Description

Technical Field

[0001] This utility model relates to the field of aircraft assembly technology, specifically to a precision frame for fuselage frame docking. Background Technology

[0002] In the field of modern aviation manufacturing, the precise docking of fuselage frames is a key step in ensuring the structural integrity and assembly quality of an aircraft.

[0003] The prior art provides a fuselage docking frame tooling (publication number CN213616545U). This utility model includes a base, on which a movable base and a fixed base are provided. The movable base is fitted into a slide rail of the base, and a moving groove is provided between the slide rails. A first hydraulic actuator is provided at one end of the base. An equipment box is provided at the bottom of the movable base. The equipment box is fitted into the moving groove and fixed to the pushing column of the first hydraulic actuator. A carrier plate is provided inside the movable base. The carrier plate is fitted into the slide rails on both sides of the movable base. Fixed plates are provided on the outside of both sides of the movable base. The fixed plates are fixed to both ends of the carrier plate through connecting rods passing through the slide rails.

[0004] The aforementioned fuselage docking frame fixture lacks fuselage adjustment during actual use. Once a misalignment occurs during fuselage docking, it is not easy to adjust the fuselage. It is necessary to first use a third hydraulic pusher in conjunction with a clamping plate to loosen the constraint on the fuselage, and then adjust the position of the fuselage manually or with auxiliary tools. This adjustment method is not only cumbersome and time-consuming, but also results in low correction efficiency and affects assembly efficiency. Therefore, we need to propose a precision fixture for fuselage frame docking. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A precision frame for docking fuselage segments includes a movable plate 4. Multiple sets of support mechanisms for supporting the fuselage are fixedly installed on the top of the movable plate 4. A support plate 16 is provided on the top of the movable plate 4. An arc-shaped guide rail 19 is fixedly connected to the top of the support plate 16. A fixing mechanism for clamping the end of the fuselage is provided on the arc-shaped guide rail 19. An adjustment mechanism for driving the fixing mechanism to rotate and adjust is provided on the side of the support plate 16, which drives the fixing mechanism to adjust the fuselage on the support mechanism.

[0024] In an optional embodiment: the support mechanism includes a second support seat 5, a lifting seat 7, a second support plate 8, a first hydraulic cylinder 9, a push plate 10, and universal balls 11. The second support seat 5 is fixedly connected to the top of the movable plate 4. The lifting seat 7 is fixedly installed on the top of the second support seat 5. The second support plate 8 is fixedly installed on the lifting seat 7. The first hydraulic cylinder 9 is fixedly installed on the side of the second support plate 8. The push plate 10 is fixedly installed on the telescopic end of the first hydraulic cylinder 9. The universal balls 11 are arranged in a rectangular array on the side of the push plate 10.

[0025] It should be noted that when the first hydraulic cylinder 9 is activated, the telescopic end of the first hydraulic cylinder 9 pushes the push plate 10, causing the push plate 10 to move into the clearance groove 12. Then, the universal ball bearing 11 moves out of the second support seat 5 through the through hole 13. When the machine body is placed on the second support plate 8 and needs to be rotated, the universal ball bearing 11 facilitates the movement and adjustment of the machine body.

[0026] In an optional embodiment: the interior of the second support plate 8 is provided with a relief groove 12 for the push plate 10 to avoid, and a first arc-shaped part adapted to the machine body is provided on one side of the second support plate 8. A through hole 13 for the universal ball bearing 11 to avoid is provided on the first arc-shaped part of the second support plate 8, and the through hole 13 is connected to the relief groove 12.

[0027] It should be noted that the first arc-shaped part is designed to facilitate contact with the fuselage and provide support for it.

[0028] In an optional embodiment: the adjustment mechanism includes a drive motor 17, a drive gear 18, an arc-shaped seat 20 and an arc-shaped rack 22. The drive motor 17 is fixedly mounted on the side of the support plate 16, the drive gear 18 is fixedly mounted on the output shaft of the drive motor 17, the arc-shaped seat 20 is slidably mounted on the arc-shaped guide rail 19, and the arc-shaped rack 22 is fixedly connected to the surface of the arc-shaped seat 20. The drive gear 18 meshes with the arc-shaped rack 22.

[0029] It should be noted that when the drive motor 17 is started, the output shaft of the drive motor 17 drives the drive gear 18 to rotate. When the drive gear 18 rotates, it drives the arc rack 22 to move the arc seat 20. When the arc seat 20 moves, it drives the fixing mechanism to move. The movement of the fixing mechanism adjusts the machine body. The drive motor 17 is set as a servo motor with a braking mechanism. When the power is off, the output shaft is quickly locked to ensure that the position of the fixing mechanism is fixed and to prevent the machine body from rotating.

[0030] In an optional embodiment: the fixing mechanism includes a first arc-shaped clamping block 21, a mounting frame 23, a third hydraulic cylinder 24 and a second arc-shaped clamping block 25. The mounting frame 23 is fixedly installed on the side of the arc-shaped seat 20, the first arc-shaped clamping block 21 is fixedly connected to the surface of the arc-shaped seat 20, the third hydraulic cylinder 24 is fixedly installed on the bottom of the mounting frame 23, the second arc-shaped clamping block 25 is fixedly installed on the telescopic end of the third hydraulic cylinder 24, and the second arc-shaped clamping block 25 is slidably installed in the mounting frame 23.

[0031] It should be noted that the first arc-shaped clamping block 21, the mounting bracket 23, the third hydraulic cylinder 24 and the second arc-shaped clamping block 25 cooperate to clamp and fix the machine body. When the adjusting mechanism drives the fixing mechanism to rotate, the fixing mechanism can drive the machine body to rotate.

[0032] In an optional embodiment: a second hydraulic cylinder 14 is fixedly installed on the top of the movable plate 4, and two sets of support rails 15 are symmetrically fixedly installed on the top of the movable plate 4. The support plate 16 is slidably installed on the support rails 15, and the telescopic end of the second hydraulic cylinder 14 is fixedly installed on the side of the support plate 16.

[0033] It should be noted that the second hydraulic cylinder 14 can push the support plate 16, thereby adjusting the position of the support plate 16. When the support plate 16 is adjusted, the support plate 16 drives the fixing mechanism to move closer to the machine body, so that the fixing mechanism can fix the machine body. The support guide rail 15 plays a role in positioning the support plate 16, so that the support plate 16 can move stably.

[0034] In an optional embodiment, it further includes a fixed base 1 and multiple sets of first support bases 2 fixedly installed on the top of the fixed base 1. Each set of first support bases 2 is fixedly installed with a first support plate 3 for supporting the fuselage. A second arc-shaped portion adapted to the fuselage is opened on one side of the first support plate 3.

[0035] It should be noted that the first support base 2 and the first support plate 3 cooperate to support the fuselage, and the second arc-shaped part can easily contact the fuselage to support it.

[0036] The fixed base 1 is fixedly installed on the top of the base plate 6. The mobile device 26 is installed on the base plate 6. The mobile plate 4 is fixedly installed on the mobile device 26. The mobile device 26 can be set as a precision linear guide. The mobile plate 4 is moved by the mobile device 26. Precision linear guides are common knowledge in the field. And this application document is mainly used to protect the structure and shape and their combination. Therefore, this application document will not explain the control method and circuit connection in detail.

[0037] The usage process of this utility model is as follows: First, place the machine body on top of the first support plate 3 and the second support plate 8. Move the moving plate 4 by the moving device 26, thereby moving the machine body on the moving plate 4 closer to the machine body on the top of the fixed base 1. If the end of the machine body on the moving plate 4 is offset, activate the second hydraulic cylinder 14. The telescopic end of the second hydraulic cylinder 14 retracts, causing the support plate 16 to move. This causes the support plate 16 to move the first arc-shaped clamping block 21 and the second arc-shaped clamping block 25 closer to the end of the machine body on the moving plate 4. The first arc-shaped clamping block 21 moves to the bottom of the surface of the machine body, and the second arc-shaped clamping block 25 moves to the inside of the machine body. Activate the third hydraulic cylinder 24. The telescopic end of the third hydraulic cylinder 24 retracts, causing the second arc-shaped clamping block 25 to move. This causes the second arc-shaped clamping block 25 to clamp the inner wall of the machine body and work with the first arc-shaped clamping block 21 to clamp and fix the machine body.

[0038] After the machine body is clamped and fixed, the drive motor 17 is started. The output shaft of the drive motor 17 rotates, driving the drive gear 18 to rotate. When the drive gear 18 rotates, it drives the arc rack 22 to move the arc seat 20 on the arc guide rail 19. This allows the arc seat 20 to make fine adjustments to the machine body during movement, thus completing the calibration of the machine body position.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
