Precise shooting calibration device of small arms

Abstract

The invention relate to the technical field of calibration devices, in particular to a precise shooting calibration device of small arms. The device comprises a bracket, a horizontal disc, a rail vertical plate, a base and a gun support plate for clamping the small arms, wherein the horizontal disc is horizontally arranged on the bracket through a horizontal adjusting mechanism; the base is vertically arranged on the horizontal disc; the other side surface of the rail vertical plate is rotationally connected with the base through a pitching adjusting mechanism; a rail gap adjustable rail device is arranged on one side surface of the rail vertical plate; and the gun support plate is slidingly arranged on the rail device. The device reduces radial runout of the arms, reduces the damage of recoil to the device, eliminates the influence of the recoil process on the shooting precision, realizes precise solution of average impact point only through aiming, performs precise calibration to eliminate the dependence of the arms calibration on excellent shooters, improves the calibration precision, reduces the labor intensity of calibration work, and promotes the calibration efficiency.

Description

technical field [0001] The invention relates to the technical field of calibration devices, in particular to a precision shooting calibration device for light weapons. Background technique [0002] Before shooting live ammunition, the light weapons used must be calibrated; for a good light weapon (rifle, mobile phone, sniper rifle, light machine gun, etc.), the relationship between the average trajectory of the bullet, the axis of the bore, and the line of sight is relatively fixed. [0003] The so-called average trajectory refers to the average trajectory of the bullet after multiple shots under standard meteorological conditions. Its manifestation is often a point on the target at a certain distance from the gun. Taking the Type 95 automatic rifle as an example, its average trajectory is represented as a point on the target 100 meters away from the gun, which is called the average impact point. The reason why it is the average impact point is that even if the gun is stri...

Problems solved by technology

The calibration method of firing 4 rounds by a so-called excellent shooter to find the average impact point has the following disadvantages: large human interference, low calibration accuracy, low work efficiency, and the gun calibration relies heavily on the so-called excellent shooter

[0008] The Chinese Utility Model Patent No. ZL200520000981.6 discloses a universal calibrator for guns used by military and police squads, which has obvious shortcomings: a rigid connection is adopted between the firearm and the calibrator, and the recoil force during shooting will produce a turning moment; The patent fails to effectively eliminate the overtur
