Definitions

  • the invention has for its object to improve a tool of the type described in such a way that a quicker and easier diameter adjustment is possible without loss of setting reliability and at the same time the construction effort is to be reduced.
  • this object is achieved in that at least one locking bush is arranged in the feed direction in front of the threaded nut, which has circumferential receiving areas for the positively acting driving elements of the adjusting sleeve and the inner bore of which has a longitudinal key which engages in the .Longitudinal groove of the threaded part of the receiving shaft, wherein the adjusting sleeve is axially displaceable by at least such an amount that the entrainment elements no longer positively engage in the locking sleeve.
  • the arrangement described makes it possible in the simplest possible way to lock the adjusting sleeve, threaded nut, locking sleeve and threaded part against rotation against one another by mutual engagement via the driving elements described, without the need for a lock nut.
  • the mutual locking is released and the threaded nut can be rotated by simply rotating the adjusting sleeve.
  • the adjustment sleeve is pushed forward again and the lock is restored. All that is required for the adjustment is a short retraction and twisting movement of the adjustment sleeve.
  • the adjustment sleeve is pushed forward again and the set position is locked absolutely reliably. It is not necessary to loosen and tighten lock nuts and the lock nut itself is also superfluous. Face gears can be omitted.
  • an axial bearing is arranged between the axially displaceable part and the locking bush. This minimizes the torsional load on the pawl.
  • Another embodiment of the invention provides that a compression spring is provided in the feed direction in front of the locking bush, which presses the locking bush directly against the threaded nut via displaceable components located in between.
  • the spreading effect of the spring mentioned always ensures correct installation and positioning of the corresponding components.
  • the adjusting sleeve arranged in front of the threaded nut has at least one axially acting compression spring, which is supported on the one hand on the adjusting sleeve and on the other hand on the threaded nut or on such components which are supported by the threaded nut, whereby on the other side of the threaded nut, the adjusting sleeve is held in contact by the compression spring via a stop collar on the threaded nut.
  • This allows the desired locking position after simply releasing the adjusting sleeve from the compression spring itself actively retracted.
  • a deliberate advancement of the adjustment sleeve after the setting has been made can be omitted. The adjustment sleeve only has to be released.
  • Another embodiment of the invention provides that the spring acts on the one hand on the axially displaceable part and on the other hand on the adjusting sleeve.
  • the desired spring load for the adjusting sleeve is achieved on the one hand and, on the other hand, the axially displaceable part is held under spring preload in a manner known per se, so that the tool with its smooth rolling rollers disengages in a known manner during the retraction and after leaving the rolled workpiece surface from the mentioned spring is automatically pushed back to the set working diameter.
  • the spring does both.
  • At least the longitudinal grooves provided on the outer circumference of the locking bush and threaded nut and the associated longitudinal wedge of the adjusting sleeve are designed as external splines and, in the case of threaded nut and adjusting sleeve, as a tooth space and corresponding tooth. This type of training is easy to manufacture and results in favorable engagement conditions.
  • the locking bush, threaded nut and adjusting sleeve can be positively connected to one another by means of at least one axial pin by means of corresponding longitudinal bores, the locking bushing having a plurality of corresponding longitudinal bores distributed in the circumferential direction.
  • This design of the individual elements is particularly favorable for tools for rolling cylindrical outer surfaces.
  • FIGS. 1 and 2 do not differ fundamentally from one another. Only one tool is the kinematic inversion of the other tool. However, there are no fundamental differences between an inner smooth rolling tool and an outer smooth rolling tool of the type shown.
  • An inner smooth rolling tool according to FIG. 1 essentially consists of a holding shank 21, which is followed by a threaded part 14 in the axial direction. Threaded part 14 has a longitudinal groove 20. At the front end of the threaded part 14, a shaft 23 is inserted, the free end of which is designed as a support cone 2.
  • a plurality of smooth rolling rolls 1 are provided, which are supported on the support cone 2 and run around like a planet, and are separated from a cage 3 arranged concentrically with the support cone 2 in the usual and known manner.
  • the cage 3 is connected via a stud 4 to a part 5 which adjoins in the axial direction and is axially displaceable.
  • This axially displaceable part 5 is rotatable on the shaft 23 and axially displaceable relative to the latter;
  • the axially displaceable part 5 has on its rear side an axial bore of such a diameter that the threaded part 14 can be pushed axially into this bore 24.
  • this points axially Liche part 5 has a collar 25, the rear flat surface of which is supported on an axial bearing 10.
  • Thrust bearing 10 in turn, an S is supported on the front end surface 11 from p errbüchse whose rear end face in turn abuts against the front end face of a threaded nut 12th
  • the locking bush 11 is arranged axially displaceably on the threaded part 14 and engages with an inner longitudinal wedge 19 in the longitudinal groove v 20 of the threaded part 14, whereby an anti-rotation device for the locking bush 11 is achieved.
  • the peripheral sleeve 11 has longitudinal grooves 15 in a uniform arrangement.
  • the adjoining threaded nut 12 has at least one longitudinal groove 16 on its outer circumferential side, this longitudinal groove 16 being designed in such dimensions that a longitudinal groove 15 and the longitudinal groove 16 can be held against one another in a rotationally secure manner by a longitudinal wedge 17 common to both.
  • the longitudinal key 17 is arranged on the inside of an adjusting sleeve 18 and engages only a partial amount 22 in the axial direction in the longitudinal groove 15 of the locking bush 11. This already ensures adequate protection against rotation and the axial displacement path to cancel the rotation protection. can be kept small.
  • the adjusting sleeve 18 rests with a rear stop collar 13 on the rear flat surface of the threaded nut 12. In this position, the desired anti-rotation lock is produced and the set diameter position is thereby locked.
  • the adjusting sleeve 18 comprises the structure previously described up to the collar 25 of the axially displaceable part 5. At the front opening, the adjusting sleeve 18 closes with a snap ring 6; which is followed inwardly by a stop disk 7.
  • a spiral compression spring 9 is arranged between the front flat surface of the collar 25 and the rear flat surface of the stop disk 7. Furthermore and concentrically to the spiral compression spring 9, a further spiral compression spring 8 is arranged, which on the one hand also bears against the rear flat surface of the stop disc 7 and. on the other hand is supported on the thrust bearing 10. The spring 8 ensures that in the normal state the stop collar 13 always bears against the rear end face of the threaded nut 12.
  • the spring 9 ensures that, in the normal state, the rear flat surface of the collar 25 is always supported on the thrust bearing 10. All components therefore have a clearly defined position. However, especially with larger tools, it is readily possible to combine the springs 8 and 9 into a spring which can then take up the arrangement of the spring 9. In the exemplary embodiment, the spring 9 ensures that when the tool is withdrawn from the finished bore, the smooth rolling rolls 1 can slide slightly forwards in the direction of a smaller diameter. Once the tool has left the finished bore, the spring 9 presses the axially displaceable part 5 and thus the cage 3 and the smooth rolling rollers 1 back into the original position, which is reached after the rear flat surface of the collar 25 has been in contact with the axial bearing 10.
  • the adjusting sleeve 18 is withdrawn by the amount 22 in the direction of the arrow 26, so that the longitudinal wedge 17 is no longer in engagement with the longitudinal groove 15. However, the longitudinal wedge 17 is still in engagement with the longitudinal groove 16 of the threaded nut 12.
  • this can be rotated, for example, in the direction of arrow 27, which also causes the threaded nut 12 to be rotated accordingly.
  • the threaded nut 12 changes its axial position on the threaded nut 14, in cooperation with the components supported by the threaded nut 12, the desired change in diameter of the enveloping circle of the smooth rolling rollers I is effected.
  • the adjustment sleeve 18 only has to be released. It is then from the force of the spring 6 and if necessary. the spring 9 pushed in the opposite direction to the arrow 26 again, whereby the longitudinal wedge 17 engages again in a longitudinal groove 15 of the locking bush 11, whereby the newly set diameter position is locked.
  • the tool can now be put into operation in the manner known in the prior art.
  • a tool according to FIG. 2 also works in the same way.
  • a tool according to FIG. 2 merely represents the kinematic reversal of a tool according to FIG. 1.
  • some components have therefore been modified to match external machining.
  • the smooth rolling rolls 1 ' run like a planet on a supporting cone 2' which surrounds them on the outside.
  • the support cone 2 ' is supported by a flange 28 concentrically to the tool axis, the flange 28 being fastened to the front end of a threaded nut 12'.
  • the threaded nut 12 ' is arranged on the threaded part 14', which has a longitudinal groove 20 ', the threaded part 14' continuing to the rear as the receiving shaft 21 '.
  • This receiving shaft 21 ' can now be designed in any way and is no longer shown.
  • a locking bush 11' is arranged to be longitudinally displaceable, which engages with a longitudinal wedge 19 'in the longitudinal groove 20' and is thereby secured against rotation.
  • an adjusting sleeve 18' is slidably and rotatably mounted on the receiving shaft 21 'or on the associated threaded part 14'.
  • a snap ring 6' with a stop disk 7 'arranged in front of it is provided on the receiving shaft 21'.
  • a compression spring 29 is arranged between the adjusting sleeve 18 'and the stop disk 7'.
  • the adjusting sleeve 18 ' has at least one axially extending pin 17' which passes through a corresponding longitudinal bore in the threaded nut 12 'and on the other side of the threaded nut 12' in one of a plurality of longitudinal bores 15 'of the locking sleeve 11 which are evenly distributed around the circumference 'intervenes.
  • the adjusting sleeve 18', the threaded nut 12 'and the locking bush 11' are thus connected to one another, the longitudinal key 19 'in the state described ensuring that the three parts mentioned cannot rotate round, at the same time the Thread of the threaded nut 12 1 ensures that at least the threaded nut 12 'cannot move axially.
  • the compression spring 29 ensures that the adjusting sleeve 18 'always bears against the rear of the threaded nut 12'.
  • the spiral compression spring 8 ' ensures that the locking bush 11' is correspondingly positioned on the other side of the threaded nut 12 '.
  • the smooth rolling rolls 1 ' are guided in a suitable and known manner in a cage 3' separating them, which is connected, for example via a stud screw 4 ', to a likewise axially displaceable part 5' which is connected via a collar 25 'on an axial bearing 10' in a manner known per se.
  • a spring 9 ' ensures the necessary contact and the free movement of the smooth rolling rollers 1' in the axial direction during the retraction of the. Tool. This construction is also known per se.
  • the adjusting sleeve 18 ' must be withdrawn by the amount 22' against the force of the compression spring 29 in the direction of the arrow 26, so that a separation from the locking bush 11 'takes place.
  • the adjustment sleeve 18 ' only has to be released so that it is pushed by the compression spring 29 over the tip of at least one pin 17', engages in a corresponding matching bore 15 'of the locking bush 11' and thus the secure locking again manufactures.
