Description
Technical field
The present invention relates to a kind of laser reflection eyeglass group transmitting device, more particularly to a kind of speculum for Laser Transmission
The cooling device of piece.
Background technology
In field of laser processing, due to the high power characteristic of laser, reflecting optics temperature can be made during Laser Transmission
Rise so that reflecting optics deformation causes light path to offset, and influences machining accuracy.
The cooling device used at present, inside has coolant storage to receive chamber, and is received in coolant storage and be provided with coolant on chamber
Import and cooling liquid outlet.When in use, cooling device is adjacent to output reflection eyeglass and reflecting optics, and coolant is entered from coolant
Mouth enters coolant storage and receives chamber then from cooling liquid outlet outflow, and reflecting optics purpose is cooled down so as to realize.And use cooling liquid
Cooled down, it is very high to its sealing requirements, once coolant leakage can make reflecting optics surface blur influence optic path, gas
The mode of body cooling there will not be such case.And traditional cooling device is that entirety is fitted on reflecting optics, to reflection
Eyeglass carries out overall cooling, although the temperature of reflecting optics is reduced, but in still showing on reflecting optics
Portion's temperature is of a relatively high, and the relatively low thermograde of peripheral temperature, and this thermograde is appeared on reflecting optics so that
Expansion amplitude in the middle part of reflecting optics is more than the expansion amplitude of periphery, is also reduced while influence reflecting optics service precision anti-
Penetrate the working life of eyeglass.
The content of the invention
The purpose of the present invention be overcome the shortcomings of prior art exist there is provided a kind of reflecting optics for Laser Transmission
Cooling device.
The purpose of the present invention is achieved through the following technical solutions：
For the cooling device of the reflecting optics of Laser Transmission, feature is：Including：
Microscope base for placing reflecting optics, is connected with base；
The reflecting optics reflected for light path and the thermally conductive sheet for increasing radiating effect, pass through eyeglass pressing plate and microscope base
Connection；
For being connected to the cooling lid that reflecting optics are cooled down with base；
The cooling lid has cooling chamber, which is provided with air inlet and gas outlet；Connect for the valve that cooling gas is inputted
It is connected on air inlet.
Further, the cooling device of the above-mentioned reflecting optics for Laser Transmission, wherein, the microscope base passes through fixation
Screw is fixedly connected with base.
Further, the cooling device of the above-mentioned reflecting optics for Laser Transmission, wherein, the cooling lid and base
Between be provided with diaphragm seal.
Further, the cooling device of the above-mentioned reflecting optics for Laser Transmission, wherein, the eyeglass pressing plate and mirror
It is fixedly connected between seat by screw.
The present invention has significant advantage and beneficial effect compared with prior art, embodies in the following areas：
1. the present invention is cooled down by cooling gas to reflecting optics, and due to the effect of thermally conductive sheet, by speculum
The heat of piece imports cooling lid by thermally conductive sheet and cooled down, and effectively reduces the temperature of reflecting optics, and can be effective
The thermograde eliminated on reflecting optics, it is to avoid reflecting optics are deformed because temperature is too high, improve reflecting optics
Service precision and working life；
2. reflecting optics can uniformly be cooled down, it is to avoid occur higher thermograde on reflecting optics, so as to improve reflection
The reflecting optics cooling device of eyeglass service precision and working life, and use card insert type eyeglass mounting means so that eyeglass
Installation with dismounting more facilitate.
Brief description of the drawings
Fig. 1：The structural representation of the present invention.
Embodiment
In order to which technical characteristic, purpose and effect to the present invention are more clearly understood from, specific implementation is now described in detail
Scheme.
As shown in figure 1, the microscope base 14 for placing reflecting optics 2, is fixedly connected by fixing screws 1 with base 13；
The reflecting optics 2 and thermally conductive sheet 3 for increasing radiating effect reflected for light path, by eyeglass pressing plate 4 with
Housing screw 5 is fixedly connected with microscope base 14；
Pass through screw 7 and base 13 for the cooling lid 6 cooled down to reflecting optics 2 and for the sealing 12 of sealing gas
It is fixedly connected；
Cooling lid 6 has cooling chamber 11, which is provided with air inlet 9 and gas outlet 10；The valve 8 inputted for cooling gas
It is connected on air inlet 9.
During concrete application, reflecting optics 2 are cooled down by cooling gas, and due to the effect of thermally conductive sheet 3, will be anti-
The heat for penetrating eyeglass 2 is cooled down by the importing of thermally conductive sheet 3 cooling lid 6, effectively reduces the temperature of reflecting optics 2, and
The thermograde on reflecting optics 2 can be effectively eliminated, it is to avoid reflecting optics 2 are deformed because temperature is too high, improved
The service precision and working life of reflecting optics 2, and use card insert type eyeglass mounting means so that the installation of eyeglass is with tearing open
Unload and more facilitate.
In summary, when the present invention cools down reflecting optics for existing reflecting optics cooling device, it is impossible to eliminate speculum
Thermograde on piece, causes to also reduce the working life of reflecting optics not while influence reflecting optics service precision
Foot can uniformly cool down reflecting optics there is provided one kind, it is to avoid occur higher thermograde on reflecting optics, so as to improve anti-
Eyeglass service precision and the reflecting optics cooling device of working life are penetrated, and uses card insert type eyeglass mounting means so that mirror
The installation of piece more facilitates with dismounting.
It should be noted that：The preferred embodiment of the present invention is the foregoing is only, the power of the present invention is not limited to
Sharp scope；Simultaneously more than description, should can understand and implement for the special personage of correlative technology field, thus it is other without departing from
The equivalent change or modification completed under disclosed spirit, should be included in claim.
