  • Patent number: 8585031
    Abstract: A quick-action clamping cylinder is described which has a housing and a cover which covers the housing and has a center opening for receiving a retractable nipple that is arranged on the lower side of a workpiece pallet. The retractable nipple is locked in a spring-loaded manner in the housing by way of a plurality of locking balls that are spring-loaded in the locked position on the outer periphery of the retractable nipple. The locking balls are disengaged from the retractable nipple in the unlocked position by displacing a piston actuated by a pressurized medium. The disclosed examples provide a simple, small clamping system. To this end, the locking balls convert the spring force exerted by the springs into a multiple of the retraction force acting on the retractable nipple, by way of a lever arm transmission.

  • Patent number: 7654285
    Abstract: Disclosed is a high-pressure coupling device for directing media such as oil, water, gases, fats, and similar through quick-change systems. Said high-pressure coupling device comprises a bottom part and a top part. The bottom coupling part is provided with a firmly anchored, stiff valve thorn in the form of a valve screw which creates the sealing effect for delivering the medium along with a spring-loaded slide valve sleeve while the top coupling part is provided with a spring-loaded valve plate that creates the sealing effect for the side of the coupling device, which is to be supplied with high-pressure medium, together with a stiff valve body such that a stiff valve element actuates the spring-loaded valve element of the opposite part in the high-pressure coupling device in a valve-actuating manner when the bottom coupling part and the top coupling part are joined.

  • Patent number: 7520495
    Abstract: The invention describes a rapid-action coupling cylinder comprising a guiding device for the controlled insertion of a pull-in nipple fixed to the underside of a workpiece pallet into the central receiving aperture in the housing of the rapid-action coupling cylinder. In order to ensure that the pull-in nipple is inserted into the central receiving aperture in the housing without damage, provision is made by the invention for the face end of the pull-in nipple to have, in the direction of insertion, a conical bevel that is beveled towards the rear and cooperates with an associated—oppositely beveled—conical receptacle inside the housing of the rapid-action coupling cylinder.

  • Patent number: 6174114
    Abstract: Described is a draw-in nipple for fastening a palette on a machine tool, with the draw-in nipple for fastening of the palette being received by a rapid-action clamping system, with the draw-in nipple being attached afflicted with clearance on the palette and through application of a tension force in its longitudinal direction away from the palette being lockable free of clearance. The draw-in nipple is herein preferably received in a resilient element which upon exertion of a tension force becomes deformed and locked through the draw-in nipple.

  • Patent number: 6139002
    Abstract: Arrangement for clamping and positioning palettes in the correct position, wherein for the clamping of the palettes a draw-in nipple cooperates with a rapid-clamping cylinder. Addtionally, a rotation safeguard is present between the palette and the associated rapid clamping cylinder. This safeguard against rotation is implemented in the form of localizing pins which have a corresponding mechanical strength to prevent movement when clamping force is exerted.
