Description

Technical Field

[0001] The utility model relates to the technical field of workpiece positioning, in particular to a positioning device for laser cutting. Background Art

[0002] Laser cutting uses a focusing mirror to focus the laser beam on the surface of the material to melt the material, and at the same time uses compressed gas coaxial with the laser beam to blow away the melted material, and makes the laser beam and the material move relative to each other along a certain trajectory, thereby forming a certain shape of the cut. Laser cutting technology is widely used in the processing of metal and non-metal materials, which can greatly reduce processing time, reduce processing costs, and improve workpiece quality.

The utility model achieves a good fixing effect on the plate by setting a workbench, a placement rack, a positioning mechanism, a rotating shaft, a first bevel gear, a rotating rod, a second bevel gear, a clamping plate, a support plate, a sliding seat, a slide groove and an external thread, thereby avoiding displacement of the plate during the cutting process, improving the cutting quality of the plate, and being able to fix plates of different thicknesses, with a wide range of uses.
