Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a crossbeam mechanism for laser cutting machine as shown in the figure, including connecting seat assembly 1 and crossbeam main part 2, connecting seat assembly 1 includes bottom plate 101, supporting seat 102 and driving motor 103, connecting seat assembly 1 is equipped with two and horizontal direction symmetry setting altogether, crossbeam main part 2 is cuboid hollow structure and cross section for "returning" style of calligraphy, the horizontal welding of upper surface of crossbeam main part 2 has first guide rail pair 3, the equal sliding connection in both ends of first guide rail pair 3 has guide rail slider 5, the welding has second guide rail 4 on the axis of crossbeam main part 2 preceding curb plate, the upper surface at two supporting seats 102 is fixed respectively at the both ends of crossbeam main part 2.

In addition, the material of crossbeam main part 2 is aviation aluminium, and through die-casting integrated into one piece, with the laser cutting machine crossbeam that aluminium alloy extruded, has solved the material mechanical properties that the crossbeam exists in production and application in the past relatively poor, and casting defect is many, and welding deformation is great, and the manufacturing cycle is long, only is used for a series of problems such as single, small batch production. The supporting seat 102 is provided with two, two the supporting seat 102 is rectangle and the size is the same, two the inside of supporting seat 102 all is equipped with strengthening rib 1021, and the top all is fixed with resistance to compression board 1022, is favorable to guaranteeing 2 level settings of crossbeam main part, can provide firm reliable support simultaneously.
