same time
Aviation optical windows generally provide assembly and adjustment references through fixed face-to-face cooperation, and use plugs and pressure plates to restrict the degree of freedom of assembly and adjustment. The stress of assembly and adjustment is large, resulting in a decrease in optical performance, and it is difficult to ensure sealing performance and electromagnetic shielding performance at the same time

Abstract

The invention relates to a device and method for installing and adjusting a low-stress conductive seal of an aviation light window. By using instruments and equipment such as an altimeter, a precision electric control adjustment table, and a self-collimating light tube, the light window is installed and adjusted with a reference tool, a light window, etc. Support tooling and other special process equipment and composite adhesive layer can quickly establish the installation and adjustment benchmark of the aviation light window, improve the installation accuracy, reduce the clamping stress and bonding stress, avoid the installation and adjustment stress, and ensure the sealing performance of the aviation light window. The optical performance is guaranteed while the electromagnetic shielding performance is achieved, which greatly improves the installation and adjustment efficiency and quality of aviation light windows.

Description

technical field [0001] The invention belongs to the technical field of optical-mechanical assembly and adjustment, and relates to a low-stress conductive sealing assembly and adjustment of aviation optical windows, which can quickly establish an assembly and adjustment reference, improve the accuracy of assembly and adjustment, and avoid assembly and adjustment stress, and can ensure the sealing performance of aviation optical windows, Electromagnetic shielding performance while ensuring optical performance. Background technique [0002] The aviation optical window is the optical window of the airborne photoelectric detection system. The quality of its installation and adjustment directly determines the optical performance, sealing performance and electromagnetic shielding performance of the system. Due to the particularity of its structure, there is no direct assembly and adjustment reference during the assembly and adjustment process, which is easy to introduce large clamp...
