The right-angle positioning tool is a commonly used auxiliary welding component. The existing right-angle positioning components for welding are generally cut and formed right-angle triangles, with general positioning effects and inconvenient operation. After searching, the right-angle positioning component of the large square tube frame precision welding tool with publication number CN213196309U is used. The first and second positioning members at right angles are placed at the right angles of the two square tubes of the frame, and then the first positioning pin is inserted into the first positioning hole and the through hole on one square tube, and the second positioning pin is inserted into the second positioning hole and the through hole on the other square tube. The first positioning hole and the second positioning hole accurately correspond to the through hole on the square tube, and then accurate positioning is achieved by the first positioning pin and the second positioning pin. The two square tubes of the frame are formed into a vertical state of 90 degrees, and then the two square tubes are welded and fixed to realize the frame welding tool, which improves the welding accuracy of the square tube frame. However, this solution requires frequent fixing by the positioning pin and the positioning hole, which is easy to wear after long-term use, and it is also inconvenient to install and disassemble.
