Similarly, on both sides of the second main board 120, a water inlet 121 and a water outlet 122 of the water flow channel are provided. The water flows into the water flow channel from the water inlet 121 , and then flows out from the water outlet 112 to take away heat from the first main board 110 and the second main board 120 for cooling.

When welding smaller thin-plate workpieces, adjust the angle of the angle scale 130 according to the required welding angle, so that the angle between the first main board 110 and the second main board 120 is equal to the required angle between two thin-plate workpieces. Then, the first main board 110 and the second main board 120 are relatively fixed by tightening the fastening knob 132 to ensure that the angle between them remains unchanged.

The first main board 110 and the second main board 120 are used as the bottom plates for welding, so that the first main board 110 and the second main board 120 form an inverted "V" shape, and two pieces of waiting plates are respectively placed above the first main board 110 and the second main board 120. For the thin plate workpiece to be welded, the first sub-plate 140 and the second sub-plate 150 are respectively placed on top of the two thin plates to be welded. Wherein, the structure of the first sub-board 140 and the second sub-board 150 is the same as that of the first main board 110 and the second main board 120 , and a water flow channel is also arranged inside, and a water inlet 111 and a water outlet 112 are respectively arranged at both ends. The first sub-board 140 is placed on the top of the first main board 110, so that the first main board 110 and the first sub-board 140 clamp a thin plate workpiece to be welded; the second sub-board 150 is placed on the top of the second main board 120, Make the second main board 120 and the second sub-board 150 sandwich another thin plate workpiece to be welded.

Similarly, the connecting hose 113 is used to communicate the water passages of the second main board 120 and the second sub-board 150 . As a kind of preference, the water inlet 111 and the water outlet 112 on each main board and sub-board are equipped with a quick connector female end with an external thread, and a quick connector male end is installed at both ends of the connecting hose 113, Thus, quick installation or removal of the connecting hose 113 is realized.

In another embodiment, when welding larger thin-plate workpieces, since the transverse lengths of the first main board 110 and the second main board 120 are not enough to support the thin-plate workpieces, it is necessary to place the first main board 110 and the second main board 120 horizontally The length is extended. As shown in FIG. 3 , three extension boards 170 are sequentially connected to the right side of the first main board 110 . A water flow channel is also arranged inside the extension board 170 , and a water inlet 111 and a water outlet 112 are also arranged on both sides of the extension board 170 .

When placing the first sub-plate 140, it is inevitable that the first sub-plate 140 will drive the workpiece to shake slightly, thereby changing the position of the workpiece. Therefore, it is necessary to constantly adjust the position of the workpiece to make it in a more accurate position Position of welding. Therefore, a double-rocker mechanism is used to limit the movement track of the first sub-plate 140, so that when it is placed on the first main board 110, at the position about to be in contact with the workpiece, the movement path of the first sub-plate 140 follows the first main board 110. The direction of the line, so that the first sub-plate 140 will only clamp the workpiece without shaking it, so that the workpiece is always in an accurate position, avoiding re-adjustment of the workpiece position, and improving efficiency and welding quality.

The double rocker mechanism includes a connecting rod 181 , a frame 182 , a first rocker 183 and a second rocker 184 .
