Description
Technical Field
The utility model belongs to the field of measuring instruments, and particularly relates to a length measuring standard step gauge.
Background
The step gauge is a precise multi-size length object standard, has precise series step size, external size and internal size, and is used for detecting precise measuring instrument measuring tools and precise numerical control machines, such as three-coordinate measuring machines and precise length measuring machines, precise micrometers, calipers and calipers, precise numerical control machines and the like, instead of a precise measuring block with single-value size. Therefore, the step gauge is required to have high accuracy of the step size, the outer size and the inner size, and high accuracy of parallelism and dimensional stability. At present, the existing step gauge mainly has three structural forms: the assembled type with the cushion block, the assembled type without the cushion block and the integral type. The cushion block assembled step gauge has the fatal defects of poor dimensional stability, unsuitability for calibrating high-precision large-range three-coordinate measuring machines, precise numerical control machines and the like, and the base is too heavy to be carried, installed and used conveniently; the annual stability of the size of the cushion-block-free assembled step gauge is better than that of the cushion block assembled step gauge, the cushion-block-free assembled step gauge is suitable for calibrating a high-precision large-range numerical control machine tool and a three-coordinate measuring machine, but the parallelism of a measuring surface is poor, the base of the cushion-block-free assembled step gauge is lighter than that of the cushion block assembled step gauge, but still is heavy and inconvenient to install and use, and the assembly and debugging are difficult and the measurement of the inlet and the outlet of a measuring head during use is inconvenient because the standard cylindrical rod of the cushion-block assembled step gauge is embedded in the rectangular groove of the axial lead of the base; the parallelism of the measuring surface of the integral step gauge is high, the step size can be used according to the actual size of calibration, a base and a cushion block are not arranged, the weight is reduced by about 2/3 compared with the two assembled step gauges, the annual stability of the size is high, and the step gauge is suitable for calibrating a high-precision large-range precise three-coordinate measuring machine, a precise length measuring machine and a precise numerical control machine tool and is convenient to carry to a field for use. However, the traditional step gauge has a large number of measuring surfaces and is difficult to machine and manufacture.

In order to solve the technical problems, the utility model adopts the technical scheme that: the measuring device is in the shape of a long rectangular block, two end faces of the long rectangular block are mutually parallel measuring working faces, a plurality of rectangular saw teeth are formed above the long rectangular block, one of the two end faces is a starting datum plane A face, the face, opposite to the starting datum plane A face, of each rectangular saw tooth is a measuring face, and the distance from each measuring face to the starting datum plane A face is a series of external dimensionsL i(ii) a The opposite surface of the sawtooth on the other end surface of the two end surfaces is a starting reference surface B surface, and the distance from each measuring surface to the starting reference surface B surface is the series inner dimensionK i(ii) a The measuring surface adjacent to the A surface of the starting datum plane is a C surface of the starting datum plane, and the distance from each measuring surface to the C surface of the starting datum plane is a series of step sizesP i。
In the above technical solution, a more specific solution is: the distance from the measuring surface with the shortest distance to the A surface of the initial reference surface is the outer dimensionL 1The distance from the second short measuring plane to the A plane of the initial reference plane is the outer dimensionL 2By analogy, the distance from the measuring plane with the longest distance to the A plane of the starting datum plane is the outer dimensionL n。

Due to the adoption of the technical scheme, compared with the prior art, the method has the following beneficial effects:
because the two end faces of the long rectangular block of the step gauge are parallel measuring working faces, a plurality of rectangular saw teeth are formed above the long rectangular block, one side face of each saw tooth can be a measuring face, the other side face of each saw tooth is a non-measuring face, the distance between each measuring face and the three initial reference faces forms three dimensional requirements of series step sizes, outer sizes and inner sizes required by the step gauge, the number of the measuring faces is reduced by half compared with the number of the measuring faces of the traditional step gauge, the processing and manufacturing difficulty is reduced, and the processing and manufacturing cost is reduced.
