Description

technical field [0001] The invention relates to a working platform, in particular to a working platform used in cooperation with a welding robot for research on high-strength steel welding processes. Background technique [0002] In the development of fields such as construction, railways, aviation, ships, pressure vessels and construction machinery, high-strength steel is gradually used in the production and manufacture of products due to its high strength, good ductility and other properties. [0003] Because the welding process of high-strength steel is not mature enough, which directly affects its application in engineering, it is necessary to conduct in-depth research on its welding process, and use welding robots for experimental research. The traditional high-strength steel welding process research often changes the welding current, arc voltage, welding speed, etc. to find a set of parameters suitable for welding the steel. Due to the lack of consideration of the heat...

AI Technical Summary

Problems solved by technology

[0005] 1. Unable to accurately locate the welding position

[0006] The traditional welding work platform is mainly aimed at manual welding technology. Although the structure is simple and the operation is convenient, with the application of robot welding technology, it is necessary to master the accurate welding position before welding in order to teach and program the robot. The traditional work platform can no longer meet the requirements. Welding Positioning Requirements

[0007] 2. The welding, heating and cooling of the workpiece cannot be carried out at the same position

[0008] In the traditional welding process, the welding, heating, and cooling of the workpiece are carried out at different positions. Although the expected purpose can be achieved, the workpiece needs to be disassembled and transported, resulting in reduced efficiency and increased labor intensity. Heat loss will directly affect the accuracy of the welding test

[0009] 3. The heating and cooling of the workpiece is uncontrollable

[0010] The workpiece is often heated by flame heating. Although this heating method is low in cost, it is difficult to operate, and it is not easy to control the heating temperature and cannot ensure that the workpiece is heated evenly, which is easy to cause overheating

The cooling of welding workpieces often adopts air cooling, the cooling rate is low, and it is not easy to change

High-strength steel has strict requirements on the welding environment, and traditional heating and cooling methods cannot meet the advanced welding process requirements

[0011] 4. Insufficient welding protection

[0012] Using the traditional gas shielded welding technology to weld the workpiece, the welding torch will spray shielding gas to protect the surface of the weld seam, but the bottom of the weld seam is exposed in the air, which is difficult to be protected and reduces the welding quality

[0013] Therefore, it is difficult for traditional welding platforms to cooperate with welding robots to realize advanced welding process research
