Description
Technical Field
The invention relates to a firearm calibration device, in particular to a firearm laser calibrator, a calibration method, a gun calibration method and a method for determining a bore axis target point.
Background
Units, whether firearm manufacturing plants, armies, or police units, require calibration of the firearm prior to use. The prior firearm calibration device has huge and very complex structure, and is mostly installed indoors for precisely calibrating firearms for production and maintenance. In contrast, the gun units for base lines and the like do not have the conditions for using such large calibration equipment. The gun calibration work is basically to calibrate by analyzing the impact point after a large number of bullet test shots are performed in a shooting range. The gun calibrating mode not only causes great consumption of bullets and abrasion to guns, but also is greatly influenced by subjective factors such as personal habits of shooters, and is not beneficial to accurate and large-batch calibration of the guns.
Besides high cost, the existing mechanical or photoelectric gun calibrating equipment has the defects of easy damage, inconvenient operation and the like. In order to solve the problems of high manufacturing cost, easy damage and inconvenient operation of special equipment, some small gun calibrating instruments exist at present, such as a patent CN201155941Y, CN202361891U and the like, which all use a mode of inserting a laser into a muzzle and utilize laser propagated in a straight line to replace a bullet flight trajectory for gun calibrating. The point of irradiation of the laser light on the target is considered as the impact point of the firearm. However, the actual gun calibration work uses a distance of 100 meters as a basic gun calibration test distance, and the existing gun calibration instruments cannot actually realize the accurate gun calibration purpose at all. For example, when shooting a 95 rifle, the primary aim of the shooter is to "target-sight-target" along a line, which is the "aim baseline". If this method of using a laser as an extension of the bore axis to indicate the impact point is used, and the perpendicular distance of the sight from the bore axis is temporarily not considered, it is equivalent to overlapping the sight base line with the bore axis. In practice, 95-type rifle fires with a bullet at an initial velocity of 900 m/s, and a flight distance of 100 m takes 0.11 seconds. It can be found from rough calculation that the bullet descends by a distance of (9.8 x 0.11) in the period of time under the condition of horizontal shooting without considering complicated factors such as air resistance and gyroscopic effect 2 ) 2=0.06 meters, i.e. 6cm. This corresponds to having shifted the actual impact point down from the center of the aiming 10 rings to 9 rings. This is an unacceptable error for a precision shot. It is conceivable that if the actual gun calibration distance is 200 meters, only the theoretical deviation thereof is up to 24cm. The deviation will be greater if the deceleration of the bullet due to the air resistance during the flight is considered.
Therefore, it is obviously not preferable to calibrate the gun in such a way that the irradiation point of the laser on the target is regarded as the impact point of the firearm. Then, the laser is moved up on the irradiation point of the gun target to compensate the descending height of the gravity acting on the bullet, whether the accurate gun calibration can be realized or not is judged, and the answer is also negative. This is because the laser generator itself is limited by the installation conditions, and the axis of emission of the laser beam and the axis of the laser generator itself are difficult to ensure coaxially. The deviation ensures that when a laser generator rotates along the axis of the laser generator for one circle, the irradiation track on the curtain wall outside 100 meters can form a circular ring, and when the deviation is large, the diameter of the circular ring can even reach 1-2 meters. Because the state that the laser generator is directly inserted into the gun barrel is uncertain, the gun calibrating device which is used for simplifying and simulating the impact point by using the laser irradiation point is extremely large in final error and has no practicability, and the gun calibrating device cannot be used for solving the actual gun calibrating work of the base layer convoy.
