Abstract
The utility model discloses a novel reading microscope cross-hair orientator constituted by glass sheets, a wedge seat, an adjusting rod, a top rod, and a pedestal. An upper glass sheet and a lower glass sheet can be used to form a wedge, and the monochromatic light can be reflected from the upper parts of the glass sheets to the upper glass sheet and the lower glass sheet with the help of a reflector. A clear wedge interference image can be adjusted to be displayed in the reading microscope, and the adjusting rod can be used to adjust the included angle of the wedge, and therefore the thickness and the density of the interference fringe can be changed. The fine tuning of the direction of the interference fringe can be realized by a horizontal screw and a spring, and a rotating wheel of the reading microscope can be adjusted, and the motion direction of the cross-hair intersecting point can be observed, and then the motion direction of the cross-hair intersecting point is superposed with the straight interference fringe, and the eyepiece sleeve of the reading microscope is rotated, and therefore the horizontal line of the cross hair is superposed with the straight interference fringe, and the vertical line of the cross hair is vertical to the measuring motion direction.
Description
Technical field
This patent relates to the structural design of the interference image parameter measurement reading microscope crosshair used orientors such as Newton ring and splitter, the generation device that particularly relates to the parallel thin straight line of reading microscope crosshair orientor, for the instrument adjusting operation before the interference image parameter measurements such as Newton ring and splitter.
Background technology
When measuring circle diameter with parallel rectilineal interval with reading microscope, first require to regulate the vertical line of crosshair perpendicular to measuring direction of motion, and this adjusting has been estimated with operator, its error is very large, and result causes measuring result error very large.Patent 201110068438.X has designed a kind of reading microscope crosshair orientor, on one flat plate, process one group of parallel lines, first from reading microscope, find these parallel lines, then regulate orientor and reading microscope, the direction of motion of the crosshair point of crossing of reading microscope is overlapped or parallel with in orientor parallel lines a certain, finally rotate the eyepiece stalk of reading microscope, the horizontal line of crosshair is overlapped or parallel rear fixed eyepiece cylinder with this straight line in orientor, so just guaranteed that the vertical line of crosshair is perpendicular to the measurement direction of motion of reading microscope, also just avoided measuring the caused error of direction of motion because crosshair is not orthogonal to.But, no matter how thin the parallel lines of making by modes such as machining or electromachining is, in reading microscope, seem all very thick, bring very large difficulty to and the coincidence of certain straight line in orientor parallel lines or parallel operation of the direction of motion of crosshair point of crossing, if the movement locus of reading microscope crosshair point of crossing is between two adjacent grooves, can only move orientor pedestal perpendicular to crosshair point of crossing moving direction just can make the movement locus of point of crossing overlap with a groove, operator can not guarantee this " vertically " motion at all, can only repeatedly adjust, or the movement locus of range estimation crosshair point of crossing is parallel with a nearest groove just, this is the accurate orientation that is unfavorable for crosshair.
Summary of the invention
In order to overcome orientor parallel lines, in reading microscope visual field, seem too slightly to crosshair point of crossing movement locus, to overlap or the difficulty that operation repetitive causes and the operating difficulties that moves crosshair orientor perpendicular to crosshair point of crossing movement locus, this patent has designed a kind of Novel reading microscope crosshair orientor, utilize splitter to interfere and produce the entity straight line that straight parallel striped replaces actual processing, can obtain desirable effect.
Novel reading microscope crosshair orientor described in this patent is mainly by slide, splitter seat, adjuster bar, push rod and base form, lower slide is placed on the bottom of slide groove, upper slide left end is in lower slide upper left, right-hand member is on push rod, splitter seat is on base, adjuster bar is fixed in the adjuster bar groove of splitter seat, the right-hand member of adjuster bar is through in the rectangular opening of push rod, left end is connected in set screw, spacing by stop nut, set screw bottom is screwed in base screw, in the arc of rotation of top in splitter seat left end, one end of spring is in the spring eye of base, the side of other end contact splitter seat, horizontal screw is screwed in the screw hole of base, the another side of horizontal screw end contact splitter seat.In the measurement of the interference image parameters such as Newton ring and splitter, by reflective mirror, monochromatic light is reflexed to upper and lower slide from slide top, in reading microscope, adjust splitter interference image clearly, rotating base, make interference fringe be parallel to measurement direction of motion, rotate the rotor wheel of reading microscope, observe the direction of motion of crosshair point of crossing, the horizontal screw of adjusting makes splitter seat rotate in the horizontal direction around set screw by the arc of rotation of left end, can make interference fringe be parallel to the movement locus of crosshair point of crossing, slowly rotate again set screw, by adjuster bar, promoting slide push rod rises, slide right-hand member is slowly raise, interference fringe is tapered and becomes close, when crosshair point of crossing overlaps with certain interference fringe, so repeatedly slowly rotate set screw and horizontal screw, until the movement locus of crosshair point of crossing and certain interference vertical bar line overlap completely.Unclamp the lock-screw of reading microscope eyepiece stalk, rotate eyepiece stalk crosshair horizontal line is overlapped with this interference vertical bar line, crosshair vertical line is at this moment just perpendicular to the measurement direction of motion of reading microscope.Directly rotating base 90 is spent, allow interference fringe overlap with crosshair vertical line, rotating set screw reduces slide right-hand member, interference fringe spacing strengthens, just can measure the spacing of interference fringe exactly, remove reading microscope crosshair orientor, change newton ' s ring device, adjust the interference image of Newton ring, just can measure the diameter of annulus by crosshair vertical line and the tangent mode of interference image annulus.
Because the extremely small variation of rising or decline of upper slide right-hand member also can cause the acute variation of interference fringe, so be adjuster bar and upper slide push rod coupling part length 2 to 10 times with the length of set screw coupling part in adjuster bar, be that set screw is revolved and turned around, upper slide push rod 1/10th to 1/2nd of the pitch that only rises, so just be conducive to the adjusting of splitter corner dimension, be namely conducive to the adjusting of interference fringe thickness density.
Novel reading microscope crosshair orientor of the present invention utilizes splitter interference fringe because the change of splitter angle is large, to become the close feature attenuating, movement locus and an interference vertical bar line that can be adjusted to crosshair point of crossing overlap completely, reduced to greatest extent the measuring error of parallel lines spacing and circle diameter, meanwhile, go back the relation of thickness density and the splitter corner dimension of observable splitter interference fringe.
