Description

Technical Field

[0001] This utility model relates to the field of artillery loading device calibration technology, specifically a laser calibration device suitable for vehicle-mounted artillery loading devices. Background Technology

[0002] A cannon consists of a barrel and a carriage. The barrel comprises the breech, breech, breechblock, and muzzle device. The breech is the main body of the cannon, used to impart initial velocity and flight direction to the projectile. Rifled cannons spin the projectile to maintain its flight stability, while smoothbore cannons generally do not spin the projectile. They are typically made of high-grade nickel-chromium-molybdenum alloy steel. The breech is used to mount the breechblock and connect the barrel to the recoil mechanism. The breechblock is used to lock the breech, fire the projectile, and extract the propellant cartridge after firing. Modern cannons mostly use semi-automatic breechblocks, which are generally wedge-shaped. They open after firing due to the recoil motion of the barrel and close automatically after loading a projectile. Loading and firing are both done manually.

[0003] In existing artillery, the rotation angle of the loading device is controlled by an encoder during shell loading. However, after rotation, the clamping error between the tray axis and the barrel axis cannot be known. Alignment work is required to check whether the tray axis and the barrel axis coincide to ensure that the projectile can be correctly fed into the barrel. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a laser calibration device suitable for vehicle-mounted artillery loading devices, addressing the above-mentioned shortcomings.

[0005] To solve the above technical problems, the present invention adopts the following technical solution:

[0006] A laser calibration device suitable for vehicle-mounted artillery loading equipment includes a shell-carrying tray laser emitter, a barrel locator, a barrel angle sensor, and a shell-carrying tray angle sensor. The shell-carrying tray laser emitter is placed on the shell-carrying tray of the artillery to emit an alignment laser. The barrel locator is inserted into the inside of the artillery barrel to receive the alignment laser emitted by the shell-carrying tray laser emitter. A laser receiving plate is provided inside the barrel locator, and the laser receiving plate is divided into a qualified area and other areas. The barrel angle sensor and the shell-carrying tray angle sensor are used to detect the elevation angle of the artillery barrel and the shell-carrying tray in a vertical plane. Both the barrel angle sensor and the shell-carrying tray angle sensor are electrically connected to the barrel locator via wires. The barrel angle sensor and the shell-carrying tray angle sensor are wirelessly connected to an external display device, which is used to display the detection results of the barrel angle sensor and the shell-carrying tray angle sensor.

[0007] Furthermore, both the bore angle sensor and the ricochet angle sensor are provided with magnetic bases at their bottoms, and mounting plates for fixed connection with the magnetic bases are provided on both the left and right sides of the bore angle sensor and the ricochet angle sensor.

[0008] Furthermore, the laser receiving plate is divided into a planar coordinate system, and the coordinate range of the qualified area can be set.

[0009] Furthermore, both the laser emitter on the ammunition tray and the barrel locator are equipped with batteries.

[0010] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0011] This invention utilizes a laser emitter on the ammunition tray to emit an alignment laser, which is then received by a barrel locator. This allows for direct and precise detection of whether the tray axis and the barrel axis coincide, ensuring that the projectile is correctly fed into the barrel. This solves the problem in existing technologies where the error between the tray axis and the barrel axis cannot be directly determined. The barrel angle sensor and the ammunition tray angle sensor detect the elevation angle of the gun barrel and the ammunition tray in the vertical plane, displaying the results on an external display device. The gun can calculate the angle that the loading device needs to correct based on the detection results, thus adjusting the gun's fire control system. The barrel angle sensor and the ammunition tray angle sensor are equipped with magnetic bases at their bottom for easy and quick installation and removal. Furthermore, these sensors are wirelessly connected to the external display device, simplifying the connection process and improving ease of use.

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0023] like Figure 1-6 As shown, a laser calibration device suitable for vehicle-mounted artillery loading equipment includes a shell-carrying tray laser emitter 1, a gun barrel locator 2, a gun barrel angle sensor 3, and a shell-carrying tray angle sensor 4. The shell-carrying tray laser emitter 1 is placed on the shell-carrying tray of the artillery to emit an alignment laser. The gun barrel locator 2 is inserted into the inside of the gun barrel to receive the alignment laser emitted by the shell-carrying tray laser emitter 1. A laser receiving plate 5 is provided inside the gun barrel locator 2, and the laser receiving plate 5 is divided into a qualified area and other areas. The gun barrel angle sensor 3 and the shell-carrying tray angle sensor 4 are used to detect the elevation angle of the gun barrel and the shell-carrying tray in the vertical plane. The gun barrel angle sensor 3 and the shell-carrying tray angle sensor 4 are electrically connected to the gun barrel locator 2 through wires. The gun barrel angle sensor 3 and the shell-carrying tray angle sensor 4 are wirelessly connected to an external display device, which is used to display the detection results of the gun barrel angle sensor 3 and the shell-carrying tray angle sensor 4.

[0024] In one embodiment, both the bore angle sensor 3 and the scoop angle sensor 4 are provided with magnetic bases 6 at their bottoms, and mounting plates 7 for fixed connection with the magnetic bases 6 are provided on both the left and right sides of the bore angle sensor 3 and the scoop angle sensor 4.

[0025] As one implementation, the laser receiving plate 5 is divided into a planar coordinate system, and the coordinate range of the qualified area can be set.

[0026] In one embodiment, both the missile tray laser emitter 1 and the gun barrel positioner 2 are equipped with batteries.

[0027] In this invention, the laser receiving plate 5 is model JY-MRT, and the barrel angle sensor 3 and the flank angle sensor 4 are both model KINAX N702 high-precision tilt sensors. The origin coordinates of the plane coordinate system can be adjusted through an external display device. The correction angle calculation formula is: Correction angle = Barrel angle sensor detection angle - Flank angle sensor detection angle - Gun barrel self-check angle - Flank self-check angle + Correction angle constant.

[0028] The working process of this utility model is as follows:

[0029] Place the mortar laser emitter 1 on the artillery mortar. Insert the breech positioner 2 into the inside of the artillery breech. Install the breech angle sensor 3 and the mortar angle sensor 4, ensuring they are electrically connected to the breech positioner 2 and wirelessly connected to the external display device. Turn on the mortar laser emitter 1 to emit an alignment laser. The laser receiver plate 5 inside the breech positioner 2 receives the alignment laser emitted by the mortar laser emitter 1. If the laser does not illuminate the qualified area on the laser receiver plate 5, the breech angle sensor 3 and the mortar angle sensor 4 respectively detect the elevation angle of the artillery breech and the mortar in the vertical plane. Transmit the detected elevation angle data to the external display device. The external display device displays the coordinates of the alignment laser received on the laser receiver plate 5 and the angle between the artillery breech and the mortar. The artillery inspector calculates the angle that the loading device needs to correct and inputs the calculated correction angle into the artillery's fire control system to correct the loading angle. The laser is fired again to check if it illuminates the qualified area. If it does, the verification is complete, the loading device angle is correct, and the adjustment is finished. If it does not illuminate the area, the above steps are repeated for further adjustment and verification until the qualified standard is met.
