Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled plasma cutting machines, in particular to a numerically controlled plasma cutting machine. Background Art

[0002] CNC plasma cutting machine refers to the workpiece instructions (or programs) used to control machine tools or equipment. It is a new control method given in digital form. When this instruction is provided to the control device of the CNC automatic cutting machine, the cutting machine can automatically cut according to the given program. When cutting, the existing CNC plasma cutting machine usually places the metal sheet directly on the workbench without corresponding fixing measures. When encountering external force, the metal sheet is very likely to move, resulting in position deviation and affecting the cutting accuracy.

[0003] The existing Chinese patent CN220259830U discloses a CNC plasma cutting machine, which sets a rotating structure at the bottom of the supporting horizontal plate to cooperate with the fixed structure, and uses the rotation of the bidirectional threaded rod in the rotating structure to drive the fixed structure sleeved thereon to move. After moving to a suitable position, the fixed structure is rotated to the top of the bidirectional threaded rod, and the fixed block is driven to press down the metal plate by rotating the bolt to achieve fixation and prevent the plate from positional displacement;

[0004] However, after the bidirectional threaded rod in the rotating structure of the above-mentioned CNC plasma cutting machine rotates and drives the fixed structure mounted thereon to move, it is still necessary to rotate the corresponding bolts to make the fixed structure press down the metal plate. This method is more troublesome. After rotating one bolt, the worker still needs to move to the other side of the plate to rotate another bolt. The operation is more troublesome and the workload of the workers is large. Utility Model Content

[0005] The purpose of the utility model is to provide a numerically controlled plasma cutting machine to solve the problems raised in the above-mentioned background technology.

[0015] Compared with the prior art, the beneficial effects of the utility model are:
