Laser cutting device

Abstract

The invention discloses a laser cutting device which comprises a laser head, a moving module and a clamp, wherein the clamp is provided with a positioning part used for positioning a pipe fitting, the clamp is provided with a reference device matched with the positioning part, the reference device is used for the laser head to accurately find the initial cutting position, and the positioning part is connected with the reference device through a transmission part. The laser cutting device is characterized in that a waste receiving device capable of storing cut waste is arranged in the positioning part, and a driving part which is matched with the moving module and can drive the reference device and the waste receiving device to move is arranged on the clamp. The invention provides the laser cutting device which accurately finds a cutting reference point during turnover cutting; and after cutting, waste is directly collected and cannot adhere to the inner wall of the pipe fitting, so that the cutting quality is improved while the cutting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of laser cutting equipment, in particular to a laser cutting device. Background technique [0002] The laser cutting machine focuses the laser light emitted from the laser device into a high power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal; the existing laser cutting machine is usually used to cut the plate. [0003] However, in production and manufacturing, it is usually necessary to open through holes on pipe fittings such as square pipes, rectangular pipes, etc. Some holes are non-standard round holes, which need to be processed by laser cutting. One side is processed, and then the other side is processed after turning the pipe 180°. At this time, the center of the through ...

[0003] However, in production and manufacturing, it is usually necessary to open through holes on pipe fittings such as square pipes, rectangular pipes, etc. Some holes are non-standard round holes, which need to be processed by laser cutting. Process one side, then turn the pipe 180° and process the other side. At this time, the center of the through hole processed will be deviated due to the inaccurate positioning of the processing reference, which will affect the subsequent installation; and the slag will fall when processing the first side Adhesion formed on the inner wall of the tube is difficult to remove and affects the processing of the second surface
