Description

Technical Field

[0001] This utility model relates to the field of marking fixture technology, and in particular to a correction fixture for laser marking assistance. Background Technology

[0002] Gauge length generally refers to a specific length range marked on a specimen for measurement during mechanical property tests such as tensile testing, in order to accurately measure the amount of deformation and other related data of the material under stress. For different types of materials and test purposes, relevant national or industry standards will clearly specify the value of the gauge length. Before tensile testing, the specimen needs to be calibrated. The main methods of marking include mechanical marking, dot marking, and optical marking. The accuracy of the gauge length has a significant impact on the elongation of the material. If the actual gauge length is greater than the theoretical gauge length, the measured elongation will be lower, and vice versa. The accuracy of the marking distance affects the material test results.

[0003] Some steel grades exhibit significant uneven deformation after quenching. When using laser marking, the actual distance between two marking lines is greater than the theoretical distance due to this deformation, resulting in a lower elongation after stretching. Therefore, a correction fixture for laser marking is provided. Utility Model Content
