  • Patent number: 8408528
    Abstract: A clamping device has several clamping element receptacles each with a clamping element held by the clamping element receptacle. The clamping element receptacles have an inclination running obliquely to a clamping direction of the clamping device and by means of which the clamping element is guided. The clamping element has a clamping jaw support and the clamping jaw is connectable to the clamping jaw support. 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.

  • Patent number: 7878070
    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.

  • Publication number: 20100201084
    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.

  • Patent number: 7699321
    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.
