Description

Technical Field

[0001] This utility model belongs to the field of cutting machinery, specifically a laser cutting machine beam and a laser cutting machine. Background Technology

[0002] Laser cutting machines are widely used for precision cutting of various materials, playing a particularly important role in metal processing, automobile manufacturing, and electronic component production. The performance of a laser cutting machine is directly limited by the design of one of its key components—the crossbeam. The crossbeam primarily bears the load of the laser cutting machine and supports important components such as the laser head; its structural stability, strength, and rigidity directly affect cutting accuracy and equipment operating efficiency.

[0003] Currently, most laser cutting machine beams are made of aluminum alloy or steel. While these materials offer light weight and a certain level of strength, they are prone to deformation under large spans and high loads, leading to a decrease in cutting accuracy. Especially during high-speed cutting, the beam structure's insufficient rigidity and limited load-bearing capacity can easily cause instability in laser cutting machine accuracy, affecting production efficiency and processing quality.

[0004] To address these issues, some new designs have begun to employ techniques such as reinforcing ribs, composite materials, and structural optimization to enhance the strength and stability of crossbeams. For example, reinforcing ribs are added to the front and rear beam structures to improve bending and torsional resistance. However, existing technologies still have certain design flaws, such as insufficiently optimized rib layout, inadequate weight reduction design, and insufficient dynamic performance of crossbeams under long spans and high loads. Utility Model Content

[0005] Maintaining high strength and rigidity of the crossbeam while reducing material usage, lightening the overall weight, and improving the stability and precision of the laser cutting machine has become a significant challenge in crossbeam design. To address these needs, this invention provides a laser cutting machine crossbeam and a laser cutting machine itself. By improving material configuration, structural layout, and the design of reinforcing ribs, the crossbeam's load-bearing capacity, rigidity, and dynamic performance are enhanced to meet the working requirements of large-span, high-load laser cutting machines, thereby improving the machine's efficiency and cutting precision.

[0006] This utility model is achieved through the following technical solution: A laser cutting machine crossbeam includes a crossbeam body, the crossbeam body including a front beam and a rear beam for the main load-bearing part, the rear beam being fixed to the side of the front beam to support the rear end; a reinforcing rib group, the reinforcing rib group having multiple ribs arranged along the inner length direction of the crossbeam body; the reinforcing rib group including a front beam vertical rib, the front beam vertical rib being disposed in the inner cavity of the front beam and connected to the upper and lower surfaces of the inner cavity of the front beam; and a front beam U-shaped rib; the front beam U-shaped rib being embedded in the groove of the front beam vertical rib and perpendicular to the upper and lower surfaces of the inner cavity of the front beam. Through the combination of the front and rear beams, the stability of the crossbeam during the operation of the laser cutting machine is ensured, effectively bearing the load and improving the rigidity of the overall structure, reducing deformation, and improving accuracy; the design of the reinforcing ribs greatly improves the load-bearing capacity and rigidity of the front beam, effectively dispersing the external forces generated during the operation of the laser cutting machine, ensuring the crossbeam remains stable under high loads, and guaranteeing high precision in laser cutting.

[0007] Further improvements to this invention include the fact that both the front beam and the rear beam are rectangular tube structures, with the front beam being higher than the rear beam. The rectangular tube structure design enhances the bending strength of the crossbeam, and the higher front beam provides stronger support for the laser cutting machine, ensuring that the crossbeam can work stably under large span and high load conditions.

[0008] A further improvement of this invention is that the main body of the crossbeam also includes sealing plates, which are disposed at both ends of the inner cavity of the front beam and have the same shape as the cross-sectional shape of the inner cavity of the front beam. The sealing plates improve the overall rigidity of the front beam, prevent the possibility of foreign objects entering the inner cavity, and enhance the sealing and durability of the crossbeam, thereby improving the stability and service life of the laser cutting machine.

[0009] A further improvement of this utility model is that the main body of the crossbeam also includes a mounting plate, which comprises a column side plate, a column middle plate, a column front and rear plate, and a motor mounting plate; the motor mounting plate is parallel to the upper surface of the front beam; the column side plate is perpendicular to the bottom of the front beam and located above the motor mounting plate; the column middle plate is perpendicular to the bottom of the front beam and located above the motor mounting plate; the column front and rear plates are parallel to the column middle plate, and are disposed at the bottom of the front beam and above the motor mounting plate. The design of the mounting plate provides stable support for the motor and other key components of the laser cutting machine, enhancing the overall stability and shock resistance of the crossbeam, and ensuring the accuracy of the equipment during high-speed, high-load operation.

[0010] A further improvement of this invention is that the mounting plate also includes a protective cover mounting plate, which is disposed at both ends of the motor mounting plate. The design of the protective cover mounting plate effectively protects the motor and key components from external contamination and damage, while stabilizing the motor's operating environment and extending the equipment's service life.

[0011] A further improvement of this utility model is that the main body of the crossbeam also includes reinforcing ribs, which are arranged at the bottom of the front and rear beams of the crossbeam and connected to the side plates of the column; the arrangement of the reinforcing ribs enhances the overall strength of the crossbeam, improves its resistance to bending and torsion, and ensures the stability and high-precision cutting of the laser cutting machine under high load.

[0012] A further improvement of this utility model is that the front beam, the front beam vertical rib, the front beam U-shaped rib, and the sealing plate are all provided with weight-reducing holes; the design of the weight-reducing holes effectively reduces the overall weight of the crossbeam, lightens the burden on the laser cutting machine, improves the movement efficiency of the equipment, and ensures that the crossbeam can withstand higher working loads while ensuring strength.

[0013] A further improvement of this utility model is that the main body of the crossbeam also includes an upper mounting plate, which is disposed on the upper surface of the front beam and fixed in the Y direction along the length of the main body of the crossbeam; the design of the upper mounting plate provides additional support, enhances the rigidity of the crossbeam, ensures the stability of the laser cutting machine during high-speed operation, and effectively prevents the crossbeam from deforming during the cutting process.

[0014] A further improvement of this utility model is that it also includes a first guide rail mounting plate and a second guide rail mounting plate; the first guide rail mounting plate is fixed to the outer side of the front beam along the Y direction of the length of the main body of the crossbeam and is provided with a step; the second guide rail mounting plate is welded and fixed along the Y direction of the length of the main body of the crossbeam and is provided with a step; the step design of the guide rail mounting plate ensures the stable installation of the guide rail, improves the overall stability and accuracy of the crossbeam, and ensures the accuracy and efficiency of the laser cutting machine in the high-speed cutting process.

[0015] A laser cutting machine includes a bed and a laser cutting machine beam; an X-axis drive mechanism is installed on the bed, the moving part of the X-axis drive mechanism is connected to the end of the beam body, and a head module is installed on the beam body; through the connection of the X-axis drive mechanism, the beam can achieve precise high-speed movement, and the stable installation of the head module ensures the stability and high precision of the cutting head, thereby improving the working efficiency and accuracy of the laser cutting machine.

[0016] As can be seen from the above technical solution, the beneficial effects of this utility model are as follows: the crossbeam structure of the laser cutting machine, through the combination of the front and rear beams and the design of the reinforcing rib group, significantly improves the load-bearing capacity, rigidity, and stability of the crossbeam. The design of the front beam vertical ribs and the front beam U-shaped ribs enhances the bending and deformation resistance of the front beam, enabling the crossbeam to maintain structural stability under the high load and high speed of the laser cutting machine, preventing deformation, thereby improving the accuracy and reliability of the laser cutting machine. The layout of the reinforcing rib group effectively distributes the external load, allowing the crossbeam to withstand greater working pressure, maintain high stability, and ensure higher cutting accuracy during the laser cutting process.

[0017] Meanwhile, this utility model significantly improves the performance and stability of the laser cutting machine's crossbeam through a series of optimized designs. Both the front and rear beams adopt rectangular tube structures, with the front beam being higher than the rear beam. This design enhances the crossbeam's resistance to bending and torsion, enabling it to withstand larger loads and ensuring the laser cutting machine's operational stability and cutting accuracy under high-load conditions. Sealing plates are located at both ends of the front beam's inner cavity, their shape matching the cross-sectional shape of the front beam's inner cavity. This effectively enhances the front beam's rigidity and prevents external debris from entering the inner cavity, improving the overall strength and service life of the crossbeam. The mounting plate includes column side plates, column middle plates, column front and rear plates, and a motor mounting plate. The rational layout of these components makes the crossbeam structure more stable, improving its seismic resistance and load-bearing capacity, ensuring the long-term efficient operation of the laser cutting machine. Protective cover mounting plates are located at both ends of the motor mounting plate, protecting the motor and other critical components from external environmental contamination, improving the equipment's durability and operational stability. Reinforcing ribs are installed at the bottom of the front and rear beams and connected to the side plates of the columns, further enhancing the strength and stability of the crossbeams and ensuring high precision and stability even under heavy loads. The weight-reducing hole design not only reduces the overall weight of the crossbeams but also maintains their strength and rigidity, optimizing the operating efficiency and power consumption of the laser cutting machine. An upper mounting plate is installed on the upper surface of the front beam and fixed along the length of the crossbeam body, enhancing its rigidity and stability and ensuring the laser cutting machine maintains stability during high-speed operation. The guide rail mounting plate design includes first and second guide rail mounting plates, fixed along the length of the crossbeam body and featuring steps, improving the stability of the guide rails and ensuring the cutting accuracy and motion stability of the laser cutting machine. The X-axis drive mechanism is connected to the end of the crossbeam body, ensuring precise movement of the crossbeam, while the head module is mounted on the crossbeam body, providing core support for the cutting task and improving the precision and efficiency of the laser cutting machine. Through these optimized designs, the overall structure of the crossbeam is more stable and precise, maintaining efficient and stable operation under high-speed, high-load conditions, ensuring high precision and stability of the laser cutting machine during long-term operation.

[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0025] refer to Figure 1-4 As shown, this utility model discloses a crossbeam for a laser cutting machine. Through the reasonable layout of the front beam 1, the rear beam 2, and the reinforcing rib group, the load-bearing capacity, rigidity, and stability of the crossbeam are significantly improved, thereby ensuring that the laser cutting machine maintains high precision and stability during high-speed operation.

[0026] Specifically, the main body of the crossbeam includes a front beam 1 and a rear beam 2. The front beam 1, as the main load-bearing component, adopts a rectangular tube structure and its height is greater than that of the rear beam 2. The rear beam 2 is fixed to the side of the front beam 1 by welding, forming the rear end support of the main body of the crossbeam, which enhances the stability and load-bearing capacity of the crossbeam.

[0027] To enhance structural strength, multiple reinforcing ribs are arranged along the length of the crossbeam's inner cavity, including front beam vertical ribs 6 and front beam U-shaped ribs 7. The front beam vertical ribs 6 are located within the front beam 1 cavity and connected to the upper and lower surfaces of the cavity, improving the rigidity of the front beam and preventing deformation under load. The front beam U-shaped ribs 7 are embedded in the grooves of the front beam vertical ribs 6 and welded perpendicularly to the upper and lower surfaces of the front beam 1 cavity. This structure increases the overall bending resistance of the front beam, further strengthening its rigidity and stability. In use, the four inner sides of the front beam U-shaped ribs 7 are fixedly connected to the grooves of the front beam vertical ribs 6, forming the crossbeam body. In the following embodiment, the length direction of the front beam is Y-direction. Through the reasonable arrangement of reinforcing ribs, the external forces and loads borne by the crossbeam are effectively distributed, preventing deformation due to excessive load and ensuring the accuracy and stability of the laser cutting machine during high-speed, high-load operation. Simultaneously, the structural design of the front beam 1, front beam vertical ribs 6, and front beam U-shaped ribs 7 components reduces unnecessary material usage, effectively reducing the overall weight of the crossbeam. The reduced weight not only optimizes the motion performance of the laser cutting machine, but also reduces the burden on the drive system, thereby improving operating efficiency.

[0028] Both the front beam 1 and the rear beam 2 adopt a rectangular tube structure, with the front beam 1 being taller than the rear beam 2. This design allows the front beam 1, as the main load-bearing component of the crossbeam, to withstand more loads and provide stronger support. The rectangular tube structure itself has excellent bending and torsional resistance, effectively resisting various forces generated during the high-speed operation of the laser cutting machine, ensuring the overall stability and structural strength of the crossbeam.

[0029] The higher height of the front beam 1 compared to the rear beam 2 further optimizes the structural balance of the crossbeam. The higher front beam 1 provides stronger support for the working parts of the laser cutting machine, while the lower rear beam 2 reduces the overall weight and optimizes the center of gravity distribution of the crossbeam while ensuring structural stability. The rear beam 2 is welded to the side of the front beam 1, serving as the rear-end support of the crossbeam body, enhancing the overall rigidity and load-bearing capacity of the crossbeam, and helping to improve the crossbeam's resistance to bending and deformation.

[0030] The main body of the crossbeam also includes sealing plates 8, which are located at both ends of the inner cavity of the front beam 1, and the shape of the sealing plates 8 is the same as the cross-sectional shape of the inner cavity of the front beam 1. This design, by welding the sealing plates 8 to both ends of the inner cavity of the front beam 1, not only effectively seals the inner cavity of the crossbeam, but also enhances the structural stability of the front beam 1 when subjected to external forces. The shape of the sealing plates 8 is consistent with the cross-section of the inner cavity of the front beam 1, allowing it to better fit with the front beam 1 and form a tighter connection structure. The installation of the sealing plates 8 not only prevents external debris from entering the inner cavity of the front beam 1, protecting the internal structure from contamination, but also increases the overall rigidity of the front beam 1 and improves its bending resistance, especially when the laser cutting machine is moving at high speed, ensuring that the crossbeam can withstand greater loads without deformation.

[0031] The main body of the crossbeam also includes a mounting plate, which comprises a column side plate 10, a column middle plate 11, column front and rear plates 12, and a motor mounting plate 13. The motor mounting plate 13 is parallel to the upper surface of the front beam 1, ensuring stable support for the motor and preventing a decrease in cutting machine accuracy due to vibration or unstable connections. The column side plate 10 is perpendicular to the bottom of the front beam 1 and located above the motor mounting plate 13, working together with the column middle plate 11 to enhance the crossbeam's resistance to bending and deformation. The column front and rear plates 12 are parallel to the column middle plate 11, positioned at the bottom of the front beam 1 and above the motor mounting plate 13, further strengthening the overall structural stability and preventing unnecessary vibration during high-speed laser cutting. This layout not only provides strong support and improves overall rigidity but also ensures the stability and accuracy of the laser cutting machine under high load and high speed operation, reducing equipment maintenance frequency and extending service life.

[0032] The mounting plate also includes a protective cover mounting plate 14, which is disposed at both ends of the motor mounting plate 13. The protective cover mounting plate 14 is designed primarily to secure the motor and other critical components, protecting them from external contamination and damage. By placing the protective cover mounting plate 14 at both ends of the motor mounting plate 13, comprehensive protection of the motor is ensured, effectively preventing dust and debris from entering the motor area and extending the motor's service life. Furthermore, the fixed connection between the protective cover mounting plate 14 and the motor mounting plate 13 enhances the overall structural stability of the crossbeam, providing additional support for the laser cutting machine, helping to reduce vibration during operation, and further improving the equipment's stability and precision. Through this design, the protective cover mounting plate 14 not only protects the motor components but also optimizes the operating environment of the laser cutting machine, improving the equipment's working efficiency and reliability.

[0033] The main body of the crossbeam also includes reinforcing ribs 9, which are located at the bottom of the front beam 1 and the rear beam 2 and connected to the column side plate 10. The design of these reinforcing ribs 9 aims to further enhance the overall strength and stability of the crossbeam, especially under heavy loads. By placing the reinforcing ribs 9 at the bottom of the front beam 1 and the rear beam 2 and connecting them to the column side plate 10, the external pressure on the crossbeam can be effectively distributed, improving its resistance to bending, torsion, and deformation. The connection between the reinforcing ribs 9 and the column side plate 10 forms a more stable support structure, enhancing the overall load-bearing capacity of the crossbeam. This design ensures that the laser cutting machine maintains accuracy during high-speed operation, prevents cutting errors caused by excessive deformation, and improves the stability and accuracy of the cutting effect. Through this optimized design, the strength and stability of the crossbeam are significantly improved, effectively extending the service life of the laser cutting machine and reducing equipment maintenance costs.

[0034] The front beam 1, front beam vertical ribs 6, front beam U-shaped ribs 7, and sealing plate 8 are all equipped with weight-reducing holes. The design of these holes aims to effectively reduce the overall weight of the crossbeam without compromising its strength and rigidity. Multiple circular weight-reducing holes are provided along the length of the front beam 1 and front beam vertical ribs 6, while square weight-reducing holes are provided on the front beam U-shaped ribs 7, and circular weight-reducing holes are also provided on the sealing plate 8. This layout not only helps reduce material usage and lower the weight of the crossbeam, thus reducing the overall burden on the laser cutting machine, but also effectively improves the equipment's operational efficiency. While reducing weight, these weight-reducing holes, through their rational hole placement design, optimize the rigidity and strength of the crossbeam, ensuring that the laser cutting machine maintains sufficient stability and precision even at high speeds. The overall structural design makes the crossbeam lighter, stronger, and more durable, enabling it to improve the working efficiency of the laser cutting machine, reduce energy consumption, and extend the equipment's service life while ensuring high load-bearing capacity.

[0035] The main body of the crossbeam also includes an upper mounting plate 5, which is disposed on the upper surface of the front beam 1 and fixed along the Y-direction of the crossbeam's length. The main function of the upper mounting plate 5 is to provide additional support and stability, ensuring that the front beam 1 maintains its structural integrity under high-speed movement and high load conditions. By fixing the upper mounting plate 5 to the upper surface of the front beam 1 and arranging it along the Y-direction of its length, various forces from the laser cutting machine during operation can be effectively distributed and evenly distributed, preventing excessive deformation of the front beam 1. In addition, the upper mounting plate 5 provides a platform for the installation of other components of the laser cutting machine, ensuring a stable connection between the various parts. During high-speed, high-load operation, the upper mounting plate 5 helps to enhance the overall rigidity and load-bearing capacity of the front beam 1, thereby ensuring the operating accuracy and stability of the laser cutting machine. At the same time, the reasonable fixing design also optimizes the overall structure of the equipment, reduces vibration, and further improves work efficiency and equipment reliability.

[0036] The upper mounting plate 5 is equipped with a bellows cover guide step, which extends along the Y-direction of the crossbeam body. The purpose of the bellows cover guide step is to provide guidance support for the stable movement of the bellows cover, ensuring that the bellows cover can smoothly extend and retract during high-speed operation of the laser cutting machine. As the head module moves, the bellows cover will extend and retract with the operation of the equipment. The guide step can guide the bellows cover to maintain the correct movement trajectory and avoid affecting the drive structure between the head and the crossbeam due to unstable movement.

[0037] By setting the bellows cover guide steps on the upper mounting plate 5 and extending them along the Y-direction of the crossbeam body, the design ensures the stability and adjustability of the bellows cover, while protecting the drive structure between the crossbeam and the machine head from external environmental interference, such as dust and debris. This design not only improves the protective performance of the equipment but also reduces maintenance frequency, extends the service life of the equipment, and ensures the high efficiency and stability of the laser cutting machine in long-term use.

[0038] It also includes a first guide rail mounting plate 3 and a second guide rail mounting plate 4. The first guide rail mounting plate 3 is fixed to the outer side of the front beam 1 along the Y-direction of the beam body and has a step. The second guide rail mounting plate 4 is welded and fixed along the Y-direction of the beam body and also has a step. The step design not only helps to stabilize the installation of the guide rail, but also ensures a tight connection between the guide rail and the beam, improving the stability and precision of the overall structure. The first guide rail mounting plate 3 provides a solid support platform for the guide rail system of the laser cutting machine, ensuring that the guide rail system can withstand high loads and maintain precise movement. The second guide rail mounting plate 4 is welded and fixed along the Y-direction of the beam body and also has a step. The step design of the second guide rail mounting plate 4 ensures the stability and precision of the guide rail system under high load operation, allowing the guide rail to be accurately installed and fixed on the beam, avoiding the risk of guide rail displacement or deformation, and further improving the working precision and stability of the laser cutting machine. The design of these two guide rail mounting plates ensures the reliability and stability of the laser cutting machine's guide rail system, reduces vibration and errors during operation, improves the precision and efficiency of the laser cutting machine during high-speed cutting, and extends the service life of the equipment.

[0039] A laser cutting machine includes a bed and a laser cutting machine beam. An X-axis drive mechanism is mounted on the bed, and the moving part of the X-axis drive mechanism is connected to the end of the beam body. A laser head module is mounted on the beam body. This structural design, through the connection between the X-axis drive mechanism and the beam body, ensures precise movement of the laser cutting machine in the X-axis direction and stability during the cutting process. The X-axis drive mechanism drives the beam body to move along the X-axis on the bed, enabling the laser head to be accurately positioned and cut within the working area. The laser head module mounted on the beam body carries the laser cutting head and is responsible for performing the laser cutting task.

[0040] By connecting the moving part of the X-axis drive mechanism to the end of the crossbeam body, a highly efficient and stable transmission system is formed, capable of quickly responding to motion commands and precisely controlling the movement of the crossbeam along the X-axis. The stable installation and movement of the head module ensures that the laser cutting machine maintains high precision and high speed during complex cutting operations. This design effectively improves the working efficiency of the laser cutting machine, reduces mechanical motion errors, and guarantees high precision and stability during long-term use.
