Object hardness measuring device and method

An object hardness measuring method for measuring hardness of a measurement object, the measuring method comprising:

• moving a second side portion with respect to a first side portion by a pedestal unit including a bottom plate and a slide rail assembly attached to a top surface of the bottom plate such that the first side portion is in contact with one side surface of the measurement object and the second side portion is in contact with a second side surface of the measurement object, the second side surface being disposed at an opposite end with respect to the one side surface of the measurement object;
• holding the measurement object by a holding unit connected onto the slide rail assembly of the pedestal unit;
• moving the holding unit between the first side portion and the second side portion by the slide rail assembly;
• and
• measuring a load acting on the measurement object by the first side portion and the second side portion when the second side portion is moved with respect to the first side portion such that the first side portion presses the one side surface and the second side portion presses the second side surface, and at least one of a movement distance of the second side portion with respect to the first side portion and a change amount of the load when the second side portion is moved either at a predetermined speed or to a predetermined position.

• a pedestal unit including a bottom plate and a slide assembly attached to a top surface of the bottom plate;
• a load unit that applies a load to the measurement object by moving the second side portion with respect to the first side portion such that the first side portion presses the one side surface and the second side portion presses the second side surface;
• a measuring unit that is able to measure, in a state where the load acts on the measurement object, at least one of a movement distance of the second side portion with respect to the first side portion and a change amount of the load when the second side portion is moved either at a predetermined speed or to a predetermined position;
• and a holding unit connected onto the slide assembly of the pedestal unit, wherein the holding unit is able to hold the measurement object, and is movable by the slide assembly between the first side portion and the second side portion.
