Abstract:
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 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, a flowing direction of the flux of air being obique to the moving direction of the tip extension, 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.
