[0002] Steel plate is the flat plate steel material that is casted with molten steel and is pressed after cooling, and in the process of processing the steel plate, it is often necessary to weld and connect two steel plates, which requires the two steel plates to be assembled together and then welded along the gap.

[0003] A clamping device for stainless steel plate welding is disclosed in Chinese patent with publication number CN215034906U, which comprises a steel plate body, a rotating hand wheel, a bottom plate, and a second support block. The bottom plate has grooves on both sides, and there are four grooves on the bottom plate. The second support block is fixedly installed on the top of the bottom plate through screws, and there are four second support blocks on the bottom plate. The top of the second support block is movably provided with a gas cylinder through a shaft, and one end of the gas cylinder is connected with a connecting rod through a shaft. The utility model places the bottom plate on the machine table, then passes the fixed block through the gap on the machine table, then passes the threaded rod through the groove and screws it into the screw hole in the fixed block, and then rotates the rotating hand wheel to fix the device on the machine table, achieving the purpose of fixing the device conveniently.

[0004] However, it still has the following disadvantages: the device controls the extension of the gas cylinder to make the pressing rod downwardly press and position the steel plate, but the device is not convenient for aligning the welding position of the two steel plates, and it is not convenient for feeding and discharging the steel plate. Therefore, we propose a positioning and clamping device for welding to solve this problem. UTILITY MODEL CONTENTS
