Description

A device for measuring the inner diameter of a gun barrel

technical field

The utility model relates to the technical field of weapons, in particular to a device for measuring the inner diameter of a cannon barrel.

Background technique

Artillery is the main combat equipment of the army, and the barrel is the core component of the artillery. When the artillery shoots, the barrel is not only subjected to the impact and chemical action of the high-temperature and high-pressure gunpowder combustion gas, but also the friction of the high-speed moving projectile, resulting in more than a dozen kinds of defects; if the defects of the artillery barrel cannot be judged and dealt with in a timely and accurate manner, phenomena such as shell jamming or chamber explosion may occur, which will have a significant impact on the safe use of the artillery. In order to ensure the shooting safety and shooting accuracy of the artillery, it is necessary to regularly check the state of the inner bore of the artillery barrel to judge the quality level of the artillery barrel.

Since the gun barrel is a slender tubular structure, the internal contour measurement space is narrow and the aspect ratio is large, so it is difficult to measure. Many artillery production units cannot carry out effective measurement, and can only measure one diameter value at a time, which is inconvenient to operate, low in work efficiency, and low in measurement accuracy.
