Claims

[Scope of utility model registration request]

A roller conveyor that carries in workpieces for hardening state inspection and carries out inspected workpieces, a centering shaft that lifts the workpieces one by one from the roller conveyor by a rising rotation cylinder and adjusts the phase after being lifted, and the phase alignment shaft. A positioning head that positions the aligned workpieces in the horizontal direction, and a positioning device equipped with the positioning head are attached via balance springs, and the contact with the outer surface of the workpieces is measured using eddy currents that soft-touch with the positioning of the workpieces. 1. An automatic hardening state detection device for an inner peripheral surface hardened product, comprising a sensor and detecting the hardening state of the inner peripheral surface of the workpiece based on a change in impedance value by a measurement sensor applied from the outer surface of the workpiece.
