Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, and more specifically, to a multi-axis moving structure for laser cutting machines. Background Art

[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a slit is eventually formed in the material, thereby achieving the purpose of cutting. Therefore, a multi-axis moving structure is required for the laser cutting machine.

The interior of the moving frame is provided with an annular groove, and a motor is fixedly installed on one side of the moving frame. By providing the protective plate, the sliding groove and the movable rod to cooperate with each other, the mounting plate can be more conveniently protected when moving, so that the collision can be buffered by the spring, reducing the impact force of the mounting plate when colliding, increasing safety and reducing processing costs.

[0004] When using a laser cutting machine with this multi-axis moving structure to laser cut products, when the edge of the product is close to the moving frame, if there is a large lateral distance between the laser cutting head and the cutting part, the laser cutting head cannot be moved laterally (not horizontally along the slide groove) to above the cutting part, resulting in a limited effective cutting range.
