  • a carrier is interposed, which is screwed, for example, in any position and orientation with a sliding block of a clamping table. Notwithstanding the one-piece design of the axle body of the clamping lever is not stored in the T-slot of the clamping table, but rather in a T-slot of the carrier. The essential parts of the two-part design are thus the carrier and the clamping lever.
  • 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 one-, two- or three-part designs may have additional components, without falling out of the previously discussed basic designs, such as return springs, bearing body, screws, pins and the like. Also possible are additional degrees of freedom between body and clamping lever.
  • FR 2 463 408 discloses mounting a support body on a chuck table to provide a base for a chuck, wherein the top of the support body is raised from the chuck table.
  • the support body further has a T-shaped stone, with which the clamping device is connected firmly and without degrees of freedom in the direction of a longitudinal axis.

Above this connection region between the guide shoe and the carrier, a single vertical leg is provided which carries in a bore a fixed with a grub screw, designed as axle axle axle body. In the region of the pivot axis of the clamping lever is formed with two parallel, extending in the longitudinal direction of the clamping lever side cheeks, which have recesses for the formation of bearing eyes through which the axle shaft passes.
  • CH 463,244 relates to a clamping device, by means of which not a clamping in a vertical direction of a clamping table is to take place, but rather in a horizontal direction.

  • the carrier provides a contact surface in the area in which the carrier comes into operative connection with the guide shoe.
  • the guide shoe according to the invention is displaceable in the longitudinal direction relative to the carrier, and thus also relative to the main body or clamping table.
  • a shift degree of freedom can be used to provide a further adjustment of the position of a clamping lever for already fixed carrier, for example, a fine adjustment or adaptation to different geometries or processing states of a workpiece to be clamped.
  • an at least temporary fixing of the degree of freedom between the guide shoe and the carrier for example via a screw acting between the guide shoe and the carrier, which can bring about positive engagement or frictional engagement in the region of its end face of the screw.

  • This embodiment of the invention utilizes the knowledge that for a lateral encompassing a good support of the clamping device, in particular against tilting about the longitudinal axis, is given. The reason for this is that in such an embodiment, the mating surfaces have a greater distance from the longitudinal axis than may be the case with support of any T-shaped end portion of the guide shoe according to the above-mentioned prior art, in a T-slot of the wearer intervenes. Thus, acting around the longitudinal axis moments can be better absorbed.

  • the large clamping forces which are guided in the area of the mating surfaces in the guide shoe, cause bending stresses of both the side of the carrier arranged leg and the webs, in the region of which the aforementioned two legs are brought together to the central leg, which carries the axle.
  • a reduced dimensioning, size and a reduced weight of the clamping device can result from the inventive design, which may be due solely to the fact that the aforementioned "diversion" of the clamping force to a central central support leg according to CH 597 976 is avoided, whereby material areas are saved.
