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
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.
