A HARDNESS MEASURING APPARATUS

摘要

A hardness measuring apparatus is provided to secure more accurate hardness measurement by adjusting the disposition angle of a specimen according to the surface shape of the specimen. A hardness measuring apparatus comprises a die(10), a guide rod(20) and a compressing part(30). The die mounts a specimen. The guide rod is coupled to one side of the die and fixed vertically. The compressing part is coupled to the guide rod, moves down from the upper side of the die and applies a vertical load to the specimen. The die includes an angle adjusting unit(40) for measuring hardness of a specimen having a curved surface.
