Problems solved by technology

[0003] 1. The barrel of the artillery is long and narrow, and the ambient brightness is low, making it difficult for human eyes to observe;
[0004] 2. The inner diameter of the barrel is generally relatively small, it is difficult for the measuring instrument to enter, and it is difficult to carry out the measurement work;
The traditional mechanical method has a small diameter measurement range and low precision; electronic and optical sensor measurement requires high installation accuracy, poor shock resistance, and complex structure, which is difficult to meet the measurement requirements of small-caliber artillery

Embodiment 1

[0028] Such as figure 1 As shown, a system for measuring the inner diameter of the gun barrel rifling provided in this embodiment includes a measuring vehicle unit, a laser displacement sensor controller 108, and a control computer 107. The measuring vehicle unit communicates with the laser displacement sensor controller 108 through a probe optical cable 106 connected, the laser displacement sensor controller 108 is connected with the control computer 107;

[0029] The measuring car unit includes a motor unit 101, a measuring car shell 211, a rotating bracket 104, a laser displacement sensor probe 105, a front motor flange 203, and a rear motor flange 214. The left end and the right end of the measuring car shell 11 are respectively provided with the The front motor flange 203, the rear motor flange 214, the front motor flange 203 and the motor unit 101, the rotating bracket 104 is arranged on the front motor flange 203, the rear motor flange 214 and is connected in rotation, ...

Embodiment 2

[0032] Such as Figure 2-4 As shown, in this embodiment, the rotating bracket 104 is connected to the laser displacement sensor probe 105 through a positioning bead structure, and the position of the laser displacement sensor probe 105 can be adjusted by adjusting the positioning bead structure. When measuring gun barrels of different calibers, the fixed position of the laser displacement sensor probe 105 is switched by rotating the positioning bead structure on the bracket 104 according to the size of the measured caliber.

[0033] Wherein, the positioning bead structure can adopt known technology.

[0034] In addition, after the measuring vehicle unit is installed into the barrel of the gun to be tested, under the centering action of the front and rear centering claws, the axis of the overall system is coaxial with the axis of the barrel, and the longitudinal axis of the measuring vehicle is perpendicular to the axis of the barrel. When in use, the front centering claw 202 ...

Abstract

The invention discloses an artillery barrel rifling inner diameter measuring system and method. The system comprises a measuring vehicle unit, a laser displacement sensor controller and a control computer, the measuring vehicle unit is connected with the laser displacement sensor controller through a probe optical cable, and the laser displacement sensor controller is connected with the control computer. The inner diameter of the artillery barrel is converted into the eccentricity of the probe of the laser displacement sensor and the distance measurement value converted from reflected light sensed by the probe, the probe is small in structure, and the problem that the installation size is strictly limited is solved. In addition, the measuring system is more stable. In addition, measurement and calculation data of the diameter of the inner wall of the artillery barrel come from distance parameters measured by a laser displacement sensor probe and are related to the eccentric position of the probe.

Description

technical field [0001] The invention relates to the technical field of inner diameter measurement, in particular to a system and method for measuring the inner diameter of a gun barrel rifling. Background technique [0002] During the shooting process of the artillery, the inner diameter of the barrel will change due to factors such as ablation and wear. The structure and size of the inner bore of the gun is an important basis for judging the life of the barrel and analyzing the shooting accuracy. Therefore, in various artillery, ammunition tests or shooting tests for shooting tables, it is required to measure the inner diameter of the barrel to check whether its size meets the requirements of the technical conditions and as the number of projectiles increases, the inner diameter of the barrel will change. Changes, compared with the general detection of the inner diameter of the pipeline, the detection of the gun barrel mainly has the following special properties: [0003]...
