Description

Technical Field

[0001] This utility model relates to the field of shooting calibration technology, and in particular to a visual multi-purpose gun calibration turntable. Background Technology

[0002] A two-axis rotary table is a precision adjustment instrument widely used in radar antenna testing, gyroscopes, and precision laser guidance. Shooting accuracy requires high adjustment precision and high stability to the external environment, especially horizontal and pitch calibration (leveling), which is crucial for the accuracy of shooting results.

[0003] Existing shooting calibration equipment, such as Chinese patent CN105241301A published on 2016-01-13, also describes a precision shooting calibration device for light weapons. However, in essence, it still involves observing the deviation of the bullet impact point through the sight after firing and then making corrections one by one. This method relies heavily on experience and takes longer to observe and correct.

[0004] Therefore, it is necessary to design a visual multi-purpose gun calibration turntable that allows the camera to identify the bullet impact point after firing and quickly obtain the deviation value by combining a two-axis turntable and an angle measurement device. This is a reliable technical solution to improve firing efficiency and accuracy calibration efficiency. Utility Model Content

Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Example 1 like Figures 1-3As shown, this utility model provides a visual multi-purpose gun-calibrating turntable, including an azimuth turntable 1, an elevation turntable 2, a vision device (not shown, fixed to one side of a target), and a computing device (not shown, mounted on one side of a base). Both the azimuth turntable 1 and the elevation turntable 2 are connected to angle measuring devices. The elevation turntable 2 is connected to the azimuth turntable 1, and the firing device is fixed to the elevation turntable 2. The angle measuring device includes an encoder. Both the vision device and the angle measuring device are communicatively connected to the computing device; the vision device is used to capture images of the actual bullet impact point.

[0021] Specifically, the azimuth turntable 1 rotates horizontally to adjust the azimuth angle of the shooting equipment, and the elevation turntable 2 rotates vertically to adjust the elevation angle. An angle measuring device measures the rotation angles of the azimuth and elevation turntables in real time to assist the user in precisely adjusting the shooting accuracy. The angle measuring device uses a 10,000-line incremental encoder and displays the azimuth and elevation angles in real time via a digital display, powered by DC power. The vision device uses a high-definition camera (8K / 5-50mm focal length, 12MP lens), powered by DC power, and works with DJI wireless image transmission equipment. It can connect to a tablet via a Type-C interface or a display device via an HDMI interface to display images in real time. The vision device is installed on one side of the target to capture real-time images. The deviation of the impact point measured at different locations can be adjusted by adjusting the scale to ensure accuracy. Data is transmitted to the display and computing devices via wired or wireless connections.

[0022] Example 2 It also includes a base 3, on which the mounting side of the azimuth turntable 1 is fixed. It also includes a U-shaped clamping arm 4, which is connected to the rotating side of the azimuth turntable 1. The mounting side of the pitch turntable 2 is fixed to the inner wall of one side of the U-shaped clamping arm 4. A first vertical plate 51 is connected to the rotating side of the pitch turntable 2, and a second vertical plate 53 is rotatably connected to the inner wall of the other side of the U-shaped clamping arm 4. A horizontal plate 52 connects the first vertical plate 51 and the second vertical plate 53.

[0023] Specifically, the base 3 is made of stainless steel or galvanized steel, has a large weight, and is equipped with lifting holes to effectively resist the impact force on the two-axis turntable and maintain structural stability. In this utility model, the azimuth turntable 1 and the pitch turntable 2 are the same model turntables fixed in different postures. The azimuth turntable 1 is horizontally fixed on the base 3 and rotates horizontally, while the pitch turntable 2 is vertically fixed to the inner wall of one side of the U-shaped clamping arm 4 and rotates vertically. That is, the pitch turntable 2 is fixedly connected to the azimuth turntable 1 through the U-shaped clamping arm 4 to form a two-axis turntable. Its azimuth angle is ±90° rotation with an accuracy of ≤0.05°; its pitch angle is ±15° rotation with an accuracy of ≤0.05°. By adding a reducer and a manual locking device, precise adjustment and position locking can be achieved.

[0024] The first vertical plate 51, the horizontal plate 52, and the second vertical plate 53 form a U-shaped platform. The pitch turntable 2 drives the first vertical plate 51 to rotate, which in turn drives the horizontal plate 52 and the second vertical plate 53 to pitch and rotate synchronously.

[0025] Example 3 It also includes a clamp 6, which is connected to the horizontal plate 52, and the firing equipment is fixed to the clamp 6. The clamp 6 includes an L-shaped support leg 61 and an I-shaped clamp 62. The I-shaped clamp 62 is connected to the top of the horizontal plate 52 through the L-shaped support leg 61. The bottom of the L-shaped support leg 61 is connected to the horizontal plate through a waist hole. One end of the I-shaped clamp 62 is provided with a notch 63 for placing the aiming device of the firing equipment, and the lower side of the I-shaped clamp is provided with an array of grooves for fitting the guide rail of the firing equipment.

[0026] Specifically, the clamp 6 of this utility model can be precisely customized according to the size of the equipment, firmly fixing the shooting equipment to the elevation axis crossbeam. The I-shaped clamp is pressed onto the cross plate by L-shaped legs 61. The shooting equipment (gun) is pressed between the I-shaped clamp 62 and the cross plate 52. The array of grooves on the lower side of the I-shaped clamp 62 is embedded into the guide rail on the barrel to improve stability. The notch 63 allows the sight to be mounted on the gun and placed in it for a better fit, and allows for adjustment of the sight. The bottom of the L-shaped leg 61 is bolted to the outside of the groove on the cross plate 52, and the top is bolted to the I-shaped clamp 62. The I-shaped clamp 62 is supported and fixed above the cross plate 52 by four L-shaped legs 61. The L-shaped legs 61 on both sides can be moved inward or outward through the waist hole to accommodate wider or narrower barrels.

[0027] Example 4 The system calculates the correction angle required for the firing device to hit the bullseye and adjusts the aiming device accordingly. It also includes a display device, with a vision device communicating with the display device to show images in real time.

[0028] Specifically, this utility model completes the adjustment task through the following steps: (1) System Initialization: After the equipment is installed and fixed, the system is first initialized to ensure that each module is running normally: First, the system self-check is performed to ensure that the hardware such as the vision device (HD camera), azimuth turntable 1, pitch turntable 2, and power supply are working normally, and at the same time, the angle deviation when the last task was not completed is cleared to zero. The vision device (HD camera) is used to obtain real-time images of the impact point. The camera can be installed vertically and rotates synchronously with the pitch axis to ensure that the captured image is facing the impact point to reduce perspective error.

[0029] (2) Two-axis turntable control: Adjust the positions of the azimuth angle and elevation angle according to the shooting target (bullseye). Observe the change of the angle value in real time through the display device connected to the computing device, and manually lock the position when the set angle is reached.

[0030] (3) Shooting and observation: Lock the two-axis turntable and issue a shooting command at the same time; after the command is executed, observe the result through a visual device (high-definition camera).

[0031] (4) Analysis and optimization: Use the visual device (high-definition camera) to collect the image of the shooting impact point, and the computing device (computer) calculates its deviation position relative to the bullseye by reading the value through the encoder. The computing device analyzes the offset of the impact point and calculates the tilt direction and amplitude of the shooting device. Then the offset is corrected by adjusting the sight (in this process, the sight can be adjusted after the gun is fixed, or the handwheels of the azimuth turntable and the elevation turntable can be manually controlled after the sight is fixed, both of which actually achieve calibration by adjusting the relative angle between the gun and the sight). Calculated based on a distance of 100m and a downward deviation of 0.01° between the shooting impact point and the bullseye, the height that should be adjusted for the gun to deflect upward / the sight to deflect downward is 100×tan(0.01°)≈0.01745329252m.

[0032] The visualized multi-purpose gun calibration turntable of the present utility model is based on the combination of camera visual device + manual two-axis turntable motion control, which integrates vision and mechanical leveling technologies. It is used to adjust the azimuth and elevation angles during bullet shooting, and can observe the shooting accuracy in real time, realizing precise leveling in shooting tests. This system uses a camera as a visual device to observe the position of the impact point of the shooting result, does not calculate the relative tilt angle, but directly uses the precision digital display encoder matched with the two-axis turntable (azimuth + elevation) for position reading. After the computing device calculates the correction data required to shoot to the bullseye, the scope of the shooting device is adjusted, and then the angle position is continuously detected and corrected through feedback adjustment to ensure that the error is controlled within the allowable range. When the error meets the set threshold, the turntable is locked, the leveling process is completed, the shooting accuracy is ensured, and precise adjustment of the equipment is realized. The process of the present utility model has high repeatability, can reduce manual operations, improve shooting efficiency, the system is stable and reliable, and can adapt to complex field environments (temperature, humidity, etc.). It can not only improve measurement efficiency and reduce human errors, but also be extended to more similar equipment leveling scenarios, with good application prospects. It can realize precise leveling with an error of ≤0.05°, the whole process is visualized, suitable for indoor or complex field environments, has scalability, and can be used for other horizontal adjustment tasks.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
