Patent granted for an object hardness measuring device
A recently granted patent (Publication Number: US11768141B2) describes an object hardness measuring device and method for measuring the hardness of a measurement object. The device includes a first side portion and a second side portion that press against opposite sides of the measurement object. A pedestal unit, which is movable, is attached to the second side portion. A load unit applies a load to the measurement object by moving the second side portion with respect to the first side portion. A measuring unit is used to measure either the movement distance of the second side portion or the change in load when the second side portion is moved.
The device also includes a holding unit connected to a slide rail assembly on the pedestal unit. This holding unit is used to hold the measurement object and can be moved between the first and second side portions.
The method for measuring hardness involves moving the second side portion with respect to the first side portion using the pedestal unit. The measurement object is held by the holding unit, which is moved between the first and second side portions using the slide rail assembly. The load acting on the measurement object is measured by the first and second side portions, along with either the movement distance of the second side portion or the change in load when the second side portion is moved.
In another embodiment of the invention, the pedestal unit includes a rotation table that allows the holding unit to rotate along the top surface of the bottom plate.
Overall, this patent describes a device and method for accurately measuring the hardness of an object by applying a load and measuring the resulting movement or change in load. The device includes a movable pedestal unit and a holding unit for securing the measurement object. This invention could have applications in various industries where hardness testing is important, such as manufacturing and materials science.
