Description

Technical Field

[0001] This utility model relates to the field of positioning fixtures, and in particular to a positioning fixture for mounting drone wings. Background Technology

[0002] As unmanned aerial vehicles (UAVs), drones have been widely used in numerous fields such as aerial surveying, agricultural plant protection, power line inspection, emergency rescue, and logistics transportation due to their advantages of flexibility, ease of operation, and relatively low cost. With the continuous development of UAV technology, the requirements for their flight performance, stability, and safety are increasing. As the core component for generating lift, the quality of the wing's installation directly affects the overall performance of the UAV. The installation of the UAV wing is a critical step in the UAV production and assembly process, requiring that the connection accuracy, angle, and tightness between the wing and the fuselage meet design standards. Deviations in wing installation can lead to uneven stress during flight, causing problems such as fuselage vibration and unstable flight attitude. In severe cases, it can even cause the UAV to lose control, crash, and result in property damage or safety accidents.

[0003] In the installation of drone wings, positioning fixtures play an irreplaceable and crucial role. They precisely position and securely fix the drone fuselage, ensuring that the fuselage does not shift during wing-to-fuselage assembly. This prevents deviations in wing installation caused by external forces and guarantees that connecting bolts are installed smoothly and tightened to the specified degree. Furthermore, efficient positioning fixtures significantly improve the installation efficiency of wings and fuselages, reduce the labor intensity of manual operations, and, more importantly, effectively ensure the consistency of drone product quality in mass production scenarios. Therefore, they are core equipment for ensuring the accuracy and reliability of drone wing installation. Utility Model Content

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a UAV wing mounting and positioning fixture includes a mounting bracket 1. A positioning support frame 2 and a downward pressing and fixing structure 3 are fixedly mounted on the mounting bracket 1. The downward pressing and fixing structure 3 is located above the positioning support frame 2. The positioning support frame 2 consists of a connecting plate 6, support columns 7, and first arc-shaped rubber pads 9. There are four support columns 7, all fixedly mounted on the upper end of the connecting plate 6. There are four first arc-shaped rubber pads 9, each fixedly mounted on one of the four support columns 7. The downward pressing and fixing structure 3 consists of a cylinder 10, a mounting plate 11, a Z-shaped plate 12, a mounting rod 14, and a buffer spring. The system comprises an anti-detachment plate 15, an arc-shaped plate 16, an arc-shaped plate 17, and a second arc-shaped rubber pad 18. The mounting plate 11 is fixedly sleeved on the piston rod of the cylinder 10. Four Z-shaped plates 12 are fixedly installed on the outer walls of the four mounting plates 11. Four mounting rods 14 are slidably installed on the four Z-shaped plates 12. Four buffer springs 15 are sleeved on the four mounting rods 14. Four anti-detachment plates 16 are fixedly installed on the upper ends of the four mounting rods 14. Four arc-shaped plates 17 are fixedly installed on the lower ends of the four mounting rods 14. The second arc-shaped rubber pad 18... Four shaped rubber pads 18 are fixedly installed on the inner walls of four arc-shaped plates 17. By setting a positioning support frame 2 consisting of a connecting plate 6, a support column 7, and a first arc-shaped rubber pad 9 on the mounting bracket 1, and a downward pressing and fixing structure 3 consisting of a cylinder 10, a mounting plate 11, a Z-shaped plate 12, a mounting rod 14, a buffer spring 15, an anti-detachment plate 16, an arc-shaped plate 17, and a second arc-shaped rubber pad 18, the UAV fuselage can be accurately positioned and firmly fixed, ensuring that the fuselage will not shift during the assembly of the wing and the fuselage, thereby avoiding interference from external forces. This fixture, designed to prevent wing installation deviations, ensures the connection bolts are installed smoothly and tightened to the specified degree. Its rational structure and easy operation significantly improve the installation efficiency of the wing and fuselage, reducing manual labor intensity. In mass production scenarios, it effectively guarantees the consistency of drone product quality, thereby ensuring the drone's flight performance, stability, and safety. It reduces the risk of problems such as fuselage vibration, unstable flight attitude, and even drone loss of control or crashes caused by wing installation deviations, thus minimizing property damage and safety accidents.

[0021] Specifically, the mounting bracket 1 consists of a base plate 4 and an L-shaped support frame 5. The L-shaped support frame 5 is fixedly installed on the upper rear side of the base plate 4. The connecting plate 6 on the positioning support frame 2 is fixedly installed on the upper end of the base plate 4 by bolts. An arc-shaped groove 8 is opened at the upper end of the support column 7. A first arc-shaped rubber pad 9 is fixedly installed on the inner wall of the arc-shaped groove 8. The cylinder 10 on the pressing and fixing structure 3 is fixedly installed on the upper end of the L-shaped support frame 5. The mounting plate 11 is located inside the L-shaped support frame 5. The Z-shaped plate 12 on the pressing and fixing structure 3 has mounting holes 13. The mounting hole 13 passes through the Z-shaped plate 12 vertically, and the mounting rod 14 slides vertically within the mounting hole 13. The anti-detachment plate 16 is located above the Z-shaped plate 12, the buffer spring 15 is located below the Z-shaped plate 12, and the four arc-shaped plates 17 are located directly above the four support columns 7. The curvature of the arc groove 8 and the arc plate 17 is adapted to the curvature of the UAV arm to ensure that the UAV arm can fit tightly with the first arc-shaped rubber pad 9 and the second arc-shaped rubber pad 18, thereby achieving precise fixation and positioning of the fuselage and ensuring the accuracy of the wing-fuselage assembly.

[0022] When assembling the drone wings and fuselage, the drone fuselage is first placed on the four support columns 7 of the positioning support frame 2, so that the fuselage arms contact the first arc-shaped rubber pads 9 on the support columns 7. Initial positioning is achieved by utilizing the arc-shaped structure of the first arc-shaped rubber pads 9 to match the contour of the fuselage arms. Next, the cylinder 10 of the pressing and fixing structure 3 is activated. The piston rod of the cylinder 10 extends, causing the mounting plate 11 to move downwards. The mounting plate 11 then moves the Z-shaped plate 12 downwards simultaneously. The Z-shaped plate 12, through the mounting rod 14, causes the arc-shaped plate 17 and the second arc-shaped rubber pad 18 to move closer to the fuselage arms. When the second arc-shaped rubber pad 18 contacts the top of the fuselage arm, as the piston rod of the cylinder 10 continues to extend, the Z-shaped plate 12 slides downwards on the mounting rod 14 through the mounting hole 13. At this time, the buffer spring 15 is... The Z-shaped plate 12 is compressed and generates elasticity, causing the second arc-shaped rubber pad 18 to press tightly against the fuselage. At this time, the fuselage is firmly fixed by the positioning support frame 2 and the downward pressing and fixing structure 3. Then, the operator aligns the wing with the installation position of the fuselage and bolts it in. During the connection process, since the fuselage is precisely fixed, there will be no displacement, which ensures that the connection accuracy and angle between the wing and the fuselage meet the design standards. After all the bolts between the wing and the fuselage are installed and reach the specified tightness, the cylinder 10 is activated. At this time, the piston rod of the cylinder 10 retracts, causing the mounting plate 11, Z-shaped plate 12, mounting rod 14, arc plate 17 and second arc-shaped rubber pad 18 to move upward, so that the second arc-shaped rubber pad 18 is detached from the top of the fuselage. Finally, the assembled drone can be removed from the support column 7 of the positioning support frame 2.

[0023] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
