特徴とするコイルばね粗密検査装置。 Proximity sensor means that generates an electromagnetic field, detects the strain of the electromagnetic field that occurs when the coil spring is brought close, and outputs the magnitude of the detected strain as a voltage value; When the first inspection point is approached, a first voltage value outputted from the proximity sensor means is detected, and the detected first voltage value is stored. When a second test point located at a different position in the axial direction approaches the first test point, a second voltage value output from the proximity sensor is detected, and the detected second voltage value and the second test point are A coil spring characterized by comprising a density determination means for comparing and determining the density of the coil at a first inspection point and a second inspection point of the coil spring by comparing the stored first voltage value. Roughness inspection equipment.
