[0042] Working principle: When in use, during welding, the pipe fitting is first clamped and fixed by the clamping and moving module 11, then the rectangular thin plate is placed on the placement plate 1202 and fits against the side wall of the support plate 1201, then the second moving block 602 is driven by the moving module 603 to move in the direction away from the fixed plate 601, and at the same time, the cooling cover 1204 is driven to move by the telescopic mechanism 7, and the pushing plate 1210 can be driven to move, and when the rectangular thin plate abuts against the first inclined surface 1211 and the side wall of the stopper 1203, the pushing plate 1210 can be pushed to move in the direction away from the support plate 1201, and after the rectangular thin plate passes over the pushing plate 1210, the pushing plate 1210 can move in the direction close to the support plate 1201 under the action of the first spring 304, and the rectangular thin plate can be pressed against the side wall of the support plate 1201 by the pushing plate 1210, and at the same time, the cooling cover 1204 abuts against the side wall of the rectangular thin plate, which is more stable and reliable;

[0043] When the push plate 1210 moves, the baffle 1207 can be driven to move through the first connecting block 1209, the second connecting block 301 and the first connecting plate 1208, and the first spring 304 is compressed, so that the position of the baffle 1207 can be adjusted according to the width of the rectangular thin plate, thereby adjusting the width of the cooling chamber 1206. At the same time, when the second connecting block 301 moves, the first push block 403 can be driven to move through the second sliding plate 402, and the second inclined surface 404 is abutted against the side wall of the first sliding plate 202, thereby pushing the first sliding plate 202 to slide into the fixed cover 201. At the same time, the second spring 504 is compressed, and the circular hole 203 is aligned with the hose 1306 and the connecting pipe 1305, so that the opening range of the opening and closing mechanism 2 can be adjusted according to the height of the thin plate.

[0044] After the rectangular thin plate is clamped and fixed, when the second moving block 602 continues to move, the sleeve 701 can slide along the side wall of the sleeve rod 702, and the third spring 703 is compressed. At this time, the distance between the second moving block 602 and the cooling cover 1204 gradually becomes smaller, which can make the push rod 809 move downward along the inclined groove 808, thereby pushing the second pushing block 805 and the insertion rod 806 to move downward, and insert the insertion rod 806 into the socket 804 for connection. When the second moving block 602 continues to move, it can drive the first moving block 1302 to slide into the liquid storage tank 1301 through the second connecting plate 803 and the third sliding plate 802. At the same time, the fourth spring 812 is gradually compressed. , so that the coolant temporarily stored in the liquid storage tank 1301 can be squeezed, and after passing through the liquid supply pipe 1304 and the connecting pipe 1305, it enters the cooling chamber 1206 after the opening of the opening and closing mechanism 2 and the hose 1306. During welding, the rectangular thin plate can be cooled to avoid welding deformation, etc., to ensure the quality of welding, and the area of ​​the cooling liquid introduced into the cooling cover 1204 can be adaptively adjusted according to the size of the rectangular thin plate, to ensure that the cooling liquid can be introduced into the part where the cooling cover 1204 and the rectangular thin plate are in contact, while the cooling liquid will not be introduced into other parts, which can improve the cooling efficiency and effect, thereby ensuring the quality of welding, and can improve the utilization rate of the cooling liquid;

[0045] After welding is completed, the second moving block 602 is gradually reset by the moving module 603. At this time, the third spring 703 is gradually reset, so that the distance between the second moving block 602 and the cooling cover 1204 is gradually increased, so that the push rod 809 can slide downward along the inclined groove 808, and can push the second moving block 602 and the second connecting plate 803 to move upward and withdraw from the socket 804. At this time, the first moving block 1302 can be moved and reset in the direction away from the liquid storage tank 1301 under the action of the fourth spring 812, so that the coolant in the cooling chamber 1206 can be drawn back into the liquid storage tank 1301, and the cooling operation is performed under the action of the refrigerator 1303. When the cooling cover 1204 is detached from the rectangular thin plate, the welded hardware parts can be removed from between the push plate 1210 and the support plate 1201.
