Description
【Technical field】
The utility model is related to a kind of welders, are more particularly to a kind of adjustable laser cutting of optical magnification
System.
【Background technology】
Laser cutting head is varied above existing market, but is broadly divided into two major classes among these, manual focusing cutting
Head and automatic focusing cutting head.The characteristics of manual focusing cutting head, which is laser focus position, to be automatically adjusted, due to plank
Cutting is different with the focal position of laser that plank is perforated, and such manual focusing cutting head punching rate is slow, influences cutting efficiency.From
Dynamic focusing cutting head is not both that focal position is adjustable with manual focusing cutting head maximum, thus can be in cutting and perforated sheet metal
When different focal positions is set, greatly improve plank piercing efficiency, and then improve the cutting efficiency of plank.More than but
Two types cutting head is all there are one common disadvantage, i.e. the collimation focusing of laser cutting head is than non-adjustable, i.e. laser cutting head
Optical magnification be constant.Such design results in cutting head that can only cut the plate being suitble within the scope of its enlargement ratio
Material, such as 100:125 suitable cutting thin plates, 100：200 suitable cutting slabs, 100:150 are suitble to cutting cut deal.Due to client
Cutting plank range is bigger, and from thin plate to slab, existing cutting head cannot meet customer need, therefore, it is necessary to provide one
Kind can with compatible thin heavy-gauge sheeting can the laser cutting system of high efficiency cutting solve the above problems.
【Utility model content】

It realizes that enlargement ratio is adjustable and can automatically adjust the position of focus, solves the problems, such as that optical magnification is nonadjustable.
The utility model is achieved through the following technical solutions above-mentioned purpose：A kind of adjustable laser cutting of optical magnification
System includes laser generator, collimation microscope group successively along optical fiber output direction and focuses microscope group, in the collimation microscope group and
In the focusing microscope group, the focus adjustable of one of them and another focal length is fixed, wherein the collimation microscope group of focus adjustable
Or the focusing microscope group includes the adjustable focus-variable lens of the distance between fixing len and the fixing len and the zoom
The adjustable compensation eyeglass of distance between eyeglass.
Further, the focus-variable lens are realized with the mobile of compensation eyeglass using servo motor or rotary screw.
Compared with prior art, the advantageous effect of the adjustable laser cutting system of a kind of optical magnification of the utility model
It is：The optical magnification for realizing laser cutting head is adjustable so that can be compatible with from thin plate to thickness in laser cutting process
Plate substantially increases the versatility of laser cutting system.Specifically,
1) the collimation microscope group being arranged is the three-piece lens structure that focal length can be changed, and it is continuous in a certain range to realize focal length
Variation；
2) the focusing microscope group of the variable collimating mirror group cooperation fixed focal length of focal length, realizes that optical magnification is variable to swash
Light cutting head；
3) the variable laser cutting head of optical magnification realize from thin plate to slab can high efficiency cutting effect；
4) suitable laser cutting head optical magnification can be found according to plate cutting thickness, and by collimating microscope group
Zoom realize；
5) the compatible cutting from thin plate to slab may be implemented, effectively evaded existing fixed optical magnification cutting head
The shortcomings that being only suitable for cutting respective plates thickness, to which cost is met customer need and reduced to maximum magnitude；
6) laser cutting head optical magnification consecutive variations are realized, best light can be found for different plates thickness
Enlargement ratio is learned, it is more efficient compared to enlargement ratio laser cutting head cutting efficiency is fixed before.
