Description
Technical field
The invention belongs to machinery manufacturing technology field, and in particular to a kind of hole is oriented to ball linear guiding mechanism.
Background technology
In long focal length optical telescope, the focussing process for object lens of focusing, continuous vari-focus of objective with variable focal length etc. are all logical
Cross optics microscope group and moved along a straight line along optical axis and realize focusing, continuous vari-focus function.Drive the straight-line guidance machine of optics microscope group movement
Structure is divided into slidingtype and roller.Slidingtype linear guiding mechanism needs to retain certain interval to subtract between two mutual movement parts
Clamping stagnation problem is rubbed and avoids less, and gap can cause microscope group optical axis in motion process to rock, and cause the optical system optical axis steady
Determine required precision to be difficult to ensure that;Roller linear guiding mechanism is inlaid with ball between two relative motion parts, and having can be with
By applying the advantages of pretightning force eliminates gap, but the ball linear guiding mechanism of technology maturation is all real to be oriented to using axle at present
Now moving along a straight line, this spindle guide direction guiding rail structural requirement axis of guide has a sufficient length, and the axis of guide is in occupation of center, and
Optical element is distributed along optical axis order in optical system, the position Xiang Chong of the position of the axis of guide and optical element in topology layout
It is prominent, therefore existing ball-type structure is not suitable for applying to the conjunction of optics microscope group moving field.
Referring to accompanying drawing 1 and accompanying drawing 2, for the slidingtype guiding mechanism of optics microscope group movement, including Liar group 1, mirror
Seat 2, trim ring 3, pilot sleeve 4 and drive nail 5;The optics microscope group 1 being made up of some Liars is arranged in the hole of microscope base 2 and used
Trim ring 3 is fixed, and drives nail 5 to be fixed by screws on microscope base 2, so as to microscope group 1, microscope base 2 and drives nail 5 to form one;It is oriented to
There is the endoporus with 2 cylindrical matching of microscope base on sleeve 4, the endoporus on pilot sleeve 4 coordinates with the external cylindrical surface gap of microscope base 2, is oriented to
Have to allow drive on sleeve 4 and follow closely 5 grooves stretched out.
Straight-line guidance part for the slidingtype guiding mechanism of optics microscope group movement:By the endoporus and microscope base of cage guiding
It is cylindrical to coordinate realization to be oriented to;Movement transferring portion point for the slidingtype guiding mechanism of optics microscope group movement:Driving force F is acted on
The extension of nail 5 is driven, drive F drives optics microscope group 1 to be moved along a straight line along pilot sleeve 4.
In the course of the work, the power F on nail 5 is driven to drive optics microscope group 1 to be advised along pilot sleeve 4 by design by acting on
Rule moves along a straight line, and guiding accuracy depends primarily on the size of pilot sleeve 4 and the fit clearance of microscope base 2, is oriented to length i.e. microscope base
With the length of fit of pilot sleeve and the linearity of pilot sleeve endoporus, optical axis allowable angle of inclination is equal to fit clearance with leading
To the ratio of length.It is generally compact-sized in the optical system of reality, cause guiding length to reach required length, and then
Cause optical axis to rock, influence optic central extract precision, slidingtype guiding mechanism guiding length is too short also to cause motion clamping stagnation problem.
Referring to accompanying drawing 3, a kind of ball line slideway product of in the market, including by cylindrical guide 6, left end cap 7, mobile structure
Part 8, ball cover for seat 9, ball 10, retainer 11, right end cap 12;Mobile member 8, ball cover for seat 9, left end cap 7, right end cap 12 with
And retainer 11 is connected by screw and forms moving parts together, the ball 10 between moving parts and guide rail is by retainer 11
Guiding rolls along guide rail, so that movable part can be for linear motion along guide rail 6.Cylindrical guide is guiding in this structure
Part, guide rail occupy axial space, and be used to focusing in optical system, the moving element of zoom is in the axle center of moving sleeve
Position is the position of diagram middle guide 6, and is also devised with other optical elements vertically, so not allowing guide rail to ply in the centre position
Put, this structure cannot be used in the optical systems such as focusing.
