Abstract: A portable coordinate measuring machine has an adjustment mechanism that allows fine movement of the base into alignment with reference lines or planes. The machine has a heavy base pivotally mounted at one end on a first support and slidably mounted at the other end on a second support. The second support has a pair of arcuate slots that receive a pair of pins connected to the base member. A lead screw is connected to the base member and threadedly engaged with a nut. The nut is pivotally connected to the second support. A user turns a handle or wheel on the lead screw to cause the base to pivot about the pivot point of the first support. This pivoting motion effects fine adjustment of the base's position to align it with reference lines or planes.

Abstract: The invention contemplates an articulating head having bearings of reproducible travel behavior, for precision angular displacment of a mounted probe-pin, about each of two orthogonal component axes of rotation. The precision of angular displacement relies upon high-resolution angle encoders for reading the instantaneous angle for each of these component axes of rotation and for reporting the same to the computer of a coordinate-measuring machine. Active position-control circuits use the angle encoders for controlling drive about the respective component axes of rotation, all in conjunction with a given program of measurements by the coordinate-measuring machine. A probe holder mounted to the articulating head can be oriented to any desired angular aspect with respect to the workpiece feature to be measured or scanned, and measurements can be made solely by controleld actuation via one or both drives on the respective axes of the articulating head, i.e.

Abstract: A probe head for a coordinate-measuring instrument has a torsionally rigid, play-free and friction-free probe-suspension system which defines a three-dimensional coordinate system wherein the work-contact pin of the probe is deflectable in all three directions in space. For each of the three coordinate directions, an incrementally operating displacement-measuring system is provided, and each such system is associated with a zero indicator for recognition of the zero position of the system. Upon initial contact of the probe with the object to be measured, a trigger pulse is produced via a sensor. A subsequent electronic system processes the different signals delivered by the probe head so that optional operation is available either as a switching probe head or as a measuring probe head.

Abstract: A quick release mounting arrangement for a portable gauging sensor utilizes three locating surfaces to establish a positive, repeatable mounting for the releasable sensor at any desired number of locations on a gauging fixture. A landing pad at each mounting location provides a depressed cavity in a first face for receipt of a first locating surface carried by the sensor housing, and the landing pad further provides a grooved surface in a second face for receipt of the second and third locating surfaces carried by the sensor body. At least one of the three locating surfaces is movable under spring tension to provide a quick connect/disconnect feature to the sensor mounting arrangement.

Abstract: In a sensor head of a measuring machine, for at least one coordinate, a straight line guiding mechanism is provided between two base parts. Springs acting in this coordinate bring the two base parts into abutment. To achieve a slackfree, stable position of rest, a stop element with a stop face for each base part is displaceable in both directions of the coordinate, counter to the action of a spring. Both stop faces point in the same direction of the coordinate. For movement, stroke lengths are free on both sides.

Abstract: Apparatus for positioning a number of nondestructive dud detectors above a conveyor includes side support members to which a rotatable threaded positioning bar is mounted. The positioning bar includes a number of serially placed threaded positioning segments. The dud detectors are supported by the positioning bar through individual dud detector supports. Each dud detector support includes a threaded block which engages the threaded positioning bar. The threaded positioning segments have threads with different pitches. Rotation of the positioning bar cause the dud detectors to move axially along the positioning bar, and thus transversely over the conveyor belt, at unequal rates. The thread spacing or pitch for each threaded positioning segment is chosen so that the separation between adjacent dud detectors changes while keeping the dud detectors equally spaced.

Abstract: A dimensional measuring and checking machine mounts a bridge structure (12) on legs (22) which are supported on a base (10) by air bearings. The varying forces due to travel of a probe mounting carriage (24) create vertical displacements of the bearings and movement of the bridge (12) out of alignment. To compensate for this, and thus enable high accuracy measuring, a chain (34) moves with the bridge (12), rotating a spindle (42) at one end of the machine, and thus moving the legs (22) at that end so levers (48) and pivot blocks (52) vary the height of the bridge (12).
