Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, specifically to a worktable structure for a laser cutting machine. 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] Existing laser cutting machines typically use support plates on their worktables to support and support metal sheets. During the cutting process, the molten metal at the cutting point can easily cause the metal sheet to stick to the support plate, making it inconvenient to remove after the cutting is completed. This requires further development and improvement. Utility Model Content

[0004] The purpose of this invention is to provide a worktable structure for a laser cutting machine to solve the problem that during the cutting process of metal sheets on a laser cutting machine, the molten metal at the cutting part easily causes the metal sheet to stick to the supporting tooth plate, making it inconvenient to remove the metal sheet after the cutting process is completed.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a worktable structure for a laser cutting machine, comprising a worktable body, wherein a plurality of fixed support plates are equidistantly arranged longitudinally between the inner surfaces of the two sides of the worktable body, and a plurality of support toothed plates are equidistantly inserted between the tops of the fixed support plates. A first sliding mounting seat is provided on the inner surface of the worktable body on one side below the fixed support plates, and a rectangular slide groove is provided on the other side. The first sliding mounting seat is slidably connected longitudinally to the inner surface of the inner surface of the inner side ...

[0006] Furthermore, a circular limiting plate is provided between the workbench body and the operating handle on the rotating shaft. A limiting bolt is threaded along the axial direction of the circular limiting plate. One end of the limiting bolt passes through the circular limiting plate and contacts the outer surface of the workbench body on one side in the lateral direction.

[0007] Furthermore, the top material rod is a telescopic structure, including an outer tube connected to the rotating shaft, and an inner rod threadedly connected to the end of the outer tube away from the rotating shaft.

[0008] Furthermore, the inner rod at the end away from the outer tube includes a protective layer made of rubber, and the outer surface of the protective layer has anti-slip texture.

[0009] Furthermore, the outer surfaces of the rotating shaft and the top feed rod are covered with a ceramic protective coating to prevent metal droplet splashing.

[0010] Compared with the prior art, the advantages of this utility model are: the utility model has a reasonable design, simple and stable structure, and strong practicality; this structure realizes the compound motion control of the rotating shaft through the linkage design of the operating handle and the double sliding mounting base, accurately positioning it to the metal sheet adhesion area. The operating handle drives the rotating shaft to rotate, and the top material rod set on the rotating shaft impacts the metal sheet adhered to the support tooth plate, so as to realize the material picking operation of metal sheet cutting and processing. This integrated mechanical solution, while ensuring structural simplicity, creatively realizes the single-handle coordinated control of the "positioning-rotation-impact" action, which is suitable for widespread use.

[0013] 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.

Therefore, they should not be construed as limitations on this utility model.

[0015] Combination Figures 1 to 3 The worktable structure of a laser cutting machine shown includes a worktable body 1. Several fixed support plates 2 are equidistantly arranged longitudinally between the inner surfaces of the two sides of the worktable body 1. Several support toothed plates 3 are inserted and installed equidistantly between the tops of the fixed support plates 2. A first sliding mounting seat 4 is provided on the inner surface of the worktable body 1 on one side below the fixed support plates 2. The other side has a rectangular slide groove 5. The first sliding mounting seat 4 is slidably connected to the inner surface of the one side of the worktable body 1 longitudinally. A second sliding mounting seat 6 is slidably connected longitudinally between the top and bottom inner surfaces of the rectangular slide groove 5. Rotary bearings 7 are provided on the inner surface of the one side of the first sliding mounting seat 4 and the inner side of the second sliding mounting seat 6. A rotating shaft 8 is provided between the rotating bearings 7. One end of the rotating shaft 8 extends to the outside of the rectangular slide groove 5 and is equipped with an operating handle 9. Several top rods 10 are equidistantly arranged transversely on the outer circumference of the rotating shaft 8. The top rods 10 are arranged between the support toothed plates 3.

[0016] A circular limiting plate is provided between the worktable body 1 and the operating handle 9, with a limiting bolt threaded along its axial direction on the circular limiting plate. One end of the limiting bolt passes through the circular limiting plate and contacts the outer surface of the worktable body 1 on one side of the transverse direction, thereby limiting the longitudinal position of the rotating shaft 8. When not in use during normal cutting, it is moved to the longitudinal end of the worktable body 1. The ejector rod 10 is a telescopic structure, including an outer tube connected to the rotating shaft 8. An inner rod is threaded to the end of the outer tube away from the rotating shaft 8, allowing the overall length of the ejector rod 10 to be adjusted to accommodate metal sheet material handling operations at different positions. The end of the inner rod away from the outer tube includes a protective layer made of rubber with anti-slip texture on its outer surface, protecting the surface of the metal sheet and overcoming the problem of workpiece surface damage caused by rigid contact. The outer surfaces of the rotating shaft 8 and the ejector rod 10 are covered with a ceramic protective coating to prevent metal droplet splashing, improving the service life of the rotating shaft 8 and the ejector rod 10.

[0017] In use, the operator pulls the operating handle longitudinally. With the cooperation of the first and second sliding mounting seats, the rotating shaft is moved to the part where the metal sheet is attached to the support toothed plate through the coordinated action of the double guide rails. Then, the operating handle can be rotated, and the circumferential motion is converted into the radial impact of the ejector rod through the rotating shaft, so that the metal sheet is separated from the support toothed plate, so as to facilitate the material handling operation of the metal sheet.
