By using the clamping assembly, the third hydraulic cylinder 212 is activated to push the wedge block 213. Under the action of the sliding column 209 and the spring 211, it can adapt to materials of different sizes and shapes. The stabilizing assembly includes a second motor 301 fixedly connected to the extension plate 3. A bidirectional thread is fixedly connected to the output end of the second motor 301. The rod 302 has two ends threaded with adjusting plates 304. The top of the welding table 1 has a groove 303. A limiting plate 305 is fixedly connected to the adjusting plate 304. A fourth hydraulic cylinder 306 is fixedly connected to the top of the limiting plate 305. A pressure plate 307 is fixedly connected to the output end of the fourth hydraulic cylinder 306. A fixing plate 308 is provided on the top of the welding table 1. The fixing plate 308 and the movable adjusting plate 304 can place materials of different sizes for welding. The materials to be welded are fixed by the limiting plate 305 and the pressure plate 307. A support leg 4 is fixedly connected to the bottom of the welding table 1. The support leg 4 has four sets and is evenly distributed. An installation platform 501 is fixedly connected to one side of the welding table 1.

[0027] In a preferred embodiment, the sliding plate 202 is slidably connected to the groove 203, the mounting bracket 2 is L-shaped, the rotating bracket 207 is T-shaped, the wedge block 213 is attached to the top of the sliding column 209, the clamping plate 210 slides within the rotating bracket 207, the bottom support plate 208 is trapezoidal, one end of the spring 211 is fixedly connected to the clamping plate 210, and the other end of the spring 211 is fixedly connected to the rotating bracket 207. The sliding column 209 is located above the clamping plate 210, the clamping plate 210 is located above the bottom support plate 208, the adjusting plate 304 is slidably connected to the groove 303, the pressure plate 307 is parallel to the adjusting plate 304, the fixing plate 308 is located between the two sets of adjusting plates 304, and the top of the fixing plate 308 is horizontal to the top of the adjusting plate 304.

[0028] In operation, the mounting frame 2 is positioned on the side where the materials to be welded are placed, with the two sets of materials being welded joined at the middle. When welding is required, the position of the materials is detected by the visual inspection device 502. First, the second hydraulic cylinder 204 is activated to push the rotating frame 207 upward until the bottom support plate 208 is horizontal with the materials. The middle of the bottom support plate 208 is located at the joint of the two sets of materials, and there is a stop block on the back of the materials to limit their movement.

Then, the second hydraulic cylinder 204 is activated to push the rotating frame 207 to continue to rise, so that the rotating frame... The bottom of 207 is higher than the top of the limiting plate 305, which can avoid motion interference when the material is long or wide. Then, the motor 206 is started to drive the rotating frame 207 to rotate. After rotating 90 degrees, the motor 301 is started to drive the bidirectional threaded rod 302 to rotate, so that the two sets of adjusting plates 304 slide towards the middle in the groove 303 at the same time. At this time, the two sides of the material need to be above the adjusting plate 304 and in the middle of the two sets of pressure plates 307. Then, the second hydraulic cylinder 204 is started to drive the rotating frame 207 to descend until the material is placed on the fixed plate 308 and the adjusting plate 304. Finally, the motor 301 is started again to drive the two sets of adjusting plates 304 to move towards the middle until the limiting plate 305 is in contact with the two sides of the material. Then, the fourth hydraulic cylinder 306 is started to drive the pressure plate 307 to descend and press the material to make welding work possible. When unloading, simply lift the two sets of pressure plates 307 and move the two sets of adjusting plates 304 to the sides to remove the material.
