Abstract

An exemplary base includes a first elastic element, a second elastic, two first adjustable spacers and two second adjustable spacers. The first elastic element includes two first spaced plates and a first connecting element for connecting the two first spaced plates. The second elastic element includes two second spaced plates and a second connecting element for connecting the two second spaced plates. The first connecting element and the second connecting element are not in a plane. Two first adjustable spacers connect the two first spaced plates and adjust a distance between the two first spaced plates. Two second adjustable spacers connect the two second spaced plates and adjust a distance between the two second spaced plates.

Claims

1. A contour measuring system comprising:

a base having;

a first elastic element including two first spaced plates and a first connecting element connecting ends of the two first spaced plates at a same side, the two first spaced plates and the first connecting element cooperatively defining a first spacing;

a second elastic element stacked on the first elastic element, the second elastic element including two second spaced plates and a second connecting element connecting ends of the two second spaced plates at a same side, the two second spaced plates and the second connecting element cooperatively defining a second spacing, wherein the first connecting element and the second connecting element are not in a same plane;

at least one first adjustable spacer connecting the two first spaced plates of the first elastic element for adjusting a distance between the two first spaced plates; and

at least one second adjustable spacer connecting the two second spaced plates of the second elastic element for adjusting a distance between the two second spaced plates; and

a contour measuring probe disposed on the base, the contour measuring probe having a tip extension for touching a surface of an object.

2. The contour measuring system as claimed in claim 1, wherein the contour measuring probe further comprises at least one hollow tube, the tip extension being driven by the at least one hollow tube.

3. The contour measuring system as claimed in claim 2, wherein the at least one hollow tube comprises an air discharge system configured to eject at least part of the flux of air in the at least one hollow tube out of the at least one hollow tube.

4. The contour measuring system as claimed in claim 3, wherein the air discharge system is a combination consisting of any of at least one air eject hole defined in the cylinder base of the at least one hollow tube, and at least one air eject hole defined in a sidewall of the at least one hollow tube.

5. The contour measuring system as claimed in claim 1, wherein the contour measuring probe further comprises a linear measuring scale and a displacement sensor, one of the linear measuring scale and the displacement sensor moves following the tip extension.

6. A contour measuring system comprising:

a base having;

a first U-shaped element comprising two first leg portions;

a second U-shaped element comprising two second leg portions, the second U-shaped element stacked on the first U-shaped element, wherein one of the first leg portions is in contact with one of the second leg portions, and the first U-shaped element and the second U-shaped element face different directions;

at least one first adjustable spacer connecting the two first leg portions for adjusting a distance between the two first leg portions of the first U-shaped element;

at least one second adjustable spacer connecting the two second leg portions for adjusting a distance between the two second leg portions of the second U-shaped element; and

a contour measuring probe disposed on the base, the contour measuring probe having a tip extension for touching a surface of an object.

7. The contour measuring system as claimed in claim 6, wherein the first adjustable spacer comprises a bolt and a nut fixed to the bolt, and the second adjustable spacer comprises a bolt and a nut fixed to the bolt.

8. The contour measuring system as claimed in claim 6, wherein the first U-shaped element and the second U-shaped element face perpendicular directions.

9. The contour measuring system as claimed in claim 6, wherein the first U-shaped element and the second U-shaped element are welded or glued together.
