Abstract

The invention discloses an auxiliary tool for carrying out a stretching test on an engine part, belongs to the technical field of engine part test, and solves the problems of inaccurate reading and low efficiency of traditional stretching equipment. The tool comprises an extensometer and two clamping mechanisms, the extensometer is installed in the middle of a sample, each clamping mechanism comprises a clamp body, a jaw is arranged at one end of the clamp body, first wedge faces are arranged on the inner walls of the two sides of the jaw, clamping blocks are arranged on the two sides of an inner cavity of the jaw, clamping parts are arranged on the sides, close to each other, of the two clamping blocks, and the first wedge faces are arranged on the first wedge faces. Second wedge faces are arranged on the sides, away from each other, of the two clamping blocks, a connector is arranged at the other end of the clamp body, and the clamp body is provided with a driving mechanism. The invention further discloses a method for carrying out the tensile test on the engine part. According to the auxiliary tool and the method for carrying out the tensile test on the engine part, the auxiliary tool is added on original tensile equipment, so that the problem of inaccurate reading is solved, the working efficiency is improved, and the potential quality hazard of the part is reduced.

Description

technical field [0001] The invention relates to the technical field of engine parts testing, and more particularly, to an auxiliary tool and method for tensile testing engine parts. Background technique [0002] How to perform tensile test on engine parts, the conventional method is to use manual installation. First, one end of the part to be tested is fixed, and the other end is hung with a dynamometer. reading. This method controls the uneven tensile force, easily exceeds the limit value, and easily breaks or cracks the part to be tested. There are inaccurate readings, low work efficiency, and large hidden quality problems, which greatly reduces the effect of tensile testing. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is aimed at some of the above-mentioned deficiencies of the prior art. The purpose of the present invention is to provide an auxiliary tool and method for tensile testing of engine parts, so as to solve th...
