Description
Technical field:
The present invention relates to accurate adjustment rack, is that two-dimentional link-type two plate structures are rotated accurate adjustment rack.Be mainly used in the adjusting mechanism of precision optics and precision optical machinery.As the accurate angular setting in the light path adjustment.
Background technology:
The optical precision adjusting mechanism is one of necessary tool in Experiments of Optics, the optic test, and its major function is to realize that the transposition of angular setting peace is whole.The form of optical precision adjustment rack, adjustment dimension, method of adjustment have nothing in common with each other, but with regard to the agent structure relation, can be reduced to two flat boards--the spatial relation between fixed flat planar and the exercise stress basically, promptly so-called two plate structures.In two traditional plate structure two dimension angular optical adjusting frames, primary structure comprises fixed flat planar, exercise stress and is connected between the two adjustment screw.Adjust the driving link of screw, form screw thread pair, make the rotation that is applied on the adjustment screw be converted into translation, thereby realize adjustment exercise stress with fixed flat planar or exercise stress as mechanism kinematic.Two traditional plate structures are often by adopting flexible member between exercise stress and fixed flat planar, wait the to-and-fro movement that guarantees that exercise stress is in course of adjustment as extension spring, play the function of eliminating thread pitch simultaneously, but because of the use of mechanism's medi-spring has reduced mechanism's whole rigidity, promptly cause the decline of the resonant frequency of mechanism, so in the higher occasion of stability requirement, certain restriction that the application of this kind mechanism just is subjected to.Two traditional in addition plate structures are when adjusting, and the precision of its adjusting is only relevant with the distance L of the pitch p that adjusts screw, adjustment screw and rotating fulcrum, i.e. adjusting angle θ=p/L; With pitch 0.5mm, the distance of adjusting screw and rotating fulcrum is an example for 100mm, and the angular adjustment precision is 0.3 °, so the precision of adjusting angle is difficult to reach the requirement of second class precision.
Summary of the invention:
The technical problem to be solved in the present invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of two-dimentional link-type two plate structures to rotate accurate adjustment rack, it should have simple in structure, process and assemble convenience, good stability, big adjusting amplification ratio, cheap characteristics.
Technical solution of the present invention is as follows:
A kind of two-dimentional link-type two plate structures are rotated accurate adjustment rack, are characterized in comprising that mirror holder fixed flat planar, mirror holder exercise stress, two have straight-bar and an adjusting gear that the linkage assembly of joint ball bearing, an end have the joint ball bearing.
Described mirror holder fixed flat planar and the mirror holder exercise stress linkage assembly that has the joint ball bearing by being positioned at same diagonal line two ends be positioned at the straight-bar that another diagonal line one end has the joint ball bearing and link to each other, and keep being parallel to each other.The installation axis of the installation axis of linkage assembly upper joint ball bearing and straight-bar upper joint ball bearing is parallel to each other, and each linkage assembly upper joint ball bearing center is vertical mutually with straight-bar upper joint ball bearing center.
Described linkage assembly is made up of the last connecting rod and the lower link that have the joint ball bearing, the joint ball bearing of last connecting rod links to each other with the mirror holder exercise stress, the joint ball bearing of lower link links to each other with the mirror holder fixed flat planar, last connecting rod links to each other by drive pin with lower link, and pass drive pin with split pin, with drive pin loosening be fixed on upper and lower connecting rod place.
Described adjusting gear is the motor adjusting gear, and its supporting seat one end links to each other with the mirror holder fixed flat planar, and the other end links to each other with motor cabinet.Motor is installed on the motor cabinet, rotates and realize the relative translation of screw mandrel and drive-type shaft coupling by drive-type coupling band movable wire bar.Screw mandrel passes the screw mandrel cover on the motor cabinet and connects by pin with bearing seat.Drive ball head rod one end links to each other with bearing seat by self-aligning ball bearing, the other end is equipped with the joint ball bearing and links to each other with drive pin by the joint ball bearing, come the drive link motion of mechanism by drive pin, realize the angular adjustment of mirror holder fixed flat planar and mirror holder exercise stress.
Described adjusting gear is a manual adjusting device, its formation is: a supporting seat one end is connected and fixed flat board, one end of one screw mandrel links to each other with handle by pin, after the other end of this screw mandrel is installed in screw mandrel cover on the supporting seat, link to each other with bearing seat by pin, one end of drive ball head rod is equipped with the joint ball bearing, hole, garden on this joint ball bearing and the drive pin matches, tighten up by holding screw, the other end of drive ball head rod is fixed on self-aligning ball bearing on the drive ball head rod by screw, and this self-aligning ball bearing then matches with bearing seat.Rotate handle by hand and drive screw mandrel promotion drive ball head rod, realize the motion of exercise stress, finish required angular adjustment with respect to fixed flat planar by upward connecting rod and lower link rotation of drive pin drive.
Advantage of the present invention:
These two-dimentional link-type two plate structures are rotated the simple in structure of accurate adjustment rack, and are lower to the requirement of element manufacturing and assembling, are convenient to produce in batches; Because adjustment rack adopts bar linkage structure, has realized being rigidly connected between two plates, therefore improved the stability of adjustment rack device integral body; The secondary that likens to precision adjustment usefulness of the chord length of its end movement locus and action amplifies when utilizing the connecting rod rotation simultaneously, significantly improved the adjustment precision, therefore in high stability, the optics of high-precision requirement is adjusted in the trim has great superiority and promotional value.
