Abstract
The utility model discloses a fixture structure for a metal sample electrified tension test, belonging to the technical field of test fixtures. The fixture structure comprises a clamping base, an electric insulation rod matched with the clamping base in a pluggable manner, a first electric insulation isolation sheet and a second electric insulation isolation sheet which are arranged on the clamping base in a face-to-face manner, wherein the electric insulation rod passes through the first electric insulation isolation sheet and the second electric insulation isolation sheet for limiting the first electric insulation isolation sheet and the second electric insulation isolation sheet on the clamping base. Because the clamping base can be located on a tension tester, and the first electric insulation isolation sheet and the second electric insulation isolation sheet are limited on the clamping base through the electric insulation rod, when a metal sample is subjected to tension test when a current state is introduced, the metal sample is placed between the first electric insulation isolation sheet and a second electric insulation isolation sheet and limited by the electric insulation rod, thus the metal sample can be limited, and electric insulation between the metal sample and the clamping base can be ensured, and the tension tester is prevented from being influenced by current and the safety is ensured.
Description
Technical field
The utility model belongs to test technical field of tooling clamps, is specifically related to the clamp structure that the charged tension test of a kind of test button is used.
Background technology
Aforesaid test button tension test refers to test button is placed on cupping machine and under the state that test button is passed into electric current test button is carried out to tension test, to predict the mechanical property (mechanics parameter) of metal material, mechanical property is as yield strength, tensile strength, extensibility and reduction of area, etc.
Because corresponding variation can occur because of the variation of applied environment for the performance of material, thereby when being applied to special and/or harsh environment, the performance change of material more receives people's concern.For example, in electronic devices and components encapsulation field, brazing filler metal alloy solder joint had both played mechanical connection effect, also played electrical connection (electrical connection) effect simultaneously, because electronic component is subject to the double action of power and electric current, thereby the mechanical property of examination brazing filler metal alloy under the function of current seems particularly important.
