The side of the support rod 27 away from the workbench 1 is fixedly connected to a gear box 28. The end of the rotating rod 24 away from the workbench 1 is fixedly connected to a gear 29, and the gear 29 rotates in the gear box 28. The outer wall of the gear 29 passes through the concave annular plate 8 and is meshed with the annular rack 10.

[0023] The above scheme is adopted: turn on the motor 2 to make the rotating shaft 3 drive the connecting plate 4 to rotate and drive the placement frame 1 5 to rotate at the same time.

At the same time, when the rotating shaft 3 rotates, it will drive the synchronous wheel 25 to rotate and drive the rotating rod 24 to rotate through the synchronous belt 26. When the rotating rod 24 rotates, the gear 29 will engage with the annular rack 10, so that the annular plate 9 rotates in the concave annular plate 8. When the annular plate 9 rotates, it drives the placement frame 2 11 and the upper half 13 of the oil tank placed inside the placement frame 2 11 to rotate.

When the placing frame 1 5 rotates, the L-shaped support rod 21 and the limiting slide rod 22 will be driven to slide in the slide groove 20. When the L-shaped support rod 21 and the limiting slide rod 22 slide in the slide groove 20, the L-shaped support rod 21 drives the limiting plate 16 and the second mounting plate 17 to slide in the limiting groove 14, so that the spring 15 is compressed, so that the welding head 18 of the lower part 12 of the oil tank and the upper part 13 of the oil tank are always attached to the welding position of the lower part 12 of the oil tank and the upper part 13 of the oil tank when they rotate, avoiding the problem of manual operation of turning over the oil tank after welding on one side is completed, which is a cumbersome operation. After the welding of one side of the fuel tank is completed, the welding side will reach the position of the grinding head 23 through the rotation of the placing frame 1 5 and the placing frame 2 11, and then the grinding head 23 is turned on to grind the welded part. Through the arrangement of the above-mentioned limiting groove 14, spring 15, limiting plate 16, mounting plate 2 17, slide groove 20, L-shaped support rod 21 and limiting slide rod 22, the grinding head 23 can always fit the welding part between the lower half 12 of the fuel tank and the upper half 13 of the fuel tank, thereby reducing the problem of removing the fuel tank for grinding after the welding of the fuel tank is completed, thereby improving the work efficiency. The dust generated during grinding can be blocked by the material blocking frame 30, and the dust under the blocking will fall to the top of the workbench 1. When the placement frame 5 rotates, the cleaning rod 33 will be driven to rotate. Through the rotation of the cleaning rod 33, the dust on the top of the workbench 1 can be cleaned into the material discharge trough 31 and fall into the collection box 32 through the material discharge trough 31 for unified cleaning.
