Abstract
A tool for measuring seal slot position includes a tool shaft having a longitudinal axis, a pin eccentrically disposed at one end of the tool shaft relative to the longitudinal axis, and a disk member disposed at an opposite end of the tool shaft that facilitates rotation of the tool shaft and pin in the seal slot. The tool provides for increased accuracy in measuring seal slot position such as turbine nozzle seal slot position.
Claims9
A tool for measuring seal slot position, the tool comprising:
- a tool shaft having a longitudinal axis;
- a pin eccentrically disposed at one end of the tool shaft relative to the longitudinal axis, the pin being sized to fit into a seal slot;
- and
- a disk member disposed at an opposite end of the tool shaft, the disc member facilitating rotation of the tool shaft and pin in the seal slot, wherein the seal slot position is measured based on an amount of tool shaft rotation.
A method of measuring seal slot position comprising:
- inserting an eccentric pin disposed at an end of a tool shaft into the seal slot and positioning the pin so that it bears against a side of the slot;
- rotating the tool shaft via a disk;
- and
- measuring the seal slot position based on an amount of tool shaft rotation by observing a position of gradation markings on the disk relative to a target point.
A tool for measuring turbine nozzle seal slot position, the tool comprising:
- a tool shaft having a longitudinal axis;
- a pin eccentrically disposed at one end of the tool shaft relative to the longitudinal axis, the pin being sized to fit into a nozzle seal slot;
- and
- a disk member disposed at an opposite end of the tool shaft, the disc member facilitating rotation of the tool shaft and pin in the nozzle seal slot, wherein the seal slot position is measured based on an amount of tool shaft rotation.
