Description
Technical field
The utility model relates to calibrating installation technical field, particularly relates to a kind of small arms precision fire calibrating installation.
Background technology
Before ball firing, must the small arms used be calibrated; Good small arms (rifle, mobile phone, sniper rifle, light machine gun etc.), the relation between the mean trajectory of its bullet, axis of bore, sight line three is relatively fixing.
So-called mean trajectory, namely under the meteorological condition of standard, repeatedly shoots, the mean trajectory of bullet, and its form of expression is often apart from a point on gun certain distance target.For 95 formula automatic rifles, its mean trajectory shows as a point on distance gun 100 meters of targets, claims this point to be center of impact.Why be center of impact, even if be because gun are under strict fixing prerequisite, the point of impact of bullet is also relevant with multiple factor, such as: the difference of explosive payload, the quality of bullet and shape difference, the difference of meteorological condition (temperature, air pressure, air humidity, local acceleration of gravity), wind speed and wind direction etc. in the processing differences of bore, bullet cartridge case.
So-called sight line, refers to the straight line that central point, foresight top determines with aiming breach center of top point (95 formula automatic rifles are the center of circle of scale small sircle hole) or the optical axis of optical sight.The intersection point of sight line and target, is referred to as aiming point.For 95 formula automatic rifles, in the distance of 100 meters, gun, arranging a target, center of impact is some A, and the intersection point of axis of bore and target is some B, and aiming point is some C.Under normal circumstances, some A does not overlap with some B, but relative position is fixed.
So-called calibration, is exactly by the height of foresight and the adjustment in direction, makes aiming point C and center of impact A keep the relation of fixing, such as, to the calibration of 95 formula automatic rifles in the distance of 100 meters, normally allow aiming point C overlap with center of impact A.So, the intersection points B of axis of bore and target and the position of aiming point C are also just relative fixing, so also have use optical equipment, the mode finding the intersection points B of axis of bore and target calibrates gun.
Small arms calibration has two kinds of modes: use optical equipment calibration and live shell calibration.Owing to using the systematic error of optical equipment calibration comparatively large, operation is also inconvenient, and the gun after optical equipment calibration, can must use after live shell inspection, so the most effective the most frequently used small arms calibrating mode is live shell calibration.
In live shell calibration process, the work finding center of impact is the work of calibrating the most basic most critical again.Be calibrated to example with 95 formula automatic rifles, usually under standard meteorological conditions, launch 4 bullets on the target of 100 meters by sharpshooter, obtain center of impact, then adjust foresight, aiming point is overlapped with center of impact.Launch by so-called sharpshooter the calibrating mode that 4 bullets are averaging point of impact to have the following disadvantages: artificial disturbance is large, and calibration accuracy is low, inefficiency, gun calibration relies on greatly so-called sharpshooter.
Chinese utility model patent number discloses universal calibration instrument for gun of military police squad for ZL200520000981.6, and it exists obviously not enough: adopt between firearms and prover and be rigidly connected, kick during shooting can produce a turning torque; And this patent effectively could not eliminate the turning torque that firearms kick produces, it is made at least to produce two adverse consequences: one is reduce fire accuracy, and then affects calibration accuracy, and two is the parts easily damaging prover.Simultaneously, this patent has significantly not rigorous statement, as: " realize gun barrel central shaft, mechanical aiming baseline, optical laying axle, electronic aiming axle four axle be coaxial ", because above four axles are not at conplane straight line, may be not coaxial, therefore, there is deviation in the understanding of this patent to calibration essence.
