Description
Technical field
The present invention relates to a kind of laser cutting head leaded light focusing system, belong to field of mechanical technique.
Background technology
Laser cutting machine is the laser that will launch from laser, through light path system, is focused into the laser of high power density
Beam.Laser beam is irradiated to workpiece surface, workpiece is reached fusing point or boiling point, at the same the gases at high pressure coaxial with light beam will melt or
Gasified metal is blown away.With the movement of light beam and workpiece relative position, material is finally set to form joint-cutting, so as to reach the mesh of cutting
's.
Laser cutting is that traditional mechanical blades are instead of with sightless light beam, has precision high, cutting is quick, no
It is confined to cut pattern limitation, Automatic Typesetting saves material, the features such as otch is smooth, and processing cost is low, gradually will improve or take
In generation, is in traditional metal cutting processes equipment.The mechanical part of laser probe and workpiece are contactless, at work will not be to workpiece
Cause to scratch in surface；Laser cutting speed is fast, and smooth cut is smooth, typically without following process；It is small to cut heat affected area, sheet material
Deform small, joint-cutting is narrow（0.1mm-0.3mm）；Otch does not have mechanical stress, no shear burr；Machining accuracy is high, reproducible, no
Attacking material surface；Numerical control programming, arbitrary plan can be processed, the cutting of whole plate that can be very big to breadth, without mold,
It is economical time saving.
With the development of laser cutting machine, people are to its process velocity and the requirement more and more higher of machining accuracy.
The content of the invention
The purpose of the present invention is overcome the deficiencies in the prior art part, there is provided a kind of laser cutting head focusing system.
The present invention laser cutting head leaded light focusing system, including instruction light-source system, total reflection film horse, laser pump cavity A,
Diaphragm, laser pump cavity B, semi-reflective film horse, beam expander, completely reflecting mirror and focusing system, described focusing system include lens
Seat and focus-regulating device；
Described lens mount includes microscope base, the focusing lens being connected with microscope base, the upper lower gasket and microscope base being connected with focusing lens
Connected handle；
Described focus-regulating device, including rotary sleeve, be located above rotary sleeve sliding sleeve, be connected with sliding sleeve sealing ring, set
Spacer pin, guide sleeve and expansion set on the outside of sliding sleeve.
Compressed air inlet, cooling water inlet, coolant outlet, cutting auxiliary gas are provided with around described focusing lens
Entrance and indium wire ring.
The laser cutting head leaded light focusing system of the present invention, brings process velocity fast to numerical control laser cutter, processing essence
Spend high technological merit.
