[0022] In this embodiment, the driving mechanism includes a servo motor 13 and a screw rod 14. The servo motor 13 is fixedly arranged inside one end of the base 1. One end of the screw rod 14 is fixedly connected to the output shaft of the servo motor 13. An installation groove is formed inside the other end of the base 1. A slide bar 6 is installed in the installation groove in a limited sliding manner. The slide bar 6 is screwed and installed on the screw rod 14 through a threaded hole formed inside it. The lifting mechanism includes a lifting rod 4 and a connecting rod 7. A fixed rod 3 is fixedly arranged on the top of the base 1. The lifting rod 4 is arranged in a limited sliding manner on the top of the fixed rod 3. The base 1 is in an "L" shape. A chute 16 is formed on the top of the other end of the base 1. A roller 15 is arranged to roll inside the chute 16. One end of the slide bar 6 is fixedly connected to a moving block 5. The connecting rod 7 is movably installed between the top of the moving block 5 and the top end of the lifting rod 4 through a rotating shaft. The servo motor 13 drives the slide bar 6 to slide inside the base 1 through the screwing action of the screw rod 14 and the slide bar 6. The slide bar 6 drives the moving block 5 to move to the right. The roller 15 and the chute 16 are arranged to reduce the friction between the moving block 5 and the base 1.

The through hole 10 provided is convenient for using a fixture to fix the workpiece, and can also directly fix the workpiece with a through hole or a threaded hole. By rotating the arc-shaped plate 17 through the handle 12, the arc-shaped plate 17 drives the limiting block 20 to separate from the fixed block 19, which is convenient for rotating the flipping frame 9 and the workpiece, so as to adjust the inclination angle of the flipping frame 9 and the workpiece.

[0024] When using this liftable welding tooling, the welding tooling is directly placed on the ground through the base 1 and the cross bar 2, which can improve the stability of the welding tooling.

The arc-shaped plate 17 is combined with the fixed ring 8 under the pulling force of the spring 21, and the limiting block 20 is stuck between the fixed blocks 19, which is convenient for limiting the shaft rod 18, so as to fix the turnover frame 9. Place the workpiece on the top of the turnover frame 9, and use a fixture or fix the workpiece by installing bolts inside the through hole. When it is necessary to adjust the height of the workpiece, start the servo motor 13. The servo motor 13 drives the screw rod 14 to rotate inside the installation groove. The screw rod 14 drives the sliding rod 6 to slide inside the installation groove by screwing. And the sliding rod 6 drives the moving block 5 to drive the roller 15 at its bottom to move horizontally on the base 1. The roller 15 rolls inside the chute 16, which can reduce the friction between the moving block 5 and the base 1. At the same time, the moving block 5 squeezes the connecting rod 7 through the rotating shaft, and the connecting rod 7 pushes the lifting rod 4 to slide and rise inside the fixed rod 3. The lifting rod 4 drives the turnover frame 9 and the workpiece to rise through the fixed ring 8 and the shaft rod 18, which is convenient for adjusting the height of the workpiece. Pull the arc-shaped plate 17 to one side through the handle 12. The arc-shaped plate 17 rotates on the fixed ring 8 and drives the limiting block 20, so that the limiting block 20 moves out from between the fixed blocks 19, which can rotate the turnover frame 9 and the workpiece, facilitating the adjustment of the angles of the turnover frame 9 and the workpiece and convenient for welding the workpiece, with high practicability.
