[0002] Tooling is an important device used to ensure relative size and position during component processing. In light aircraft, the wing support frame is the connecting part between the wing and the fuselage. The frame is welded and the curvature of the frame needs to be accurately fixed so that no deviation occurs when the wing panel is installed, causing unevenness of the wing.

[0003] However, most existing welding tools directly use local materials to weld a support frame for fixation, which results in large errors, causing the curvature of the wing support frame to be not smooth enough, and deviations to occur when installing the wing panel, causing the wing to be uneven, affecting wind resistance. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model proposes a welding tool, which effectively solves the problem that the large error of the welding tool causes the large error of the curvature of the wing support frame, thus affecting the assembly of the wing.

[0005] The technical solution adopted by the utility model is as follows: A welding tool proposed by the utility model includes a support seat, a limit groove, a support adjustment curvature structure and a fixed structure, wherein the limit groove is arranged on the support seat, the support adjustment curvature structure is arranged on the support seat, and the fixed structure is arranged on the support adjustment curvature structure. The support adjustment curvature structure includes a hydraulic telescopic column, a rotating seat, a rotating column, a fixed shaft, a limit shaft, an extrusion protrusion and a wrench, the hydraulic telescopic column is fixedly arranged on the support seat, the rotating seat is fixedly arranged on the hydraulic telescopic column, the rotating column is rotatably arranged on the rotating seat, the fixed shaft penetrates the rotating seat and the rotating column, the limit shaft penetrates the fixed shaft, the extrusion protrusion is rotatably arranged on the limit shaft, and the wrench is fixedly arranged on the extrusion protrusion.

[0006] Preferably, the fixing structure includes a connecting seat, a slot, an extrusion plate and a fixing bolt, the connecting seat is fixed on the rotating column, the slot is fixed on the connecting seat, the extrusion plate is disassembled on the slot, and the fixing bolt passes through the extrusion plate and is threadedly fixed on the slot.

[0007] In order to better achieve the effect of adjusting the curvature, half of the rotating seat is hollowed out and the extrusion protrusion is elliptical.

[0008] In order to achieve the purpose of fixing more quickly, the rotating column is limitedly rotated by the fixed shaft in the rotating seat.

[0009] Furthermore, the connecting seat on the card slot is connected to the rotating column to rotate and adjust the arc.

[0010] In order to achieve the splicing effect, the hydraulic telescopic columns are provided with two groups which are symmetrically arranged.

[0011] The beneficial effects achieved by the utility model using the above structure are as follows: a welding tool proposed in this scheme adjusts the height curvature of a certain section of material supporting the wing support frame through a hydraulic telescopic column, and then adjusts the curvature of the splicing edge through rotating the card slot, thereby achieving precise positioning of the curvature of the wing support frame.

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] like Figure 1 , Figure 2 and Figure 3As shown, a welding tool proposed by the utility model comprises a support seat 1, a limiting groove 2, a support and adjustment curvature structure 3 and a fixed structure 4, the limiting groove 2 is arranged on the support seat 1, the support and adjustment curvature structure 3 is arranged on the support seat 1, the fixed structure 4 is arranged on the support and adjustment curvature structure 3, the support and adjustment curvature structure 3 comprises a hydraulic telescopic column 5, a rotating seat 6, a rotating column 7, a fixed shaft 8, a limiting shaft 9, an extrusion protrusion 10 and a wrench 11, the hydraulic telescopic column 5 is fixedly arranged on the support seat 1, the hydraulic telescopic column 5 is provided with two groups symmetrically arranged, the rotating seat 6 is fixedly arranged on the hydraulic telescopic column 5, half of the rotating seat 6 is hollowed out, the rotating column 7 is rotatably arranged on the rotating seat 6, the fixed shaft 8 penetrates the rotating seat 6 and the rotating column 7, the rotating column 7 is limitedly rotated by the fixed shaft 8 in the rotating seat 6, the limiting shaft 9 penetrates the fixed shaft 8, the extrusion protrusion 10 is rotatably arranged on the limiting shaft 9, the extrusion protrusion 10 is elliptical, and the wrench 11 is fixed on the extrusion protrusion 10.
