Detailed implementation manners

[0021] The technical solutions of the present invention will be further described in detail below in conjunction with the specific implementation manners.

[0022] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0023] Embodiment 1: A landing gear detection device for UAV production, as Figures 1-7 shown, includes a chain plate conveying mechanism 1, and landing gear fixing components for fixing U-shaped or C-shaped landing gears 3 are equidistantly arranged on the chain plate conveying mechanism 1; a detection mechanism is arranged on the chain plate conveying mechanism 1, and the detection mechanism is located on the movement path of the landing gear 3. The detection mechanism includes: A support frame 2, on which a T-shaped frame 26 is fixed; Linkage arm 10, two linkage arms 10 are rotatably mounted on the T-shaped frame 26 through a shaft. The two linkage arms 10 are in a scissor structure. The linkage arm 10 close to the T-shaped frame 26 is connected to the T-shaped frame 26 through a clockwork spring; Pushing frame 9, a guiding frame 8 is fixed on the outer wall of one side of the pushing frame 9. The pushing frame 9 is slidably mounted on the support frame 2 through the guiding frame 8; Rotating shaft 27, two rotating shafts 27 are rotatably mounted at the ends of the two linkage arms 10. A sliding arm 11 is rotatably mounted at the bottom end of the rotating shaft 27. A sliding groove is formed on one side of the pushing frame 9, and one end of the sliding arm 11 is slidably mounted in the sliding groove; End rod 28, the end rod 28 is fixed at the end of the linkage arm 10 far from the rotating shaft 27; Folding frame 30, a guiding rod 7 is fixed at the end of the folding frame 30. The guiding rod 7 is slidably connected to the inner wall of the support frame 2. The guiding rod 7 and the support frame 2 are connected through a guide rod spring 12; Lifting and moving frame 34, the lifting and moving frame 34 is slidably mounted on the folding frame 30. A guiding frame 29 is fixed on the T-shaped frame 26. The guiding frame 29 is located on the movement path of the lifting and moving frame 34. The two sides of the top of the lifting and moving frame 34 are located above the guiding frame 29. The height of the guiding frame 29 gradually increases along the conveying direction of the chain plate conveying mechanism 1; By setting the chain plate conveying mechanism 1 and the landing gear fixing component, a U-shaped or C-shaped landing gear 3 can be fixed on the landing gear fixing component, with its opening facing the rear of the conveying direction. During the conveying of the landing gear 3, it contacts the lifting and moving frame 34, thereby driving the folding frame 30 to move. Thus, using the folding frame 30, the end rods 28 at the ends of the two linkage arms 10 are squeezed inward. Since the two linkage arms 10 form a scissor structure, the rotating shaft 27 at the other end of the linkage arm 10 pulls the sliding arm 11 to move, thereby prompting the two pushing frames 9 to move towards each other for extrusion testing; As the landing gear 3 continues to move, it drives the lifting and moving frame 34 to continue to move. Since the height of the guiding frame 29 gradually increases along the conveying direction of the chain plate conveying mechanism 1, the height of the lifting and moving frame 34 is continuously lifted until it disengages from the landing gear 3, so that each structure can be reset to complete the test of the current landing gear 3; This method does not require an additional power source, and the timing and time of the test are both realized based on the conveying of the landing gear 3 by the chain plate conveying mechanism 1. The linkage test is realized based on the mechanical structure. Since there are multiple landing gear fixing components on the chain plate conveying mechanism 1, the landing gear fixing components without the landing gear 3 installed will not trigger the test, with high reliability and strong practicability.

[0024] For facilitating the reset of the structure; as Figure 7 shown, collar 35 is rotatably mounted on the end rod 28 and the rotating shaft 27. Two collars 35 on the same side are connected by a spring telescopic rod 24; By setting the spring telescopic rod 24 and the collar 35, the opening degree of the linkage arm 10 can be fixed when no external force is applied, so as to facilitate timely detection operations; and after the test is completed, each structure can be reset based on the guide rod spring 12, the clockwork spring and the spring telescopic rod 24.

[0025] To improve the test fluency; as Figure 7 shown, a linkage wheel 33 is rotatably installed on the lifting and moving frame 34 through a roller frame, and the guide frame 29 is located on the movement track of the linkage wheel 33; By setting the linkage wheel 33, the friction with the guide frame 29 can be reduced, making the movement of the structure smoother.

[0026] To facilitate the adjustment of the test position; as Figure 7 shown, a linkage plate 32 is slidably installed at the bottom end of the lifting and moving frame 34, and a threaded knob 31 for fixing the linkage plate 32 is threadedly connected to the inner wall of one side of the lifting and moving frame 34; By setting the linkage plate 32, the effective length of the extended linkage plate 32 can be adjusted, thereby changing the timing of the linkage plate 32 disengaging from the landing gear 3, achieving the purpose of adjusting the movement distance of the pushing and pressing frame 9.

[0027] To facilitate the fixation of the landing gear 3; as Figure 3 、 Figure 4 shown, the landing gear fixing assembly includes: A first mounting seat 6, which is detachably mounted on the chain plate of the chain plate conveying mechanism 1. A clamping frame 4 is mounted on the first mounting seat 6, and the landing gear 3 is detachably fixed on the clamping frame 4; A second mounting seat 5, which is detachably mounted on the chain plate of the chain plate conveying mechanism 1. The second mounting seat 5 is located at the rear side in the conveying direction of the clamping frame 4, and the top surface of the second mounting seat 5 supports the bottom surface of the landing gear 3; An extrusion part, which is mounted on the second mounting seat 5. Two extrusion parts are located on both sides of the landing gear 3, and the extrusion part is adapted to the position of the pushing and pressing frame 9.

[0028] Among them, the extrusion part includes: A sliding frame 17. A sliding groove is provided on the second mounting seat 5, and the sliding frame 17 slides in the sliding groove. One end of the sliding frame 17 is connected to the sliding groove through a sliding frame spring 22; A pressing block 15. One end of the pressing block 15 is fixed with a guide post 23. The guide post 23 slides in the inner wall of the sliding frame 17, and the pressing block 15 slides in the inner wall of the sliding groove. A pressing block spring 16 is connected between the pressing block 15 and the sliding frame 17. A groove adapted to the landing gear 3 is provided on the side of the pressing block 15 close to the landing gear 3; By setting the extrusion part, during the test, the sliding carriage 17 can be extruded by the pushing frame 9, and then the landing gear 3 can be extruded and tested by the pressing block 15. By adopting structures such as the pressing block spring 16, while being able to better detect the landing gear 3, the structure jamming is avoided.

[0029] To improve the structural smoothness; as Figure 4 shown, a roller 13 is rotatably installed at one end of the sliding carriage 17 away from the pressing block 15; By setting the roller 13, during the extrusion of the pushing frame 9, the friction of the structure can be reduced, and the test smoothness can be improved; preferably, two or more rollers 13 are arranged at the end of the sliding carriage 17 for better force transmission.

[0030] To facilitate centering; as Figure 4 shown, a moving groove is formed on the first mounting seat 6, the clamping frame 4 is slidably installed in the moving groove of the first mounting seat 6, a rolling ball 20 is movably installed at the bottom of the clamping frame 4, the rolling ball 20 rolls in the moving groove, and the clamping frame 4 and the first mounting seat 6 are connected by a clamping frame spring 21; By setting structures such as the clamping frame spring 21, during the test, the extrusion force can be more evenly applied to the landing gear 3 by the pushing frames 9 on both sides, ensuring the reliability of the test; Therefore, the stiffness coefficient of the clamping frame spring 21 should not be too large to reduce errors.

[0031] To better detect the test results; as Figure 4 shown, a plurality of marking lines 14 are arranged on the top of the second mounting seat 5, and a CCD shooting component 25 is installed on the T-shaped frame 26; By setting the CCD shooting component 25, based on the image obtained by the CCD shooting component 25, the force skewing degree of the landing gear 3 is judged by using the marking lines 14, so as to determine whether the test is qualified; Specific image processing and image analysis technologies can refer to the existing technologies and will not be elaborated here.

[0032] To facilitate the test; as Figure 4 shown, a mounting plate 19 is movably installed up and down on one inner wall of the clamping frame 4, and a fixing screw 18 for fixing the mounting plate 19 is connected to one inner wall of the clamping frame 4 by thread; By setting structures such as the mounting plate 19, the height of the mounting plate 19 can be adjusted according to requirements, and the mounting plate 19 is used to contact the linkage plate 32 or the lifting and moving frame 34 instead of the landing gear 3, so as to complete the test.

[0033] For the parts not fully disclosed in the present invention, those skilled in the art can ensure the smooth implementation of the solution of the present invention based on common sense, normal thinking logic and existing technologies.

[0034] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
