摘要： The invention relates to a device for clamping a hollow shaft tool (1) or tool holder provided with a conical hollow shaft (3) in a machine spindle (2) provided with a taper bore (4), especially for use in a machine tool. Said device comprises a clamping sleeve (7), axially displaceable inside the machine spindle (2), a tow-rod (8) for displacing the clamping sleeve (7) and being movable between a release position and a clamping position, and a plurality of pincer elements (19) associated with the clamping sleeve (7). Said pincer elements are radially displaced by the displacement of the clamping sleeve (7) and have clamping faces (21, 24) to be placed on a conical inner surface (22) of the conical hollow shaft (3) and an opposite surface (26) on the work spindle (1). The aim of the invention is to provide a clamping device of the aforementioned kind wherein the hollow shaft tool is reliably retained in the machine spindle even when the tow-bar is already released. For this purpose, the clamping sleeve (7) can be axially displaced relative to the tow-bar (8) and is axially biased by a compression spring (14) against the motion of release of the tow-bar (8).

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： The invention relates to a clamping device for removably mounting a tool (3) or a tool fixture in a receiving part (1). Said clamping device comprises several pincers elements (33) which are concentrically arranged around a central axis (32) within the receiving part (1) and are impinged upon by a tension spring (39) so as to be moved into a clamping position in order to brace the tool (3) or the tool fixture. In order to be able to automatically replace a tool without using much force and energy, an axially movable closing element (17) is assigned to the pincers elements (33). Said closing element (17) impinges the pincers elements (33) in a forward position that is advanced in the direction of the pincers elements (33) for mounting purposes in the clamping position thereof, which is swiveled inward by means of the tension spring (39), while being movable into a retracted position with the aid of a detaching device (12, 16, 45, 46, 47) in order to release the pincers elements (3).

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.
