Technical field
The utility model laser cutting machine optical path compensation mechanism relates to a kind of optical path compensation mechanism, and particularly a kind of laser cutting machine optical path compensation mechanism belongs to laser weld cutting field.
Technical background
On laser cutting machine, the beam Propagation of carbon dioxide laser output passes through mirror reflects again to different distance, utilizes the transmission-type focus lamp laser facula that area is bigger to gather the laser beam that becomes to have high power density again, just can be used for cut.Be called outside optical system from the laser instrument output window to the device the workpiece to be machined.In cutting process, cutting head carries out the motion of X, Y direction, and it is flight light path that light beam moves form.Because the restriction of light path effective range, effective cut coverage of general cutting head is 1.5Mx3M.
For further expansion of laser light cut coverage; More existing patents have proposed some and have related to the corrective measure of light path aspect in the prior art field; As a kind of optical path compensation axle that is arranged on laser cutting machine lathe bed one side is provided; It at the directions X of laser cutting machine through the moving of one group of middle speculum, thereby the motion light path that the intermediate transfer light path is shortened effectively make whole cutting head increases.Can make effective cut coverage of cutting head reach 2Mx6M after adopting this device at present.Set forth following characteristic in claims of this utility model patent of having authorized 200920206345.7: the fixed length axle that is positioned at lathe bed one side is provided with two relative reflecting optics, and the speed of service of fixed length axle is the speed of service half the of crossbeam; Two reflecting optics are parallel to each other; Laser instrument is positioned at the middle of lathe bed.
Though above patent has been carried out certain improvement, also exist the manufacturing cost height, take up an area of the little deficiency of the big and effective cut coverage in space.
The utility model content
The purpose of the utility model is, through a kind of laser cutting machine optical path compensation mechanism is provided, reduces manufacturing cost; Change laser instrument and lay direction; The speed ratio of the speed of service of change fixed length axle and the speed of service of crossbeam can make that the compensation of light path is more reasonable, through the ball line slideway that replenishes; Make the optical path compensation device more steady, can reach the purpose of optical path compensation better.
The utility model is to adopt following technological means to realize:
A kind of laser cutting machine optical path compensation mechanism, laser instrument is placed in cutting machine lathe bed one side, and parallel with the cutting machine lathe bed; Move a monolateral shared ball line slideway of seat and portal frame, establish the ball line slideway of a special use in the one-sided bottom of cutting machine lathe bed, make move seat when motion up and down two groups of guideways support and retrain; Move at this and to be provided with the 3rd laser mirror sheet and the 4th laser mirror sheet on seat; Laser beam is positioned at the eyeglass of laser cutting head top through being refracted to of a plurality of laser mirror sheets; Wherein, Inject to the first laser mirror sheet from laser instrument laser and form light path L1; Be refracted to the second laser mirror sheet from the first laser mirror sheet and form light path L2; Be refracted to the 3rd laser mirror sheet from the second laser mirror sheet and form light path L3; Be refracted to the 4th laser mirror sheet from the 3rd laser mirror sheet and form light path L4, be refracted to the 5th laser mirror sheet from the 4th laser mirror sheet and form light path L5, be refracted to the 6th laser mirror sheet from the 5th laser mirror sheet and form light path L6;
Also be provided with adjustment portal frame and the decelerator that moves the seat speed ratio.
Aforesaid portal frame is 1.8: 1 with the speed ratio that moves seat.
Aforesaid decelerator is specific speed ratio.
A kind of laser cutting machine optical path compensation of the utility model mechanism compared with prior art, has following remarkable advantages and beneficial effect:
A kind of laser cutting machine optical path compensation of the utility model mechanism follows motor from electric upward original major axis motor being changed into, adjusts speed ratio with decelerator again, has reduced manufacturing cost.Direction is laid in existing laser instrument change; Practiced thrift the site area that user's machine is installed and used; Because former high-power carbon dioxide laser length is mostly more than 2 meters, so laser instrument is vertical with the cutting machine lathe bed by putting occupying the very big site area of user.Adjusted portal frame and the speed ratio that moves seat, the translational speed of portal frame is 1.8 times of mobile seat translational speed, can make that the compensation of light path is more reasonable.Increase a ball line slideway, made the optical path compensation device more steady, can reach the purpose of optical path compensation better.
