Description

Technical Field

[0001] This invention relates to the field of aircraft assembly technology, and in particular to an aircraft assembly jig tooling with a rotating structure and its operation method. Background Technology

[0002] In today's society, aircraft are becoming increasingly common and are being used in more and more places. Among them, the most common aircraft is the drone. However, the production process requires precise manufacturing and assembly. Because of its irregular shape, the assembly process is not easy and can cause some inconvenience. Therefore, in the actual production process, a kind of tooling is set up to assist workers in assembling the drone.

[0003] In existing technologies, assembly racks are often used as auxiliary assembly tables, where workers place the aircraft for assembly. However, existing assembly tables have the following problems: First, to avoid the assembly parts toolbox affecting the assembly work, it is often placed far from the assembly position, making it inconvenient to retrieve and place assembly parts; second, when the aircraft is assembled on one side and the position needs to be adjusted to assemble the other side, it is necessary to hold the aircraft by hand to adjust its position or move the operator to the next step of assembly, which is very inconvenient. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background art by proposing an aircraft assembly jig tooling with a rotating structure.

[0005] The technical solution of the present invention: A vehicle assembly jig tooling with a rotating structure includes an assembly table, an arc-shaped inner cavity on the assembly table, a vertical plate fixedly connected inside the arc-shaped inner cavity, two sliders slidably connected inside the arc-shaped inner cavity, a connecting block fixedly connected to the top of the sliders, a toolbox assembly fixedly connected to the top of the connecting block, a first spring fixedly connected between the sliders and the vertical plate, a pull rope fixedly connected to the side of the slider away from the first spring, the other end of the pull rope movably passing through the arc-shaped inner cavity and fixedly connected to a pull handle, a loading tray rotatably connected to the top of the assembly table, a rotating rod fixedly connected to the bottom of the loading tray, a foot-kick resistance assembly provided around the bottom end of the rotating rod, and the foot-kick resistance assembly is used to limit and fix the rotation of the rotating rod.

[0006] Preferably, the bottom of the assembly table is fixedly connected with multiple feet.

[0007] Preferably, the toolbox assembly includes a circular sliding disk fixedly connected to the top of the connecting block, a vertical rod fixedly connected to the top of the circular sliding disk, a plurality of equidistant fixed sleeves fixedly sleeved around the periphery of the vertical rod, and a storage box fixedly connected to the outer wall of the fixed sleeve.

[0008] Preferably, the top of the assembly table is provided with an arc-shaped groove, and the bottom of the circular sliding disk is slidably connected to the arc-shaped groove. An arc-shaped guide hole communicating with the arc-shaped inner cavity is provided on the arc-shaped groove, and the connecting block passes through the arc-shaped guide hole.

[0009] Preferably, the assembly table has a circular through hole in the middle, and the rotating rod passes through the circular through hole.

[0010] Preferably, the outer arc surface of the tray is fixedly connected to multiple levers.

[0011] Preferably, the kick-type resistance assembly includes a resistance box fixed to the ground, and a rotating rod is rotatably inserted into the inside of the resistance box. An arc-shaped resistance plate is slidably connected inside the resistance box. A second spring is fixedly connected between one side of the arc-shaped resistance plate and the inner wall of the resistance box. Two connecting rods are fixedly connected to the other side of the arc-shaped resistance plate. The ends of the two connecting rods away from the arc-shaped resistance plate move through the outer wall of the resistance box and are jointly fixedly connected to a kick plate.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] This practical device places the aircraft assembly parts in the carrying box and the aircraft to be assembled on the carrying tray. When parts need to be assembled, pulling the handle will bring the toolbox assembly closer for easy selection of the parts. Releasing the handle will cause the toolbox assembly to return to its initial position under the rebound force of the first spring, thus avoiding interference with the aircraft assembly. When the aircraft angle needs to be adjusted during assembly, kicking the kick plate will release the rotating rod of the arc-shaped drag plate, thereby restoring the rotation capability of the carrying tray. Then, the lever can be used to rotate the carrying tray and the aircraft above it to the appropriate angle for continued assembly, eliminating the need for manual adjustment of the aircraft position and making it more convenient to use.

[0018] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] like Figure 1-3 As shown, the present invention proposes an aircraft assembly jig tooling with a rotating structure, including an assembly table 1. The assembly table 1 has an arc-shaped inner cavity 3. A vertical plate 4 is fixedly connected inside the arc-shaped inner cavity 3. Two sliders 6 are slidably connected inside the arc-shaped inner cavity 3. A connecting block 7 is fixedly connected to the top of the sliders 6. A toolbox assembly is fixedly connected to the top of the connecting block 7. A first spring 5 is fixedly connected between the sliders 6 and the vertical plate 4. A pull rope 8 is fixedly connected to the side of the slider 6 away from the first spring 5. The other end of the pull rope 8 movably passes through the arc-shaped inner cavity 3 and is fixedly connected to a pull handle 9. A loading tray 10 is rotatably connected to the top of the assembly table 1.

[0021] In this embodiment: the bottom of the assembly table 1 is fixedly connected with multiple feet 2; the toolbox assembly includes a circular sliding disk 21 fixedly connected to the top of the connecting block 7, a vertical rod 12 fixedly connected to the top of the circular sliding disk 21, a plurality of equidistant fixed sleeves 13 fixedly sleeved around the periphery of the vertical rod 12, and a storage box 14 fixedly connected to the outer wall of the fixed sleeve 13; the top of the assembly table 1 is provided with an arc-shaped groove, and the bottom of the circular sliding disk 21 is slidably connected to the arc-shaped groove, and an arc-shaped guide hole communicating with the arc-shaped inner cavity 3 is provided on the arc-shaped groove, and the connecting block 7 passes through the arc-shaped guide hole.

[0022] Working principle: This device first places the aircraft assembly parts in the storage box 14, and then places the aircraft to be assembled on the storage tray 10. When parts need to be assembled, pulling the handle 9, connected by the pull rope 8 and the connecting block 7, pulls the toolbox assembly closer, making it easier to select the assembly parts from the storage box 14. At this time, the first spring 5 is stretched. After selecting the parts, releasing the handle 9, the toolbox assembly is pulled back to its initial position by the rebound force of the first spring 5, thus avoiding interference with the aircraft assembly process.

[0023] Example 2

[0024] like Figure 1-3As shown, the present invention proposes an aircraft assembly jig tooling with a rotating structure. Compared with Embodiment 1, this embodiment also includes a loading tray 10. A rotating rod 15 is fixedly connected to the bottom of the loading tray 10. A foot-kick resistance component is provided on the periphery of the bottom end of the rotating rod 15, and the foot-kick resistance component is used to limit and fix the rotation of the rotating rod 15.

[0025] In this embodiment: a circular through hole is provided in the middle of the assembly table 1, and the rotating rod 15 passes through the circular through hole; multiple levers 11 are fixedly connected to the outer arc surface of the loading tray 10; the foot-kick resistance assembly includes a resistance box 16 fixed on the ground, and the rotating rod 15 is rotatably inserted into the inside of the resistance box 16. An arc-shaped resistance plate 19 is slidably connected inside the resistance box 16. A second spring 20 is fixedly connected between one side of the arc-shaped resistance plate 19 and the inner wall of the resistance box 16. Two connecting rods 17 are fixedly connected to the other side of the arc-shaped resistance plate 19. The ends of the two connecting rods 17 away from the arc-shaped resistance plate 19 move through the outer wall of the resistance box 16 and are jointly fixedly connected to a kick plate 18.

[0026] Working principle: When one side of the aircraft is assembled and the position needs to be adjusted to assemble the other side, kicking the kick plate 18 causes the arc-shaped resistance plate 19 to slide away from the rotating rod 15 under the connection of the connecting rod 17. The arc-shaped resistance plate 19 releases the rotating rod 15, thereby restoring the rotation ability of the loading tray 10. Then, the lever 11 can be used to rotate the loading tray 10 and the aircraft above it to a suitable angle for continued assembly. There is no need to manually adjust the position of the aircraft, making it more convenient to use. After the angle is selected, the kick plate 18 is released. Under the rebound force of the second spring 20, the arc-shaped resistance plate 19 slides and re-locks the bottom periphery of the rotating rod 15. Under the frictional resistance, the rotation of the rotating rod 15 and the loading tray 10 is restricted, thereby ensuring the overall structural stability during the assembly of the aircraft.

[0027] The above specific embodiments are merely several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
