US Patent:

48282405, May 9, 1989

Filed:

Dec 7, 1987

Appl. No.:

7/129052

Inventors:

Francis S. Longenecker - Englewood OH
Kevin J. Moeder - Englewood OH
Jeffrey L. Wolff - Dayton OH

Assignee:

TE-CO. - Englewood OH

International Classification:

B23Q 306

US Classification:

269 47

Abstract:

A workpiece is clamped to the table of a machine tool by a toggle clamp or edge clamp supported for rotation by the head portion of a stud threaded into a hole within a member secured to the table. The member may comprise a column or a column extender each having a frame with precisionly attached plates having X-Y grid patterns of alternating threaded holes and precision bores. A grid or base plate with an X-Y pattern of holes and bores may also receive an angle plate which also has an X-Y grid pattern of threaded holes and precision bores in addition to counterbores and precision angle positioning bores which receive pins for precisely locating the angle plate at a selected predetermined angle relative to the grid or base plate. The workpiece may also be secured to T-slot plates which are retained in precision locations on a base plate to define precision T-slots for receiving T-nuts. An adjustable radius locator system provides for precisely locating on the base plate a workpiece having two precision holes.
