Gun calibration device and method

Abstract

The invention discloses a gun calibration device and method. The gun calibration device includes a gun holding platform and a laser device which are used for calibrating firearms, the gun holding platform is provided with front and rear quick clamping mechanisms, an automatic rifle is fixed through the quick clamping mechanisms, the front clamping mechanism is provided with a height and directionadjusting mechanism, the aiming action on a gun can be completed; and a sighting telescope laser device is arranged on the sighting telescope clamping seat of the automatic rifle, and a bore of the automatic rifle is internally provided with a bore shaft laser device. According to the gun calibration device and method, through a dual-laser calibration mode of the bore shaft laser device and the sighting telescope clamping seat, gun calibration can be completed accurately without conducting firing practice, the error caused by the individual difference of marksmen is avoided, the site is simplified, the live ammunition is saved, and the operational efficiency and safety of gun calibration shooting are improved; and the inaccurate firearms are fixed through the portable gun holding platform,influence factors of artificial gun holding are eliminated, and stability of gun holding is realized.

Description

technical field [0001] The invention relates to a method for correcting the accuracy of firearms, in particular to a gun calibration device and a gun calibration method, and belongs to the professional field of military equipment use and support. Background technique [0002] Gun accuracy calibration is the most frequently performed technical support work in the use and support of military equipment. It is an important technical service to ensure the effectiveness of guns. ) and the axis of the bore (increased the height of the rear sight and the front sight), and the structure of the front sight has been increased from a one-stage movable type to a multi-stage movable type, resulting in easy deterioration of the sight line accuracy, decreased shooting accuracy, and even chaos in the sight line . As a result, emerging firearms require more frequent calibration and higher precision. [0003] There are two main methods of gun calibration at the grassroots level of the army: ...

AI Technical Summary

Problems solved by technology

Theoretically, the calibration and verification can be completed with just one shooting and adjustment. However, the actual shooting calibration is restricted by factors such as climate (wind direction), visibility (sunny and cloudy), shooting range conditions, and the shooter’s personal experience level. Multiple shootings are required. calibration to complete

Time-consuming, labor-intensive, ammunition-intensive, imprecise, unsafe

[0005] The instrument calibration methods that have appeared in recent years include optical sight correction method and laser aiming point correction method. The optical sight correction method is mainly used for the correction of gun sights, and it cannot solve the problem of the mechanical sight line correction composed of the rear sight and the front sight.

Problems in the single laser ray correction method: first, the laser line is collimated and cannot coincide with the ballistic trajectory; second, the laser is positioned and fixed by the axis of the gun bore and the gun, and the positioning accuracy is caused by the different degrees of wear and tear of the gun bore during use. The third is that the operation mode of the calibration remains unchanged, and human factors affect the calibration accuracy

Therefore, live ammunition verification is required after laser calibration, and it is difficult to complete the precise calibration task only with laser single-line calibration
