Embodiment

[0076] 1 Optical sighting prism level detection

[0077] (1) Press image 3 As shown, the height of 6 platforms is about 2.5 meters. Align the optical axis of the autocollimator 5 to the local vertical direction, and the alignment accuracy is not greater than 3".

[0078] (2) Adjust the regular hexahedron 4 with the autocollimator 5 to keep the regular hexahedron 4 horizontal.

[0079] (3) Set up the first theodolite 2 at an elevation angle of 30.9337° to the center of the aiming prism 1 of the platform 6 about 3.3 meters away from the platform 6, and set up the second theodolite 3 on a tripod at an elevation angle of 16.6917° at an elevation angle of 16.6917° at a distance of about 4.8 meters from the platform 6 The aiming prism 1 center. After the two theodolites are aligned with the aiming prism 1, the position of the theodolite is fine-tuned so that the optical axes of the two theodolites after aiming at the aiming prism 1 are in the same plane. After adjustment, fix the posit...

Abstract

A method for detecting optical alignment prism mounting accuracy deviation calibration of a platform system includes a non-levelness calibration method of an alignment prism and a non-perpendicularity calibration method of the alignment prism, optical alignment prism mounting accuracy deviation calibration of the platform system can be detected by the aid of a regular hexahedron, an autocollimator and two theodolites, and the technological gap of the method is filled. A large swinging angle of a detected object is allowed, namely, a large elevation difference exists, a ground horizontal plane serves as a reference, the reference does not need to be converted through a standard hexahedron, the detecting accuracy of optical alignment prism mounting accuracy deviation calibration is improved, and the method is simple to operate, high in efficiency and detecting accuracy and easy to implement.

Description

Technical field [0001] The invention belongs to the technical field of measurement, and relates to an installation error calibration method of an optical sighting prism for a spacecraft platform system. Background technique [0002] The gyro stabilized platform 6 is usually equipped with an optical sighting prism 1. The aiming prism 1 is used as the reference for the initial aiming of the missile, and its installation accuracy will directly affect the aiming of the missile before take-off, thereby affecting the accuracy of the missile's landing point. [0003] During the manufacturing process of the platform 6, under the action of various screening tests and mechanical environments, the stress change of the platform structure in the platform 6, the temperature coefficient mismatch between the prism component and the platform, and the stress release of the installation part caused the aiming The deviation of the installation accuracy of the prism 1 changes. When the horizontal fix...
