Description

Laser cutting head automatic focusing device
Technical field
It the utility model is related to sheet metal cutting equipment field, especially laser cutting head automatic focusing device.
Background technology
It is well known that laser cut metal plate has unrivaled advantage, advantage is that cutting accuracy is high and disconnected Face Glabrous thorn, no matter slab or thin plate are attained by good cutting effect.However, cutting effect all with laser spot Control is inseparable.Focal point control is laser when cutting the plate of different materials and different-thickness, in order to reach more Good cutting effect, the focus of laser beam can all be set at various height, that is, position of focusing.In laser cutting application in early days, Focusing is relied primarily on manually to complete, nowadays as the development of laser technology, the requirement of cutting efficiency improve, manual focusing Mode is gradually eliminated, and the advantage of automatic focusing function starts to be showed.
Automatic focusing function, when processing the workpiece of unlike material, different-thickness, machine automatically can quickly adjust focus To most suitable position.The processing efficiency of laser cutting machine can be so significantly improved, the slab aperture time also can significantly reduce. Regulative mode is huge for servomotor and driving Separated type combination, volume used by each manufacturer is to laser automatic focusing field at present Greatly, it is complicated to dock lathe control signal, positions and repetitive positioning accuracy error is larger so that work piece cut surface does not reach ideal Effect, cutting surfaces are uneven, and adjusting process stability is inadequate, and power consumption penalty is high, and noise is big, its basic reason is to expire The accurate positionin of sufficient laser spot is adjusted and caused.
Utility model content
The technical problems to be solved in the utility model is:It is inaccurate not in order to solve existing laser cutting head focusing Foot, the utility model provide a kind of laser cutting head automatic focusing device, by the way that motor and driving are integrated in laser cutting head One, accurately auto-focusing is realized using motor and drive control.
Technical solution is used by the utility model solves its technical problem:
A kind of laser cutting head automatic focusing device, including lens barrel, the lens barrel are fixedly connected with the quill in motor, Quill is slidably connected with fixed seat, and motor and grating scale are fixedly connected in fixed seat, quill with by focal position The feedback controller that information feeds back to machine tool control system is fixedly connected, feedback controller side and the measurement end face phase of grating scale Fitting.
Through the above technical solutions, the quill and motor internal in motor are all wound with coil, quill is put into In fixed seat, after energization, magnetic force is produced, quill is suspended in fixed seat, so as to allow quill along fixed seat end Slided up and down on track on face, by varying the size of coil current, and then change the size of magnetic force, played adjusting and make With.When quill moves up and down, feedback controller can be driven to be moved up and down along grating scale, so as to read light Positional information on grid ruler.
Specifically, the quill is fixedly connected with the lens cone by lens barrel lock.
Through the above technical solutions, being bolted to connection using lens barrel lock one end with lens barrel, lens barrel lock is another End is fixedly connected with the lens cone by bolt.
Specifically, the lens barrel lock is fixedly connected by bolt with feedback controller.
Through the above technical solutions, it is bolted so that feedback controller can be by lens barrel lock and quill Drive moves up and down.
Specifically, the lens barrel lock side is equipped with spacing fixed plate, and spacing fixed plate end face, which is equipped with, to be used for limiting mirror The limit switch of cylinder lock stroke range.
Through the above technical solutions, lens barrel lock is blocked using the limit switch in spacing fixed plate, so that lens barrel Lock is limited in the range of limit switch.
The beneficial effects of the utility model are:The utility model provides a kind of laser cutting head automatic focusing device, passes through Motor and driving are integrated in laser cutting head one, accurately auto-focusing is realized using motor and drive control.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the utility model;
1. lens barrel in figure, 2. motors, 3. quills, 4. fixed seats, 5. grating scales, 6. feedback controllers, 7. lens barrels lock Seat, 8. spacing fixed plates, 9. limit switches.
Embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram, Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows the composition related with the utility model.
Fig. 1 is the structure diagram of the utility model.
A kind of laser cutting head automatic focusing device, including lens barrel 1, the lens barrel 1 are fixed with the quill 3 in motor 2 Connection, quill 3 is slidably connected with fixed seat 4, and motor 2 and grating scale 5 are fixedly connected in fixed seat 4, quill 3 and The feedback controller 6 that focal position information is fed back to machine tool control system is fixedly connected, 6 side of feedback controller and grating scale 5 measurement end face fits.The quill 3 is fixedly connected by lens barrel lock 7 with lens barrel 1.The lens barrel lock 7 passes through Bolt is fixedly connected with feedback controller 6.7 side of lens barrel lock is equipped with spacing fixed plate 8, on spacing 8 end face of fixed plate Equipped with for limiting the limit switch 9 of 7 stroke range of lens barrel lock.
As shown in Figure 1, machine tool control system sends signal designation and outputs signal to motor 2 by driver computing, electricity Coil is all wound with inside quill 3 and motor 2 in machine 2, quill 3 is sleeved on the slide of fixed seat 4, after energization, Produce magnetic force, quill 3 is suspended in fixed seat 4, thus allow quill 3 along the track on 4 end face of fixed seat into Row slides up and down, it is achieved thereby that motor carries out focal adjustments with the focus lamp in moving lens barrel 1.When quill 3 is on carrying out When lower mobile, feedback controller 6 can be driven by quill 3, and be moved up and down along grating scale 5, so as to allow feedback to control Device 6 processed obtains focal position information, positional information is then fed back to machine tool control system, machine tool control system is further according to cutting Focal position needed for plate, output order to driver, is reacted in time by driver, to control the straight line of motor 2 to transport It is dynamic, so as to adjust focus.
Using the above-mentioned desirable embodiment according to the utility model as enlightenment, pass through above-mentioned description, related work people Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real The content being not limited to new technical scope on specification, it is necessary to which its technology is determined according to right Property scope.
