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