Description

Technical Field

[0001] This utility model relates to the field of testing robotic arms, and in particular to a drone testing robotic arm that can quickly change probes. Background Technology

[0002] In the research and development and production of drones, testing their circuit signals, sensor accuracy, and other performance aspects is a crucial step in ensuring product quality. A drone testing robotic arm with quick-change probes is a specialized device designed to meet the demands of efficient testing. This robotic arm needs to precisely connect with the probe assembly to the part of the drone being tested, transmitting test signals through the probes. Simultaneously, leveraging the drone's mobility, it can flexibly cover different locations and types of test points. It is widely used in batch testing on drone production lines and in fault diagnosis scenarios during after-sales maintenance, making it one of the core pieces of equipment for improving the efficiency and accuracy of drone testing.

[0003] Currently, most robotic arms used for drone testing employ bolt-fixed, threaded, or multi-set snap-fit ​​mechanical structures for probe connection. Technically, probe installation and replacement typically involve manually tightening or loosening the fasteners using screwdrivers, wrenches, or other tools. While some optimized designs utilize elastic snap-fit ​​designs, auxiliary tools are still needed to pry open the snap-fit ​​components to separate the probe from the robotic arm body. Overall, probe assembly and disassembly rely on multiple manual steps.

[0004] However, the existing methods for disassembling and assembling robotic probes have significant drawbacks. Because manual intervention with tools is required to tighten or loosen multiple sets of fasteners, the entire process is cumbersome and time-consuming. In batch testing scenarios for drones, when different probe models need to be frequently changed for different test items, the excessively long disassembly and assembly time significantly reduces the testing cycle, leading to a decrease in overall testing efficiency. Furthermore, the complex operating procedures can cause wear and tear on the probe or robotic arm connection points due to improper manual operation, further affecting the lifespan of the testing equipment and the stability of testing accuracy. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a drone testing robotic arm with quick probe replacement, aiming to improve the problem of cumbersome probe disassembly and assembly in existing drone robotic arms.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a drone testing robotic arm with quick probe replacement, comprising a top plate, a support rod fixedly connected to the bottom of the top plate, a propeller fixedly connected to the top of the support rod, a base plate fixedly connected to the bottom of the support rod, a locking block fixedly connected to the bottom of the base plate, a connecting plate fixedly connected to the bottom of the locking block, an operating arm fixedly connected to the bottom of the connecting plate, and a buckle assembly provided at one end of the operating arm; The buckle assembly includes a fixing block, the side wall of which is fixedly connected to one end of the operating arm. A hollow block is slidably connected inside the fixing block. A pin is fixedly connected to the side wall of the hollow block. A limit ring is slidably connected to the inner wall of the hollow block. A locking post is fixedly connected to the outer wall of the limit ring. A connecting post is slidably connected to the inner wall of the limit ring. A button is fixedly connected to one end of the connecting post. A fixing plate is fixedly connected to one end of the connecting post. A spring-loaded component is provided on the side wall of the fixing plate.

[0007] As a further description of the above technical solution: The rebound assembly includes a spring, with both ends of the spring fixedly connected to the side wall of the fixed disk.

[0008] As a further description of the above technical solution: The fixing block has a slot inside, and the outer wall of the limiting ring is slidably connected to the inner wall of the slot.

[0009] As a further description of the above technical solution: The hollow block has a groove on its inner wall, and the outer wall of the limiting ring is slidably connected to the inner wall of the groove.

[0010] As a further description of the above technical solution: An electric push rod is fixedly connected to the outer wall of the connecting plate, a connecting frame is fixedly connected to the output end of the electric push rod, and a fixing frame is fixedly connected to the top of the electric push rod.

[0011] As a further description of the above technical solution: The inner wall of the connecting frame is rotatably connected to a rotating shaft, and the outer wall of the rotating shaft is rotatably connected to a bearing.

[0012] As a further description of the above technical solution: The outer wall of the bearing is rotatably connected to the inner wall of the connecting frame, and the outer wall of the rotating shaft is rotatably connected to the inner wall of the fixed frame.

[0013] As a further description of the above technical solution: A rotating plate is rotatably connected to the outer wall of the rotating shaft, and a rotating shaft is rotatably connected inside the rotating plate.

[0014] As a further description of the above technical solution: The outer wall of the rotating shaft is rotatably connected to a clamping plate, and the bottom of the clamping plate is slidably connected to the top of the clamping block.

[0015] As a further description of the above technical solution: The card plate is rotatably connected to a rotating shaft three inside, and a fixing block is rotatably connected to the outer wall of the rotating shaft three.

[0016] This utility model has the following beneficial effects: 1. In this utility model, pressing the button drives the connecting column and the limiting ring to move. Next, the connecting column drives the fixing plate to compress the spring on the side wall. Then, the limiting ring drives the locking column to disengage its outer wall from the locking state of the fixing block. Then, the side wall of the hollow block can be disengaged from the inner wall of the fixing block, achieving the effect of quickly disassembling the ejector pin. This solves the problem of cumbersome disassembly and assembly of traditional robotic arm probes and improves the convenience of testing robotic arms for UAVs.

[0017] 2. In this utility model, the connecting frame is moved by an electric push rod, and then the connecting frame will drive the rotating plate to move. Subsequently, after the rotating plate is subjected to force, it will drive the clamping plate to rotate on the central axis of the rotating shaft three, and the top of the clamping plate will disengage from the top of the clamping block, thus achieving the effect of quick disassembly of the operating arm. This solves the problem of low disassembly efficiency when repairing and replacing robotic arm components, and improves the flexibility of maintenance of the drone testing robotic arm.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-3 This utility model provides an embodiment of a drone testing robotic arm with quick-change probes, including a top plate 1. The top plate 1 provides top fixed support for a support rod 2, thereby ensuring that the support rod 2 remains stable during drone flight and robotic arm operation, avoiding the impact of the support rod 2's swaying on the robotic arm's testing accuracy, and improving the overall structural stability. The support rod 2 is fixedly connected to the bottom of the top plate 1, and a propeller 4 is fixedly connected to the top of the support rod 2. The propeller 4 provides flight power for the drone, thereby driving the entire drone testing robotic arm device to move in the air, meeting the position adjustment requirements under different testing scenarios, and providing flexible spatial movement capability for probe testing operations. This is common knowledge and will not be elaborated further here. The bottom of the support rod 2 is fixedly connected to a bottom plate 3, and a locking block 5 is fixedly connected to the bottom of the bottom plate 3. A connecting plate 6 is fixedly connected to the bottom of the locking block 5, and an operating arm 7 is fixedly connected to the bottom of the connecting plate 6. A buckle assembly is provided at one end of the operating arm 7. The latching assembly includes a fixing block 15, whose side wall is fixedly connected to one end of the operating arm 7. A hollow block 16 is slidably connected inside the fixing block 15. A pin 18 is fixedly connected to the side wall of the hollow block 16. A limit ring 19 is slidably connected to the inner wall of the hollow block 16. The limit ring 19 moves in conjunction with the connecting post 21, simultaneously causing the locking post 24 to slide within the slide groove 17 and the locking slot 25, thereby achieving the engagement and disengagement of the locking post 24 and the locking slot 25, achieving the effect of controlling the fixing and disassembly of the pin 18. The outer wall of the limit ring 19 is fixedly connected to the locking post 24, and the inner wall of the limit ring 19 is slidably connected to... A connecting post 21 is connected to a button 20 fixedly connected to one end of the connecting post 21, and a fixed plate 22 fixedly connected to the other end of the connecting post 21. A spring-loaded assembly is provided on the side wall of the fixed plate 22. A spring 23 is used to provide elastic restoring force, so that it is compressed when the fixed plate 22 moves. After the external force is removed, the fixed plate 22 is pushed to reset, providing power for the reset of the connecting post 21, the limit ring 19 and the locking post 24, and ensuring the automatic reset of the ejector pin 18 during disassembly and assembly. This is common knowledge and will not be described in detail here. The spring-loaded assembly includes a spring 23, and the two ends of the spring 23 are respectively fixedly connected to the side wall of the fixed plate 22.

[0022] Reference Figure 4 and Figure 5The fixed block 15 has a slot 25 inside, and the outer wall of the limiting ring 19 is slidably connected to the inner wall of the slot 25. The inner wall of the hollow block 16 has a sliding groove 17, which provides a sliding path for the locking post 24, thereby ensuring that the locking post 24 can move smoothly in the hollow block 16, avoiding jamming when the locking post 24 moves, and ensuring the precise engagement and disengagement of the locking post 24 and the slot 25 during the assembly and disassembly of the ejector pin 18. The outer wall of the limiting ring 19 is slidably connected to the inner wall of the sliding groove 17. The outer wall of the connecting plate 6 is fixedly connected to an electric push rod 27. The output end of the electric push rod 27 is fixedly connected to a connecting frame 8. The top of the electric push rod 27 is fixedly connected to a fixed frame 26. The inner wall of the connecting frame 8 is rotatably connected to a rotating shaft 9. The outer wall of the rotating shaft 9 is rotatably connected to a bearing 10. The outer wall of the bearing 10 is rotatably connected to the inner wall of the connecting frame 8. The outer wall of the rotating shaft 9 is rotatably connected to... The rotating plate 11 is rotatably connected to the outer wall of the rotating shaft 9, which is attached to the inner wall of the fixed frame 26. The rotating plate 11, in conjunction with the rotating shaft 2 12, transmits force, thereby pulling the clamping plate 13 under the drive of the rotating shaft 9, thus achieving the effect of converting the rotational motion of the rotating shaft 9 into the rotational motion of the clamping plate 13. The rotating shaft 2 12 is rotatably connected inside the rotating plate 11, and the clamping plate 13 is rotatably connected to the outer wall of the rotating shaft 2 12. The clamping plate 13, in conjunction with the clamping block 5, performs locking and unlocking movements. Thus, under the action of the linkage structure driven by the electric push rod 27, the operating arm 7 and the connecting plate 6 are fixed and separated, achieving the effect of quickly completing the maintenance, disassembly and installation of the operating arm 7. The bottom of the clamping plate 13 is slidably connected to the top of the clamping block 5, and the rotating shaft 3 14 is rotatably connected inside the clamping plate 13. The outer wall of the rotating shaft 3 14 is rotatably connected to the fixed block 15.

[0023] Working principle: When testing the robotic arm using a drone, firstly, pressing button 20 moves the connecting column 21. Then, under pressure, the connecting column 21 moves the limiting ring 19. Next, as the limiting ring 19 moves, it moves the locking pin 24 on the outer wall, causing it to slide along the inner wall of the groove 17 inside the hollow block 16. Then, under pressure, the connecting column 21 moves the fixing plate 22 on the side wall. Next, as the fixing plate 22 moves, it compresses the spring 23 on the side wall. When the pin 24 is subjected to force, it will disengage from the inner wall of the fixing block 15, achieving the effect of quick disassembly of the ejector pin 18. Then, when installing the ejector pin 18, the hollow block 16 is aligned with the fixing block 15 and inserted. After releasing the button 20, the compressed spring 23 will push the connecting pin 21 to reset through the fixing plate 22. The limiting ring 19 will then drive the pin 24 to re-engage into the slot 25 of the fixing block 15, achieving quick fixation of the probe. The whole process does not require external tools, effectively shortening the probe disassembly and assembly time. During the maintenance and disassembly of the operating arm 7, rapid separation is achieved through a linkage structure driven by the electric push rod 27. Activating the electric push rod 27 causes its output end to push the connecting frame 8 to move. The connecting frame 8, through the bearing 10 on its inner wall, drives the rotating shaft 9 to rotate within the fixed frame 26. As the rotating shaft 9 rotates, it causes the rotating plate 11 on the outer wall to deflect around the rotating shaft 9. The rotating plate 11, through the rotating shaft 12, pulls the clamping plate 13, causing it to rotate around the rotating shaft 14. The bottom of the clamping plate 13 gradually disengages from the limiting structure at the top of the clamping block 5, releasing the fixed relationship between the operating arm 7 and the connecting plate 6, allowing the operating arm 7 to be removed for maintenance. When installing the operating arm 7, the electric push rod 27 is driven in the reverse direction. Through the coordinated linkage of the rotating shaft 9, rotating shaft 12, and rotating shaft 14, the clamping plate 13 is re-clamped onto the top of the clamping block 5, ensuring a stable connection between the operating arm 7 and the connecting plate 6 and improving maintenance flexibility.
