[0021] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0022] First, combine Figures 1 to 4 An arc welding device with a preheating function according to an embodiment of the utility model is described, which is used in the field of arc welding technology and has a wide range of application scenarios.

[0023] like Figures 1 to 4 As shown, the arc welding device with preheating function of the embodiment of the utility model comprises:

[0024] Robot 1;

[0025] A quick-change plate 2, the robot side of the quick-change plate 2 is connected to the output end of the manipulator 1;

[0026] An arc welding gun 3, one end of which is connected to the output end of the manipulator 1, and the arc welding gun 3 is used to weld the product;

[0027] A preheating gun 4 , one end of which is connected to the tool side of the quick-change plate 2 , so that the preheating gun 4 can be quickly separated from the manipulator 1 .

[0028] Further, if Figure 2 As shown, in this embodiment, it also includes: a connecting plate 5, a preheating gun 4 is connected to the tool side of the quick-change disk 2 through the connecting plate 5, and after the preheating is completed, the manipulator 1 drives the connecting plate 5 to insert into the external fixing seat, so that the preheating gun 4 is separated from the manipulator 1, and then the manipulator 1 drives the arc welding gun 3 to perform welding work.

[0029] Further, if Figure 2 As shown, in this embodiment, the connecting plate 5 is provided with a first through hole 51 and a second through hole 52;

[0030] One end of the preheating gun 4 is fixed in the first through hole 51;

[0031] The tool side of the quick-change disc 2 is fixedly connected to the connecting plate 5 via the second through hole 52 .

[0032] Further, if Figure 2 As shown, in this embodiment, the width of the lower end of the connecting plate 5 is smaller than that of the upper end, and a limiting step 53 is provided to facilitate insertion into the external fixing seat and to play a limiting role.
