[0038] like Figure 1 , Figure 2 , Figure 5 As shown, this embodiment of the utility model provides a welding positioning device for a grid plate, including a first pressure plate 1 and a second pressure plate 2 arranged opposite to each other, with a plurality of positioning rods 3 between them. The first pressure plate 1 has two oppositely arranged first positioning blocks 11 on the side facing the second pressure plate 2, each first positioning block 11 having a first positioning groove 111, the axes of the two first positioning grooves 111 coinciding. A second positioning block 12 is arranged between the two first positioning blocks 11, the second positioning block 12 having a second positioning groove 121. The second pressure plate 2 has two oppositely arranged third positioning blocks 21 on the side facing the first pressure plate 1, each third positioning block 21 having a third positioning groove 211, the axes of the two third positioning grooves 211 coinciding. A fourth positioning block 22 is arranged between the two third positioning blocks 21, the fourth positioning block 22 having a fourth positioning groove 221. The first positioning groove 111 and the third positioning groove 211 are respectively provided to clamp the two sides of the first grid plate, and the second positioning groove 121 and the fourth positioning groove 221 are respectively provided to clamp the two sides of the other grid plate.

[0039] like Figure 9 , Figure 10As shown, in use, the welding positioning device for the grid plate provided in this embodiment of the present invention involves inserting the first grid plate 4 entirely into the two first positioning slots 111 of the first pressure plate 1, using the two first positioning slots 111 to position the first grid plate 4 perpendicular to the plate surface. Then, the second grid plate 5 is inserted into the second positioning slot 121 and aligns with the first grid plate 4 to form a T-shaped structure. If a cross-shaped structure is required, there are two methods: the first method is to place a third grid plate opposite the second grid plate 5 and position it using the corresponding second positioning slot 121, then align the third grid plate with the first grid plate 4 to form a cross-shaped structure; the second method is to provide a slot on the first grid plate 4, with the second grid plate 5 passing through the slot and its two ends inserted into the two second positioning slots 121 respectively, forming a cross-shaped structure. This embodiment uses the second method. Then, place the second pressure plate 2 at the end of the T-shaped or cross-shaped structure away from the first pressure plate 1, and insert the end of the first grid plate 4 away from the first pressure plate 1 into the two third positioning grooves 211 of the second pressure plate 2. The ends of the second grid plate 5 and / or the third grid plate away from the first pressure plate 1 are inserted into the corresponding fourth positioning grooves 221. Finally, the first pressure plate 1 and the second pressure plate 2 are fixedly connected by positioning rods 3. At this point, the first pressure plate 1 and the second pressure plate 2 have positioned the position and angle of each grid plate, and then the joints between the grid plates are welded. The first positioning groove 111, the second positioning groove 121, the third positioning groove 211, and the fourth positioning groove 221 all have a certain length, which can effectively resist shrinkage deformation, protect the flatness of the plate surface, prevent deformation and displacement between grid plates, improve the accuracy after welding, and solve problems such as welding deformation, weld offset, and incomplete fusion of thin grid plates.

[0040] In this embodiment, the first positioning groove 111 and the second positioning groove 121 are perpendicular to each other, and the third positioning groove 211 and the fourth positioning groove 221 are perpendicular to each other, to form a grid structure of T-shaped or cross-shaped nodes. In other embodiments, the first positioning groove 111 and the second positioning groove 121 are not perpendicular to each other, and the third positioning groove 211 and the fourth positioning groove 221 are not perpendicular to each other, to form a grid structure of X-shaped nodes.

[0041] In one embodiment of the present invention, the first positioning groove 111 is correspondingly provided with the third positioning groove 211, so that the two first positioning grooves 111 and the two third positioning grooves 211 are located on the same plane; the second positioning groove 121 located on the same side or both sides of the first grid plate 4 is correspondingly provided with the fourth positioning groove 221, so that they are located in the same plane.

[0042] During the welding process of two grid plates, welding stress deformation will occur. To solve this problem, such as... Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 As shown, in a preferred embodiment of this utility model, the first pressure plate 1 is provided with a first sliding groove 13 corresponding to the second positioning block 12. The second positioning block 12 is slidably disposed in the first sliding groove 13 and fixed in position by a first adjusting bolt 14. The second pressure plate 2 is provided with a second sliding groove 23 corresponding to the fourth positioning block 22. The fourth positioning block 22 is slidably disposed in the second sliding groove 23 and fixed in position by a second adjusting bolt 24. Specifically, the ends of the first adjusting bolt 14 and the second adjusting bolt 24 are provided with adjusting nuts for positioning the second positioning block 12 and the fourth positioning block 22. In this embodiment, according to the estimated welding deformation, the positions of the second positioning block 12 and the fourth positioning block 22 can be adjusted by moving them to pre-deform the second grid plate 5 and / or the third grid plate in the opposite direction to offset the welding stress deformation, so that the product meets the verticality requirements after welding.

[0043] like Figure 3 , Figure 4 , Figure 6 , Figure 7 As shown, in a preferred embodiment of this utility model, both the first slide groove 13 and the second slide groove 23 are arc-shaped. The center of the arc corresponding to the first slide groove 13 is located at the intersection of the axes of the first positioning groove 111 and the second positioning groove 121, and the center of the arc corresponding to the second slide groove 23 is located at the intersection of the axes of the third positioning groove 211 and the fourth positioning groove 221. Further, the second positioning block 12 includes a first body 122 and a first sliding portion 123 connected to the first body 122. The second positioning groove 121 is disposed on the first body 122, and the first sliding portion 123 is slidably disposed within the first slide groove 13. The fourth positioning block 22 includes a second body 222 and a second sliding portion 223 connected to the second body 222. The fourth positioning groove 221 is disposed on the second body 222, and the second sliding portion 223 is slidably disposed within the second slide groove 23. Preferably, the cross-section of the first sliding part 123 corresponds to the cross-section of the first sliding groove 13 to prevent the second positioning block 12 from rotating, and the cross-section of the second sliding part 223 corresponds to the cross-section of the second sliding groove 23 to prevent the fourth positioning block 22 from rotating.

[0044] In other embodiments of this utility model, the first slide groove 13 is straight and perpendicular to the second positioning groove 121, and the second slide groove 23 is straight and perpendicular to the fourth positioning groove 221. At this time, the second positioning block 12 and the fourth positioning block 22 can rotate to a certain extent to adapt to the pre-reverse deformation of the grid plate. After adjusting the angle, the position and angle of the grid plate are fixed by the corresponding first adjusting bolt 14 and second adjusting bolt 24.

[0045] The positioning rod 3 can be directly positioned between the first pressure plate 1 and the second pressure plate 2, or, for ease of assembly and space saving, such as... Figure 1 As shown, in one embodiment of this utility model, the positioning rod 3 is disposed between the corresponding first positioning block 11 and the third positioning block 21. The first positioning block 11 and the third positioning block 21 can be easily machined with corresponding holes to fix the positioning rod 3. Specifically, as shown... Figure 8 As shown, the positioning rod 3 includes a large-diameter section 31 and a small-diameter section 32 connected to each other. The diameter of the large-diameter section 31 is larger than the diameter of the small-diameter section 32. The large-diameter section 31 is fixedly installed in the blind hole 112 of the first positioning block 11 (it can be connected by interference fit or thread). The small-diameter section 32 has external threads and passes through the corresponding through holes 212 of the third positioning block 21 and the second pressure plate 2. The end of the small-diameter section 32 passes through the second pressure plate 2 and is located outside the second pressure plate 2 and is provided with a fixing nut 33. Since the diameter of the large-diameter section 31 is larger than the diameter of the through hole 212 on the third positioning block 21, a limiting platform 34 is formed between the small-diameter section 32 and the large-diameter section 31. The limiting platform 34 supports and limits the third positioning block 21. The distance between the limiting platform 34 and the bottom of the first positioning groove 111 is set according to the width of the grid plate.

[0046] like Figures 1-7 As shown, in one embodiment of this utility model, the first pressure plate 1 and the second pressure plate 2 are circular, and the circumferential end faces of the first pressure plate 1 and the second pressure plate 2 are provided with corresponding positioning planes 6. The positioning planes 6 are used for leveling with a dial indicator when the welding positioning device of the grid plate is mounted on the positioner. Preferably, the positioning planes 6 are located at the midpoint between the first positioning groove 111 and the second positioning groove 121, and at the midpoint between the third positioning groove 211 and the fourth positioning groove 221.

[0047] like Figure 1 , Figure 2 , Figure 5 As shown, in one embodiment of this utility model, the first positioning block 11 and the third positioning block 21 are triangular in shape, with their width gradually increasing from the inside to the outside. This facilitates the installation of the positioning rod 3 while providing good anti-deformation capability, and also provides operating space during welding. Alternatively, the second positioning block 12 and the fourth positioning block 22 can also be triangular in shape, with their width gradually increasing from the inside to the outside, providing operating space during welding while also providing good anti-deformation capability.

[0048] like Figure 1 , Figure 2 , Figure 5 As shown, in one embodiment of this utility model, the first pressure plate 1 and the second pressure plate 2 are provided with a clearance hole in the middle to avoid the process boss structure of the grid plate.

[0049] like Figure 11 As shown, this utility model also provides a welding system for a grid plate, including a positioner 7, a welding device 8, and a welding positioning device for the aforementioned grid plate. The first pressure plate 1 or the second pressure plate 2 is fixedly mounted on the chuck 71 of the positioner 7, and then welding is performed by the welding device 8, such as electron beam, laser, or plasma welding equipment. The positioner 7 can achieve welding at different rotation and tilt angles, as well as high-energy symmetrical welding. By controlling the rotation of the positioner 7, multi-pass welding can be achieved with a single clamping, thereby greatly improving production efficiency. Simultaneously, it ensures perfect fusion at the overlapping positions of grid products, satisfying product dimensions, flatness, position, and perpendicularity requirements while also ensuring product strength.

[0050] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
