Description

Technical Field

[0001] This application relates to the technical field of positioning mechanisms, and more specifically, to a positioning mechanism for steel structure welding. Background Art

[0002] L-shaped right-angle steel joints are generally used to construct connection points in frame structures and are widely used in construction and bridge construction projects. They can provide high stiffness and stability and effectively transfer loads to adjacent components. In order to achieve a stable effect, when manufacturing L-shaped right-angle steel joints, it is necessary to weld the inclined welds at the right angles, and at the same time, welding reinforcement plates can be added at the end positions of each right-angle side to improve stiffness and stability. The straightness of the weld is one of the important factors determining the stiffness and stability of L-shaped right-angle steel joints. A welding positioning mechanism proposed in the existing publication number CN218695501U. This device uses the left rubber pad and the right rubber pad inside the left limit seat and the right limit seat. When placing iron workpiece, it effectively avoids sliding. The left limit seat can effectively change the position of the left positioning clamp above the left limit seat due to the expansion and contraction of the left positioning cylinders at both ends, so as to effectively adjust the clamping and positioning. The right limit seat can effectively change the position of the right positioning clamp above the right limit seat due to the right positioning cylinder inside, so as to effectively adjust the clamping and positioning. The automatic clamping and fixing effectively improve the overall clamping efficiency. In view of the above related technologies, the utility model person believes that there are still the following defects: The positioning mechanism in the comparative literature only positions the welding workpiece, but during welding, it cannot guide and position the movement of the welding gun. When welding an L-shaped steel joint, due to the inclined weld and the straight weld of the end reinforcement plate, if the welder's hand shakes, the weld will not be straight enough, and weld misalignment is likely to occur, resulting in insufficient flatness. In view of this, we propose a positioning mechanism for steel structure welding. Summary of the Utility Model

[0003] 1. Technical Problems to be Solved

[0004] The purpose of this application is to provide a positioning mechanism for steel structure welding, which solves the technical problem in the above-mentioned background art that the positioning mechanism in the comparative literature only positions the welding workpiece, but during welding, it cannot guide and position the movement of the welding gun. For example, when welding an L-shaped steel node, due to the presence of an inclined weld and a straight weld of the end reinforcing plate, if the welder's hand shakes, the weld will not be straight enough, and weld misalignment is likely to occur, resulting in insufficient flatness. The technical effect is achieved that a steel node with a right-angled structure shape is formed by splicing two I-shaped steel channels. The I-shaped steel channels of the steel node are stably positioned through the corner positioner, and the walking direction of the welding rod is guided and positioned through the corner positioner and the end positioner, so that the inclined weld at the right-angled part and the straight weld of the end reinforcing plate can be welded more smoothly and straightly, effectively avoiding the occurrence of misalignment or non-uniform flatness of the I-shaped steel channels of the steel node. The overall structure is simple, convenient to carry and install, and has strong practicability.

That is, the I-shaped steel channels of the steel joint 1 are respectively inserted and installed in a trapezoidal clamping block 21, and are threadedly pressed through two vertically arranged positioning bolts 26 threadedly installed on the connecting frame 24 to realize the positioning of the I-shaped steel channels of the steel joint 1. Then, the welding rod is guided through the welding rod inclined guide groove 23. An L-shaped plate 31 is slidably installed on each trapezoidal clamping block 21. Then, when welding the end reinforcing plate, the welding rod can be guided through the welding rod straight guide groove 311.

[0025] Refer to Figure 2 and Figure 3 , an inclined weld 11 is arranged at the connection of the two I-shaped steel channels of the steel joint 1.
