Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of laser cutting machines, in particular to an adjustable cutting head of a laser cutting machine. 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 is irradiated onto the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. 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. Laser cutting processing has the characteristics of high precision, fast cutting, no limitation on cutting pattern, automatic typesetting to save materials, smooth incision, and low processing cost.
[0003] When using a laser cutting machine, the workpiece to be processed is generally placed on the workbench, and the laser cutting head is driven downward by the adjustment component. After it moves to the appropriate position, the laser cutting head is used to cut the workpiece. However, in the process of the laser cutting head being driven downward by the adjustment component, the laser cutting head is prone to collision with the workpiece, and when the laser cutting machine is idle, the laser cutting head is generally still exposed to the outside world. When the laser cutting machine is collided, it is easy to cause damage to the laser cutting head, thereby affecting the normal use of the laser cutting machine. Utility Model Content

[0013] (1) The utility model adds a protective plate to the outside of the laser cutting head, and installs a first connecting block and a rotating plate on the protective plate. When the electric telescopic rod is started to work, the rotating plate rotates in the first connecting block, and the angle between the electric telescopic rod and the rotating plate changes, so that the rotating plate pulls the protective plate to rotate on the surface of the rotating shaft.
