DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer toFigures 1-5 , the present utility model provides a technical solution: a device for assembling and positioning composite plates of an aircraft overhead bin, including a base 1, a workbench 2, positioning clamps 3, a first pin 4 and a second pin 5. Positioning frames 6 are fixedly connected to the top ends of the workbench 2. Multiple gripping grooves 7 are provided on the positioning frames 6. First connection grooves 8 are provided on the positioning frames 6. First connection blocks 9 are fixedly connected to the positioning frames 6. Second connection grooves 10 are provided on the positioning clamps 3. Second connection blocks 11 are fixedly connected to the positioning clamps 3. A pressing screw 12 is threadedly connected to the top end of the side positioning clamp 3. A first stop block 13 is provided at the position corresponding to the pressing screw 12 on the side positioning clamp 3. Multiple second stop blocks 14 are fixedly connected to the side positioning frame 6.

[0019] On one side of the bottom end of the base 1, symmetrically arranged universal casters 15 are provided. On the other side of the bottom end of the base 1, symmetrically arranged directional casters 16 are provided. The universal casters 15 and the directional casters 16 facilitate the movement of the entire base 1. Symmetrically arranged multiple support square steels 17 are fixedly connected to the top end of the base 1. The top ends of the support square steels 17 are fixedly connected to the bottom end of the workbench 2. The support square steels 17 facilitate providing stable support for the workbench 2. A storage box 18 is fixedly connected to the top end of the base 1. The storage box 18 facilitates the storage and access of various tools during the assembly of the overhead bin plates. The second connection block 11 is located inside the first connection groove 8.
