Description

Technical Field

[0001] The utility model relates to the technical field of aviation equipment, and in particular to an eVTOL aircraft wing assembly tool. Background Art

[0002] The wings of the eVTOL aircraft are composed of a skeleton and skin made of composite materials. The skeleton is composed of span-wise beams and helical ribs. When assembling, the skeleton is first connected together by fasteners, and then connected to the skin. The skin of the eVTOL aircraft wing is thin and cannot be installed with countersunk fasteners. Generally, structural adhesive is used to glue the wing skin and wing skeleton together. The bonding requires pressurization of the bonding surface to ensure the thickness and bonding quality of the adhesive layer. When assembling the eVTOL wing, it is necessary to use assembly tooling to complete the positioning of parts, the connection of beams and ribs, and the connection of skin and skeleton, to ensure the shape accuracy of the skin and the connection accuracy of the skeleton, and to meet the assembly accuracy requirements of the aircraft. However, some existing aircraft wing assembly devices are vertical structures, such as the Chinese invention patent "Aircraft Wing Assembly Device and Assembly Method" with application number 202210695677.6, which is suitable for wing structures installed with fasteners. For wing structures where the wing skeleton and wing skin need to be glued, the structural adhesive is easy to lose, resulting in bonding defects. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means for realizing the utility model, creative features, objectives and effects easy to understand, the utility model is further explained below in conjunction with specific diagrams. In the description of the utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, an integral connection or a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be internal communication between two components.

[0022] Example

[0023] like Figure 1 and Figure 2 As shown, when the wing skin is glued, in order to improve the quality of the glue and prevent the structural glue from flowing away due to gravity, the assembly tool 1 needs to place the eVTOL aircraft wing 2 horizontally. Since the eVTOL aircraft wing 2 is large in size, when assembling the wing frame, it is very inconvenient for the operator to punch holes in the middle of the wing frame and install fasteners when it is placed horizontally. The workers need to bend over, which is harmful to the health of the operators. Therefore, the wing frame needs to be fixed vertically to complete the positioning and assembly of the frame.

[0024] In view of the above requirements, the assembly tool 1 includes a support frame 11 and a tool body 12. There are two support frames 11. The tool body 12 is installed between the two support frames 11 through a limiting structure. By adjusting the relationship between the support frame 11 and the tool body 12, the assembly tool 1 can be kept in a vertical state when assembling the wing frame, and can be kept in a horizontal state when assembling the wing skin.

[0025] like Figure 3 As shown, the tool body 12 includes a frame 121, and a long card assembly 122 and a short card assembly 123 fixed on the frame 121. The tool body 12 provides overall support, and the frame 121 is formed by welding and shaping standard steel profiles; the limiting structure includes a sleeve 111, an axis 1211 and a pin hole 1212, and the axis 1211 is installed at both ends of the frame 121. The axis 1211 is a circular axis, which is used in conjunction with the sleeve 111 on the support frame 11 to enable the tool body 12 to rotate around the axis 1211; the pin hole 1212 is opened at both ends of the support frame 11 and the frame 121, wherein two pin holes 1212 are provided at both ends of the frame 121, respectively located on both sides of the sleeve 111, and two groups of pin holes 1212 are provided on the support frame 11, and the two groups of pin holes 1212 are distributed in a cross, and the position between each group of pin holes 1212 corresponds to the position of the pin holes 1212 at the end of the frame 121, and the pin 112 is detachably installed inside.

[0026] When the tooling body 12 is horizontal or vertical, the tooling body 12 is fixed in the required state by the pin 112 on the support frame 11 and the pin hole 1212. The multiple long card assembly 122 and short card assembly 123 on the tooling body 12 are consistent with the rib position of the wing frame 21 to maintain the accuracy of the wing shape after assembly.

[0027] like Figure 4 As shown, the support frame 11 is provided with a sleeve 111 and a pin 112. The pin 112 is a separate structure. By cooperating with the pin hole 1212 on the support frame 11, the sleeve 111 cooperates with the shaft 1211 to ensure that the shaft 1211 can rotate effectively. When the tool body 12 is placed horizontally, the pin 112 is inserted into the horizontal hole of the support frame 11, and then penetrates into the pin hole 1212 on the frame 121, so that the fixation is completed. When the tool body 12 is placed vertically, the pin 112 is inserted into the vertical hole of the support frame 11, and penetrates into the pin hole 1212 on the frame 121, so that the fixation of the tool body 12 is completed. The head of the pin 112 is a conical structure, which is convenient for insertion into the hole.

[0028] like Figure 5 As shown, the long card assembly 122 includes a long card body 1221 and a beam positioning block 1222. The long card body 1221 is processed according to the theoretical shape, and clamps the wing skin as a whole along the wing chord direction, exerting pressure on the structural adhesive to ensure the quality of the bonding. The beam positioning block 1222 positions the beam to ensure the accuracy of the front and rear beams and meet the force requirements of the beam.

[0029] like Figure 6 As shown, the short card assembly 123 includes a short card body 1231 and a rib positioning block 1232. The short card body 1231 is processed according to the theoretical shape, clamps the wing skin, applies pressure to the structural adhesive, and ensures the quality of the bonding. The rib positioning block 1232 positions the rib to ensure the positioning accuracy of the rib.

[0030] Figure 5 and Figure 6 The middle and long pallet body 1221 and the short pallet body 1231 can be a metal structure or a non-metal structure, and are preferably made of wood substitutes, which are soft and will not damage the wing skin. The beam positioning block 1222 and the rib positioning block 1232 are both detachable structures. When assembling the skeleton, they are installed on the long pallet body 1221 and the short pallet body 1231. When assembling the wing skin, they need to be disassembled, and only the long pallet body 1221 and the short pallet body 1231 are used to press the wing skin.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
