Description
This case has required on 09 25th, the 2012 Chinese utility model patents of submitting to, and application number is 201220492284.7 priority.
Technical field
The utility model relates to a kind of carbon dioxide laser.
Background technology
Carbon dioxide laser can be described as " invisible man ", and the microwave light length that it sends is 10.6 microns, and " body " locates infrared region, and naked eyes can not be perceiveed, and has obtained using widely in fields such as machinery, military affairs, medical treatment, chemical industry.At present, the cylinder of carbon dioxide laser commonly used all is straight tube, and during the assembling complete machine, the carbon dioxide laser of same length, different-diameter can only be installed on the laser machine of different size.
In carbon dioxide laser, gases such as the interior storing carbon dioxide of cylinder, the cylinder two ends are installed in carbon dioxide laser in the laser machine as the installation end of carbon dioxide laser, cylinder is also as the installing rack of reflecting optics with the output eyeglass simultaneously, in carbon dioxide laser, when adding high voltage at electrode, produce glow discharge in the discharge tube, via reflecting optics, the resonant cavity that discharge tube and output eyeglass are formed reflects back formation laser beam and penetrates from the output eyeglass, so reflecting optics and output eyeglass need be over against together, but because reflecting optics and output eyeglass are the ends, two ends that is separately positioned on cylinder, when the carbon dioxide laser two ends are installed in the laser machine as installation end, owing to the deadweight of cylinder bends, the reflecting optics and the output eyeglass relative position that are separately positioned on the cylinder two ends also change with the bending of cylinder, reduce the positive alignment accuracy of reflecting optics and output eyeglass, caused laser beam intensity to reduce.
At present, the cylinder of laser all is isodiametric straight tube, in order to increase the bending strength of cylinder, the diameter of the cylinder that under the situation that does not increase cylinder length, increases normally, after adopting this mode, the bending strength of cylinder increases, reflecting optics and output eyeglass have been improved over against neat precision, also increased the gas-storing capacity of carbon dioxide when improving laser beam intensity, and the effective attenuation degree that has guaranteed carbon dioxide in the cylinder descends, make the power output of carbon dioxide laser stable, the life-span is improved significantly and makes laser be largely increased useful life.
But because cylinder is elongated glass tube, whole process of production need be finished manually, and the diameter that increases cylinder will make the workman be difficult to help cylinder when production and processing, makes the producting process difficulty of cylinder strengthen; Simultaneously, because the diameter of cylinder increases, the diameter that is the carbon dioxide laser installation end also increases thereupon, finally cause the size of the mount pad of installation carbon dioxide laser in the laser machine to cooperate again with cylinder behind the increase diameter, so the carbon dioxide laser that increases behind the cylinder diameter is difficult to use at the laser machine of little direct mount pad, produce the laser machine that is complementary with carbon dioxide laser so must redesign, increased cost greatly.
So it is good to need a kind of versatility at present badly, power output is stable, and the high laser of laser beam intensity.
The utility model content
It is poor that the purpose of this utility model is to overcome in the prior art laser versatility, the power output instability, need to redesign the laser machine that matches with carbon dioxide laser of making increase diameter in order to improve laser beam intensity after, thereby the deficiency that causes cost significantly to improve, provide a kind of, versatility is good, and power output is stable, and the laser beam intensity height, and do not need to design the carbon dioxide laser of laser machine with matching.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of carbon dioxide laser, it comprises cylinder, water cooling tube and discharge tube, water cooling tube is set in the outside of discharge tube, cylinder is set in the outside of water cooling tube, the discharge tube two ends are respectively equipped with anode cavity and negative electrode resonant cavity, be respectively arranged with positive electrode and negative electrode in anode cavity and the negative electrode resonant cavity, the water cooling tube two ends are respectively equipped with water inlet pipe and outlet pipe, anode cavity is connected by the muffler and the cylinder that are coiled in the water cooling tube outside, the middle part of cylinder is provided with lug boss, and the external diameter of lug boss is greater than the external diameter at cylinder two ends.
