Movable base is the N-shaped structure having internal cavities, its internal cavities is provided with leading screw part and
Nut；
The output power of leading screw transmission linear stepping motor；Nut sleeve, on leading screw, is moved with the rotation of leading screw
Make and do linearly operating along slide block；
Movable base is arranged on slide block, is provided with guide rail between slide block and base；Guide rail is fixed on base
On.
Further, the bottom of described nut is provided with groove, and described slide block is stuck in this groove.
Further, the described variable hot spot control device for printer also includes:
Buffer unit；
Buffer unit is separately positioned on the both sides of nut, and takes over a job dynamic base respectively in the other two ends of elastomeric element

Any switching laws between 0.3MM；And to the large spot on printer liquid level in spot size handoff procedure
All the time same position it is in such that it is able to improve the control accuracy of hot spot with small light spot central point.
2, by arranging buffer unit, it is possible to the active force of buffering linear stepping motor so that plano-convex is saturating
The movement of mirror is the most steady.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of symbols in accompanying drawing:
Expand light path 1, planoconvex spotlight 2, movable base 3, linear stepping motor 4, leading screw 5, spring
6, nut 7, slide block 8, base 9 and guide rail 10.
Detailed description of the invention
For making the technical solution of the utility model relatively sharp, below in conjunction with the accompanying drawings the utility model is done
Explain.
Embodiment one:
The utility model provides a kind of variable hot spot for printer to control device, and it is particularly suited for
Photosensitive resin 3D printer, its structure is as it is shown in figure 1, include:
Expand light path 1, planoconvex spotlight 2, movable base 3, linear stepping motor 4, leading screw 5, spring
6, nut 7, slide block 8, base 9 and guide rail 10.
Expanding light path 1 is to be formed after light beam passes through laser amplifier, and it is projected onto planoconvex spotlight 2
On；
Planoconvex spotlight 2 is fixed on movable base 3；
Movable base 3 is the N-shaped structure having internal cavities, is provided with leading screw 5 in its internal cavities
Partly, spring 6 and nut 7；
Nut 7 is enclosed within leading screw 5, and is provided with groove bottom it, and slide block 8 is stuck in this groove,
So that nut 7 no longer rotates with leading screw 5 and does linearly operating along slide block 8；
Spring 6 is two, is separately positioned on the both sides of nut 7, and the other two ends of spring 6 are respectively
Take over a job the left side inner edge of internal cavities of moving base 3 and right side inner edge, to buffer linear stepping motor
Active force.
One end of leading screw 5 is connected with the power output shaft of linear stepping motor 4, to transmit linear stepping
The output power of motor 4；The control termination computer of linear stepping motor 4；The other end of leading screw 5
It is each passed through on the right side of the left side of movable base 3, spring 6, nut 7, movable base 3；
Movable base 3 is arranged on slide block 8, is provided with high-accuracy guide rail between slide block 8 and base 9
10.High-accuracy guide rail 10 is fixed on base 9 by screw.
The operation principle of the present embodiment one is as follows:
The utility model utilizes computer to send the rotation of leading screw 5 of signal control line stepper motor 4,
Allow nut 7 be subjected to displacement along the direction of leading screw 5, and then extrusion spring 6 indirectly gives movable base
3 one active forces of seat, so that movable base 3 and slide block 8 slide along leading screw 5 direction, because of
It is integrally fixed on movable base 3 for planoconvex spotlight 2, so planoconvex spotlight 2 is along with movable base 3
Move and move, change planoconvex spotlight 2 by which and expand light path 1 through what laser amplifier amplified
Far and near distance thus control the size of laser facula.
Above-described embodiment using spring 6 as buffer unit as a example by illustrate, but the utility model
Be not limited thereto, it is also possible to utilize other parts as buffer unit, such as elastic rubber fitting etc..
The utility model utilizes linear stepping motor to drive the displacement of planoconvex spotlight, it is possible to change plano-convex saturating
Mirror 2 and the distance expanding light path 1 distance, thus control the size of laser facula；Additionally this practicality is new
Type uses the active force of spring buffer linear stepping motor so that the movement of planoconvex spotlight 2 is the most steady.
Embodiment two:
It is not include spring 6 with the difference of embodiment one.Now the dual-side of nut 7 is against movable base
The left and right inner side edge of the internal cavities of seat 3.Movable base 3 is mobile with the action of nut 7.
Although the utility model is open as above with preferred embodiment, but embodiment is not for limiting
Of the present utility model.Without departing from the spirit and scope of the utility model, any equivalence done becomes
Change or retouching, also belong to the protection domain of the utility model.Protection domain the most of the present utility model
The content that should be defined with claims hereof is as standard.
