The clamping apparatus can be used in a high-precision pure shear test and a variable-angle shear test, and can simplify the test operation procedures. The hollow cavity of the stopper for holding the shear test sample is in close fit to the test sample, so that the test sample is in a plane stress state and the pure shear to the test sample is realized. The clamping apparatus can change the loading direction by arranging the shaft heads on different threaded holes. The entire apparatus is easy to realize volume test of the material properties.
Description
Technical field
The utility model relates to a kind of varied angle shear test anchor clamps, can carry out the mechanical test relevant with the material cutting performance easily.
Background technology
At present, general shearing test method is the thin wall cylinder torsional technique, and the hypothesis that this method is in plane stress state with test specimen can produce uniform pure shear stress state as theoretical foundation, but test unit, operation etc. are all very complicated, and strict to the selection of test material.Domestic research to the material cutting performance mainly is to adopt double V-shaped fluting shear test (HB7237-1995), this method is simple to operate, be applicable to most of materials, but to flexible material deformation perpendicular to the stress plane direction can appear, this will inevitably influence its measuring accuracy, and the loading angle of shear test is immutable.
The utility model content
For moulding, processing and the test unit that solves shear test measuring accuracy and test specimen, the contradiction between the Operating Complexity, the utility model provides a kind of varied angle shear test anchor clamps, it can not only carry out the pure shear test of degree of precision, and can operate by short form test, can also carry out the shear test of varied angle.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of varied angle shear test anchor clamps, two loading discs and shear test test specimen about comprising, loading disc middle part, the left and right sides is provided with groove, be respectively equipped with two limited blocks and test test specimen on the groove, limited block and test test specimen are provided with baffle plate, left and right sides loading disc symmetria bilateralis is provided with spindle nose, and spindle nose is connected with drawing machine.
Described left and right sides loading disc is semicircle, respectively is arranged with 4～12 in its circumferential 0 °～90 ° degree and loads threaded hole, and left and right sides loading disc connects spindle nose by loading threaded hole.
Be provided with and test the close-fitting cavity of test specimen between described two limited blocks.
The utility model can not only carry out the pure shear test of degree of precision, and can operate by short form test, can also carry out the shear test of varied angle.Cavity and test specimen that the utility model limited block is placed the shear test test specimen closely cooperate, so test specimen is in plane stress state, can realize the pure shear to test specimen.The utility model changes loading direction by spindle nose is installed on the different threaded holes.Whole device is easy to realize the batch testing of material property.
