[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0021] See Figures 1 to 3 The arc-shaped baffle welding jig includes a base frame 1, positioning blocks 2, and a fixing fixture 3. Multiple positioning blocks 2 are arranged side by side and spaced apart on the base frame 1. The positioning blocks 2 have arc-shaped upper surfaces for supporting the arc-shaped baffle. The fixing fixture 3 is detachably connected to the positioning blocks 2 to secure the arc-shaped baffle and the positioning blocks 2.

[0022] When welding the arc baffle, the arc baffle is completely fitted to the arc surface and then fixed with the fixing fixture 3 , thereby greatly reducing the welding deformation of the arc baffle and alleviating the workload of subsequent processing.

[0023] In some embodiments, the base frame 1 includes legs 11 and a mounting frame 12. The upper ends of the legs 11 are respectively connected to the mounting frame 12, and the positioning blocks 3 are connected to the mounting frame 12. The legs 11 are used to support the entire upper structure.

[0024] In some embodiments, the chassis 1 further includes at least one slide plate 13. The inner wall of the mounting frame 12 is formed with grooves. The ends of the slide plate 13 are inserted into the guide grooves and can slide along the grooves. The positioning block 2 is detachably connected to the slide plate 13. When welding different curved baffles, the corresponding positioning block 2 is selected and the corresponding positioning block 2 is installed by moving the slide plate 13.

[0025] In some embodiments, the chassis 1 further includes a baffle 14, which is fixedly connected to a side of the mounting frame 12 and extends above the mounting frame 12. The slide 13 is arranged parallel to the baffle 14, and one end of the positioning block 2 abuts against the baffle 14. After the positioning block 2 is mounted on the slide 13, the slide 13 is moved so that the positioning block 2 abuts against the baffle 14, thereby completing the positioning of the positioning block 2.

[0026] In some embodiments, chassis 1 further includes an elastic member connecting slide 13 and mounting frame 12. The elastic force of the elastic member propels slide 13 toward baffle 14. This elastic force pushes positioning block 2 against baffle 14, preventing movement of positioning block 2 during welding. The elastic member can be a spring and is preferably embedded in a groove.

[0027] In some embodiments, a first mounting hole is formed on the slide plate 13 , the positioning block 2 has a second mounting hole corresponding to the first connection hole, and the base frame 1 further includes a connecting member 15 connecting the first mounting hole and the second mounting hole.

[0028] In a preferred embodiment, the first and second mounting holes have identical internal threads, and the connecting member 15 is a bolt having external threads corresponding to the internal threads. The bolt is screwed into the mounting hole to secure the connection. Furthermore, auxiliary components such as washers may be used in the bolt connection.

[0029] In some embodiments, there are at least two sets of fixing clamps 3, which fix the curved baffle and positioning block 2 from different directions. For example, they can be connected and fixed from the horizontal and vertical directions to prevent the curved baffle from sliding. In a preferred embodiment, the fixing clamps 3 are C-shaped clamps.

[0030] Compared with the existing technology, the arc baffle welding jig provided by the utility model uses a positioning block to support the arc baffle, so that the arc baffle is completely fitted into the arc surface, and then uses a fixing clamp to fix the arc baffle, thereby greatly reducing the welding deformation of the arc baffle when welding the arc baffle, and reducing the workload of subsequent processing.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
