Background

At present, hardware parts are commonly used in life, such as hardware connectors, decoration panels, building equipment and the like, and when the hardware parts are produced in an industrialized mass mode, the produced hardware parts are usually required to be cut by using a laser cutting machine.

The existing laser cutting machine generally comprises a laser generator, a beam transmission component, a laser nozzle, a workbench (machine tool), a microcomputer numerical control cabinet, a cooler and the like, when the laser cutting machine is used, the laser generator emits laser, the beam transmission component such as a direction lens converts the direction, the laser is enabled to enter a focusing lens, the focusing lens gathers the light beams and ejects the light beams from the laser nozzle, and hardware components placed on the workbench are cut.

The prior art finds that when a laser cutting machine is used for a period of time, after the position of a focusing lens is adjusted according to the thickness of a hardware part to be cut, the size of a kerf for cutting the hardware part often exceeds a pre-expected range, and after a laser nozzle is replaced, the position of the focusing lens needs to be adjusted again to enable the kerf position of the sprayed laser beam to be cut within a reasonable expected range.

In view of the above problems, through researches of the present inventors, it is found that when a laser beam is transmitted, the laser beam is emitted from an end portion of a laser nozzle, and the laser beam is transmitted near an edge of an object to generate diffraction, so that part of energy of the laser beam acts on the laser nozzle, and therefore after a period of use, the laser nozzle is deformed, and after the laser nozzle is deformed, the laser beam emitted from the laser nozzle cannot be predicted as expected, and the shape and the size of a formed kerf are beyond expectations, because the laser nozzle needs to be replaced; secondly, the existing laser nozzle is usually connected to the beam transmission assembly through threads, but because the threads of the beam transmission assembly and the threads of the laser nozzle usually have machining errors, even if the laser nozzle is sometimes connected to the beam transmission assembly through threads, the laser nozzle is not uniformly applied by manual installation screwing because of the machining errors of the threads, so that after the laser nozzle is installed on the beam transmission assembly, a central axis is not collinear, the beam shape and the energy of a laser beam emitted by the laser nozzle are influenced, and a laser cutting machine is not arranged as expected according to a preset slit cut by the beam formed by the emission of laser emission power corresponding to the thickness of a plate to be cut, so that fine machining cannot be realized.
