さを自動計測し表示部１３に表示させるものである。2. Description of the Related Art A fully automatic Rockwell hardness tester 10 as shown in FIG. 3 is used for the hardness test of tillage nails.
This is because the anvil 1 is attached to the sample support unit 11, the object to be measured is sandwiched between the upper surface of the anvil and the lower surface of the sample surface detection unit 13, and the indenter provided inside the sample surface detection unit measures the object to be measured. By pushing into the surface with a reference load, the Rockwell hardness is automatically measured and displayed on the display unit 13.

いていた。On the other hand, the tillage claw has a shape as shown in FIG. 4, and the surface of the base portion 21 is processed into a flat surface.
Other parts generally do not have a flat surface. Therefore, when performing the hardness test of the tilling nail using the above-mentioned fully automatic Rockwell hardness tester, the base 21 of the tilling nail is ground to be a measurement surface, and the anvil 16 having a flat upper surface as shown in FIG. 5 is used. Was used.

規格から外れてしまう恐れがある。However, when carrying out the hardness test of a tilling nail using the above-mentioned fully automatic Rockwell hardness tester, it is necessary to polish the measuring surface of the tilling nail which is the object to be measured. However, if the base portion 21 of the tillage nail is polished, the thickness of the base portion is reduced, and there is a possibility that the thickness of the tillage nail and the mounting holder may deviate from the required standard thickness of the tillage nail base portion.

た。When an anvil 16 having a flat upper surface as shown in FIG. 5 is used to support a portion other than the base of the tilling claw as a measurement surface, the back surface of the measurement surface supported by the anvil is a curved surface. Therefore, there is a problem in that the object to be measured is not stably supported and proper hardness cannot be measured.

目的とするものである。The present invention has been made to solve the above-mentioned problems, and in a hardness test of a tilling nail using a fully automatic Rockwell hardness meter, a portion other than the base portion of the tilling nail is used as a measurement surface. It is an object of the present invention to provide an anvil that can stably support an object to be measured even if the measurement surface is a curved surface in order to enable appropriate hardness measurement even in the case of the above.
