Description

Technical Field

[0001] The utility model relates to the field of cutting machines, in particular to a laser cutting machine which is easy to position. Background Art

[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, the 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 slit is eventually formed in the material, thereby achieving the purpose of cutting. The optical cutting process replaces the traditional mechanical knife with an invisible beam. It has the characteristics of high precision, fast cutting, no limitation on cutting pattern, automatic typesetting to save materials, smooth incision, low processing cost, etc. It will gradually improve or replace the traditional metal cutting process equipment.

[0003] Existing laser cutting machines are inconvenient for positioning the workpiece to be cut. They can only be clamped and positioned from both sides of the workpiece, but cannot be positioned from multiple directions. This can easily cause the workpiece to shift in the direction where there is no positioning structure, causing the workpiece to be misaligned. It is also inconvenient to replace the cutting gas absorption filter material, making it inconvenient to use. Utility Model Content

[0024] By providing a positioning component 4 located inside the placement groove 3, after the workpiece is placed, the positioning component 4 is operated to clamp and fix the workpiece from the left and right sides, and then the positioning component 4 is operated to clamp and fix the workpiece from the front and back sides of the workpiece to avoid the workpiece from shifting in the forward and rearward directions. The positioning component 4 positions the workpiece by clamping, which is convenient for positioning workpieces of different sizes and has strong applicability. At the same time, the suction component 5 is provided to suction and filter the gas generated during the cutting process. The suction component 5 is easy to disassemble, thereby facilitating the replacement of the internal filter material and improving the convenience of use.

[0025] like Figure 2 and Figure 3 As shown, the positioning assembly 4 includes a fixing frame 41, which is fixedly installed on the inner side of the placement groove 3, a two-way threaded rod 42 is rotatably installed inside the fixing frame 41, a driving motor 43 connected to the two-way threaded rod 42 is fixedly installed on the left side of the laser cutting machine body 1, a sliding seat 44 is threadedly connected to the left and right sides of the outside of the two-way threaded rod 42, a positioning plate 45 is fixedly connected to the top of the sliding seat 44, a rib plate 46 is fixedly installed on the outer side of the positioning plate 45, and a lateral positioning mechanism 47 is movably installed inside the positioning plate 45.

[0026] The lateral positioning mechanism 47 includes a bidirectional threaded rod 471 and a drive motor 472. The bidirectional threaded rod 471 is rotatably installed inside the positioning plate 45, and the drive motor 472 is fixedly installed on the outside of the positioning plate 45. The outside of the output shaft of the drive motor 472 is fixedly installed with a bevel gear 473 located in the positioning plate 45.

The front and rear sides of the outside of the bidirectional threaded rod 471 are both threadedly connected with a sliding plate 475, and the outside of the sliding plate 475 is fixedly connected with a positioning plate 476.

[0027] The bidirectional threaded rod 42 is driven to rotate by controlling the driving motor 43, and the sliding seat 44 on the left and right sides of the fixed frame 41 is driven to move inward by the rotation of the bidirectional threaded rod 42, and the positioning plate 45 is driven to move inward by the sliding seat 44 to clamp the workpiece from the left and right. At the same time, the bevel gear 473 is driven to rotate by controlling the driving motor 472, and the bidirectional threaded rod 471 is driven to rotate by the bevel gear 474 meshing with the bevel gear 473. The sliding plates 475 of the front and rear parts are driven to move inward by the rotation of the bidirectional threaded rod 471, and the positioning plate 476 is driven to move inward by the sliding plate 475 to clamp and fix the workpiece from the front and rear sides.

[0029] The gas generated during the cutting process of the workpiece is sucked into the serpentine tube 52 from the suction hood 53 by opening the vacuum fan 54, and enters the interior of the suction box 51 through the serpentine tube 52. The gas is adsorbed by the activated carbon adsorbent arranged in the card frame 56 and then discharged through the vacuum fan 54. After long-term use, the cover plate 57 can be removed by removing the fixing bolts 58, and the internal filter material can be replaced by pulling the card frame 56 outward along the card rail 55, thereby improving the convenience of use.

[0037] The activated carbon filter material is provided to filter and adsorb the gas entering the suction box 51, thereby reducing the direct discharge of irritating gas.

[0038] The following is a detailed description of the working principle of this easy-to-position laser cutting machine.

[0039] like Figures 1 to 5 As shown, by setting the workpiece inside the placement groove 3, and controlling the driving motor 1 43 to drive the bidirectional threaded rod 1 42 to rotate, the bidirectional threaded rod 1 42 is rotated to drive the sliding seats 44 on the left and right sides of the fixed frame 41 to move inward, and the sliding seats 44 drive the positioning plate 1 45 to move inward to clamp the workpiece from the left and right, and at the same time, the bevel gear 1 473 is driven to rotate by controlling the driving motor 2 472, and the bevel gear 2 474 meshing with the bevel gear 1 473 is used to drive the bidirectional threaded rod 2 471 to rotate, and the sliding plates 475 of the front and rear parts are driven to move inward by the rotation of the bidirectional threaded rod 2 471, and the positioning plate 2 is driven by the sliding plate 475. 476 moves inward to clamp and fix the workpiece from the front and rear sides. By clamping the workpiece from the front, back, left and right, the positioning and fixing effect is improved to prevent the workpiece from shifting. The metal vapor and gas generated during the cutting process of the workpiece are sucked into the serpentine tube 52 from the suction hood 53 through the opening of the vacuum fan 54, and enter the interior of the suction box 51 through the serpentine tube 52. The metal vapor and gas are adsorbed by the activated carbon adsorbent provided in the card frame 56 and then discharged through the vacuum fan 54. After long-term use, the cover plate 57 is removed by removing the fixing bolts 58, and the internal filter material is replaced by pulling the card frame 56 outward along the card rail 55.

[0040] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
