Definitions

  • the invention relates to a centric clamping device according to the preamble of patent claim 1.
  • Centric tensioners usually have a e.g. On a machine table aufspannbaren body, two on the body via longitudinal guides slidably guided clamping jaws and an adjusting spindle for the opposite adjustment of the two jaws on. With the help of the adjusting spindle, the jaws displaceably arranged on the base body can be moved apart and together at the same time, whereby a centric clamping of workpieces is made possible.
  • a generic centric clamping device known. This has a base body, two slidably guided on the base body clamping jaws and rotatably mounted on the base body by means of a spindle bearing adjusting spindle for the opposite adjustment of the two jaws.
  • the spindle bearing is in this known clamping device of a fastened by screws on the main body bearing piece, which contains a cup-shaped bearing web for engagement in an annular groove of the adjusting spindle.
  • U1 discloses a clamping device with a base body and two clamping jaws, which are arranged opposite to each other on the base body and guided along a common axis towards and away from each other adjustable.
  • the DE 10 2013 104 467 A1 discloses a Zentrischspanner in which two mutually adjustable clamping jaws are guided displaceably on a base body.
  • the clamping jaws are adjustable via a rotatably mounted in a central bearing block threaded spindle.
  • the DE 297 23 435 U1 discloses a centric clamping device with two linearly guided against each other movable clamping slide.
  • the adjustment of the clamping carriage is effected by a rotatably mounted within a bearing block threaded spindle having opposite threaded portions at both ends for engagement in threaded nuts of two pistons.
  • a clamping device with a fixedly arranged on a main body first jaw and an adjustable guided on the base second jaw known.
  • the second clamping jaw is adjustable by means of a arranged in a spindle recess of the main body screw.
  • the spindle recess of the base body is covered by a cover element between the two clamping jaws over the entire adjustment range of the clamping jaws.
  • the DE 10 2007 027 808 B3 relates to a clamping device in which the carriers of the clamping jaws are designed as shells enclosing the adjusting spindle.
  • the object of the invention is to provide a centric clamping device of the type mentioned, which contains an optimally protected against contamination spindle bearing with high accuracy.
  • the spindle bearing is housed in a bearing block and has two bearing sleeves axially adjustable within the bearing block. Due to the axial adjustment of the two bearing sleeves not only axial position of the adjusting spindle can be adjusted with respect to the body, via a mutual adjustment of the two bearing sleeves, the spindle bearing can also be biased and adjusted without play. This achieves high precision and good repeatability.
  • the adjusting spindle is completely covered and sealed over the bearing block in the storage area. The centric clamping device is therefore insensitive to chips and the adjusting spindle is protected against contamination in a closed system.
  • the spindle bearing can be designed as a roller bearing with a plurality of rolling elements guided between the bearing sleeves and the adjusting spindle.
  • the adjusting spindle can be used for this purpose, e.g. two spaced-apart annular grooves for internally supporting the e.g. Having trained as balls Wälzköper.
  • the two bearing sleeves may each contain a shoulder-shaped bearing surface for the outside bearing of the Wälzköper at the facing end faces. By mutual clamping of the two bearing sleeves, the shoulder-shaped bearing surfaces can be brought to bear against the balls and thus a possible backlash-free adjustment can be achieved.
  • the spindle bearing could also be designed as a plain bearing with axially adjustable plain bearing sleeves.
  • a simple axial adjustment of the bearing sleeves can be achieved in that the two bearing sleeves each have an external thread for engagement in a corresponding internal thread extending through the bearing block passage opening.
  • the bearing block closed over the entire circumference can be formed integrally with the base body.
  • An optimized chip discharge can be achieved in that passages extending from the recesses between the bearing block and two side cheeks of the main body are arranged to the outside with inclined bottom surfaces.
  • the two clamping jaws can be adjusted via slides displaceably guided in the base body.
  • the slides can be installed in the body so that there is a protected against dirt and insensitive to chips construction.
  • the adjusting spindle expediently has two external threads designed as right-handed or left-handed threads for engagement with corresponding internal threads on through-holes of the two slides.
  • the jaws are preferably releasably secured to the slides. As a result, the jaws can be replaced if necessary and adapted to the respective clamping task.
  • the jaws can have any shape.
  • the in the FIGS. 1 to 4 shown in different views centric clamping device includes a base body 1, on which two clamping jaws 2 and 3 slidably guided via slides 4 and 5 and are adjustable in opposite directions by an adjusting mechanism with an adjusting spindle 6.
  • the base body 1 has two spaced side cheeks 7 and 8 with upper guide surfaces 9 and 10.
