Design of fully automatic calibration machine for reference block based on machine vision

Ren Xiang, Lu JinYu, Tao Zecheng


In order to solve the problems of the existing standard Brinell hardness machine such as low automation, the time-consuming indentation measurement and the human influence in indentation measurement, a calibration machine for reference block was designed. It shows that this machine can reduce the influence of the temperature difference between the hardness block and the measurement platform; it eliminates the time for the indentation measuring system to find the indentation and juxtapose it with the centre of the field of view and implements fully Brinell hardness automatic calibration.
