[0003] The Chinese invention patent with the patent number CN113134690B discloses a crossbeam structure of a floor-standing gantry laser cutting machine, including: a crossbeam body, a first base and a second base, the two ends of the crossbeam body spanning the two sides of the width direction of the bed of the laser cutting machine, the crossbeam body including a front composite main beam, a rear main beam, and a connecting piece connected between the front composite main beam and the rear main beam, the front composite main beam including at least two front main beams; the first base is arranged on one side of the bed, the first base is connected to one end of the crossbeam body; the second base is arranged on the other side of the bed, the first base is connected to the other end of the crossbeam body. The crossbeam structure of the invention adopts a composite beam structure design, which has better overall rigidity and higher bending strength, and can be applied to large-format cutting. At the same time, the welding and processing technology adopted by the present invention are relatively simple, and the overall manufacturing cost of the crossbeam is low.

[0004] Although the above scheme adopts a composite beam structure and is suitable for large-format cutting, it is relatively conservative in the specific main beam design and has not fully optimized the structure to improve the load-bearing and bending resistance. Therefore, the beam may deform when subjected to a large external force, causing the movement trajectory of the laser cutting head to deviate from expectations, thereby reducing the cutting accuracy. In addition, long-term operation under an overload or deformation state will accelerate the wear and aging of the beam structure and shorten the service life of the entire equipment.

[0025] See also Figure 1 , which is a three-dimensional structural diagram of a floor-standing gantry laser cutting machine crossbeam structure of the present invention; the floor-standing gantry laser cutting machine crossbeam structure of the present application increases the height of the first front main beam, making it the main load-bearing component, significantly enhancing the overall load-bearing capacity of the crossbeam, and effectively solving the technical problems of insufficient load-bearing and bending resistance, reduced cutting accuracy, shortened equipment performance and service life in the prior art, and achieving the technical effects of improved load-bearing and bending resistance, improved cutting accuracy, improved equipment performance and extended service life.

[0026] Embodiment 1: Figure 1 and Figure 2 As shown, the present application discloses a crossbeam structure of a floor-standing gantry laser cutting machine, including a crossbeam body, a base 200, a side end slide rail 400, and an upper end slide rail 500. The crossbeam body includes a first front main beam 100, a second front main beam 110, a rear main beam 120, and a connecting member 130; The base 200 is provided with two groups, which are respectively fixed at the left end and the right end of the beam body, and are used to connect the beam body and the lathe; The first front main beam 100 is a square tube structure and its height is higher than the second front main beam 110, serving as the main load-bearing component; the increase in the height of the first front main beam 100 significantly improves its load-bearing capacity and bending strength; The second front main beam 110 is fixed to the rear side of the first front main beam 100 by welding; The rear main beam 120 is fixed to the rear side of the second front main beam 110 through a plurality of connecting members 130 to form a rear end support of the cross beam body; The connecting members 130 are provided in plurality, including end connecting members and middle connecting members, and are used to connect the first front main beam 100 , the second front main beam 110 and the rear main beam 120 and enhance the overall rigidity of the cross beam body.

[0027] The side end slide rail 400 and the upper end slide rail 500 are respectively arranged on the side wall surface and the upper end surface of the front composite main beam, and are used to install the laser cutting head drive frame to achieve precise movement of the cutting head.

[0028] The base 200 includes a bottom plate 210, a vertical plate 1 220, a vertical plate 230 and a vertical plate 3 240; The bottom plate 210 is a rectangular steel plate, serving as the basic support surface of the base 200; The vertical plate 1 220 and the vertical plate 230 are respectively fixed on both sides of the bottom plate 210 to support one end of the crossbeam body; The third vertical plate 240 is fixed above the bottom plate 210 and is located between the first vertical plate 220 and the second vertical plate 230 .

[0029] Preferably, reinforcing rib plates 250 are fixed between the vertical plate 1 220 , the vertical plate 230 and the vertical plate 3 240 . The longitudinal cross-section of the reinforcing rib plates 250 is a triangular structure, which is used to enhance the structural strength of the base 200 .

[0030] During the actual laser cutting process of the embodiment of the present application, the crossbeam body bears the load generated by the movement of the laser cutting head and the cutting operation. As the height of the first front main beam 100 increases, the first front main beam 100 becomes the main load-bearing component, thereby sharing more of the load and correspondingly reducing the pressure on other components, so that the laser cutting head can move stably along the side end slide rail 400 and the upper end slide rail 500, thereby performing precise cutting operations.

[0031] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages: The invention solves the technical problems of insufficient load-bearing and anti-bending capacity, reduced cutting accuracy, shortened equipment performance and service life in the prior art, and achieves the technical effects of improved load-bearing and anti-bending capacity, improved cutting accuracy, improved equipment performance and extended service life.

[0032] Embodiment 2: In order to further enhance the bearing capacity and bending strength of the first front main beam 100 to meet the cutting requirements under different working conditions, the present application proposes the following technical solutions for the above technical problems, specifically: like Figure 1-Figure 3 As shown, the upper and lower ends of the first front main beam 100 are fixed with a bearing assembly 300 for enhancing the bearing capacity of the first front main beam 100, and the bearing assembly 300 includes a support block 310, a steel cable 320, and a roller 330; The support blocks 310 are provided in two groups and one end away from the first front main beam 100 is an arc-shaped structure, and are evenly distributed on the upper and lower end surfaces of the first front main beam 100, respectively, for supporting and distributing the load; The steel cables 320 are provided in two groups and arranged up and down, each group of steel cables 320 includes two steel cables 320 arranged front and back, and the two steel cables 320 are respectively arranged front and back at the two ends of the first front main beam 100 and respectively located at the upper and lower sides of the support block 310, for providing tension adjustment; The rollers 330 are provided in two groups and arranged up and down, and each group of rollers 330 includes two rollers 330 arranged on the left and right. The two rollers 330 are respectively fixed between the vertical plate 1 220 and the vertical plate 3 240 at the left and right ends, and are used to reel in the steel cable 320.

[0033] The bearing assembly 300 located at the top further includes a slave gear 340; The slave gear 340 is provided with two, which are respectively fixed on the front end of the roller 330 located above and rotatably connected to the corresponding vertical plate 220, and fixedly connected to the steel cable 320 for transmitting power. The bearing assembly 300 located at the bottom includes a main gear 350 and a motor 360; The main gear 350 is provided with two, which are respectively fixed to the front end of the roller 330 located below and meshed with the slave gear 340 to drive the slave gear 340 to rotate; The motor 360 is provided with two motors, which are respectively fixed on the vertical plate 220 on the left and right sides and the output ends thereof are respectively connected to the corresponding main gears 350, so as to drive the main gear 350 and the slave gear 340 to rotate and drive the roller 330 to rotate, thereby tightening and loosening the steel cable 320 to adjust the tension of the steel cable 320.

[0034] Preferably, the height of each group of support blocks 310 gradually decreases from the middle to both ends, so that the first front main beam 100 as a whole presents an arc-shaped structure that is high in the middle and low on both sides, which can more effectively support and disperse the weight and force of the first front main beam 100, and improve the stability and bearing capacity of the overall structure. Therefore, when the first front main beam 100 is subjected to bending moment, the first front main beam 100 with an arc-shaped structure can better resist bending deformation and maintain the stability and accuracy of the structure.

[0035] The present application can adjust the bearing capacity of the first front main beam 100 through the bearing assembly 300. When the bearing capacity needs to be adjusted to adapt to different working conditions, the motor 360 is started, and the motor 360 drives the main gear 350 to rotate forward and reverse, thereby driving the slave gear 340 to rotate accordingly, driving the rollers 330 at both ends to rotate, and then controlling the steel cable 320 to tighten or loosen, thereby adjusting the bearing capacity of the first front main beam 100. By dynamically adjusting the tension of the steel cable 320, the bearing capacity of the first front main beam 100 can be accurately controlled to ensure the stability and safety of the beam structure under different working conditions.

[0036] Embodiment 3: In order to further optimize the structure of the first front main beam 100 and the second front main beam 110, improve the bending resistance and rigidity of the entire beam, avoid single-plane force, and enhance the stability and durability of the beam structure, the present application proposes the following technical solutions for the above technical problems, specifically: like Figure 4 As shown, the second front main beam 110 and the first front main beam 100 are fixed alternately up and down to avoid the rigidity of the cross beam body being affected by force in a single plane.

[0037] Preferably, the second front main beam 110 is an I-shaped structure and is made of high-strength alloy steel.

[0038] The present application can increase the layering and stability of the crossbeam structure by fixing the first front main beam 100 and the second front main beam 110 in an alternating manner up and down, thereby preventing structural failure caused by single-plane force; at the same time, the I-shaped structure is an efficient cross-sectional shape that can provide higher bending rigidity and load-bearing capacity while maintaining a lighter weight, and can effectively resist deformation and vibration, especially under large-span and high-load conditions.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
