Description
Technical field
The utility model belongs to the laser process equipment technical field, is specifically related to a kind of laser cutting head hunting gear.
Background technology
In the laser cutting, nozzle be one of principal element that determines kerf quality and cutting speed by the distance on cut spare surface, during cutting, nozzle must keep stable and consistent to the height that is cut surface of the work.Traditional laser cutting head has only condenser lens and nozzle, there is not automatic focus function, when big width laser cuts, particularly under the not high situation of cutting thin plate, material surface flatness, different local nozzles are different to the height that is cut surface of the work, cause to be cut material surface and to depart from focal length, focal beam spot varies in size, power density is also different, causes in the different parts cut quality inconsistently, does not reach the quality requirement of laser cutting.
Referring to accompanying drawing 1, traditional hunting gear generally adopts the Double Circle guide rail, except sleeve 12, also will increase a guide post 14.In this structure, ball-screw only plays the driving effect, to guarantee simultaneously that distance and the depth of parallelism between ball-screw and two circular guideways are relatively more difficult, usually want ball-screw or guide post axle head bearing position adjustable, be that bearing block 1 and 8 needs up-down adjustment, complex structure, assembling difficulty, nozzle moves up and down dumb, and reaction is slow.
The utility model content
For overcoming above-mentioned deficiency, the purpose of this utility model is to provide a kind of distance that makes laser nozzle and cut between the surface of the work to regulate automatically, focusing automatically all the time, the laser cutting head hunting gear of assurance excision forming unanimity.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of laser cutting head hunting gear, comprise stepper motor, shaft coupling, bearing block one, axle head supporting one, rolling bearing one, nut seat, ball-screw nut, ball-screw, rolling bearing two, axle head supporting two, bearing block two, sleeve, nozzle, described stepper motor is connected with ball-screw by shaft coupling, rolling bearing one is fixed on the bearing block one by axle head supporting one, rolling bearing two is fixed on the bearing block two by axle head supporting two, described rolling bearing one and rolling bearing two are connected by ball-screw, nut seat cooperates with the ball-screw nut end face, radially gapped, barrel forward end is provided with nozzle, nozzle is isolated from the outside by felt pad one and felt pad two, and locked by locking nut, milled out half-arc groove on the periphery of locking nut, mill out the semi arch cylinder that the half-arc groove with locking nut adapts in the endoporus of adapter sleeve, be embedded with straight pin between locking nut and the felt pad one, straight pin matches with the half-arc groove of locking nut.
Compared with prior art, the utlity model has following beneficial effect: the utility model reduces by a guiding rail, and ball-screw plays transmission and guide effect simultaneously; Nut tuno-miller half-arc groove and straight pin are used, and play good anti-loosing effect; Adopt capacitive sensing, signal of telecommunication control step motor rotates, and can make laser nozzle and regulate automatically with the distance of being cut between the surface of the work, focus automatically all the time, and assurance excision forming unanimity, attractive in appearance, no burr improves cut quality and cutting efficiency greatly.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated
Referring to accompanying drawing 2, Fig. 3, a kind of laser cutting head hunting gear, comprise stepper motor 1, shaft coupling 2, bearing block 1, axle head supports 1, rolling bearing 1, nut seat 6, ball-screw nut 7, ball-screw 8, rolling bearing 29, axle head supports 2 10, bearing block 2 11, sleeve 12, nozzle 13, described stepper motor 1 is connected with ball-screw 8 by shaft coupling 2, rolling bearing 1 supports 1 by axle head and is fixed on the bearing block 1, rolling bearing 29 supports 2 10 by axle head and is fixed on the bearing block 2 11, described rolling bearing 1 is connected by ball-screw 8 with rolling bearing 29, nut seat 6 cooperates with ball-screw nut 7 end faces, radially gapped, sleeve 12 front ends are provided with nozzle 13, nozzle 13 is isolated from the outside by felt pad 1 and felt pad 2 18, and by locking nut 15 lockings, milled out half-arc groove 20 on the periphery of locking nut 15, mill out the semi arch cylinder that the half-arc groove 20 with locking nut 15 adapts in the endoporus of adapter sleeve 16, be embedded with straight pin 19 between locking nut 15 and the felt pad 1, straight pin 19 matches with the half-arc groove 20 of locking nut 15.
Capacitive sensing control step motor 1 rotates, drive ball screw assembly, 7 actions by shaft coupling 2, thereby drive sleeve 12 is mobile in the circular hole guide rail, be that nozzle 13 is regulated automatically along vertical surface of the work direction, laser beam focuses on through the condenser lens in the sleeve 12, by nozzle 13 ejections, the automatic adjusting of nozzle 13 has guaranteed laser beam automatic focus.Ball-screw 8 also has guide effect except the rotation with motor 1 changes sleeve 12 rectilinear motions into, namely limit sleeve 12 around the rotational freedom of its axis.Nut seat 6 and ball screw assembly, 7 only end face cooperate, and big gap is radially arranged, therefore when processing and assembling, only need guarantee axle head support 1 and axle head support 2 10 equal altitudes, can guarantee the depth of parallelism of ball-screw 8 and sleeve 12, guarantee that sleeve moves flexibly.
