APPARATUS, SYSTEM AND METHOD FOR MEASURING THREAD FEATURES ON PIPE OR TUBE END

APPARATUS, SYSTEM AND METHOD FOR MEASURING THREAD FEATURES ON PIPE OR TUBE END

A FIRST THREAD FEATURE IS MEASURED BY DETECTING WITH AN OPTICAL SENSOR (2), LIGHT THAT REACHES FROM A LIGHT SOURCE (21) LOCATED ON THE OPPOSITE SIDE OF A PIPE AXIS AND RUNS SUBSTANTIALLY IN PARALLEL TO THREAD GROOVES (A4). A CONTACT PROBE (31) OF A CONTACT SENSOR (3) IS CONTACTED WITH A THREAD FLANK...

Zusammenfassung:A FIRST THREAD FEATURE IS MEASURED BY DETECTING WITH AN OPTICAL SENSOR (2), LIGHT THAT REACHES FROM A LIGHT SOURCE (21) LOCATED ON THE OPPOSITE SIDE OF A PIPE AXIS AND RUNS SUBSTANTIALLY IN PARALLEL TO THREAD GROOVES (A4). A CONTACT PROBE (31) OF A CONTACT SENSOR (3) IS CONTACTED WITH A THREAD FLANK SURFACE (A8) TO DETECT THE SPACE COORDINATES OF THE CONTACT PROBE (31) AT THE TIME OF CONTACT, SO THAT A SECOND THREAD FEATURE IS MEASURED. THE FIRST AND SECOND THREAD FEATURES THUS DETECTED ARE COMBINED WITH EACH OTHER BY A PROCESSOR (4), AND THREAD FEATURES OF THE THREAD PROVIDED AS A MEASUREMENT OBJECT ARE THEREBY CALCULATED.
