Description
Technical field
The present invention relates to field of lasers, more particularly to a kind of carbon dioxide laser with discotic flexible supporting frames
Device.
Background technology
Because carbon dioxide laser has bigger power and higher energy conversion efficiency, spectral line is also richer
Richness, nearby there is the laser output of tens spectral lines at 10 microns, be obtained for extensively in industry, military, medical treatment, scientific research etc.
Application.
Current carbon dioxide laser, discharge tube, the water cooling tube being set in outside discharge tube are generally included, is set in
Cylinder outside water cooling tube, the output window for being arranged on the electrode at discharge tube both ends and being arranged on cylinder both ends and reflection
Window, reflection window include reflecting optics and reflecting optics cooling device, and output window includes output optic acts and output optic acts cooling
Device, carbon dioxide and other auxiliary gases are filled with discharge tube；When in high voltage on electrode, produced in discharge tube
Raw glow discharge, laser beam is formed after reflecting optics and output optic acts reflection, projected from output optic acts and obtain final swashing
Light beam.
Due to the generally elongated structure of laser, discharge tube is set in water cooling tube, and water cooling tube is set in cylinder
It is interior, need to set support frame to ensure the fixation of relative position between water cooling tube and cylinder between water cooling tube and cylinder.
Because the special architectural characteristic requirement of laser is, it is necessary to which support frame is different from conventional support frame, and is provided simultaneously with
The ability of many aspects.
Firstly, since the cylinder of laser, water cooling tube and discharge tube are all glass workpiece, and its poor plasticity, impact resistance energy
Power is poor, so needing support frame while the support force of vertical direction is provided, it is also necessary to which support frame has one in vertical direction
Fixed elasticity, making laser, support frame can provide a certain degree of elastic deformation amount when being impacted by vertical direction,
Each slender rectangular tube inside laser is avoided to be destroyed because of the impact of vertical direction；
Secondly, usually also can be by impulsive force along its length, so also needing to support when laser moves transport
Frame can provide the support force along laser lengths direction；However, in laser works, the temperature of discharge tube and water cooling tube by
Edge up height so that the length of discharge tube and water cooling tube can also have the elongation of certain length, so that support frame is providing
Along laser lengths direction support force while, it is also necessary to there is certain elasticity on the length direction along laser, with
Cushioning effect is played, avoids each slender rectangular tube inside laser from being destroyed because of the impact along laser lengths direction；
Therefore, if inventor have devised a kind of disk shaped support frame, refer to Chinese special through researching and developing with great concentration with after dry test
Profit, the patent No.：CN203585734U, it is entitled《A kind of disk shaped support frame》, it is more perfect by this disk shaped support frame
Solve above mentioned problem.
But as inventor further furthers investigate, and in actual production and asking of being fed back of client
Topic, inventor have found that still there is deficiency for the disk shaped support frame of above-mentioned this structure.It is embodied as, is grown along laser
The insufficient strength in direction is spent, when laser is by impact along its length, support frame fracture, or support frame easily occurs
Connection between cylinder or water cooling tube disconnects, and causes fragmentation inside laser；And in the base along cylinder radially
This is rigid support, so when laser is impacted, it is impossible to provide enough changes on the direction along cylinder radial direction
Shape buffering capacity.All these reasons cause laser in transportation is moved, and are easy to be impacted and damaged, proportion of goods damageds pole
Height, directly constrain the popularization of product.
So need the carbon dioxide laser being reliably connected between a kind of internal water cooling pipe and cylinder badly at present.
The content of the invention
It is an object of the invention to：For existing carbon dioxide laser above shortcomings, there is provided a kind of internal
The carbon dioxide laser being reliably connected between water cooling tube and cylinder.
