Installation adjusting device suitable for combination optical window testing

Abstract

The invention discloses an installation adjusting device suitable for combination optical window testing. The installation adjusting device comprises a base assembly, a rocker assembly connected with a product to be tested, a fine-adjusting assembly and a connection rod. A sliding bearing formed by an azimuth shaft and an azimuth base of the base assembly can achieve azimuth rotation, a fixing base on the sliding bearing and two rotating bases are distributed on the upper end surface of an upper bottom plate in a triangular mode, the fine-adjusting assembly is provided with a thread pair and a sliding pair and fixedly connected with the fixing base, the rocker assembly is a hollow-out #-shaped framework, rotating blocks at two ends of a long rod on one side of the rocker assembly are respectively hinged to two rotating bases on the base assembly in parallel mode, a rotating block at the center of a long rod on the other side of the rocker assembly is hinged to one end of the connection rod, and the other end of the connection rod is hinged to the rotating block on the fine-adjusting assembly, so that a sliding block connection rod mechanism in the installation adjusting device is formed, and a knurled nut pushing block in the thread pair can adjust the pitching dip angle of the rocker assembly in fine mode. The installation adjusting device solves the problem of installation adjusting in combination optical window resolution ratio testing and has the advantages of being fast in installation, small in light shielding, simple in installation adjusting and the like.

Description

technical field [0001] The invention belongs to the field of optical testing, and mainly relates to an installation adjustment device used in optical testing, in particular to an installation adjustment device used in resolution testing of combined light windows. Background technique [0002] The combined light window is used to provide effective protection for the distributed aperture photoelectric system, adapt to the impact of aerodynamic heating and optical effects caused by high-speed flight, and can withstand the erosion of high-speed sand and dust and erosion of raindrops. as attached figure 1 As shown, the combined light window is composed of a plurality of large flat glass 1 and a metal frame 2, which looks like a transparent roof. The shape of the flat glass 1 is irregular, forming unequal angles in space. The metal skeleton 2 is a frame-shaped structure, and the flat flange at the bottom is the system installation interface. The overall size reaches 500×800×500 (...

AI Technical Summary

Problems solved by technology

Due to the use of worm gears, this kind of device has high manufacturing costs, and can only be adjusted around one axis, making it difficult to install and align the combined light window, and there is also the problem of light shading

In foreign countries, although there are similar combined light windows, there is no report about the installation and adjustment device for the combined light window test.
