Abstract

The utility model relates to a center hole measuring tool which comprises a support and a dial indicator. The center hole measuring tool is characterized in that a header of the dial indicator is in threaded connection with a measuring bar, wherein the other end of the measuring bar is in threaded connection with a spherical probe; an elastic sleeve is arranged in a mounting hole of the support, and the header of the dial indicator is inserted into the elastic sleeve and fastened to the support through a tightening screw. The center hole measuring tool is simple in structure, easy to manufacture and low in cost; whether a taper hole of a part is qualified can be judged directly according to the indicated value of the dial indicator as long as the spherical probe is arranged in the taper hole of the part, so that detection accuracy and repeatability are high, and detection efficiency and precision are improved; center holes with different specifications can be detected as long as corresponding spherical probes are mounted to replace the spherical probe, so that the center hole measuring tool is high in economical efficiency.

Description

A kind of center pit is measured measurer
Technical field
The utility model relates to a kind of measurer, is specifically related to a kind of center pit and measures measurer.
Background technology
At mechanical processing industry, need the product of centering to be seen everywhere, particularly axial workpiece.Center pit is the important benchmark of axial workpiece, and car, cylindrical grinding are all located by center pit, and the degree of depth of center pit and tapering are to guarantee centering accurately, is also to guarantee that top tip and workpiece can not collided again and the important parameter of part post-production quality.Adopt aperture and the depth of center hole size of slide calliper rule amount center pit simple and convenient, but the measurement of this method is time-consuming, precision is low, poor repeatability, the crudy of part is unstable.
Summary of the invention
The purpose of this utility model is the shortcoming that will overcome above-mentioned technology, and a kind of simple in structure, low cost of manufacture, easy to use is provided, and high, the reproducible center pit of measuring accuracy is measured measurer.
Center pit of the present utility model is measured measurer, comprises bearing and dial gauge, it is characterized in that: the sounding rod that has been threaded in the gauge outfit of described dial gauge, and the other end of sounding rod is connected with spheric probe; In the mounting hole of described bearing, be built-in with resilient sleeve, the gauge outfit of dial gauge is inserted in resilient sleeve, by clamp-screw, is fixed tightly on bearing.
In order better to realize above-mentioned purpose:
Described sounding rod with spheric probe by being threaded.
Center pit of the present utility model is measured measurer, and expense simple in structure, easy to manufacture is low, only spheric probe need be placed in to the bellmouth of part, according to the indicated value of dial gauge, just can directly judge that whether part bellmouth is qualified, detection accuracy and reproducible, has improved detection efficiency and precision; Center pit for different size only need be changed corresponding spheric probe, good economy performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is embodiment schematic diagram of the present utility model.
In figure: 1, bearing, 2, resilient sleeve, 3, dial gauge, 4, gauge outfit, 5, clamp-screw, 6, sounding rod, 7, spheric probe, 8, part.
Embodiment
Center pit of the present utility model is measured measurer, comprises bearing 1 and dial gauge 3.The sounding rod 6 that has been threaded in the gauge outfit 4 of dial gauge 3, the other end of sounding rod 6 spheric probe 7 that has been threaded.In the mounting hole of bearing 1, be built-in with resilient sleeve 2, the gauge outfit 4 of dial gauge 3 is inserted in resilient sleeve 2, by clamp-screw 5, is fixed tightly on bearing 1.
During use, the spheric probe of measurer 7 is placed in to the bellmouth of part 8, according to the reading of dial gauge 3, just can judges that whether the bellmouth of part 8 is qualified.For the bellmouth of different size, only need to change corresponding spheric probe 7.
