Description
Technical field
The present invention relates to increases material manufacturing technology fields, and in particular to a kind of adjustment mechanism for dynamic zoom.
Background technique
Growing with laser application, indicator type laser demand small in size, light-weight, high reliablity is more next
It is bigger.But this laser is in the fabrication process, concentricity but it is difficult to ensure that.
Microlaser limited by minimum installation diameter, can only be using along Laser emission direction mounted lens one by one
Method is assembled.Show that use is cumbersome in lens barrel high scale when manufacture.Although electric beam expanding lens can guarantee multiplying power transformation and hair
The precision that divergence is adjusted, but it is expensive, and volume is larger, and structure is also complex.Being badly in need of one kind can guarantee that laser is same now
Axis degree, cost is small, and does not influence the laser adjustment mechanism of optical quality.
Summary of the invention
In order to solve the above technical problems, structure is simple, body we have proposed a kind of adjustment mechanism for dynamic zoom
Product is small, at low cost, and does not influence optical quality.
In order to achieve the above objectives, technical scheme is as follows:
Adjustment mechanism for dynamic zoom comprising pedestal, drive mechanism and Zoom structure, the transmission mechanism include
The motor being packed on pedestal and the driving section being connected with the motor, the Zoom structure include big eyeglass, always equipped with big
The big eyeglass seat of eyeglass, is always equipped with the small eyeglass seat of small eyeglass and is installed between big eyeglass seat and small eyeglass seat small eyeglass
Spring, the driving section is also connected with the small eyeglass seat.
Further, the driving section includes by the motor-driven eccentric wheel, the rolling adjacent with the eccentric wheel
Wheel, the scroll wheel are mounted on the side of the small eyeglass seat.
It further, further include a micro-adjusting mechanism, the micro-adjusting mechanism includes the guide rail being mounted on the base and installation
Sliding block on guide rail, the small eyeglass seat installation is on the slide block.
Through the above technical solutions, the adjustment mechanism for dynamic zoom has the following advantages:
1, by changing the gap between big eyeglass, small eyeglass, the spot size on working face can be changed；
2, structure is simple, and processing, assembly are simple, securely and reliably, small in size and at low cost, may replace that import is electronic to be expanded
Mirror.
Detailed description of the invention
In order to illustrate the technical solution of the embodiments of the present invention more clearly, required use in being described below to embodiment
Attached drawing be briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for this
For the those of ordinary skill of field, without creative efforts, it can also be obtained according to these attached drawings others
Attached drawing.
Fig. 1 is the structural schematic diagram disclosed in the embodiment of the present invention for the adjustment mechanism of dynamic zoom.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Below with reference to schematic diagram, specific embodiments of the present invention will be described in further detail.
Referring to Fig.1, the adjustment mechanism for dynamic zoom comprising pedestal 1, drive mechanism and Zoom structure, the biography
Motivation structure includes the motor 2 being packed on pedestal 1 and the driving section that is connected with the motor 2, and the Zoom structure includes big
Eyeglass, the always big eyeglass seat 4 equipped with big eyeglass, small eyeglass are always equipped with the small eyeglass seat 6 of small eyeglass and are installed in big eyeglass seat
Spring 7 between 4 and small eyeglass seat 6, the driving section are also connected with the small eyeglass seat 6, and small eyeglass seat is in the left and right of spring
Under, there is thrust always to the left, scroll wheel is made to offset with eccentric wheel.
With continued reference to Fig. 1, the driving section includes that the eccentric wheel 8 driven by the motor 2 and the eccentric wheel 8 are adjacent
Scroll wheel 9, the scroll wheel 9 is mounted on the side of the small eyeglass seat 6.
Further include a micro-adjusting mechanism with continued reference to Fig. 1, the micro-adjusting mechanism include the guide rail 3 being mounted on the base and
Installation sliding block 5 on guides 3, the small installation of eyeglass seat 6 on the slide block 5.
The working principle of the above-mentioned adjustment mechanism for dynamic zoom is: between changing between big eyeglass, small eyeglass
The spot size on working face can be changed in gap, when motor band movable eccentric wheel rotates an angle, work of the small eyeglass seat in spring
It under, is moved horizontally along guide rail direction, the hot spot on working face changes therewith, adjustable by adjusting rotation angle
The spot size of needs on whole working face.The processing of this mechanism, assembly are simple, reliable and stable, small in size and at low cost, may replace
Import electric beam expanding lens.
What has been described above is only a preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to the present invention
Protection scope.
