[0039] The principle of this utility model is:

[0040] When the utility model is in use, each plate of the box workpiece 9 is first spot-welded into shape (to ensure that there is no cracking during subsequent welding operations), and then hoisted between the first flipping mechanism 76 and the second flipping mechanism 84 by a hoisting device such as a crane. At this time, the operator stands on the first flipping mechanism 76 and pulls one end of the box workpiece 9 to the clamp 75. After the clamp 75 clamps one end of the box workpiece 9, tighten the locking bolt 755 to achieve clamping and fixation of one end of the box workpiece 9.

[0041] At this time, the second flip mechanism 84 is controlled to move so that the second flip clamp 83 is in close contact with the other end of the box workpiece 9, so that the entire box workpiece 9 can be clamped and fixed. At this time, the welding robot 6 can be controlled to perform welding operations on the box workpiece 9. During the welding operation, by controlling the first flip clamp 74 and the second flip clamp 83 to rotate synchronously, welding operations on different welding parts can be realized, thereby completing the welding operation of the entire box workpiece 9.

[0042] It should be noted that the various walking mechanisms involved in the present invention have a relatively simple working principle and the control process involved is also an existing mature technology (the control process needs to be coordinated with various limit sensors and travel switches, which are not difficult to understand for those skilled in the art and are shown in the accompanying drawings of the embodiments but not marked), so they will not be elaborated here. In addition, the present invention also involves a welding wire barrel 28, a balancer 3, a welding wire feeding device 4 and a welding robot 6, which are all mature technologies in this field and are used to continuously and stably feed the welding wire to the welding robot 6, so they will not be elaborated thereon.

[0043] It should also be noted that the present invention involves a clamp 75 in which the mounting seat 751 and the clamping portion 754 are hinged in order to facilitate actual operations. During actual lifting operations, it is difficult to accurately restrict the box workpiece 9 to the same position and keep the state unchanged. The hinged connection makes it easier and more efficient for the clamp 75 to clamp the box workpiece 9. In addition, a locking portion 757 and an engaging portion 758 are provided in the clamp 75, which can be changed accordingly according to the actual shape of the box workpiece 9 so as to match the workpiece to be processed.
