It can be supported by a rotary structure, which is a conventional technical means in this field and will not be described in detail here.

[0044] Rotary seat 4 is provided at each of the four corners of the main seat 2, that is, four rotating seats 4 are distributed at equal angular intervals. The rotating seats 4 are rotatably mounted on the main seat 2. The rotating seats 4 are driven to rotate by the second rotating motor 5 mounted on the main seat 2. The structure of the rotating support is a conventional technical means in this field and will not be described in detail here.

[0045] Four rotating seats 4 are distributed at equal angles to ensure the rotational balance of the main seat 2. Multiple rotating seats 4 can be set up to have multiple fixed positions of the skeleton 27, which is beneficial to improving efficiency.

[0048] There are four bottom support components, which are set on the rotating base 4, with two on each side of the placement platform 6. The bottom support components include a bottom support frame 7 set on the rotating base 4. The bottom support frame 7 has two support wheels 8 with an axial angle of 90 degrees on its top. The support wheels 8 can be rotatable rubber wheels. Through the setting of multiple bottom support components, the two support wheels 8 with an axial angle of 90 degrees can support and limit the frame 27 from the bottom.

[0049] The positioning block 9 is positioned on the rear side of the placement platform 6 to position the skeleton 27 from the rear and limit the rear side of the skeleton 27.

When the third positioning cylinder B18 retracts, it drives the third clamping rod 20 to move and clamp the frame 27. The third positioning cylinder C19 cooperates with the third positioning block 17 to clamp the frame 27. By setting the third positioning cylinder A15, the third positioning block 17 can be driven to approach and fit tightly against the frame 27. Under the drive of the third positioning cylinder B18, the third clamping rod 20 can fix the frame 27 on the third positioning block 17. The third positioning cylinder C19 cooperates with the third positioning block 17 to clamp the frame 27, thus realizing the clamping and positioning of the frame 27.

[0055] The fourth positioning component, which has multiple components distributed on the side frame 14, can be adjusted according to actual needs and is used to clamp and fix the frame 27 at different positions.

[0056] The fourth positioning assembly includes a fourth positioning cylinder A21, a fourth positioning seat 22, a fourth positioning block 23, a fourth positioning cylinder B24, and a fourth positioning cylinder C25. The fourth positioning cylinder A21 is mounted on the side frame 14 via the fourth positioning cylinder seat.

The fourth positioning cylinder C25 cooperates with the fourth positioning block 23 to clamp the frame 27. By setting the fourth positioning cylinder A21, the fourth positioning block 23 can be driven to approach and fit tightly against the frame 27. The fourth positioning block 23 has a U-shaped structure design, which can perform initial positioning of the frame 27. Under the drive of the fourth positioning cylinder B24, the fourth clamping rod 26 can press the frame 27 onto the fourth positioning block 23. The fourth positioning cylinder C25 cooperates with the fourth positioning block 23 to clamp the frame 27, thus realizing the clamping and positioning of the frame 27.

[0057] The main seat 2 is rotatably mounted on the base 1. The main seat 2 is equipped with multiple rotating seats 4, each of which is equipped with a positioning mechanism. This enables multiple workstations for fixing the skeleton 27, allowing for multi-position and multi-angle adjustment of the skeleton 27 to be riveted, facilitating subsequent riveting operations. Through the setting of limit blocks and multiple positioning components, the skeleton 27 to be riveted can be stably fixed by the positioning mechanism, realizing the assembly of the skeleton 27, reducing manual labor, ensuring the accuracy of the riveting points, and improving riveting efficiency and output.
