[0031] In this embodiment, if Figure 1 As shown, the arrangement of multiple telescopic frames 20 allows the height of the frame to be flexibly adjusted to accommodate frames of different sizes. The arrangement of two rotating frames 30 allows the side frames to be conveniently docked with the main frame, thereby improving the accuracy and efficiency of welding. The arrangement of multiple sets of fixing components 40 allows the frame to be fixed at multiple points, thereby ensuring the stability and accuracy of the frame during the welding process.

[0032] Further, in some implementations of this embodiment, Figure 1 and Figure 3 As shown, the tooling also includes: two support plates 11, two mounting plates 12, and two first driving members 13. The two support plates 11 are mounted on the base 10; the two mounting plates 12 are mounted on the two support plates 11 one by one, and there are rotating holes on the mounting plates 12, and the rotating frame 30 is rotatably mounted in the rotating holes; the two first driving members 13 are mounted on the base 10 corresponding to the two support plates 11, and are in transmission connection with the rotating frame 30.

[0033] In this embodiment, if Figure 3 As shown, the support plate 11 is a square plate, and the bottom of the support plate 11 is fixed on the base 10, which can be fixed by welding, bolting, etc. The support plate 11 provides a stable installation platform for the mounting plate 12, and the mounting plate 12 is a structural plate with two group supports.

The support rod 24 provides a stable installation platform for the fixed assembly 40. The second driving member 14 can be specifically a telescopic cylinder, which is transmission-connected to the guide post 23. The arrangement realizes the automatic control of the telescopic frame 20, and improves the accuracy and efficiency of the adjustment.

[0036] Further, in some implementations of this embodiment, Figure 1 and Figure 4 As shown, the fixing assembly 40 includes: a base 41, a rotating block 42, a first clamping plate 43, and a second clamping plate 44. The base 41 is mounted on the support rod 24; the rotating block 42 is rotatably arranged on the base 41; the first clamping plate 43 is mounted on the rotating block 42; and the second clamping plate 44 is slidably mounted on the rotating block 42 and slides relative to the first clamping plate 43.

[0037] In this embodiment, if Figure 1 As shown, each set of fixing components 40 includes at least three components, which are spaced apart and distributed on the support rod 24. Figure 4 As shown, the base 41 can be fixed on the upper surface of the support rod 24 by welding or other methods, the rotating block 42 is rotatably mounted on the base 41, the rotating block 42 is clamped on both sides of the base 41, the mounting screw is threadedly connected with the base 41 and the rotating block 42, the screw mounted on the rotating member is rotated to fix the rotating block 42 and the base 41, and the first clamping plate 43 and the second clamping plate 44 can be rotated and adjusted relative to the base 41. The first clamping plate 43 and the second clamping plate 44 are arranged to clamp and fix the frame to ensure stability during the welding process.

[0038] Further, in some implementations of this embodiment, Figure 1 and Figure 4 As shown, the first clamping plate 43 and the second clamping plate 44 form a clamping portion, and the clamping portion has a receiving space. The frame is arranged in the receiving space. The first clamping plate 43 and the second clamping plate 44 respectively abut against the side wall of the frame to fix the positional relationship between the frame and the telescopic frame 20.

[0039] In this embodiment, if Figure 1 As shown, the clamping part is mounted on the rotating block 42, and the rotating block 42 rotates relative to the support rod 24, so that the clamping part has the function of adjusting the pitch angle, so that the frame can be easily passed through the multiple groups of fixing components 40, and the frame is fixed by the abutment of the first clamping plate 43 and the second clamping plate 44. This fixing method is simple and effective, and the adjustable angle and the height adjustment of the telescopic rod can ensure the connection accuracy and stability of the frame during the welding process.

[0040] Further, in some implementations of this embodiment, Figure 1 and Figure 4 As shown, the fixing assembly 40 further includes: a plurality of guide blocks 45, a plurality of guide posts 23, and a plurality of springs 48. The plurality of guide blocks 45 are mounted on the second clamping plate 44, a plurality of guide slots 46 are provided on the first clamping plate 43, and the plurality of guide blocks 45 are slidably mounted in the plurality of guide slots 46 in a one-to-one correspondence; the plurality of guide posts 23 are mounted in the plurality of guide slots 46 in a one-to-one correspondence; and the plurality of springs 48 are covered in a one-to-one correspondence on the plurality of guide posts 23 and abut against the inner wall of the guide slot 46.

[0041] In this embodiment, if Figure 4 As shown, by installing springs 48 between the first clamping plate 43 and the second clamping plate 44, when the frame is not installed, multiple springs 48 pull the first clamping plate 43 and the second clamping plate 44 closer to each other. When the frame is installed, the springs 48 exert a force on the second clamping plate 44 toward the first clamping plate 43. After the frame is removed, the second clamping plate 44 can automatically reset when subjected to external force. The arrangement of the guide block 45 and the guide column 23 allows the second clamping plate 44 to slide and adjust on the first clamping plate 43 while maintaining a stable guiding effect, thereby improving the reliability and stability of the fixation.

[0042] Further, in some implementations of this embodiment, Figure 1 and Figure 3 and Figure 5 As shown, the tooling also includes: a plurality of clamping plates 31. The plurality of clamping plates 31 are mounted on the rotating frame 30, and the side frame and the plurality of clamping plates 31 abut against each other to fix the relative position between the side frame and the rotating frame 30.

[0043] In this embodiment, if Figure 3As shown, the clamping plate 31 is divided into multiple layers. The clamping plate 31 allows the side frame to be easily installed on the rotating frame 30 and fixed by abutting against the clamping plate 31. Figure 5 As shown, this fixing method is simple and quick. By clamping the side frame, the rotating frame 30 is rotated in the direction where the multiple telescopic frames 20 are located, so as to quickly install the side frame on both sides of the frame to be welded, thereby improving the convenience and installation efficiency of the side frame during the welding process.

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model.
