Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) manufacturing technology, and in particular to a tooling for testing the strength of UAV wings. Background Technology
[0002] A drone is an unmanned aircraft controlled by radio remote control equipment and its own program control device, or operated completely or intermittently autonomously by an onboard computer. Drones are widely used in aerial photography, agriculture, plant protection, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping and other fields. They have good working performance. During the drone manufacturing process, the wings need to be randomly inspected to ensure that the wing strength can meet the impact resistance test. Inspection fixtures are required during the inspection.
[0003] In the utility model patent with patent publication number CN221477547U, the wing strength testing device for UAV manufacturing, through the coordinated arrangement of a first electric push rod, a connecting frame, a fixed plate, a movable plate, a hydraulic rod, and an impact ball, enables the wing strength testing device for UAV manufacturing to conveniently perform strength testing on multiple aspects of the wing. Although this method can complete the testing work, it also has the limitation that only a single wing can be tested at the same time, which reduces the efficiency of the testing work and is not conducive to practical use.
[0004] Therefore, it is necessary to provide a tooling for testing the strength of UAV wings to solve the above-mentioned technical problems. Utility Model Content
[0005] In response to the above situation and to overcome the shortcomings of the existing technology, this utility model provides a tooling for testing the strength of UAV wings. Although the existing method can complete the testing work, it can only test a single wing at a time, which reduces the efficiency of the testing work and is not conducive to practical use.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A tooling for testing the strength of a UAV wing includes: a worktable, a transmission mechanism, a limiting plate, a support platform, and a hydraulic testing rod;
[0008] A transmission mechanism is installed in the center of the top surface of the workbench. The transmission mechanism consists of a motor, a lead screw, a moving block, a limiting rod, and a placement plate. The motor is connected to the lead screw. A moving block is sleeved on the lead screw and meshes with it. Limiting rods are slidably connected to both sides of the moving block. A placement plate is installed on both sides of the moving block. The wing to be tested is placed in the placement plate. Limiting plates are installed on both outer sides of the transmission mechanism. A positioning port is opened in the center of the limiting plate. Support platforms are installed on both outer sides of the workbench. A hydraulic detection rod is installed on the top surface of each support platform.
[0009] In one embodiment, the outer side of the placement plate has an insertion port into which an wing end is inserted.

The bottom of the hand-tightening bolt is inside the placement plate, and a pressing plate is installed at the bottom of the extension end of the hand-tightening bolt. The pressing plate is generally in the shape of a disc.
[0010] In one embodiment, the bottom surface of the extrusion plate is provided with rubber pads arranged in a circular array, and the rubber pads are used to...
[0011] In one embodiment, the limiting plate and the positioning port are both arc-shaped structures, wherein the end near the motor is the initial segment, and the end away from the motor has a gradually tapering arc surface structure, and a protective pad is installed on the top surface inside the positioning port.
[0012] In one embodiment, a push rod is mounted on the top of the hydraulic detection rod, the shape of which is consistent with the shape of the limiting plate, and the length of the push rod is synchronous with the length of the limiting plate.
[0013] The beneficial effects of this utility model are as follows:
[0014] (1) This utility model has two sets of placement plates and hydraulic detection rods, which can simultaneously detect two wings in the same time period, thereby improving the working efficiency of the overall tooling structure and saving the time of detection operation. By inserting the wing end into the insertion port and tightening the hand-tightening bolt, the extrusion plate is moved down to make contact with the wing end, thus completing the fixation of the wing before detection.

Detailed Implementation
[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.
[0022] like Figures 1-2 As shown, the present invention provides a tooling for testing the wing strength of a UAV, comprising: a workbench 1, a transmission mechanism 2, a limiting plate 3, a support platform 4, and a hydraulic testing rod 5;
[0023] like Figures 1-3 As shown, a transmission mechanism 2 is installed in the center of the top surface of the workbench 1. The transmission mechanism 2 consists of a motor 21, a lead screw 22, a moving block 23, a limiting rod 24, and a placement plate 25. The motor 21 is connected to the lead screw 22. A moving block 23 is sleeved on the lead screw 22 and meshes with it. Limiting rods 24 are slidably connected to both sides of the moving block 23. Placement plates 25 are installed on both sides of the moving block 23. The wing to be inspected is placed in the placement plate 25. Limiting plates 3 are installed on both outer sides of the transmission mechanism 2. A positioning port 31 is opened in the middle of the limiting plate 3. Support platforms 5 are installed on both outer sides of the workbench 1. Hydraulic detection rods 5 are installed on the top surface of the support platforms 5. During operation, by setting two sets of placement plates 25 and hydraulic detection rods 5, two wings can be inspected simultaneously in the same time period, which improves the working efficiency of the overall tooling structure and saves the inspection operation time.
[0024] Preferably, in one embodiment, such as Figures 2-4As shown, the outer side of the placement plate 25 is provided with an insertion port 26, into which the wing end is inserted. The top of the placement plate 25 is provided with a threaded hole, and a hand-tightening bolt 27 is installed inside the threaded hole of the placement plate 25 and engages with it. The bottom of the hand-tightening bolt 27 is inside the placement plate 25, and a pressing plate 28 is installed at the bottom of the extended end of the hand-tightening bolt 27. The pressing plate 28 is generally in the shape of a disc. During operation, by inserting the wing end into the insertion port 26 and tightening the hand-tightening bolt 27, the pressing plate 28 moves down to press and contact the wing end, thus completing the fixation of the wing before inspection.
[0025] Preferably, in one embodiment, such as Figure 4 As shown, the bottom surface of the extrusion plate 28 is arranged in a ring array with rubber pads. The rubber pads help to increase the friction after the two come into contact, while avoiding damage to the wing from the extrusion.
[0026] Preferably, in one embodiment, such as Figures 2-4 As shown, both the limiting plate 3 and the positioning port 31 are arc-shaped structures. The end near the motor 21 is the initial section, and the end away from the motor 21 has a gradually tapering arc surface structure. A protective pad 32 is installed on the inner top surface of the positioning port 31. During operation, after the wing is installed, the free end of the wing passes through the positioning port 31 and is positioned above the hydraulic detection rod 5. The motor 21 drives the lead screw 22 to rotate, which in turn drives the moving block 23 and the placement plate 25 to move linearly under the limit of the limiting rod 24. Due to the arc-shaped tapering structure of the limiting plate 3 and the positioning port 31, the extended part of the wing gradually... The process gradually increases. For example, if three wing deformation tests are required, the hydraulic testing rod 5 is activated immediately after installation to lift the wing extension to test the wing's torsional deformation. When the wing moves to the middle section, the motor 21 stops, allowing the hydraulic testing rod 5 to perform a second lifting test. When the wing moves to the end section, the above steps are repeated to complete the third test. Through the structural design of the limiting plate 3 and the movement of the transmission mechanism 2, torsional testing can be provided at different positions of the wing, improving the overall tooling structure's assistance to the testing equipment, optimizing the wing testing operation steps, and improving the wing testing effect.
[0027] Preferably, in one embodiment, such as Figures 2-4 As shown, a push rod 51 is installed on the top of the hydraulic detection rod 5. The shape of the push rod 51 is consistent with the shape of the limiting plate 3, and the length of the push rod 51 is synchronous with the length of the limiting plate 3. By setting the push rod 51, the single-point detection operation of the hydraulic detection rod 5 is optimized, so that the hydraulic detection rod 5 does not need to adjust the length and position of the detection point.
[0028] Working principle of this utility model:
[0029] During operation, the wing tip is inserted into the slot 26, and the hand-tightening bolt 27 is tightened to move the pressing plate 28 down to press against the wing tip, thus fixing the wing before inspection. After the wing is installed, the free end of the wing passes through the positioning port 31 and is positioned above the hydraulic inspection rod 5. The motor 21 drives the lead screw 22 to rotate, which in turn drives the moving block 23 and the placement plate 25 to move linearly under the limit of the limiting rod 24. Due to the arc-shaped converging structure of the limiting plate 3 and the positioning port 31, the extension of the wing gradually increases during the displacement process. If it is necessary to inspect three... The secondary wing deformation test involves immediately activating the hydraulic testing rod 5 after installation to lift the wing extension and test the wing's torsional deformation. When the wing reaches the middle section, the motor 21 stops, allowing the hydraulic testing rod 5 to perform a second lifting test. This process is repeated when the wing reaches the end section, completing the third test. Through the structural design of the limiting plate 3 and the movement of the transmission mechanism 2, torsional testing can be performed on different parts of the wing, improving the overall tooling structure's support for the testing equipment, optimizing the wing testing operation, and enhancing the wing testing effect.
[0030] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
