[0021] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments. However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0022] Embodiment

[0023] Please refer to Figures 1-4 As shown, the present utility model provides an adjustable welding base. The adjacent surfaces of the first magnet bar 10 and the second magnet bar 11 are opposite magnetic poles, so that the first magnet bar 10 and the second magnet bar 11 can be attracted and fixed to each other. A plurality of limiting holes 14 are formed in the workbench 1, and the plurality of limiting holes 14 are distributed in a circular array. A cross plate 15 is fixedly connected to the turntable 3. A vertical rod 16 is inserted through the cross plate 15. One end of the vertical rod 16 is fixedly connected to a fixing plate 17. A spring 18 is fixedly connected between the fixing plate 17 and the cross plate 15. The other end of the vertical rod 16 is fixedly connected to a limiting block 19. Support legs 20 are fixedly connected to the lower end corners of the workbench 1.

[0024] When in use, by pulling the fixing plate 17, the fixing plate 17 drives the vertical rod 16 and the limiting block 19 at one end of the vertical rod 16 to move upward. At the same time, the spring 18 extends until the limiting block 19 completely leaves the limiting hole 14 and no longer limits and fixes the turntable 3. Under the action of the rotating shaft 2, the turntable 3 is rotated so that the turntable 3 drives the workpiece to rotate together until it rotates to a suitable angle. Then, stop pulling the fixing plate 17. The fixing plate 17 drives the vertical rod 16 and the limiting block 19 to move downward under the elastic force of the spring 18, and the limiting block 19 is inserted into the limiting hole 14 again to fix the turntable 3. Through this device, the levelness of the turntable 3 can be well adjusted, avoiding the need for welders to rotate around the workpiece when welding the workpiece.

[0025] As a further implementation manner of this embodiment, as Figures 1-6As shown in the figure, a rotating shaft 2 is provided at the upper end of the workbench 1. The upper end of the rotating shaft 2 is fixedly connected with a turntable 3. A limiting groove 21 is formed in the turntable 3. A rotating handle 4 is arranged on one side of the turntable 3. One end of the rotating handle 4 penetrates through the turntable 3 and extends into the limiting groove 21 and is fixedly connected with a bidirectional lead screw 5. One end of the bidirectional lead screw 5 is rotatably connected with the turntable 3. A pair of limiting plates 6 are threadedly connected to the bidirectional lead screw 5. The limiting groove 21 can play a role in limiting the limiting plates 6. A placing block 7 is fixedly connected to the upper end of the limiting plate 6. A placing groove 22 is formed in the placing block 7. A limiting column 8 is fixedly connected in the placing groove 22. The limiting column 8 penetrates through the connecting block 9. At the same time, the placing groove 22 in the placing block 7 can play a certain role in limiting the connecting block 9. A pair of first magnet bars 10 are arranged in the placing groove 22. A pair of second magnet bars 11 are arranged on one side of the connecting block 9. An arc-shaped clamping plate 12 and a square clamping plate 13 are respectively arranged on the two connecting blocks 9.

[0026] When in use, when it is necessary to fix the arc-shaped workpiece, the two connecting blocks 9 with the arc-shaped clamping plates 12 can be placed into the placing groove 22 in the placing block 7, and the limiting column 8 penetrates through the through hole in the connecting block 9. The placing groove 22 in the placing block 7 can also play a certain role in limiting the connecting block 9. At the same time, a pair of first magnet bars 10 in the placing groove 22 and a pair of second magnet bars 11 on the connecting block 9 can be attracted and fixed to finally realize the installation of the arc-shaped clamping plate 12. When it is necessary to fix the square workpiece, the arc-shaped clamping plate 12 and the connecting block 9 can be pulled upward to separate the second magnet bar 11 at the lower end of the connecting block 9 from the first magnet bar 10, so that the arc-shaped clamping plate 12 can be disassembled from the placing block 7, and then the square clamping plate 13 can be installed (the installation methods of the arc-shaped clamping plate 12 and the square clamping plate 13 are completely the same and will not be elaborated). Through this device, different-shaped clamping plates can be replaced well according to the shape of the tool, so that the workpiece can be fixed better.

[0027] Specific working principle: During use, when it is necessary to fix an arc-shaped workpiece, the two connecting blocks 9 with arc-shaped clamping plates 12 can be placed into the placement grooves 22 in the placement block 7, and the limit posts 8 penetrate through the through holes on the connecting blocks 9. Also, the placement grooves 22 on the placement block 7 can play a certain limiting role on the connecting blocks 9. At the same time, a pair of first magnet bars 10 in the placement grooves 22 and a pair of second magnet bars 11 on the connecting blocks 9 can attract and fix each other, thus finally realizing the installation of the arc-shaped clamping plates 12; when it is necessary to fix a square workpiece, the arc-shaped clamping plates 12 and the connecting blocks 9 can be pulled upward, and the second magnet bars 11 at the lower ends of the connecting blocks 9 can be separated from the first magnet bars 10, so that the arc-shaped clamping plates 12 can be detached from the placement block 7, and then the square clamping plates 13 can be installed (the installation methods of the arc-shaped clamping plates 12 and the square clamping plates 13 are exactly the same and will not be elaborated here). After the corresponding clamping plates are installed, the workpiece is placed on the upper end of the turntable 3, and then the rotary handle 4 is rotated to drive the bidirectional lead screw 5 to rotate. The rotation of the bidirectional lead screw 5 drives the two limit plates 6 to move, and the limit plates 6 can move more stably under the limiting action of the limit grooves 21. The movement of the limit plates 6 drives the clamping plates to fix the workpiece, facilitating subsequent welding operations on the workpiece. With this device, different-shaped clamping plates can be replaced well according to the shape of the tool, so as to better fix the workpiece.
