Abstract
A three-axis coordinate inspection machine. A pair of parallel Z axis rails are mounted atop a bearing plate having an upwardly facing horizontal bearing surface. A single X axis rail has opposite ends slidably and bearingly mounted to the Z axis rail. The X axis rail extends through a carrier which is supported by the bearing surface of the bearing plate. A vertically extending column is mounted to the carrier and slidably holds in the vertical direction one or more inspection probes which may in turn be moved along the length of the X axis rail and Z axis rails.
Claims12
A three-axis inspection machine comprising:
- a frame including a horizontal bearing surface;
- a carrier slidably mounted directly on and supported by said bearing surface;
- X rail means positioned adjacent said frame and defining an X axis, said X rail means engaged with said carrier and operable to guide said carrier atop said bearing surface slidably along said X axis;
- Z rail means positioned adjacent said frame and defining a Z axis perpendicularly arranged to said X axis, said Z rail means operable to guide said carrier atop said bearing surface slidably along said Z axis;
- a vertically extending Y column mounted to and slidable with said carrier atop said bearing surface along said X axis and Z axis and defining a Y axis perpendicularly arranged to said X axis and Z axis, said column supported by said bearing surface independently of said X rail means and Z rail means;
- and
- at least one probe slidably mounted to said Y column and movable along said Y axis as well as said X axis and Z axis into alignment with selected portions of an article to be inspected.

An inspection machine movable in three axes comprising:
- a bearing plate with a bearing surface;
- at least one Z axis rail mounted to said plate;
- at least one X axis rail positioned on said plate and perpendicularly arranged to said Z axis rail;
- a carrier slidably mounted to said plate and including a top saddle and a lower saddle removably secured together, said top saddle including bearing means supporting said carrier on said bearing surface, said X axis rail extending through said carrier with said top saddle straddling said X axis rail and with said Z axis rail located outwardly of said carrier;

A method of aligning the rotatable tool spindle of an individual machine relative to the datum base of a transfer line including the machine comprising the steps of:
- mounting to said spindle a member with a longitudinal center axis extending in the direction of a Z axis;
- arranging a plurality of inspection probes to encircle said member when mounted;
- supporting said probes on a horizontally extending bearing surface atop said datum base;
- guiding said probes in X, Y and Z directions to a first position whereat said probes encircle a first portion of said member to be operatively engaged therewith;
- moving said probe along said center axis from said first position to a remote position associated with another portion of said member remote from said first portion;
- and
- moving said machine until the XY coordinate position of said member at said first portion relative to said datum base corresponds with the XY coordinate position of said member at said another portion as checked by said probes.
