Abstract
The invention provides a coarse-pitch one-dimensional vertical lifting adjustment rack which comprises a fixing sleeve, a sliding shaft, a screw, a pressing sleeve, a thread sleeve and a slide block, wherein the sliding shaft is inserted into a shaft hole of the fixing sleeve and can slide; one end of the slide block penetrates through a guide groove of the fixing sleeve and is fastened on the sliding shaft; the other end of the slide block is inserted into a spiral groove in the thread sleeve; the spiral groove drives the slide block to lift in rotating and drives the sliding shaft to slide and lift up and down; and the pressing sleeve is arranged at the upper end of the thread sleeve and fixed on the fixing sleeve by set screws, limits the thread sleeve, and only allows the thread sleeve to rotate around a shaft center of the sliding shaft. The one-dimensional vertical lifting adjustment rack has the structural advantages that the fastening is convenient and quick; the assembling is convenient; an overall span of the thread sleeve is small; the pitch is coarse; the lifting is adjusted more conveniently; and the sliding shaft works stably without swinging. The adjustment rack can adjust stably, conveniently and quickly in the vertical direction and is convenient to use and high in efficiency, and the vertical lifting is accurate.
Description
Technical field
The present invention relates to the VTOL (vertical take off and landing) governor motion in a kind of optical beam path experiment, particularly a kind of coarse pitch VTOL (vertical take off and landing) one dimension adjusting bracket that does not deflect in adjusting lifting process axle center.
Background technology
When the optical Properties light path is furnished, be very general demand to the optical element lift adjustment.And existing regulating measure is when regulating, and optical element swings, axial deflection etc. often occur and regulates wild effect, thereby causes the light path ornaments difficult, adjusts loaded down with trivial details.Owing to these reasons, only cause in optical element VTOL (vertical take off and landing) adjustment process, a large amount of elapsed times cause conventional efficient low, and affect experimenter's job morale.
Summary of the invention
For solving above-mentioned technical matters, purpose of the present invention provides a kind of coarse pitch VTOL (vertical take off and landing) one dimension adjusting bracket, is convenient to install in the light path test, the convenient adjustable height of regulating; Adjusting bracket clamping optical element only exists axially and moves up and down in the adjustment process, can not occur to swing and the phenomenon such as axle center deflection.
For achieving the above object, the technical solution used in the present invention provides a kind of coarse pitch VTOL (vertical take off and landing) one dimension adjusting bracket, and wherein: described lifting one dimension frame includes fixed cover, sliding axle, screw, gland, thread bush, slide block; Described sliding axle inserts in the fixed cover axis hole and can slide, the gathering sill that one end of slide block passes fixed cover is fastened on the sliding axle, the other end of slide block inserts the helicla flute in the thread bush, thread groove band movable slider lifting during rotation drives sliding axle and slides up and down lifting, be provided with gland in the thread bush upper end, gland is fixed on the fixed cover by holding screw, and gland double thread cover carries out spacing, only allows thread bush to take in the axle center of sliding axle as the rotation center rotation.
Helicla flute pitch in the described thread bush is 8mm.
Effect of the present invention is that this structure has following advantage: 1, fastening convenient, easy to assembly; 2, the total span of thread bush is little, and the large adjusting lifting of pitch is more convenient; 3, sliding axle working stability is without swinging.From ergonomics, assembling and operation are all very convenient, and the thread bush outside surface does not design with traditional anti-slip veins, but has used the corrugated appearance design, the experimenter's operation of being more convenient for.Its vertical direction modification stability, convenient, VTOL (vertical take off and landing) is accurate, and is easy to use, and efficient is high.

Embodiment
Be illustrated below in conjunction with the structure of accompanying drawing to coarse pitch VTOL (vertical take off and landing) one dimension adjusting bracket of the present invention.
As shown in Figure 1, coarse pitch VTOL (vertical take off and landing) one dimension adjusting bracket of the present invention, described lifting one dimension frame includes fixed cover 1, sliding axle 2, screw 3, gland 4, thread bush 5, slide block 6.
Described sliding axle 2 inserts in fixed cover 1 axis hole and can slide, the gathering sill that one end of slide block 6 passes fixed cover 1 is fastened on the sliding axle 2, the other end of slide block 6 inserts the helicla flute in the thread bush 5, thread groove band movable slider 6 liftings during rotation, drive sliding axle 2 and slide up and down lifting, be provided with gland 4 in thread bush 5 upper ends, gland 4 is fixed on the fixed cover 1 by holding screw 7, gland 4 double threads cover 5 carries out spacing, only allows thread bush 5 take the axle center of sliding axle 2 as the rotation center rotation.Helicla flute pitch in the described thread bush 5 is 8mm.Sliding axle 2 ranges are 20mm, still are retained in the interior length of fixed cover 1 axis hole when sliding axle 2 rises to the limit greater than the diameter of 1.5 times of sliding axles.
The coarse pitch VTOL (vertical take off and landing) one dimension adjusting bracket that the present invention carries includes: fixed cover 1, sliding axle 2, screw 3, gland 4, thread bush 5, slide block 6, holding screw 7.Assembling process is as follows:
Sliding axle 2 is installed in the axis hole of fixed cover 1; Slide block 6 passes the gathering sill of fixed cover 1, is fastened on the sliding axle 2; Be coated with on the thread groove with thread bush 5 and spread railway grease and pass fixed cover 1, rotation thread bush 5 makes slide block, and 6 enter the thread groove of thread bush 5 and prop up the bottom shaft shoulder of fixed cover 1; Gland 4 is screwed into the screw thread of fixed cover 1, and adjusts the position of thread bush 5, can rotate freely, but play up and down.Two holding screws 7 are screwed into the screw of gland 4, prevent that gland 4 is loosening, respectively screw 3 is screwed into the reservation screw of fixed cover 1 and sliding axle 2 upper ends.
Coarse pitch VTOL (vertical take off and landing) one dimension adjusting bracket function of the present invention is achieved in that
