摘要： In a device for monitoring the position of a tool or machine element on or in a work spindle or tool chuck, in particular, in a machining apparatus, the work spindle or tool chuck has at least one channel that defines a waveguide, which is suitable for propagating electromagnetic waves, that leads from an external surface of the work spindle or tool chuck to the tool or machine element. At least one radar system is provided and arranged outside the work spindle or tool chuck in such a manner that it is capable of irradiating a radar signal from the outer surface into the channel and or receiving a radar signal reflected back from the channel. The radar signal is connected to a signal-processing device that determines a measure of the position of the tool or machine element relative to the work spindle or tool chuck based on at least one radar signal irradiated into the channel and reflected back from the channel.

摘要： In a device for wireless transmission of signals between two parts (17, 23) of a processing machine, wherein, when the processing machine is operating, one of these parts rotates relative to the other part about an axis (18), several antennas (8A, 8B, 8C; 108A, 108B, 108C; 13A, 13B, 13C) are arranged on at least one of the two parts (17, 23) in an at least approximately regular distribution with respect to the peripheral direction of rotation. The antennas (8A, 8B, 8C; 108A, 108B, 108C; 13A, 13B, 13C) are connected in parallel to a transmit device (7) and/or receive device (12) allocated to each part (17, 23). The lengths of the individual antennas (8A, 8B, 8C) overlap in the peripheral direction of rotation, and the antennas are arranged at least partially offset radially and/or in the longitudinal direction of the rotational axis (18). Phase-shifted signals are fed to the individual antennas (108A, 108B, 108C) by the transmit device, and/or signals received by the antennas (13A, 13B, 13C) are superimposed with a phase shift by the receive device.

摘要： In a device for recording deformation of a rotor head of a work spindle, at least one magnet is arranged on a stator or a rotor of the spindle, the magnetic field of which penetrates a measurement section of the rotor head, which is traversed by an axial flow of force during clamping of a tool or tool carrier on the rotor head by a tool clamping device arranged in the rotor. The rotor head has a magnetizability or magnetization that varies in the axial direction in its measurement section, and at least one direction-sensitive magnetic field sensor is arranged on the stator radially opposite the measurement section, which is connected to an evaluation device to determine axial deformation of the rotor head as a function of rotation angle from the strength of the magnetic field as a function of rotation angle recorded by the sensor during one revolution of the rotor.

摘要： A clamping device for clamping a workpiece or a tool or, more specifically, a tool holding fixture in a machine part of a machine tool includes a tension rod slidably mounted within the machine part; a clamping set movable by the tension rod between clamped and released positions; a tension spring dedicated to the tension rod so as to generate the pull-in force of the clamping set; and a release mechanism, by which the clamping set can be moved against the force of the tension spring into the released position by the tension rod. To make possible effective clamping at optimum force, the tension spring is clamped between first and second rod parts of the tension rod. The second rod part can move relative to the first rod part, and, as the clamping set moves into the released position, is compressed on both ends by the release mechanism by moving the two rod parts in opposite directions.

摘要： The subject matter of the present invention relates to a clamping device for clamping a tool or a tool holder (2) in a machine spindle (1), comprising a drawbar (6) that can axially move back and forth between a clamping position and a release position, a clamping spring (18) for actuating the drawbar (6) in the direction of the clamping position, a minimum of one sensor (20) for monitoring the clamping force, and a clamping cone (8) having a plurality of clamping elements (9) that rest against its outside surface, which clamping elements, via the axial movement of the clamping cone (8) by means of the drawbar (6), can be moved back and forth between a clamping position in which the tool or tool holder (2) is retained and a release position in which the tool or tool holder (2) is released. To make possible an easy and reliable transmission of the measured data acquired by the sensor throughout the operating range of the clamping device, a transponder assembly (26, 27) with a stationary stator ring (27) and a rotor ring (26) that can be axially moved by the lifting movement of the drawbar (6) within the stator ring (27) is dedicated to the sensor (20) for the wireless transmission of data and energy.
