Description

Technical Field

[0001] This utility model belongs to the field of testing and inspection equipment technology, and more specifically, it relates to a tooling frame for adjusting the center of gravity of a drone. Background Technology

[0002] With the rapid development of drone technology and the continuous expansion of its application fields, drone performance optimization has become increasingly important. Among these factors, the location of the drone's center of mass (CSM) has a crucial impact on flight stability, handling performance, and endurance. Therefore, accurate CSM adjustment has become an indispensable task in the design, manufacturing, and maintenance of drones.

[0003] Traditional methods for adjusting the center of gravity of drones typically rely on manual operation, such as suspension methods. While these methods are simple and easy to implement, they suffer from low precision and inefficiency, especially when dealing with large or heavy drones, where they are difficult to operate and pose safety risks. Furthermore, traditional methods often require multiple trials to achieve the desired adjustment effect, which is time-consuming and labor-intensive, failing to meet the demands of modern drone manufacturing for efficient and precise center of gravity adjustment.

[0004] In existing technologies, installing boosters on drones often requires frequent adjustments, which not only consumes the physical strength of operators but also poses various safety hazards such as collisions to the drone. Currently used center-of-gravity adjustment fixtures consist of only a single frame, which is not only difficult to manufacture but also time-consuming and labor-intensive when adjusting the drone. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a tooling frame for adjusting the center of gravity of a drone.

[0006] To achieve the above objectives, this utility model employs the following technical solution:

[0007] A UAV center-of-gravity adjustment fixture includes a frame, on which a rotating frame for placing the UAV is provided, a rotating mechanism rotatably connected to the rotating frame, and a support rod movably placed on the upper end of the frame. One end of the rotating frame is movably placed on the support rod. The rotating mechanism includes a rotating shaft and a rotating shaft connector sleeved on the rotating shaft. The rotating shaft is fixedly connected to the rotating frame through the rotating shaft connector, and both ends of the rotating shaft are rotatably connected to the frame through mounting seats.

[0008] Preferably, the frame has two parallel rear supports on one side, and the mounting base is installed between the two rear supports.

[0009] Preferably, a baffle is provided at the end of the rotating shaft, and the baffle contacts the mounting base.

[0010] Preferably, a U-shaped frame is provided at the bottom of the rotating frame, and the rotating shaft is fixedly connected to the U-shaped frame on the rotating frame through a rotating shaft connector.

[0011] Preferably, the frame is a frame structure made of U-shaped channel steel.

[0012] Preferably, the support rod is a U-shaped channel steel structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By setting up a rotating frame and a rotation mechanism, the UAV can remain stable during the adjustment process, ensuring the accuracy of the center of gravity adjustment operation. In particular, one end of the rotating frame is movably placed on the support rod, and the rotating shaft is fixedly connected to the rotating frame through the rotating shaft connector, which can effectively avoid the deviation caused by external force, thereby ensuring high precision in the center of gravity adjustment process.

[0015] 2. The frame adopts a U-shaped channel steel frame structure, and the support rods are also U-shaped channel steel structures. This not only improves the structural strength of the entire tooling frame, but also increases its load-bearing capacity, ensuring good stability and safety when performing center of gravity adjustment operations, even when facing drones of different sizes and weights. At the same time, when the support rods are removed, the rotating frame automatically resets and falls under gravity, which facilitates subsequent adjustments.

[0016] 3. A baffle is provided at the end of the rotating shaft, which contacts the mounting base. This not only prevents axial displacement of the rotating shaft during rotation, simplifying equipment maintenance, but also makes the connection between the rotating shaft and the rotating frame more stable due to the U-shaped frame design at the bottom of the rotating frame. It also facilitates the disassembly and installation of the rotating frame, improving the ease of operation of the equipment.

[0017] 4. The two parallel rear supports on one side of the frame, and the mounting base installed between the two rear supports, enhance the stability of the entire device, reduce safety hazards caused by accidental collisions or improper operation, and ensure the personal safety of operators.

[0018] In summary, the frame of this utility model is constructed from formed channel steel, and protective measures are formed by welding the channel steel, which facilitates processing, shortens the processing cycle, and reduces costs, thus avoiding injury to personnel and the drone during the center of gravity adjustment process. It can be adapted to drone transport trolleys for easy adjustment and saves manpower, allowing a single person to complete the drone's center of gravity adjustment work. In addition, the prototype of this utility model has been verified and used in suicide drones, proving its reliability and ease of use, and effectively improving assembly and debugging efficiency.

[0025] The present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings.

[0026] Example 1:

[0027] like Figure 1-3 As shown, a UAV center-of-gravity adjustment fixture includes a frame 3. The frame 3 is equipped with a rotating frame 2 for placing the UAV 9, a rotating mechanism rotatably connected to the rotating frame 2, and a support rod 1 movably placed on the upper end of the frame 3. One end of the rotating frame 2 is movably placed on the support rod 1. The rotating mechanism includes a rotating shaft 5 and a rotating shaft connector 4 sleeved on the rotating shaft 5. The rotating shaft 5 is fixedly connected to the rotating frame 2 via the rotating shaft connector 4, and both ends of the rotating shaft 5 are rotatably connected to the frame 3 via mounting seats 8. Specifically, the two rotating shaft connectors 4 ensure stable rotation of the rotating frame 2; the support rod 1 is movably placed on the upper end of the frame 3 to provide support for the rotating frame 2; the rotating shaft 5 is fixedly connected to the rotating frame 2 via the rotating shaft connector 4, and both ends of the rotating shaft 5 are rotatably connected to the frame 3 via the mounting seats 8, ensuring that the rotating frame 2 can rotate flexibly to adapt to different angle adjustment requirements.

[0028] Example 2:

[0029] A UAV center-of-gravity adjustment fixture differs from Embodiment 1 in that two parallel rear supports 7 are provided on one side of the frame 3, and a mounting base 8 is installed between the two rear supports 7. Specifically, the rear supports 7 are located on one side of the frame 3 to install the mounting base 8, thereby increasing the stability of the overall structure.

[0030] Furthermore, a baffle 6 is provided at the end of the rotating shaft 5. The baffle 6 contacts the mounting base 8. The baffle 6 is used to prevent the rotating shaft 5 from undergoing axial displacement during rotation, thus ensuring the reliability of the rotating mechanism.

[0031] Furthermore, a U-shaped frame 13 is provided at the bottom of the rotating frame 2, and the rotating shaft 5 is fixedly connected to the U-shaped frame 13 on the rotating frame 2 through the rotating shaft connector 4.

[0032] Furthermore, the frame 3 is a frame structure made of U-shaped channel steel. As the basic support structure of the entire tooling frame, the frame 3 adopts a frame structure made of U-shaped channel steel, which has high strength and stability.

[0033] Furthermore, the support rod 1 is a U-shaped channel steel structure, which increases its load-bearing capacity and ensures good stability and safety even when facing drones 9 of different sizes and weights during the center-of-gravity adjustment operation.

[0034] The working principle of this utility model is as follows:

[0035] In use, the drone 9 needs to be placed inside the rotating frame 2, and a steel wire rope needs to be threaded through the inside of the booster 10 and fixed at the connection point between the booster 10 and the drone 9. Figure 4-5 As shown, the unsecured support rod 1 is removed, allowing the rotating frame 2 to slowly fall. A level 12 is suspended at suspension point 11. By using the level 12 placed at the tail end of the booster 10, if the booster 10 is not vertical after being lifted, the angle of the booster 10 and the center of gravity of the drone 9 are continuously adjusted to ensure that the booster 10 remains vertical on the ground after being lifted. This ensures that the booster 10 applies stable thrust to the center of gravity during operation. Its structural principle is simple, facilitating drone assembly, effectively improving assembly efficiency, and saving manpower.
