A drone flipping tool

Abstract

This utility model discloses a drone flipping fixture, including a lifting assembly, a rotating frame, and a locking mechanism. The drone and rotating frame are lifted using a hoisting method, allowing the rotating shaft to fall into a bearing seat, thus assembling the rotating frame and lifting assembly. At this point, one or two personnel hold the operating handle and flip the rotating frame and the drone on it, bringing the drone to a predetermined angle that meets the requirements of subsequent processes. The locking mechanism then restricts the rotating frame, maintaining its angle, allowing for the removal of personnel to proceed with subsequent processes. During this process, because the operating handle is located at the far end of the rotating frame relative to the rotating shaft, it has a lever function, and the main weight of the drone is borne by the lifting assembly and bearing seat. Therefore, a small amount of manpower is required to maintain the angle between the drone and the rotating frame, thus solving the technical problem of high manpower requirements and time-consuming operations when performing large-angle flipping operations on medium and large-sized flying-wing drones.

Description

Technical Field

[0001] This utility model relates to the field of auxiliary devices for processing and assembling unmanned aerial vehicles (UAVs), specifically to a UAV flipping fixture. Background Technology

[0002] In the aerospace field, for medium to large flying-wing UAVs weighing between 100kg and 1000kg, a specific angle flipping operation is required during the preparation stage before hoisting the center of gravity.

[0003] In the prior art, there exists a device located on a platform carrying a drone, which uses a driving lifting component to lift one side of the drone to achieve a flip. However, this structure can only achieve a flip of no more than 90 degrees, and in certain processes required by certain drone models, a flip of less than 90 degrees cannot meet the requirements of the procedures and processes.

[0004] To perform large-angle flips exceeding 90 degrees on medium to large-sized flying-wing drones, current technology typically requires a significant amount of human intervention. For example, drones weighing several hundred kilograms often require dozens of people to operate in coordination, which is not only time-consuming and labor-intensive but also poses significant safety hazards.

[0005] Therefore, there is an urgent need in current technology for a flipping tooling device that can efficiently achieve large-angle flipping operations for medium and large flying-wing UAVs while reducing manpower input. Utility Model Content

[0006] To address the technical problems identified in the background section of the prior art, this utility model provides a drone flipping fixture. The technical problem to be solved by this utility model is achieved through the following technical solution:

[0007] A drone flipping fixture, comprising:

[0008] The lifting assembly includes a fixed frame, a linear drive mechanism mounted on the fixed frame, and at least two semi-open bearing seats. The linear drive mechanism has a moving part capable of reciprocating in the vertical direction. Each bearing seat is fixedly connected to the moving part, and each bearing seat is located at the same horizontal height with its opening facing upward.

[0009] The rotating frame includes a horizontal rotating shaft, a frame, an operating handle, and a fixing mechanism. The rotating shaft is placed in a bearing seat and is fixedly connected to one end of the frame. The operating handle is fixedly connected to the other end of the frame. The fixing mechanism is set on the frame and located between the operating handle and the rotating shaft. The fixing mechanism is used to fix the drone.

[0010] A locking mechanism is provided on the fixed frame. The locking mechanism can contact the rotating frame to limit the rotating frame from continuing to rotate and keep the rotating frame at a specific angle.

[0011] Furthermore, the rotating frame has an assembly position and a flip position. When the rotating frame is in the assembly position, the frame is horizontal and the drone is located below the frame and the bearing seat. The rotating frame can rotate to the flip position by rotating around the rotating shaft and passing below the bearing seat. At this time, the drone is located above the frame and the bearing seat. The locking mechanism can contact the rotating frame in the flip position to limit the rotating frame from continuing to rotate and keep the rotating frame in the flip position.

[0012] Furthermore, the fixing mechanism includes a clamp, which is located on the side of the frame facing the drone, with the opening of the clamp facing away from the frame, and is used to clamp and fix the drone.

[0013] Furthermore, the rotating frame also includes: multiple support columns, one end of which is detachably connected to the rotating shaft and / or the side of the frame facing the drone, and the side of the drone facing the frame has mounting holes corresponding to each support column, the other end of which is detachably connected to its corresponding mounting hole, and the length of each support column is configured to maintain the distance between the drone surface and the frame.

[0014] Furthermore, the lifting assembly includes: a horizontal beam parallel to the rotation axis, and multiple bearing seats fixedly connected to the beam and symmetrically distributed about the midpoint of the beam;

[0015] There are two linear drive mechanisms. The moving parts of the two linear drive mechanisms are at the same horizontal height. Each end of the crossbeam corresponds to a linear drive mechanism, and the two ends of the crossbeam are connected to the moving parts of their respective linear drive mechanisms.

[0016] Alternatively, a linear drive mechanism may have two moving parts at the same horizontal level, with one moving part connected to each end of the crossbeam along its length.

[0017] Furthermore, the linear drive mechanism has two components, and the lifting assembly also includes two vertical beams, with one vertical beam fixedly connected to each end of the horizontal beam along its length, and each of the two vertical beams connected to a moving part.

[0018] The fixed frame includes a bottom frame and two sleeves, one sleeve corresponding to a vertical beam. The vertical beam is slidably sleeved in its corresponding sleeve. The sleeve is fixedly connected to the bottom frame. A linear drive mechanism is set on the bottom frame, and a locking mechanism is set on the bottom frame.

[0019] Furthermore, the lifting assembly also includes a first locking element, which is disposed between the sleeve and the vertical beam to lock the relative position between the two.

[0020] Furthermore, the locking mechanism includes:

[0021] The diagonal support rod is fixedly connected between the bottom frame and the sleeve, and is located on the side of the rotating frame's movement path;

[0022] The stop lever is hinged to the inclined support rod. The stop lever has a retracted position and a blocking position. When the stop lever is in the retracted position, the stop lever is parallel to the inclined support rod. The stop lever can rotate around the hinge to reach the blocking position. At this time, the stop lever is on the movement path of the rotating frame. When the stop lever is in the blocking position, the stop lever can contact the operating handle to limit the rotation of the rotating frame.

[0023] The limiting component is fixedly connected to the inclined support rod, and the limiting component can restrict the stop bar to the blocking position;

[0024] The second locking element is located between the stop lever and the inclined support rod, and is used to lock the stop lever in the retracted position.

[0025] Furthermore, the bottom frame is equipped with multiple swivel casters, and a third locking element is provided between the swivel casters and the bottom frame to lock the swivel casters so that they cannot rotate.

[0026] Furthermore, a lifting ring is provided on the rotating shaft, and when the rotating frame is in the assembly position, the lifting ring is located above the rotating shaft.

[0027] The beneficial effects of this invention are as follows: Unlike existing technologies that involve lifting the drone from one side of a platform to rotate it while maintaining the angle between the rotating frame and the drone manually, this invention achieves a larger angle of rotation through height adjustment, hoisting, and rotation. Because the operating handle is located at the far end of the rotating frame relative to the rotation axis, it functions as a lever. Furthermore, the main weight of the drone is supported by the lifting assembly and bearing housing. Therefore, a small amount of manual labor is sufficient to maintain the angle between the drone and the rotating frame. After the rotation is complete, a locking mechanism stabilizes the angle, eliminating the need for manual labor and allowing for subsequent processes. This achieves the technical effect of efficiently performing large-angle rotation operations on medium and large-sized flying-wing drones while reducing manpower input, solving the technical problems of high manpower requirements and time-consuming labor in performing large-angle rotation operations on medium and large-sized flying-wing drones.

[0035] The present invention will be further described in detail below with reference to specific embodiments, but the implementation of the present invention is not limited thereto.

[0036] This utility model provides a drone flipping fixture, including: a lifting assembly, a rotating frame 3, and a locking mechanism. The lifting assembly includes a fixed frame 1, a linear drive mechanism 5 disposed on the fixed frame 1, and at least two semi-open bearing seats 24. The linear drive mechanism 5 has a moving part capable of reciprocating in the vertical direction. Each bearing seat 24 is fixedly connected to the moving part, and each bearing seat 24 is located at the same horizontal height with its opening facing upward. The rotating frame 3 includes a horizontal rotating shaft 32, a frame 31, an operating handle, and a fixing mechanism. The rotating shaft 32 is placed in the bearing seats 24 and is fixedly connected to one end of the frame 31. The operating handle is fixedly connected to the other end of the frame 31. The fixing mechanism is disposed on the frame 31 and located between the operating handle and the rotating shaft 32. The fixing mechanism is used to fix the drone. The locking mechanism is disposed on the fixed frame 1 and can contact the rotating frame 3 to limit the rotating frame 3 from continuing to rotate, so that the rotating frame 3 is held at a specific angle.

[0037] Please refer to Figure 1 and Figure 2In use, the rotating frame 3 is first connected to the drone via a fixing mechanism. The height of the bearing seat 24 is adjusted using the linear drive mechanism 5 of the lifting assembly. External conveying equipment, such as a trolley, conveyor belt, or lifting arm, is used to transport the drone and rotating frame to the area below the bearing seat. Then, the drone and rotating frame are lifted using a hoisting method, allowing the rotating shaft 32 to fall into the bearing seat 24, thus assembling the rotating frame 3 with the lifting assembly. At this point, one or two personnel hold the operating handle and use the linear drive mechanism 5 to raise the bearing seat 24, rotating frame 3, and drone, ensuring sufficient space for the rotating frame and drone to rotate. Then, personnel hold the operating handle to rotate the rotating frame 3 and the drone on it, allowing the drone to reach the predetermined angle required for subsequent processes. Please refer to [reference needed]. Figure 3 Then, a locking mechanism is used to make it contact the rotating frame 3, thereby restricting the rotating frame 3 from continuing to rotate and keeping it at a specific angle, so that manpower can be withdrawn and subsequent processes can be carried out.

[0038] In the process of maintaining the angle between the rotating frame and the drone using manpower, unlike the existing technology that involves lifting the drone from one side on the platform carrying the drone for flipping, this method uses height adjustment, hoisting, and flipping to achieve a larger angle of flipping. Since the operating handle is located at the far end of the rotating frame 3 relative to the rotating axis 32, it has lever properties, and the main weight of the drone is supported by the lifting assembly and bearing seat, a small amount of manpower is needed to maintain the angle between the drone and the rotating frame. After the flip is completed, the locking mechanism stabilizes the angle between the drone and the rotating frame 3, eliminating the need for manpower and allowing for subsequent processes. This achieves the technical effect of efficiently performing large-angle flipping operations on medium and large flying-wing drones while reducing manpower input, solving the technical problem of high manpower requirements and time-consuming and labor-intensive processes when performing large-angle flipping operations on medium and large flying-wing drones.

[0039] The above description only relates to one embodiment of the flipping method. In other embodiments, it is also applicable to other possible flipping methods required by the process. For example, if the initial angle of the drone is vertical or tilted, it can be flipped to a horizontal or tilted state at another angle, as long as the rotating shaft 32 falls into the bearing seat 24 from above. The bearing seat 24 and the lifting mechanism can still bear the weight of the drone and adjust its height. At the same time, with the setting of the rotating frame 3, the operating handle and the locking mechanism, the technical effect of flipping the drone at a large angle with effort and maintaining a specific angle can still be achieved.

[0040] In this embodiment, the linear drive mechanism uses an electric lifting rod suitable for lifting motion. Its moving part is a vertical electric push rod, and its power component is an electric cylinder, which can effectively achieve the lifting motion of large-load objects. In other embodiments, various common linear drive mechanisms suitable for lifting large-load objects can also be used, such as hydraulic drives, cylinders, transmission belts / chains, and pulley systems.

[0041] In various embodiments, the bearing housing 24 is a semi-open bearing housing with an opening at the top. The cross-section of the inner cavity of the bearing housing 24 in the vertical plane is V-shaped, U-shaped, or other cross-sectional shape that can be conceived by those skilled in the art to support the rotating shaft 32.

[0042] In some embodiments, a bushing 33 is also sleeved on the outside of the rotating shaft 32, and the bushing 33 is located between the rotating shaft and the bearing housing 24.

[0043] Further, please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 Considering that the flipping process generally occurs before or after the installation of the propulsion mechanism and the hoisting and calibration of the center of gravity of the UAV, in order to better and more conveniently adapt to this process setting, the rotating frame 3 specifically has an assembly position and a flipping position. When the rotating frame 3 is in the assembly position, please refer to... Figure 2 and Figure 4 The frame 31 is in a horizontal position. The drone and the rotating frame 3 are moved to the area below the frame 31 and the bearing housing 24 via a horizontally moving conveyor such as a trolley or conveyor belt. The rotating frame 3 is then hoisted into the bearing housing 24, causing it to rotate about the rotating shaft 32 and pass under the bearing housing 24, thus rotating to the flipped position. Please refer to [reference needed]. Figure 3 and Figure 5At this point, the angle between the drone and the rotating frame meets the requirements for installing the propulsion mechanism (this angle requirement is determined by the specific process of installing the propulsion mechanism; a common method is to hoist the propulsion mechanism from the upper gantry crane to the corresponding installation position of the drone, thus creating the angle requirement for the drone). The drone is positioned above the frame 31 and the bearing seat 24. By setting the position of the locking mechanism, it is possible to contact the rotating frame 3 in the flipped position, thus restricting the rotating frame 3 from continuing to rotate and keeping it in the flipped position that meets the angle requirements for assembling the propulsion mechanism. The propulsion mechanism can then be installed. After installation, a center of gravity calibration process is performed. The locking mechanism is released, and the drone and rotating frame are lifted using hoisting equipment, allowing the rotating shaft 32 to disengage from the upper opening of the bearing seat 24. The fixing mechanism is released, and the rotating frame 3 is removed, allowing the external hoisting equipment to lift only the drone, thus achieving the center of gravity calibration process. After completion, the rotating frame 3 and drone are reassembled using the fixing mechanism, and the rotating shaft 32 is placed back into the bearing seat 24 using external hoisting equipment. The rotating frame 3 is then flipped back to its assembly position, facilitating the removal of the drone and its transfer to subsequent processes.

[0044] In this embodiment, in order to achieve a stable angle locking effect by using a longer lever arm, the operating handle at the far end of the rotating frame 3 is in contact with the locking mechanism.

[0045] Furthermore, based on the common structural characteristics of medium and large-sized flying wing UAVs, the fixing mechanism needs to be specially designed. Specifically, the fixing mechanism includes: clamp 7, which is set on the side of the frame 31 facing the UAV, and the opening direction of the clamp 7 is away from the frame 31. The clamp 7 is used to clamp and fix the UAV.

[0046] The center of gravity of medium to large-sized flying-wing UAVs is usually located near the front of the fuselage, in front of the wings. Therefore, the roughly cylindrical fuselage needs to be the main area for fixation. For this structure, it is also necessary to meet the requirements of large-angle flipping and stability after flipping. Therefore, the best fixation method is to surround the cylindrical body. Thus, in this embodiment, a clamp 7 is selected as the main part of the fixation mechanism. In this embodiment, the clamp 7 is a common type with two movable arms, and a wing screw 8 between the two movable arms for locking the two movable arms. The inner side of the clamp 7 has a buffer layer.

[0047] Furthermore, since medium and large-sized flying wing UAVs are quite heavy, and the clamp 7 is a ring-shaped fixation for the columnar fuselage, the clamp 7 cannot effectively restrict the coaxial rotation tendency of the columnar fuselage during movement. The frictional damping generated by clamping may fail when facing a heavy fuselage.

[0048] Therefore, in order to better ensure the technical effect of large-scale flying wing UAVs with large-angle rotation, additional auxiliary fixing structures are required. Specifically, the rotating frame 3 also includes: multiple support columns 35, one end of which is detachably connected to the rotating shaft 32 and / or the side of the frame 31 facing the UAV. The side of the UAV facing the frame 31 has mounting holes corresponding to each support column 35, and the other end of the support column 35 is detachably connected to its corresponding mounting hole.

[0049] By opening multiple mounting holes on the surface of the drone and connecting them to the rotating shaft 32 and / or the frame 31 via support columns 35, the fixing effect of the clamp 7 can be effectively compensated, preventing the fuselage from rotating coaxially within the clamp 7. Since the mounting holes are opened on the surface of the drone, and the curved surface of the drone results in different distances between various points on its surface and the rotating shaft 32 and / or the frame 31, the length of each support column 35 needs to be specifically set to compensate for the gap between the rotating frame 3 and the drone. It can be replaced according to the unevenness of the fuselage surface of different models.

[0050] In this embodiment, the support column 35 is a hollow aluminum column, through which fixing bolts 34 are inserted, and both ends of the bolts are connected to the rotating shaft 32 and / or the frame 31 and the drone, respectively, thereby realizing a detachable connection between the support column 35 and the drone and the rotating shaft 32 and / or the frame 31. In other embodiments, common techniques suitable for detachable connections of heavy objects, such as snap-fit ​​connections or the use of limiting pins with limiting blocks and limiting holes, can also be adopted.

[0051] Furthermore, the lifting assembly includes: a horizontal beam 21, which is parallel to the rotating shaft 32; multiple bearing seats 24 are fixedly connected to the beam 21 and are symmetrically distributed around the midpoint of the beam 21; there are two linear drive mechanisms 5, the moving parts of the two linear drive mechanisms 5 are at the same horizontal height, each end of the beam 21 in the length direction corresponds to a linear drive mechanism 5, and each end of the beam 21 in the length direction is connected to the moving part of its corresponding linear drive mechanism 5; or the linear drive mechanism 5 has two moving parts at the same horizontal height, and each end of the beam 21 in the length direction is connected to a moving part.

[0052] Given the relatively heavy weight of the UAV but its centrally symmetrical characteristics, a horizontal beam is used as the connecting component of the bearing housing 24, and multiple bearing housings 24 are distributed in a centrally symmetrical manner. At the same time, two linear drive mechanisms 5 or two linear drive mechanisms 5 of the moving parts are used to drive both ends of the beam, so that the force on the beam 21 during movement is symmetrical and balanced, avoiding the problem of excessive stress concentration or offset to one side on the beam as much as possible.

[0053] Furthermore, a configuration of two linear drive mechanisms 5 was chosen. Two linear drive mechanisms 5 provide a higher upper limit for processing power, better suited to the weight characteristics of medium and large-sized flying-wing UAVs. The lifting assembly also includes: two vertical beams 22, with one vertical beam 22 fixedly connected to each end of the crossbeam 21 along its length, and each vertical beam 22 connected to a moving part; the fixed frame 1 includes a bottom frame and two sleeves 12, each sleeve 12 corresponding to one vertical beam 22, with the vertical beam 22 slidably fitted into its corresponding sleeve 12. The sleeve 12 is fixedly connected to the bottom frame. The linear drive mechanism 5 is mounted on the bottom frame, and a locking mechanism is also mounted on the bottom frame. The sleeve 12 provides guidance for the vertical beam 22's vertical movement, ensuring the linearity of the movement of the vertical beam 22 and crossbeam 21, guaranteeing the stability of the lifting motion, and preventing tilting under heavy loads from affecting or damaging the linear motion mechanism 5.

[0054] Furthermore, when the drone and the rotating frame 3 move to a certain height and maintain that height, in order to prevent the weight of the excessively large drone from being entirely transferred to the linear motion mechanism 5 and thus damaging it, the lifting assembly also includes a first locking member 6. The first locking member 6 is disposed between the sleeve 12 and the vertical beam 22 to lock the relative position between the two. This makes the sleeve 12, the vertical beam 22, and the first locking member 6 the main weight-bearing structures.

[0055] In this embodiment, the first locking element 6 is in the form of a limiting pin. Corresponding limiting holes are provided on the vertical beam 22 and the sleeve 12. By simultaneously inserting the limiting pin into the limiting holes on both the vertical beam 22 and the sleeve 12, the sleeve 12 and the vertical beam 22 can be locked. The cross-sections of the limiting holes and the limiting pin can be rectangular, square, or circular, etc. In other embodiments, other common types of locking structures can also be used, such as a snap-fit ​​structure between the vertical beam 22 and the sleeve 12, a fastening clamp on the sleeve 12 for clamping and securing the vertical beam 22, or a fastening bolt, etc.

[0056] In this embodiment, the corners where the crossbeam 21 connects to the vertical beam 22 are reinforced by reinforcing ribs 23. An electric cylinder upper connecting lug 26 is provided above the vertical beam 22, which is connected to the moving part of the linear drive mechanism 5 of the electric cylinder type. Two upper mounting plates 25 are symmetrically arranged below the middle of the crossbeam 21, and the upper mounting plates 25 are connected to the bearing seat 24.

[0057] Furthermore, the locking mechanism includes: a diagonal support rod 14, fixedly connected between the bottom frame and the sleeve 12, and located beside the movement path of the rotating frame 3; a stop rod 17, hinged to the diagonal support rod 14, the stop rod 17 having a retracted position and a blocking position. When the stop rod 17 is in the retracted position, the stop rod 17 is parallel to the diagonal support rod 14, and the stop rod 17 can rotate around the hinge to reach the blocking position. At this time, the stop rod 17 is located on the movement path of the rotating frame 3. When the stop rod 17 is in the blocking position, the stop rod 17 can contact the operating handle to limit the rotation of the rotating frame 3; a limiting member, fixedly connected to the diagonal support rod 14, the limiting member can limit the stop rod 17 to the blocking position; and a second locking member 9, disposed between the stop rod 17 and the diagonal support rod 14, used to lock the stop rod 17 in the retracted position.

[0058] In this embodiment, the bottom frame includes: a fixed longitudinal beam 11, a bottom crossbeam 13, a lower connecting lug 18 for the electric cylinder, and a bottom connecting plate 19. The limiting components include a starting lug 15 and an ending lug 16. A sleeve 12 is positioned in the middle of the fixed longitudinal beam 11, forming an inverted T-shape. Slanted support rods 14 are provided before and after the sleeve 12. A movable stop rod 17 is positioned on the rear slanted support rod 14. The stop rod 17 has a starting lug 15 and an ending lug 16 at its starting point, thus limiting the rotation of the stop rod 17. When the stop rod 17 is in the blocking position, the ending lug 16 supports and limits the stop rod 17 from bottom to top. The two fixed longitudinal beams 11 are connected as one unit via the bottom crossbeam 13. The lower connecting lug 18 for the electric cylinder is connected to the body of the linear drive mechanism 5. The bottom connecting plate 19 strengthens the fixing relationship between the longitudinal beam 11 and the bottom crossbeam 13.

[0059] In this embodiment, the second locking member 9 is in the form of a pin. Pin holes are provided at the corresponding positions of the inclined support rod 14 and the stop rod 17. The pin can be inserted into the pin holes of the inclined support rod 14 and the stop rod 17 at the same time, thereby locking the stop rod 17 in the storage position.

[0060] Furthermore, multiple swivel casters 4 are provided on the bottom frame, and a third locking element is provided between the swivel casters 4 and the bottom frame to lock the swivel casters 4 so that they cannot rotate. Considering the location of various conveying and hoisting equipment in the production and testing plant, swivel casters 4 are required to facilitate handling and movement, and to maintain stability when tilted. Therefore, a third locking element is provided to lock the swivel casters 4.

[0061] Furthermore, a lifting ring 36 is provided on the rotating shaft 32, and when the rotating frame 3 is in the assembly position, the lifting ring 36 is located above the rotating shaft 32.

[0062] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
