The left - right moving module 310 is arranged on the workbench 100, the front - rear moving module 320 is arranged on the left - right moving module 310, and the welding torch assembly is arranged on the front - rear moving module 320. Among them,

[0045] The front - rear moving module 320 drives the welding torch assembly to move and perform welding work on the surface of the product;

[0046] The left - right moving module 310 drives the front - rear moving module 320 to move left and right, so that the welding torch assembly switches positions between adjacent fixtures 200.

[0047] Specifically, after the product is clamped, the control system controls the actions of the front - rear moving module 320 and the left - right moving module 310, so that the welding torch 340 moves to a preset position (i.e., the front end of the welding part of the product). When the welding work starts, the front - rear moving module 320 drives the welding torch assembly to move back and forth, so that the welding torch 340 moves along the welding line of the product and completes the welding action. The whole welding process is fully automatic without manual intervention, thereby improving the welding efficiency, reducing the labor cost, and at the same time ensuring the welding precision.

[0048] Preferably, it further includes a lifting mechanism, which includes:

[0049] A front - rear moving plate 330, which is connected to the guide rail of the front - rear moving module 320, and the front - rear moving module 320 drives the front - rear moving plate 330 to move back and forth;

[0050] A lifting seat 350, which is located on the top of the front - rear moving plate 330 and is connected to the front - rear moving plate 330 through a guide rod. A main lifting cylinder 360 is arranged on the lifting seat 350, and the cylinder shaft of the main lifting cylinder 360 is connected to the front - rear moving plate 330. The lifting of the lifting seat 350 is realized through the main lifting cylinder 360. Among them,

[0051] The welding torch assemblies are arranged on both sides of the lifting seat 350, and the lifting and lowering of the welding torch assemblies are driven synchronously with the lifting and lowering of the lifting seat 350.

[0052] That is to say, the forward and backward movement of the welding torch assemblies is realized by driving the forward and backward movement plate 330 to move forward and backward through the forward and backward movement module 320, so as to drive the lifting seat 350 to move forward and backward. The setting of the lifting mechanism enables the entire welding torch assemblies to lift and lower. When the product on one fixture 200 is welded, the welding torch assemblies rise and move to another fixture 200 through the left and right movement module 310. At the same time, the welded product can be replaced.

[0053] Preferably, the welding torch assembly consists of a welding torch 340 and a position adjustment structure, and the position adjustment of the welding torch 340 is realized through the position adjustment structure.

[0054] Preferably, the position adjustment structure includes:

[0055] A mounting plate 370, which is arranged on the side of the lifting seat 350;

[0056] A multi-stage lifting structure and a left and right adjustment module 400. The multi-stage lifting structure is connected to the mounting plate 370, and the left and right adjustment module 400 is arranged on the multi-stage lifting structure. The left and right movement of the welding torch 340 is realized through the left and right adjustment module 400, and the multi-stage lifting of the welding torch 340 is realized through the multi-stage lifting structure.

[0057] Preferably, the mounting plate 370 is composed of a fixed plate 371, an adjustment plate 372, and an adjustment screw 373. The fixed plate 371 is fixedly installed on the side of the lifting seat 350. The adjustment plate 372 is connected to the fixed plate 371 through a sliding rail and slider mating surface. The adjustment plate 372 is moved forward and backward along the fixed plate 371 through the adjustment screw 373, thereby realizing the fine adjustment of the front and back positions of the welding torch 340.

[0058] Preferably, the multi-stage lifting structure includes:

[0059] A welding torch lifting cylinder 380, which is vertically arranged and connected to the adjustment plate 372;

[0060] A mounting seat 390, which is connected to the cylinder shaft of the welding torch lifting cylinder 380. The left and right adjustment module 400 is horizontally arranged on the mounting seat 390. The welding torch lifting cylinder 380 can drive the mounting seat 390 to lift and lower, thereby adjusting the height position of the welding torch 340, and the left and right adjustment module 400 is used to adjust the left and right positions of the welding torch 340.

When the welding head of the welding torch 340 descends to the surface of the product, the pressure head 430 abuts against the surface of the product. The setting of the pressure head 430 provides a stable supporting force, preventing the welding torch 340 from shaking or shifting during the welding process and ensuring the welding precision.

[0065] In addition, the lifting actions of the multi-stage lifting structure are specifically as follows:

[0066] 1. The first-level lifting adjustment of the welding torch 340 is realized by driving the lifting of the mounting seat 390 through the welding torch lifting cylinder 380;

[0067] 2. The first lifting module 410 is mainly used to adjust the lifting of the pressure head 430, but at the same time drives the second lifting module 420 and the welding torch 340 to lift synchronously, thereby realizing the second-level lifting adjustment of the welding torch 340;

[0068] 3. The second lifting module 420 is used to separately adjust the lifting of the welding torch 340, thereby realizing the third-level lifting adjustment of the welding torch 340.

[0069] Through the multi-stage lifting structure, the position of the welding torch 340 can be adjusted more flexibly, the position adjustment precision of the welding torch 340 can be improved, and thus the welding quality can be improved.

[0070] Preferably, a wire feeder 500 is further included. It is arranged on the top surface of the lifting seat 350. The wire feeding conduit 510 of the wire feeder 500 extends to the location of the welding head of the welding torch 340.
