Description

Technical Field

[0001] This utility model relates to the field of product strength testing technology, and in particular to a wing mechanism strength testing device. Background Technology

[0002] The wing mechanism is a crucial component for balancing the flight attitude of an aircraft. During flight, the wing mechanism withstands atmospheric drag and pressure, making its static strength and stiffness particularly important. A series of tests are required for the wing mechanism of a particular aircraft, with static strength and stiffness being the final test. The requirements for static strength and stiffness of the wing mechanism are: under a certain load, the maximum deflection of the wing should be less than a safe value, and after unloading, the wing should exhibit no plastic deformation. Existing technologies typically use ordinary tension / compression machines for loading, and deflection measurement (i.e., deformation measurement) requires manual operation and calculation. However, this method cannot provide a direct and convenient way to obtain deflection values, and the testing process also requires simultaneously and efficiently testing the deformation of two symmetrical winglets. Utility Model Content

[0003] In view of this, in order to perform this test on the wing mechanism by both loading and measuring the deflection, this utility model proposes a wing mechanism strength testing device, which is suitable for testing the static strength and stiffness of such a mechanism.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A winglet mechanism strength testing device includes a base plate fixedly connected to the straightening machine workbench, and further includes: The two balance support components are detachably mounted on the left and right sides of the base plate at the same height at the top, and are used to level the blades. A wing fixing assembly is fixedly disposed on the upper end of the base plate and located between the two balance support assemblies, for fixing the wing mechanism; A balancing block assembly, located above the vane mechanism, is used to apply loads to the vanes of the vane mechanism.

[0005] As a further improvement to the above technical solution: An optimized version of the above technical solution is that the balance block assembly includes a placement base and a balance support fixedly disposed on the placement base. When the wing mechanism is placed on the wing fixing assembly, the upper end of the balance support is in contact with the lower end face of the wing of the wing mechanism.

[0006] An optimized version of the above technical solution is that the wing fixing assembly includes a support fixedly disposed parallel to the upper end of the base plate, a clamping seat with one end hinged to the support and the other end fixed and loosened by a hinge screw, a support sleeve is placed in the space formed by the clamping seat and the support, and the wing mechanism can be sleeved on the outer wall of the support sleeve.

[0007] An optimized version of the above technical solution is that the balancing block assembly includes a connecting seat and pressure blocks disposed on the left and right sides of the connecting seat. When the wing mechanism is placed on the wing fixing assembly, the lower end of the pressure block contacts the upper surface of the wing of the wing mechanism.

[0008] An optimized version of the above technical solution is that the connecting seat has a centering line in the middle.

[0009] An optimized version of the above technical solution includes a centering block, which can be detachably mounted on the upper end of the wing mechanism. The centering block is used in conjunction with the centering scribe line to adjust the center position.

[0010] Compared with existing technologies, the beneficial effects of this utility model are: This invention employs a straightening machine, which can accurately measure the bending shape of a product when subjected to applied pressure. Combined with the centering and clamping parts in a dedicated testing device, it can test the deformation of two symmetrical blades in a balanced manner. This method is intuitive and efficient, satisfying the requirement of both loading and deflection measurement. Furthermore, the device has a simple structure and is easy to operate. The entire testing process is intuitive and accurate, ensuring consistent quality and reliable component performance. Attached Figure Description

[0016] As attached Figure 1 With appendix Figure 2 As shown, this technical solution is mainly used for the attached Figure 3 The strength test of the wing mechanism 12 shown is illustrated in the attached figure. The wing mechanism 12 has four wing seats arranged in a circular array on the wing sleeve, with a wing installed in each seat. Therefore, the specific details of this technical solution are as follows: The testing device consists of a connecting seat 8, a pressure block 9, a centering block 11, a clamping block, a placement base 6, a balance support seat 7, a base plate 1, a support 2, a support sleeve 5, and standard screws, nuts, and pins of various specifications.

[0017] Screws are used to install two pressure blocks 9 at both ends of the connecting seat 8 to assemble a balance pressure block 9 assembly. The center of the connecting seat 8 is engraved with a centering line 10. There is also a centering block 11 that can be detached and installed on the vane seat, which works in conjunction with the centering line 10. The base 6 and the balance support 7 are assembled together using screws to form a balance support assembly.

[0018] Two supports 2 are installed on the corresponding positions of the base plate 1 with screws. One end of the support 2 is connected to one end of the clamping seat 3 with a pin, and the other end is installed with a hinge screw 4 of the same specification pin.

[0019] It also includes a support sleeve 5 for connecting the vane mechanism 12; The method for detecting the blade mechanism 12 using the above technical solution is as follows: Step 1: Disassemble the two symmetrical wings of the wing mechanism 12, which has four wings evenly installed; Step 2: Place the disassembled blade mechanism 12 onto the outer wall of the support sleeve 5, place both ends of the support sleeve 5 on the two supports 2, and fix the two ends of the support sleeve 5 by rotating the clamping seat 3 and using hinge screws 4. Step 3: Place the base plate 1 on the straightening machine workbench and place the balance support components on the corresponding positions on the left and right sides of the base plate 1 so that the blades at both ends of the blade mechanism 12 are kept horizontal. Therefore, the upper end of the balance support seat 7 should be at the same height and in contact with the lower surface of the blades on both sides of the blade mechanism 12. Step 4: Insert the centering block 11 into the wing mounting hole of the upper wing seat of the wing mechanism 12 after disassembly; Step 5: Ensure that the centering block 11 coincides with the pressure center of the straightening machine, and ensure that the center symmetry error of the two supports 2 is ≤0.1. Finally, use screws to fix the base plate 1 on the workbench. Step 6: Place the balance block 9 assembly on the upper surface of the vane mechanism 12, so that the pressure blocks 9 at both ends are located at the two ends of the vane on both sides of the vane mechanism 12. At the same time, adjust the position of the balance block 9 assembly so that the centering line 10 on the connecting seat 8 coincides with the center plane of the centering block 11. The positions of the pressure blocks 9 at both ends are the positions where the vane is subjected to force. Ensure that the center of the balance block 9 assembly coincides with the pressure center of the straightening machine. Step 7: Remove the centering block 11 and the balance support assembly; Step 8: Start the straightening machine and slowly apply load to the balance block 9 assembly. The applied load is the design load minus the weight of the balance block 9 assembly. When the load is fully applied to the set value, the straightening machine accurately measures the bending shape value of the two ends of the vane. If it is less than or equal to the set value, the deflection is qualified. Unload the load. If the vane has no plastic deformation, the strength is qualified; otherwise, it is unqualified. Step 9: Remove the two blades on the tested blade mechanism 12, install the untested blades on the other two blade seats, and repeat steps 2 to 8. The deflection of the four blades of the blade mechanism 12 is qualified, with no plastic deformation. The static strength and stiffness of the blade mechanism 12 are qualified.

[0020] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
