[0049] According to a preferred implementation, this embodiment also provides an automated skin trimming method for a target drone assembly production line, and the method is implemented using the automated skin trimming device for a target drone assembly production line described in any technical solution of this embodiment. Specifically, the method comprises the following steps:

[0050] S1: Target drone assembly. Preferably, the fuselage frame is assembled using a final assembly jig.

[0051] Specifically, the target frame includes a first frame 41, a second frame 42, a third frame 43, a fourth frame 44, a fifth frame 45, a sixth frame 46, a seventh frame 47, an eighth frame 48, and a first upper long girder 411 and a first lower long girder 412 connected between the first frame 41 and the third frame 43, a second upper long girder 451 and a second lower long girder 452 connected between the fifth frame 45 and the seventh frame 47, a positioning locking mechanism 441 located between the fourth frame 44 and the fifth frame 45, and a reinforcing rib 471 located between the seventh frame 47 and the eighth frame 48. Preferably, the various parts of the target frame can be riveted together using the riveting method in the prior art. The schematic diagram of the assembled target frame is shown in FIG. Figure 3 shown.

[0052] S2: Fuselage skin. Preferably, the fuselage skin is an integrated skin. More preferably, the front equipment compartment, fuel tank and rear equipment compartment of the fuselage are an integrated skin, and the fuselage skin is tightened and fitted to the frame through the assembly jig.

[0053] Specifically, the frames of the target drone are positioned by the assembly jig, and then the long stringers and fuselage skins are assembled between the frames, initial holes with a diameter of 2.6 mm are made on the skins and the fuselage, and the skins and the fuselage are fixed with connecting bolts. For example, 3 to 5 positioning holes are made between each frame to lock and position the various components of the fuselage and the skins and the fuselage to form the target drone 4 to be trimmed. The position of the bolt positioning hole 49 is as shown in FIG. Figure 1 shown.

[0054] S3: Install the target drone 4 to be trimmed. Remove the target drone 4 to be trimmed and install it on the automatic skin trimming device.

[0055] Specifically, the target drone 4 to be trimmed is removed, and the first frame 41 and the eighth frame 48 of the fuselage are respectively installed on the first installation frame 112 and the second installation frame 122, and are fastened and fixed by screws.

[0056] S4: trimming the target drone 4. Preferably, the fuselage skin is trimmed using a numerical control program provided by a technician.

[0057] Specifically, the target drone 4 to be trimmed is driven by the rotation of the rotary drive mechanism, and the trimming mechanism slides in the horizontal direction and the connecting arm 32 and / or the mobile mechanical arm 33 rotate to achieve the whole machine skin trimming.

[0058] The trimming method of this embodiment uses CNC equipment for trimming, so it does not use conventional repair schemes for construction. Conventional skin repair schemes are to first make positioning holes and position the skin, then make other holes, remove the skin after marking the lines according to the tooling, and perform manual repair. The trimming method of this embodiment uses CNC processing technology for repair, which is to first assemble the body before trimming, make a positioning hole with a diameter of 2.6mm, fix and lock it, and then fix it on the trimming device to ensure that the skin is fastened to the body structure without deviation, and then perform the skin repair process.

[0059] Preferably, the positioning holes at the junction of the skin and the frame and the skin and the long stringer should not be locked, because CNC trimming will damage the frame and the long stringer, affecting the strength of the aircraft. By retaining a certain margin and not locking it, the skin at this place can be manually trimmed after being removed from the frame. After completing CNC trimming, remove the fuselage, and manually trim the places where the trimming device cannot be repaired, and then inspect and accept them for subsequent work.

[0060] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
