[0002] Laser cutting uses a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature, evaporated to form holes, and as the beam moves on the material, the holes continuously form a very narrow slit to complete the cutting of the material. The laser cutting machine fixture is a device used to keep the position of the workpiece stable during the laser cutting process. In laser cutting technology, the fixture is an important device to ensure stable and precise cutting of the workpiece. At present, the mainstream laser cutting machine fixtures on the market mostly use mechanical fixtures or vacuum adsorption to fix the workpiece. Although these methods can meet the fixing needs to a certain extent, the mechanical fixture may cause scratches on the workpiece surface due to improper operation, affecting the product quality; and the vacuum adsorption method is limited by the flatness and adsorption force of the workpiece surface, and the fixing effect is not ideal for non-planar or rough workpieces.

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a laser cutting machine fixing device. Figure 1, including a positioning slide post 1, two positioning slide posts 1 are provided, a group of sliding frames 3 are provided on the two positioning slide posts 1, a support rod 2 is detachably provided between the two sliding frames 3, a cylinder 16 is fixed to the middle of the ends of the two support rods 2 away from each other, and the ends of the cylinder 16 and the positioning slide post 1 are connected with a fixing part 6, and a plurality of connecting holes are evenly distributed along the circumferential direction on the surface of the fixing part 6, and the positioning of the positioning slide post 1 and the cylinder 16 can be completed by fixing the fixing part 6.

[0020] like Figure 2 As shown, an adjustment hole 4 is opened inside the sliding frame 3, and an inner sliding block 7 is fixedly installed on the inner wall of the adjustment hole 4. The inner sliding block 7 is slidably connected to the positioning sliding column 1, so when the cylinder 16 works, it can push the support rod 2 to slide on the positioning sliding column 1 to adjust the distance.

[0021] Combination Figure 3 As shown, a connecting base plate 5 is welded to the bottom end of the sliding frame 3, and a movable clamping frame 14 is rotatably connected to the bottom end of the connecting base plate 5. The movable clamping frame 14 is arranged in a V shape, and positioning pulleys 15 are movably connected to both ends of the movable clamping frame 14. The side wall of the workpiece can be clamped and limited by the positioning pulley 15.

[0022] In addition, mounting blocks 12 are fixedly installed at both ends of the support rod 2, and a fixing hole 13 is opened at the center of the top of the mounting block 12. A clamping mechanism is provided on the sliding frame 3, and the clamping mechanism includes a connecting plate 8 provided on the support rod 2, and a limiting piece 11 fixed to the side wall of the connecting plate 8. A positioning bolt 9 is threadedly connected at the center of the connecting plate 8;

[0023] When the positioning bolt 9 is tightened, one end of the positioning bolt 9 can be pushed to extend into the fixing hole 13 to position it, and a baffle 10 is welded to one side of the bottom of the connecting plate 8 as an integral structure. At this time, the baffle 10 and the limiting plate 11 can limit the edge of the mounting block 12 to improve protection.

[0024] The implementation principle of a laser cutting machine fixing tooling of the embodiment of the present application is as follows: when in use, first fix the fixing member 6 on the cutting table by screws, so as to complete the positioning of the positioning slide column 1 and the cylinder 16. When cutting, the support rod 2 can be pre-mounted on the connecting base plate 5, and then the mounting block 12 and the connecting base plate 5 are fixed by the positioning bolts 9 passing through the fixing holes 13, so as to complete the installation of the support rod 2. At the same time, the baffle 10 and the limiting plate 11 can limit the external position of the mounting block 12, and then the workpiece is placed between the two support rods 2, and then the cylinder 16 is started. 16 works and its output end pushes the two support rods 2 to move closer to or away from each other. At this time, the inner slide block 7 inside the sliding frame 3 slides on the positioning slide column 1, and then pushes the connecting base plates 5 on both sides to move closer to the workpiece. During the adjustment process, the movable clamping frame 14 rotates at the bottom of the connecting base plate 5. It is suitable for workpieces of different shapes and sizes, and can meet the diverse needs of different users. It contacts the outer wall of the workpiece through the positioning pulley 15. When the two support rods 2 are close to each other, the positioning pulley 15 can be pushed to fit closely with the outer wall of the workpiece, thereby achieving a good fixing effect.
