Description
Technical field
The utility model relates to a kind of error measuring means, is specifically related to a kind of high accuracy ballistic deflection system for measuring quantity.
Background technology
The intrinsic shooting departure of firearms is divided into jumps angle and bias current two parts.
Jumped in angular measurement at firearms in the past and used quadrant and coldly penetrated mirror, because quadrant and cold mirror of penetrating exist constant error, when causing measuring, produced systematic error and random error.Due to firearms, to jump angle value inherently very little, generally-5 ' to+5 ' scope, if so jump in angular measurement examination and there is larger measure error, the authenticity of so jumping Angle Measurements is suspectable.The results showed, original method is jumped angle test error and is about 30 ".
In the past in bias current is measured, give " lens by identical direction ", " in opposite directions method " two kinds shooting scheme, " lens by identical direction " needs to process one, left-handed rifle, and " in opposite directions method " needs two dextrorotation rifle correlation, the financial cost of processing left-handed rifle is very high, and the shooting place of " in opposite directions method " is difficult to find.All there is very large difficulty in these two kinds of shooting schemes, lack operability, the results showed, original method bias current test error is about 0.1mil in force.
Utility model content
The utility model provides a kind of and has high accuracy, firearms ballistic deflection system for measuring quantity easy and simple to handle, and solve the difficult problem that measurement jumping angle and bias current time error are in the past comparatively large, lack operability, reduce measurement cost, efficiency is measured in raising.
The technical solution of the utility model is:
A kind of high accuracy ballistic deflection system for measuring quantity, described measuring system comprises as lower device:
Shooting platform, has height, two, the left and right free degree regulates, and gun barrel is fixed on shooting platform;
Laser alignment device, is arranged on gun barrel, is front inserting or shell type;
Directive demarcates target, is provided with coordinate grid;
Departure receiving target, is provided with coordinate grid, and directive is demarcated target and is arranged between shooting platform and departure receiving target.
Preferably, described laser alignment device is laser school rifle device, and comprise 5.8mm, 7.62mm, 12.7mm, 14.5mm tetra-kinds of bores, laser range contains 50 ~ 1000m, can keep high-axiality within the scope of Controllable Error with axis of bore.
Advantage of the present utility model and beneficial effect are:
1, adopt laser alignment device, the preliminary pointing correction of firearms can be realized without the need to shooting.
2, through the testing authentication of reality, native system jumps angle and bias current test error is respectively 20 " and 0.05mil, measuring accuracy improves about 33% and 50% respectively.

Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of high accuracy ballistic deflection system for measuring quantity, comprises as lower device:
Shooting platform 5, has height, two, left and right free degree regulatory function, and gun barrel 4 is fixed on shooting platform 5, can the various firearms of fixed clamp.
Laser alignment device, preferably laser school rifle device, is arranged on gun barrel 4, for front inserting or shell type comprise 5.8mm, 7.62mm, 12.7mm, 14.5mm tetra-kinds of bores, laser range contains 50 ~ 1000m, can keep high-axiality within the scope of Controllable Error with axis of bore.
Directive demarcates target 3, is arranged between shooting platform 5 and departure receiving target 1, which is provided with coordinate grid, can ensure that bullet passes through rear substantially without kinetic energy loss.
Departure receiving target 1, is provided with coordinate grid, has excellent diffuse reflection performance, can ensure that long-haul reliable receives laser beam 2, simultaneously effectively dispersion laser hot spot brightness, and protection observer uses eye safety.
The concrete measuring process of the utility model comprises jumps angular measurement and bias current is measured, and its concrete measuring process is:
As shown in Figure 4, the test method at angle is jumped in test, can be divided into following step:
1) gun barrel 4 is fixed on shooting platform 5, arranges departure receiving target 1 in muzzle front X distance;
2) level meter is used to mark muzzle horizontal line on departure receiving target 1;
3) use laser school rifle device on departure receiving target 1, mark muzzle and point to some E;
4) shooter shoots one group of bullet, and departure receiving target 1 target surface is determined the center of impact A of this group bullet;
5) do the horizontal vertical line of muzzle from A point, E point, determine that to the horizontal distance of muzzle, is respectively at these 2
with
6) each for gained data input computer software can be jumped angle final calculation result.
Wherein:
for trajectory height mean value on sight line, unit is m;
V
cpfor the average speed of bullet between muzzle to target, unit is m/s;
X is range, and unit is m;
for axis of bore and target surface intersection point E are to the distance of horizontal plain, unit is m;
T is bullet tangent to the trajectory and target surface intersection point when going out muzzle;
E is axis of bore and target surface intersection point;
A is center of impact;
F is muzzle horizontal line and target surface intersection point.
As shown in Figure 5, the test method of test bias current, can be divided into following step:
1) gun barrel 4 is fixed on shooting platform 5, at distance muzzle front h
1place places directive and demarcates target 3 apart from l
1, at distance muzzle front h
2departure receiving target 1 is placed apart from l by place
