[0037] This embodiment provides a welding auxiliary device. Figure 1 to Figure 2 As shown, the welding auxiliary device includes a support platform 1, a support 2 and a movable mechanism 3, wherein the support platform 1 is arranged to rotate along its own axis, the support 2 is arranged on one side of the support platform 1, and the movable mechanism 3 includes a first movable component 31 and a second movable component 32. Among them, a welding gun 4 is arranged on the first movable component 31, and the welding gun 4 is located above the support platform 1. The first movable component 31 is used to drive the welding gun 4 to approach or move away from the support platform 1. The second movable component 32 can drive the first movable component 31 to move along an arc trajectory, so that when the support net is fixed on the support platform 1, the arc movement trajectory of the welding gun 4 is concentric with the support net.

[0038] In this embodiment, when used for welding the support mesh and the pole frame, the support mesh and the pole frame to be welded are placed on the support table 1 and put in place. Since the connection trajectory of all target welding points on the support mesh is a circle with the same center as the support mesh, the moving trajectory of the welding gun 4 is set to be cocentric with the support mesh. When the support table 1 rotates or the welding gun 4 moves, the welding gun 4 can be aimed at multiple target welding points in sequence without adjusting the position of the support mesh.

[0039] Specifically, when welding is performed, the support table 1 is first rotated to move the welding area of ​​the support net to the area corresponding to the welding gun 4, and the welding area of ​​the support net is distributed in an arc shape with multiple target welding points. Then, the second moving component 32 drives the first moving component 31 to move along the arc trajectory, so that the welding gun 4 is fine-tuned along the arc trajectory. The arc trajectory is concentric with the arc trajectory line formed by the multiple target welding points, so that the welding gun 4 can be aligned with multiple target welding points in sequence during the movement. Specifically, when the welding gun 4 is aligned with a target welding point, the first moving component 31 drives the welding gun 4 to approach the support net to weld the target welding point, and when the welding is completed, the first moving component 31 drives the welding gun 4 away from the support net. When all the target welding points on a welding area are welded, the support table 1 is continued to be rotated, and the next welding area is moved to the area corresponding to the welding gun 4, and then the welding gun 4 is driven by the second moving component 32 to continue the welding work. Through the rotation of the support table 1 and the cooperation of the movement of the welding gun 4 along the arc trajectory, the successful welding of all the target welding points on the circumference of the support net can be finally achieved.
