Abstract
A manually guided probe of a coordinate measuring device is mounted by two rotary shafts arranged one behind the other and a spring parallelogram for nearly reaction free movement in several spatial directions. The device has a workpiece table that is rotatable and tiltable about at least two shafts.
Claims13
A coordinate measuring device comprising:
- a probe for coordinate measurement,
- said probe being mounted by means of a plurality of rotary shafts arranged one behind the other, to be easily movable in several degrees of freedom,
- a carrier for said plurality of rotary shafts, and
- motor drive means for moving said carrier in a vertical direction
- wherein, said probe is arranged to be manually deflectable in a vertical direction, and
- a workpiece table for supporting a workpiece for measurement by said probe, that is rotatable and tiltable about at least two shafts.

A coordinate measuring device, comprising:
- a probe for coordinate measurement,
- said probe being a rigid probe mounted by means of a plurality of rotary shafts arranged one behind the other, to be easily movable in several degrees of freedom,
- linear guiding means for displacing said rigid probe in a vertical direction, and
- a workpiece table for supporting a workpiece for measurement by said rigid probe, that is rotatable and tiltable about at least two shafts.
1 more element
A coordinate measuring device, comprising:
- a probe for coordinate measurement,
- said probe being mounted by means of two mutually parallel rotary shafts arranged one behind the other to be movable in several degrees of freedom,
- said rotary shafts each having a vertical axis and sensing means for sensing rotary motion of said shafts around said axes,
- said probe being further mounted to be deflectable in a vertical direction,
- a carrier for said rotary shafts,
- motor drive means for moving said carrier in a vertical direction, and
- a control device and sensing means connected to said control device for sensing deflection of said probe,
- whereby deflection of said probe is reset by travel of said carrier driven by said motor drive means.
