Abstract
Disclosed is a universal system for the support and positioning of a workpiece for use with a device such as an inspection system. A plurality of individual alignment devices are inserted into predetermined holes of a platform having a matrix of holes. Functions of individual alignment devices include support, clamping, datum point positioning and providing reference points. Each alignment device usually includes stanchions of varying length. Each stanchion is capable of being connected to another stanchion. Once the alignment device is positioned in a hole it can be fine tuned in all directions to get an exact location. Workpieces of widely varying types, shapes and sizes can thus be positioned using the same set of alignment devices.
Claims18
A workpiece supporting apparatus comprising:
- a platform having a matrix of holes in predetermined locations;
- a plurality of alignment devices, each alignment device being secured in a selected hole and readily moveable and securable from one hole to another such that the relation of said alignment devices to each other is known;
- and
- said alignment device being adjustable in at least one of three coordinate axes and having a sufficient range of movement to support and position a variety of different workpieces, each alignment device being assembled from a plurality of interchangeable elements, and each alignment device including at least one elongated stanchion having a predetermined length, said elongated stanchion includign means at one end surface thereof for connecting another elongated stanchion thereto along a common axis and at least one stanchion referencing the workpiece relative to the platform, said elongated stanchion is removably connected at its lower end to one of the holes in the platform and carrying another element at its upper end;
- and
- said plurality of interconnected elements includes an extension element secured to the upper end of the at least one stanchion, said extension element carrying a rotatable member for rotating at least one reference bushing in a plane substantially parallel to the platform, and said reference bushing being movably positionable.

Apparatus for supporting a workpiece comprising:
- a plurality of interconnected elements, at least one element being an elongated stanchion having a central axis, said elongated stanchion including means for connecting said stanchion to at least one other stanchion at its lower end such that a central axis of said other stanchion substantially aligns with the axis of said elongated stanchion, and carrying the remaining elements at its upper end, a first remaining element secured to the upper end of the elongated stanchion, said first element carrying a rotatable member, said rotatable member being rotatable about an axis substantially parallel to but spaced from the central axis of the elongated stanchion, and wherein said rotatable member positions a second remaining element in a plane substantially perpendicular to the substantially parallel axis without substantially deviating from the plane, said second remaining element being rotatable about an axis substantially perpendicular to the substantially parallel axis for positioning a third remaining element about the substantially perpendicular axis and at least one member having a slot, said one member being positionable by said rotatable member, and means for positioning another element along said slot.
Apparatus for supporting a workpiece comprising:
- a plurality of interconnected elements, at least two of the elements being coupling elements, said coupling elements including means for removably securing said coupling elements to at least one support device at their lower ends and means for removably securing said coupling elements to a single briding member at their upper ends, said bridging member being removably secured to said coupling elements at a bottom surface of said briding member, and said bridging member including a first slot and a first slidable assembly, said first slidable assembly being positionable along said first slot and lockable at any point therein and said first slidable assembly being removable from said first slot.
Apparatus for supporting a workpiece comprising:
- at least two elongated stanchion elements, each stanchion element having an internal threaded bore at one end and an external threaded tip portion at the other end and wherein the tip portion of one stanchion element is threaded into the internal bore of another stanchion element and wherein said at least two stanchions are interchangeable;
- an end cap element, said end cap element having an internal threaded bore at one end and an external threaded tip portion at the other end, said threaded tip portion of said end cap threaded into the internal threaded bore of one of the at least two stanchion elements;
- and
- a tip element, said tip element having an external threaded portion, said external portion threaded into the internal threaded bore of the end cap and including a nut for securing said tip element into said internal threaded bore of the end cap at a predetermined location.
