Clamp device for detecting shear strength of sample

Abstract

The invention relates to a clamp device for detecting shear strength of a sample. The clamp device comprises a horizontal clamping end, wherein the upper surface of the horizontal clamping end is provided with a square groove, the end of the square groove is provided with a rotating clamping end through a hinge shaft, and a fixing screw is arranged at both ends of the rotating clamping end, and the root of the rotating clamping end is matched with a square groove; the inner side of the rotating clamping end is provided with a concave first sample groove, the middle part of the square groove isprovided with a second sample groove corresponding to the first sample groove, and the first sample groove and the second sample groove are used for placing samples of products. The clamp device provided by the invention has the advantages of compact and reasonable structure and convenient operation; by placing a sample processed according to a certain size requirement in the square groove in theclamp, and stretching a clamping end of a fixing clamp of a sample machine according to a test requirement, the stable progress of a test process is effectively ensured, the mechanical property of atest sample is actually reflected, and the increasingly rigorous scientific research requirement is met.

Description

technical field [0001] The invention relates to the field of detection devices, in particular to a fixture device for detecting the shear strength of samples such as diffusion welding, explosive welding and brazing. Background technique [0002] At present, with the widespread application of diffusion welding, explosive welding and brazing, when researchers find that it is no longer possible or difficult to test the tensile strength of their samples, they often use the shear strength test to characterize the mechanical properties of the material. However, the size of the sample processing is often relatively small, and there will be problems such as the testing machine cannot be clamped or the clamping is not firm, which will lead to large deviations in the test data, which cannot truly reflect the mechanical properties of the sample, and seriously affect the test progress. , reducing production efficiency. Contents of the invention [0003] In view of the shortcomings in...
