More Information
Summary:A connecting rod inspecting device is provided with a work table (54) for placing a connecting rod (30) in a status where the connecting rod is positioned at a prescribed position; a slide unit (58) for reciprocating the work table (54) along the horizontal direction; and first to fourth distance sensors (60a-60d) for measuring a step quantity (D) of a step part (98) by irradiating measuring planes (94a, 94b) composed of curved surfaces with laser beams and measuring distances between the sensors and the planes irradiated with the beams. Conforming/nonconforming judgement is made by the measured step quantity (D) and a range of allowable quantities previously set.
