Description

Technical Field

[0001] This invention relates to the field of calibration technology, and more specifically to a rapid target calibration system. Background Technology

[0002] The greatest advantage of armed helicopters is their wide range of operations and high maneuverability, and they are not heavily dependent on fixed airfields. Therefore, they are widely used in the military field. In order to ensure the combat mobility of armed helicopters, it is necessary to use a target calibration device to calibrate them.

[0003] Aircraft target calibration equipment is a relatively important support equipment. It is a special equipment used for military aircraft target calibration operations. It is used to calibrate the photoelectric and mechanical axes of aircraft weapon systems and other related airborne equipment relative to the reference axis, and to perform tasks such as verifying the coordination relationship between these spatial axes, measuring initial deviations, and assisting in deviation correction.

[0004] Target calibration is of great significance to ensuring the firing accuracy of military aircraft weapon systems. Traditional target calibration methods are complicated to operate, requiring 6-9 people to spend more than two hours calibrating one aircraft, which is time-consuming and labor-intensive, and greatly reduces the efficiency of military aircraft use. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a rapid target calibration system to solve the problems existing in the background art.

[0006] The present invention provides the following technical solution: a rapid target calibration system, comprising: a laser emitter, a laser receiver, a prism, an information processor, a mounting bracket, and an electronic level; the laser emitter is mounted on the top of the mounting bracket, the laser emitter is a laser emitter with a rotatable laser head and a built-in pentaprism, the prism is mounted on the top of another mounting bracket, the prism is a 90-degree prism, and the laser receiver is fixed to both ends of the device under test by magnetic bases.

[0007] Furthermore, the mounting frame includes a top plate, with three mounting rods fixedly connected to the bottom end of the top plate. A motor is fixedly connected to the inner wall of the top end of each mounting rod, and a mounting block is fixedly connected to the inner wall of the side of each mounting rod. A threaded rod is movably sleeved at the bottom end of each mounting block, and the top end of the threaded rod is fixedly sleeved with the output shaft of the motor. A telescopic rod is threadedly connected to the side of the threaded rod, and the side of the telescopic rod is movably connected to the inner wall of the side of the mounting rod. A roller is fixedly connected to the bottom end of the telescopic rod. A turntable is movably connected to the top end of the top plate via a pin. The laser emitter is mounted on the top end of the turntable, and the prism is mounted on the top end of another turntable.

[0008] Furthermore, a height measuring device is fixedly connected to the top of the top plate, and a level detection device is fixedly connected to the top of the top plate.

[0009] S1. Install the laser emitter on the turntable, move the mounting bracket to a suitable position, and simultaneously start the three motors to drive the threaded rod to rotate. The threaded rod moves along the inner wall of the mounting rod to move the top plate to a suitable height. The level detection device determines whether the top plate is level. The three motors are adjusted to make the top plate level. The height of the laser emitter is measured by the height measuring device to make the laser emitter stand on the baseline. The laser emitted by the laser emitter is the baseline laser line.

[0010] S2. Install the laser receivers at both ends of the device under test using magnetic bases, and install the prism on another turntable, making sure the prism and the laser emitter are at the same height.

[0011] S3. Move the prism to the position to be detected, rotate the built-in pentaprism in the laser emitter so that the laser is emitted at a 90-degree angle to the reference laser line and is emitted onto the prism. The laser is refracted by the prism at a 90-degree angle and emitted out parallel to the reference laser line. The refracted laser shines on the laser receiver to record the laser information and transmits the recorded information to the information processor.

[0012] S4. The information processor automatically calculates the slope of the laser refraction of each device relative to the baseline, and calculates the parallelism between the devices.

[0013] Furthermore, the method for calculating the parallelism of the device.

[0014] .

[0015] Furthermore, the electronic level is placed close to the device being measured to obtain parallelism in both vertical and horizontal directions.

[0016] The technical effects and advantages of this invention are as follows:

[0017] This invention uses three motors to drive the threaded rod to rotate, which in turn moves the telescopic rod along the inner wall of the mounting rod to move the top plate to a suitable height. The horizontal detection device 1 determines whether the top plate is horizontal, and the three motors are adjusted to keep the top plate in a horizontal state. This improves the stability of the equipment and the accuracy of the data, increases work efficiency, and the target calibration work does not have special site requirements, allowing helicopters to be parked freely.

[0018] This invention uses a 90-degree prism to refract the laser emitted by the laser emitter, thereby changing the position of the laser without having to move the laser emitter each time. It is simple to operate, easy to adjust, and helps to improve work efficiency, without requiring extensive technical training for personnel. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The rapid target calibration system involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Reference Figures 1 to 5 This invention provides a rapid target calibration system, comprising: a laser emitter, a laser receiver, a prism, an information processor, a mounting bracket, and an electronic level. The laser emitter is mounted on the top of the mounting bracket and uses a laser emitter head with a rotatable prism. The prism is mounted on the top of another mounting bracket and is a 90-degree prism. The laser receiver is fixed to both ends of the device under test via magnetic bases. The pentaprism is an optical prism with five reflective surfaces, which can deflect incident light by 90 degrees. The incoming light is reflected twice inside the prism, changing its direction by 90 degrees. This not only prevents inversion but also does not change the chirality of the image. Ordinary right-angle prisms, on the other hand, would cause the image to change its chirality.

[0028] The mounting frame includes a top plate 4, with three mounting rods 3 fixedly connected to the bottom of the top plate 4. A motor 8 is fixedly connected to the inner wall of the top of the mounting rod 3, and a mounting block 9 is fixedly connected to the inner wall of the side of the mounting rod 3. A threaded rod 10 is movably sleeved at the bottom of the mounting block 9, and the top of the threaded rod 10 is fixedly sleeved with the output shaft of the motor 8. A telescopic rod 2 is threadedly connected to the side of the threaded rod 10, and the side of the telescopic rod 2 is movably connected to the inner wall of the side of the mounting rod 3. A roller 1 is fixedly connected to the bottom of the telescopic rod 2. A turntable 7 is movably connected to the top of the top plate 4 via a pin. A laser emitter is mounted on the top of the turntable 7, and a prism is mounted on the top of another turntable 7.

[0029] A height measuring device 6 is fixedly connected to the top of the top plate 4, and a level detection device 5 is fixedly connected to the top of the top plate 4.

[0030] A method for operating a rapid target calibration system:

[0031] S1. Install the laser emitter on the turntable 7, move the mounting bracket to a suitable position, and simultaneously start the three motors 8 to drive the threaded rod 10 to rotate. The threaded rod 2 moves along the inner wall of the mounting rod 3 to move the top plate 4 to a suitable height. The level detection device 5 determines whether the top plate 4 is level. The three motors 8 are adjusted to make the top plate 4 level. The height of the laser emitter is measured by the height measuring device 6 to make the laser emitter stand on the reference line. The laser emitted by the laser emitter is the reference laser line.

[0032] S2. Install the laser receivers at both ends of the device under test via magnetic bases, and install the prism on another turntable 7, making the prism and the laser emitter at the same height.

[0033] S3. Move the prism to the position to be tested, rotate the built-in pentaprism in the laser emitter so that the laser is emitted at a 90-degree angle to the reference laser onto the prism. The laser is refracted by the prism at a 90-degree angle and emitted out parallel to the reference laser line. The refracted laser shines on the laser receiver to record the laser information and transmits the recorded information to the information processor. The laser emitter does not move during the entire test.

[0034] S4. The information processor automatically calculates the slope of the laser refraction of each device relative to the baseline, and calculates the parallelism between the devices.
