Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and more specifically to a device and method for processing a wing of an unmanned aerial vehicle. Background Art

[0002] A drone is an unmanned aircraft, usually powered by batteries; it can fly and perform missions according to pre-set routes or remote control. Drones can be used in a variety of different fields, such as military reconnaissance, aerial photography, cargo transportation, etc. The design and functions of drones can be adjusted and improved according to different needs.

[0003] In order to obtain good flight stability and flight performance, drones currently often have their wings modified. The current wing processing mainly includes stamping or injection molding, followed by trimming and polishing to ensure the normal use of drone wings.

For example, the edge of the drone wing is often curved, and the above equipment cannot perform adaptive polishing on the curved edge of the drone wing. At the same time, there is a lack of fine finishing after grinding, resulting in the wing still needing subsequent polishing. Therefore, the present invention provides a drone wing processing device and method to solve the above problems. Summary of the invention

[0019] Preferably, the shape of the base is polygonal, and the number of grinding components is adjusted according to the number of times the wing needs to be processed and trimmed.

[0020] A processing method applicable to unmanned aerial vehicle wing processing equipment, the processing method comprising:

[0021] S1: First, place the stamped or injection-molded wing in the mounting hole and fix it with a clamping rod;

[0022] S2: Then according to the polishing process, different types of grinding stones are replaced in the sliding block, and the position of the sliding block is moved through the No. 1 slide slot so that the grinding stone on the sliding block is located at the lowest point of the end of the wing curve;

[0023] S3: By rotating the limit rod, the lower limit of movement of the sliding block is limited;

[0029] 3. The present invention can connect other support rods through the connecting holes, thereby expanding the number of wings installed at one time. Because a drone generally has four wings, by expanding the number of support rods, the device can simultaneously process four wings, thereby improving processing efficiency.

[0039] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0040] like Figure 1-7 As shown, the present invention provides a UAV wing processing device, comprising:

[0041] A base 1, a slide rail 11 is fixedly connected to the bottom of the base 1, a clamping seat 12 is slidably connected to the slide rail 11, a No. 1 motor 13 is fixedly connected to one side of the slide rail 11, and a threaded rod 14 for driving the clamping seat 12 to move is connected to the output end of the No. 1 motor 13;

[0042] The grinding assembly 2 is arranged on the clamping seat 12, and the grinding assembly 2 includes a support seat 21, and the support seat 21 is installed on the clamping seat 12. The upper end of the support seat 21 is fixedly connected to a fixing frame 22, and a driving electric rail 221 is arranged on one side of the upper end of the fixing frame 22. The telescopic rod 23 is slidably connected to the driving electric rail 221, and the end of the telescopic rod 23 away from the fixing frame 22 is fixedly connected to a fixing rod 24, and one side of the fixing rod 24 is provided. There is a No. 1 slide groove 241, in which a sliding block 242 is slidably connected, and a grindstone 2421 is installed in the sliding block 242; the sliding block 242 is connected to the grindstone 2421 by a headless screw, a triangular groove 2422 is provided inside the grindstone 2421, and an adjusting groove 2423 is provided on the inner wall of the triangular groove 2422, and a grindstone block 2424 is slidably connected inside the adjusting groove 2423, and a spring is provided between the grindstone block 2423 and the adjusting groove 2423;

[0043] The clamping assembly 3 includes a support rod 31, a second motor 32 for driving the support rod 31 to rotate is disposed at the bottom end of the support rod 31, a mounting hole 34 is provided on the support rod 31, a circular ring 341 is disposed in the mounting hole 34, and a clamping rod 342 is slidably connected in the circular ring 341.

[0044] A processing method applicable to unmanned aerial vehicle wing processing equipment, the processing method comprising:

[0045] S1: First, place the stamped or injection-molded wing in the mounting hole 34 and fix it by the clamping rod 342;

[0046] S2: Then according to the polishing process, different types of grinding stones are replaced in the sliding block 242, and the position of the sliding block 242 is moved through the first slide groove 241, so that the grinding stone 2421 on the sliding block 242 is located at the lowest point of the end of the wing curve;

[0047] S3: By rotating the limit rod 2431, the lower limit of movement of the sliding block 242 is limited;

[0048] S4: The telescopic rod 23 is extended and retracted to drive the grindstone 2421 on the sliding block 242 to grind the edge of the wing. Under the guidance of the curved edge of the wing, the sliding block moves up and down along the first slide groove 241;

[0049] S5: After the first grinding process is completed, the telescopic rod 23 drives the fixed rod 24 to move away from the wing, and then the second motor 32 drives the support rod 31 to rotate, so that the wing is transferred to another direction and fine grinding is continued. After one cycle, the processing and trimming of the wing edge is completed.

[0050] Embodiment 1:

[0051] like Figure 1-7 As shown, in this embodiment, taking the example that the wing needs to undergo five processing and trimming to complete the process from rough grinding to fine grinding of the wing edge, the base 1 is in the shape of a pentagon, and a slide rail 11, a clamping seat 12, a No. 1 motor 13 and a threaded rod 14 are installed on each edge. Then, the support seat 21 in the grinding assembly 2 is placed on the clamping seat 12, and the No. 1 motor 13 drives the threaded rod 14 to rotate, so that the clamping seat 12 clamps the support seat 21. Then the staff installs the wing in the mounting hole 34 in the clamping assembly 3, and clamps the wing through the clamping rod 342.

[0052] Then, according to the installation position of the wing, the telescopic rod 23 is controlled to start, so that the sliding block 242 on the fixed rod 24 is close to the edge of the wing. According to the size of the wing, the spacing between the fixed rods 24 can be adjusted by driving the electric rail 221 to adapt to wings of different sizes. After the sliding block 242 is in place, the staff slides the sliding block 242 in the first slide slot 241, such as Figure 8 As shown by the middle arrow, the grinding stone 2421 in the sliding block 242 is moved to the lowest point of the wing, and then the limiting rod 2431 in the No. 2 slide groove 23 is rotated so that the rubber block on the limiting rod 2431 is in close contact with the inner wall of the No. 2 slide groove 243, and the lowest point of the sliding block 242 is limited. After the PLC program is set, the position of the sliding block 242 does not need to be adjusted during the next grinding, and it can be directly moved to the lowest point of the wing (the same batch), thereby simplifying the processing flow.

[0053] When the grindstone 2421 contacts the lowest point of the wing edge, the telescopic rod 23 pulls the fixed rod 24 to move, so that the grindstone 2421 grinds the edge of the wing. After the grinding is completed, the second motor 32 drives the support rod 31 to rotate, so that the wing is transferred to the other side to complete the next processing action. Each step is the same. The difference is that the grindstone 2421 in the sliding block 242 is different, thereby completing the process from rough grinding to fine grinding of the wing, reducing the burrs on the edge of the wing, so that the wing meets the use requirements.

[0054] A triangular groove 2422 is provided inside the grindstone 2421 so that the triangular groove 2422 can better adapt to the edge of the wing when grinding the wing, and an adjusting groove 2423 is provided inside the triangular groove 2422, a grindstone block 2424 is slidably connected inside the adjusting groove 2423, and a spring is provided between the grindstone block 2424 and the adjusting groove 2423 so that the spring connects the grindstone block 2424 and the adjusting groove 2423; the grindstone block 2424 can slide inside the adjusting groove 2423 according to the thickness of the wing, so that the gap between the two grindstone blocks 2424 can adapt to the thickness of the wing and be adjusted, thereby improving the processing effect of the grindstone block 2424 on the wing.

[0055] It should be noted that: the sliding block 242 is slidably connected to the first slide groove 241. Under the guidance of the wing edge curve, the sliding block 242 can automatically slide up and down to complete the grinding of the wing edge. At the same time, two mounting holes 34 are provided on the support rod 31. Figure 2 As shown, the orientation of the mounting holes 34 is convenient for grinding both wings at the same time.

[0056] Embodiment 2:

[0057] like Figure 2 , 6 -7, the difference between this embodiment and the first embodiment is that, in this embodiment, an electromagnet 35 is arranged inside the support rod 31 and below the circular ring 341, a ball 36 is rollingly connected above the electromagnet 35 and outside the circular ring 341, an N pole body 3411 and an S pole body 3412 are arranged on the upper and lower sides of the circular ring 341, and a ratchet that can only allow the circular ring 341 to rotate in one direction is arranged at the connection between the circular ring 341 and the circular hole 34;

[0058] Because the wing remains in the same state during the processing, which may cause over-grinding on one side, the above design can realize the flipping of the wing, thereby preventing over-grinding on one side.

[0059] When the wing is polished once, the second motor 32 drives the support rod 31 to rotate, so that the wing is transferred to the next process for polishing. During the rotation of the support rod 31, the current direction of the electromagnet 35 changes, thereby generating the same polarity as the N pole 3411 or the S pole 3412 in the ring 341. Because the ring 341 is connected to the inside of the support rod 31 through the ball 36, the repulsive force generated by the electromagnet 35 pushes the ring 341 to rotate. At the same time, because a ratchet is provided at the connection between the ring 341 and the support rod 31, the ring 341 can only rotate in one direction, which promotes the efficiency of the rotation of the ring 341; when the pole on the other side of the ring 341 approaches the electromagnet 35, the pole is attracted and approaches the electromagnet 35, thereby realizing the flipping of the wing, making the wing processing range wider.

[0060] It should be noted that the N pole body 3411 and the S pole body 3412 occupy at least two-thirds of the volume of the ring 341, thereby ensuring that the ring 341 can rotate stably; at the same time, two electromagnets 35 can be set on the upper and lower sides of the ring 341, and the ratchet design can be eliminated. The rotation of the ring 341 is controlled by changing the polarity of the two electromagnets 35.

[0061] Embodiment three:

[0062] like Figure 5 As shown, in this embodiment, a connecting hole 33 is opened at the upper end of the support rod 31, and other support rods 31 can be connected through the connecting hole 33, thereby expanding the number of wings installed at one time. Because a UAV generally has four wings, by expanding the number of support rods 31, the device can simultaneously process four wings, thereby improving processing efficiency.

[0063] It should be noted that: after the number of support rods 31 is expanded, the heights of the wings are all different. The position of the limit rod 2431 in the second slide groove 243 can be adjusted, and then the height of the sliding block 242 can be adjusted to achieve the grinding of wings of different heights; the directions of the mounting holes 34 on the support rods 31 and the expanded support rods 31 correspond to the straight edges of the polygonal base 1, so that at the same time, four grinding components 2 can simultaneously process and grind four wings, greatly improving production efficiency.

[0064] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
