Abstract: A clamping arrangement for fixing workpieces, having a housing with a clamping cone and a clamping segment ring with a plurality of clamping segments. The clamping segments are movable radially relative to one another via joint axial movement relative to the clamping cone. An ejector pin is provided for removal of the clamping segment ring from the clamping cone. A contact region for reception of or contact with a distal end of the ejector pin is provided on an end face of at least one of the clamping segments, which contact region is designed such that the ejector pin restricts outward mobility of the clamping segment in the radial direction in a positive locking manner when the distal end of the ejector pin is arranged in the contact region.

Abstract: A clamping force measuring instrument for a radial clamping device having at least one force sensor for detecting a clamping force of the clamping device and an evaluation device for evaluating sensor data of the force sensor. The clamping force measuring instrument is embodied as a modular clamping force measuring instrument, having an evaluation module a sensor module. The sensor module includes at least one measurement surface and the force sensor. The evaluation module has a radio interface, a memory and/or a display device. The sensor module and the evaluation module are configured for coupling to one another by a coupling device and each has a data connection device. The data connection devices are connected to one another to produce a data connection in the event of the sensor module being coupled to the evaluation module.

Abstract: A changer device for a clamping head having a base and pivoting elements pivotably articulated on the base and which in each case possess at least one engagement portion for impinging clamping jaws of the clamping head with a force. The changer device has a coupling transmission which per pivoting element possesses at least one coupling tab attached so as to be pivotably movable on the respective pivoting element. The changer device has a handle which for the purpose of simultaneous repositioning of the pivoting elements in relation to the base is movable in a relative manner. The handle is locationally fixed in relation to one of the coupling tabs such that a pivoting movement of the handle directly causes pivoting of the coupling tab and indirectly causes pivoting of the further coupling tab such that a pivoting movement of the pivoting elements and the engagement portions is caused.

Abstract: A clamping means in the type of an outer clamping means or an inner clamping means for fixed-clamping of work pieces, for the purpose of rotative processing.

The clamping element is axially fixed to the housing or to the actuation member and engages with at least one clamping segment axially in a form-fit manner in a coupling region between an in axial direction distal guide surface region of the guide surface and an in axial direction proximal guide surface region of the guide surface.

The clamping jaw engages in an undercut provided on the clamping jaw support and is additionally fixed by means of a positive fixing means to the clamping jaw support when it is connected to the clamping jaw support.

Abstract: A chuck body for a clamping chuck for clamping a workpiece has a substantially rotationally symmetrically formed basic body, provided on which is a receiving opening, which is formed as a portion of a cone and is formed for receiving a clamping head in such a way as to transmit force. Attached to the basic body is a deformation sensor, for example as a strain gauge, which is intended and designed for determining a deformation of the basic body in a circumferential direction. In this way, the condition and state of wear of the clamping chuck can be determined.

Abstract: A chuck for accommodating a multipart collet for clamping a workpiece in place has a housing with a collet receptacle having a guide device and guide surfaces. The collet is movable on the chuck in the axial direction. The guide device has balls as rolling elements on the guide surfaces, of which a multiplicity are continuously arranged on a rolling element holder. They are movable together with the latter in the guide device from an initial position into the chuck. A restoring device is provided for the rolling element holder, with a direction of action out of the chuck, in order to move the balls back into the initial position when no collet is in the chuck.

Abstract: A chuck for accommodating a collet chuck, comprising a housing and a chucking tool seat that is assigned to the housing. The chucking tool seat is embedded in the housing as a separate part via an intermediate filling that is made of polymer concrete for connecting the chucking tool seat and the housing. This design has improved properties regarding damping and the total weight while flat sub-areas that are composed of individual guiding plates can additionally be used as clamping areas of the chucking tool seat. Thus a pyramid-type joint is obtained, which could previously be created with the required precision only by using a lot of effort when producing the same from solid material.

Abstract: A vice (11) has two clamping jaws (15) for clamping workpieces. Between the clamping jaws (15), there is a tensioning device (18) for multi-part chuck heads that operates in a downward direction. Both the clamping jaws (15) and the tensioning device (18) are simultaneously activated by means of a single activation device (21, 30, 31, 37), wherein the activation device has two levers (21). On the one hand, these levers are pressed apart at one end, while on the other hand, they have a projection (24) that engages with a coupling pipe (25) for synchronized movement. The coupling pipe (25) is used to activate the tensioning device (18).

Abstract: A replacement device for clamping heads comprises a plurality of clamping jaws and is provided with pivoting parts, which are pivotably mounted on a carrier. The pivoting parts extend essentially in the axial direction of the device and can engage in holes on the clamping jaws. A radially active force applying device pushes the pivoting parts outwards, causing the clamping jaws connected thereto to be pressed together. In this way, the clamping head can be used in a housing or a machine-tool.

Abstract: The invention relates to a clamping device (11) comprising clamping jaws (13) in which a plurality of clamping rods (16) are disposed. The clamping rods (16) are enabled to move by means of an interlinked system of rod chambers (22) and channels (24, 28) in which a magnetorheological fluid (26) is contained. If a magnetic field is applied by means of a magnet (30), the fluid solidifies, the liquid-carrying connection between the rod chambers (22) is interrupted and the rods (16) are fixed in a defined position.

Abstract: A chuck (10) has a chuck body (12), which is provided with three guide devices (24), on each of which is received a radially movable clamping holder (34) for fixing a workpiece to chuck body (12), the guide device (24) being constructed separately from the chuck body (12). Guide device (24) is integrally joined by a polymer concrete filling (46) to the chuck body (12) for a force transfer between guide device (24) and chuck body (12). There is no need for a particularly precise manufacture of the outer contour of guide device (24) and the recess (20) in chuck body (12), because the polymer concrete (46) is able to compensate tolerances.

Abstract: An exchange device for grip heads comprising a plurality of clamping jaws, consisting of a carrier plate having a borehole. Pivoting arms are axially staggered in relation to the carrier plate and are concentrically arranged in relation to the borehole. The pivoting arms are articulated by a joint in such a way that they can be pivoted in a plane containing the axis of the borehole. The pivoting movement is thus carried out radially in relation to the axis of the borehole. Coupling elements are arranged on the pivoting arms, by which the exchange device can be coupled to the clamping jaws of the grip head and detached from the same.
