Definitions

  • the invention relates to a clamping device for clamping an object, for example a workpiece, relative to a base body, for example a clamping table.
  • Clamping devices of the kind relevant here are used, for example, in factories or manufacturing plants, in order to keep a workpiece in a defined position when machining forces are applied to a base body.
  • An example of another location for tensioners is test laboratories such as vibration labs or the like.
  • an injection mold can be clamped on a clamping device on a clamping table.
  • the tensioning device according to the invention can be used in any technical fields of application in which an easily provided and detachable fixation of an object with respect to a base body is of interest, whereby a comprehensive interpretation of the terms “object” and “base body” without a mandatory restriction thereof to "workpieces” and a “(clamping) table” should take place.
  • a base body has a groove with a T-shaped cross-section.
  • One in one Side view simplified as a T-shaped clamping lever has in the free end region of the vertical leg of the T an axle body, which is insertable to form a displaceable in the direction of the longitudinal axis of the T-slot pivot axis in the T-groove.
  • an actuating element formed as a screw, the end face of which is supported in a bottom of the T-slot.
  • the clamping device has a carrier which is firmly connected to the clamping table.
  • a guide shoe is displaceable in the direction of a longitudinal axis in that the carrier has a longitudinal recess, for example a T-groove, in which a T-shaped cross section of the guide shoe is inserted.
  • the guide shoe has a bearing eye with a partially cylindrical lateral surface with a circumferential angle of approximately 180 °.
  • a clamping lever has between an actuator designed as a screw and a contact surface, which is arranged in the actuating element opposite end portion, an axis oriented transversely to the longitudinal axis of the axle body, which is used in the direction of the longitudinal axis in the T-slot of the carrier and the bearing eye such that the axle body is mounted on the lateral surface to form a pivot axis.
  • a position and an orientation of the longitudinal axis can be specified initially on the attachment of the carrier to the clamping table, which is independent bores, threads, recesses and grooves of a chuck table.
  • Another degree of freedom in the direction of the longitudinal axis is given by the longitudinal displaceability of the guide shoe relative to the carrier, which does not necessarily have to be set for operation of the tensioning device, so that for operation of the tensioning device a simple change of the position of the tensioning lever in the direction of the longitudinal axis under use of the degree of freedom. Furthermore, it is possible, with a correspondingly extended guidance of the guide shoe relative to the carrier, to allow the guide shoe, in particular also the region of the bearing eye, to "project" out of the carrier so that the guide shoe and carrier are "telescopic".
  • the application range of the clamping device on the clamping table can be increased and / or made possible that the distance of the exercise of a clamping force can be increased to a workpiece from the mounting location of the clamping device on the clamping table, which brings improved clamping options with it.
  • the one-, two- or three-part designs may have additional components, such as return springs, bearing body, screws, pins and the like, without falling out of the basic forms explained above. Also possible are additional degrees of freedom between body and clamping lever.
  • the invention has for its object to improve a clamping device with respect to the mounting and clamping options, in particular with regard to the degrees of freedom of the clamping device and / or the support of the clamping forces.
  • the invention finds application for a clamping device of any configuration, ie in particular in one-piece design, two-piece design or three-piece design.
  • the invention is based first of the finding that the three-part design over the one-piece design and two-part design in the aforementioned embodiments has a significant advantage, which consists in the additional degree of freedom between the guide shoe and carrier.
  • the advantage of the additional degree of freedom is "bought" by an additional component in the form of the guide shoe, which is not only additional construction costs, but also for the installation additional effort and due to the associated with the connection between the carrier and guide shoe games also to a certain extent Instability can lead at least during assembly.
  • the invention has recognized that it is possible to equip the carrier with at least one slot into which a screw is inserted, the thus having a degree of freedom in the direction of the extension of the slot. If the carrier is screwed or braced with the base body via the aforementioned screw, a degree of freedom between the carrier and the base body is possible.
  • the aforementioned degree of displacement between carrier and body can actually be present.
  • a bore and a slot are provided on a support, so that basically a translatory degree of freedom between the screw and the carrier on an existing game on the hole between screw and hole is limited.
  • the slot can be used by the arranged in the slot screw can be screwed in different positions along the slot with the body, which for example can be made to adapt to a grid for corresponding receptacles for the screw in the body ,
  • the device according to the invention is advantageous on the one hand for the case that the main body, such as a clamping table, is equipped with a fixed grid for positions of screws.
  • this grid may be predetermined by a plurality of equidistant or arbitrarily distributed over a clamping table tapped holes.
  • the main body has a plurality of T-slots, over which in addition to the guaranteed by the tensioning device and the carrier degrees of freedom at least one further degree of freedom is given.
  • the inventive design of the carrier with a slot for the three-piece design is also advantageous, since this can initially provide the degree of freedom between the guide shoe and carrier cumulatively through the slot.
  • the number of possibilities for the connection between the carrier and body, for example transversely or obliquely to any T-grooves, according to the embodiment of the invention is also increased for the three-part design.
  • both the sliding block and the elongated groove have guide surfaces which are oriented in the direction of a longitudinal axis of the elongated groove.

  • the cross-sectional contour of the sliding block is convex, while the cross-sectional contour of the elongated groove is concave.
  • a power transmission between the sliding block and the carrier is not only about normal and frictional forces, but rather also via a form fit in the transverse direction.
  • a self-centering during the tightening of the screw is ensured on the convex-concave, matching design of the cross-sectional contours, which arranges the sliding block in an exact transverse position predetermined by the cross-sectional contours, in which the aforementioned positive connection is given free of play.

  • the longitudinal force of the screw can be converted in the manner of a "wedging action" to an increased normal force on the slope or a chamfered portion of the convex-concave cross-sectional contour.
  • increased normal force can lead to increased frictional force between the sliding block and the carrier, which can counteract, for example, a displacement of the sliding block in the longitudinal direction of the elongated groove.
