Abstract
A device for measuring a workpiece surface along an X-axis, the measured surface residing generally within an X-Y plane. The measuring device has a ring body supported on a pivot body for pivoting in a limited angular range about a pivot axis spaced from and substantially parallel to the X-axis. The measuring device also has a base fixed in the direction of the Y-axis and a ring body supported on the base for limited movement relative to the base in a direction substantially parallel to the Y-axis. A measurement wheel is rotatable about an axis of rotation defined by the ring body and rolls along the workpiece surface when the workpiece and the measurement device move relative to one another in the direction of the X-axis.
Claims20
In a space having orthogonal X-Y-Z axes, a device (104) for measuring a surface (108) of a workpiece (116) in the direction of said X-axis, the surface (108) residing generally within an X-Y plane, the measuring device (104) comprising:
- a pivot body (150) movable relative to the workpiece surface (108) in the direction of said X-axis;
- a ring body (160) supported for pivoting relative to said pivot body (150) about a pivot axis spaced from and substantially parallel to said X-axis, said pivoting being in a limited angular range;
- a measurement wheel (140) rotatable about an axis of rotation fixed relative to said ring body (160) and having a radius with respect to said axis of rotation, said axis of rotation being:
- within said limited angular range of parallel to said Y-axis, and
- spaced from the workpiece surface (108) in the direction of the Z-axis by substantially said radius of said measurement wheel (140),
- whereby said measurement wheel (140) rolls along the workpiece surface (108) when the workpiece (116) and said pivot body (150) move relative to one another in the direction of said X-axis.
In a space having orthogonal X-Y-Z axes, a device (104) for measuring a surface (108) of a workpiece (116) in the direction of said X-axis, the surface (108) residing generally within in an X-Y plane, the measuring device (104) comprising:
- a base (130) selectively fixed in at least the direction of said Y-axis, the workpiece surface (108) and said base (130) movable relative to one another in the direction of said X-axis;
- a ring body (160) supported for limited movement relative to said base (130) in a direction substantially parallel to said Y-axis;
- and
- a measurement wheel (140) rotatable about an axis of rotation fixed relative to said ring body (160) and having a radius with respect to said axis of rotation, said axis of rotation being spaced from the workpiece surface (108) in the direction of the Z-axis by substantially said radius of said measurement wheel (140) whereby said measurement wheel (140) rolls along the workpiece surface (108) when the workpiece (116) and said base (130) move relative to one another in the direction of said X-axis.
