[0025] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model is further described below in conjunction with embodiments.

[0027] Example: Refer to the attached Figure 1-3 As shown in the figure, a welding device for processing a generator chassis includes a frame 100, the frame 100 is an annular structure and has an annular groove 101 in the middle thereof, and two sliding blocks 111 are slidably connected in the annular groove 101, and a welding gun 110 is fixedly installed on the sliding block 111; specifically, in the actual welding process, the two symmetrically arranged welding guns 110 can both be adjusted in position relative to the annular groove 101, and during the adjustment process, when the welding gun 110 is in an operating state, it can weld the weld positions of two chassis in a spliced ​​state,

[0028] Furthermore, it also includes a fixed rod 120, which is arranged in an arc-shaped structure. The two ends of the fixed rod 120 are respectively fixedly connected to the sliding block 111. It should be noted that in the present application, when the position of one welding gun 110 is moved, the position of the other welding gun 110 can also be adjusted synchronously. Correspondingly, during the welding process, it is necessary to ensure that the welding gun 110 on one side can be stably aligned with the weld, and the other side can also be well aligned with the weld, so as to achieve efficient welding.

[0029] The vertical frame 200 is also included, which is fixedly connected to the frame body 100, and piston tubes 300 are symmetrically fixedly installed on the vertical frame 200, and piston rods are movably connected inside the piston tubes 300, and a clamping plate 310 is fixedly installed on the end of the piston rod, and an air intake pipe 320 is also included, which is fixedly installed on the piston tube 300 and maintained in communication with the inside thereof; the air intake pipes 320 located on the two piston tubes 300 are maintained in communication with the output end of the same external air pump, and during the welding stage, gas is injected into the air intake pipe 320 through an external air pump to drive the clamping plate 310 to achieve treatment The welded chassis is fixed. Before welding, the chassis to be welded is first placed in the middle position of the two clamping plates 310, and the external cylinder is used to inject gas into the piston tube 300 through the air inlet pipe 320. When the piston tube 300 is injected with gas, it can drive the set piston rod to move and fix the position of the chassis. It should be noted that since the same air pump is used to inject gas into the piston tube 300, the movement distance of the corresponding two clamping plates 310 is the same, thereby ensuring that the welding gun 110 can be aligned with the position of the weld.

[0030] The clamping plate 310 is an arc-shaped structure, and a rubber layer is provided on the inner wall of the clamping plate 310, and a limiting shaft 311 is fixedly installed on both sides of the clamping plate 310, and the limiting shaft 311 slides in cooperation with a slide groove provided on the vertical frame 200. In order to ensure the moving trajectory of the clamping plate 310, a limiting shaft 311 is also fixedly installed on both sides of the clamping plate 310, which can slide in the slide groove provided on the vertical frame 200.

[0031] Furthermore, in order to achieve effective cleaning of welding slag during the welding process, the present solution also includes a capsule 210, which is fixedly installed in a slide groove opened on the vertical frame 200, and the capsule 210 is connected to the air outlet 102 opened on the frame 100 through a connecting pipe 211; and when the limit shafts 311 approach each other, they can compress the capsule 210. When the two clamping plates 310 clamp the chassis, the capsule 210 will be compressed. A control valve is provided on the connecting pipe 211. During the welding process, the control valve is opened. On the one hand, the welding slag remaining in the weld after welding can be cleaned, and at the same time, the unwelded part can be effectively cleaned to ensure the welding effect.
