Summary of the invention
It is an object of the invention to provide the high step gauge of a kind of simple in construction, precision and assemble method thereof, the error produced during for reducing calibration.
For achieving the above object, present invention employs following technical scheme:
A kind of step gauge, including matrix, the a plurality of gauge blocks being closely embedded in matrix and axial direction positioning device, it is more than two of which that the one end of spaced selected gauge block exposes from matrix one side, more than two of which on the working face of selected gauge block, it is equipped with an anchor point, described axial direction positioning device includes the locating piece being arranged at described matrix two ends, it is provided with a basic point on these two locating pieces, these two basic points connect formation one reference axis, described anchor point is distributed in this reference axis, between the most any two pieces of gauge blocks, the distance of instruction is the distance between the anchor point on these two pieces of gauge blocks.
Further, described locating piece is spherical locating piece, and the centre of sphere of described spherical locating piece is basic point.
As one of scheme that can implement, located piece of base of described spherical locating piece is fixedly connected on described matrix both ends.
As more one of preferred embodiment, described locating piece base is additionally provided with the micromatic setting for adjusting spherical locating piece.
A kind of assemble method of step gauge, including:
One matrix is provided, and in described matrix, is closely embedded a plurality of gauge block, and make the one end of the spaced selected gauge block of more than two of which expose from matrix one side, and select in two or more and on the working face of gauge block, be respectively provided with an anchor point,
And, it is respectively provided with a positioning block at described matrix two ends, and it is respectively provided with a basic point on these two locating pieces, connect with these two basic points again and form a reference axis, and making described anchor point be distributed in this reference axis, between the most any two pieces of gauge blocks, the distance of instruction is the distance between the anchor point on these two pieces of gauge blocks.
Further, described locating piece is spherical locating piece, and the centre of sphere of described spherical locating piece is basic point.
Further, located piece of base of described spherical locating piece is fixedly connected on described matrix both ends.
As more one of preferred embodiment, described locating piece base is additionally provided with the micromatic setting for adjusting spherical locating piece.
The present invention forms virtual reference axis by the basic point arranged on two locating pieces, this reference axis is crossed to form anchor point with the working face of each gauge block, and the displacement of step gage obtains with the axial distance by the anchor point examining working face by measuring the anchor point on zero point working face；Even if being tilted by inspection working face or zero point working face, but owing to the position of anchor point is basically unchanged, therefore its deviation will not be very big, it is thus possible to overcome the error that depth of parallelism difference causes, it is achieved accurate calibration.
Compared with prior art, the beneficial effects of the present invention is: be not only simple in structure, low cost, and calibration accuracy is high, it overcomes, by axially location, the error produced because of the depth of parallelism, it is achieved accurate calibration.
