Hollow lathe body base of large-breadth cutting and welding equipment

Abstract

The invention discloses a hollow lathe body base of large-breadth cutting and welding equipment. The hollow lathe body base of the large-breadth cutting and welding equipment comprises an annular main body and an installation cavity formed in the inner side of the annular main body, and further comprises at least one split cross beam arranged in the installation cavity, each split cross beam comprises a vertical plate arranged in the installation cavity and two side supporting plates connected to the two sides of the bottom end of the vertical plate in a spaced mode, the vertical plates are connected to the annular main body through an end part limiting structure, the upper ends of the side supporting plates are connected to the vertical plates through side surface limiting structures, the side supporting plates are arranged in the length direction of the vertical plates, and the two ends of the side supporting plates are connected through end part guiding structures. According to the hollow lathe body base of the large-breadth cutting and welding equipment, the heating surface of the split cross beam is reduced, heat accumulation is avoided, meanwhile, the hollow lathe body base can adapt to the structural change of deformation of the vertical plates when the plate surfaces of the vertical plates are heated, and meanwhile, good connection reliability between the vertical plates and connecting plates can still be kept.

Description

technical field [0001] The invention belongs to the technical field of laser cutting and welding machines, in particular to a hollow body-passing base of large-format cutting and welding equipment. Background technique [0002] Laser cutting is the use of high-power density laser light speed to focus on the set coordinate point to form a large energy cutting or welding material. Laser cutting has the advantages of fast cutting speed, high production efficiency, and small heat-affected zone. It has become the main cutting method for metal sheets. one. [0003] At present, when the bed of laser equipment is subjected to laser cutting and welding operations, its bed is prone to structural deformation under long-term heating, which reduces the accuracy of laser cutting coordinates and causes the laser equipment to fail. For example, the Chinese patent literature discloses a high-power laser cutting bed [Application No.: 202020827320.5], including the bed, a number of square gro...
