The grid arch is used to bear the weight of the rock and soil above the tunnel and unload it on the tunnel foundation through the tunnel wall. The grid arch is welded by four main bars and multiple butterfly bars to form a grid-like truss structure. This structure is widely used due to its high strength and good stability. Among them, the butterfly bars in the grid play the role of connecting the four main bars, which plays an important role in ensuring the integrity and structural stability of the grid.

The tooling body 1 is the basic supporting structure of the entire device, and includes a first support frame 11, a second support frame 12 and a workpiece mounting frame 13. The workpiece mounting frame 13 is installed between the first support frame 11 and the second support frame 12 to ensure the stability and load-bearing capacity of the workpiece mounting frame 13.

[0036] like Figure 1 As shown, in this embodiment, the workpiece mounting frame 13 is further divided into a mounting frame 131 and a plurality of connecting beams 132. The mounting frame 131 is a part directly connected to the rotating assembly 3, and its structural design can withstand the rotation force and smoothly transmit it to the connecting beams 132. The connecting beams 132 are located inside the mounting frame 131, and both ends of the connecting beams 132 are connected to the mounting frame 131, and the clamping assembly 2 is installed on the connecting beams 132.

[0037] Among them, Figure 2 As shown, the connecting crossbeam 132 includes a support plate 132b and a movable plate 132a. The support plates 132b are located at both ends of the movable plate 132a, and one side of the support plates 132b is fixedly connected to the mounting frame 131, and the movable plate 132a is slidably connected between the two support plates 132b, and the support plates 132b provide a stable supporting force for the movable plate 132a, and the movable plate 132a can adjust its position within a certain range, thereby adjusting the position of the grid arch frame and improving the welding quality.

[0038] like Figure 2 As shown, strip holes 132c are provided at both ends of the movable plate 132a and on the supporting plate 132b, and fixing members 132d, such as bolts and nuts, are passed through the strip holes 132c. By tightening the fixing members 132d, the movable plate 132a and the supporting plate 132b can be relatively fixed, thereby ensuring the overall stability of the connecting beam 132 during the welding process.

[0039] like Figure 1-2 As shown, there are multiple groups of clamping assemblies 2, wherein the number of clamping assemblies 2 corresponds to the number of connecting beams 132, and its main function is to firmly clamp the grid arch workpiece to be welded to meet the needs of clamping multiple main bars and butterfly bars at the same time.

[0040] Specifically, the clamping assembly 2 includes a first clamping member 21 and a second clamping member 22. Two groups of the first clamping members 21 are provided, which are respectively located on both sides of the grid arch frame to stably clamp the main ribs. The second clamping member 22 is located in the middle of the two groups of the first clamping members 21 to clamp the butterfly ribs in the grid arch frame.

When the rotating driving member 31 is started, its output shaft drives the driving gear 311 to rotate, and then drives the driven gear 322 and the first rotating shaft 321 to rotate, and finally realizes the smooth rotation of the workpiece mounting frame 13, ensuring the stable progress of the welding operation. The workpiece mounting frame 13 can be rotated at any angle by the driving of the rotating assembly 3, making the welding operation more flexible and convenient. The staff can adjust the rotation angle of the workpiece mounting frame 13 according to actual needs to achieve the best welding position, thereby improving the welding quality and efficiency.

[0044] like Figure 4 As shown, a welding part 4 is also provided on one side of the tooling body 1, and the welding part 4 is equipped with advanced welding equipment, such as a welding gun, a welding power source, etc. After the workpiece is firmly clamped by the clamping assembly 2 and adjusted to a suitable position by the rotating assembly 3, the welding part 4 can perform precise welding operations on the grid arch frame to improve welding efficiency.

[0045] Working principle: First, the operator places the grid arch workpiece to be welded, including the main ribs and butterfly ribs, on the workpiece mounting frame 13. Adjust the position of the movable plate 132a on the connecting beam 132 so that the contact points of the main ribs and the butterfly ribs are accurately aligned. Subsequently, adjust the clamping assembly 2 to ensure that the main ribs and the butterfly ribs are firmly clamped in the set position. Next, start the rotating assembly 3 and adjust the rotation angle of the workpiece mounting frame 13 according to the welding requirements. When the workpiece mounting frame 13 is rotated to a suitable position, the welding part 4 starts working to weld the various connection points of the grid arch.
