[0002] The so-called hardness is the ability of a material to resist the penetration of a harder object into its surface. According to different test methods and applicable ranges, hardness units can be divided into many types such as Brinell hardness, Vickers hardness, Rockwell hardness, micro-Vickers hardness, etc. Different units have different test methods and are applicable to materials or occasions with different characteristics.

[0003] A Rockwell hardness tester is a device used to measure the hardness of materials. It has various models and types. The working principle of the Rockwell hardness tester is based on the contact between an indenter applying a certain pressure and the surface of the material, and the hardness of the material is determined by measuring the depth or diameter of the indentation. This hardness test method has high precision and reliability and is widely used in industrial production, becoming an important tool for inspecting product quality and determining reasonable processing technologies.

A motor 15 is installed on the support 14. The output end of the motor 15 is connected to the rotating shaft 12 through a coupling. After all the workpieces are placed, the motor 15 is started to drive the rotating shaft 12 to rotate. Under the transmission action of the first bevel gear 11 and the second bevel gear 13, the threaded sleeve 10 rotates, thereby causing the threaded rod 5 and the sliding column 4 to move upward until the workpiece contacts the detection head 3. The hardness of the workpiece can be tested through the detection head 3.

[0030] An L-shaped plate 16 is fixed to one side of the workpiece placement seat 8, and a limiting column 17 is arranged on the L-shaped plate 16.
