An indexing head has a plurality of co-axial discs rotatable relative to each other. A first disc carries an indexing pin receivable in a series of equi-angularly spaced recesses of a second disc. A third disc is angularly settable relative to the second disc by means of gauge blocks, and is lockable after setting by locking means. A tool shank can be releasably held in an axial bore of the first disc. When used in an oil bath of an erosion machine, the head is fitted with a bellows skirt to pre...

In a spatial coordinate measurement system using an articulated arm and associated electronic data processor, the workpiece having locations to be measured is held by a carrier rotatively supported about an axis. An angular encoder feeds into the processor the relative orientation of the carrier about the axis. The processor virtually translates the origin or point of reference of the arm as a function of the orientation of the carrier so that the carrier and workpiece can be rotated to place th...

A rotary layout stand for use in pattern making formed by a base having two rollers mounted thereon and a substantially vertical circular panel mounted on the rollers of the base for rotation thereon, with the circular panel having a central opening adapted to have a match plate fixed thereon and having releasable means adapted to prevent rotation of the circular panel on the rollers.

A compact stage includes a rotary driver and a vertical linear driver that are in the same horizontal plane, which advantageously reduces the height of the device. The stage may include a rotating shaft to which a chuck is mounted. A rotary drive, which may be an annular rotary drive, is coupled to and rotates the rotating shaft. A linear drive is also coupled to the rotating shaft and in one embodiment extends through the center of the annular rotary drive. The linear drive moves the rotating s...

A layout fixture capable of supporting workpieces weighing up to two tons and easily maneuvering and indexing the workpiece about two mutually perpendicular axes of rotation while also controlling both vertical and lateral translation. The workpiece is supported above a measuring table and can be moved at least halfway across the table to facilitate the layout and checking of the workpiece.

A measuring tool for a blade cuff mounted on a rotor blade assembly includes a cam follower assembly which simulates a longitudinal profile of an ideal blade cuff within a contour plane. A cam lock locks the gauge at a desired longitudinal position along a central axis to measure a radial plane defined around the blade cuff as the blade cuff profile fixture is rotated relative the base and cam follower assembly. A master block is removably mounted to the blade cuff fixture to simulate an ideal b...

A fastener dimension measuring machine is disclosed including a rotatable plate containing a series of openings in the plate of different sizes and diameters to allow insertion of a wide variety of different size and shaped fasteners. Flat head protrusion, outside diameters, head heights, lengths and tolerance compliance may be measured in the machine. A measuring member is located above the plate, and is movable vertically between a fastener measuring and a fastener insertion or removal positio...

Metrological apparatus is provided with a turntable (4) which is movable horizontally and pivotally for centering and levelling. The turntable (4) is supported at three points (A,B,P), one (P) of which is fixed and the other two (A,B) of which are vertically movable by motorized jacks. Centering and levelling is achieved automatically by means of a computer (72) which calculates the required horizontal and pivotal movements of the turntable (4) from data obtained by sensing the workpiece surface...

A system for automatically orienting a cylinder head such that a valve guide inserted into a guide is perpendicular to the ground.

Apparatus used for dimensional inspection of a pipe spool, and further for marking or cutting and finishing of the both ends by means of laying at least an end tangent horizontal and having each center of the cutting end section in a line which is parallel to a base frame.
