Description

Automatic positioning tool for testing compression strength of material Technical Field The utility model relates to the field of compression strength testing and positioning tools, in particular to an automatic positioning tool for testing the compression strength of a material. Background In the fields of material science and engineering, the compressive strength test is one of core means for evaluating the mechanical properties of materials, and is widely applied to the industries of building materials, aerospace, mechanical manufacturing and the like. With the development of new material technology, the types and specifications of samples to be tested are increasingly diversified, ranging from standard-sized concrete cube test blocks (such as 150mm×150 mm) to metal members with special-shaped cross sections (such as I-shapes and circular tube shapes), and even small-sized precise samples (such as micro-electromechanical system elements). The existing full-automatic compression strength testing machine directly carries out compression strength testing by placing materials on a workbench surface, when the materials are tested in different specifications and shapes, the materials can move to a certain extent when being extruded due to the shapes, the load direction is inconsistent with a main shaft of the materials due to material deflection, additional bending moment is generated, and measurement errors are caused. Disclosure of utility model In order to make up for the defects, the utility model provides an automatic positioning tool for testing the compression strength of a material, and aims to solve the problem that a sample deviates from a main shaft of the material to generate additional bending moment and generate measurement error due to shape difference in the prior art.
