Description

Technical Field

[0001] The utility model belongs to the technical field of simulated gun barrels, and in particular relates to a device for simulating the pointing of a gun barrel. Background Art

[0002] Artillery is the main combat equipment of the army, and the barrel is the core component of the artillery. When the artillery is fired, the barrel is not only subjected to the impact and chemical action of the high-temperature and high-pressure gunpowder combustion gas, but also to the friction of the high-speed moving projectile. As a result, there are as many as a dozen defects. If the defects of the artillery barrel cannot be judged and handled in a timely and accurate manner, it may have a major impact on the safe use of the artillery. In order to ensure shooting safety and shooting accuracy, it is necessary to regularly check the state of the artillery barrel to determine the quality level of the artillery barrel.

[0003] The axis of the launch tube of the launch device and the optical axis of the optoelectronic device are not completely parallel. The existing calibration method generally uses the optoelectronic detection device to aim the launch device, but does not take into account the error between the optoelectronic detection device and the barrel axis itself, which affects the judgment of the quality grade of the artillery barrel. For this reason, we propose a device for simulating the pointing of the artillery barrel. Utility Model Content
