Abstract
The invention relates to the field of lasers, in particular to a carbon dioxide laser with a planar-disc-shaped elastic supporting frame. The carbon dioxide laser with the planar-disc-shaped elastic supporting frame comprises an air storage pipe, a water cooling pipe and a discharge pipe which are arranged sequentially in a sleeved mode from outside to inside. The water cooling pipe is fixedly connected with the discharge pipe. The supporting frame is arranged between the water cooling pipe and the air storage pipe and is fixedly connected with the water cooling pipe and the air storage pipe. The supporting frame has elasticity in the length direction and the radial direction of the air storage pipe. Because the supporting frame is fixedly arranged between the water cooling pipe and the air storage pipe and has elasticity in both the length direction and the radial direction of the air storage pipe, when the laser is impacted in the length direction or the radial direction, the supporting frame can provide elastic deformation of a certain degree and has a buffer effect, and internal structures of the laser are prevented from cracking when the laser is impacted.
Description
Technical field
The present invention relates to field of lasers, particularly a kind of carbon dioxide laser with plane plate-like flexible supporting frames.
Background technology
Because carbon dioxide laser has larger power and higher energy conversion efficiency, spectral line is also abundanter, has the Laser output of tens spectral lines near 10 microns, is all widely used at aspects such as industry, military affairs, medical treatment, scientific researches.
Current carbon dioxide laser, generally include discharge tube, be set in the water cooling tube of discharge tube outside, be set in water cooling tube outside cylinder, be arranged on the electrode at discharge tube two ends and be arranged on cylinder two ends output window and reflection window, reflection window includes reflecting optics and reflecting optics cooling device, output window includes output eyeglass and output eyeglass cooling device, fills with carbon dioxide and other assist gas in discharge tube; When add high voltage on electrode time, in discharge tube, produce glow discharge, after reflecting optics and output lens reflecting, form laser beam, from output eyeglass, penetrate and obtain final laser beam.
Because laser is generally slim-lined construction, discharge tube is set in water cooling tube, and water cooling tube is set in cylinder, ensures the fixing of relative position between water cooling tube and cylinder needing to arrange bracing frame between water cooling tube and cylinder.
Due to the special architectural characteristic requirement of laser, need bracing frame to be different from conventional bracing frame, and possess the ability of many aspects simultaneously.
First, because cylinder, water cooling tube and the discharge tube of laser are all glass workpiece, its poor plasticity, shock-resistant ability, so need bracing frame when the support force of vertical direction is provided, also need bracing frame to there is certain elasticity at vertical direction, make laser in being subject to vertical direction impact, bracing frame can provide elastic deformation amount to a certain degree, and each slender rectangular tube of avoiding laser inside destroys because of the impact of vertical direction;
Secondly,, in the time that laser is moved transport, usually also can be subject to impulsive force along its length, so also need bracing frame can provide along the support force of laser length direction; But, in the time of laser works, the temperature of discharge tube and water cooling tube raises gradually, make the length of discharge tube and water cooling tube also can there is the elongation of certain length, so make bracing frame providing along in the support force of laser length direction, also need on the length direction along laser, there is certain elasticity, to play cushioning effect, avoid each slender rectangular tube of laser inside because destroying along the impact of laser length direction;
For this reason, inventor through with great concentration research and development and some tests after, designed a kind of plate-like bracing frame, refer to Chinese patent, the patent No.: CN203585734U, denomination of invention is " a kind of plate-like bracing frame ", has more perfectly solved the problems referred to above by this plate-like bracing frame.
But, along with inventor further furthers investigate, and the problem feeding back with client in actual production, inventor's discovery, the plate-like bracing frame of above-mentioned this structure still exists deficiency.Be embodied as, in the insufficient strength along laser length direction, in the time that laser is subject to impact along its length, bracing frame fracture easily occur, or be connected disconnection between bracing frame and cylinder or water cooling tube, cause laser inside cracked; And along cylinder footpath upwards be rigid support substantially, so in the time that laser is subject to impacting, can not be along enough distortion buffering capacities are provided in cylinder direction radially.All these reasons cause laser moving in transportation, as easy as rolling off a log impact and damaging, and the proportion of goods damageds are high, directly restricted the popularization of product.
So, need at present the reliable carbon dioxide laser connecting between a kind of internal water cooling pipe and cylinder badly.
Summary of the invention
The object of the invention is to: for existing carbon dioxide laser above shortcomings, provide the reliable carbon dioxide laser connecting between a kind of internal water cooling pipe and cylinder.
