An electric turntable 9 is rotatably connected to the inner wall of the first moving plate 8. An electric claw 10 is arranged on the right side of the electric turntable 9. When welding, the welding part is placed on the top of the support table 7. At this time, the motor 4 is started. The start of the motor 4 drives the bidirectional lead screw 6 to rotate. The rotation of the bidirectional lead screw 6 contacts the thread on the surface of the bidirectional lead screw 6 through the slider inside the first moving plate 8, and generates a squeezing force to make the first moving plate 8 move to the right. The rightward movement of the first moving plate 8 drives the electric turntable 9 to move to the right. The rightward movement of the electric turntable 9 drives the electric claw 10 to move, so as to apply pressure to both sides of the welding part. Then, the welding part is clamped by the electric claw 10, and thus the welding part can be firmly fixed to improve the accuracy during the welding process. At the same time, after the welding part is fixed, the electric turntable 9 is started and will rotate. The rotation of the electric turntable 9 drives the electric claw 10 to rotate, so as to flip and adjust the welding part, enabling the flexible adjustment of the workpiece angle, so that the welding gun 3 can be aligned with the weld seam at a suitable angle. A sloping plate 11 is fixedly connected to the front part of the first moving plate 8. A slag cleaning device 14 for preventing slag accumulation is arranged on the inner wall of the welding table 1.

A fixing plate 13 is fixedly connected to the surface of the lifting plate 12. At the same time, the movement of the bidirectional lead screw 6 drives the sloping plate 11 to move. During the movement of the sloping plate 11, it will contact the lifting plate 12 and generate a squeezing force on the lifting plate 12, making the lifting plate 12 move upward. The upward movement of the lifting plate 12 drives the fixing plate 13 to move upward. The upward movement of the fixing plate 13 will push the workpiece to a suitable height, so as to automatically adapt to the size of the workpiece through the electric claw 10, adjust to a suitable angle, and the movement of the first moving plate 8 applies a force to gather the workpiece towards the middle, realizing the automatic fixed clamping of the workpiece, reducing the intervention of workers in welding, and improving the work efficiency of workers.

The movement of the scraping plate 142 drives the movement of the connecting plate 143, and the movement of the connecting plate 143 drives the movement of the knocking rod 144. During the movement of the knocking rod 144, it will contact the first convex block 145 and be forced to move upward by the upward extrusion force of the first convex block 145. After the knocking rod 144 passes over the first convex block 145, the knocking rod 144 will move downward through the spring, thereby generating vibration on the surface of the hollow plate 141, enabling the welding slag to fall off due to vibration, ensuring that the hollow plate 141 remains clean, and preventing the normal operation of the device from being affected by the accumulation of welding slag. A first reciprocating lead screw 146 is rotatably connected to the inner wall of the scraping plate 142, a transmission wheel 147 is fixedly connected to the circumferential surface of the first reciprocating lead screw 146, a pushing plate 148 is movably connected to the circumferential surface of the first reciprocating lead screw 146.

At the same time, the movement of the scraping plate 142 drives the movement of the first reciprocating lead screw 146, the movement of the first reciprocating lead screw 146 drives the movement of the transmission wheel 147. During the movement of the transmission wheel 147, it will contact the top of the hollow plate 141 and drive the first reciprocating lead screw 146 to rotate through friction. The rotation of the first reciprocating lead screw 146 drives the pushing plate 148 to reciprocate, thereby pushing the scraped welding slag into the collection box 149 through the gaps of the hollow plate 141, and then realizing the automatic collection and cleaning of the welding slag, reducing the labor intensity of workers and improving work efficiency. The top of the hollow plate 141 is in contact with the bottom of the inclined plate 11, the top of the hollow plate 141 is in contact with the bottom of the lifting plate 12, the bottom of the first moving plate 8 is in contact with the top of the hollow plate 141, the top of the hollow plate 141 is in contact with the bottom of the knocking rod 144, and the knocking rod 144 is used to generate vibration on the surface of the hollow plate 141.

The movement of the scraping plate 142 will scrape off the welding slag falling on the surface of the hollow plate 141, enabling automatic cleaning of the welding slag during welding.

The rotation of the first reciprocating lead screw 146 drives the pushing plate 148 to reciprocate, enabling automatic collection of the welding slag and reducing the labor intensity of workers.

[0016] Working principle: When welding, place the welding piece on the top of the support table 7. At this time, the motor 4 starts. The start of the motor 4 drives the bidirectional lead screw 6 to rotate. The rotation of the bidirectional lead screw 6 contacts the threads on the surface of the bidirectional lead screw 6 through the slider inside the first moving plate 8, and generates a squeezing force that causes the first moving plate 8 to move to the right. The rightward movement of the first moving plate 8 drives the electric turntable 9 to move to the right. The rightward movement of the electric turntable 9 drives the electric claw 10 to move, so that pressure can be applied to both sides of the welding piece. Subsequently, the welding piece is clamped by the electric claw 10, and then the welding piece can be firmly fixed to improve the accuracy during the welding process. At the same time, after the welding piece is fixed, the electric turntable 9 starts and rotates. The rotation of the electric turntable 9 drives the electric claw 10 to rotate, so that the welding piece can be flipped and adjusted, enabling the flexible adjustment of the workpiece angle, so that the welding gun 3 can be aligned with the weld at a suitable angle. At the same time, the movement of the bidirectional lead screw 6 drives the inclined plate 11 to move. During the movement of the inclined plate 11, it contacts the lifting plate 12 and generates a squeezing force on the lifting plate 12, causing the lifting plate 12 to move upward. The upward movement of the lifting plate 12 drives the fixing plate 13 to move upward. The upward movement of the fixing plate 13 pushes the workpiece to a suitable height. Thus, through the electric claw 10, it automatically adapts to the size of the workpiece, adjusts to a suitable angle, and the first moving plate 8 moves to apply a force that converges the workpiece towards the middle, realizing the automatic fixed clamping of the workpiece, reducing the intervention of workers in welding, and improving the work efficiency of workers. After the workpiece is fixed, the lifting plate 12 moves down along the inclined surface of the inclined plate 11 to avoid affecting the flipping of the workpiece.

[0017] Overall working principle: When welding, the welding piece is clamped by the electric claw 10, which can quickly fix the workpiece and improve the accuracy in welding. The rotation of the electric turntable 9 drives the electric claw 10 to rotate, which can adjust and flip the workpiece, enabling the part to be welded of the workpiece to always be in the best welding position.

[0018] During welding, the inclined plate 11 moves to drive the scraper 142 to move. The movement of the scraper 142 will scrape off the welding slag that has fallen on the surface of the hollow plate 141, preventing excessive accumulation of welding slag. The movement of the scraper 142 drives the connecting plate 143 to move, and the movement of the connecting plate 143 drives the knocking rod 144 to move. During the movement of the knocking rod 144, it will contact the first convex block 145 and be forced to move upward by the upward extrusion force of the first convex block 145. After the knocking rod 144 passes over the first convex block 145, the knocking rod 144 will move downward through the spring, thereby generating vibration on the surface of the hollow plate 141, enabling the welding slag to fall off due to the vibration, ensuring that the hollow plate 141 remains clean, avoiding the normal operation of the device being affected by the accumulation of welding slag. At the same time, the movement of the scraper 142 drives the first reciprocating lead screw 146 to move, and the movement of the first reciprocating lead screw 146 drives the transmission wheel 147 to move. During the movement of the transmission wheel 147, it will contact the top of the hollow plate 141 and drive the first reciprocating lead screw 146 to rotate through friction. The rotation of the first reciprocating lead screw 146 drives the push plate 148 to reciprocate, thereby pushing the scraped welding slag through the gaps of the hollow plate 141 into the collection box 149, and further realizing the automatic collection and cleaning of the welding slag, reducing the labor intensity of workers and improving work efficiency.

[0019] Overall working principle: The movement of the scraper 142 will scrape off the welding slag that has fallen on the surface of the hollow plate 141, enabling the automatic cleaning of the welding slag during welding. The knocking rod 144 will move downward through the spring, generating vibration on the surface of the hollow plate 141 to improve the slag removal effect.
