摘要： An apparatus for rapidly changing the top jaws of a power-operated chuck having several jaws which are movably guided in a radial direction in a chuck body. Each chuck jaw is formed by a base jaw, and by a top jaw which is exchangeably mounted on the base jaw. After an arresting mechanism has been released, each top jaw can be removed from its base jaw by a relative movement with respect to the latter. The exchange of the top jaws is effected with the aid of a changing apparatus which can be converted from a rest position into a changing position in front of the chuck. The changing apparatus is provided with guide rails which are adapted to correspond with guide surfaces of the base jaws. At least one top jaw is supported on these guide rails, and can be exchanged for the top jaw presently on the base jaw by being displaced by a pusher, which is provided with engaging elements. In order to avoid expensive drive mechanisms within the changing apparatus, the pushers are driven by a movement which is introduced from the outside into the changing apparatus, with this movement being derived from a movement of a tool, a tool support, or some other driven component of the machine tool or of a workpiece grabbing device associated with this machine tool.

摘要： A jaw chuck for mounting on a spindle in which a chuck body is provided which has chuck jaws radially reciprocable thereon. A piston is reciprocable on the chuck axis and cooperating elements of cam means are provided on the piston and the jaws for positively moving the jaws on the chuck body. A fluid piston is connected by a draw bar to the jaw actuating piston for actuation thereof. The pistons are normally movable within that range in which the cam elements are engaged but can be moved to a position where the cam elements are disengaged to permit the jaw elements to be removed from the chuck body. Detent and safety means are provided for preventing the jaws from coming out of the chuck body except when deliberately removed therefrom.

摘要： A device measures the force occurring on radially inwardly movably guided clamping elements of clamping devices. In order to create, with a simple construction, the ability to place the device directly at the corresponding clamping points of the clamping elements without the clamping elements having to be shifted or turned, there is arranged in fixed position in a housing at least one force pickup of substantially radial alignment which rests at its inner end against the housing and is provided on its outer end with a connection for a replaceable pressure piece. At least one similar pressure piece furthermore can be applied to another place on the housing.

摘要： An apparatus for the adjustment of the tension in rotating gripping devices, which are operable with variable power outputs and follow (hysteresis) distinct tension-characteristics for build-up and withdrawal. In order to make possible a stabilization of the tension which is independent from the rotational speed, a desired value for the tension and an internal tolerance allotment for an upper and a lower desired adjustment value are presupposed in a control apparatus. In the control apparatus a leading regulated quantity is produced digitally for the changing of power outputs. The leading regulated quantity is reduced when the desired value approaches a presupposed amount, so that the actual value in presupposed intervals lessens regularly through the regulated quantity reduction under the desired value and is again increased. By an increase of the actual value to one of the upper tolerance allotment presupposed values, the regulated quantity is lessened as a desired value to the reduction of the tension and overcoming of the hysteresis under allotments of the lower adjusted desired values, until the actual value has fallen to a value between the desired value and the presupposed desired value.

摘要： A rotary chuck having a plurality of clamping elements for clamping a respective workpiece. The clamping elements are interchangeable for adaptation of different dimensions of the workpieces, and can be actuated by a force operation via a direction-changing chuck or drive. At least one of the clamping elements is provided with a tension detector. So that the tension detector can always be ready for measuring, and in order to avoid adulteration or error of the measured values and disturbances during transmission of the measured values due to a changing or displacement of the clamping element part which directly engages the workpiece relative to the drive members thereof, the tension detector is arranged with respect to a component which, as viewed in the direction of the force introduced from the force operation, is located after the direction-changing chuck or drive and ahead of the separating point between that clamping element part which directly engages the workpiece and the drive part for the clamping element part, which drive part remains in place during an exchange of the clamping element part in the chuck.

摘要： A clamping force relates to a clamping-force transducer for rotating clamping devices which has at least two opposite pressure pieces adapted to be placed on the clamping elements of the corresponding clamping device and arranged in a support member, at least one of which pressure pieces acts on a force transducer the measurement values of which are taken from the rotating clamping-force transducer housing via a stationary transfer housing. To adapt the clamping-force transducer simply to clamping devices having a different number of clamping elements and to different clamping diameters without the rigidity of the clamping-force transducer being changed thereby, the pressure pieces are arranged replaceably but fixed on the arms of a multi-arm measurement member, at least one arm of the measurement member being developed as the force transducer. The measurement member preferably has a star shape with six arms, each of which has a connection for a pressure piece. In order to determine the corresponding speed of rotation at the same time as the clamping force, a pulse transmitter for a pulse receiver arranged on the fixed transfer housing is arranged on the rotating clamping-force transducer housing.

摘要： A method for selecting the proper clamping force to be applied by a rotatable chuck against a workpiece of known rigidity comprises the steps of inserting a transducer of known rigidity into a chuck of known rigidity, measuring the clamping force under conditions of a stand-still and rotation to obtain a change in clamping force induced by rotation, and multiplying the change of force by a correction factor involving the foregoing rigidities to obtain a predicted change of clamping force which would be experienced upon insertion of the workpiece in the chuck. The predicted change in clamping force enables an operator to select a sufficient amount of clamping force for safely retaining a workpiece in the chuck during rotation.

摘要： The present invention relates to a power-actuated chuck having a plurality of clamping jaws which are radially guided in a chuck body and are connected, via wedge receivers which extend at an angle to the axis of the chuck and wedge pieces extending into said wedge receivers, to an adjustment member which is axially displaceable in the chuck body and whose operating stroke is limited by form-locking and can be lengthened by turning a ring mounted coaxial to the chuck axis in the chuck body in order to disengage the clamping jaws from the adjustment member. In order to be able to disengage the clamping jaws from the adjustment member by an additional stroke of the latter without additional transmission elements being necessary for this, the ring is developed as a synchronizing ring (6) for controlling at least two stop pins (7) which are mounted in the chuck body (1) and are displaceable into the path of movement of the adjustment member as stops limiting the operating stroke (A) of the adjustment member (4).

摘要： A power-operated chuck with gripping jaws guided radially in a chuck body, each of the jaws being driven by a spur toothing from a drive jaw which is movable radially inside the chuck body. The drive jaws are driven by a chuck piston which is axially movable in the chuck body and operates all the drive jaws in common. Independently of the corresponding gripping jaw, each drive jaw is guided in the radial direction and guided non-displaceably in the tangential direction and fixed in position in the axial direction directly in the chuck body. As a result there occurs an indirect securing of the positive connection between the clamping jaws and driving jaws, which positive connection is directly provided by the spur toothing. The chuck piston which is guided directly in the chuck body can be moved beyond the working stroke into a position in which it is out of engagement with the drive jaws.
