Embodiment
Following for by reference to the accompanying drawings apparatus of the present invention being elaborated.
Fig. 1 is structure principle chart of the present invention.Fig. 2 is the sectional view of Fig. 1 of the present invention.Can find out from Fig. 1 ~ 2, the electronic plug gauge based on flexible hinge of the present invention, for the inside diameter measurement of hole type parts.Wherein matrix 10 is a lever, the integrally formed frock of flexible hinge, matrix 10 by screw fastening on positioning seat 6.Bulb II is fixed on lever lower end, and limit shaft 15 is fixed in the through hole of matrix 10 lower ends, becomes " ten " sub-shape with matrix, and its position is adjustable, fastening by screw 12.Bulb III, bulb IV are fixed on limit shaft 15, are fixed on another bulb I on matrix and the bulb II conllinear of lever lower end, and these four bulb symmetries, coplanar distribution, fix a pad 14 under each bulb, and its thickness as required disposable repair is good.Chuck 3 is fixed on matrix 10 by screw 4, inductance displacement sensor 2 is through chuck, lock-screw 1 is locked inductance displacement sensor 2, and the face that the locating surface of positioning seat 6 forms with bulb I, II, III, IV is flat substantially parallel, and heat-insulating base 5 is fixed on the outside of positioning seat 6 by screw.Spacing ring 8 and stop screw 9 be all restriction lever around flexible hinge rotate distance with protection flexible hinge.The hand-held heat-insulating base 5 of operator can be pressed into workpiece by matrix 10, and bulb I withstands a side in hole, and bulb II rotates around flexible hinge with lever, inside dimension is transformed to the outside dimension of easy measurement, is measured and is shown by inductance displacement sensor 2.Bulb II equates to the distance of this fulcrum with inductance displacement sensor 2 to the distance of flexible hinge fulcrum, and the transmission of lever ratio is 1:1, and the radial distance that therefore bulb II rotates is accurately measured and shown by inductance displacement sensor 2..
The thickness of repair bulb III, bulb IV lower gasket 14, makes the summit line distance of bulb III, bulb IV be less than tested aperture 0.02mm left and right, bulb I, the large 0.1-0.2mm in the tested aperture of bulb II gap ratio.Regulate limit shaft 15 positions, in the time that bulb III, bulb IV are symmetrical along matrix, tighten the fixing limit shaft 15 of screw 12.
In measuring process, taking bulb I as fulcrum, maintain static bulb II fine motion, rotation or the translation scope of bulb III, bulb IV restriction matrix 10 in measured hole.Adjust when suitable when the thickness of pad, measurement mechanism is put into measured hole or ring gauge at every turn, measurement data changes and is less than 0.5 μ m, thereby directly draws aperture value, improves and measures efficiency and measuring repeatability.
Before measurement, described electronic plug gauge is put into the ring gauge identical with measured hole, the measuring staff of mobile inductance displacement sensor 2, the display reading of displacement transducer is tightened lock-screw 1 near 0 time, then electronic plug gauge is put into measured hole, delta data with respect to ring gauge just can directly be shown by inductance displacement sensor 2, thereby obtains the exact value of inside dimension.
Be understandable that, electronic plug gauge of the present invention also can be measured the groove width of equidimension, and those skilled in the art also can do other based on spirit of the present invention and change to apply in other respects, as long as it does not depart from technique effect of the present invention.These variations of doing according to spirit of the present invention all should be considered as in the present invention's scope required for protection.
