Description
Technical field:
The present invention relates to the improvement of fiber adjusting mount structure.
Background technology:
Solid state laser be the laser that will produce in the resonator cavity by coupling device (being fiber adjusting mount), focus on diameter 0.6mm, even in the littler optical fiber, the other end at optical fiber carries out machine work (welding, cladding, processing such as cutting) then.Wherein the quality of coupling mass directly influences the size of output power, thereby influences the performance of laser instrument.
At present, the structure of normally used fiber adjusting mount is a spring formula location structure, or the spherical guide platform structure, and moving forward and backward of slide unit is the effect of leaning on spring.The adjustment of the miniwatt optical fiber such as telecommunication optical fiber below this equipment is mainly used in kilowatt is not suitable for carrying, its poor stability.
Current, the fiber adjusting mount more than still not being applicable to kilowatt; In addition and since kilowatt more than high power, the laser energy density height, the heat that produces when using for a long time is very high, will burn out coupling mirror and optical fiber; This be kilowatt always more than the difficult problem of laser application.
Summary of the invention:
The present invention is exactly at the problems referred to above, provides adjustable flexibly on a kind of space, and stable and reliable operation has the large-power optical fiber adjusting bracket of refrigerating function.
For achieving the above object, the present invention adopts following technical scheme, the present invention includes the coupling mirror support, the mirror cover in its structural feature coupling mirror support outer with the coupling mirror shelf inner diameter for being slidingly matched, mirror is provided with coupling mirror in overlapping; Coupling mirror is the cooling jacket with water inlet pipe, rising pipe between overlapping with mirror; The left of mirror cover is the focal length adjustment lid of coupling mirror; The arm of mirror cover and the arm of coupling mirror support are provided with back-moving spring; The right-hand of coupling mirror support is to adjust frame, pressing plate, adjust in the frame to having the flange of optical fiber, adjust be respectively arranged with on the frame can make flange carry out with respect to the vertical plane of optical fiber about, the adjustment bolt of move left and right, adjust the register pin, the spring that are respectively arranged with on the frame corresponding to the flange of adjusting bolt; Cooling jacket with water inlet pipe, rising pipe is set in the flange.
Beneficial effect of the present invention:
1, adjustable flexibly on the space:
When the present invention needs the conversion focal length, only need rotation focal length adjustment lid, can realize moving axially of coupling mirror, focus on purpose thereby reach the adjustment focal length; Because the effect of back-moving spring power is highly stable after adjusting.
Utilize to adjust bolt can adjust flange carry out with respect to the vertical plane of optical fiber about, the move left and right position, just can easily realize optical fiber about, left and right adjusting, thereby move to the coupling mirror focal position accurately; And, the adjusting of optical fiber is stablized owing to have the effect of the register pin of back-moving spring.
2, have refrigerating function:
Coupling mirror of the present invention and optical fiber are provided with cooling jacket, and the cooling jacket of coupling mirror and optical fiber all adopts the good red copper material of temperature conductivity; Chilled water just can be taken away the heat of coupling mirror and optical fiber absorption by the red copper part of high thermal conductivity, has solved the heating problem of coupling mirror in the superpower laser use, has improved serviceable life; Reduce coupling mirror because the focusing focal shift that thermal deformation causes can be protected optical fiber, can improve laser beam quality again.
