This device can accurately and efficiently mark the holes in the curved shell in advance, and can mark the inside and outside of the curved shell.

[0042] See also Figure 1-3 Specifically describing this embodiment, the opening and marking device for the curved shell of the underwater unmanned vehicle is used for marking on the curved shell 100 between the two T-beams 200 of the underwater unmanned vehicle, and includes a frame plate 1, a center axis 2, a gauge plate 3 and a marking needle 4. The two ends of the frame plate 1 are detachably connected to the two T-beams 200 respectively, the center axis 2 is connected to the frame plate 1, one end of the gauge plate 3 is rotatably set on the center axis 2, and the other end is provided with a needle hole, and the marking needle 4 is inserted into the needle hole.

[0043] The opening marking device for the curved shell of the underwater unmanned vehicle can accurately and efficiently mark the through holes in the curved shell 100 in advance, and can mark the inside and outside of the curved shell 100.

[0044] When marking the interior of the curved shell 100, first support the two ends of the frame 1 on the two T-beams 200, so that the lower plane of the frame 1 is aligned with the upper plane of the upper beam 201 of the T-beam 200. This allows the center axis 2 of the through hole 300 to be opened to be perpendicular to the upper beam 201 of the T-beam 200. Then move the frame so that the center axis 2 is located at the center of the through hole 300 to be opened. Then, connect the two ends of the frame 1 to the two T-beams 200, so that the center axis 2 is located at the center of the through hole 300 to be opened. The gauge plate 3 is rotated and set on the center axis 2. Pass the marking needle 4 through the needle hole of the gauge plate 3, and the marking needle 4 can move around the center axis 2 to mark a standard circle inside the curved shell 100. In this embodiment, the center of the through hole 300 to be opened is located in the middle of the two T-beams 200.

[0045] When marking the exterior of the curved shell 100, a hole with a smaller diameter is opened at the approximate location of the through hole 300 to be opened, which can accommodate the central axis 2. The central axis 2 is passed through this hole. The two ends of the frame plate 1 still need to be supported on the two T-beams 200, so that the lower plane of the frame plate 1 is aligned with the upper plane of the upper beam 201 of the T-beam 200. The frame beams are then moved so that the central axis 2 is located at the center of the through hole 300 to be opened. The two ends of the frame plate 1 are then connected to the two T-beams 200. At this time, the gauge plate 3 is located on the outside of the curved shell 100. The marking needle 4 is passed through the needle hole of the gauge plate 3. The marking needle 4 can move around the central axis 2 and mark a standard circle on the exterior of the curved shell 100.

This facilitates finding the center of the through hole 300 to be opened, thereby facilitating movement of the frame 1 to the correct position. In this embodiment, the frame 1 is provided with two scales, which are arranged opposite each other. The zero ends of both scales are located at the central axis 2, with the tail end of one scale located at one end of the frame 1 and the tail end of the other scale located at the other end of the frame 1.

The gauge plate 3 is provided with a second through hole and an abutment surface. The central axis 2 is passed through the second through hole. The limit nut 6 is threadedly engaged with the central axis 2. The two surfaces of the gauge plate 3 can respectively abut the abutment surface and the limit nut 6, allowing the gauge plate 3 to rotate about the central axis 2. The abutment surface and the limit nut 6 can limit the axial movement of the gauge plate 3 along the central axis 2, so that the gauge plate 3 can only rotate about the central axis 2.

[0050] Optionally, the opening and marking device of the curved shell of the underwater unmanned vehicle further includes a locking nut 7, which is threadedly connected to the central shaft 2 and abuts against the limit nut 6. The locking nut 7 can be further tightened.
