摘要： PURPOSE:To obtain a hardness value inexpensively using a general dial gauge by magnifying the displacement of an indenter to the size of 6-8 times and measuring it with the dial gauge having predetermined scale. CONSTITUTION:A magnifying lever 14 for magnifying the displacement of an indenter 8 to the size of 6-8 times is arranged at a Rockwell hardness tester for measuring the hardness by applying pressure to the indenter 8 by a weight 25 for a testing load. Then, the spindle 31 of a dial gauge 30 is brought into contact with the free end 14b of the lever 14. This dial gauge 30 may be a gauge which can be obtained in the market and rotates its needle by one revolution upon displacement of 1mm. The scale portion 45 of the gauge 30 is so calibrated that the scale range of 0-100 in hardness is set at 60-80% of the entire circumference of the scale portion 45 as shown. Thus, the hardness value can be readily visually read inexpensively without using special tool.

摘要： PURPOSE:To enable to cope with various hardness measurements with one set of hardness meter, by providing the pressure unit selection set through simple selection of reference weight. CONSTITUTION:The reference weight coil springs 15 to 17 are externally coupled to the pressure unit axis 1, they are supported with the axis 1 via the spring holders 1c, 12 to 14, female screw hole 18 is placed under the support cylinder 3, the three types of operational cylinders 19 different in thickness is made removable, and fitting nuts 4, 4' are made removable under the lower end of the axis 1. Thus, the operation cylinder 19 of desired thickness is mounted to the female screw hole 18, and the coil springs 15 to 17 for reference weight are selectively compressed for required number, allowing to easy selection of the reference weight. The fitting nuts 4, 4' are mounted to the axis 1, 1 or 2 pressure unit holder 1a or 6 is fitted to the axis 1 to achieve desired purpose.

摘要： PURPOSE:To make easy the selection of reference weights two or more types, by simplifying the reference weight selection set. CONSTITUTION:Three sets of reference weight coil springs 8 to 10 are coupled externally on the pressing axis 1, they are supported on the axis 1 via the spring bearings 1c, 5 to 7, the female screw hole 11 is formed inside the support cylinder 3, and the operation cylinder 12 of three types of thickness can be removable. Thus, when the operation cylinders 12 of thin, medium and thick thickness are mounted in the female screw hole 11, the reference weight coil springs 8, 9, 10 are sequentially pressed to set the fixed coil spring 17, reference weight coil spring 8, coil springs 17, 8, 9, and coil springs 17, 8 to 10, for the weight of three types of strength. When turning the weight lever 21, and when the axis 1 is depressed down via the weight axis 19, three types of reference weights can selectively be loaded to the test piece 27 only with the selection of the operation cylinder 12 easily.
