Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting chucks, in particular to a chuck for laser cutting with multiple groups of opposite controls. Background Art

[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 (such as about 0.1mm) cut to complete the cutting of the material.

[0003] The chuck is a mechanical device used to clamp the workpiece on the machine tool. It is a machine tool accessory that clamps and positions the workpiece by radial movement of the movable jaws evenly distributed on the chuck body. The chuck generally consists of three parts: the chuck body, the movable jaws and the jaw drive mechanism. The chuck body has a minimum diameter of 65 mm and a maximum of 1500 mm. There is a through hole in the center to allow the workpiece or bar to pass through. The back has a cylindrical or short conical structure, which is connected to the end of the machine tool spindle directly or through a flange.

[0004] When laser cutting a workpiece, a chuck is used to clamp and limit the workpiece to facilitate laser cutting.

[0005] The inventor discovered in his daily work that when the existing laser cutting chuck is in use, the multiple clamping blocks on it move together to clamp the workpiece. Once the transmission assembly in the chuck is damaged, the entire fixture cannot perform the clamping operation, and the clamping blocks that move together to clamp cannot clamp some irregular workpieces, resulting in a small overall range of use and the problem of partial damage and the inability to clamp the entire workpiece.
