Annular laser cutting machine and using method

Abstract

Provided is an annular laser cutting machine. The machine comprises a fixing frame, a clamping assembly, a fixing base, a cutting barrel, and an optical fiber wire spool. The optical fiber wire spoolis fixed above the fixing frame; the cutting barrel is arranged above the optical fiber wire spool; the fixing base is arranged inside the cutting barrel and used for clamping and fixing a workpiece;and the clamping assembly is arranged beside the fixing frame and used for clamping the workpiece to be placed on or away from the fixing base. A rotating assembly is arranged below the fixing frame,and a through hole for connecting the rotating assembly with the cutting barrel is formed in the middle of the optical fiber wire spool; the rotating assembly is in transmission connection with the cutting barrel; and the rotating assembly rotates to drive the cutting barrel to rotate. When the cutting barrel rotates, the fixing base keeps still, so that the fixing base keeps still during cutting,and the cutting barrel rotates to cut the workpiece, the clamping force on the workpiece cannot be weakened during cutting of the fixing base, and the workpiece is stably cut and the cutting openingof the workpiece is flat can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of laser cutting, in particular to a ring laser cutting machine and a usage method. Background technique [0002] The current cutting machine clamps and fixes the workpiece, and a device for driving rotation is provided under the workpiece, and a laser device is arranged beside the workpiece to cut the workpiece. The rotating device drives the workpiece to rotate itself so that the workpiece is circularly cut by the laser device. However, this cutting method is started by the self-rotation of the workpiece. A large number of sparks will be generated when cutting the workpiece, which will affect the safety of bypass wires or workers, and when the self-rotation, the clamping force of the clamping workpiece is weakened, causing the cutting position of the workpiece to fluctuate up and down, and sometimes the complete cutting cannot be achieved. The plane affects the assembly of the workpiece in the later stage...
