Optical calibrator

Abstract

The invention discloses an optical calibrator. The technical scheme is that: the optical calibrator comprises a protective cover; the front and rear ends of the protective cover are provided with a front cover and a rear cover; the front cover is a cylinder; the front end of the front cover is provided with a conical surface positioning sleeve; the rear end of the front cover is provided with light-transmitting glass; the protective cover is provided with a view window; the rear end of the front cover is fixedly provided with a reflecting mirror fixing seat; a semi-passing semi-reflecting mirror is embedded into the reflecting mirror fixing seat and corresponds to the view window; an included angle of 45 degrees is formed between the semi-passing semi-reflecting mirror and the conical surface positioning sleeve; a light passing hole is formed in the middle of the semi-passing semi-reflecting mirror; a laser is arranged in the protective cover; and the emergent light of the laser can pass through the light passing hole. The optical calibrator has the advantages of compact and reasonable structure, high positioning accuracy, long service life and novel appearance design.

Description

technical field [0001] The invention relates to an antiaircraft gun aiming calibration device, in particular to an optical calibrator. Background technique [0002] The anti-aircraft gun system requires radar and anti-aircraft gun anti-target calibration before daily combat readiness checks and combat missions. In anti-target calibration, it is generally necessary to install a reticle on the muzzle of the anti-aircraft gun, then unbolt the breech, and place a shell case with the primer removed and a reflector device made by the army in an appropriate position. This kind of self-made mirror device is usually made by carving a groove on a long wooden strip, and then clamping an ordinary small flat mirror on the groove. During the day, the reflector device reflects natural light through the muzzle reticle to form a reflective target. And at night, because the light is relatively weak, it is generally necessary to use a flashlight to irradiate the reflector device to form a re...

AI Technical Summary

Problems solved by technology

[0004] 1. Because the reflector device is made by the soldiers themselves, the workmanship is generally rough; the size and shape of the device are different, which does not meet the requirements of the regularization and standardized construction of the army

[0005] 2. The shape of each reflector device is different, and the position of placing it in the gun bore is different, so the anti-target information such as the azimuth angle and high-low angle of the artillery obtained by the radar is not necessarily accurate, which affects the accuracy of the anti-aircraft gun shooting

[0006] 3. Natural light sources and flashlight light sources have relatively large scattering and are easily disturbed by the environment. Therefore, the anti-target performance is relatively poor, resulting in the anti-target time of each anti-aircraft gun being as long as about 3 minutes, which is not conducive to the emergency combat response of the troops.

[0007] 4. Before each combat mission, the troops have to purchase flashlights and batteries. These non-standard equipment are not easy to manage in a unified way, and they are often lost. Moreover, some soldiers randomly discard batteries, which may cause environmental problems.

[0008] 5. The self-made reflector device requires soldiers (usually four gunners) to repeatedly extend their hands into the gun bore to adjust the position. At this time, if the operator on the gun makes a wrong operation (for example, if the firing skid is not placed), the firing lock may occur, resulting in a safety accident. occur

[0009] 6. The self-made device may be overturned in the gun bore when the gunner operates the anti-aircraft gun for anti-target calibration, and it is difficult to remove

If the plane mirror breaks after being overturned accidentally, the antiaircraft gun must be disassembled and cleaned before it can be put into combat

[0010] 7. Homebrews lack error-proofing and may be left in the barrel

If the gunner fires, it will damage the firing pin and other devices of the anti-aircraft gun, which will affect the combat use of the anti-aircraft gun
