The normal incidence of a horizontal laser beam can be implemented toward the spherical focusing mirror through the utility model. In addition, the laser beam after focusing can completely pass through the through hole and the nozzle, avoiding the focal aberration of the oblique incidence of the spherical mirror. The utility model has the advantages of convenient replacement, low cost, simple change of the focal length, improved adaptability and interchangeability of the full reflection focusing device, etc.
Description
The invention belongs to outer light path laser-processing system.
In the prior art, the focalizer that the industrial lasers system of processing is used generally is divided into two kinds of forms; Be transmission-type focalizer and reflective focalizer.The transmission-type focalizer mainly is made of be all-trans speculum and crystalline lens.Because crystalline material itself destroys the restriction of threshold values, in laser power during greater than 3KW, crystalline lens easily produce burst breakoff phenomenon, particularly crystalline lens itself thermal lensing effect to Laser Processing, as punching, the quality of welding, cutting has very big influence.Therefore, for the system of processing of laser power, mainly adopt reflective focusing at present both at home and abroad in the commercial production greater than 3KW.
The external at present reflective focalizer that generally adopts mainly is made of level crossing and aspheric mirror.But because the aspheric mirror difficulty of processing is big, the process-cycle is long, costs an arm and a leg, and brings great difficulty for practical application, particularly focusing transform.
The purpose of this utility model is that adopting process maturation, the common spherical mirror that interchangeability is good replace aspheric mirror, reduces the reflect focalization installation cost, improves reliability, the adaptability of reflect focalization device in commercial production.Be at present domestic and international high power CO
2The laser-processing system of the unsteady cavity ring-shaped light spot output that laser instrument extensively adopts find a kind of technical maturity, with low cost, change convenient, the minimum normal incidence of the aberration spherical surface focusing device that is all-trans.
The said normal incidence of the utility model is all-trans the spherical mirror focalizer by optical bench, plane mirror, spherical surface focusing mirror, compositions such as regulating system and blow-out nozzle.On optical bench (1), the direction of injecting towards annular laser beams be mounted with one can angle at 45 plane mirror (2), a through hole (3) that focused light is passed through is arranged in the centre of plane mirror (2); On the optical bench (1) of the top of plane mirror (2), there is a spherical surface focusing mirror (4) to be placed in the mirror holder (5), fixing by gland (6); On the optical bench (1) of the below of plane mirror (2), be mounted with laser nozzle (7).The through hole (3) and the laser nozzle (7) of said spherical surface focusing mirror (4), plane mirror (2) should be on same straight lines.
Advantage of the present utility model and effect are: the characteristics of utilizing the no laser energy of ring in the ring-shaped light spot, the narrow meshed 45 plane mirror in the center of designing, these 45 ° of plane mirrors can be with the laser beam vertical reflection to the focus lamp surface, and the laser beam after the line focus is acted on the surface of the work by aperture.Because laser beam is vertical with the focusing minute surface, the aberration of focus when having avoided the spherical mirror oblique incidence, changed and had the situation that the reflect focalization system must adopt aspheric mirror both at home and abroad now, make the replacing or the focal length of focus lamp change simple, reduced the cost of reflect focalization device, improved the adaptability and the interchangeability of total reflection focalizer, helped suitability for industrialized production and use.
Steel plate test sample through utilizing focalizer described in the utility model to weld shows that compared with prior art, welding seam deep width ratio is big, and even weld is counter-bending, and tensile strength is good.

Accompanying drawing 2: the normal incidence spherical mirror focalizer light path synoptic diagram that is all-trans;
Accompanying drawing 3: the normal incidence another kind of light path synoptic diagram of spherical mirror focalizer that is all-trans.
Below in conjunction with drawings and Examples the said focalizer of the utility model is further described.
45 ° of plane mirrors (2) are fixed on the optical bench (1), on plane mirror (2) flanged plate (8), have the waist shape sliding tray (10) of settling gib screw (9), can make 45 ° of plane mirrors (2) certain surplus of rotating be arranged relative to optical bench (1), to keep the through hole (3) in 45 ° of plane mirrors (2) coaxial with spherical surface focusing mirror (4) center line all the time, purpose is to make the whole reflected in parallel of loop laser beam energy to spherical surface focusing mirror (4), and laser beam energy again can be all by through hole (3) after the line focus.Bosh (11) and turnover water nozzle (12) are arranged on 45 ° of plane mirrors (2) seat.
Spherical surface focusing mirror (4) be placed in corresponding optical bench (1) position of 45 ° of plane mirrors (2) on.Spherical surface focusing mirror (4) is placed in the mirror holder (5), and is fixing by gland (6), is provided with cooling water channel (13) and Inlet and outlet water spray (12) between spherical surface focusing mirror (4) and gland (6).There is the set screw (14) more than three or three to be attached on the mirror holder (5).
Laser nozzle (7) is placed on the optical bench (1) on the same linear position of through hole (3) with spherical surface focusing mirror (4), 45 ° of plane mirrors (2).Air admission hole (16) is arranged having on the periphery in laser nozzle (7) hole on the annular blowing groove (15); can be by the control of blow gas pressure and flow; reach and dispel plasma around the workpiece, prevent the purpose that surface of the work oxidation and protection optical element are avoided polluting.Cooling water channel (17) also can be set on laser nozzle (7).
The be all-trans light path synoptic diagram of spherical mirror focalizer of the normal incidence of utilizing the said focalizer of the utility model and constituting the different structure form that is respectively accompanying drawing 2 and accompanying drawing 3.
