Description
Technical field
The present invention relates to a kind of instrument that detects apart from size, particularly a kind ofly detect on the part curved surface a certain cross section apart from the instrument apart from size between another parallel plane.
Background technology
The detection method of the size of adjusting the distance at present has and adopts as the general measurers such as vernier caliper, height gauge are directly measured, projector upslide shadow measurement is measured, coordinate measurement Law measurement on the three-dimensional gauge.When needs measure perpendicular to a certain axis and comprise take the circular arc of a certain radius-of-curvature SR around this axis turn round formed surface of revolution cut mutually formed section circular diameter as the cross-sectional distance of a certain diameter value φ d perpendicular between another plane of this axis apart from size P the time, since to measure a certain cross section on the part curved surface apart between another parallel plane apart from size, generally adopt aspect indirectly to determine measured section on the curved surface, be difficult to determine measuring basis, measuring error is very large; Particularly in process, can't satisfy 100% on-line measurement demand of production scene, efficient is lower, cost is higher.
Summary of the invention
In order to solve an above-mentioned difficult problem, the purpose of this invention is to provide a kind of can qualitatively judge out perpendicular to a certain axis and comprise take the circular arc of a certain radius-of-curvature SR around this axis turn round formed surface of revolution cut mutually formed section circular diameter as between another plane of cross-sectional distance of a certain diameter value φ d apart from size P qualified cubing whether, thereby realize detecting quickly and easily.This invention is easy to realize, simple to operate, the measurer cost is low, has solved the online demand that detects in production scene, and when the size that requires to adjust the distance is carried out 100% detection inefficient problem.
Cubing of the present invention, structure is integrated the two ends formula, left end is limes superiors gauge hole, right-hand member is smallest limit gauge hole, inside, middle part is measuring basis hole (1), and datum hole end face (3) is of a size of tested upper limit P apart from size P to the distance of limes superiors gauge hole end surface (2)
Max, datum hole end face (5) is of a size of tested smallest limit size P apart from size P to the distance of smallest limit gauge hole end surface (4)
MinThe value of the φ d at measured section place equates on the value of the aperture size φ D in measuring basis hole (1) and the part, directly determines measuring basis at surface of revolution with datum hole during measurement.
Turn round formed surface of revolution take the circular arc of a certain radius-of-curvature SR around this axis and cut mutually formed section circular diameter as between the cross section of a certain diameter value φ d and another plane during apart from size P when measuring perpendicular to a certain axis with cubing of the present invention and comprising, limes superiors gauge end with cubing is inserted in tested part from right to left first, make gauge because of till being subjected to stopping of part can not continue to move right, observe limes superiors gauge end face and tested transverse plane this moment along the interior situation that contacts of 360 ° one in axis week.As since on the surface of revolution on datum hole aperture and the tested part diameter be the circle of φ d contact and so that the measurement end face on the limes superiors gauge do not contact fully with tested transverse plane A on the part, judge this size overlength, as since on the surface of revolution on datum hole aperture and the tested part diameter be that the circle of φ d does not contact and so that the measurement end face on the limes superiors gauge contacts fully with tested transverse plane A on the part, judges that then this does not have overlength apart from size P;
Then, other end smallest limit gauge with cubing of the present invention detects by same method of operating again, as because the measurement end face on the smallest limit gauge contacts fully with tested transverse plane A, judges that this size P is ultrashort, such as not fully contact, judge that this does not have ultrashort apart from size P; When using the limit gauge passed examination, can only illustrate does not testedly have overlength apart from size P, also will check with the smallest limit gauge simultaneously, and during smallest limit gauge passed examination, can only illustrate does not testedly have ultrashort apart from size P.Only have when limes superiors gauge and the inspection of smallest limit gauge are all qualified: the measurement end face of limes superiors gauge contacts fully with tested transverse plane, the measurement end face of smallest limit gauge does not contact fully with tested transverse plane, could judge that tested is qualified apart from size P.
This detection method is owing to being directly to determine that with the datum hole on the cubing limit gauge of the present invention measuring basis has reduced measuring error on the part surface of revolution, and cubing is easy to realize, simple to operate, the measurer cost is low, be specially adapted to detect and require to carry out 100% situation when detecting online in the production scene.
