  • Patent number: 8601703
    Abstract: The positions of at least three points, which are circumferentially, and equiangularly, offset from each other, of a peripheral face of a workpiece set on a rotary table are measured using a position detection probe. The amount of runout of the axis of the workpiece and a phase position of the workpiece, at which the runout amount is largest, are calculated from the measured positions of the equiangularly offset points. The rotary table is turned to set the largest runout phase position of the workpiece in a position opposed to a workpiece contact of a centering apparatus. The relative positions of the workpiece and a position detection block are calculated using the position detection probe. The workpiece is centered by moving a centering shaft member of the centering apparatus such that the workpiece contact pushes the workpiece by a distance corresponding to the runout amount.

  • Patent number: 7137210
    Abstract: According to the measuring head, the zero point and the amount of front travel settings are facilitated. Firstly, the amount of front travel is set by allowing contacts 34, 34 to abut a master 50. Then, rotating the lever 42 in a direction indicated by an arrow E, or a close position, causes the bearing member 36 to be fastened to the swinging support shaft 28. At this time, a restoring force, or a force caused by reaction, of the bearing member 36 transferred from the bearing member 36 through the arm 38, cam plate 40 and shaft 48 to the measurement lever 32 causes the measurement lever 32 to deflect by an amount that equals to the amount of front travel, and therefore from the position where the amount of front travel is set to the zero point position. This automatically sets the zero point position.

  • Patent number: 6996913
    Abstract: An apparatus and method are provided for circumferentially measuring cross-sectional characteristics of a tubular member. The apparatus includes first and second template members that cooperably define an aperture for receiving the tubular member. At least one of the template members is adjustable so that the aperture can be adjusted between open and closed positions. A measurement device can be configured to detect the relative position of the first and second template members, thereby measuring the relative adjustment of the members between the open and closed positions. This measurement is indicative of the cross-sectional size of the tubular member, e.g., for determining the diameter of the tubular member. Alternatively, multiple measurement devices can respond to a contact force between the measurement devices and the tubular member, e.g., to determine a variation in wall thickness of the tubular member.
