Abstract
The invention of a device has four threaded bolts that engage cooperatively threaded apertures in a base. These thread bolts hold the device in a temporary yet stationary position. The device has non-magnetic metal which allows test indicators to display accurate results free from any magnetic fields. The device has a precision bore of a nominal size. The radial value of the nominal size precision bore provides for mathematical calculation of the spindle centerline to work piece distance for measuring. The device has undercuts on both of its sides to aid in removing by hand. These undercuts allow the device to pivot from its stationary position for removal without damaging the planar surface. Alternatively, the device has four magnetic inserts, pocketed upwardly from the bottom surface.
Claims20
A device for mechanically aligning a test indicator at a radial value in a machine tool spindle upon a work piece, comprising:
- a non-magnetic body, said body having a top surface and an opposite bottom surface;
- a centered bore communicating through said top surface towards said bottom surface, said bore being perpendicular to said top surface and said bottom surface;
- four connectors communicating through said top surface towards said bottom surface, each of said connectors connecting said body to the work piece;
- and,
- said bore having a circularity.
An aligning device for usage upon a work piece, comprising:
- a top surface and a mutually parallel and spaced apart bottom surface, a non-magnetic body, two mutually parallel and spaced apart ends and two mutually parallel and spaced apart sides, said sides being perpendicular to said top surface and said ends being perpendicular to said top surface and to said sides;
- said top surface, said bottom surface, said ends, and said sides defining a body
- said body having a centered bore communicating through said top surface towards said bottom surface, said bore being perpendicular to said top surface and said bottom surface;
- said bore having a circularity, said circularity being circularity no more one ten-thousandths of an inch;
- and,
- four connectors communicating through said top surface towards said bottom surface, each of said connectors connecting said body to the work piece.
An aligning device for usage with a test indicator at a radial value in a machine tool spindle upon a work piece, the work piece receiving debris, coolant, and cutting fluid during usage, comprising:
- a top surface and a mutually parallel and spaced apart bottom surface, a non-magnetic body, two mutually parallel and spaced apart ends and two mutually parallel and spaced apart sides, said sides being perpendicular to said top surface and said ends being perpendicular to said top surface and to said sides;
- said top surface, said bottom surface, said ends, and said sides defining a body;
- said body having four corners, each of said corners positioning proximate an apparent intersection of one end and one side;
- said body having a centered bore communicating through said top surface towards said bottom surface, said bore being perpendicular to said top surface and said bottom surface;
- said bore having a circularity, said circularity being circularity no more one ten-thousandths of an inch;
- four connectors communicating through said top surface towards said bottom surface, each of said connectors connecting said body to the work piece;
- and,
- each of said connectors being one of:
- a threaded aperture through said body proximate a corner and perpendicular to said top surface and a threaded bolt cooperatively engaging said threaded aperture and having a length greater than the spacing between said top surface and said bottom surface, said threaded apertures of said body each having a countersink proximate said top surface, and
- a countersunk pocket proximate a corner and positioned in said bottom surface, a magnetic insert placed into said pocket, and a threaded bolt securing said magnetic insert into said pocket, said countersink upwardly from said bottom surface wherein said threaded bolt remains contained above said bottom surface.
