Technical Field
The utility model mainly relates to the field of deflection measuring equipment, in particular to a portable deflection measuring device.
Background
In the prior art, the residual stress of a layer cutting method test sample is that a sample blank is firstly cut from the sample, then the sample blank is processed into a layer cutting method sample, and then the sample is placed on a fixed deflection measuring device to measure deformation deflection, wherein the layer cutting method is only suitable for rolling plates. There is a problem in that when we study the profile or other similar structural material, we also need to cut the sample from the body and then test it. However, because the stress distribution of the profile sample is uneven, a part of residual stress can be released from the sample blank in the cutting process, and therefore, for the structural material, the result measured by the original layering method device cannot reflect the actual residual stress of the material.
