DETAILED DESCRIPTION OF THE INVENTION

[0041] The technical solutions of the present invention will be further described in detail below in conjunction with the specific embodiments.

[0042] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where like or similar reference numerals denote like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0043] Embodiment 1: A landing gear detection device for unmanned aerial vehicle production, as Figure 1-7 shown, comprising a chain plate conveying mechanism 1, on which landing gear fixing components for fixing U-shaped or C-shaped landing gears 3 are equidistantly arranged; 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:

[0044] A support frame 2, on which a T-shaped frame 26 is fixed;

[0045] Linkage arms 10, two linkage arms 10 are rotatably installed on the T-shaped frame 26 through a shaft. The two linkage arms 10 are in a scissor structure. The linkage arm 10 on the side close to the T-shaped frame 26 is connected to the T-shaped frame 26 through a clockwork spring;

[0046] A push frame 9, on one outer wall of which a guide frame 8 is fixed. The push frame 9 is slidably installed on the support frame 2 through the guide frame 8;

[0047] Rotating shafts 27, two rotating shafts 27 are rotatably installed at the ends of the two linkage arms 10. The bottom ends of the rotating shafts 27 are rotatably installed with sliding arms 11. A sliding groove is formed on one side of the push frame 9, and one end of the sliding arm 11 is slidably installed in the sliding groove;

[0048] End rods 28, the end rods 28 are fixed to the ends of the linkage arms 10 far from the rotating shafts 27;

[0049] A folding frame 30, at the end of which a guide rod 7 is fixed. The guide rod 7 is slidably connected to the inner wall of the support frame 2, and the guide rod 7 and the support frame 2 are connected through a guide rod spring 12;

[0050] A lifting and moving frame 34, the lifting and moving frame 34 is slidably installed on the folding frame 30. A guiding frame 29 is fixed on the T-shaped frame 26, and the guiding frame 29 is located on the movement path of the lifting and moving frame 34. The two sides at the top of the lifting and moving frame 34 are above the guiding frame 29, and the height of the guiding frame 29 gradually increases along the conveying direction of the chain plate conveying mechanism 1;

[0051] By setting up the chain plate conveying mechanism 1 and the landing gear fixing assembly, the U-shaped or C-shaped landing gear 3 can be fixed on the landing gear fixing assembly 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, by 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 pressing frames 9 to move towards each other for extrusion testing;

[0052] As the landing gear 3 continues to move, it drives the lifting and moving frame 34 to continue moving. 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, thereby resetting each structure and completing the test of the current landing gear 3;

[0053] This method does not require an additional power source, and the timing and duration of the test are both realized based on the conveying of the landing gear 3 by the chain plate conveying mechanism 1, achieving linkage testing based on a mechanical structure. Since there are multiple landing gear fixing assemblies on the chain plate conveying mechanism 1, the landing gear fixing assemblies without the landing gear 3 installed will not trigger the test, which has high reliability and strong practicability.

[0054] For the convenience of structural reset; as Figure 7 shown, collar rings 35 are rotatably installed on the end rod 28 and the rotating shaft 27, and the two collar rings 35 on the same side are connected by a spring telescopic rod 24;

[0055] By setting up the spring telescopic rod 24 and the collar rings 35, the opening degree of the linkage arm 10 can be fixed when it is not under external force, facilitating timely detection operations; and after the test is completed, each structure can be reset based on the guide rod spring 12, the spiral spring and the spring telescopic rod 24.

[0056] For the purpose of improving the test smoothness; as Figure 7 shown, a linkage wheel 33 is rotatably installed on the lifting and moving frame 34 through a roller frame, and the guiding frame 29 is located on the movement track of the linkage wheel 33;

[0057] By setting up the linkage wheel 33, the friction with the guiding frame 29 can be reduced, making the movement of the structure smoother.

[0058] For the convenience of adjusting 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 connected to the inner wall of one side of the lifting and moving frame 34 by means of a thread;

[0059] 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.

[0060] To facilitate the fixation of the landing gear 3; as Figure 3 、 Figure 4 shown, the landing gear fixing assembly includes:

[0061] The first mounting seat 6 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;

[0062] The second mounting seat 5 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;

[0063] The extrusion part 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.

[0064] Among them, the extrusion part includes:

[0065] The sliding frame 17 is provided with a sliding groove on the second mounting seat 5. The sliding frame 17 slides in the sliding groove, and one end of the sliding frame 17 is connected to the sliding groove through a sliding frame spring 22;

[0066] The pressing block 15 is fixed with a guiding column 23 at one end. The guiding column 23 slides inside the sliding frame 17, the pressing block 15 slides inside the sliding groove, and the pressing block 15 and the sliding frame 17 are connected through a pressing block spring 16. A groove adapted to the landing gear 3 is provided on the side of the pressing block 15 close to the landing gear 3;

[0067] By setting the extrusion part, during the test process, the pushing and pressing frame 9 can be used to extrude the sliding frame 17, and then the landing gear 3 can be extruded and tested through the pressing block 15. By adopting structures such as the pressing block spring 16, the landing gear 3 can be better detected while avoiding structural jamming.

[0068] To improve the structural smoothness; as Figure 4 shown, a roller 13 is rotatably mounted at one end of the sliding frame 17 away from the pressing block 15;

[0069] By setting the roller 13, the frictional force of the structure can be reduced during the extrusion of the pushing and pressing frame 9, and the test smoothness can be improved; preferably, two or more rollers 13 are provided at the end of the sliding frame 17 to better transmit the force.

[0070] To facilitate centering; as Figure 4As shown, a moving groove is formed in the first mounting seat 6. The clamping frame 4 is slidably mounted in the moving groove of the first mounting seat 6. A rolling ball 20 is movably mounted at the bottom of the clamping frame 4. The rolling ball 20 rolls in the moving groove. The clamping frame 4 and the first mounting seat 6 are connected by a clamping frame spring 21.

[0071] By providing structures such as the clamping frame spring 21, when testing, the landing gear 3 can be more evenly subjected to extrusion force by the pushing frames 9 on both sides, ensuring the reliability of the test.

[0072] Therefore, the stiffness coefficient of the clamping frame spring 21 should not be too large to reduce errors.

[0073] In order to better detect the test results; as Figure 4 shown, a plurality of marking lines 14 are provided on the top of the second mounting seat 5. A CCD shooting component 25 is mounted on the T-shaped frame 26.

[0074] By providing the CCD shooting component 25, based on the images obtained by the CCD shooting component 25, the marking lines 14 are used to judge the force skew degree of the landing gear 3, so as to determine whether the test is qualified.

[0075] For specific image processing and image analysis techniques, reference can be made to the existing technology and will not be elaborated here.

[0076] For the convenience of testing; as Figure 4 shown, a mounting plate 19 is movably mounted up and down on one inner wall of the clamping frame 4. A fixing screw 18 for fixing the mounting plate 19 is connected to one inner wall of the clamping frame 4 by threads.

[0077] By providing structures such as the mounting plate 19, the height of the mounting plate 19 can be adjusted according to requirements. 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.

[0078] 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 technology.

[0079] The above is only a preferred specific embodiment 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, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
