Abstract
In order to enable extremely accurate length dimensions of working gauges, a method and measuring system is provided which includes both special standard gauge blocks and special working gauge members, as well as an associated specialized measuring device by which a working gauge may be produced through a simple length adjustment of two mutually fixable displaceable elements. The adjustment is effected in the measuring device by comparison with the dimension of a pre-measured standard gauge block. The gauge blocks and working gauges may be similarly shaped and include, for example, a cylindrical body and a measurement defining pin projecting therefrom, thereby resulting in an inexpensive manufacturing of the gauge blocks and an easy adjustability of the working gauges.
Claims9
A method of preparing working gauges having a precision of 1 .mu.m using at least one gauge unit and a measuring device for enabling a comparative measuring of said at least one gauge unit and said working gauge during said preparation thereof, the method comprising:
- providing said working gauge including a longitudinally displaceable element;
- displacing said displaceable element by said comparative measuring into a position projecting from said working gauge such that a distance measurement between one end of said working gauge and a free end of said projecting displaceable element corresponds to a predetermined desired master measure;
- and
- fixing said displaceable elemet to said working gauge.
A system for the preparation of working gauges with a precision of 1 .mu.m, the system comprising:
- at least one gauge unit;
- a measuring device for comparative measuring of said gauge unit and said working gauge during said preparation thereof;
- a platform means for carrying the at least one gauge unit;
- means for adjusting a spacing between said platform means and an actuator member of a short distance measuring instrument;
- working gauges of different sizes, each of said working gauges including a displaceable element which is fixedly displaceable in a longitudinal direction, said working gauges being adapted to be individually inserted in said measuring device replacing said at least one gauge unit in such a manner that said displaceable element is adjustable to assume a position projecting from said inserted working gauge so as to define a desired master length based on engagement with said actuator element of said associated measuring instrument;
- and
- means for releasably fixing said displaceable element to said inserted working gauge.
