Abstract:
1. A shape-measuring assembly for a roll grinding machine capable of supporting a workpiece roll in at least two spaced bearings defining the axis of the roll, said shape-measuring assembly configured for measuring the shape of the generally cylindrical surface of the roll mounted in the bearings, said shape-measuring assembly comprising: a movable support frame ( a first arm carriage ( a first arm ( a first fixed sensor probe ( a first rail ( a first positionable sensor carriage ( a first positional sensor probe mounted to the first sensor carriage for sensing the position of the surface of the roll; means for interconnecting the first sensor carriage and the arm carriage such that as the arm is moved by the arm carriage toward the roll axis, the first sensor carriage is automatically moved in a first path toward the roll axis; a second rail ( a second sensor carriage ( a second sensor probe mounted to the second sensor carriage for sensing the position of the surface of the roll; means for interconnecting the second sensor carriage and the arm carriage such that as the arm is moved by the arm carriage toward the roll axis, the second sensor carriage is automatically moved in a second path toward the roll axis; a second arm ( a second fixed sensor probe ( whereby the first fixed, second fixed, first positionable and second positionable sensor probes can determine the position of at least three points on the surface of the roll, thus defining a circle on the surface of the roll including the location of the center of the circle and the diameter of the circle.
