CONTOUR MEASURING PROBE
First Claim
1. A contour measuring probe, comprising:
- at least one tube guide;
a tip extension for touching a surface of an object, the tip extension being linearly movable relative to the at least one tube guide;
at least one hollow tube partly running through the at least one tube guide and linearly slidable in the at least one tube guide, the at least one hollow tube being configured to be driven by a flux of air pumped on a sidewall of the at least one hollow tube to push the tip extension to move, at least part of the flux of air pumped on the sidewall of the at least one hollow tube being ejected out of the at least one tube guide;
a linear measuring scale configured to display values of displacements of the tip extension, the linear measuring scale being fixed relative to one of the at least one tube guide and the tip extension; and
a displacement sensor configured to detect and read the displacement values of the tip extension displayed by the linear measuring scale, the displacement sensor being fixed relative to the other one of the at least one tube guide and the tip extension.

Abstract
An exemplary contour measuring probe (10) includes a tube guide (12), a tip extension (20), a pair of hollow tubes (16), a plurality of pipes (104, 106), a linear measuring scale (18), and a displacement sensor (19). The tip extension (20) is configured to touch a surface of an object (50). The hollow tubes (16) are configured to be driven by a flux of air to push the tip extension (20) to move. The pipes (104, 106) are obliquely disposed in a tube guide (12) relative to the hollow tubes (16). The pipes (104, 106) allow the flux of air to be pumped on a sidewall of the hollow tubes (16). A part of the flux of air is ejected out of the tube guide (12). The linear measuring scale (18) and the displacement sensor (19) are respectively fixed relative to one of the tube guide (12) and the tip extension (20). The linear measuring scale (18) displays values of displacements of the tip extension (20). The displacement sensor (19) detects and reads the displacement values displayed by the linear measuring scale (18).

12. A contour measuring probe, comprising:
-
a tip extension for touching a surface of an object; at least one driving member being configured to be driven by a flux of air pumped on a sidewall of the at least one driving member to push the tip extension to move; and at least one pipe for allowing the flux of air to be pumped on the sidewall of the at least one driving member, an angle defined by an extension direction of the at least one pipe relative to the axis of the driving member being in a range from greater than 0 degree to less than 90 degrees. - View Dependent Claims (13, 14, 15, 16)
