Description

Technical Field

[0001] The invention relates to a shape correction device, in particular to an airborne blade-shaped antenna shape correction device and method, belonging to the field of antenna shape correction. Background Art

[0002] The airborne knife-shaped antenna is a component that radiates and receives electromagnetic waves in the communication and navigation system. Its appearance and structural characteristics directly affect the application effect of the system. In the actual process of equipment maintenance and support in the aviation maintenance system, the knife-shaped antenna is one of the protection objects. Due to the long-term use of the component, its appearance and structure will change and not meet the specification requirements of the component. Therefore, it needs to be calibrated during the equipment maintenance process. However, the tooling used at this stage is simple and cannot effectively implement the calibration. There is also a risk of damage to the component. In order to improve the effectiveness and scientificity of the knife-shaped antenna calibration, the maintenance operation efficiency and quality of the component will be improved.

[0003] Chinese utility model patent CN202320896537.5 discloses an airborne knife-shaped antenna, which includes a knife-shaped antenna group, an antenna body, a protective member, an extension component and a positioning component, and can adjust the expansion gain according to the complex environment to improve the signal reception strength of the antenna. The disadvantage is that this method only proposes a new type of airborne knife-shaped antenna, and does not involve a method and device for antenna correction.

[0004] Chinese utility model patent CN202221263997.6 discloses an airborne ultra-short wave broadband knife-shaped antenna, which includes a knife radiator unit, a mounting base plate, a fiberglass outer cover, etc., achieving the purpose of miniaturization and broadband antenna. The disadvantage is that this method only proposes an airborne ultra-short wave broadband knife-shaped antenna, and does not involve a method and device for calibrating the antenna.

[0005] Chinese invention patent CN202211549022.4 discloses a deformed dipole blade antenna, which includes an antenna main structure, a radio frequency connector, a dielectric antenna cover, etc., which improves the horizontal gain of the antenna and increases the range. The disadvantage is that this method only proposes an airborne ultra-short wave broadband blade antenna, and does not involve a method and device for calibrating the antenna.

[0006] Chinese utility model patent CN202021029781.4 discloses a corrosion-resistant knife-shaped antenna structure. By providing a first antenna shell and a second antenna shell on the outer side of the antenna body, the first antenna shell and the second antenna shell can be relatively far away from the antenna body for maintenance, thereby achieving the advantage of convenient maintenance. The disadvantage is that this method only proposes a corrosion-resistant knife-shaped antenna structure, and does not involve a method and device for antenna correction.

[0007] The 33rd volume, 4th issue, pp. 62-64 of "Electronic Mechanical Engineering" published in August 2017 disclosed the proposed finite element model correction of the blade antenna based on sensitivity analysis, which mainly used the modal parameters obtained from the modal test to correct the finite element model of a certain blade antenna. After the correction, the maximum relative error of the modal frequency of the finite element model was reduced to less than 10%, and the modal confidence interval (MAC) was greater than 0.8. The disadvantage is that this method only corrects the finite element model of the blade antenna, and does not involve the method and device for antenna calibration.

[0008] Therefore, the research on knife-shaped antennas is mainly focused on the structural design and model correction of machine-mounted antennas, which provides more services for the design and production of products. However, there is less research on the maintenance of aviation equipment, especially on the calibration devices and methods of knife-shaped antennas. It is necessary to carry out research on the calibration devices and methods of knife-shaped antennas. Summary of the invention

[0052] A method for calibrating an airborne blade-shaped antenna, wherein the method calibrates the blade-shaped antenna using a calibration device, and the method further comprises the following steps:

[0053] Step 1: Level the base 1. According to the indications of the X-axis level 9 and the Y-axis level 8 on the base 1, turn and adjust the foot cup 10 under the base 1 to make the base 1 in a horizontal state.

[0054] Step 2: Select and install the antenna mounting platform 2. According to the installation position of the antenna 7 to be calibrated, select the antenna mounting platform 2 that is used in conjunction with the antenna 7 to be calibrated, and install the antenna mounting platform 2 on the base 1.

[0055] Step three: Install the antenna 7 to be calibrated and fix it on the antenna mounting platform 2; place the antenna 7 to be calibrated on the antenna mounting platform 2, adjust it to the preset calibration position, and then use screws to connect and fix the bottom edge of the antenna 7 to the top of the antenna mounting platform 2.

[0056] Step 4: Selection and assembly of antenna protection connector 3: According to the requirements of the external dimensions of the antenna 7 to be calibrated, the corresponding antenna protection connector 3 is selected and mounted on the outside of the antenna 7 to be calibrated. The antenna 7 to be calibrated only deviates from the center line in appearance, and no major deformation occurs. The matching antenna protection connector 3 can be smoothly mounted on the outside of the antenna 7 to be calibrated, and can clearly show the external contour of the antenna 7 to be calibrated.

[0057] Step 5: Preliminary adjustment of the two-dimensional displacement platform 4. According to the deformation of the shape of the antenna 7 to be calibrated that deviates from the center line, the two-dimensional displacement platform 4 is preliminarily adjusted; first, the horizontal screw 15 is turned to adjust the horizontal threaded slide 14 to a preset horizontal position, and then the vertical screw 12 is turned to adjust the vertical threaded slide 13 to a preset height position; so that the vertical threaded slide 13 is connected to the ear 16 through the connecting rod 5, and the number of subsequent rotations of the horizontal screw 15 and the vertical screw 12 can be reduced accordingly, thereby facilitating the control of the calibration force.

[0058] Step 6: Connect the connecting rod 5, and rotate and install the end of the connecting rod 5 away from the vertical threaded slide 13 through the pin shaft and the ear 16 on the same side thereof.

[0059] Step 7: Rough calibration of the antenna 7 to be calibrated. Turn the horizontal screw 15 to drive the horizontal threaded slide 14 to move in the horizontal direction, generate a horizontal force for calibration, and form a force to deflect the antenna 7 to be calibrated toward the center until the antenna 7 to be calibrated is deflected to the center position. A limiter is configured on the horizontal hand-held ball screw threaded slide module. After rough calibration, the limiter is locked so that the horizontal threaded slide 14 cannot move anymore.

[0060] Step 8: Fine-tune the antenna 7 to be calibrated by twisting the vertical screw 12 to drive the vertical threaded slide 13 to move up or down in the vertical direction, generating a vertical force for calibration, thereby forming a force that causes the antenna 7 to be calibrated to deflect toward the center until the antenna 7 to be calibrated is deflected to the center position; a limiter is configured on the vertical hand-held ball screw threaded slide module, and the limiter is locked after fine-tune.

[0061] Step 9: Keep and lock the limiters in the horizontal and vertical directions, and keep the vertical screw rod 12 and the horizontal screw rod 15 motionless and stationary for 2 hours or more.

[0062] Step 10: Check and calibrate. Remove the pin at the connection between the ear 16 and the connecting rod 5, separate the ear 16 from the connecting rod 5, and check the alignment of the antenna 7 to be calibrated. You can use visual inspection or auxiliary equipment to check. If the test result does not meet the preset requirements, reconnect the ear 16 and the connecting rod 5, and then proceed to steps 8 and 9 in sequence. If it meets the preset requirements, proceed to the next step.

[0063] Step 11: disassemble the antenna 7 to be calibrated, remove the antenna protection connector 3 mounted on the antenna 7 to be calibrated, and then remove the antenna 7 to be calibrated from the antenna mounting platform 2, and the antenna calibration is completed; if the calibration of the next antenna 7 of the same type to be calibrated is to be continued, return to step 3, reinstall the antenna 7 to be calibrated for calibration; if the calibration of the same type of antenna is not to be continued, reset the two-dimensional displacement platform 4.

[0064] Step 12: Reset the two-dimensional displacement platform 4, remove the connecting rod 5 from the vertical threaded slide 13, and then respectively screw the vertical screw rod 12 and the horizontal screw rod 15 to move the vertical threaded slide 13 and the horizontal threaded slide 14 to the preset original position.

[0065] Step 13: Disassemble the antenna mounting platform 2. Disassemble the antenna mounting platform 2 from the base 1. If calibration needs to be performed on different types of antennas 7 to be calibrated, continue to select the corresponding antenna mounting platform 2 for installation, and reinstall the antenna 7 to be calibrated for calibration. If no antenna calibration is to be performed, end the operation.

[0066] Step 14: End, complete the calibration of the antenna 7 to be calibrated, and count and organize the various components of the device.
