Description

Technical Field

[0001] The present invention relates to the field of gun barrel axis adjustment devices, and in particular to a device for adjusting the parallelism of dual gun barrel axes and an adjustment method thereof. Background Art

[0002] At present, when calibrating the parallelism of a twin-barreled gun, the traditional gun calibration scope sets up a target plate with a coordinate dimension diagram of the distance position relationship of the gun barrels at a close distance, adjusts the gun carriage to a horizontal state, and inserts the gun calibration scope into the gun barrels to adjust to the corresponding coordinate points. This process needs to be repeated many times. Especially when troops are calibrating in the field, adjustments are more inconvenient due to terrain restrictions.

[0003] In summary, the inventors have proposed a device and method for adjusting the parallelism of dual-barrel axes. Summary of the Invention

[0004] The present invention aims to provide a device and method for calibrating the parallelism of twin-barrel axes, which solves the problem that conventional calibrating scopes, when calibrating the parallelism of twin-barrel guns, require setting up a target plate with a coordinate dimension diagram showing the distance and position relationship of the gun barrels at a close distance, adjusting the gun carriage to a horizontal state, and inserting the calibrating scopes into the gun barrels to align with the corresponding coordinate points, which requires repeated repetition. This is particularly problematic when troops are calibrating in the field due to terrain restrictions. To achieve the above technical objectives, the present invention employs the following technical solutions:

[0005] A device for adjusting the parallelism of the axes of two gun barrels, comprising a main mirror, a secondary mirror, a main reference shaft, a secondary reference shaft and an angle sensor, wherein the main mirror is mounted on the main reference shaft, the secondary mirror is mounted on the secondary reference shaft, and angle sensors are mounted in both the main mirror and the secondary mirror. The device also comprises a beam splitter, a reflector, a slit collimation system and a camera, wherein the reflector and the slit collimation system are mounted in the secondary mirror, the slit collimation system is mounted between the reflector and the angle sensor, and the slit collimation system comprises a lens, a slit reticle and a bulb from left to right, and the beam splitter and the camera are mounted in the main mirror. In the mirror, the camera is installed between the spectrometer and the angle sensor. The lateral center of the reflector, the lateral center line of the secondary mirror, the center line of the secondary reference shaft, the optical axis of the slit bright line emitted by the slit collimation system and the axis of the right barrel are on the same axis. The slit bright line is emitted after being bent 90 degrees through the reflector and coincides with the optical axis of the spectrometer of the main mirror. The lateral optical axis of the spectrometer, the lateral optical axis of the camera, the lateral center line of the main mirror, the center of the main reference shaft and the axis of the left barrel are on the same axis. The main reference shaft is 90° to the receiving optical axis before entering the camera. The camera is connected to the image analysis software signal.

[0006] It is further limited to also include a data receiving device, which is connected to the camera and image analysis software via WIFI. The reference shafts of the primary mirror and the secondary mirror are elastically and precisely fitted into the two barrels at the same time. When the primary mirror and the camera are aimed at the target, the height and horizontal parallelism correlation data of the primary and secondary mirrors are transmitted through wifi, and the angular errors in the height and horizontal directions between the two barrel axes are processed by software, and the data is transmitted to a flat-panel display (or mobile phone), and the angle voice information is displayed and output through the APP, which is clear and understandable. Not only is the accuracy high, but the correction is also convenient and fast. It overcomes the problems of single function and inconvenience of the original optical calibration target mirror or camera calibration target mirror, and the effect is more obvious compared to field use;

[0007] It is further defined that the data receiving device also has a voice broadcast function, which is a function of the software on the display end, and can broadcast the deviation value of the double barrels in the form of voice.

[0008] It is further defined that the slit bright line emitted by the slit collimation system is in a straight line shape and is also in a straight line shape on the target surface of the camera to facilitate alignment and precision measurement;

[0009] It is further defined that the angle sensor is a high-precision gyroscope angle sensor. When the 0° position of the high-precision gyroscope angle sensor is aligned with the horizontal state of the reference rod axis, the reference axes of the primary mirror and the secondary mirror are aligned with the horizontal position.

[0010] It is further defined that the main reference shaft and the secondary reference shaft can be equipped with models of different outer diameters and sizes to match gun barrels of different calibers.

[0011] It is further defined that it also includes a stray light blocking barrel, which is installed on the side of the main mirror close to the secondary mirror, and the axis position of the stray light blocking barrel is on the same horizontal line as the optical axis of the reflector.

[0012] In addition, the adjustment method of this dual-barrel axis parallelism adjustment device has the following specific steps:

[0013] Step S1: Insert the primary mirror into the left gun barrel. With the barrel facing forward, adjust the barrel pitch until the primary mirror's pitch angle is 0 degrees. Rotate the turret 180 degrees so that the barrel faces backward. The pitch angle displayed in the primary mirror is the fore-aft tilt angle of the gun carriage. Then rotate the turret 90 degrees so that the barrel faces left or right. Use the above method to check the left and right tilt angles (i.e., roll angles). This will yield data on the gun carriage's horizontal state.

[0014] Step S2: Rotate the turret to place the gun barrel in front, insert the primary mirror and secondary mirror into the left and right gun barrels in the direction that the primary mirror's beam splitter inlet and the secondary mirror's reflector outlet are aligned, operate the gun barrels until the primary mirror is at the 0-degree pitch position, rotate the primary mirror and secondary mirror along the barrel axis to correct the roll angle, and then operate the gun barrels to make the primary mirror's pitch angle value 0 degrees; the pitch angle value output by the secondary mirror is the difference between the two gun barrels' height angles.

[0015] Step S3: Rotate the turret to place the gun barrel directly in front, operate the elevation and pitch of the gun barrel until the elevation angle of the main mirror is 0°, rotate the main mirror and the secondary mirror to the left and right tilt angle values measured in step 1 (to eliminate the roll angle), make the beam splitter and the reflector face each other, open the slit collimation system, and reflect the slit bright line to the beam splitter through the reflector. The camera target surface receives the slit bright line from the beam splitter, and obtains the offset through artificial intelligence software recognition and processing. The relative error data on the camera target surface is obtained through image solution, and the horizontal angle difference of the parallelism of the right gun barrel and the left gun barrel can be tested.

[0016] The present invention has the following advantages:

[0017] 1. It has the function of calibrating the parallelism between the gun barrel and the aiming system in the field using the traditional optical (camera) calibration scope.

[0018] 2. The parallelism of the two gun barrels can be adjusted in any place without adjusting the vehicle body level;

[0019] 3. The primary and secondary mirrors can be used separately. When the primary mirror is used independently, it functions as a camera-calibrated gun mirror, allowing for alignment and testing of gun aiming and related systems at long-range targets. It can also serve as an independent level to test and adjust the level of the gun barrel. When the secondary mirror is used independently, it can also serve as an independent level to test and adjust the level of the gun barrel.

[0020] 4. The offset of the double barrels can be broadcasted through voice broadcast. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand, the technical solution of the present invention is further described below with reference to the embodiments:

[0024] Example:

[0025] like Figure 1As shown, a device for adjusting the parallelism of the axes of two gun barrels includes a main mirror 1, a secondary mirror 2, a main reference shaft 3, a secondary reference shaft 4 and an angle sensor 5. The angle sensor 5 is a high-precision gyroscope angle sensor. The main mirror 1 is mounted on the main reference shaft 3, the secondary mirror 2 is mounted on the secondary reference shaft 4, and high-precision gyroscope angle sensors are installed in both the main mirror 1 and the secondary mirror 2. The device also includes a spectrometer 6, a reflector 7, a slit collimation system 8 and a camera 9. The reflector 7 and the slit collimation system 8 are mounted in the secondary mirror 2. The slit collimation system 8 is installed in the secondary mirror 2. Between the reflector 7 and the high-precision gyroscope angle sensor, the slit collimation system is composed of a lens 12, a slit graticule 13 and a light bulb 14 from left to right. The spectroscope 6 and the camera 9 are installed in the main mirror 1. The camera 9 is installed between the spectroscope 6 and the high-precision gyroscope angle sensor. The slit bright line emitted by the slit collimation system 8 is in the shape of a "one", and is also in the shape of a "one" on the target surface of the camera 9, so as to align and measure the progress. The lateral center of the reflector 7, the lateral center line of the secondary mirror 2, the center line of the secondary reference shaft 4, the slit bright line emitted by the slit collimation system 8 are in the shape of a "one". The transverse optical axis of the slit bright line is on the same axis as the axis of the right gun barrel 10, and the slit bright line is emitted after passing through the reflector and turned 90 degrees, and coincides with the optical axis of the beam splitter of the main mirror, and the transverse optical axis of the beam splitter 6, the transverse optical axis of the camera 9, the transverse center line of the main mirror 1, the center of the main reference shaft 3 and the axis of the left gun barrel 11 are on the same axis, and the main reference shaft 3 is 90 ° with the receiving optical axis before entering the camera 9, and also includes a stray light blocking barrel 15, which is installed on the side of the main mirror 1 close to the secondary mirror 2, and the axial position of the stray light blocking barrel 15 is opposite to the reflector 7. The emitted optical axes are aligned horizontally. The camera 9 is signal-connected to the image analysis software and includes a data receiving device and voice broadcast software. The data receiving device is connected to the camera and image analysis software via Wi-Fi. The primary and secondary reference shafts 3 and 4 are precisely inserted into the two barrels. When the cameras are aimed at the target, the elevation and horizontal parallelism data of the primary and secondary mirrors is transmitted via Wi-Fi. The software processes the elevation and horizontal angular errors between the two barrel axes and transmits this data to a flat-panel display (or mobile phone). The app displays and outputs the angle information in a clear and transparent voice. This not only provides high accuracy but also makes calibration quick and easy. This overcomes the single and inconvenient functionality of conventional optical calibration scopes or camera calibration scopes, and is more effective than field use. The voice broadcast software is installed on the data receiving device and can announce the deviation values of the dual barrels via voice. The primary and secondary reference shafts can be equipped with models of different outer diameters and sizes to match barrels of different calibers.

[0026] In addition, the adjustment method of this dual-barrel axis parallelism adjustment device has the following specific steps:

[0027] Step S1: Insert the main mirror 1 into the left gun barrel 11. With the barrel facing forward, adjust the barrel pitch until the main mirror's pitch angle is 0 degrees. Rotate the gun turret 180 degrees so that the barrel faces backward. The pitch angle displayed in the main mirror 1 is the fore-aft tilt angle of the gun carriage. Then rotate the gun turret 90 degrees so that the barrel faces left or right. Use the above method to check the left and right tilt angles (i.e., roll angles). This will yield data on the gun carriage's horizontal state.

[0028] Step S2: Rotate the turret to place the gun barrel in front, align the entrance of the beam splitter 6 with the exit of the reflector 7 and insert them into the left and right gun barrels. Operate the gun barrels until the main mirror appears in the pitch position of 0 degrees. Rotate the main mirror 1 and the secondary mirror 2 along the axis of the gun barrel. After correcting the roll angle, operate the gun barrel height and pitch to make the height and pitch angle value of the main mirror 1 0 degrees. The height and pitch angle value output by the secondary mirror 2 is the height and pitch angle difference of the parallelism of the two gun barrels.

[0029] Step S3: Rotate the turret to place the gun barrel in front, operate the elevation gun barrel to the main mirror elevation angle of 0 °, rotate the main mirror and the secondary mirror to the left and right tilt angle values measured in step 1 (to eliminate the roll angle), make the beam splitter 6 relative to the reflector 7, open the slit collimation system 8, and the emitted light passes through the stray light blocking barrel 15 through the reflector 7 and is reflected to the beam splitter 6. The stray light blocking barrel can play a light-shielding effect when the external light is sufficient during the day. The target surface of the camera 9 receives the slit bright line from the beam splitter 6, and obtains the offset through artificial intelligence software recognition processing. By image solution, the relative error data on the camera target surface can be obtained, and the horizontal angle difference of the right gun barrel (the gun barrel rotates along the Z axis) and the left gun barrel parallelism can be tested.

[0030] This invention solves the problem that the traditional gun calibration scope at the current stage, when calibrating the parallelism of a double-barreled gun, is to set up a target plate with a coordinate dimension diagram of the distance position relationship of the gun barrels at a close distance, adjust the gun carriage to a horizontal state, and insert the gun calibration scope into the gun barrels to adjust the corresponding coordinate points, which needs to be repeated many times; especially when the troops are calibrating in the field, due to terrain restrictions, the adjustment is inconvenient. The main and secondary mirrors can be used separately. When the main mirror is used independently, it is a camera gun calibration scope that can be aimed at long-distance targets to adjust and test the parallelism of the gun aiming and related systems. It can also be used as an independent level to test and debug the horizontal state of the gun body. When used independently, the secondary mirror can also be used as an independent level to test and debug the horizontal state of the gun body. At the same time, the offset of the double gun barrels can be broadcasted in the form of voice broadcast, which is a significant improvement compared with the traditional gun calibration scope.

[0031] The above describes in detail the dual-barrel axis parallelism adjustment device and method provided by the present invention. The specific embodiments described are intended only to facilitate understanding of the method and core concepts of the present invention. It should be noted that those skilled in the art will readily appreciate that various improvements and modifications may be made to the present invention without departing from the principles of the present invention, and such improvements and modifications are also protected by the claims of the present invention.
