Description
The utility model belongs to optical gauge, is widely used in precision optical machinery manufacturing and optical instrument adjustment.
At present employed optical gauge has that the optical instrument factory, Shanghai produces in optical instrument adjustment work 1 " autocollimation micrometer parallel light tube, Britain's black square-Watts company produce 0.2 " autocollimation micrometer parallel light tube and 0.2 " the JZC type autocollimation micrometer parallel light tube that two-way autocollimation micrometer parallel light tube and first optical instrument factory, Changchun produce, square tube preset lens etc.
Autocollimatic as if the black bright background of crosshair in 1 " and 0.2 " autocollimation micrometer parallel light tube, the outgoing graticule throws light in the imaging place first time, and visual brightness reduces greatly, but the outgoing axle is coaxial with the optical axis, only is applicable to the occasion of single face strong reflection face.
Though JZC type autocollimation micrometer parallel light tube is bright crosshair dark background, the outgoing axle is coaxial with the optical axis, but outgoing graticule illumination is also in the imaging place first time, and the scope of application than preceding two kinds of light pipes more greatly, but image planes and optical axis have inclination slightly, and the visualization image planes are unreal.
0.2 " the outgoing axle of two-way autocollimation micrometer parallel light tube and optical axis disalignment can not be used in some occasion.
The optical axis of above-mentioned all autocollimation micrometer parallel light tube and the axis of tool housing all do not have strict relationship, thus can not satisfy some requirement in adjusting of some optical instrument, as require the optical axis parallel with the earth, or require the crosshair vertical line directly in the earth.Though the square tube preset lens can satisfy these requirements, but do not possess the function of autocollimation micrometer parallel light tube, can't work independently yet.
The purpose of this utility model provides a kind of multi-functional autocollimation micrometer parallel light tube, not only has the function of general micrometer parallel light tube, and the function of square tube preset lens is arranged again simultaneously.
The utility model is that the two structure of autocollimation micrometer parallel light tube and square tube preset lens is combined together, and spectroscope, visual graticule, outgoing graticule is glued together, makes the outgoing axle coaxial with optical axis strictness.An imaging type is adopted in imaging, and the outgoing graticule adopts bright crosshair dark background type, thereby makes brightness height, the contrast of autocollimatic elephant big.
Optical principle of the present utility model is seen Fig. 1.Object lens 2 and negative lens 3 are formed the principal goods mirror, and its back focus is positioned on the delineation face of visual graticule 5, also is positioned on the bright crosshair plane of outgoing graticule 8.The outgoing axle overlaps with the optical axis, bulb 10 process condensers 9 illuminate the bright crosshair on the outgoing graticule 8, the light of bright crosshair is through spectroscope 4, negative lens 3,2 one-tenth parallel beam outgoing of object lens are reflected after on the delineation face of object lens 2, negative lens 3, spectroscope 4 arrival graticules 5 through catoptron 1 again.If the bright crosshair picture that the reflecting surface of catoptron 1 perpendicular to emergent ray, then reflects just in time drops on the center of reticule in the visual graticule 5.If the reflecting surface of catoptron 1 is not orthogonal to emergent ray, the bright crosshair picture that then reflects just departs from the center of reticule in the visual graticule 5, and deviation value can be read by the observation of eyepiece 7 and the micrometer travel mechanism of micrometer graticule 6 by eyes.Whole optical system is contained in the square shell of instrument, and the optical axis is parallel to the long limit of instrument square shell, and crosshair is parallel to the minor face of instrument square shell.The square shell of instrument is contained on the aligning elevation gear again.Because luffing mechanism is dismountable, only stays the square shell benchmark, also can satisfy the needs of some application scenario.If mix some annexes, as multiaspect reflection rib body, 90 ° of catoptrons, stride bubble etc., can make its function comparatively complete.This utility model has been widely used in the field in optical measurement detection, optical instrument adjustment, precision optical machinery manufacturing.
Owing to select for use outgoing axle and optical axis coaxial-type, range of application then of the present utility model to take on the working range of the autocollimation micrometer parallel light tube of non-coaxial-type.Because the outgoing graticule is selected bright crosshair dark background and Polaroid type for use, range of application of the present utility model has taken on the working range of the autocollimation micrometer parallel light tube of other type (secondary imaging and the dark bright background of crosshair).Because the structural principle of the utility model collection autocollimation micrometer parallel light tube and the structural principle of square tube preset lens are one, make its function again, a horizontal optical axis and crosshair pedal line can be provided again simultaneously with autocollimation micrometer parallel light tube.Thereby the utility model is multiple functional, applicable to the multiple measurement of optical instrument adjustment.The utility model wildcard is put 90 ° of catoptrons, regular polygonal prism mirror, is striden annexes such as bubble, can finish following surveying work: the 1. straight line degree measurement of guide rail; 2. the measurement of planeness of massive plate; 3. revolving shaft rocks measurement; 4. the measurement of regular polygonal prism body actual corners value; 5. the measurement of code-disc angular error; 6. 90 °, the angle error of 45 reflection part are measured; 7. comparative method for measuring angle part angle error; 8. to the horizontal optical axis and crosshair pedal line etc. are provided in some optical instrument adjustment.
Embodiment: the utility model is mainly by four most of compositions.First forms the principal goods mirror element by object lens and negative lens, and its shell is done squarely.Second portion is formed the micrometer parts by reading drum, visual graticule, micrometer graticule, spectroscope, outgoing graticule, eyepiece.Third part is the illuminator lamp head, and the outgoing graticule is used for throwing light on.The 4th part is that pitching adjusting gear principal goods mirror element, micrometer parts, lamp holder three's combination promptly becomes autocollimation micrometer parallel light tube.Because principal goods mirror shell is done squarely, to guarantee that the optical axis is parallel to the long limit of square shell during the optics assembling, crosshair is parallel to the minor face of square shell, and then the utility model becomes a square tube preset lens again.Elevation mount can be loaded onto or be removed according to the requirement of using.
The utility model should be noted the following aspects in manufacture process:
1. guarantee the accurate focal length value of principal goods mirror, the micrometer leading screw is selected for use the pitch of 0.5mm, one week of reading drum is carved 150 lattice, and every lattice represent 0.2 ", a week is 30 ".The micrometer mode adopts a micrometer leading screw to measure the amount of two orthogonal directions simultaneously, the exact value of micrometer leading screw pitch can by repair cut repairing between object lens and the negative lens cut the circle reach.
