Definitions

  • the invention relates to a rolling tool with a clamping shank and a roller head which is movable radially against a force generated by springs and having a roller carrier secured against unintentional rotation.
  • Rolling tools of the type described above are generally in use in the form of smooth rolling tools and have proven themselves well. You will e.g. used on center lathes for the smooth rolling of turned parts. Depending on requirements, such a tool is manually clamped on the machine support by the operator and, after use, is clamped again due to the significant space requirement. The tools are large, have a relatively large number of individual parts and are expensive to manufacture.
  • the roller head is cushioned by disc springs which are arranged between the roller carrier and the clamping shaft on a guide rod, the guide rod carrying the roller carrier.
  • the guide rod which is mounted in slide bearings and is held by an anti-rotation device and a plate spring clamping device, penetrates the clamping shaft. This is very complex and includes the risk of movement hindrance or blockage, so that it is no longer the springs that determine the rolling force but the rolling force becomes uncontrollable. Because of the size, it is not possible for such tools to remain in the application machines described while this machine is carrying out another work operation, for example in a turret. For this very reason, the use of such tools on so-called. CNC lathes not possible.
  • the invention has for its object to provide a rolling tool of the type described above, which is less constructional, inexpensive to manufacture and can be used on NC or CNC lathes without any problems.
  • the risk of movement impairment should be eliminated.
  • the springs are designed as at least two rod springs arranged at a distance and parallel to one another in the direction of movement, which connect the clamping shaft and the roller carrier directly or via connecting parts connected or connectable to these parts.
  • a tool is characterized by a compact, flat design with few individual parts.
  • a clamping shaft is possible that is individually tailored to the circumstances, e.g. can be adapted to a CNC lathe.
  • An additional straight guide and a separate protection against twisting is not necessary, since the provided bar springs ensure that the smooth rolling roller only moves parallel to itself.
  • the rod spring arrangement described creates a parallelogram which forces the movement mentioned. The fact that the movement of the roller in the direction of the acting rolling force is made possible via the bar spring parallelogram avoids any movement impediment such as is known from the tools of the prior art.
  • the roller carrier and at least one bar spring are formed in one piece.
  • the clamping shaft and at least one bar spring are formed in one piece.
  • This at least partially one-piece design can result in manufacturing advantages and there is also a very secure hold of the bar springs. Nevertheless, the assembly of the individual parts remains easy and it is easy to replace component groups with a rod spring integrally molded thereon to adapt the spring stiffness in the desired manner. Through the one-piece training also reduces the number of items.
  • the connecting parts connected or connectable to the roller carrier and / or the clamping shaft and the associated rod springs are formed in one piece.
  • the bar springs it is also possible to give the bar springs a very firm hold due to the one-piece design and, on the other hand, to replace a whole "spring assembly” or “spring parallelogram” with another one with a different size or spring stiffness, regardless of the roller carrier and clamping shaft.
  • the bar springs are designed as leaf springs. On the one hand, this greatly complies with the one-piece design with regard to the manufacturing possibilities, and leaf springs are also easy to fasten as individual elements on the one hand and, on the other hand, their dimensions are easy to calculate with regard to the desired spring constant.
  • the leaf springs can then have a rectangular cross section. The arrangement is preferably such that the longer leg of the rectangular cross section is perpendicular to the direction of movement or the direction of the rolling force. The stability of the tool can be influenced by varying the length of this leg of the rectangular cross section.
  • At least one strain gauge which reacts to the deformation is provided in the region of components deforming under the action of the rolling force and is connected to a device for registering the rolling force at least. This makes it possible to control the rolling force and, if necessary, to influence it.
  • Figures 1, 2 and 3 show a rolling tool, for example for smooth rolling bores.
  • This rolling tool can be clamped with the clamping shank 1 in a tool carrier (not shown) of a lathe, for example an NC lathe, as well as in a turret head (not shown) of a tip lathe.
  • a rolling roller 2 which is held in a form-fitting manner by a roller cage 3, is pressed with a rolling force F against the surface to be smoothed of a workpiece, not shown.
  • the detachable fastening 6 of the bar springs 5,5 ' permits problem-free replacement of the bar springs 5,5' when they are replaced and in the event that springs with other spring characteristics are to be used.
  • grooves 19 can be provided for receiving the spring ends, which are adapted to the dimensions of the spring ends.
  • FIGS. 11 and 12 show a device similar to the device according to FIGS. 4 and 5.
  • the rod springs 5,5 ' do not have a rectangular cross section here but a round cross section. They are designed as round rods, the ends of which are pressed into corresponding holes in the roller carrier 4 and the clamping shaft 1.
  • a tool according to FIG. 11 is provided with a stop, which prevents an inadmissibly large deflection of the bar springs 5, 5 '.
  • the roller carrier 4 has a simple recess 38 into which a stop piece 39 which is fastened to the clamping shaft or integrally formed therewith protrudes.
  • FIGS. 13 and 14 show an exemplary embodiment very similar to that according to FIGS. 6 and 7.
  • the rod springs 5, 5 ' are formed in one piece as leaf springs
  • these leaf springs 5 and 5' used in pairs in a side-by-side arrangement with a gap 43 in between.
  • the stability in the direction of arrow 44 can hereby be increased significantly without the width of the leaf springs 5 or 5 'being increased. It is only required for Increasing the stability in the direction of arrow 44 to enlarge the gap 43 between the respective leaf springs. This arrangement can also achieve a flatter characteristic curve of the springs used in each case.
  • FIGS. 15 and 16 show an arrangement corresponding to the exemplary embodiment according to FIGS. 13 and 14.
  • the rod springs 5, 5 ' are produced from a layering of thin leaf springs 27.
  • the spring behavior can easily be influenced by simply removing or adding such thin leaf springs 27.
  • the thin leaf springs 27 are separated from one another at their respective fastening ends by spacers 29 interposed therebetween, so that there is the corresponding distance 30 between them.
  • the roller 2 for example by the feed movement of a slide on which the clamping shaft 1 "is fastened, the roller 2 remains somewhat backwards and thereby pivots around the axis 33 and thereby positions itself at an angle to the workpiece rotation axis is just as large as the feed movement of the slide carrying the entire tool. If this feed movement increases or decreases, a different swivel angle of the roller 2 with a correspondingly reduced or increased feed speed is automatically set As a result, forward-moving slides are almost completely relieved of feed forces.
  • FIGS. 21 and 22 show an embodiment which is very close in structure to the device according to FIGS. 17 and 18.
  • the entire device is no longer pivoted, but instead a pivot pin 35 is pivotally mounted in the roller carrier 4 ′′ about the axis 33, which in turn carries the pivot lever 46 on which the roller 2, if required 15 and 16.
  • the rest of the structure can correspond, for example, to that of Figures 15 and 16. If this device (FIGS.
