Abstract: A clamping element for clamping workpieces in a flexible position. Two slides (2 and 3) guided in parallel slide in cutouts (4 and 5), which are provided in a housing (1). The force for moving the slides is introduced via plunger pistons (9 and 10) by these pistons acting on the front sides (17 and 18) of the slides, whereby a short lever arm is formed between the introduction of the force and the action of the force. A piston (22), which is provided at its head with a wedge (23), is introduced into the housing (1) at right angles to the plane of movement of the slides. This wedge is guided in recesses (6), which are associated with the slides. Due to the piston (22) being pulled down, its wedge is jammed in the recesses (6) of the slides (2 and 3) and the wedge pushes the slides into the cutouts (4 and 5) and fixes same in a self-locking manner.

Abstract: A self-centering element for clamping workpieces via deflecting pins, which act between a drive element and self-centering slides. Deflecting pins, which are provided with grooves in which carrier prisms are arranged, are introduced in pairs into recesses in a housing in a plane located in parallel to the mounting surface of the element. The carrier prisms have wedge surfaces, which are slidingly guided in the grooves of the deflecting pins. The deflecting pins are controlled by pistons, which are arranged in the same plane but at right angles to the deflecting pins. The forces are transmitted beginning from the piston via the deflecting pins to the carrier prisms and then to the self-centering slides, which are connected to the carrier prisms and which move the clamping jaws.

Abstract: A clamping element is provided for clamping work pieces on machine tables and the like with a tiltably mounted clamping lever, which is longitudinally displaceable in the clamping plane. The clamping element includes a housing (1) provided with a fork head (3), in the forks of which holes (4) are provided centrally and into which a king pin (5) each is inserted in a rotatably mounted manner. The king pins (5) are provided with guide pins (6), which have two opposite flattened areas. The clamping lever is a square with two grooves (8) milled in, in opposite locations. The clamping lever (2) can be pushed with its grooves (8) onto the guide pins (6) of the king pins (5) inserted into the fork head (3).

Abstract: A clamping element is provided for clamping workpieces in a flexible position with hydraulically actuated clamping jaws, which can be moved to the workpiece and can be fixed by a clamping insert (2; 30) guided in a housing (1; 29). The clamping insert is provided with an internally located piston (3), which is guided slidingly. Clamping jaws (20; 31) as well as a clamping lever (11), which is connected to the piston via a connecting rod (8) in an articulated manner, are associated with the clamping insert. The clamping operation moves the piston upward and presses the clamping lever onto the workpiece (25). The resistance originating from the workpiece brings about the stopping of the clamping lever and at the same time continues to raise the clamping insert, as a result of which the clamping jaws come into contact with the workpiece under the workpiece and firmly connect the workpiece to the clamping insert.

Abstract: A clamping element is provided for clamping workpieces in a flexible position with hydraulically actuated clamping jaws, which can be moved to the workpiece and can be fixed by a clamping insert (2; 30) guided in a housing (1; 29). The clamping insert is provided with an internally located piston (3), which is guided slidingly. Clamping jaws (20; 31) as well as a clamping lever (11), which is connected to the piston via a connecting rod (8) in an articulated manner, are associated with the clamping insert. The clamping operation moves the piston upward and presses the clamping lever onto the workpiece (25). The resistance originating from the workpiece brings about the stopping of the clamping lever and at the same time continues to raise the clamping insert, as a result of which the clamping jaws come into contact with the workpiece under the workpiece and firmly connect the workpiece to the clamping insert.

Abstract: A clamping tool holds a workpiece in place on a surface, for example in a machine tool, by a clamping bolt (2) which is moved into a workpiece contacting position by a locking piston (6). The bolt (2) and the piston (6) are slidable in respective bores (3, 4) in a housing (1) in which the clamping bolt (2) is locked in a workpiece supporting position by the locking piston (5, 6). For this purpose the locking piston (6) has a piston rod (5) with a wedging incline (8) cooperating with a respective wedging incline (2′) at an inner end of the clamping bolt (2). A tongue and groove combination is provided between the piston rod (5) and the inner end of the clamping bolt to facilitate the cooperation and force transmission between the piston rod (5) and the clamping bolt (2). A self-locking effect holds the locking piston in a working position until the self-locking effect is released.

Abstract: A workpiece support element has a support bolt (2) slideable in a housing bore. A biasing spring (26) moves the bolt into a work piece contacting position. A locking piston (4) is provided with a recess (22) which separates two segments (28) having concavely beveled edges or piston pressure webs or members (17, 18) for locking the support bolt (2) in the housing. The housing bore is provided with a recess (21) to form concavely beveled edges or housing pressure webs or members (19, 20) for contacting the cylindrical surface of the support bolt (2). In the working position the support bolt (2) is locked between the pressure webs (17, 18, 19 and 20) which increase the locking pressure since these surfaces are smaller than the surface area of the piston (4) exposed to the locking pressure. The piston (4) is provided with an elastically deformable bottom so that the piston segments (28) can move slightly outwardly against the wall of the cylinder wall in which the locking piston (4) is held in place.

Abstract: A support element for supporting or holding a work piece on a mounting surface, for example in a machine tool, has a support or pin movably mounted in a housing. The pin is moved into contact with a work piece by an airstream, held in work piece contact by a hydraulic piston, and reset into a starting position by at least one spring, whereby the work piece is contacted gently under a manual throttle control of the airstream, but firmly held in place by hydraulic pressure.

Abstract: A clamping device for holding, for example a work piece in a machine tool, has a housing with a cylindrical bore and a clamping piston with a dead-end cavity axially slidable in the housing. A clamping lever extends through a ball-bushing with an inner end into the dead-end cavity of the piston and with an outer end carrying a clamping head out of the housing. The inner piston end has a first slanted surface that cooperates with a correspondingly slanted second surface rigidly held in the cavity of the piston. A guide and stop pin also rigidly mounted in the piston cavity cooperates with a recess in the clamping lever to guide an axial movement of the lever relative to the piston and to facilitate a pivoting movement of the lever about the center of the ball-bushing, but simultaneously preventing or stopping a relative rotation between the piston and the lever.

Abstract: A centering and clamping device is provided which comprises a plurality of rod elements, a plurality of clamping slides and reversing and non-reversing transmission elements between the rod elements and clamping slides to convert motion of the rod elements into centering and clamping motion of the clamping slides. Each of the rod elements are in engagement with some of the other rod elements whereby movement of one rod element can transmit motion to at least one other rod element. Various arrangements of the rod elements, slides and transmission elements are disclosed to achieve centering and clamping.

Abstract: A power drive and transmission unit for self centering clamps and chucks has a housing with a cylindrical bore and a piston which is rotatably mounted therein and is acted upon by two linear operating, piston cylinder drives to obtain rotation of the rotating piston in one or the opposite direction. Two or three linearly moving central slide elements which are mounted on said housing for obtaining the centering chuck action elements are connected to the rotating piston by means of pins running in oblong slots in order to convert the rotation of the rotating piston into oppositely linear motion of the slide elements, so that they move towards or away from a common center depending on the direction of rotation of the rotating piston.

Abstract: In a mandrel for the coaxial external machining of workpieces with internal toothing, a reception sleeve with an external toothing corresponding to the workpiece toothing and having openings along the clamping length extending only on a portion of the circumference of the reception sleeve is provided wherein the reception sleeve is integral over the entire clamping length. A clamping member is disposed with tangential and radial play in the reception sleeve for engaging the workpiece toothing and is thereby turnable with respect to the reception sleeve by which the internal toothing of the workpiece can be brought to bear against the external toothing of the reception sleeve in a circumferential direction. The ends of the clamping member extend through the openings for engaging the workpiece toothing and circumferential parts of the reception sleeve and the ends of the clamping member alternate. The clamping member is turned between a clamping and an unclamping position by a rod.
