Abstract
The invention discloses a bearing platform for an optical measurement mechanism, which comprises a first support and a second support; an eccentric shaft consisting of an eccentric body as well as a left rotary shaft and a right rotary shaft which are respectively arranged at the two ends of the eccentric shaft body is positioned between the first support and the second support; the left rotary shaft and the right rotary shaft are respectively embedded in through holes of the first support and the second support; the eccentric shaft body consists of a center shaft body and step shaft bodies arranged at the two ends of the center shaft body; a first inclined block and a second inclined block which are provided with inclined planes are respectively fixed at the inner sides of the first support and the second support and are positioned at the two sides of a linear guideway; through holes arranged at the upper ends of first and second leaf springs are respectively embedded in the step shaft bodies arranged at the two ends of the center shaft body; the lower ends of the first and second leaf springs are respectively positioned between the linear guideway and the first inclined block and between the guideway and the second inclined block; and two opposite bulged blocks are oppositely arranged on the lower ends of the first and second leaf springs. According to the bearing platform provided by the invention, the probability of an objective stage deviating from a center line and shocking is reduced, so that correcting measurement precision of optical equipment such as high-precision laser imager and the like is facilitated.
Description
Technical field
The present invention relates to a kind of optical measuring apparatus, be specifically related to a kind of carrying platform that is used for optical measurement mechanism.
Background technology
The prior art carrying platform; When jobbie moved on slide rail, the locking device of this carrying platform linked together object moving and slide rail often, produced bigger friction force; Thereby reach the purpose of locking; The method of its locking is that excentric shaft directly is pressed in the guide rail top, and the guide rail top is the main rubbing surface of object operation, and several shortcomings are arranged above directly being pressed in: the 1) rubbing surface of infringement guide rail; 2), make objective table itself produce the factors of instability because acting force and reacting force exist simultaneously, and under the effect of reacting force, objective table has up trend.Our high-precision laser imager particularly, measuring accuracy all is nano level, and a displacement is arranged a little, it is far that its measurement luminous point will drift about, and must proofread and correct again.
Summary of the invention
The object of the invention provides a kind of carrying platform that is used for optical measurement mechanism, and this carrying platform has reduced the probability of objective table off center line and vibrations, thereby the measuring accuracy that helps optical devices such as high-precision laser imager is proofreaied and correct.
For achieving the above object; The technical scheme that the present invention adopts is: a kind of carrying platform that is used for optical measurement mechanism; Comprise objective table, line slideway, be positioned at said line slideway both sides and be fixed in first, second support of said objective table lower surface; One excentric shaft be made up of eccentric body shaft, the left rotary shaft that is arranged at the eccentric body shaft two ends and right spindle is between first, second support, and this left rotary shaft, right spindle embed respectively in the through hole of said first, second support; Said eccentric body shaft is made up of center axis body and the step axis body that is positioned at axis body two ends, center; The diameter of this step axis body is less than the diameter of said center axis body; First, second italic piece with inclined-plane is individually fixed in said first, second support inboard and is positioned at said line slideway both sides; The through hole of first, second spring leaf upper end embeds respectively on the step axis body at axis body two ends, said center; First, second spring leaf lower end separately lays respectively between line slideway and first, second italic piece, and first, second spring leaf mutually is provided with protruding block in the bottom separately privately, and this first, second spring leaf protruding block separately is corresponding with first, second italic piece inclined-plane separately; When excentric shaft rotates, drive first, second spring leaf and move up and down, thereby make protruding block slide at said chamfered surface.
Further improvement project is following in the technique scheme:
1, in the such scheme, said step axis body is set with its this annulus of annulus between first, second spring leaf and first, second italic piece.
2, in the such scheme, the number of said line slideway is at least 2.
3, in the such scheme, said handle is fixed in the end face of left rotary shaft or right spindle through connecting link.
4, in the such scheme, said line slideway is circular line slideway.
5, in the such scheme, said protruding block is salient point or sheet asbestos.
6, in the such scheme, said first, second spring leaf material is a copper
Because the technique scheme utilization, the present invention compared with prior art has advantage and effect:
The present invention is used for the carrying platform of optical measurement mechanism, embraces the both sides of guide rail simultaneously with two spring leafs, makes the trend of disalignment be able to overcome; Secondly, because first, second spring leaf material is a copper, when holding guide rail tightly, little to the guide rail damage.Because two spring leafs are embraced the both sides of guide rail simultaneously, main supporting surface is held concurrently, and slipping plane---the upper surface of guide rail is not affected.So the not influence of measurement light to having mixed up has guaranteed the accurate of measurement, lower inclined plane can change the gap between inclined-plane and the guide rail in the adjustment, and the size in gap has determined to compress the size of strength under the identical situation of handle motion angle.The big snap-in force in gap is just little, and the little snap-in force in gap is just big, is the relation of inverse ratio between them.
