US 2017/0248400 A1 · MEASURING PROBE

Abstract

A measuring probe includes: a stylus having a contact part to be brought into contact with an object to be measured; a probe housing capable of supporting the stylus on an axial center; and a detection element capable of detecting a movement of the contact part. The measuring probe further includes: two supporting members disposed in an axial direction of the probe housing, the supporting member allowing for an attitude change of the stylus; and a coupling shaft for coupling the two supporting members together. The detection element is disposed in one of the two supporting members that is farthest away from a rotational center position of rotation generated in the stylus when a measuring force is applied to the contact part from a direction perpendicular to the axial direction, to detect a strain amount of the one of the two supporting members.

Dependent claims

A measuring probe comprising:

a stylus having a contact part to be brought into contact with an object to be measured;
a probe housing capable of supporting the stylus on an axial center;
a detection element capable of detecting a movement of the contact part;
a plurality of supporting members disposed in an axial direction of the probe housing, the supporting members allowing for an attitude change of the stylus;
and
a coupling shaft configured to couple the plurality of supporting members together, wherein
the detection element is disposed in, among the plurality of supporting members, a supporting member that is farthest away from a rotational center position of rotation generated in the stylus when a measuring force is applied to the contact part from a direction perpendicular to the axial direction, to detect a strain amount of the supporting member.
