Abstract
Description
Technical Field
[0001] This utility model relates to the field of beam technology, and in particular to a lightweight, high-intensity laser machine beam structure. Background Technology
[0002] According to Chinese Publication No. CN221791412U, a laser cutting machine crossbeam includes a crossbeam body, a locking block, and a control compartment. The locking block is connected to the bottom of the crossbeam body, and a connecting block is fitted into the locking block. A control compartment is formed within the crossbeam body, and a lead screw is installed inside the control compartment. A ball bearing sleeve is threaded onto the surface of the lead screw, and a machine head is connected to the ball bearing sleeve. A connecting plate is connected to the machine head. A slide rail is provided on the crossbeam body, and a slider is slidably connected to the slide rail. An electric telescopic rod is installed on the top of the slider. This invention inserts the locking block at the bottom of the crossbeam body into the connecting block and fixes it with mounting bolts, facilitating the connection and disassembly of the crossbeam body and making subsequent maintenance of the crossbeam more convenient. The electric telescopic rod drives a limiting post on a limiting plate to rise and move into a limiting hole on the connecting plate, thereby connecting the slider to the machine head. When disassembling and maintaining the machine head, the electric telescopic rod is activated to move the limiting post out of the limiting hole, making disassembly convenient.
[0003] The aforementioned technologies and existing crossbeams are typically integrally molded structures, with the internal honeycomb core and cavity arrangement fixed during the manufacturing stage. Once formed, if the rigidity of the crossbeam needs to be increased during subsequent use, it can often only be achieved by replacing the entire crossbeam or welding additional reinforcing plates. This is not only costly but also compromises the original precision and cannot quickly improve the overall rigidity of the crossbeam. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot quickly improve the overall rigidity of the crossbeam, and to propose a lightweight, high-strength laser machine crossbeam structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lightweight high-intensity laser machine crossbeam structure, comprising a crossbeam body, two machine bases at the bottom of the crossbeam body, a honeycomb core inside the crossbeam body, stiffening ribs arranged horizontally on the top of the honeycomb core, guide rails at both ends of the bottom surface of the stiffening ribs, fixing blocks on both sides of the crossbeam body, two reinforcing blocks on the top of the fixing blocks, silicone pads on the top of the reinforcing blocks, a blocking block on one side of each of the two reinforcing blocks, guide grooves on both sides of the reinforcing blocks, fixing holes on the top surface of the two fixing blocks and the two end surfaces of the reinforcing blocks, fixing bolts on the top of each fixing hole, and limiting blocks on both sides of the two fixing holes on the top surface of the fixing blocks.
[0006] Preferably, both of the bases are installed on the bottom surfaces at both ends of the crossbeam body, and both bases are welded to the crossbeam body. The two fixing blocks are mirror images of the crossbeam body, and both fixing blocks are welded to the bases.
[0007] Preferably, the two fixing holes on the top surface of the two fixing blocks are horizontal, and the positions of the fixing holes on the two ends of the reinforcing block correspond one-to-one with the positions of the fixing holes on the top surface of the fixing block. Both ends of the two reinforcing blocks are fixed to the top surface of the two fixing blocks by fixing bolts.
[0008] Preferably, the limiting blocks on both sides of the two fixing holes on the top surface of the two fixing blocks are mirror images of each other with the fixing holes as the center, and the limiting blocks are integrally formed with the fixing blocks.
[0009] Preferably, the two blocking blocks on one side of the two reinforcing blocks are horizontal with the reinforcing blocks, and the two blocking blocks are installed on the top surface of the fixing block on one side of the crossbeam body. The two blocking blocks are located in the middle of every two limiting blocks.

The honeycomb core is cross-shaped and welded to the crossbeam body. The stiffening ribs at the top of the honeycomb core are arranged in a horizontal array on the inner surface of the top of the crossbeam body. The stiffening ribs are welded to the honeycomb core and the crossbeam body. The two guide rails on the bottom surface of the stiffening ribs are welded to the stiffening ribs, and the positions of the guide rails correspond one-to-one with the positions of the two reinforcing blocks.
[0012] Beneficial effects In this invention, a cross-shaped honeycomb core and stiffening ribs are arranged inside the main body of the crossbeam to form a supporting frame. Fixing blocks are welded to the sides of the base at both ends of the crossbeam for installing pluggable reinforcing blocks. Guide grooves are provided on both sides of the reinforcing blocks for sliding into and positioning them in the cavity above the honeycomb core along the internal guide rails of the crossbeam. Limiting blocks and blocking blocks provide guidance and prevent displacement. After the reinforcing blocks are installed, both ends are fixed to the fixing blocks with fixing bolts, forming a support with the stiffening ribs and honeycomb core. This improves the bending and torsional stiffness of the crossbeam, achieving adjustable reinforcement of the crossbeam stiffness and solving the problem of not being able to quickly improve the overall stiffness of the crossbeam body.

[0015] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0016] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1: Reference Figure 1-6A lightweight, high-intensity laser machine crossbeam structure includes a crossbeam body 1, with two bases 2 at the bottom of the crossbeam body 1. The crossbeam body 1 has a honeycomb core 10 inside, and horizontally arranged stiffening ribs 11 on the top of the honeycomb core 10. Guide rails 12 are provided at both ends of the bottom surface of the stiffening ribs 11. Fixing blocks 3 are provided on both sides of the crossbeam body 1. Two reinforcing blocks 6 are provided on the top of the fixing blocks 3, and silicone pads 7 are provided on the top of the reinforcing blocks 6. A blocking block 5 is provided on one side of each of the two reinforcing blocks 6. Guide grooves 13 are provided on both sides of the reinforcing blocks 6. Fixing holes 8 are provided on the top surface of the fixing block 3 and both ends of the reinforcing block 6. Fixing bolts 9 are provided on the top of each fixing hole 8. Limiting blocks 4 are provided on both sides of the two fixing holes 8 on the top surface of the fixing block 3. The two bases 2 are installed on the bottom surfaces of both ends of the crossbeam body 1 and are welded to the crossbeam body 1. The two fixing blocks 3 are mirror images of the crossbeam body 1 and are welded to the bases 2. The two fixing holes 8 on the top surface of the two fixing blocks 3 are horizontal, and the positions of the fixing holes 8 on both ends of the reinforcing block 6 are the same as the positions of the fixing holes 8 on the top surface of the fixing block 3. In a one-to-one correspondence, both ends of the two reinforcing blocks 6 are fixed to the top surfaces of the two fixing blocks 3 by fixing bolts 9. The limiting blocks 4 on both sides of the two fixing holes 8 on the top surfaces of the two fixing blocks 3 are mirror images of each other with the fixing holes 8 as the center, and the limiting blocks 4 are integrally formed with the fixing blocks 3. The two blocking blocks 5 on one side of the two reinforcing blocks 6 are horizontal with the reinforcing blocks 6, and the two blocking blocks 5 are installed on the top surface of the fixing blocks 3 on one side of the crossbeam body 1. The two blocking blocks 5 are located in the middle of every two limiting blocks 4. The silicone pads 7 on the top of the two reinforcing blocks 6 are installed on the top of the reinforcing blocks 6. The surface of the crossbeam body 1 is hollow, and the honeycomb core 10 is installed in the cavity inside the crossbeam body 1. The honeycomb core 10 is cross-shaped and welded to the crossbeam body 1. The stiffening ribs 11 at the top of the honeycomb core 10 are arranged in a horizontal array on the inner wall surface of the top of the crossbeam body 1. The stiffening ribs 11 are welded to the honeycomb core 10 and the crossbeam body 1. The two guide rails 12 on the bottom surface of the stiffening ribs 11 are welded to the stiffening ribs 11. The positions of the guide rails 12 correspond one-to-one with the positions of the two reinforcing blocks 6.
[0018] The main body 1 of the crossbeam is an integral load-bearing frame with a hollow internal structure, providing space for the installation of the honeycomb core 10 and stiffening ribs 11, while also bearing the main bending and torsional moments of the entire crossbeam. The honeycomb core 10 is arranged in a cross-shaped pattern within the internal cavity of the crossbeam, forming a support structure through welding to the four inner walls of the crossbeam (top, bottom, left, and right), enhancing the crossbeam's resistance to deformation both longitudinally and laterally. The honeycomb core 10 divides the internal cavity into four independent chambers, making the stress distribution of the crossbeam more uniform under load and preventing localized deformation concentration. Stiffening ribs 11 are welded to the top of the honeycomb core 10, horizontally arrayed along the length of the crossbeam. Through welding to the honeycomb core 10 and the inner walls of the crossbeam, the longitudinal forces and torques from external loads are evenly transmitted to the honeycomb core 10 and the crossbeam walls, thereby improving the overall bending and torsional stiffness of the crossbeam. Guide rails 12 are welded to both ends of the bottom of the stiffening ribs 11, guiding the reinforcing blocks 6 so that they can slide along a fixed trajectory during insertion and removal. The reinforcing block 6 is a detachable rigid component with guide grooves 13 on both sides, which match the guide rail 12. During insertion, the sliding engagement between the guide grooves 13 and the guide rail 12 ensures the precise movement direction of the reinforcing block 6 inside the crossbeam, thereby guaranteeing the stability of the insertion positioning. A silicone pad 7 is provided on the top of the reinforcing block 6. The silicone pad 7 acts as a buffer and vibration damper when the reinforcing block 6 contacts the stiffening rib 11 or the inner wall of the crossbeam, preventing impacts caused by direct metal-to-metal contact and absorbing some energy during the high-frequency vibration of the crossbeam. A base 2 is welded to the bottom surface of both ends of the crossbeam body 1. The base 2 is the connection device between the crossbeam body 1 and the overall frame, providing installation and support, while also bearing the concentrated load from both ends of the crossbeam body 1 and transferring it to the equipment base, ensuring stable operation of the entire machine. A fixing block 3 is welded to the side of the base 2. The fixing block 3 provides installation for the reinforcing block 6 and bears the load of the reinforcing block 6. The bottom surface of the fixing block 3 is mounted on the machine body, and its top surface has two fixing holes 8 for engaging with the mounting holes at both ends of the reinforcing block 6 to install fixing bolts 9. Limiting blocks 4 are provided on both sides of the fixing hole 8. The limiting blocks 4 act as guides when the reinforcing block 6 is inserted. Through symmetrical limiting on both sides, the reinforcing block 6 can automatically align with the guide rail 12 during insertion, preventing insertion deviation. At the same time, it provides lateral limiting after the reinforcing block 6 is fully installed, preventing lateral displacement. A blocking block 5 is provided on one side of the reinforcing block 6. The blocking block 5 is installed on the top surface of the fixing block 3 on one side of the crossbeam body 1, located between every two limiting blocks 4. When the reinforcing block 6 slides into the end position along the guide rail 12, the blocking block 5 can limit its end, preventing the reinforcing block 6 from sliding excessively during insertion. After the reinforcing block 6 is inserted and in place, the fixing holes 8 at both ends of it are aligned with the fixing holes 8 on the top surface of the fixing block 3. The operator inserts the fixing bolt 9 and tightens it. The fixing bolt 9 locks the reinforcing block 6 and the fixing block 3 through thread locking, achieving a rigid connection.This device achieves lightweighting of the main beam 1 by designing a hollow cavity inside, and integrates a cross-shaped honeycomb core 10 as a support structure, thereby significantly enhancing the longitudinal and lateral deformation resistance of the beam. The stiffening ribs 11 above the honeycomb core 10 effectively and evenly transmit external loads to the beam wall and the honeycomb core 10, further improving the overall bending and torsional stiffness. Specific Implementation Example 2: Reference Figure 1-6 A lightweight, high-strength laser machine crossbeam structure, further based on the basic structure in Specific Embodiment 1, allows for the following: When the laser machine vibrates or the crossbeam is subjected to bending or torsional loads, the main body 1 of the crossbeam first bears the overall torque. The internal honeycomb core 10 disperses stress through a spatial cross structure, and stiffening ribs 11 transmit longitudinal and transverse stresses to the honeycomb core 10 and the crossbeam wall. Simultaneously, reinforcement blocks 6 provide reinforcement, further distributing the load evenly on both sides of the crossbeam. Silicone pads 7 act as buffers and vibration dampers throughout the process, absorbing instantaneous impact forces and reducing vibration amplitude. Reinforcing blocks 6 are mounted on the top surface of fixing blocks 3 via fixing bolts 9, ensuring that reinforcing blocks 6 will not loosen under high-frequency motion and complex load conditions. Fixing blocks 3 support reinforcing blocks 6 and bear their load. The base 2 is welded to the main body 1, stably supporting the entire crossbeam within the equipment frame.
[0020] In summary: 1. A cross-shaped honeycomb core 10 and stiffening ribs 11 are set inside the main body of the crossbeam to form a supporting frame. Fixing blocks 3 are welded to the sides of the base at both ends of the crossbeam for installing pluggable reinforcing blocks 6. The reinforcing blocks 6 have guide grooves 13 on both sides for sliding into and being positioned in the cavity above the honeycomb core 10 with the internal guide rails 12 of the crossbeam. The limiting blocks 4 and blocking blocks 5 are used to guide and prevent displacement. After the reinforcing blocks 6 are installed, the two ends of the reinforcing blocks 6 are fixed to the fixing blocks 3 by fixing bolts 9, so that they form a support with the stiffening ribs 11 and the honeycomb core 10, thereby improving the bending and torsional stiffness of the crossbeam and realizing the adjustable enhancement of the crossbeam stiffness. This solves the problem of not being able to quickly improve the overall stiffness of the main body of the crossbeam 1.
