[0025] ​Before use, the height of the workpiece fixing table 2 can be adjusted according to the thickness of the long plate workpiece to be welded, when adjusting, first loosen the screw on the fixing table mounting seat 103, then start the lifting adjusting hydraulic cylinder 102 to adjust, when adjusting to the appropriate position, tighten the screw on the fixing table mounting seat 103 to fix the height of the workpiece fixing table 2;

[0026] The workpiece fixing structure 3 is symmetrically arranged on the top of the main support 1, the workpiece fixing structure 3 comprises a pressing plate mounting beam 301 and a pressing plate 302, the pressing plate 302 is fixedly installed on the inner side of the pressing plate mounting beam 301, and the tail end of the pressing plate 302 is inclined downward; the left and right ends of the pressing plate mounting beam 301 are both provided with a rotary connecting arm 303, the rotary connecting arm 303 is rotatably connected with the top of a rotary connecting seat 304 through a rotating shaft; the outer side of the rotary connecting seat 304 at the rear side of the main support 1 is further connected with a conductive column 305 through a bolt, and the conductive column 305 is made of rubber material;

[0027] The left and right ends of the main support 1 are also rotatably provided with a conductive plate 4, the side of the conductive plate 4 is rotatably connected with a first bearing seat 401 through a rotating shaft and a bearing, and the inner side of the conductive plate 4 is also provided with a hooking part 402, the hooking part 402 is arranged in correspondence with the conductive column 305, the outer side of the hooking part 402 is rotatably connected with the output shaft of an opening and closing hydraulic cylinder 403 through a pin shaft, the bottom of the opening and closing hydraulic cylinder 403 is rotatably connected with a hydraulic cylinder seat 404, and the hydraulic cylinder seat 404 is fixedly installed on the bottom of the main support 1;

[0028] In use, the long plate workpiece to be welded is placed on the workpiece fixing table 2, then the opening and closing hydraulic cylinder 403 is actuated to drive the conductive plate 4 to rotate, then the hooking part 402 of the conductive plate 4 contacts the conductive column 305, and then the conductive column 305 drives the workpiece fixing structure 3 to rotate, and the pressing plate 302 of the workpiece fixing structure 3 inclines downward to press the long plate workpiece to be welded;

[0029] The conductive column 305 made of rubber material is adopted in the scheme, which can reduce the direct impact of the conductive plate 4 on the conductive column 305 when the opening and closing hydraulic cylinder 403 is actuated, and can also reduce the deformation of the workpiece caused by the pressing plate 302 extruding the workpiece when the actuating amplitude of the opening and closing hydraulic cylinder 403 is too large;
