Description
Technical field
The present invention relates to a kind of laser process equipment, specifically a kind of laser tube that is used on the laser engraving machine.
Background technology
Glass enclosed type CO
2Laser is formed by the glass tube encapsulation, so be commonly called as laser tube.Laser tube can be used for carving or cutting on the laser engraving machine of nonmetallic materials such as rubber, plastics, textile.
The operation principle of laser tube is: electrion excites high concentration CO
2Gas produces the laser of wavelength 10.6um, and it mainly contains hard glass, resonant cavity, electrode three parts composition:
1, hard glass part: these parts are fired into discharge tube, water collar, gas storage cover and muffler by GG17 and form.Enclosed type CO
2Laser is generally three layers of sleeve structure.Innermost is discharge tube, and the centre is that water overlaps only, and outermost one deck is the gas storage cover, and muffler is to be used to be communicated with discharge tube and gas storage cover.
2, resonant cavity part: these parts are made up of total reflective mirror and output reflector.The total reflective mirror of resonant cavity generally is substrate with optical glass, the surface gold-plating film, and golden film speculum reaches more than 98% near the reflectivity the 10.6um; The germanium (Ge) that the output reflector of resonant cavity generally adopts transmissive 10.6um radiation is substrate, plates multilayer dielectric film in the above and makes.
3, electrode part: CO
2Laser generally adopts cold cathode, is shaped as cylindrical shape, and cathode material selects for use the life-span to laser to have a significant impact, and the basic demand of target material is: sputtering raste is low, and the bulk absorption rate is little.
The life-span of laser tube differs bigger at present, mainly is that factors such as designing technique cause owing to processing technology.The working life of general homemade laser tube is (60W is an example) about 1500 hours.The laser tube of different performance, largest light intensity there are differences, i.e. the laser energy difference.Optical quality is by laser tube pattern decision, the quality of hot spot, and by all too many levels decisions of production technology, the performance that the quality of hot spot directly has influence on the user when using.The stable difference of different laser tubes is also very big, the product of poor performance, and stable aspect is prone to gas leakage, and non-external cause such as bursts at problem.
The structure of existing laser tube is seen Fig. 1, and it mainly is in the hard glass body 11 of a sealing, fills out and is provided with carbonated mist, and the set electrode 12 at the laser tube two ends forms a resonant cavity and then produces laser.End at body 11 is provided with the laser head 13 that has eyeglass 14.Because laser head and the hard glass body that uses is linked to be an integral body at present, eyeglass is fixed in the laser head, and the material of laser head is the glass consistent with the hard glass body, producing laser simultaneously, horminess glass tube is known from experience the heating distortion, causes laser head heating distortion, causes laser head to damage and can not use, and then make and whole laser tube subscription rate increased cost.
Summary of the invention
In order to overcome the problem that prior art exists, the purpose of this invention is to provide a kind of laser tube, the laser head in this laser tube is replaceable, and is durable in use, and long service life has been saved user's cost greatly; And power is big, penetration power is strong.
The objective of the invention is to be achieved through the following technical solutions:
A kind of laser tube is provided with the laser resonator of connection on body; End in laser resonator is provided with laser head, it is characterized in that: the described laser head that is made of metal comprises Connection Block and lens permanent seat, is provided with the endoporus suitable with body on Connection Block; Between lens permanent seat and Connection Block, be provided with eyeglass; Connection Block is connected with lens permanent seat by screw, and is provided with the adjustment screw between Connection Block and lens permanent seat.
The present invention is provided with discharge aperture on lens permanent seat.In order to prevent that electric discharge phenomena take place when producing laser, on lens permanent seat, be provided with discharge aperture.
Because laser tube is the easy consumption parts, existing glass laser pipe is generally as disposable use.And be made of metal owing to laser head among the present invention, be connected on the canals of stilling by glue, indeformable when canals of stilling adstante febre laser head, therefore can inflate use repeatedly.Compared with prior art, laser head of the present invention is replaceable, and is durable in use, and long service life has been saved user's cost greatly; And power is big, penetration power is strong, cheap, economical and practical, has obtained domestic and international client's approval.

Embodiment
A kind of laser tube of the present invention is provided with the laser resonator of connection on body; End in laser resonator is provided with laser head 3.The laser head 3 that is made of metal comprises Connection Block 31 and lens permanent seat 32, and laser head 3 can be made of copper.On Connection Block 31, be provided with the endoporus 311 suitable with body; Connection Block 31 is removably disposed on the body by endoporus 311.Between lens permanent seat 32 and Connection Block 31, be provided with eyeglass 33.Eyeglass 33 is fixed between lens permanent seat 32 and the Connection Block 31.Connection Block 31 is connected with lens permanent seat 32 by screw, and is provided with adjustment screw 4 between Connection Block 31 and lens permanent seat 32.Adjust screw 4 and be used for regulating the focal length of eyeglass 33 to guarantee laser effect.
In order to prevent that electric discharge phenomena take place when producing laser, on lens permanent seat 32, be provided with discharge aperture 5.
During use, laser head 3 is installed on the body.Because laser head is made of metal, be connected on the canals of stilling by glue, indeformable when canals of stilling adstante febre laser head, therefore can use repeatedly.When eyeglass can not meet the demands, just change laser head, as long as laser head is taken off, load onto new laser head again and can continue to use.The present invention is durable in use, and long service life has been saved user's cost greatly; And power is big, penetration power is strong, cheap, economical and practical, has obtained domestic and international client's approval.
