Until the linkage rod touches the limit rod, the limit rod moves upward and stretches the tension spring through the connecting frame. After the linkage rod moves to the right and separates from the limit rod, the limit rod moves downward under the action of the tension spring to limit the linkage rod. At this time, the flipping of the transformer core is realized; 4. When the moving plate moves to the left, the flipped transformer core is welded by the welding torch, thereby realizing the welding of both sides of the transformer core and improving the welding efficiency; 5. The moving plate continues to move to the left, so that the push block driven by the support rod touches the abutting block, causing the abutting block, the connecting frame and the limit rod to move upward. After the limit rod moves upward and separates from the linkage rod, under the release action of the spring, the slide rod drives the linkage rod to move leftward and reset, thereby realizing the flipping and resetting of the clamping seat; 6. While the reciprocating lead screw rotates, the rotating shaft drives the fan to rotate through the action of the driving gear and the driven gear, so that the dust generated during welding is adsorbed through the suction hood, enters the cylinder through the through pipe and the telescopic hose, and is then discharged to the external purification equipment through the discharge pipe.

[0029] Working principle: When in use, the first motor 16 is started to rotate the bidirectional screw rod 17, so that the two slides 3 move toward each other, so that the slides 3 drive the mounting shaft 4 and the clamping seat 5 to move synchronously, and then the transformer core is clamped and fixed; When the slide plate 3 moves, the connecting plate 36 and the hollow tube 33 are driven to move synchronously through the connecting rod 37, so that the slide rail 35 slides relative to the slide groove 34; Then, the second motor 20 is started to rotate the reciprocating screw 19, firstly, the moving plate 6 drives the support plate 7, the electric telescopic rod 15 and the welding gun 9 to move to the right, and the transformer core is welded by the welding gun 9; While the moving plate 6 and the supporting plate 7 move to the right, the moving plate 6 drives the straight rod 45 and the pushing block 46 to move to the right. When the supporting plate 7 moves to the right, it will contact the linkage rod 28, causing the linkage rod 28 to move to the right, and the sliding rod 27 drives the side plate 47 to move to the right to compress the spring 48. At the same time, the linkage rod 28 moves to the right and drives the rack 29 to move synchronously, so that the linkage gear 30 engaged with the rack 29 drives the rotating rod 31 to rotate, and through the relative limiting effect of the slide rail 35 and the chute 34, the hollow tube 33 is driven to rotate synchronously, thereby driving the mounting shaft 4, the clamping seat 5 and the transformer core to rotate synchronously through the driving of the driving pulley 38, the belt 39 and the driven pulley 40; After the linkage rod 28 moves to the right and contacts the limiting rod 42, it will push the limiting rod 42 to move upward, causing the connecting frame 43 to move upward synchronously and stretch the tension spring 44. After the linkage rod 28 moves to the right and separates from the limiting rod 42, under the pulling action of the tension spring 44, the connecting frame 43 drives the limiting rod 42 to move downward, so that the limiting rod 42 limits and fixes the linkage rod 28. At this time, the position of the linkage rod 28 causes the clamping seat 5 and the clamped transformer core to flip 180°; Subsequently, when the reciprocating lead screw 19 continues to rotate, the moving plate 6 drives the supporting plate 7, the electric telescopic rod 15 and the welding torch 9 to move to the left. At this time, the other side of the transformer core is welded by the welding torch 9; When the moving plate 6 moves to the left, the straight rod 45 and the pushing block 46 move to the left until the pushing block 46 contacts the abutting block 8, causing the abutting block 8 to move upward, so that the connecting frame 43 drives the limiting rod 42 to move upward. After the limiting rod 42 moves upward and separates from the linkage rod 28, under the releasing action of the spring 48, the side plate 47 drives the sliding rod 27 and the linkage rod 28 to reset and move. The reset movement of the linkage rod 28 will cause the clamping seat 5 to reset and flip for subsequent use; While the reciprocating lead screw 19 rotates, it drives the driving gear 23 to rotate, so that the driven gear 24 engaged with the driving gear 23 drives the rotating shaft 25 and the fan 26 to rotate synchronously, so that the smoke generated during welding is sucked into the through pipe 12 through the suction hood 13, enters the cylinder body 10 through the telescopic hose 11, and then is discharged through the discharge pipe 14. The discharge pipe 14 is externally connected to an air purification device to realize the treatment of the smoke.
