Firearm laser calibrator, method for demarcating firearm laser calibrator, method for calibrating firearm and method for determining target point of bore axis

Abstract

The invention discloses a firearm laser calibrator, a method for demarcating the firearm laser calibrator, a method for calibrating a firearm, and a method for determining the target point of the boreaxis. The firearm laser calibrator comprises an inserted rod, a laser fixing frame and a laser generator, wherein the inserted rod is in a straight-handle rod shape, the diameter of the inserted rodis slightly less than the sunny side inner diameter of a gun barrel inner rotation line of a calibrated firearm, so that the inserted rod is smoothly inserted and connected into a gun barrel from a gun muzzle; the laser fixing frame includes a positioning cylinder for fixing the laser generator and an inserted rod positioning piece arranged on the upper side of the positioning cylinder, and the front end of the inserted rod is fixedly connected to the inserted rod positioning piece; and the laser generator is arranged in the positioning cylinder of the laser fixing frame. By means of the firearm laser calibrator, the purpose of calibrating the firearm can be achieved, and the accurate positioning of the extension line on the bore axis can also be achieved, the firearm laser calibrator is simple in structure, and convenient to use, the calibration work of the general light weapons such as rifles without live firing can be achieved, the calibration process is fast and accurate, and the firearm laser calibrator is very suitable for the use of the gun application unit of a basic level which lacks the special gun calibrator equipment.

Description

Technical field [0001] The patent of the invention relates to a firearm calibration device, specifically a firearm laser calibrator, a method for calibrating and calibrating the gun and determining the target point of the barrel axis. Background technique [0002] Whether it is a firearm manufacturing factory, the army, or the public security, the firearms need to be calibrated before they are used. The existing firearm calibration device has a huge structure and is very complicated, and most of them are installed indoors for precise calibration of firearms produced and maintained. For units with guns such as grassroots companies, they do not have the conditions to use such large-scale calibration equipment. Its gun calibration work is basically carried out after a large number of bullets are tested at the shooting range, and then calibrated by analyzing the impact point. This gun calibration method not only causes a large amount of bullet consumption and wear of the firearms, ...

AI Technical Summary

Problems solved by technology

[0005] One of the purposes of the present invention is to provide a firearm laser calibrator to solve the problems of existing firearm calibrator with complex structure, unchanged operation, low calibration accuracy and large error

[0006] The second purpose of the present invention is to provide a marking method for determining the extension line of the bore axis, so as to solve the problem that the determination of the position of the extension line of the bore axis on the target cannot be realized at present
