Cooling device for laser cutting machine

A cooling device for a laser cutting machine is provided with a cooling platform, a bottom support is arranged on the cooling platform, movable rolling wheels are arranged on the lower portion of the bottom support, the cooling platform is welded to the bottom support, a positioning platform is arranged on the cooling platform, a workpiece is placed on the positioning platform, and the positioning platform is welded to the bottom support. A transverse rod is arranged at the top of the cooling platform, a workpiece can be cut through laser cutting, after the workpiece is cut, the workpiece is moved to the cooling platform, a cooling fan is arranged on the cooling platform, air cooling is conducted on the workpiece through the cooling fan, and therefore subsequent machining of the workpiece is more convenient; and meanwhile, the physical performance of the workpiece can be guaranteed to a certain extent, and the positioning platform can be further cooled by adopting a positioning cross rod structure. 一种激光切割机用降温
