Definitions

  • the invention relates to a rolling tool for smooth rolling cylindrical surfaces with smooth rolling rolls, which roll on a support cone like a planet and are separated from a cage arranged coaxially to the support cone, support cone and cage being rotatable and axially displaceable relative to one another and at least one axially displaceable part in one to a direction of advance of the tool on a threaded nut arranged on a threaded part of a receiving shank provided with a longitudinal groove, which is positively connected via driving elements to an adjusting sleeve arranged coaxially to the shank, a locking sleeve also being provided with an inner bore in which a longitudinal wedge is arranged, which engages in the longitudinal groove of the threaded part of the receiving shaft and wherein the adjusting sleeve is axially displaceable by an amount such that unlocking takes place.
  • Rolling tools of the type described in the introduction are known from DE-PS 1954337 and are used in practice and achieve satisfactory results. Fluctuations in diameter of the nominal diameter of the tools to be machined can be compensated for by adjusting the tool within a reasonable range. This is done by axially displacing the support cone and the cage separating the roller rolls. This results in a corresponding radial movement of the rolling rolls, which are brought to a changed working diameter position. The axial displacement of the axially movable part takes place by changing the position of the mentioned threaded nut arranged on the shaft.
  • the threaded nut has a longitudinal groove on its outer circumference, which cooperates with a corresponding counterpart of an adjusting sleeve that overlaps the threaded nut.
  • the threaded nut is also rotated, thereby changing its axial position. This also changes the axial position of the axially displaceable part, whereby the diameter adjustment is effected.
  • the threaded nut has an end toothing on its rear end.
  • a bushing with corresponding end teeth with at least one tooth, but preferably in a cruciform arrangement four teeth is pushed onto the threaded part of the receiving shaft with corresponding end teeth facing the toothing of the threaded nut.
  • the inner bore of this sleeve has a wedge or a feather key which engages in the longitudinal groove of the threaded part of the receiving shaft.
  • the bush is inserted with its teeth into the teeth of the threaded nut and a lock nut is screwed on from behind the bush, so that the threaded nut and the bush and lock nut each abut against one another so that the threaded nut can no longer be twisted. Since the adjusting sleeve engages in the outer longitudinal groove of the threaded nut, it can of course no longer be turned.
  • the lock nut mentioned must first be loosened and the bushing described must be disengaged with its teeth. Then the threaded nut can be rotated accordingly by turning the adjusting sleeve and the diameter can be adjusted. After the diameter has been set, the bushing with its teeth must be brought back into engagement with the threaded nut and the lock nut must be screwed on.
  • 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 should be reduced.
  • this object is achieved in that the locking bush is arranged in the feed direction in front of the threaded nut and has a plurality of receiving areas for the positively acting driving elements of the adjusting sleeve in the circumferential direction.
  • 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 abutment by the compression spring via a stop collar on the threaded nut.
  • the desired locking position can be automatically retracted by simply releasing the adjusting sleeve from the compression spring described.
  • 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 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 sleeve having a plurality of corresponding longitudinal bores which are arranged 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 rollers 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 is 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.
  • the axially displaceable part 5 has a collar 25, the rear flat surface of which is supported on an axial bearing 10.
  • Axial bearing 10 in turn is supported on the front face of a locking bush 11, the rear face of which in turn abuts the front face of a threaded nut 12.
  • 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 20 of the threaded part 14, whereby an anti-rotation device for the locking bush 11 is achieved.
  • the locking sleeve 11 On the outer peripheral surface, the locking 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 so dimensioned that a longitudinal groove 15 and the longitudinal groove 16 are mutually common by a longitudinal wedge 17 common to both can be held against rotation.
  • the longitudinal wedge 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 for removing the protection against rotation 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.
  • the adjusting sleeve 18 closes with a snap ring 6, which is followed by a stop disk 7 on the inside.
  • 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.
  • 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 axial bearing 10. The spring 8 ensures that in the normal state the stop collar 13 always abuts 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 easily possible to combine the springs 8 and 9 into a spring, which can then take up the arrangement of the spring 9.
  • 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. When 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 to the original position, which is reached after the rear flat surface of the collar 25 has been placed on the thrust 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.
  • the threaded nut 12 changes its axial position on the threaded part 14, which, in cooperation with the components supported by the threaded nut 12, brings about the desired change in diameter of the enveloping circle of the smooth rolling rolls 1.
  • the adjustment sleeve 18 only has to be released. It is then from the force of the spring 8 and if necessary. the spring 9 in the opposite direction to the arrow 26 pushed again, whereby the longitudinal wedge 17 engages again in a longitudinal groove 15 of the locking sleeve 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 concentric to the tool axis, the flange 28 being attached 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 connected to one another, the longitudinal wedge 19 'in the described state ensuring that the three parts mentioned cannot rotate round, at the same time the Thread of the threaded nut 12 '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 back 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 extends 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 rolls 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, engages in a corresponding suitable bore 15' of the locking bush 11 'via the tip of at least one pin 17' and thus the secure locking restores.
