  • Thread shape measuring apparatus and measuring method
    Patent number: 11313675
    Abstract: A thread shape measuring apparatus includes: a first illuminating unit that has an optical axis orthogonal to a cross section including a thread axis, and illuminates the thread portion; a second illuminating unit that has an optical axis that forms an angle ? larger than a lead angle ? of the thread portion with respect to the direction orthogonal to the cross section and illuminates the thread portion; an image-capturing unit that has a visual axis parallel to the optical axis of the first illuminating unit, includes a telecentric lens, has a focusing position matching the cross section, and detects, out of the light emitted from the first illuminating unit or the second illuminating unit, light that has not been blocked by the thread portion to capture an image of the detected light; and an operation unit that calculates a shape of the thread portion based on the captured image.
