Abstract
The invention discloses a lever type micrometric displacement regulating mechanism, which comprises a coarse regulation knob, a spherical top point, a lever and a fine regulation knob, and is characterized in that the lever adopts a special high-hardness steel material, the spherical top point is processed on a position at the left side of the lever, which is at a distance of 1/N of a length of an end face from the end face (N=positive infinity), the coarse regulation knob and the fine regulation knob are respectively arranged on the left end and the right end of the lever, and the centre of a knob axis and a tangent line of a section of the lever are kept at the same position. When the left coarse regulation knob is forwards rotated, the axis of the coarse regulation knob is forwards moved, the top point is moved at the same direction, after an approximate position is reached, the fine regulation knob is rotated, at the moment, when the axis of a fine regulation knob is moved at one unit of distance, the top point of the lever is only moved at a 1/N of unit of distance, and the top point is precisely moved to a required position. By utilizing the technology, any one regulation knob in the market can be changed to the high-precision regulation knob..
Description
Technical field
The invention belongs to a kind of accurate device for moving and adjusting, be applicable to being applied in optical precision processing adjustment field and other micro Process fields.
Background technology
Many measurement of micromovements instruments operationally, under being particularly applied in cryogenic conditions or vacuum condition, need trickle and accurate adjustment, to ensure sensitivity or the spatial resolution of detection system, therefore need a kind of simple to operate, regulate reliable, the regulating device that degree of regulation is very high.But existing regulating device mostly is single thread regulating device, its degree of regulation is directly related with pitch, in order to improve degree of regulation, just pitch must be reduced, the difficulty of not only processing is very big, and the too little physical strength of screw thread that also causes of pitch declines, cannot bear larger torque, serviceable life also shortens thereupon.Separately there is a kind of knob using differential thread mode to regulate, namely rotate mutually with two groups of screw threads, the difference by two groups of thread pitch carries out minute adjustment, although this mode degree of regulation can reach very high, but the very difficult control of the matching precision of two groups of screw thread process, difficulty of processing is high equally.The physical strength of the material of double thread own also requires higher.The yield rate manufactured is low, should not realize large-scale batch production manufacture.And once damage, substantially cannot keep in repair.
Summary of the invention
The present invention is directed to above-mentioned technical matters, provide a kind of simple and practical method, by the combination of two STRTHD knobs, middlely to connect with lever, obtain a kind of micro-mobile regulating device of precision according to the principle of work of lever and trigonometric function principle.
Technical solution of the present invention is:
A kind of level type regulating structure for micro displacement, its lever main body is direct rod shape structure; Summit is located at the position apart from lever left side length N/mono-, for supporting goods; Rotation axis fulcrum is two, and it is in the position of other side close to lever two ends of lever relative to summit; Adjustment knob is placed in below fulcrum, extends to the direction away from lever; During adjustment knob, it acts on the rotation axis fulcrum be in contact with it, and lever can rotate using other rotation axis fulcrum beyond this rotation axis fulcrum as balance pivot, and meanwhile, summit produces corresponding displacement according to the motion conditions of lever and promotes cargo movement.
Described lever adopts special high precision steel, and adjusting knob is any a common knob on the market.
Preferably, described level type regulating structure for micro displacement, is provided with leg at adjustment knob away from one end of lever, for fixing, support adjustment knob.
Preferably, rotation axis fulcrum is two, is in lower-left end and the bottom righthand side of lever respectively.
Preferably, with the lever one end residing for summit for near-end, what described fulcrum near-end assembled is coarse regulation knob, and this knob is installed vertical with lever; Fulcrum far-end installs the whole knob of accurate adjustment, the installation site of the whole knob of accurate adjustment and coarse regulation knob are 0 ~ 89 degree of angle, when left side coarse regulation knob forward moves, fulcrum in the same way same distance moves, after arriving desired location, change and moved by the whole knob of accurate adjustment, because there is angle between the whole knob of accurate adjustment and lever, according to trigonometric function principle, this angle is less, then adjust that the displacement of rotation axis is easier to be controlled by knob, namely move precision higher.Now, the distance of the every mobile unit of the whole knob of accurate adjustment, the distance of the fulcrum of lever only mobile N/mono-unit, the i.e. whole rotation axis of accurate adjustment often mobile a millimeter, then fulcrum only mobile N/mono-millimeter.
Preferably, described two adjustment knobs, all can carry out screw thread rotation, its mode of motion is central shaft radial motion.
Preferably, the rotation axis fulcrum above described coarse regulation rotation axis and the whole rotation axis of accurate adjustment is hemisphere face body.
The present invention, compared with existing accurate displacement device, possesses following advantage:
(1) structure is simple, uses, easy to maintenance, does not need special training, can grasp its using method.
(2) less demanding for environment residing for micrometric displacement, can directly apply to production scene.
(3) easily manufactured, low processing cost.This device is for material, and machining precision and process equipment etc. do not have harsh requirement.Common mechanical manufacturing firm can the manufacture of complete cost apparatus, can directly transform on original gearshift basis simultaneously.
Can multistage-combination use be carried out, greatly improve the mobile accuracy of micrometric displacement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1 is lever, and 2 is coarse adjustment rotation axis fulcrum, and 3 is summit, and 4 is accurate adjustment rotation axis fulcrum, and 5 is coarse adjustment knob, and 6 is accurate adjustment knob, and 7 is leg.
Concrete embodiment
As shown in the figure, comprise 1 lever, 2 coarse adjustment rotation axis fulcrums, 3 summits, 4 accurate adjustment rotation axis fulcrums, 5 coarse adjustment knobs, 6 accurate adjustment knobs, 7 legs.Its specific works mode is as follows:
(1) turn left side coarse adjustment knob, its rotation axis radially moves, and motoricity in lever, drives lever summit to move by ball-type point action.Now the movable point of fixity of lever is at the position of the fulcrum of the whole knob of accurate adjustment.The displacement on summit is substantially equal to the displacement of coarse regulation knob fulcrum.
(2) when moving to roughly after desired location, stop the movement of coarse regulation knob, now this rotation axis will stop at fixed position.
(3) the whole knob of accurate adjustment on the right of turn, its rotation axis radially moves, and motoricity in lever, drives lever summit to move by ball-type point action.Now the movable point of fixity of lever is at the position of the fulcrum of coarse regulation knob.The displacement on summit will equal N/mono-of the whole knob displacement of accurate adjustment.
