Abstract
The utility model discloses a high-stability fine tuning stand which comprises an upper flat plate with chamfering quadrangles and a lower flat plate with chamfering quadrangles. A lens is clamped on the lower flat plate. Four flexible bodies are disposed between the upper flat plate and the lower flat plate. One side wall of the upper flat plate is provided with two screw holes. Each of four sidewalls of the lower flat plate is provided with a screw hole, wherein axes of all the screw holes intersect at a central point of the lower flat plate. The upper flat plate is equipped with four internal screw holes that are symmetrical to each other, a long screw rod is screwed in each internal screw hole, and a lower end of each long screw rod abuts against the lower flat plate. A through hole is arranged between the upper flat plate and the lower flat plate. The flexible bodies of the high-stability fine tuning stand exhibit fine stability and plastic deformation of the flexible bodies are not liable to occur if the stand is used for a long period of time. Moreover, the high-stability fine tuning stand is high in adjusting precision.
Description
Technical field
The utility model relates to a kind of high stability fine setting seat.
Background technology
When doing Experiments of Optics, often need be with finely tuning the attitude that seat fixes lens and adjusts lens.At present commercially available fine setting seat all adopts the mode that spring connects, accurate screw rod is adjusted, and its shortcoming is the poor stability of spring, of long duration plastic yield can take place.
The utility model content
The purpose of this utility model provides a kind of high stability fine setting seat, the good stability of flexible body, and plastic yield can not take place in long-time use, and adjusts the precision height.
The technical solution of the utility model is as follows:
A kind of high stability fine setting seat, comprise and have the tetragonal upper flat plate of chamfering, dull and stereotyped down, following dull and stereotyped upward clamping has lens, pad is provided with four flexible bodies between upper flat plate and the following flat board, have two threaded holes on upper flat plate one sidewall, have axis on following dull and stereotyped four sidewalls and meet at down threaded hole on the dull and stereotyped central point, have the internal thread hole of four symmetries on the upper flat plate, screwed togather long threaded rod in the internal thread hole, the lower end of long threaded rod installs on following flat board, is provided with through hole between upper flat plate, the following flat board.
Described long threaded rod is positioned at flexible body one side.
Described upper flat plate, down between dull and stereotyped, four flexible bodies for the entity connection, adopt a block of material one to process.
Described upper flat plate, following material dull and stereotyped, four flexible bodies can be aluminium, steel metal or alloy material.
The utility model high stability fine setting seat is processed into by a block of material, material can be aluminium, steel metal or alloy material, being entity between the each several part connects, the i.e. following flat board of the flexible body of the upper flat plate that is connected with other devices, four symmetries and clamping lens, upper flat plate is identical with following panel size, is the quadrilateral that has chamfering.At the fine setting seat through hole is set, through hole passes upper flat plate, flexible body and dull and stereotyped down, be provided with four uniform threaded holes in four dull and stereotyped down sides, the axis of four threaded holes is given down dull and stereotyped symcenter point, lens can be positioned over part dull and stereotyped under being positioned in the through hole, the screw rod that cooperates in the threaded hole can be fixed lens.A side of upper flat plate is provided with two threaded holes, is used for being connected to a fixed with other experimental provisions.The interarea of upper flat plate is provided with 4 symmetrical vertical in dull and stereotyped down internal thread hole, flexible body is just in time avoided in the position of internal thread hole, long threaded rod in the internal thread hole can arrive on the flat board, can realize adjusting the attitude of upper flat plate by the long threaded rod that turns in the internal thread hole, and then adjust the attitude of lens.

Embodiment
Referring to accompanying drawing, a kind of high stability fine setting seat, comprise and have the tetragonal upper flat plate 1 of chamfering, following dull and stereotyped 3, clamping has lens on following dull and stereotyped 1, pad is provided with four flexible bodies 2 between the upper flat plate 1 and following dull and stereotyped 3, have two threaded holes 5 on upper flat plate 1 one sidewalls, have axis on following dull and stereotyped 3 four sidewalls and meet at down threaded hole 4 on the dull and stereotyped central point, have the internal thread hole 6 of four symmetries on the upper flat plate 1, screwed togather long threaded rod in the internal thread hole 6, long threaded rod is positioned at flexible body one side, and the lower end of long threaded rod installs on following flat board, upper flat plate 1, be provided with through hole 7 between following dull and stereotyped 3.
In order to verify the stability of the described high stability fine setting of claim 1 seat, built experimental provision as shown in Figure 2.Utilize two threaded holes 5 of upper flat plate 1 one sides will finely tune seat and be fixed on one above the stilt, dull and stereotyped 3 paste a slice plane mirror down, going the angle of measurement plane catoptron to change the stability that can reflect the fine setting seat with Reinshaw three beam angle interferometers.The stability measurement result of the described high stability fine setting of claim 1 seat as shown in Figure 3.Measuring with spring with similar mode is the stability of elastomeric general commercial fine setting seat, and its result as shown in Figure 4.Comparison diagram 3 and Fig. 4 can find that when long-time the use, the stability of the described high stability fine setting of claim 1 seat is better.
