Optical calibrator for multi-barrel axis parallelism of artillery

Abstract

The invention discloses an optical calibrator for the multi-barrel axis parallelism of artillery, and relates to the technical field of calibration for multi-barrel artillery. The optical calibrator comprises bullet-shaped axial lasers, a calibration assembly, a measurement assembly and a total reflection prism group, wherein the bullet-shaped axial lasers are respectively installed in chambers ofa reference barrel G0 and a measured barrel G1 of the artillery and emit laser beams which are overlapped with barrel axes of the artillery, the total reflection prism group and corresponding prismsin the calibration assembly and the measurement assembly to enable quadrangular optical paths to be coplanar, the bullet-shaped axial laser L2 emits a laser beam, the laser beam is reflected to a reticle of a focal plane of an angle measurement telescope w2 by a semi-transmitting and semi-reflective prism F to form a light spot, the non-parallelism deviation between the reference barrel and the measured barrel can be judged through comparing the overlap ratio of the light spot with a light spot, which is reflected to the angle measurement telescope w2 by an optical path, from the axial laser L1, the axis of the measured barrel is adjusted until the two light spots are overlapped, and thus the calibration for the parallelism of the two barrels is completed.

Description

technical field [0001] The invention relates to the technical field of axis calibration of artillery barrels, in particular to an optical calibrator for parallelism of axes of multiple barrels of artillery. Background technique [0002] The main purpose of the multi-barrel design of the artillery is to increase the density of the barrage, thereby increasing the probability of killing, and the parallelism between the barrels is the core indicator to ensure the shooting effect. Whether it is the factory inspection of the artillery manufacturer, Or use the daily training and maintenance of the troops, the parallelism of the multi-body tube axis must be calibrated. The current detection and calibration methods still use the method of aiming at the long-distance target with the calibration mirror. This method needs to level the chassis supporting the firepower system first, then return the height of the artillery direction to zero, and then repeatedly adjust the target to be perp...

Problems solved by technology

The current detection and calibration method still uses the method of aiming at the long-distance target with the calibration mirror. This method needs to level the chassis supporting the firepower system first, then return the height of the artillery direction to zero, and then repeatedly adjust the target to be perpendicular to the reference axis. location, there are problems such as complicated adjustment process, heavy equipment, and many restrictions by the site and environment, which is time-consuming and labor-intensive, and the calibration efficiency is low
