At present, known needs are generally directly welded by welding flange compared with the optics cavity of long light-path or bolt is connected and fixed, due to the error that workpiece own or standard component produce in process of production, the collimation of welding or the light path after being connected and fixed easily is caused not meet light path needs; Directly place optical mirror slip (window, high reflective mirror etc.) simultaneously, after tightening one-piece construction, the metal fragment that the meshing process of optic conduit internal and external threads can be made to produce remains in optics cavity interior focusing eyeglass and causes damage, the rubbery flat gasket of simultaneously outside realization sealing pipeline internal and external threads repeatedly meshing process easily produce damage, generally simultaneously the mode of single optical eyeglass dullness joint, cannot according to the needs of optical demands in various degree.
Summary of the invention
Not easily regulate compared with the optics cavity pipeline of long light-path to solve existing part instrument, not easy to clean metal fragment, not easily meet the object of the needs of multiple optical demands, the invention provides a kind of device realizing the adjustment of pipeline beam path alignment for laser on-line gas analysis instrument, this device can not only realize the collimation variable adjustment of whole light path, range of adjustment is larger, two segment pipes that can realize not coenosarc regulate, the metal fragment that simultaneously can produce in the meshing process of double thread is cleared up, avoid the damage to optical mirror slip, and adopt universal pipe connecting structure, achieve the feature shared of many arrangements of mirrors sheet.
The technical solution adopted for the present invention to solve the technical problems is:
1, the bone flange governor motion adopting convex spherical and concave spherical surface to be formed realizes the variable adjustment of beam path alignment degree, realize two panels flange by the adjusting part tightening, unscrew screw gasket, spring is formed to rotate in the X of space perpendicular, Y-direction centered by the centre of sphere of sphere, thus the collimation of adjustment light path.
2, can adaptive sizes, kind optical mirror slip, window adapter can be adopted for common window, optical mirror slip for high reflectances such as high reflective mirrors adopts high reflective mirror adapter, and adopts high precision fine tuning structure to finely tune, can choice for use as required.
3, in order to solve kish fines problem, adopt the two thread connecting mode of pipeline, it is no longer traditional direct meshing connection of internal and external threads, the optics cavity pipeline junction connected again was cleared up in all both needs, adopt external thread, utilize the internal thread of external collar to be locked by two parts, both realizations connect.
4, in light path system, each several part will become a relatively independent optics cavity, and can meet working environment needs and have sealed characteristic that is dust-proof, waterproof, adopts the pipeline thread of convenient disassembly to connect, and realizes respectively the sealing of independently optics cavity with O type circle.
5, the principle of versatility is adopted to increase according to the needs of practical function or to reduce the intensity, collimation etc. that lens number of tubes realizes light beam.
The invention has the beneficial effects as follows, while can regulating carrying out whole beam path alignment, easy disassembly, structure is simple, and easy for installation, each funtion part is relatively independent, can directly increase or reduce function number of tubes, versatility is better, can adaptive sizes, functional lens.
