They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0028] Please see the appendix Figure 1 and attached Figure 2 This embodiment relates to an adjustment device for assembling and adjusting the slats and rails of an aircraft wing. During the assembly and adjustment process, the slats and rails are adjusted by an eccentric bushing and connected by bolts.

[0029] The adjustment device includes a main body 100, on which an adjustment groove 110 is provided. The adjustment groove 110 is fitted onto the eccentric bushing. The eccentric bushing is rotated by rotating the main body 100. A boss 111 is provided on the bottom wall of the adjustment groove 110. The boss 111 can be placed in the groove of the bolt head to restrict the rotation of the bolt.

[0030] Specifically, the main body 100 has a cylindrical block structure, with its diameter slightly larger than its height. An adjustment groove 110 is provided on the main body 100. When this adjustment device is in use, the adjustment groove 110 is first fastened onto the eccentric bushing. Rotating the main body 100 causes the adjustment groove 110 to rotate. It should be noted that during the rotation of the main body 100, the boss 111 is not placed in the groove of the bolt head. Therefore, when the eccentric bushing rotates, the bolt remains relatively stationary. After the position of the eccentric bushing is adjusted, the bolt is slightly rotated at a certain angle on the side away from the head so that the boss 111 can be placed in the groove of the bolt head. A certain force can be applied to the bolt head to restrict its rotation. Then, the nut is tightened on the other side of the bolt to lock the entire bolt and prevent it from rotating.

[0031] With this adjustment device, the installation of slat control surfaces on the leading edge of aircraft wings can be completed by one person without the need for both a sleeve tool and a bolt fixing clamp. This reduces the difficulty of coordination for multiple operators, avoids the risk of loosening during the tightening process, and eliminates the risk of damage to assembly personnel and products. It improves convenience and avoids problems of poor coordination and low safety. On the other hand, this adjustment device has a simple and reliable structure, which can improve operating efficiency, installation quality, and economic benefits.

[0032] Optionally, one side of the main body 100 is recessed inward to form an adjustment groove 110, which is clearance-fitted with the eccentric bushing.

[0033] In this embodiment, the adjustment groove 110 and the eccentric bushing are fitted together to ensure that the main body 100 can be easily fitted when the eccentric bushing is installed, thereby improving the operating efficiency.

[0034] Optionally, the cross-sectional shape of the adjusting groove 110 is matched with the shape of the mating part of the eccentric bushing.

[0035] In this embodiment, the mating part of the eccentric bushing has a prism structure, specifically a hexagonal prism. Adaptively, the cross-sectional shape of the adjusting groove 110 is also a hexagonal structure. That is, the adjusting groove 110 is a hexagonal prism groove adapted to the mating structure of the eccentric bushing. Of course, in other embodiments, the cross-sectional shape of the adjusting groove 110 can also be other polygonal structures to adapt to the shape of the mating part of the eccentric bushing.

[0036] Furthermore, the opening of the adjusting groove 110 is transitioned by an arc surface.

[0037] In this embodiment, the edges of the groove opening of the adjustment groove 110 are all connected with arc surfaces, which can ensure that the main body 100 can be fitted with the eccentric bushing more smoothly and without jamming.

[0038] Optionally, the boss 111 and the main body 100 are an integral structure.

[0039] In this embodiment, the boss 111 can be integrally cast or directly milled inside the adjusting groove 110. Of course, in other embodiments, the boss 111 can also be welded or threaded onto the bottom wall of the adjusting groove 110. The specific forming method can be selected according to the difficulty and cost of processing.

[0040] Optionally, the boss 111 has a strip-shaped structure.

[0041] The head of a bolt is usually provided with a slotted groove. To accommodate the slotted groove, the boss 111 is also a slotted strip structure. At the same time, the width of the boss 111 is smaller than that of the slotted groove to ensure a clearance fit between the two.

[0042] Alternatively, the length of the boss 111 matches the length of the groove in the bolt head.

[0043] In this embodiment, the length of the boss 111 is slightly smaller than the length of the groove in the bolt head to avoid the length of the boss 111 being too small compared to the length of the groove in the bolt head. This prevents stress concentration between the boss 111 and the groove when the bolt is tightened on the other side, thus avoiding damage to the bolt during the tightening process and ensuring the stability of the bolt during the assembly process.

[0044] Optionally, a connecting portion 120 is provided on the other side of the main body 100 opposite to the adjustment groove 110. The connecting portion 120 is used to cooperate with a clamping tool to limit the rotation of the main body 100.

[0045] In this embodiment, a connecting part 120 protrudes from the other side of the main body 100. A fixed-force wrench can be used as the clamping tool to ensure stable clamping of the connecting part 120, thereby limiting the rotation of the main body 100.

[0046] Furthermore, the connecting part 120 is a prism-shaped boss.

[0047] In this embodiment, the connecting part 120 is a hexagonal prism-shaped boss that is inserted into the fixed-force wrench, thereby restricting the rotation of the main body 100.

[0048] It should be noted that a series of adjustment devices of different specifications can be adaptively designed according to the specific dimensions and specifications of the eccentric bushing and bolts. In the actual assembly process, the corresponding size adjustment device can be selected as needed, which further improves the versatility of this adjustment device.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
