Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machine equipment, and specifically relates to a laser cutting machine with an automatic positioning function. Background Technique

[0002] Laser cutting is achieved by applying the high-power density energy generated after laser focusing. That is, the laser emitted from the laser is focused into a laser beam with a high power density 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 melted or vaporized metal. In the prior art, during the use of a laser cutting machine, the laser cutting position is adjusted by continuously moving the object. If good sliding adjustment is not adopted for the movement of the object, it will cause the object to be worn under the state of large friction for a long time, and the surface is easily damaged, affecting the finished product.

[0003] For example, a laser cutting machine with an automatic positioning function for thick plate carbon steel disclosed in the authorized patent document with the application number 202222343853.8 includes a machine body, a controller, a sliding mechanism, a laser cutting mechanism and a pressing plate. The controller is arranged at the upper right of the machine body, the sliding mechanisms are arranged on the left and right sides of the machine body, a collection box is arranged above the support plate, an air extraction pump is arranged on one side of the collection box, a connecting pipe is connected to one side of the air extraction pump, a support frame is arranged above the machine body, a cylinder is arranged above the support frame, and a pressing plate is arranged below the cylinder. Through the setting of the pressing plate in the utility model, when the thick plate carbon steel is placed on the workbench of the machine body for cutting work, the cylinder can drive the pressing plate to move up and down, so as to press and position the thick plate carbon steel, without manual fixed hand-held positioning, ensuring the stability of the thick plate carbon steel during cutting, and effectively avoiding the phenomenon of position deviation and cutting error of the thick plate carbon steel.

[0004] The above patent also has the problem that the laser cutting position is adjusted by continuously moving the object. If good sliding adjustment is not adopted for the movement of the object, it will cause the object to be worn under the state of large friction for a long time, and the surface is easily damaged, affecting the finished product. Therefore, we need to provide a laser cutting machine with an automatic positioning function. Content of the Utility Model
