Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a steel structure welding robot which is easy to position. Background Art

[0002] Welding robots are industrial robots that perform welding. According to the definition of the International Organization for Standardization, industrial robots are standard welding robots. Industrial robots are multi-purpose, reprogrammable, automatically controlled manipulators used in the field of industrial automation. When processing weldments, weldment positioning devices are often required to fix the weldments so that subsequent welding robots can perform welding.

[0003] The existing weldment positioning device cannot fully adjust the steel structure in actual use, so that the welding robot can only weld the surface of the steel structure. At the same time, the weldment needs to change the fixed angle and weld multiple times during welding, which reduces the welding efficiency. In addition, the welding stability coefficient is low, making it difficult to stably clamp and position the steel structure, and cannot meet the needs of high-quality welding operations on steel structures.

The problem solved by the present invention is that the steel structure cannot be adjusted in all directions, so that the welding robot can only weld the surface of the steel structure. At the same time, the weldment needs to be replaced with a fixed angle and welded multiple times during welding, which reduces the welding efficiency. In addition, the welding stability coefficient is low, and it is difficult to stably clamp and position the steel structure, which cannot meet the needs of high-quality welding operations on the steel structure. The present invention combines the above-mentioned components with each other, integrates the telescopic positioning mechanism 2, the pressing positioning mechanism 5, the position adjustment mechanism 3 and the rotating welding structure 4, and realizes flexible welding operations after precise positioning of the steel structure in three-dimensional space. The rotating welding structure 4 slidably connected in front of the adjustment mechanism 3 realizes the precise adjustment of the welding position on the X, Y, and Z axes, which provides great convenience for the welding of complex steel structures. The welding angle can be flexibly adjusted to adapt to welds of different shapes and positions, which greatly improves the welding efficiency and quality, reduces manual intervention, reduces the difficulty of operation, and also improves the safety of the operation. Multiple sets of telescopic positioning mechanisms 2 ensure the stable horizontal welding of the steel structure and enhance the accuracy of positioning. The pressing positioning mechanism 5 arranged above the hydraulic rod 231 in the middle realizes the stability of the steel structure during the longitudinal welding process, which meets the current steel structure manufacturing industry's demand for high-quality and high-efficiency welding operations.
