The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model embodiment provides a mobile welding machine, such as Figure 1-4 As shown, it includes a fixing frame 1, the cross section of the fixing frame 1 is a rectangular frame structure, the bottom of the fixing frame 1 is fixedly connected to the supporting legs 2 by bolts, and there are four supporting legs 2, which are symmetrically arranged at the bottom of the fixing frame 1, and the bottom ends of the supporting legs 2 are fixedly connected to the universal walking wheels 3 by bolts, and the top of the fixing frame 1 is fixedly connected to the first hydraulic cylinder 4 and the second hydraulic cylinder 5 by bolts, the first hydraulic cylinder 4 is located on one side of the second hydraulic cylinder 5, and there are four first hydraulic cylinders 4 and four second hydraulic cylinders 5, and the four first hydraulic cylinders 4 and the four second hydraulic cylinders 5 are symmetrically arranged at the top of the fixing frame 1, and the first hydraulic cylinder 4 and the second hydraulic cylinder 5 are both connected through the output ends on one side thereof. A lifting plate 6 is fixedly connected, and a support plate 7 is fixedly connected to the top of the lifting plate 6 by bolts. A third hydraulic cylinder 8 is fixedly connected to the outer wall of one side of the support plate 7 by bolts. The third hydraulic cylinder 8 is fixedly connected to a clamping plate 9 through an output end on one side. A fixing plate 10 is fixedly connected to the top center of the fixing frame 1 by bolts. The cross section of the fixing plate 10 is a U-shaped structure. A fourth hydraulic cylinder 11 is fixedly connected to the top center of the fixing plate 10 by bolts. The fourth hydraulic cylinder 11 is fixedly connected to a dual-axis mobile platform 12 through an output end on one side. The dual-axis mobile platform 12 adopts a cross slide. The dual-axis mobile platform 12 is fixedly connected to a welding head 13 through an output end on one side.

[0022] It should be noted that, since the existing welding machine cannot move when processing large workpieces to be welded, the welding work needs to move the large workpieces to be welded. This process is very inconvenient and requires a lot of manpower and material resources. The large workpieces to be welded need to be moved to a high place, which is very inconvenient. In this embodiment, after the two lifting plates 6 are lowered to a low point, the two workpieces to be welded only need to be moved upward a short distance, which is very convenient for the staff to use, saves time and effort, and reduces the staff's carrying intensity. By clamping and fixing the workpieces to be welded on the lifting plate 6, the stability of the workpieces to be welded during welding can be guaranteed, thereby ensuring the welding accuracy. By moving the welding machine to one side of the workpiece to be welded, the horizontal distance of the workpiece to be welded can be further reduced, which is more labor-saving and convenient.

[0023] Specifically, in this embodiment, this scheme mainly includes a universal walking wheel 3, by the rotation of the universal walking wheel 3, the welding machine can be moved to one side of the workpiece to be welded, and the universal walking wheel 3 is locked. At this time, the staff moves the workpiece to be welded upward to the top of the lifting plate 6 and then puts it down, and the welding points of the two workpieces to be welded are connected together. The third hydraulic cylinder 8 drives the clamping plate 9 to move through the output end on one side thereof, and the two clamping plates 9 clamp the workpiece to be welded and fix it. The first hydraulic cylinder 4 and the second hydraulic cylinder 5 respectively drive the two lifting plates 6 to move upward synchronously through the output ends on one side thereof. After the lifting plate 6 lifts the workpiece to be welded to a high place, the fourth hydraulic cylinder 11 drives the dual-axis movable platform 12 to move downward through the output end on one side thereof, and the dual-axis movable platform 12 drives the welding head 13 to move through the output end on one side thereof, and the welding head 13 performs welding operations on the workpiece to be welded.

[0024] In a further preferred embodiment of the present invention, Figure 3 As shown, the support plate 7 and the clamping plate 9 are both perpendicular to the lifting plate 6 .

[0025] In this embodiment, it can be ensured that the clamping plate 9 can stably clamp and fix the plate-shaped workpiece to be welded.

[0026] In a further preferred embodiment of the present invention, Figure 1 and Figure 4 As shown, a guide rod is provided on the top of the dual-axis movable platform 12 , and the guide rod passes through the fixed frame 1 .

[0027] In this embodiment, the stability of the lifting and lowering of the dual-axis movable platform 12 can be ensured, and the dual-axis movable platform 12 can be prevented from tilting.
