摘要： A method of monitoring a tool clamping device mounted on a machine spindle, the clamping force of which tool clamping device is generated by a spring assembly which exerts a force in the direction of the clamping position on an actuating element actuating the clamping or the release of a tool or tool holder. In the method, the spring force and the displacement of the actuating element are continuously measured during the release and/or clamping of a tool or tool holder and recorded as functions of the time. These recorded functions are used to identify at least one parameter characteristic for the status of the tool clamping device. Based on the spring force and the displacement over time, a spring characteristic curve is plotted in the form of the spring force as a function of displacement, the analysis of which spring characteristic curve provides information about a number of characteristic parameters.

摘要： A clamping device for clamping a workpiece or a tool or a tool holder to a machine component of a machine tool, including an axially movable tension rod, a clamping assembly which can be moved by the tension rod between a clamped position and a released position, a spring assembly dedicated to the tension rod for generating the clamping and draw-in force of the clamping assembly, and a releasing unit by which the clamping assembly can be moved by the tension rod against the force of the spring assembly into the released position. The spring assembly has a minimum of one spring unit with a plurality of flexible spring members disposed between a first and a second spring holder, with the first and second spring holders being secured against torsion relative to the tension rod.

摘要： In the case of a tool clamping device, in particular, for an operating spindle of a processing machine, with an activation element (3) that can be moved by a drive between a first position, in which the tool clamping device is located in a clamped position, and a second position, in which the tool clamping device is located in a released position, a sensor is present in the form of at least one electrical component for detecting a position of the activation element (3). The sensor is integrated structurally into the tool clamping device and at least one section of the activation element (3) directly forms a component of the one or more electrical components, wherein its position influences an electrical property of this component. The component can be an electrical switch whose closed state depends on the position of the activation element (3) in that at least one section of the activation element (3) is electrically conductive and forms a contact electrode of the switch or a part of such an electrode. However, it could also be a capacitor or an inductor.

摘要： A tool or workpiece holder with a receiving body and a clamping device for clamping a tool or a workpiece in a receiving opening of the receiving body. The clamping device comprises a first clamping element, which can be moved in a receiving portion of the receiving body at right angles to a central axis of the receiving opening, and a second clamping element, which can be moved relative to the first clamping element at right angles to the central axis of the receiving opening by means of an actuating element. The second clamping element has conical bottom clamping surfaces on the two clamping elements for inserting the tool or workpiece into the receiving opening. An ejecting mechanism is disposed on the first clamping element for ejecting the tool or workpiece from the receiving opening when the clamping elements are moved into a disengaged position.

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： A clamping device for clamping a workpiece or a tool or a tool holder to a machine component of a machine tool, having an axially movable tension rod, a clamping assembly which can be moved by the tension rod between a clamped position and a released position, a spring assembly dedicated to the tension rod with a plurality of series-connected spring units for generating the clamping and draw-in force of the clamping assembly, and a releasing unit by which the clamping assembly can be moved by the tension rod against the force of the spring assembly into the released position. To ensure the most uniform load possible, the axial spring deflection of the spring units is limited by a stop when the spring assembly is compressed.

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.
