Description
The utility model is a kind of space multistory distribution heavy caliber focus lamp focus adjusting mechanism, relates to the multidimensional focus adjusting mechanism.
In the existing laser optical path focusing, adopt bicylindrical rolling interference axle system to support focus lamp, an accurate screw mandrel and stepper motor combination are adopted in transmission.Weak point is that bigbore amasthenic lens is when space multistory distributes, because deadweight etc. is subjected to the difference of force direction, with above-mentioned traditional guide rail mechanism focusing, guide precision requires too high, processes and debug all very difficult, the precision of guide rail is low slightly, to produce mechanism's off-centre, the focus lamp unbalance stress can not be realized uniform and stable adjusting, directly influence focusing accuracy, even can make mechanism blockage.Its focusing range has only ± 5mm, mechanical adjustment precision ± 5 μ m, and can only settle use in the horizontal direction.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art and a kind of focusing accuracy height is provided, good stability, and range of adjustment is wide, can be at the space multistory distribution heavy caliber focus lamp focus adjusting mechanism of X, Y, three directions adjustings of Z.
The purpose of this utility model can realize by following measure: space multistory distribution heavy caliber focus lamp focus adjusting mechanism, the rotation system that constitutes by accurate screw mandrel and stepper motor, make the focus lamp on the guide rail move axially focusing, the microscope base that focus lamp is housed is fixed on X, the Y two dimension precise guide rail frame, be an accurate screw mandrel of active and two the driven accurate screw mandrels by the steel wire transmission on the housing of Y guide rail bracket, initiatively accurate screw mandrel connects the harmonic gear case and by computer-controlled stepper motor.
The purpose of this utility model can also realize by following measure: be fixed with the helical screw that a transmission X guide rail bracket is done the directions X straight-line displacement on the microscope base; On the X guide rail bracket, be fixed with a transmission Y guide rail bracket and make the helical screw of Y direction straight-line displacement.
The utility model is compared prior art and is had following advantage:
1. adopting computer-controlled stepper motor to make the harmonic gear case drive initiatively accurate screw mandrel rotates, and two driven accurate screw mandrels and accurate screw mandrel initiatively are synchronized with the movement through the transmission of steel wire pretension, improved adjustment sensitivity, regulate resolution reach ± 1.3 microns, when under any focus lamp axis angle, working, all can guarantee space multistory distribution heavy caliber focus lamp in the stable regulation of axially focusing, its stability reaches 0.026 micron.
2. the three-dimensional regulation structure that adopts X, Y coarse adjustment on a large scale and Z to combine to minute adjustment improves focusing accuracy, enlarges focusing range, and its minute adjustment precision is ± 1.135 microns, and the minute adjustment scope reaches ± and 10 millimeters.
3. the utility model is simple in structure, precision is high, processing is debug all very convenient and mechanical operation is flexible.
