The invention discloses an auxiliary tool for testing the mechanical property of a material and a using method. The auxiliary tool comprises an upper clamp and a lower clamp which are the same in structure and oppositely arranged, and each clamp comprises a sleeve, a clamping block, a water jacket, an ejector rod and a nut; one end of the sleeve is provided with an internal thread, and the clamping block is installed on the sleeve through an external thread; an internal thread connected with a sample piece is arranged in the middle of the clamping block; the other end of the sleeve is providedwith an external thread, a first-stage annular step and a second-stage annular step are arranged at one end of the nut, and an inner ring of the first-stage annular step is connected with the other end of the sleeve through an internal thread; the ejector rod is arranged in the sleeve, one end of the ejector rod abuts against the clamping block, and the other end of the ejector rod abuts againstthe second-stage annular step; and the other end of the nut is connected with one end of the water jacket, and the other end of the water jacket is fixed on a tester. The defects that manual operationis needed for testing the mechanical property of a material, the risk is large and the labor intensity is high are overcome, the coaxiality is good, the stress is uniform in the sample piece clampingprocess, and the requirement for the high-frequency fatigue test of engine parts is met.
Description
technical field [0001] The invention relates to the technical field of test fixtures, in particular to an auxiliary tool for testing the mechanical properties of materials and a usage method. Background technique [0002] Engine test refers to the experiment that uses special test and test equipment to test the performance, reliability and durability of the engine. The working conditions of the engine are usually harsh, in the working state of high temperature, high pressure and high speed rotation. In order to improve the performance, reliability and life of the engine, it is necessary to fully grasp the temperature, pressure, corrosion, clearance and stress of the engine under different working conditions and so on. Engine parts need to be tested for material mechanical properties under high temperature conditions, such as high frequency fatigue tests for testing material fatigue mechanical properties under high temperature conditions. [0003] At present, most enterpris...
