Gauge Distance Display for Tensile Test Specimen

摘要

The subject innovation relates to a device for displaying the gauge length on the test piece to the stretching of the specimen during a tensile test of the material for the measurement provided.; Apparatus according to the present invention is the nureugae 5 and, the nureugae 5 is fixedly coupled in the vertical direction on both sides and a pair of identical holding (6) having a gauge display part 2 is of the cone on the lower end of, the opposite sides the moving hole 10 is the pillar (6) is provided inserted to be movable in a limited range of distances up and down the lower portion of the gauge visible to the test piece (3) is raised on a support that supports 14 and 15 are formed which is characterized in a framework (9), a configuration including a spring 8 is provided between said elastic nureugae 5 and the framework (9).; The apparatus of the present design by the simple configuration, the surface of the gauge bar to the desired image of the test piece (3) in the form of a round bar at all times, and provides an effect that can even talk to the accuracy of the measurements are correct.
