Definitions

  • the invention relates to a clamping tool with a ball head and with a pressure piece receiving the ball head, in which a circumferential groove is provided in which a clamping means for connecting the ball head with the Pressure piece is arranged.
  • the invention is based, so a clamping tool of the type mentioned to design that pressure piece and ball head are easily separable and can not be inadvertently separated from each other.
  • This object is achieved in that as a clamping means elastic O-ring is provided, the inner diameter of which is at least slightly is smaller than the outer diameter of the ball head.
  • the O-ring stops both firmly enough to each other that they do not come apart automatically can.
  • the elasticity of the O-ring ensures that both are relatively easy to separate.
  • the O-ring prevents the penetration of dirt into the receiving opening of the pressure piece is very effective.
  • a particularly advantageous embodiment of the invention is given when the Ball head is arranged at the end of a screw spindle.
  • the pressure pieces are light interchangeable.
  • Ball head is inserted into a sleeve, which in turn can be used in a component.
  • the pressure piece is then placed on the ball head and serves as a press stop for the component.
  • the sleeve is provided with a circumferential collar, with which the sleeve can contact the component, and if the Ball head with its spherical end facing this collar into the sleeve is inserted.
  • the sleeve is supported with its collar on the component and can from Transfer the pressure piece to the component via the ball head.
  • the pressure piece is arranged on a clamping bridge for releasable reception of the ball head.
  • Another advantageous embodiment of the invention is that on the Clamping bridge two ball heads are attached, on which two pressure pieces can be detached are attachable.
  • the spherical head has a spherical head piece and a dowel pin.
  • the ball head is attached to different workpieces with the dowel pin, while the spherical head piece is used to connect to the pressure piece.
  • the dowel pin can be cylindrical as well as conical. With the conical design, it is easier to loosen the respective workpieces given.
  • the dowel pin is provided with longitudinal grooves on its jacket. This gives the dowel a very good hold on the workpiece, but it is still easy to remove from it.
  • FIG. 1 in FIG. 1 denotes a component which is provided with a through hole is in which a sleeve 2 is inserted.
  • a sleeve 2 is inserted in which a sleeve 2 is inserted.
  • this sleeve 2 is a center Ball head 3 used, the head piece freely from the corresponding Section of the sleeve protrudes.
  • the ball head 3 engages in a pressure piece 4, the is provided with a recess adapted to the ball head 3.
  • a circumferential groove is provided in the recess, in which an O-ring 5 is seated.
  • This o-ring 5 is made of elastic material and has an inner diameter that is smaller than the outer diameter of the ball head.
  • the pressure piece 4 is with a Provide collar 6 with which it is supported on component 1.
  • the pressure piece Due to the elasticity of the O-ring, the pressure piece can be easily removed from the ball head 3 be removed and replaced by another. An unintentional There is no fear of separating the two parts.
  • the ball head 3 is one at the end Screw spindle 8 arranged to a screw clamp 9 only indicated heard.
  • a pressure piece 4 sits on the ball head 3, which is again by a O-ring 5 is secured.
  • a pressure piece 14 is provided, which to a Clamping bridge 15 is widened.
  • the pressure piece 14 has an O-ring 5 provided which defines the ball head 3 used and the recess against ensures the penetration of dirt.
  • a normal pressure piece 4 could also be attached to the tension bridge 15.
  • On the underside of the clamping bridge 15 is provided with a plurality of recesses 16, in which ball heads 3 can be used.
  • these are Recesses 16 further recesses 17 are provided, which an oscillation of allow used pressure pieces.
  • FIGs 5 and 7 are different clamping options for one Screw spindle shown with such a clamping bridge 15.
  • Fig.5 shows how the one arm of the clamping bridge can engage in a C-profile 18 and this on one Table 19 sets while the other arm is supported directly on the table 19.
  • Different profiles can be easily removed by loosening the tension bridge replace the ball head of the screw spindle 8.
  • uneven or curved objects 20 can also be used with a define such interchangeable tension bridge.
  • Fig. 7 shows an application in which two components 21 and 22 with one Set single screw spindle 8 on which a clamping bridge 15 is arranged.
  • tension bridges which are more than have two arms.
  • the ball head 3 consists of an actual spherical head piece 31 and a dowel pin 32 connected in one piece with it. With this dowel pin 32, the ball head 3 is fastened to the respective workpiece.
  • the dowel pin 32 can be cylindrical as shown in FIG. 8 or conical as shown in FIG.
  • the dowel pin 32 according to FIGS. 8 and 9 is provided with longitudinal grooves 33, which results in easier connection to the workpiece and also easier release from the workpiece.
