Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting equipment, and in particular relates to a crossbeam of a gantry laser cutting machine. Background Art

[0002] As a common processing method in modern manufacturing, laser cutting machines break the traditional processing methods and are widely used in various industries with a new cutting process. The cutting speed and accuracy have always been important criteria for measuring the quality of laser cutting machines. At present, most large-scale laser cutting machines are moving beam gantry structures, in which the crossbeam, as a key component, has a direct impact on the cutting speed and accuracy. The common laser cutting machine crossbeams on the market are mainly divided into two forms: welding and casting.

[0003] The welded beams made of steel plates or profiles and steel plates are heavy and have large inertia, resulting in poor dynamic response, affecting the stability and accuracy of the equipment. They may also require a higher-power drive motor, increasing costs. Cast aluminum alloy beams are light and suitable for high-speed cutting, but they have poor rigidity and poor surface quality. They are prone to deformation after long-term use, reducing the accuracy and stability of the equipment. Utility Model Content

[0004] In order to solve the above problems of the prior art, the utility model provides a gantry laser cutting machine beam, which is extruded from aviation aluminum, reduces the weight of the beam, reduces the defects of the existing cast aluminum beam, and also reduces the deformation of the beam, thereby ensuring its strength and rigidity, thereby improving the speed and accuracy of the gantry laser cutting machine.

[0005] To achieve the above purpose, the utility model provides the following solutions:

[0006] In a first aspect, the utility model provides a gantry laser cutting machine beam, comprising:

[0007] A beam body and support seats symmetrically arranged at left and right ends of the beam body;

[0008] The beam body includes an outer frame and an inner frame arranged at intervals inside the outer frame, a plurality of connecting plates are arranged between the inner side of the outer frame and the outer side of the inner frame, oblique reinforcing ribs are arranged between the inner frame, the outer frame and the connecting plates, and two adjacent oblique reinforcing ribs are arranged in a V shape;

[0009] The upper end of the beam body and the front side thereof are respectively provided with a first guide rail mounting groove and a rack mounting boss, and the front side of the beam body is provided with a second guide rail mounting groove.

[0010] In a feasible implementation, the beam body is formed by integral extrusion.

[0011] In a feasible implementation, the beam body is an aluminum beam body.

[0012] In a feasible implementation, the beam body is made of aviation aluminum.

[0013] In a feasible implementation, the cross-sections of the outer frame and the inner frame are both rectangular, the connecting plates are arranged between the four inner corners of the outer frame and the four outer corners of the inner frame, and the oblique reinforcing ribs are arranged around the outer side of the inner frame.

[0014] In a feasible implementation, the sides of the outer layer frame and the inner layer frame are provided with through holes.

[0015] In a feasible implementation, a plurality of vertical reinforcing ribs are arranged around the outer side of the inner frame and between the outer frame and the connecting plate along the length direction of the beam body.

[0016] In a feasible implementation, the vertical reinforcement rib is arranged between two adjacent oblique reinforcement ribs.

[0017] In a feasible implementation, the support seat and the beam body are formed integrally.

[0018] In a feasible implementation, a mounting hole is provided on the support base.

[0019] In a feasible implementation, a lateral reinforcement plate is provided at the connection between the support seat and the beam body.

[0020] In a feasible implementation, a pair of lateral reinforcement plates are respectively provided at the connection between the support base and the beam body at the left and right ends.

[0021] In a feasible implementation, the beam body at the connection between the support seat and the lateral reinforcement plate is provided with at least one through hole.

[0022] In a feasible implementation, the four inner corners of the inner layer skeleton are all rounded.

[0023] In a second aspect, the utility model provides a gantry laser cutting machine including the above-mentioned crossbeam.

[0024] Compared with the prior art, the beneficial effects of the utility model are:

[0025] (1) The utility model provides a gantry laser cutting machine crossbeam, in which the beam body is extruded from aviation aluminum. The aviation aluminum material has a low density, and the one-piece extrusion molding process can further reduce the use of materials, thereby achieving lightweight crossbeams. The lightweight crossbeam has a small inertia and can improve the dynamic response speed. At the same time, the one-piece extrusion molding process can reduce defects that may occur during the casting process, such as bubbles, etc., thereby improving the processing accuracy of the crossbeam and the overall accuracy of the cutting machine. The one-piece molding process can also maintain the integrity of the material, avoid the problems of heat-affected zones and material performance degradation that may occur during welding, thereby improving the overall rigidity of the crossbeam. In addition, the thermal expansion coefficient of aviation aluminum alloys is low, which is conducive to maintaining the dimensional stability of the beam in an environment with temperature changes and reducing the impact of thermal deformation on cutting accuracy.

[0026] (2) The gantry laser cutting machine crossbeam provided by the utility model comprises an outer frame and an inner frame. When the span of the crossbeam is large, the double-layer structure of the inner frame and the outer frame can effectively resist bending and twisting, thereby ensuring the stability of the crossbeam during movement. Oblique reinforcement ribs are arranged between the inner frame, the outer frame and the connecting plate, which provide bending and torsional resistance in two directions and can distribute stress more evenly. Vertical reinforcement ribs are arranged between adjacent oblique reinforcement ribs along the length direction of the beam body, thereby achieving uniform stress distribution. At the same time, through holes are arranged through the sides of the outer frame and the inner frame of the beam body, thereby reducing the weight of the beam body without sacrificing rigidity, realizing lightweight design, and further improving the dynamic response speed.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] Example 1

[0037] See also Figures 1 to 7 The utility model provides a gantry laser cutting machine crossbeam, comprising: an aviation aluminum beam body 1 formed by integral extrusion and support seats 2 symmetrically arranged at the left and right ends of the beam body 1. The beam body 1 comprises an outer frame 11 and an inner frame 12 arranged at intervals inside the outer frame 11. The cross sections of the outer frame 11 and the inner frame 12 are both rectangular. When the span of the crossbeam is large, the double-layer structure of the inner frame 12 and the outer frame 11 can effectively resist bending and twisting, and ensure the stability of the crossbeam during movement. A plurality of connecting plates 13 are arranged between the inner four corners of the outer frame 11 and the outer four corners of the inner frame 12, and oblique reinforcing ribs 14 are arranged between the outer frame 11, the inner frame 12 and the connecting plates 13. The oblique reinforcing ribs 14 are arranged around the outer side of the inner frame 12, and two adjacent oblique reinforcing ribs 14 are arranged in a V-shape, providing bending and torsion resistance in two directions, and being able to distribute stress more evenly. The sides of the outer frame 11 and the inner frame 12 are provided with through holes 17, which achieve lightweight while ensuring the necessary rigidity and strength. A plurality of vertical reinforcing ribs 18 are arranged around the outer side of the inner frame 12 and between the outer frame 11 and the connecting plate 13 along the length direction of the beam. The vertical reinforcing ribs 18 are arranged between two adjacent oblique reinforcing ribs 14, so as to achieve uniform stress distribution. The inner four corners of the inner frame 12 are processed into rounded corners. The use of rounded corner transition can reduce stress concentration and extend the service life of the beam.

[0038] Aviation aluminum materials have low density, and the one-piece extrusion molding process can further reduce material usage, thereby achieving lightweight crossbeams. Lightweight crossbeams have small inertia and can improve dynamic response speed.

[0039] The one-piece extrusion molding process can reduce defects that may occur during the casting process, such as bubbles, thereby improving the processing accuracy of the beam and the overall accuracy of the cutting machine. At the same time, the one-piece molding process can maintain the integrity of the material, avoid the heat-affected zone and material performance degradation that may occur during welding, thereby improving the overall rigidity of the beam. In addition, the thermal expansion coefficient of aviation aluminum alloy is low, which is conducive to maintaining the dimensional stability of the beam in an environment with temperature changes and reducing the impact of thermal deformation on cutting accuracy.

[0040] The upper end and the front side of the beam body 1 are respectively provided with a first guide rail mounting groove 15 and a rack mounting boss 16, which are convenient for the installation of the head guide rail and the head motor rack, and are used for connection with the laser cutting machine. A second guide rail mounting groove 15 is provided on the front side of the beam body 1. The support seat 2 is integrally formed with the beam body 1, and a plurality of mounting holes (such as holes for fixing the drive motor or for installing the slider on the guide rail) are provided on the support seat 2. Lateral reinforcing plates 21 are symmetrically provided at the connection between the support seat 2 and the beam body 1. A pair of lateral reinforcing plates 21 are respectively provided at the connection between the support seat 2 and the beam body 1 at the left and right ends, so as to increase the stability of the connection between the support seat 2 and the beam body 1. At least one through hole 17 is provided on the beam body 1 at the connection between the support seat 2 and the lateral reinforcing plate 21, so that the operator can conveniently pass through the through hole 17 to maintain the mounting mechanism (such as the drive motor) on the support seat 2.
