Description

Technical Field

[0001] The utility model relates to the field of dynamometer measurement, in particular to a tooling fixture applied to dynamometer measurement. Background Technique

[0002] The dynamometer is based on the fact that the resonant frequency of a vibrating taut steel string is proportional to the strain or tension of the steel string. This basic relationship can be used to measure various physical quantities such as strain, load, force, pressure, temperature, and inclination.

[0003] At present, when the dynamometer measures the tensile strength of materials, it is usually manually operated to clamp and fix the materials with a fixture, without a structure for automatically clamping and fixing them, which reduces the fixing speed during the tensile measurement of the materials and affects the subsequent measurement efficiency of the dynamometer. For this reason, we propose a tooling fixture applied to dynamometer measurement to solve the above problems. Content of the Utility Model
