Abstract

The invention relates to a stress application mechanism in an apparatus for measuring the tiny shear strain of a material. The stress application mechanism includes a supporting frame and a compression dynamometer; the supporting frame is provided with two horizontal supporting rods arranged in parallel; the supporting frame is provided with an adjustment nut in a threaded connection manner; the compression dynamometer is arranged on the two supporting rods, one end of the compression dynamometer is connected with the inner end of the adjustment nut, and the other end of the compression dynamometer is provided with a thrust rod; and the other end of the thrust rod is in contact with one end of a deflector rod. The shear strain value can be directly measured in the invention, so the measurement precision is improved, and the mechanism has a simple structure, and is convenient to use.

Description

A kind of boosting mechanism measured in the small shear strain device of material
Technical field
The present invention relates to Experiments of Machanics instrument field, refer in particular to a kind of boosting mechanism measured in the small shear strain device of material.
Background technology
Existing measurement material small shear strain device gives by boosting mechanism the shearing stress that one, vertical bar is very little, drive sample to produce to reverse, observe the angle of reflected light skew and combine the shear strain that the shearing stress value applied calculates material, but the shearing stress applied needs manual going to measure, not only measure inconvenience, and easily cause measuring error, thus reduce measuring accuracy, for this reason, we have developed a kind of boosting mechanism measured in the small shear strain device of material, directly can go out shear strain value in side, thus improve measuring accuracy.
Summary of the invention
The present invention seeks to provide a kind of boosting mechanism measured in the small shear strain device of material to overcome the deficiencies in the prior art, directly can go out shear strain value in side, thus improve measuring accuracy.
For achieving the above object, the technical solution used in the present invention is: a kind of boosting mechanism measured in the small shear strain device of material, comprises bracing frame, compression dynamometer; Support frame as described above is provided with the support bar of two levels and parallel placement; Support frame as described above is provided with the setting nut be threaded; Described compression dynamometer is arranged on two support bars, and one end is connected with the inner of setting nut, and the other end is provided with distance rod; During work, the other end of described distance rod contacts with one end of driving lever.
Preferably, described setting nut is arranged between two support bars.
Preferably, the two ends of described support bar are fixed on bracing frame respectively by screw.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Boosting mechanism in the small shear strain device of measurement material of the present invention directly can go out shear strain value in side, thus improves measuring accuracy, and structure is simple, easy to use; Be convenient to teacher by experiment and on classroom, explain abstract shear strain knowledge point, concrete image more, make classmate more acceptant, improve learning efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of the boosting mechanism in the small shear strain device of measurement material of the present invention;
Wherein: 1, bracing frame; 2, driving lever; 3, screw; 4, support bar; 5, distance rod; 6, dynamometer is compressed; 7, setting nut.
Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing 1 is the boosting mechanism in the small shear strain device of measurement material of the present invention, comprises bracing frame 1, compression dynamometer 6; Support frame as described above 1 is provided with the support bar 4 of two levels and parallel placement; The two ends of described support bar 4 are fixed on bracing frame 1 respectively by screw 3, are convenient to maintain and replace; Support frame as described above 1 is provided with between two support bars 4 setting nut 7 be threaded; Described compression dynamometer 6 is arranged on two support bars 4, and one end is connected with the inner of setting nut 7, and make compression dynamometer 6 uniform force, the other end is provided with distance rod 5; During work, the other end of described distance rod 5 contacts with one end of driving lever 2.
During use: first rotate setting nut 7 and compression dynamometer 6 reading is made zero; At rotation setting nut 7, promote distance rod 5 drive driving lever 2 to rotate by compression dynamometer 6, shear strain value can directly read on compression dynamometer 6.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Boosting mechanism in the small shear strain device of measurement material of the present invention directly can go out shear strain value in side, thus improves measuring accuracy, and structure is simple, easy to use; Be convenient to teacher by experiment and on classroom, explain abstract shear strain knowledge point, concrete image more, make classmate more acceptant, improve learning efficiency.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
