Abstract: A linked transport mechanism and method that uses a single source of motive force to synchronously position multiple displaceable sensors of a shape-measuring assembly onto a roll received in a roll grinding machine. At least two sensors (28, 29) are mounted on linear slides on at least one measuring arm (1). The complete shape-measuring assembly includes at least three sensors (27, 28, 29) or measuring points to allow the calculation of the cross-sectional shape of the roll and the extraneous error movement of the roll. At least one measuring arm is connected to a linear guide (4) of the frame (3). The linear motor is connected between the frame and the measuring arms. The linked transport mechanism assures the synchronous accurate positioning of the sensors, each at a fixed angle through the roll center, over the entire range of roll diameters that the grinding machine may receive.

Abstract: Disclosed is a caliper assembly for measuring a diameter of a roll received on a roll support of a grinding machine which includes a frame positionable adjacent the roll support and a linear guide connected to the frame. A pair of measuring arms is connected in spaced relation to the linear guide. The linear guide is configured to enable each measuring arm to move relative to the frame and parallel to the longitudinal axis of the linear guide. A linear motor is connected between the frame and the pair of measuring arms. The linear motor is configured to supply to the pair of measuring arms a motive force which causes the pair of measuring arms to move together or apart. If one of the measuring arms contacts a workpiece with a force in excess of a predetermined force, the linear motor terminates supplying motive force thereto.

Abstract: A side-shifting measurement device and method is provided for a grinding machine to measure the diameter of a roll being ground. The device includes a main frame located adjacent the grinding wheel and a side-shifting assembly mounted on the frame. A measuring device is mounted on the side-shifting assembly. The method includes mounting the side-shifting assembly adjacent to the grinding wheel, attaching a measuring device to the side-shifting assembly and contacting the measuring device with the roll such that the measuring device is located on a first side of the grinding wheel with respect to a grinding direction of the invention. When the grinding direction is reversed, the measuring device is laterally shifted from the first side of the grinding wheel to the second side of the grinding wheel.
