Description

Technical Field

[0001] This utility model relates to the field of projectile testing technology, and in particular to a comprehensive projectile testing device. Background Technology

[0002] A comprehensive projectile testing system is designed to perform thorough and efficient testing of projectiles to ensure their performance and safety. Such a system typically comprises multiple modules and systems to enable multifaceted testing of the projectile.

[0003] In existing technologies, when testing projectiles, the testing device needs to place the projectile on the testing device by hoisting it. However, due to the large size of the projectile, it is not easy to adjust the hoisting position when the projectile is hoisted onto the testing device. This may cause the projectile's position on the testing device to shift, which is not conducive to accurate positioning of the projectile. In subsequent comprehensive testing of the projectile, this may lead to large errors in the test data of the projectile, affecting the test results. Utility Model Content

[0027] The coarse adjustment component includes a movable plate 202 located at the center of the base frame 100. A sliding frame 209 is slidably mounted on the front side of the movable plate 202. A push hydraulic cylinder 208 is provided between the sliding frame 209 and the movable plate 202. Two symmetrical front positioning rollers 211 are rotatably mounted on the upper end of the sliding frame 209. A rotary motor 212 is provided on the rear side of the sliding frame 209. A transmission gear 210 is fixed at the output end of the rotary motor 212 and the rotating end of the front positioning roller 211. Multiple transmission gears 210 mesh with each other. Placement frames 207 are provided on both the front and rear sides of the movable plate 202. Two symmetrical support rollers 206 are rotatably mounted on the upper end of each placement frame 207. An adjustment component for fine-tuning the tilt height of the rear end of the projectile is provided on the rear side of the movable plate 202.

[0028] The adjustment assembly includes a fixed frame 214 located on the rear side of the movable plate 202. A lifting cylinder 213 is provided between the fixed frame 214 and the movable plate 202. Two symmetrical rear positioning rollers 215 are rotatably mounted on the upper end of the fixed frame 214.

[0029] The fine-tuning component includes a fixed plate 201 located below the movable plate 202. The fixed plate 201 is slidably connected to the base frame 100. Multiple limiting rollers 205 are rotatably mounted on both the front and rear sides of the fixed plate 201. Arc-shaped plates 204 are fixed at both ends of the movable plate 202 near the limiting rollers 205. The arc-shaped plates 204 slide with the limiting rollers 205. A servo lifting hydraulic cylinder 203 is provided between the movable plate 202 and the fixed plate 201. A left-right lateral adjustment system 216 is provided between the fixed plate 201 and the base frame 100. The rotation direction and placement position of the projectile are initially adjusted by the combined action of the pushing hydraulic cylinder 208 and the rotary motor 212 in the coarse-tuning component. Then, the horizontal height of both ends of the projectile is adjusted by the adjustment component to keep both ends of the projectile coaxial. Finally, the circumferential angle of the projectile is adjusted by the fine-tuning component, thereby improving the accuracy of the projectile detection position and ensuring the accuracy of the projectile detection data.

[0030] In this embodiment: the detection mechanism includes a coaxiality detection system 301 located on the front side of the base frame 100, a verticality detection system 303 located on the rear side of the base frame 100, a seam step difference detection system 302 located between the verticality detection system 303 and the coaxiality detection system 301, and a horizontal adjustment system 304 located on the front side of the fixing plate 201.

[0031] Working principle: First, the projectile is placed between two front positioning rollers 211 and two rear positioning rollers 215 by hoisting. Then, the two support rollers 206 on the front and rear placement frames 207 support the front and rear ends of the projectile. After the projectile is placed in the middle of the equipment, the left and right lateral adjustment system 216 is used to adjust the X-axis distance of the projectile to the predetermined position to complete the X-axis alignment. Then, the push hydraulic cylinder 208 is driven to move the sliding frame 209 in the Y-axis to complete the Y-axis alignment. Finally, the horizontal adjustment system 304 is used to adjust the height to complete the Z-axis alignment.

[0032] Then, drive the rotary motor 212, and use multiple transmission gears 210 to simultaneously drive the two front positioning rollers 211 to rotate, causing the projectile to rotate slightly and fine-tune the rotation position of the projectile. Then, start the lifting cylinder 213 to drive the fixed frame 214 to move up and down, and drive the two rear positioning rollers 215 to move up and down, fine-tune the horizontal height of the projectile. Finally, drive the servo lifting hydraulic cylinder 203 to drive the movable plate 202 to rotate slightly on the fixed plate 201, and fine-tune the circumferential angle of the projectile. After the final adjustment is completed, establish a reference coordinate system.

[0033] Then, the coaxiality detection system 301 is moved to the front end of the projectile. By analyzing and comparing it with the product body coordinate system detected in the previous step, the coaxiality of the front compartment is obtained. The movement continues, and then the coaxiality detection system 301 moves to the canard measurement point. It is then compared with the product body reference coordinate system to obtain the installation angle and reverse angle measurement value. Then, the verticality detection system 303 is moved to the detection surface of the projectile. It is compared with the product body reference surface to obtain the end face verticality. Then, the gap step difference detection system 302 is activated to detect the gap width and height difference between the two shells of the projectile to obtain the gap width and height difference between the two shells of the projectile. Finally, the verticality detection system 303 is used to detect the length of the projectile to obtain the total length of the projectile, completing the comprehensive inspection of the projectile.
