And without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0041] Please refer to Figures 1-4 , the present invention provides a calibration tooling and a calibration method for a weathervane - type sideslip angle sensor, aiming to solve the problems that the calibration of the existing weathervane - type sideslip angle sensor may be complex in operation, low in calibration accuracy, and lack of special calibration tooling.

[0042] Specifically, please refer to Figure 1 which is a perspective view of a calibration tooling for a weathervane - type sideslip angle sensor provided by an embodiment of the present invention. The calibration tooling for the weathervane - type sideslip angle sensor includes: an angle dividing plate 10 and a connecting rod 20. Through the design of the angle dividing plate 10 and the connecting rod 20, an operator can conveniently perform angle adjustment and sensor calibration operations. Compared with traditional calibration methods or complex tooling, this structure can reduce the operation difficulty and complexity during the calibration process, improve the calibration efficiency, and save time and labor costs.

[0043] Specifically, the angle dividing plate 10 includes a fixed plate 11 and a rotating plate 12 movably connected to the fixed plate 11. By setting the angle dividing plate 10 to be composed of the fixed plate 11 and the rotating plate 12, and the rotating plate 12 being movably connected to the fixed plate 11, the rotating plate 12 can rotate flexibly relative to the fixed plate 11, providing a basis for angle adjustment during the calibration process. By rotating the rotating plate 12, different angle values can be accurately set, thereby simulating the conditions of the weathervane - type sideslip angle sensor 40 under different sideslip angle states.

[0044] Further, the connecting rod 20 includes a connecting plate 21 and a connecting rod 22 horizontally extending from one side of the connecting plate 21. The connecting plate 21 is fixedly connected to the rotating disk 12. The connecting rod 22 is parallel to the cross bar 41 of the vane - type sideslip angle sensor 40. A fixing portion 221 is provided at the end of the connecting rod 22, and the fixing portion 221 is fixedly connected to the vane 42 of the vane - type sideslip angle sensor 40. The connecting rod 20 includes the connecting plate 21 and the connecting rod 22. The fixed connection between the connecting plate 21 and the rotating disk 12 ensures that the connecting rod 20 can move synchronously with the rotation of the rotating disk 12. The connecting rod 22 is parallel to the cross bar 41 of the vane - type sideslip angle sensor 40, and a fixing portion 221 is provided at the end. This parallel arrangement ensures that during the rotation process, the direction of force transmission is geometrically similar to the direction of aerodynamic force received by the sensor during normal operation. The fixing portion 221 is fixedly connected to the vane 42 of the sensor. When the rotating disk 12 rotates, the connecting rod 20 drives the vane 42 to rotate through the fixing portion 221, realizing an analog change in the angle of the sensor. The calibration tool for the vane - type sideslip angle sensor can accurately control and change the angle of the vane 42 of the vane - type sideslip angle sensor 40 through the coordinated work of the angle dividing disk 10 and the connecting rod 20 for calibration.

[0045] The calibration tool for the vane - type sideslip angle sensor provided by the present invention accurately adjusts the angle through the angle dividing disk 10, and accurately transmits the angle change to the sensor vane 42 through the connecting rod 20, enabling the calibration process to achieve high - precision angle simulation. This helps to improve the calibration accuracy of the vane - type sideslip angle sensor 40, reduce measurement errors, ensure that the sensor can accurately measure the sideslip angle during actual use, and provide reliable flight attitude data for related equipment such as aircraft. The parallelism between the connecting rod 20 and the sensor cross bar 41 and the fixed connection of the fixing portion 221 to the vane 42 make the operation on the sensor vane 42 during the calibration process more similar to the action mode of aerodynamic force on the vane 42 during actual flight, better reflecting the performance of the sensor in the actual working environment and further improving the effectiveness of calibration.

[0046] As a further improvement of the present invention, the fixing part 221 includes a fixing member 2211 perpendicular to the connecting rod 22. The lower end surface of the fixing member 2211 is lower than the upper end surface of the blade 42. A magnetic member 2212 is provided at the bottom end of the fixing member 2211, and the magnetic member 2212 is detachably connected to the fixing member 2211. By setting the fixing member 2211 of the fixing part 221 perpendicular to the connecting rod 22, this vertical structure design enables the fixing member 2211 to stably interact with the blade 42 of the vane-type sideslip angle sensor 40. When the tooling cooperates with the sensor, the vertical fixing member 2211 contacts the blade 42 at an appropriate angle, ensuring the effective transmission of force during the angle adjustment process. By setting the lower end surface of the fixing member 2211 lower than the upper end surface of the blade 42, it is ensured that the fixing member 2211 has sufficient coverage and contact area with the blade 42. During the operation, force can be better applied to the blade 42 to drive the blade 42 to rotate as the connecting rod 20 moves, and a stable connection can be maintained at different angles, ensuring a stable connection between the tooling and the blade 42. During the entire calibration process, even when the angle indexing plate 10 rotates and the connecting rod 20 drives the blade 42 to move, the blade 42 can be effectively prevented from loosening or displacing relative to the tooling, ensuring the accuracy of the calibration operation. By providing a magnetic member 2212 at the bottom end of the fixing member 2211, and the magnetic member 2212 is detachably connected to the fixing member 2211, the magnetic member 2212 uses the magnetic principle to generate an adsorption effect with the blade 42, realizing the fixed connection between the fixing part 221 and the blade 42. The detachable connection method facilitates the replacement of the magnetic member 2212 as needed, achieving the purpose of connecting the blade 42 without damage. Compared with the traditional mechanical connection method, it will not cause damage to the blade 42 and protects the integrity of the sensor. At the same time, the magnetic adsorption method makes the installation and disassembly very convenient. The operator can quickly connect or separate the tooling from the sensor blade 42, improving the efficiency of the calibration work. At the same time, the detachable connection between the magnetic member 2212 and the fixing member 2211 increases the flexibility of the tooling. According to the material, shape and other characteristics of the blade 42 of different types of vane-type sideslip angle sensors 40, a suitable magnetic member 2212 can be selected or other connection methods can be replaced, enabling the tooling to be applicable to the calibration of a variety of different specifications of sensors, expanding the applicable range of the tooling, and also facilitating adjustments or replacements of other types of connection methods in some special cases, such as when the blade 42 material is not suitable for magnetic adsorption, etc.

[0047] As a further improvement of the present invention, please refer to Figures 2-3, the rotating disk 12 includes a first rotating disk 121 and a second rotating disk 122. The first rotating disk 121 includes a first rotating ring 1211 and a first rotating cylinder 1212 connected to the inner wall of the first rotating ring 1211. The second rotating disk 122 includes a second rotating ring 1221 and a second rotating cylinder 1222 connected to the inner wall of the second rotating ring 1221. The second rotating cylinder 1222 is sleeved inside the first rotating cylinder 1212. The lower end surfaces of the first rotating cylinder 1212, the second rotating cylinder 1222, and the fixed disk 11 are in the same plane. By setting the rotating disk 12 to be composed of the first rotating disk 121 and the second rotating disk 122, the first rotating ring 1211 and the first rotating cylinder 1212 of the first rotating disk 121 are connected, the second rotating ring 1221 and the second rotating cylinder 1222 of the second rotating disk 122 are connected, and the second rotating cylinder 1222 is sleeved inside the first rotating cylinder 1212. The nested double-rotating-cylinder design of the second rotating cylinder 1222 and the first rotating cylinder 1212 forms a double-layer rotating structure. By operating the first rotating disk 121 and the second rotating disk 122 respectively, multi-stage adjustment of the angle of the angle indexing disk 10 can be achieved, which helps to more accurately simulate the sideslip angle of the vane-type sideslip angle sensor 40 under different working conditions, improve the calibration accuracy, and make the calibration of the sensor more in line with various complex situations that may be encountered in actual flight. By setting the lower end surfaces of the first rotating cylinder 1212, the second rotating cylinder 1222, and the fixed disk 11 to be in the same plane, the stability and integrity of the entire rotating disk 12 when cooperating with other components are ensured, unnecessary shaking and vibration are reduced, the measurement error of the angle deviation caused by shaking is prevented, and the reliability of the calibration result is guaranteed. At the same time, the design of the lower end surfaces of the first rotating cylinder 1212, the second rotating cylinder 1222, and the fixed disk 11 being coplanar can make the force distribution more uniform, avoid the influence of torque or unbalanced force generated by the height difference on the normal rotation and calibration accuracy of the angle indexing disk 10. The structural design of the double rotating disk 12 better disperses the friction and stress during the rotation process, reduces the local wear of the components, improves the durability of the rotating disk 12, extends the service life of the tooling, and reduces the use cost.

[0048] As a further improvement of the present invention, a first rotating member 12211 is provided on the outer wall of the second rotating ring 1221. A locking hole 12112 is formed on the outer wall of the first rotating ring 1211, and a locking member 12113 is disposed in the locking hole 12112. The locking member 12113 abuts against the second rotating cylinder 1222. By providing the first rotating member 12211 on the outer wall of the second rotating ring 1221, the operation of rotating the second rotating disk 122 can be realized. When an operator applies an external force to the first rotating member 12211, the force is transmitted to the second rotating cylinder 1222 through the second rotating ring 1221, thereby driving the second rotating disk 122 to rotate around its axis, causing an angular difference between the second rotating disk 122 and the fixed disk 11, realizing rough adjustment of the angle, making the rotation operation of the second rotating disk 122 more convenient and controllable. By forming the locking hole 12112 on the outer wall of the first rotating ring 1211 and placing the locking member 12113 to abut against the second rotating cylinder 1222, when it is necessary to fix at a corresponding angle, the locking member 12113 is rotated to move it in the locking hole 12112 and tightly abut against the second rotating cylinder 1222. By increasing the frictional force or directly mechanical blocking effect, the rotation of the second rotating cylinder 1222 is restricted, and further the second rotating disk 122 is fixed at the required angular position, ensuring the stability of the angle, preventing angle changes caused by external interference, such as slight vibration, etc., enabling the sensor to obtain accurate and reliable data during angle measurement calibration, and ensuring the quality of the calibration result.

[0049] As a further improvement of the present invention, a second rotating member 12111 is provided on the outer wall of the first rotating ring 1211. A rotating support 111 is provided on the fixed disk 11 corresponding to the second rotating member 12111. An adjustment hole 1111 is provided on the rotating support 111 facing the second rotating member 12111. The second rotating member 12111 slides in the adjustment hole 1111 along the opening direction. By providing the second rotating member 12111 on the outer wall of the first rotating ring 1211 to cooperate with the rotating support 111 on the fixed disk 11, the rotating support 111 provides a support and a guiding structure for the movement of the second rotating member 12111, so that the rotation of the first rotating ring 1211 is converted into the horizontal movement of the second rotating member 12111 in the direction of the adjustment hole 1111. Through the sliding of the second rotating member 12111 in the adjustment hole 1111 of the rotating support 111, the stability of the first rotating ring 1211 during rotation is ensured, the fine adjustment of the angle of the angle indexing disk 10 is realized, and a more precise control is provided for the angle adjustment. The sliding of the second rotating member 12111 in the adjustment hole 1111 can achieve small-amplitude and high-precision angle changes, which helps to more accurately adjust the angle of the angle indexing disk 10, and further better simulate the states of the vane-type sideslip angle sensor 40 under various sideslip angle conditions, improving the calibration accuracy. At the same time, the constraint effect of the rotating support 111 and the adjustment hole 1111 on the second rotating member 12111 reduces the unnecessary wear and damage of the components during the movement process, reduces the risk of component failure caused by abnormal force or collision, improves the overall reliability and durability of the calibration tooling, and reduces the maintenance cost and replacement frequency.

[0050] As a further improvement of the present invention, an adjustment shaft 1112 is provided on the rotating support 111. The adjustment shaft 1112 is perpendicular to the second rotating member 12111. The adjustment shaft 1112 includes a first adjustment shaft 11121 and a second adjustment shaft 11122. The first adjustment shaft 11121 and the second adjustment shaft 11122 abut against the end of the second rotating member 12111, and the first adjustment shaft 11121 is connected to an adjustment knob 111211. By providing the adjustment shaft 1112 on the rotating support 111 and making it perpendicular to the second rotating member 12111, the adjustment shaft 1112 can effectively contact and act on the second rotating member 12111 from the side. The first adjustment shaft 11121 and the second adjustment shaft 11122 respectively abut against the end of the second rotating member 12111, forming a constraint and control on the second rotating member 12111 in its axial direction. The first adjustment shaft 11121 is connected to the adjustment knob 111211. When the adjustment knob 111211 is rotated, torque is transmitted to the second rotating member 12111 through the first adjustment shaft 11121. Since the second rotating member 12111 is restricted by the abutment of the first adjustment shaft 11121 and the second adjustment shaft 11122 at the end, it can only move in a predetermined manner under the action of the adjustment shaft 1112, that is, slide along the opening direction in the adjustment hole 1111, thereby realizing precise adjustment of the rotation angle of the first rotating ring 1211. During the calibration process, the operator can accurately control the rotation angle of the first rotating ring 1211 by rotating the adjustment knob 111211 according to the calibration requirements, and then accurately adjust the angle of the entire angle index plate 10, better simulating the working conditions of the vane-type sideslip angle sensor 40 at different sideslip angles, and effectively improving the calibration accuracy.

[0051] As a further improvement of the present invention, it further includes a base 30. The base 30 includes a first mounting plate 31, a second mounting plate 32, and a bottom plate 33 that are arranged in parallel from top to bottom. The first mounting plate 31 is detachably connected to the fixed disk 11, and the second mounting plate 32 is detachably connected to the vane-type sideslip angle sensor 40. By providing that the base 30 is composed of the first mounting plate 31, the second mounting plate 32, and the bottom plate 33 that are arranged in parallel from top to bottom, the multi-layer structure design provides a stable support platform for the entire calibration tooling and the vane-type sideslip angle sensor 40, ensuring uniform force among the first mounting plate 31, the second mounting plate 32, and the bottom plate 33, and being able to effectively bear the weight of the upper components and the forces generated during the operation. The detachable connection between the first mounting plate 31 and the fixed disk 11 enables the angle dividing disk 10 to be conveniently installed on the base 30 and also facilitates disassembly for maintenance or replacement. The detachable connection between the second mounting plate 32 and the vane-type sideslip angle sensor 40 facilitates the installation and disassembly of the sensor, making the combination and separation operations of the sensor and the calibration tooling simple and easy, improving the assembly efficiency. When maintenance, repair, or replacement of the tooling or the sensor is required, it can also be quickly disassembled, reducing the operation difficulty and time cost. At the same time, it is adaptable to fixed disks 11 and vane-type sideslip angle sensors 40 of different models or specifications. Only by replacing the corresponding connecting components or adjusting the connection method can it be used in cooperation with a variety of devices, improving the versatility and application range of the entire calibration tooling.

[0052] As a further improvement of the present invention, a set of struts 34 is provided between the second mounting plate 32 and the bottom plate 33. The struts 34 are detachably connected to the second mounting plate 32, and a set of foot pads 331 is provided at one end of the bottom plate 33 close to the ground. By providing a set of struts 34 between the second mounting plate 32 and the bottom plate 33, the struts 34 are detachably connected to the second mounting plate 32. These struts 34 play a role in supporting the second mounting plate 32. They lift the second mounting plate 32 to a certain height, so that the vane-type sideslip angle sensor 40 is at a suitable working height after installation, facilitating cooperation with other components of the calibration tooling. The detachable connection facilitates the installation, adjustment, and replacement of the struts 34 to adapt to different usage scenarios or equipment requirements. By providing a set of foot pads 331 at one end of the bottom plate 33 close to the ground, the friction between the bottom plate 33 and the ground is increased, preventing the entire tooling from sliding due to external forces during use and ensuring the stability of the tooling. At the same time, the foot pads 331 can buffer the impact force from the ground to a certain extent, protect the internal structure of the tooling, extend the service life of the tooling, and reduce the risk of damage caused by external impacts, thereby reducing the maintenance cost and the replacement frequency of the tooling.

[0053] Please refer to Figure 4, the present invention also provides a calibration method for a wind vane type sideslip angle sensor 40, which is implemented based on the above-mentioned calibration tooling for the wind vane type sideslip angle sensor. The method includes the following steps:

[0054] Fix the angle indexing plate 10 at zero degree, and the magnetic member 2212 fixes the blade 42;

[0055] Calibrate the current angle of the wind vane type sideslip angle sensor 40 to zero degree;

[0056] Specifically, when both the angle indexing plate 10 and the blade 42 are in the initial stable state, calibrate the current angle of the wind vane type sideslip angle sensor 40 and set it to zero degree. Establish the correspondence between the measured angle of the sensor and the angle simulated by the calibration tooling to ensure that the sensor can accurately sense and record the corresponding changes when adjusting the angle subsequently.

[0057] Adjust the angle indexing plate 10 to the first angle;

[0058] The connecting rod 22 drives the blade 42 to rotate by the first angle;

[0059] Specifically, through components such as the first rotating member 12211, the second rotating member 12111 on the rotating disk 12 and the cooperating adjusting shaft 1112, adjusting knob 111211, etc., accurately rotate the angle indexing plate 10 to the required first angle in a predetermined operation manner. When the angle indexing plate 10 rotates to the first angle, since the connecting plate 21 of the connecting rod 20 is fixedly connected to the rotating disk 12 and the connecting rod 22 is also fixedly connected to the blade 42, the connecting rod 22 will move synchronously with the rotation of the rotating disk 12, thereby driving the blade 42 to also rotate to the first angle, ensuring that the rotation angle of the blade 42 is consistent with the adjusted angle of the angle indexing plate 10.

[0060] Calibrate the current angle of the wind vane type sideslip angle sensor 40 to the first angle.

[0061] Specifically, after the blade 42 is driven by the connecting rod 22 to rotate to the first angle, calibrate the current angle of the wind vane type sideslip angle sensor 40 again and set it to the first angle. In this way, the calibration process from the initial zero degree to the first angle is completed, enabling the sensor to accurately identify and measure the corresponding sideslip angle situation at this angle.

[0062] As a further improvement of the present invention, the adjusting the angle indexing plate 10 to the first angle specifically includes:

[0063] Rotate the first rotating member 12211 to adjust the angle indexing plate 10 close to the first angle;

[0064] Specifically, when the angle index plate 10 needs to be adjusted to the first angle, first rotate the first rotating member 12211 provided on the outer wall of the second rotating ring 1221. The rotation of the first rotating member 12211 will drive the second rotating ring 1221 and the second rotating cylinder 1222 connected thereto to rotate, so that the entire rotating disk 12 starts to rotate. Since the first rotating member 12211 can relatively flexibly control the rotation of the rotating disk 12, the operator can perform a preliminary angle adjustment on the angle index plate 10 by carefully operating the first rotating member 12211, making it gradually approach the required first angle. This preliminary adjustment method can quickly bring the angle index plate 10 close to the target angle, laying a foundation for subsequent precise adjustment.

[0065] Rotate the adjustment knob 111211 to adjust the second rotating member 12111 and adjust the angle index plate 10 to the first angle;

[0066] Specifically, after the angle index plate 10 approaches the first angle by rotating the first rotating member 12211, then rotate the adjustment knob 111211 connected to the first adjustment shaft 11121 to adjust the second rotating member 12111. The rotation of the adjustment knob 111211 will drive the first adjustment shaft 11121 to rotate, and then through the abutting action of the first adjustment shaft 11121 and the second adjustment shaft 11122 on the end of the second rotating member 12111, the second rotating member 12111 slides along the opening direction in the adjustment hole 1111 of the rotating support 111. This sliding of the second rotating member 12111 will further drive the first rotating ring 1211 connected thereto to rotate, thereby realizing a more precise angle adjustment of the angle index plate 10, achieving the precise adjustment of the angle index plate 10 to the required first angle, and meeting the requirements of high-precision calibration.

[0067] Rotate the locking member 12113 to fix the angle index plate 10 at the first angle.

[0068] Specifically, when the angle index plate 10 is precisely adjusted to the first angle through the above steps, finally rotate the locking member 12113 in the locking hole 12112 on the outer wall of the first rotating ring 1211. The locking member 12113 will tightly abut the second rotating cylinder 1222 during rotation, and by increasing the friction force or forming a mechanical block, restrict the rotation of the second rotating cylinder 1222 and the entire rotating disk 12, realizing the firm fixation of the angle index plate 10 at the first angle position, ensuring that during subsequent operations such as angle calibration of the vane-type sideslip angle sensor 40, the angle index plate 10 will not change its angle due to slight external vibrations, and guaranteeing the accuracy and stability of the calibration process.

For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
