It can be divided into hot-rolled seamless square tubes, cold-drawn seamless square tubes, extruded seamless square tubes and welded square tubes. Welding parts are needed when welding square tubes, and square tube welded parts refer to parts that connect square tubes of different sizes and specifications together through welding processes. At the same time, square tube welded parts are widely used in construction, machinery, automobiles and other fields. Square tube welded parts are an important metal connection part with the characteristics of high strength, good corrosion resistance and convenient construction. Welding tooling is required when processing square tube welded parts.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.
[0024] The utility model provides a technical solution, a welding tool for processing square tube welding parts, including: Figure 1 , Figure 2 , a tube body 1, and a positioning groove 2 arranged at the center of the inner wall of the tube body 1, and plugs 3 are inserted and connected at both ends of the tube body 1;
[0025] See also Figure 3 , positioning block 4 is set at the center of the plug 3, and the positioning block 4 corresponds to the positioning groove 2. By cutting the tube body 1 or the angle steel body longer, and then embedding the plugs 3 at both ends into the two straight edges of the tube body 1 or the angle steel, welding is easy to fix, the position is controlled, the grinding workload is reduced, and the straightness of the two ends and the body is easy to control. This method not only improves the process, but also makes welding and grinding operations more convenient to control, saves working time, and improves efficiency.
[0026] See also Figure 2 A limiting groove 5 is vertically provided at the front center of the plug 3, and side rods 6 are transversely provided on both sides of the tube body 1. The plug 3 can be connected between the corresponding structures of the limiting groove 5 and the side rod 6.
[0027] See also Figure 4A fixed plate 7 is fixedly installed on the outer side of the center of the surface of the side rod 6, and an extrusion spring 8 is sleeved on the center of the surface of the side rod 6 and fits with the fixed plate 7. The extrusion spring 8 can drive the connecting structure to move along the surface of the side rod 6. A movable limit head 9 is sleeved laterally on the inner side of the center of the surface of the side rod 6 and fits with the extrusion spring 8, and a fixed limit head 10 is fixedly installed on the inner end surface of the side rod 6. The movable limit head 9 moves along the surface of the side rod 6 and under the action of the extrusion spring 8, approaching the fixed limit head 10, so that the movable limit head 9 and the fixed limit head 10 are clamped at the two ends of the plug 3, so as to facilitate the adjustment and movement operation of the plug 3. The limit groove 5 corresponds to the movable limit head 9 and the fixed limit head 10, and the limit groove 5, the movable limit head 9 and the fixed limit head 10 are all cross-shaped designs. The movable limiting head 9 and the fixed limiting head 10 are rotated through the limiting groove 5 of the plug 3 , so that the movable limiting head 9 and the fixed limiting head 10 are misaligned with the limiting groove 5 .
[0028] For example: the customer's drawing requires a 3300mm long pipe, and the plugs at both ends are designed to be 20mm each. The cut body should be 3260mm, so the welded plugs are all outside, which makes welding and grinding more troublesome. This solution cuts the length of the main pipe to 3300mm, reduces the size of the 20mm thick plug, and embeds the plug inside for welding.
[0029] This solution: by cutting the tube body 1 or the angle steel body longer, and then embedding the plugs 3 at the two end faces into the two straight edges of the tube body 1 or the angle steel, welding is easy to fix, the position is controlled, the grinding workload is reduced, and the straightness of the two ends and the body is easy to control. The side rod 6 drives the fixed limit head 10 to enter and rotate through the limit groove 5 of the plug 3, so that the movable limit head 9 and the fixed limit head 10 are misaligned with the limit groove 5. The movable limit head 9 moves along the surface of the side rod 6 and under the action of the extrusion spring 8, close to the fixed limit head 10, so that the movable limit head 9 and the fixed limit head 10 are clamped at the two ends of the plug 3, and the plug 3 is adjusted and moved.
