Abstract
The utility model relates to the field of mechanical equipment, be a laser beam machining focus control system, a laser numerical control focus axle specifically says so. This laser numerical control focus axle mainly includes: parts such as servo motor 1, planet gear 2, drive shaft coupling 3, ball 4, linear guide 5, cutting head 6, fixed slide 7. Cutting head 6 relies on linear guide system 5 and 7 hookups of fixed plate to can follow the guide rail reciprocates. Servo motor 1 realizes the servo drive through planet gear 2, shaft coupling 3 etc. And ball 4 hookup. Ball 4 rotate to drive 6 parts of cutting head and reciprocates, contains focusing lens, the automatic focal point of laser placement position that changes from this in the cutting head 6. The utility model has the advantages that: the efficiency of the laser perforation is greatly improved, having shortened the time of adjusting the focus when changing technological parameter, having relied on the position of servo automatic control laser cutting focus, the speed response is fast, and position adjustment is accurate, the degree of automation height.

A kind of laser numerical control focal axis includes: servomotor, planetary reduction gear, driving shaft coupling, ball-screw, line slideway, cutting head, fixed glides, described laser numerical control focal axis Z-direction increases by one for individually changing the axis servomotor that cutting head lens are unknown.
Wherein, described numerical control focal axis depends on main frame Z axis parts by fixed plate, it is achieved numerical control focal axis and the parallel of main frame Z axis and the perpendicular positioning with X/Y plane.
Wherein, described servomotor is connected with ball-screw by planetary reduction gear, shaft coupling, controls the rotation of ball-screw.
Wherein, described cutting head is coupled with fixed plate by line slideway, and can linearly move up and down by guide rail.
The beneficial effects of the utility model are:
1, being automatically adjusted focal position of laser, making up in process cannot the shortcoming of manual adjustment；
2, Serve Motor Control degree of regulation, focal variation amount is accurate to 0.01mm, is effectively guaranteed the technological requirement of laser cutting focus；
3, adding magnet crashproof device, when there is burst collision, numerical control focal axis departs from Z axis, and relies on 2 spring tractions fixing, and effectively protection vitals is from infringement.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings, by detailed description of the invention of the present utility model is described in detail.
Fig. 1, structural representation for the utility model a kind of laser numerical control focal axis；
Fig. 2, left view for the utility model a kind of laser numerical control focal axis.
Detailed description of the invention
By further illustrating the technological means and effect thereof that the utility model taked, it is described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.
Referring to shown in Fig. 1, Fig. 2, a kind of laser numerical control focal axis includes: servomotor 1, planetary reduction gear 2, driving shaft coupling 3, ball-screw 4, line slideway 5, cutting head 6, fixed glides 7.After digital control system receives sensor feedback signal, automatically calculating the adjustment amount of focal position, then send motor message to described servomotor 1, this process is the most extremely short, and response is exceedingly fast.
Further, servomotor 1 is by after planetary reduction gear 2, it is achieved the reduction of rotating speed and the increase of moment of torsion, ensures for quickly driving cutting head 6 motion to provide power.Shaft coupling 3 delivers the power provided by servomotor 1.
Further, ball-screw 4 moves up and down by rotarily driving nut, and feed screw nut is connected with connecting plate, and cutting head 6 is coupled with line slideway 5 by connecting plate.
Further, by moving up and down of cutting head 6, change the position of condenser lens, and then change the drop point of focus on sheet material, provide pinpointed focus technique for cutting.
After digital control system receives sensor feedback signal, automatically calculating the adjustment amount of focal position, then send motor message to servomotor 1, this process is the most extremely short, and response is exceedingly fast.
Servomotor 1 is by after planetary reduction gear 2, it is achieved the reduction of rotating speed and the increase of moment of torsion, ensures for quickly driving cutting head 6 motion to provide power.Shaft coupling 3 not only delivers the power provided by servomotor 1, also acts overload protective function.Ball-screw 4 moves up and down by rotarily driving nut, and feed screw nut is connected with connecting plate, and cutting head 6 is coupled with line slideway 5 by connecting plate.By moving up and down of cutting head 6, change the position of condenser lens, and then change the drop point of focus on sheet material, provide pinpointed focus technique for cutting.
In sum, a kind of laser numerical control focal axis that the utility model provides, substantially increase the efficiency of laser beam perforation, adjusting the time of focus when shortening Replacement procedure parameter, rely on servo-drive system to automatically control the position of laser cutting focus, speed responsive is fast, position adjustment is accurate, and automaticity is high.
The above; it is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that the utility model discloses; change can be readily occurred in or replace, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should described be as the criterion with scope of the claims.
