[0029] The above solution involves setting up a positioning device 7 to position the sheet metal, making it easier for users to weld the sheet metal.
[0030] refer to Figure 3 The adjusting device 9 includes a dual-head motor 901, the output end of which is fixedly connected to a screw 902, and a movable plate 903 is sleeved on the surface of the screw 902.
[0031] The above solution allows for the adjustment of the positioning plate 4 by setting the adjustment device 9, making it convenient for users to weld plates of different sizes.
[0032] refer to Figure 1 and Figure 2 The mounting plate 3 is fixedly connected to the spot welding machine 1 on the side closest to the spot welding machine 1. The top of the mounting plate 3 is fixedly connected to the processing table 2. There are multiple rotating wheels 6, which are evenly distributed at the bottom of the cavity of the receiving groove 5. The bottom of the support plate 8 is fixedly connected to the processing table 2.
[0033] The above solution is adopted: by setting the mounting plate 3, the processing table 2 can be supported, and by setting the rotating wheels 6, the user can easily move the board.
[0034] refer to Figure 2 and Figure 3 A rectangular through hole 10 is provided on the front side of the support plate 8. Sliding columns 11 that cooperate with the moving plate 903 are provided at the top and bottom of the inner cavity of the rectangular through hole 10.

[0037] The above solution is as follows: by setting up a support frame 701, the positioning column 702 can be supported; by setting up a positioning column 702, the plate can be positioned; by setting up a limiting column 703 and a limiting plate 705, the support frame 701 can be moved and the support frame 701 can be limited; by setting up a tension spring 704, the limiting column 703 and the limiting plate 705 can be reset.

[0040] The working principle of this utility model:
[0041] In operation, two plates to be welded are passed between the rotating wheel 6 and the positioning post 702. As the plates enter, they press against the positioning post 702. This pressure pushes the positioning post 702, support frame 701, limit post 703, and limit plate 705 upwards simultaneously, stretching the tension spring 704. The force released by the stretched tension spring 704 pulls the positioning post 702, support frame 701, limit post 703, and limit plate 705 downwards simultaneously, bringing the positioning post 702 into contact with the plates and positioning them. Then, the motor is started, driving the screw 902 to rotate. During rotation, the screw 902 moves the moving plate 903 across the surface of the sliding post 11, which in turn moves the positioning plate 4. When the positioning plate 4 reaches the appropriate position, the two plates align. The motor is then stopped, and the spot welding machine 1 is started. The user then slowly moves the plate 903 forward to weld the plates, completing the work.
[0042] In summary, the positioning device 7 for sheet metal welding processing, through the coordinated use of a processing table 2, mounting plate 3, positioning plate 4, receiving groove 5, rotating wheel 6, positioning device 7, support plate 8, and adjustment device 9, solves the problem that most existing spot welding machines lack the function of positioning the plates when welding two plates. Usually, the two plates need to be aligned manually before welding, which is inconvenient and may cause displacement of the plates due to improper operation, affecting the welding quality.
