Description
Technical field:
The utility model is relevant with the material deformation measurement mechanism, and is especially relevant with the angular deformation in the material twisting test sample marking distance.
Background technology:
In material twisting test field, require accurately to measure the angular deformation in the material twisting test sample marking distance, in the hope of the modulus of torsion of drawing materials and disproportional stress etc., and traditional test method and survey instrument can't be accomplished.
The content of utility model:
The purpose of this utility model provides a kind of torsion angle deformeter, can accurately measure the angle change table in the material twisting test sample marking distance.
The utility model is achieved in that
The utility model torsion angle deformeter, form by scale holder 1, dial gauge holder 2 and scale, each end and scale 13 that scale holder 1 and dial gauge holder 2 are separately fixed at tested sample 3 are connected the parallel axes of the axis of scale 13 and tested sample 3.
The axis of scale 13 and tested sample 3 is positioned on the same water surface.
Scale holder 1 has horizontal ruler frame 11, the one end is connected with fastening bolt 25 and scale 13, the scale holder other end is hinged by pivot pin 14 and pressing plate 12, and pressing plate 12 has the half slot of symmetry to cooperate with tested sample 3 with scale frame 11 joint faces, and fastening bolt 25 is arranged.
One end of the dial framework 21 of dial gauge holder 2 is hinged by bearing pin 24 and pressing plate 23, both joint faces have the half slot of symmetry to cooperate with tested sample 3, fastening bolt 25 is arranged, the lower horizontal plane of the other end of dial framework 21 and scale 13 are connected by fastening bolt 25, dial gauge 22 is installed, on the surface level that is projected in scale 13 of dial gauge measuring contacts above the dial framework.
The utility model torsion angle deformeter is made up of the scale stiff end and the dial gauge stiff end that are installed on the tested sample, by measuring the two ends relative displacement, can ask for the interior relative deformation angle of two ends gauge length through simple triangulation calculation again when sample reverses.Simple in structure, light, low cost of manufacture, easy to use.
Description of drawings:
Fig. 1 is a front view of the present utility model.
Fig. 2 is an A-A view of the present utility model.
Fig. 3 is a B-B view of the present utility model.
Embodiment:
With reference to Fig. 1, Fig. 2, the utility model torsion angle deformeter is made up of the scale holder 1 and the dial gauge holder 2 that are installed on the tested sample 3.Scale holder 1 is installed on the tested sample 3 by pivot pin 14 and fastening bolt 25 by scale frame 11 and pressing plate 12, and scale 13 is installed on the scale frame 11.Dial gauge holder 2 is installed on the tested sample 3 by pivot pin 14 and fastening bolt 25 by dial framework 21 and pressing plate 23, and dial gauge 22 is installed on the dial framework 21.
When tested sample 3 is subjected to twisting resistance, can produce distortion along the circumferential direction, at this moment scale holder 1 and dial gauge holder 2 will produce relative angular displacement α around the sample center of circle, and the displacement that this moment, dial gauge recorded is H.
Pass through formula: α=arctgH/L can try to achieve and reverse the change angle.
L is the distance between the axis of scale axis and sample.
If adopt band external tapping electronics dial gauge, the data that record directly can be transferred to computing machine, parameters such as modulus of torsion that directly calculates sample material by relevant mechanics formula and sample parameter and disproportional stress.
