Description
Technical field
This patent relates to the cold calibration device of firearms, is specially the device that tool taken aim at by a kind of semiconductor laser Launcher Tube Longitudinal Axis line adjustment firearms.
Background technology
Shoot square, premised on sighting device adjustment must be got well, this is that any weapon has noneffective basic fundamental guarantee.Weapons with pipes, comprise all kinds of firearms of substantial amounts, in the entire life cycle used under arms, all need regularly to the relation of its sighting device (comprising various mechanical tool and optical sight) with actual trajectory, carry out the adjustment that checks and rectify a deviation, be commonly called as " school rifle, school big gun ".Due to the traditional work mode of adjustment firearms, both needed consume a large amount of manpowers and ammunition and limit by environment, and need again to carry out frequently at large, therefore inefficiency integrated cost had been high.
" firearms barrel vertical central axis line laser indication device " (being called for short " laser cold school indication device ") of domestic and international existing application of being on active service, namely miniature semiconductor generating laser is utilized to indicate gun barrel longitudinal center axis, simulation initial trajectory line, as the benchmark of all kinds of sights of small arms of adjustment, theoretically, the accurate firearms adjustment of the high efficiency under not projectile condition, very low cost can be realized, be called for short in " the cold school of laser " or " cold school ".Aforesaid way, has the good prospect of alternative traditional adjustment firearms mode.
At present, can be used for the laser instrument of firearms " cold school " operation, be only limitted to miniature semiconductor laser instrument.But in the research and development and practical application operation of " the cold school of laser " device, because all failing to resolve " optical axis " of semiconductor laser in Emission Lasers regulates and controls problem both at home and abroad, the gun barrel longitudinal center axis that existing " the cold calibration device of laser " indicates, comparatively large with actual deviation value, still not there is the practical value of alternative traditional adjustment firearms traditional work mode.Cause social economy to dive to imitate in huge " the cold school of laser ", be still in " empty talk " status of enduring to the fullest extent and denouncing so far at home and abroad.
Although, there is many decades at home and abroad in " the cold calibration device of laser " of adjustment gun-sight aiming point camera, the still leading position of traditional approach in unable replacement adjustment firearms so far.Its reason is the technical barrier causing the former error larger, slowly fails to overcome.
Be on active service at present both at home and abroad " firearms barrel vertical central axis line laser indication device " (being called for short " laser cold school indication device ") applied, the reason that its precision fails to reach application level is so far more.But location structure is unreliable and the uncertain two large problems of laser optical axis, should be the most scabrous basic fundamental obstacle.Because firearms barrel bore is relatively minimum, the concentrated reflection of above-mentioned technical barrier at various rifle with on " laser cold school indication device ", therefore herein will main with school rifle for case, the reason causing above-mentioned two large technical difficulties is described.
Bullet directive is determined by firearms barrel.Laser beam has collimation physical characteristic, but use the extension line (representing initial trajectory) that it indicates firearms barrel longitudinal axis, in this, as all kinds of benchmark taking aim at tool of adjustment, primary technology prerequisite how to ensure the objective extension line correctly representing firearms barrel longitudinal axis of laser beam, like can be referred to as " positioner of laser in firearms barrel and technology ", be called for short " laser positioning technology ".
" positioner of laser in firearms barrel and technology ", functionally can divide into two subsystems or parts: one is to raise the device and technology that control laser beam optical axis points to from device source, is called for short " laser beam directive control technique "; Two is ensure that laser beam optical axis and firearms barrel longitudinal axis keep coaxial or parallel device and technology, is called for short " laser beam machinery location technology ".From present case, all firearms of active service at home and abroad laser cold school indication device, can resolve all far away this two key technical problems, and this is the major technique reason causing large, the inapplicable problem of their deviations.
"firearms barrel longitudinal axis
"be learning concept, can calculate out by measurement, but and invisible, its physical standard measured or demarcate should be the circular inner wall of firearms barrel.Theoretically, the cylinder that firearms barrel is evenly close to again inwall is inserted in all application, and its central longitudinal axis, can be considered to represent
"firearms barrel longitudinal axis
".This is a kind of simple and practical, locate mode of being widely used at home and abroad " the cold calibration device of laser " at present
.the reliability of this locate mode and smart difficulty, first depend on the stability as the firearms barrel inwall of reference body and accuracy, but this prerequisite does not exist in practice.
The principle of firearms barrel inwall accurate dimension instability is: because of the wearing and tearing of bullet high-speed motion and the effect of ablation repeatedly of superhigh temperature extra-high, in firearms barrel all can there is the progressively expansion that trace level is difficult to measure in thorax bore, and often prop up rifle all oneself specific " wearing and tearing individual character ".
Rigidity limit plug, the backstay in " laser instrument preposition structure ", and play in various degree between the gun barrel bore tube wall often propping up rifle, will be produced." the thick stick pole principle " of preposition structure, can amplify this play again, that final formation departs from gun barrel central axis, that degree is different location declination error.Generally speaking, this error can change with the behaviour in service of rifle, there is indeterminacy and be difficult to correct technology speciality.
The nearly all rifle of active service at home and abroad, with " laser cold school indication device ", all adopts rigidity location structure.It constructs usually, in backstay rear end, rigidity limit plug in gun barrel is installed, at backstay front end fixed laser, during application, backstay is inserted gun barrel location, be arranged on by laser instrument outside muzzle, this universal architecture can be referred to as: " laser instrument preposition structure ".Cause the popular main cause of this structure to be that in gun barrel, space is too narrow and small, miniature semiconductor generating laser cannot be arranged.
But this " laser instrument preposition structure " departs from
"firearms barrel longitudinal axis
"position error, generally all larger, main cause has 3 points: the first, rigidity limit plug on the securing lever and almost often prop up rifle gun barrel inwall between, all can leave the different play of degree; The second, on the securing lever, the structure that the play of rearmounted limit plug combines with the Action of Gravity Field of forward laser light device, must produce " effect of thick stick pole " of amplifying deviation; 3rd, the deviation caused based on " laser optical axis is uncertain " problem must be exaggerated (its principle is aftermentioned).Above-mentioned three kinds of structural position errors, generally all have Overlay, the error of cold school operation can be expanded further to the degree being difficult to be tolerated by user again.
The laser beam that application miniature semiconductor laser instrument is launched, indicating firearms barrel longitudinal center axis, as the benchmark of cold school weapons with pipes sighting system, is the Technology Ways that everybody is not difficult to expect.But a maximum difficult problem is, as the platform of Emission Lasers bundle, miniature semiconductor laser instrument has the structure of multilayer complexity, and itself is also not suitable for for being laser beam precise positioning, more without the function of its optical axis of manipulation adjustment.This is determined by the structure of miniature semiconductor laser instrument and operation principle.If be difficult to " cold school " to research and develop tailored version semiconductor laser, just can only be innovated by application technology, dissolve the application difficult problem of existing semiconductor laser in " cold school ".
In " cold school ", apply miniature semiconductor generating laser a difficult problem and Principle Problems comprise:
There is certain angle of divergence when producing laser in the PN junction of micro semiconductor laser device, its horizontal boundary treaty 6 degree of-10 degree left and right; About facing upward boundary treaty 15-40 degree of bowing.This just means and leaves PN junction moment, and laser has the scattering form of certain amplitude, and the operational temperature curve of this scattering form and the PN junction of micro semiconductor laser device, individual character is relevant in batches for micro-structure.This will cause optical axis indeterminacy.
Exist between the PN junction of miniature semiconductor laser instrument with mounting platform (diode body) and adjust a coaxial difficult problem.Although can laser beam have been integrated with optical frames, invested the autonomous directionality that it is good, PN junction produce laser moment disperse form and with platform between coaxial indeterminacy technical barrier dissolve not yet.So we can see that the laser beam drop point form of injection still has irregularity feature.
Due to nonuniformity and the optical axis indeterminacy of laser light scattering, the PN junction of miniature semiconductor laser instrument, exist between mounting platform with transmitter platform and adjust a coaxial difficult problem.
Due to nonuniformity and the optical axis indeterminacy of laser light scattering, PN junction, laser diode, the mounting platform of micro semiconductor laser device, between transmitter platform and weapon barrel adaption system, there is the coaxial difficult problem of multiple tune.
The coaxial difficult problem of multiple tune existed during above-mentioned known micro semiconductor laser device Emission Lasers, in various cold school application, may have the character that progression overlap amplifies deviation, and be difficult to measure, regulate and control and correct.
In sum, before failing to resolve the coaxial difficult problem of the multiple tune of micro semiconductor laser device, directly applied to firearms barrel and indicate longitudinal axis and cold school, problem is forbidden in the school that the laser beam as benchmark certainly leads to error larger.Therefore to the imitated of domestic and international similar cold property of the institution product or improvement, be all difficult to overcome above-mentioned inherent shortcoming.
