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 protecting a work spindle (2) that is rotatably supported in a spindle head (4A, 4B) of a processing machine and/or a tool (3) clamped in the work spindle (2) from collisions with obstacles in the processing chamber (1) of the processing machine, a plurality of distance sensor modules (6) are arranged on or in a spindle nose (4B) that forms the termination of the spindle head (4A, 4B) toward the processing chamber (1) such that they point toward the processing chamber (1) and are connected to a common signal processing unit (8). When an obstacle is present in a predetermined area of the processing chamber (1), this signal processing unit generates a warning signal based on the measuring signals delivered by the individual distance sensor modules (6). An output (15) of the signal processing unit, at which the warning signal is generated, is connected to the machine control (16) of the processing machine. The distance sensor modules (6) preferably consist of radar or ultrasonic sensor modules.

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).
