Laser cutting machine with automatic positioning function

Abstract

The invention discloses a laser cutting machine with an automatic positioning function. The laser cutting machine with an automatic positioning function structurally comprises a sealing cover, a cutting device, a crushed aggregate outlet and an air supply outlet; the cutting device is provided with a movable frame, a fixing structure, a rotating mechanism, a telescopic device and a laser cutter; abent plate on the outer side of a compression structure slides on the outer side of a spring, so that a telescopic rod is kept in a vertical state, excessive vibration force is avoided, the light andheavy deviation phenomenon of a machined material is prevented, the cutting precision is prevented from being reduced, and the broken position cutting phenomenon is prevented; a rubber hole acts on the machined material by controlling retracting and releasing of the telescopic rod; two-point fixing is conducted through stretching and retracting of the telescopic rod, so that infirm fixing is avoided, and the breaking phenomenon of the machined material is prevented; and meanwhile, due to the characteristic that the compression block is stressed to deform, the attaching force to the machined material is enhanced, so that the machined material is clamped, and the laser cutting device adapts to the machined materials with various shapes; and the laser cutting device cuts the other side of the machined material by using the rotating plate to rotate the machined material, so that cutting of the thicker machined material is enhanced.

Description

technical field [0001] The invention relates to the field of laser cutting, in particular to a laser cutting machine with automatic positioning function. Background technique [0002] Laser cutting is realized by applying high power density energy generated by laser focusing.

[0002] Laser cutting is realized by applying high power density energy generated by laser focusing. The laser is discharged through pulses, and the processing material is melted or vaporized at high temperature at the moment of discharge, and a small hole is sputtered on the surface. The laser processing head and the workpiece are The processed materials are dotted with continuous relative motion according to the pre-drawn graphics to form the desired graphics. However, during the cutting process of the cuboid aluminum alloy material, the laser is affected by the wavelength of the solid-state laser, and the formed rays are prone to fading, resulting in processed The thickness of the material is limited within a certain range, and it is not easy to cut thicker processed materials, and when the processed material is fixedly turned over for the second cutting, the aluminum alloy material is slightly inclined due to the influence of gravity and toughness, so that the aluminum alloy material The horizontal position of the horizontal position deviates, causing the offset between the second cutting position and the first cutting position, resulting in a decrease in cutting accuracy
