Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, specifically to a laser cutting machine worktable structure. Background Technology

[0002] Laser cutting involves focusing a laser beam emitted from a laser source into a high-power-density beam via an optical path system. This beam irradiates the workpiece surface, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas, coaxial with the beam, blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a kerf is eventually formed in the material, thus achieving the purpose of cutting.

[0003] In the existing technology, the worktable of a laser cutting machine consists of a bed, a support beam set on the inner side of the bed, and a support toothed plate inserted on the support beam, which is used to support and carry the workpiece for cutting. During the workpiece cutting process, because the bed is equipped with driving components (such as motors, cylinders, hydraulic cylinders, etc.), the bed is prone to vibration when it is in operation. This causes the workpiece carried on the support toothed plate to shift, affecting the processing accuracy, which needs further development and improvement. Utility Model Content

[0004] The purpose of this invention is to provide a laser cutting machine worktable structure to solve the problem that the workpiece supported on the worktable is prone to displacement when the laser cutting machine is cutting the workpiece, which affects the cutting accuracy.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: A laser cutting machine workbench structure includes a bed body. Two support mounting beams are symmetrically arranged longitudinally between the inner surfaces of the two transverse sides of the bed body. Several support toothed plates are equidistantly inserted between the tops of the support mounting beams. Two support mounting plates are symmetrically arranged transversely between the support mounting beams. Limiting mechanisms are provided at both ends of the longitudinal direction between the support mounting plates. The limiting mechanisms include two sliding mounting plates, each located at the bottom of one longitudinal end of the two support mounting plates. The sliding mounting plates are slidably connected to the support mounting plates longitudinally. The sliding mounting plates are inserted into the support mounting beams. A support mounting rod is provided between the ends of the sliding mounting plates that are longitudinally away from the support mounting beams. A limiting rod is vertically installed between the support toothed plates on the support mounting rod. A telescopic device is provided at the bottom of the support mounting beam directly below the sliding mounting plate at one transverse end. A connecting block is installed at the output end of the telescopic device. The connecting block is connected to one longitudinal end of the bottom of the sliding mounting plate.

[0006] Furthermore, the support mounting plate is located directly below the support toothed plate.

[0007] Furthermore, the cross-section of the support mounting plate, when vertically cut along the transverse direction, is a triangular structure.

[0008] Furthermore, the two inclined surfaces at the top of the support mounting plate are provided with a splash-proof protective layer made of graphite plate material.

[0009] Furthermore, the bed body and the support mounting beam, one end of the support mounting plate and the bed body, the support mounting plate and the support mounting beam, the sliding mounting plate and the support mounting rod, and the support mounting rod and the limiting rod are all fixedly connected by welding.

[0010] Furthermore, the bottom of the support mounting plate is provided with a rectangular slide rail along the longitudinal direction, and the top of the sliding mounting plate is provided with a rectangular slide groove that matches the rectangular slide rail. The rectangular slide rail is embedded in the rectangular slide groove to form a sliding connection.

[0011] Furthermore, the connection between the limiting rod and the supporting mounting rod is provided with a triangular reinforcing rib, and the two right-angled sides of the triangular reinforcing rib are fixedly connected to the outer surfaces of the limiting rod and the supporting mounting rod, respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the utility model has a reasonable design, simple and stable structure, and strong practicality; through the limiting mechanism set at both ends of the bed, the sliding mounting plate and the connected support mounting rod and limiting rod are driven to move longitudinally by the telescopic device, which can implement stable fixed limiting from both ends of the workpiece, effectively offset the vibration of the equipment operation, prevent the workpiece displacement, and thus significantly improve the cutting accuracy; this layout makes the limiting structure and the driving component located below the supporting tooth plate, which not only cleverly avoids the sputtering erosion of the laser cutting area and improves the durability of key components, but also does not hinder the smooth fall of cutting waste through the gap of the tooth plate, making it suitable for widespread use.

[0017] Combination Figs. 1 to 3 The laser cutting machine worktable structure shown includes a bed body 1. Two support mounting beams 2 are symmetrically arranged longitudinally between the inner surfaces of the two transverse sides of the bed body 1. Several support toothed plates 3 are equidistantly inserted and installed transversely between the tops of the support mounting beams 2. Two support mounting plates 4 are symmetrically arranged transversely between the support mounting beams 2. Limiting mechanisms 5 are provided at both ends of the longitudinal direction between the support mounting plates 4. Each limiting mechanism 5 includes two sliding mounting plates 501, each sliding mounting plate 501 being located at the bottom of one longitudinal end of a support mounting plate 4. The sliding mounting plate 501 and the supporting mounting plate 4 are slidably connected in the longitudinal direction. The sliding mounting plate 501 and the supporting mounting beam 2 are plugged in. A supporting mounting rod 502 is provided between the longitudinal ends of the sliding mounting plate 501 and the supporting mounting beam 2. A limit rod 503 is vertically installed between the supporting tooth plates 3. A telescopic device 504 is provided at the bottom of the supporting mounting beam 2 directly below the sliding mounting plate 501 in the lateral direction. A connecting block is installed at the output end of the telescopic device 504. The connecting block is connected to the longitudinal end of the bottom of the sliding mounting plate 501.

[0018] The support mounting plate 4 is located directly below the support toothed plate 3. The cross-section of the support mounting plate 4, cut vertically along the horizontal direction, is triangular to avoid interfering with the recycling of waste material from cutting, as it is positioned between the support toothed plates 3. Simultaneously, the triangular cross-section design of the support mounting plate 4 facilitates waste material guiding operations to a certain extent. The two inclined surfaces at the top of the support mounting plate 4 are provided with a graphite-based anti-splash protective layer, which protects the support mounting plate 4 and extends its service life. The bed body 1 and the support mounting beam 2, one end of the support mounting plate 4 and the bed body 1, the support mounting plate 4 and the support mounting beam 2, the sliding mounting plate 501 and the support mounting rod 502, and the support mounting rod 502 and the limiting rod 503 are all fixedly connected by welding, ensuring the stability and robustness of the interconnected structures and improving service life. The lifespan and safety of the device are ensured by the following: A rectangular slide rail is longitudinally arranged at the bottom of the support mounting plate 4, and a rectangular groove is provided at the top of the sliding mounting plate 501 to match the rectangular slide rail. The rectangular slide rail is embedded in the rectangular groove to form a sliding connection, ensuring the smooth sliding of the sliding mounting plate 501. A triangular reinforcing rib is provided at the connection between the limiting rod 503 and the support mounting rod 502. The two right-angled sides of the triangular reinforcing rib are fixedly connected to the outer surfaces of the limiting rod 503 and the support mounting rod 502, respectively, further improving the stability and firmness of the limiting rod 503's own position structure and preventing breakage at the connection point. Two telescopic devices 504 are staggered to avoid mutual interference. The telescopic device 504 is electrically connected to the laser cutting machine control center to control its working state. The telescopic device 504 can be a cylinder, hydraulic cylinder, or electric telescopic rod, which can be selected according to actual usage requirements.

[0019] Working principle: In use, the workpiece to be cut is placed on the upper part of the support toothed plate, and then the telescopic device is controlled to work. The output end of the telescopic device drives the sliding mounting plate to move longitudinally through the connecting block. Since the sliding mounting plate and the support mounting rod are fixedly connected by welding, and the support mounting rod is vertically mounted with limit rods, the longitudinal movement of the sliding mounting plate will synchronously drive the support mounting rod and its limit rods to move longitudinally along the bed. The limit rods in the limit mechanism located at both ends of the bed move towards each other, approaching the workpiece from both ends and finally tightly abutting the workpiece to be cut. Through the clamping action of the limit rods at both ends, the workpiece is firmly restricted on the support toothed plate, effectively preventing the workpiece from shifting or moving, thereby ensuring the accuracy of the relative position of the laser beam and the workpiece and improving the cutting accuracy. The triangular cross-section design of the support mounting plate and the graphite plate anti-splash protection layer covering it further protect the components below from the corrosion of falling high-temperature debris and splashes, improving the durability and service life of the components. At the same time, the waste generated during cutting can fall smoothly through the gaps in the support toothed plate, completing the collection and cleaning of waste without affecting continuous operation.

[0020] After the cutting operation is completed, the telescopic device moves forward, pushing the sliding mounting plate, support mounting rod and limit rod to move in the opposite direction, loosening the fixation on the workpiece, making it easier to unload the processed workpiece and place a new workpiece to be processed.
