Description

Technical Field

[0001] The present application relates to the technical field of air rudder torsion plate groups, and in particular to a detection tool for torsion plate groups. Background Art

[0002] As an important actuator for adjusting the attitude of the aircraft, the air rudder needs to withstand aerodynamic and aerodynamic thermal loads for a long time during flight. Generally, the air rudder is an integral unfolding structure. As the structural integration of the launch box becomes higher and higher, the maximum envelope space of the launch box becomes more and more compact. Therefore, the air rudder needs to be improved and optimized from the original overall solution to a foldable solution, that is, the aircraft air rudder is loaded into the launch box in a folded state, and the air rudder automatically returns to the unfolded state when the aircraft ignites and launches out of the box. The torsion bar provides torque for the folding and unfolding of the air rudder. Because the maximum torsion angle of the torsion bar cannot adapt to the folding angle of the air rudder, the use of a torsion plate group instead of a torsion bar can better adapt to the large torsion angle function of the air rudder folding.

[0003] The torque of the torsion plate group as a whole needs to be tested to obtain the performance status of the torsion plate group. The existing measuring equipment mainly includes a torsion machine designed for automobile torsion bars. Its structure and function are similar to those of a lathe. The operation is relatively complicated and requires professional skills training before operation. At the same time, the equipment chuck is only suitable for rod-shaped torsion bar measurement. The operation is complicated, and forced testing of the torsion plate group will lead to inaccurate test results and easily cause certain damage to the torsion plate group in the air rudder.

DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. The specific structural and functional details disclosed herein are only used to describe the exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments described herein.

[0027] Figure 1 A cross-sectional view of the detection tooling during detection operation is provided for the embodiment of the present application. Figure 2 A side view of the inspection tool during inspection operation is provided for the embodiment of the present application.

[0028] A detection tool for a twisting plate assembly 800, the detection tool comprising a base 100, a first assembly part 200, a second assembly part 300 and an operating part 301, wherein:

[0029] like Figure 1 As shown, Figure 1 A cross-sectional view of the inspection tooling during inspection operation is provided for the embodiment of the present application. The base 100 serves as a relative operating reference, which is used to carry and fix the first assembly 200 and the second assembly 300. Correspondingly, the first assembly 200 and the second assembly 300 are respectively maintained at relative positions based on the base 100, so that when configuring the relevant specification parameters of the first assembly 200 and the second assembly 300, the uniformity can be higher, and when the base 100 is moved as a whole, the relevant positions of the first assembly 200 and the second assembly 300 can be kept relatively fixed, thereby improving reliability and avoiding relative displacement caused by repeated operations.

[0030] like Figure 1 As shown, the first assembly part 200 is mounted on the base 100 and is used to connect one end of the twisting plate group 800. The first assembly part 200 is provided with a first space for accommodating the twisting plate group 800. The first assembly part 200 can limit the rotation of the twisting plate group 800. It should be noted that the cross-section of the first assembly frame at least a certain distance matches the cross-section of the twisting plate group 800. By matching the twisting plate group 800 with the first assembly part 200, when the first assembly part 200 remains relatively stable, one end of the twisting plate group 800 can be kept relatively stable, which is convenient for twisting the twisting plate group 800.

[0031] like Figure 1As shown, the second assembly part 300 is movably mounted on the base 100 and is arranged at an interval with the first assembly part 200. The second assembly part 300 is used to connect the other end of the torsion plate group 800, and the second assembly part 300 is provided with a second space for accommodating the torsion plate group 800. The second assembly part 300 can drive the torsion plate group 800 to rotate synchronously. It should be noted that the cross-section of the second assembly frame at least a certain distance matches the cross-section of the torsion plate group 800. Through the matching of the torsion plate group 800 and the second assembly part 300, when the second assembly part 300 rotates, the other end of the torsion plate group 800 can be kept stable and rotate synchronously with the second assembly part 300, so as to facilitate the twisting operation of the torsion plate group 800.

[0032] like Figure 1 As shown, the operating member 301 is detachably connected to the second assembly member 300, and is used to drive the second assembly member 300 to rotate so as to twist the torsion plate group 800. The operating member 301 serves as the input end of the external force, and drives the second assembly member 300 to complete the twisting relative to the first assembly member 200 through the operating member 301.

[0033] It should be noted that, in order to ensure reliable operation, when the cross-section of the torsion plate group 800 is rectangular, the cross-sections of the first space and the second space are also rectangular, so as to maintain the matching relationship between the first assembly part 200 , the second assembly part 300 and the torsion plate group 800 .

[0034] like Figure 1As shown, in an optional embodiment, the working principle of the detection tool for the torsion plate group 800 in the present application is: the detection tool includes a base 100, and a first assembly part 200 and a second assembly part 300 on the base 100, the first assembly part 200 is mounted on the base 100, and is used to connect one end of the torsion plate group 800, the first assembly part 200 is provided with a first space for accommodating the torsion plate group 800, the second assembly part 300 is movably mounted on the base 100, and is arranged at an interval with the first assembly part 200, the second assembly part 300 is used to connect the other end of the torsion plate group 800, and the second assembly part 300 is provided with a second space for accommodating the torsion plate group 800, and the second assembly part 300 is detachably connected to the second assembly part 300, the operating part 301 is used to drive the second assembly part 300 to rotate so as to twist the torsion plate group 800, and when the torsion plate group 800 is being operated 0, the two ends of the twisting plate group 800 are respectively extended into the first space and the second space, and are respectively connected to the first assembly part 200 and the second assembly part 300 to complete the detection and assembly of the twisting plate group 800. The first assembly part 200 can limit the rotation of the twisting plate group 800, and the second assembly part 300 can drive the twisting plate group 800 to rotate synchronously. By applying an external force on the operating part 301, the second assembly part 300 is driven to rotate relatively, and the corresponding middle part of the twisting plate group 800 is relatively twisted. According to the detection requirements, different sizes of external forces are applied to the operating part 301, and then the performance status of the twisting plate group 800 is obtained, so that it can be quickly determined whether the twisting plate group 800 meets the set technical requirements. The operation is simple and the detection results are reliable. The first assembly part 200 and the second assembly part 300 improve the detection protection of the twisting plate group 800, and the efficiency is higher under repeated detection operations.

[0035] like Figure 1 , Figure 2 As shown, in an optional embodiment, the detection tooling includes an indicator, which is arranged between the second assembly part 300 and the base 100 and is used to output the torque value or the torsion angle of the torsion plate group 800. By applying an external force on the operating part 301, the second assembly part 300 is driven to rotate relatively, and the corresponding middle part of the torsion plate group 800 undergoes relative torsion, and the torque value or the torsion angle applied to the operating part 301 is output through the indicator, so that when performing detection operations, the specific numerical values ​​under the detection state can be obtained more easily and accurately, and the specific numerical values ​​can be used as detection conditions to complete the detection operations more accurately and quickly.

[0036] like Figure 1 , Figure 2As shown, in an optional embodiment, the indicator includes a dial 401 and a pointer 403, the dial 401 is fixedly connected to the base 100, the pointer 403 is fixedly connected to the second assembly part 300, and the dial 401 is provided with scale marks 402 corresponding to different torque values ​​or torsion angles, and when the second assembly part 300 rotates, the pointer 403 rotates synchronously to obtain the torque value or torsion angle corresponding to the scale mark 402.

[0037] Specifically, by calibrating the torque value or torsion angle applied to the operating member 301 and the scale mark 402 on the dial 401 accordingly, so that the scale mark 402 can accurately correspond to the torque value or torsion angle applied to the operating member 301, the dial 401 remains relatively fixed, and the pointer 403 rotates synchronously with the second assembly 300 to maintain the corresponding numerical output.

[0038] When the scale plate 401 is installed, it can be fixed by installing screws 404.

[0039] like Figure 1 , Figure 2 As shown, in an optional embodiment, a first positioning platform 500 is provided on the base 100, and the first assembly component 200 is detachably provided on the first positioning platform 500. The first positioning platform 500 provides an accurate installation position for the first assembly component 200, and the first assembly component 200 can be separated from the first positioning platform 500 to facilitate the assembly of the twist plate group 800.

[0040] like Figure 1 , Figure 2 As shown, in an optional embodiment, a set screw 501 is threadedly provided on the first positioning platform 500, and one end of the set screw 501 can be pressed onto the first assembly part 200. After the assembly operation of the first assembly part 200 and the first positioning platform 500 is completed, the reliability of the first assembly part 200 during operation is maintained by the set screw 501, and the first assembly part 200 is limited from being separated or loosened from the first positioning platform 500 during the twisting process of the torsion plate group 800, thereby improving reliability.

[0041] like Figure 1 , Figure 2As shown, in an optional embodiment, a removable first positioning pin 502 is provided on the first assembly part 200, and the first positioning pin 502 is used to simultaneously penetrate the first assembly part 200 and one end of the twisting plate group 800. After completing the assembly operation of the twisting plate group 800 and the first assembly part 200, the first positioning pin 502 simultaneously penetrates the first assembly part 200 and one end of the twisting plate group 800 to maintain the reliability of the twisting plate group 800 during operation, limit the twisting plate group 800 from separating or loosening from the first assembly part 200 during the twisting process, and improve reliability.

[0042] like Figure 1 , Figure 2 As shown, the second assembly part 300 is provided with a detachable second positioning pin 601, and the second positioning pin 601 is used to simultaneously penetrate the second assembly part 300 and the other end of the twisting plate group 800. After completing the assembly operation of the twisting plate group 800 and the second assembly part 300, the second positioning pin 601 simultaneously penetrates the second assembly part 300 and the other end of the twisting plate group 800 to maintain the reliability of the twisting plate group 800 during operation, limit the twisting plate group 800 from separating or loosening from the second assembly part 300 during the twisting process, and improve reliability.

[0043] like Figure 1 , Figure 2 As shown, in an optional embodiment, a second positioning platform 600 is provided on the base 100, and the second assembly part 300 is detachably provided on the second positioning platform 600, and the first assembly part 200 is coaxially arranged with the second assembly part 300, and the second positioning platform 600 provides an accurate installation position for the second assembly part 300, and the second assembly part 300 can be separated from the second positioning platform 600 to facilitate the assembly of the torsion plate group 800, and the second assembly part 300 is kept coaxially arranged with the first assembly part 200 by the second positioning platform 600, so that the torsion plate group 800 can maintain a relatively reliable state after the assembly is completed and before twisting, so as to avoid the torsion plate group 800 from bending under the action of external force after repeated operations.

[0044] like Figure 1 , Figure 2 As shown, in an optional embodiment, a bearing 602 is provided between the second positioning platform 600 and the second assembly part 300 to maintain the smoothness and stability of the rotation process of the second assembly part 300 and reduce the difficulty and intensity of the detection operation.

[0045] like Figure 1 , Figure 2As shown, in an optional embodiment, the first space includes a connected connecting section 201 and a accommodating section 202, the inner wall of the connecting section 201 is in contact with the outer wall of the twisting plate group 800, and the inner wall of the accommodating section 202 is gap-fitted with the outer wall of the twisting plate group 800. The connecting section 201 keeps the twisting plate group 800 in a relatively stable position under the constraint of the first assembly part 200 to facilitate relative twisting between the two ends of the twisting plate group 800. The accommodating section 202 provides displacement space for the middle part of the twisting plate group 800 during the twisting process, avoids interfering with the twisting of the middle part of the twisting plate group 800, keeps the detection process reliable, and improves the accuracy of the detection results.

[0046] like Figure 1 , Figure 2 As shown, in an optional embodiment, the operating member 301 and the second assembly member 300 are connected via a flat key 700, which not only facilitates the separation of the operating member 301 and the second assembly member 300, but also can reliably drive the second assembly member 300 to rotate when the operating member 301 rotates.
