In mechanical processing process, error is ubiquitous, small to error caused by machine components processing, big to assembling
Error produced by journey.Error not only results in the angle that laser beam deviates setting, influences focal position, but also can make laser beam
Generated focus deviates gas nozzle axis, in some instances it may even be possible to and have part of laser beam direct irradiation makes gas nozzle melt on gas nozzle,
Butt welding spot intensity and appearance generate great adverse consequences, decline and scrap so as to cause properties of product.
【Invention content】
In conclusion the main purpose of the utility model be in order to solve existing coaxial inflatable body gas nozzle outlet with
The laser beam foucing focused in laser welding outgoing head is not coaxial, the technical issues of declining and scrap so as to cause properties of product,
And provide a kind of coaxial inflatable body of adjustable angle.
In order to solve the above-mentioned technical problem, the utility model provides a kind of coaxial inflatable body of adjustable angle, the machine
Structure includes：Coaxial air blowing cylinder, and it is axially upper set on the coaxial air blowing cylinder and for adjust laser beam displacement angle and/or
The coaxial gas nozzle of axial position is embedded on the outer surface of the coaxial gas nozzle tail portion and is fitted closely with the inner wall of coaxially air blowing cylinder
Elastic seal ring, be spaced apart at the proximal edge of the coaxial air blowing cylinder front end and be equipped with multiple screw holes, on each screw hole point
It is not threaded with and gas nozzle is locked or is unclamped to adjust the adjusting screw of gas nozzle angle, the end section of the coaxial gas nozzle
It is inserted in the coaxial air blowing cylinder leading inside to seal the coaxial air blowing cylinder, and is consolidated coaxial gas nozzle by the adjusting screw
It is fixed.
The coaxial gas nozzle include a shell, and in the shell for for laser beam by taper chamber,
An annular groove is offered in the circumferential direction of the shell rear end surface, the elastic seal ring is embedded in the annular groove.
The width of the elastic seal ring is more than the depth of the annular groove.
The internal diameter of the taper chamber tail end of the coaxial gas nozzle is more than the internal diameter of its head end.
The axis perpendicular of the adjusting screw and the coaxial air blowing cylinder, by adjusting coaxial gas nozzle in coaxial air blowing cylinder
In relative position, with deviation angle of the calibration of laser light beam in coaxial air blowing cylinder, to make coaxial gas nozzle and laser beam
Tend to be concentric.
Using above-mentioned technical proposal, compared with prior art, advantageous effect caused by the utility model is：Gas nozzle can
With according to laser beam deviate situation make angle and axial direction can fitting adjust, make laser spot be in gas nozzle export most preferably away from
From on axis.The features such as the utility model has simple and reliable for structure, simple and direct-viewing operation, and using effect is good.
