Technical Field

[0001] The utility model relates to the technical field of laser processing, in particular to a heavy truck beam automatic laser cutting device. Background Art

[0002] The laser cutting machine uses the energy released when the laser beam is irradiated onto the surface of the workpiece to melt and evaporate the workpiece, thereby achieving engraving and cutting. Special engineering vehicles are mostly modified on the basis of heavy trucks. In order to meet the characteristics of engineering vehicles, some unique facilities need to be installed on the beam, which also requires cutting and modification of the truck beam. The beams of heavy trucks are mostly channel steel. During the modification, artificial flame is currently used for cutting. The existing problem is that since the incision is serrated, not only a lot of manual grinding time is required in the later stage, but the serration points are also stress points, and the beam has the risk of cracking or even breaking. Therefore, laser cutting has a small heat-affected zone, less slag, and a smooth cross-section, which can be a good substitute for flame cutting of beams.

[0003] In the process of processing the beam of a heavy truck, a heavy truck beam laser automatic cutting equipment is needed. The laser automatic cutting equipment in the prior art performs laser cutting on the heavy truck beam by moving the laser automatic cutting equipment on the X and Y axes. However, the angle of the existing laser automatic cutting equipment is not convenient to adjust, and it is difficult to meet different usage requirements. The practicality is poor, which seriously affects the cutting efficiency of the laser automatic cutting equipment and cannot meet the usage requirements. Therefore, a heavy truck beam laser automatic cutting equipment is proposed to solve the above problems. Utility Model Content
