Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, specifically a gantry-type laser cutting machine crossbeam. Background Technology

[0002] A laser cutting machine uses a laser beam emitted from a laser source, which is focused into a high-power-density laser beam through an optical path system. This laser beam irradiates the workpiece surface, causing the workpiece to reach its melting or boiling point. As the relative position of the beam and the workpiece moves, a kerf is formed in the material, thus achieving the cutting purpose. The gantry laser cutting machine is a highly efficient and precise cutting device widely used in the metal processing field. Its name comes from its structural feature—a gantry frame design, consisting of a supporting frame on both sides and a crossbeam spanning it. The laser cutting head moves along the crossbeam and longitudinal tracks, thereby achieving the cutting of metal materials.

[0003] The crossbeam of a gantry laser cutting machine typically refers to the structural part that supports the laser head and cutting platform. It plays a crucial role throughout the cutting process, ensuring the cutting head can move smoothly along the X-axis for precise laser cutting. However, most existing gantry laser cutting machine crossbeams are inconvenient for vertical position adjustment, cannot meet diverse usage needs, and lack practicality. Therefore, this paper proposes a new type of gantry laser cutting machine crossbeam to address these issues. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figures 1-4As shown, a gantry laser cutting machine crossbeam includes a crossbeam 2, and bases 1 are fixedly installed on both the left and right sides of the bottom of the crossbeam 2.

[0028] The crossbeam 2 has a T-shaped inner groove 16 at its center. A moving component is installed inside the inner groove 16. A sliding groove 3 is provided on the front surface of the inner groove 16. The front surface of the sliding groove 3 extends to the outside of the crossbeam 2. A slider 6 is slidably connected inside the sliding groove 3. The slider 6 is installed with the moving component.

[0029] The slider 6 has an internal mounting groove 14, the front surface of which extends to the outside of the slider 6. The laser cutting machine body 7 is mounted inside the mounting groove 14 via an adjustment component. During operation, the two bases 1 are installed with the external sliding rail, allowing the crossbeams 2 on the two bases 1 to move along the Y-axis to cut the product at different positions. The moving component on the crossbeam 2 can drive the slider 6 to slide inside the slide groove 3, allowing the laser cutting machine body 7 mounted inside the slider 6 to move and cut along the X-axis. At the same time, the height of the laser cutting machine body 7 in the mounting groove 14 inside the slider 6 can be adjusted via the adjustment component to accommodate different products for cutting. This allows the crossbeam 2 to meet more usage needs and is highly practical.

[0030] The slide 3 has through slots 10 on both its upper and lower surfaces. A guide block is slidably connected inside the through slot 10 on the lower surface. The top of the guide block is fixedly connected to the bottom of the slider 6. The top of the adjustment component passes through the through slot 10 on the upper surface. During operation, the movement of the slider 6 is limited by the sliding of the guide block inside the through slot 10 on the lower surface, making the movement of the laser cutting machine body 7 driven by the slider 6 more stable. At the same time, the through slot 10 on the upper surface allows the adjustment component to pass through and meet the usage requirements of the adjustment component.

[0031] The moving component includes a motor 15 fixedly installed on the left side inside the inner groove 16. A threaded rod 4 is fixedly connected to the output end of the motor 15. The right end of the threaded rod 4 extends to the right side of the crossbeam 2. The threaded rod 4 and the crossbeam 2 are rotatably connected via bearings. An internal threaded sleeve is threadedly connected to the outer surface of the threaded rod 4. The outer surface of the internal threaded sleeve is fixedly connected to the slider 6. During operation, the motor 15 is energized to drive the threaded rod 4 to rotate. The rotation of the threaded rod 4 drives the internal threaded sleeve, which is threaded to it, to move within the sliding groove 3 via the slider 6, thus moving the slider 6. Simultaneously, the forward and reverse rotation of the motor 15 allows the slider 6 to move left and right within the sliding groove 3, and causes the laser cutting machine body 7 to move left and right along the X-axis for cutting.

[0032] The adjustment assembly includes limiting grooves 11 on the left and right sides inside the mounting groove 14. Limiting blocks 13 are slidably connected inside the limiting grooves 11. The laser cutting machine body 7 is mounted to the rear of its outer surface with the two limiting blocks 13. A hydraulic cylinder 5 is installed at the top of the crossbeam 2. The output end of the hydraulic cylinder 5 extends through a through groove 10 on the upper surface into the mounting groove 14. The output end of the hydraulic cylinder 5 is fixedly connected to the top of the laser cutting machine body 7 inside the mounting groove 14. During operation, the hydraulic cylinder 5 drives the laser cutting machine body 7 inside the slider 6 to slide within the mounting groove 14. The laser cutting machine body 7 is limited by the limiting blocks 13 within the limiting grooves 11 during sliding. The sliding mechanism makes the laser cutting machine body 7 more stable when adjusting its vertical height, ensuring that it remains perpendicular to the product to be cut after adjustment. This also allows for easy vertical height adjustment of the crossbeam 2 to accommodate different products, meeting various usage needs and enhancing practicality. Simultaneously, the top of the hydraulic cylinder 5, through the upper surface groove 10, is positioned on top of the crossbeam 2 and moves with the slider 6. The crossbeam 2 also limits the movement of the hydraulic cylinder 5, allowing it to slide within the mounting groove 14 inside the slider 6 for adjustment.

[0033] The bottom of the hydraulic cylinder 5 is attached to the bottom of the crossbeam 2, and the two limiting blocks 13 are respectively attached to the left and right sides of the laser cutting machine body 7 inside the mounting groove 14. During operation, the hydraulic cylinder 5 can move on the top of the crossbeam 2 along with the slider 6, and the limiting blocks 13 can be separated and disassembled from the laser cutting machine body 7.

[0034] The limiting block 13 has a mounting bolt 12 running through it. One end of the mounting bolt 12 is threadedly connected to the inside of the mounting groove 14 of the laser cutting machine. During operation, the limiting block 13 is fixedly installed to the laser cutting machine body 7 by the mounting bolt 12. The laser cutting machine body 7 inside the mounting groove 14 can be disassembled and separated from the limiting block 13 by rotating the mounting bolt 12, which facilitates the disassembly and maintenance of the laser cutting machine body 7.

[0035] A protective cover 8 is fixedly installed on the lower outer surface of the laser cutting machine body 7. A connecting pipe 9 is fixedly installed on the lower right side of the protective cover 8, and the connecting pipe 9 communicates with the interior of the protective cover 8. During operation, the protective cover 8 fixedly installed on the lower outer surface of the laser cutting machine body 7 can protect the cutting head of the laser cutting machine body 7 during cutting and prevent splatter from flying everywhere. At the same time, the connecting pipe 9 can be connected to an external dust collection device to absorb the smoke and dust inside the protective cover 8 and prevent the smoke and dust from flying everywhere, thus providing a certain degree of protection for the air and the workers.
