Description
Technical field
The present invention relates to a kind of reflecting optics cooling device of laser blast wave transmission.
Background technology
In field of laser processing, due to the characteristic of laser blast wave, high power, short pulse can damage optical fiber, it is impossible to pass through
Optical fiber is transmitted, it is therefore necessary to realize the transmission of light path by reflecting optics group or light-conducting arm, and shock wave transmitting procedure again
The middle reflecting optics temperature rise that can cause in reflecting optics group or light-conducting arm so that reflecting optics deformation causes light path to offset,
Influence 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.
When cooling down reflecting optics for existing reflecting optics cooling device, it is impossible to eliminate the thermograde on reflecting optics,
Cause to influence to also reduce the deficiency of the working life of reflecting optics while reflecting optics service precision, need to design one kind can
The device of uniform cooling reflecting optics.
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 laser blast wave transmit reflecting optics
Cooling device.
The purpose of the present invention is achieved through the following technical solutions：
The reflecting optics cooling device of laser blast wave transmission, it is characterised in that：Including：
Bottom plate for placing reflecting optics, provided with the concave station for installing reflecting optics；
Pressing plate is provided with the boss and cooling chamber for being used for compressing reflecting optics, and is provided with the air inlet being connected with cooling chamber
And gas outlet；
The valve inputted for cooling gas is connected at the air inlet, is connected with cooling chamber；
Reflecting optics and thermally conductive sheet are placed between the concave station of bottom plate and the boss of pressing plate；
The pressing plate is mutually locked with bottom plate.
Further, the reflecting optics cooling device of above-mentioned laser blast wave transmission, wherein, on the pressing plate and bottom plate
Screwed hole is equipped with, pressing plate is mutually compressed with bottom plate by screw.
Further, the reflecting optics cooling device of above-mentioned laser blast wave transmission, wherein, the valve passes through pipe spiral shell
Line connected mode is rotatably connected at air inlet.
The present invention has significant advantage and beneficial effect compared with prior art, embodies in the following areas：
The present invention, which is devised, can uniformly cool down the device of reflecting optics, reflecting optics be carried out by cooling gas cold
But, and due to the effect of thermally conductive sheet, the heat of reflecting optics is imported into boss by thermally conductive sheet and cooled down, is effectively reduced
The temperature of reflecting optics, and can effectively eliminate the thermograde on reflecting optics, it is to avoid reflecting optics are because of temperature
It is too high and be deformed, improve the service precision and working life of reflecting optics.

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 and Figure 2, the reflecting optics cooling device of laser blast wave transmission, including：
Bottom plate 1 for placing reflecting optics, provided with the concave station 5 for installing reflecting optics；
Pressing plate 12 is provided with the boss 8 and cooling chamber 4 for being used for compressing reflecting optics, and is provided with what is be connected with cooling chamber 4
Air inlet 10 and gas outlet 9；
The valve 11 inputted for cooling gas is connected at air inlet 10 by pipe screw thread connected mode, with cooling chamber 4
It is connected；
Reflecting optics 2 and thermally conductive sheet 3 are placed between the concave station 5 of bottom plate 1 and the boss 8 of pressing plate 12；
The pressing plate 12 is mutually locked with bottom plate 1.
Pressing plate 12 makes pressing plate 12 mutually be compressed with bottom plate 1 with being equipped with screwed hole on bottom plate 1 by screw 13.
Reflecting optics 2 are cooled down by cooling gas, and due to the effect of thermally conductive sheet 3, by the heat of reflecting optics 2
Amount imports boss by thermally conductive sheet 3 and cooled down, and effectively reduces the temperature of reflecting optics 2, and can effectively eliminate
Thermograde on reflecting optics 2, it is to avoid reflecting optics are deformed because temperature is too high, improve the use of reflecting optics
