Patent number: 10408597Abstract: A measuring assembly for measuring the contour of a workpiece has a measuring probe that is pivotably supported and deflectable about a first axis (measuring axis) in order to contact a surface of the workpiece, and has a second axis that is associated with the workpiece. The first axis and the second axis are parallel or approximately parallel to one another for radially contacting a surface of the workpiece. A device for rotating the measuring probe and the workpiece relative to one another is provided, such that the measuring probe contacts the surface of the workpiece during the rotation, and a device for plotting the angular deflection of the measuring probe as a function of the particular rotational position of the workpiece relative to the measuring probe is provided.Type: GrantFiled: April 12, 2017Date of Patent: September 10, 2019Assignee: JENOPTIK Industrial Metrology Germany GmbHInventor: Raimund Volk

Patent number: 9879969Abstract: A roundness and/or dimension measuring device for in-process measurement of crank pins during a machining operation on a grinding machine having a base body, and a measuring head, which is connected to the base body via a rod assembly and which is movable between a neutral position and a measuring position. The measuring head has a measuring probe for contacting the crank pin, and the rod assembly is designed and configured in such a way that the measuring head in the measuring position follows orbital rotations of the crank pin. At least one oscillation damping element is operatively associated with the measuring head for holding it in engagement with the crank pin during the orbital rotation.Type: GrantFiled: December 29, 2015Date of Patent: January 30, 2018Assignee: JENOPTIK Industrial Metrology Germany GmbHInventor: Raimund Volk

Patent number: 6490912Abstract: The invention pertains to a probe for sensing the characteristics of a surface of a workpiece which contains a probe tip that is movably held and prestressed essentially in the direction of the tip (Z-direction) and mounted without play to a first acceleration transducer. The first acceleration transducer transforms the movements of the probe tip and consequently the measurement data into acceleration data, with the first acceleration transducer being movably held and prestressed in the direction of the tip (Z-direction) and fixedly connected to the probe tip. A first integrator performs double integration with respect to time of the acceleration data from the first acceleration transducer, thereby forming longitudinal measurement data which correspond to the features of the sensed surface. The probe is thus able to sense the shape as well as the undulations, or roughness of the surface of a workpiece and outputs the features in the form of a corresponding measurement voltage.Type: GrantFiled: October 26, 2000Date of Patent: December 10, 2002Assignee: Hommelwerke GmbHInventor: Raimund Volk

Patent number: 5444347Abstract: A switching apparatus with an adjusting drive, preferably piezoelectrical, which is connected with a device producing a supply voltage. A second adjusting drive, which is preferably constructed in the same manner as the first adjusting drive, and to which a length measuring device is coupled, which scans the adjusting movement of the adjusting element of the second adjusting drive and produces an output signal, which is connected in a linear manner with the adjusting movement of the adjusting element of the first adjusting drive, is connected with the outlet of the supply voltage producing device. By means of this linear connection, errors which are brought about by hysteresis, drift or temperature in the adjusting drive, which is preferably piezoelectrical, are eliminated.Type: GrantFiled: February 1, 1994Date of Patent: August 22, 1995Assignee: Hommelwerke GmbHInventor: Raimund Volk
