Embodiment:

As shown in Figure 1, this instrument is fixed on the base 4 by footing 20, base for supporting 4, switch 2, lamp supply socket 3, illuminating lamp 10, and digital display case 9 usefulness support bars are fixed on the base 4 simultaneously.Backer 5 is fixed on base 4 workplaces, and V-block 6 relies on mountain 5 by the jail, and measured piece 7 places on the V-block 6, and Z is fixed on Z to handwheel 12, Z on slide plate 11 to grating sensor 15; Eyepiece 13, microscope 14, microscope scale 16, object lens 18 are formed the microscope group, are fixed on the Nicroscopium 8, and Nicroscopium 8 is fixed on Z on slide plate 11, focusing handwheel 17 and the interlock of microscope group tooth bar; Z to mobile handwheel 12 drive the whole group of microscopes do Z to mobile focusing, Z to the slide plate 11 amendable X that are fixed on slide plate 1, X is connected with base 4 to slide plate 1 usefulness line slideway, by X to mobile handwheel 21 rotating bands action X to move, be fixed on the X of X on slide plate 1 simultaneously and carry out displacement acquisition to grating sensor 19, last digital display case 9 shows measurement result.

Microscope is made up of object lens 18, eyepiece 13, graticule and scale 16, wherein scale 16 and graticule interlock and when " 0 " of " 0 " of scale line and scale vernier when line aligns, " ten " word line in the graticule is parallel with worktable respectively and vertical, and this moment, microscope was in normal operating conditions.If the scale vernier is walked about, only need rotate counterclockwise scale vernier (there is a location screw at scale vernier rear) before using, regulating head when screw and zero-bit contacts, the degree of blocking mark of playing, " 0 " line of scale is gone to " 0 " line with the scale vernier to agent, graticule " ten " word line just is in " 0 " position state again.Microscope gets final product operate as normal.

Microscope 14 moves X by X to mobile handwheel 21 and moves Z to slide plate 1, Z to mobile handwheel 12 and do horizontal, vertical and focusing handwheel 17 is focused to slide plate 11.Vee-block 6 has seven kinds, is used for placing measured piece 7.Vee-block 6 can be selected to use or combination stack use according to the size of measured piece 7 external diameters.Accurate grating sensor is equipped with in side horizontal, vertical guide rail, by can directly showing measurement data with being connected of digital display case 9.The area in base 4 the place aheads nearly 2/3rds is a workbench, the place ahead of worktable and right-hand horizontal stroke, vertical backer 5 be housed respectively, according to different detection requirements, vee-block 6 can lean on the jail with backer 5, measured piece 7 is in and microscope 14 parallel or plumbnesss, and instrument also is furnished with three kinds of mohs bush and a dial holder.

Principle of work: this instrument is based on the principle of measurement of coordinates, is with microscope 14 aimings and scanning measured piece 7, carries out linear measure longimetry by the mode of grating sensor 19 and digital display case 9 demonstration numerical value; Rotate the scale 16 that links with the microscope graticule, carry out measurement of angle by the relative position of observing scale 16 and scale vernier.

Operation and measurement explanation:

As shown in Figure 2, plug lamp supply socket 3, open switch 2 measured piece 7 is placed on the vee-block 6, vee-block has seven kinds, can select for use vee-block to be used in combination according to the different external diameter of measured piece, and movable illumination device 10 reaches lighting requirement.According to concrete detection requirement, vee-block 6 can compress or place the optional position by the jail and with pressing plate with level or the vertical backer 5 on the worktable; Microscope is done about directions X and Z direction vertical moving, focusing before and after the Y direction is done, the tested part of measured piece 7 is imaged on the graticule in the microscope, by the one side of a line wherein of cross curve on the graticule, usually select horizontal line during measuring height for use, select perpendicular line when measuring width for use, the initiation feature point or the line of aiming measured piece; With the digital display reset, scan another feature point or the line that moves to measured piece through microscope, the numerical value that digital display case 9 shows is the length measurements of measured piece 7.

As shown in Figure 3, Figure 4, also be carved with the circle of one group of different-diameter on the graticule, when corresponding, can directly overlap inspection with a certain circle on the graticule as the diameter of measured piece 7.

By on cross central point aiming measured piece 7 certain lines (this line is the characteristic curve of tested angle) on the graticule a bit, clockwise rotate scale, this moment, graticule and scale 16 rotated synchronously, and the scale vernier is motionless, when a certain line of graticule cross curve (specifically select for use that line convenient by gauger oneself decision according to measuring) and tested lines are overlapping, observe scale and scale vernier, can directly obtain the measured value of angle.
