Technical Field

[0001] The utility model relates to the technical field of cutting auxiliary accessories, in particular to an auxiliary positioning mechanism of a laser cutting machine. Background Art

[0002] The laser cutting machine is a high-precision, high-efficiency processing equipment that uses the laser emitted by the laser to focus into a high-power density laser beam through the optical path system. When the laser beam is irradiated to the surface of the workpiece, it can make the workpiece reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam will blow away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material will eventually form a slit, thereby achieving the purpose of cutting. Before cutting the workpiece, the laser cutting machine needs to position the workpiece. Most of the current auxiliary positioning mechanisms are fixed, which makes it difficult to position extremely complex or irregularly shaped workpieces, and has poor stability, which affects operation.

By designing the telescopic cylinder 40 on the fixed side seat 20, its piston rod 41 is connected to the movable clamping seat 30, so that the movable clamping seat 30 can perform telescopic movement as needed, and can realize rapid clamping and release of the workpiece, thereby improving work efficiency and reducing the difficulty of operation. The positioning screw 31 and the rotating disk 32 installed on the top of the movable clamping seat 30 make the positioning more precise. The height of the positioning screw 31 can be adjusted by rotating the rotating disk 32, thereby achieving stable clamping of workpieces of different thicknesses. It can adapt to workpieces of different sizes and shapes, and improves the flexibility and adaptability of positioning.

[0031] Furthermore, a grid plate 11 is embedded in the center of the top surface of the auxiliary positioning platform 10, and the top surface of the auxiliary positioning platform 10 is flush with the top surface of the grid plate 11, which not only enhances the load-bearing capacity of the auxiliary positioning platform, but also facilitates the rapid cleaning of waste generated during the processing.
