Three-dimensional displacement gage
First Claim
1. A three-dimensional displacement gauge comprising:
- a housing;
probe rotatably and slidably mounted on the housing, the probe being slidable along a first direction and having a contact member attached at one end thereof;
two emitting means mounted on the probe each for emitting a light beam;
a two-dimensional measuring means fixed to the housing for detecting the light beams struck thereon;
a biasing spring for biasing the probe toward the contact member;
a limit switch attached to the housing for detecting whether or not the probe moves in the first direction;
wherein the two-dimensional measuring means detects the light beams struck thereon so as to measure small displacement of the contact member of the probe either in the first direction or in a second direction perpendicular to the first direction.

Abstract
A three-dimensional displacement gauge comprising a housing, a probe rotatably and slidably mounted on the housing, the probe is slidable along a first direction and having a contact member attached at one end thereof, two emitting members mounted on the probe each for emitting a light beam, two-dimensional measuring member such as a position sensor fixed to the housing for detecting the light beams, a biasing spring for biasing the probe toward the contact member, and a limit switch attached to the housing for detecting whether or not the probe moves in the first direction. The two-dimensional measuring member detects the light beams struck thereon so as to measure a small displacement of the contact member of the probe either in the first direction or in a second direction perpendicular to the first direction. In another mode, the two emitting members are mounted on the housing, and a mirror is mounted at the other end of the probe, and the two-dimensional measuring element detect the light beams struck thereon from the emitting members by way of the mirror.

7. A three-dimensional displacement gauge comprising:
-
a housing; a probe rotatably and slidably mounted on the housing, the probe being slidable along a first direction, the probe having a contact member attached at one end thereof and a mirror mounted on the other end thereof; two emitting means mounted inside the housing each for emitting a light beam; a two-dimensional measuring means fixed inside the housing for detecting the light beams struck thereon from the emitting members by way of the mirror; a biasing spring for biasing the probe toward the contact member; and a limit switch attached to the housing for detecting whether or not the probe moves in the first direction, wherein the two-dimensional measuring means detects the light beams struck thereon so as to measure a small displacement of the contact member of the probe either in the first direction or in a second direction perpendicular to the first direction. - View Dependent Claims (9)
