Definitions

  • DE 102 19 600 C5 discloses a tool holder having a collet holder in which tool inserts can be used in addition to collets.
  • the tool inserts have a flange plate.
  • the tool insert is bolted to the tool holder via this flange plate.
  • the tool insert is centered by the same conical borehole as the collets are.
  • the collet holder suffers wear from the multiple replacements of the collets. If the tool insert, such as is familiar from DE 102 19 600 C5, is received in the collet holder directly, then the wear on the collet holder increases. The resulting errors in geometry in the collet holder lead to significantly increased errors in the positioning and radial runout of the tool inserts that are inserted into the collet holder. The result is rapid wear on the cutting tools that are received in the tool inserts. When the cutting tools are used in machining, errors can arise in the geometry and surface of the work piece, and damage can occur to the surrounding components of the machine tool and to the tool holder due to the oscillations that can arise.
  • the invention is based on the objective of providing a tool holder that has a collet holder and that can also receive other tool inserts in addition to collets, whereby the replacement of a collet holder by a tool insert, and vice versa, can occur as rapidly as possible.
  • both collets as well as tool inserts according to the invention are designed to be optimally received in the tool holder according to the invention with regard to radial and axial runout.
  • the system according to the invention is based on a tool holder having a collet holder, whereby the collet holder includes a conical borehole and a thread that is disposed coaxially with respect to the conical borehole and that cooperates with a clamping nut.
  • the invention thus provides that means for centering a tool insert are configured in the axial direction between a first end of the conical borehole and the thread.
  • the separate means according to the invention for centering a tool insert can be designed in accordance with the requirements of the tools that are received in the tool inserts. There are significant differences between the tools that are held in a collet and those that are held in a tool insert with respect to rotational speed, machining forces, and the drive torques that are required for the machining.
  • the conical borehole of the collet holder is not designed to be used for the radial and axial receiving of the tool insert, so that wear in the collet holder has no effect on the positional or runout precision of the tool insert. Due to the decoupling of the collet holder from the holder of the tool insert as provided by the invention, wear occurring in the collet holder no longer influences the tool insert, and the resulting errors described above can no longer occur.
  • the means for centering a tool insert can preferably be configured as a short taper, cylinder, and/or a polygon.
  • the short taper can also improve the axial runout of the tool insert in addition to centering the tool insert.
  • the basic principle is that the greater the angle of taper, the more the axial runout of the tool insert will be influenced and improved by the means for centering the tool insert.
  • the designer can also take into account the constraints of every specific application case.
  • the invention provides that the collets and the tool insert are received in the tool holder with the use of various function surfaces, it is possible to optimally take into account the requirements in clamping a tool both using a collet as well as using a tool insert according to the invention.
  • the short taper has an angle of taper of between 60° and 140°, preferably between 90° and 120°.
  • This angular range has proved to be expedient for achieving, on the one hand, an excellent centering of a tool insert for insertion into the tool holder.
  • a very precise axial runout of the tool holder is also achieved.
  • the distribution of the axial clamping force can be adjusted for centering and for achieving a good axial runout. Practical experiments have shown that an angle of taper of between 90° and 120° is optimal. However, in the individual case both smaller and greater angle of tapers may be expedient.
  • the centering means it is also possible to configure the centering means as a polygon connection.
  • the centering it is also possible to transmit high torques, which is particularly advantageous if high cutting forces occur during the machining.
  • the molding element is designed as a conical polygon, then in addition to the radial and axial receiving of the tool holder, a form-locking fit in the rotational direction is also achieved without play.
  • the polygon is designed not as a prismatic polygon connection, whose dimensions are constant in the direction of a rotational axis of the tool holder, but rather as a polygon connection that in the longitudinal cross section of the tool holder has a truncated conical shape.
  • the means according to the invention for centering a tool insert can have three functions, namely centering the tool insert, assuring a good axial runout of the tool insert, and transmitting torque between the tool holder and the tool insert.
  • the result is a very compact design.
  • the weighting of these three functions can be adjusted during the design process by the shape of the polygon, as well as by the dimensions and selection of the angle of taper in accordance with the requirements of the individual case.
  • axial contact can be provided between the thread and the first end of the conical borehole. This is preferably the case if a small angle of taper has been selected, for example smaller than 30°, or if the means for centering the tool insert are cylindrical, because then the axial runout of the tool insert would not be sufficient without supplemental axial contact.
  • the second end of the conical borehole is bounded by a cylindrical segment in the axial direction.
  • This cylindrical segment along with the means for centering a tool insert assures that the radial and axial runout of the tool insert are improved.
  • the means for centering a tool insert are configured as a cylinder or as a short taper with a small angle of taper, then the cylindrical segment according to the invention is advantageous.
  • Both the collets as well as the tool insert according to the invention are advantageously clamped using the same thread of the tool holder, so that ease of servicing results and the installation space requirements of the tool holder are minimized. If two different clamping means are used to clamp the collet and the tool insert, this naturally leads to greater installation space requirements for the tool holder, and ease of operation declines.
  • a second molding element in the form of a planar surface can be assigned both to the short taper as well as to the conical polygon.
  • an additional planar surface is usually employed.
  • an additional planar surface can usually be omitted because the projected planar surface from the conical mold creates sufficient axial support and bending moment stiffness.
  • the molding element is designed as a pure cylinder, then the first molding element takes on exclusively a radial reception. In order also to secure the axial reception of the tool insert within the tool holder, a planar surface must be added to the first molding element as a second molding element.
  • a polygon can also be used in place of the cylinder. As is the case with a cylinder, the pairing with a planar surface is then also necessary if the polygon is prismatic.
  • the thread of the tool holder can be designed as an internal or an external thread. Accordingly, the associated clamping nuts can be designed as having an external or internal thread. In many application cases, conventional clamping nuts can be used.
  • the thread is designed as an internal thread
  • the centering means according to the invention and/or an axial contact are arranged between the short taper and the interior thread
  • the internal thread has a greater diameter than conventional tool holders for clamping nuts.
  • the clamping nuts can be optimized with respect to stability and resistance to stress. As a result, greater clamping forces can be exerted by the clamping nuts on the collets, which results in greater efficiency of the tool holder according to the invention when collets are used.
  • the same also applies if the tool holder according to the invention is combined with a tool insert according to the invention.
  • an increased clamping force is advantageous in order to improve the efficiency of the system composed of tool holder and tool insert with regard to a high-performance tool that is attached to the tool insert.
  • An internal thread that is greater in diameter than conventional internal threads also has the advantage that the gripping surface for a key for activating the clamping nuts is increased, and therefore the application of clamping force by a tool is simplified and made more reliable.
  • the contact surface for such a tool is often arranged on the front end of the clamping nuts, so that a wider annular front end of the clamping nuts has more installation space available in order to make an efficient and reliable transmission of torque possible between key and collet.
  • one length of the conical borehole is so dimensioned that it permits the use of metal-seal collets.
  • metal-seal collets can be obtained on the market and are characterized in that the alternating slots in the collets have a somewhat reduced depth compared to conventional collets.
  • a sufficiently wide bar remains that makes it possible for the collet to reliably seal the conical borehole.
  • a cylindrical segment and/or a carrier segment be configured on the second end of the conical borehole.
  • cylindrical segment As a result of the cylindrical segment, additional improvement in the reception of a tool insert according to the invention is assured with respect to radial and axial runout.
  • the “rear” end of the tool insert is radially fixed within the cylindrical segment, which has a positive influence on the bending stiffness of the connection between the tool insert and the tool holder and consequently on the radial and axial runout of a tool insert according to the invention that has been inserted into the tool holder.
  • the carrier segment In addition to the friction-locking connection between the tool insert and the short taper or the cylinder of the tool holder according to the invention, it is possible through the carrier segment also to achieve form-locking torque transmission, so that even at the highest cutting performances a “slipping” of the tool insert within the tool holder according to the invention is reliably prevented.
  • the segment has at least two, but preferably three or more, axial grooves. These axial grooves to a certain extent are a first part of a splined shaft connection, whereas the other part of the splined shaft connection is formed by corresponding lugs on the tool insert.
  • the contact surfaces are designed to be parallel to the insertion direction of the tool insert.
  • the contact surfaces are shaped in such a way that they no longer run parallel to the insertion direction of the tool insert, but rather a tapering effect is achieved by means of a kind of wedge action.
  • a tapering effect is achieved by means of a kind of wedge action.
  • the carrier segment prefferably configured as a polygon profile.
  • a conventional polygon connection between the tool insert and the tool holder for purposes of transmitting torque can be achieved with all the advantages of this widely known connection.
  • the fine design of the contact surfaces can preferably be executed as a wedge-shaped or a screw-shaped thread. Both fine designs ultimately achieve the result that the tool insert is pulled into the tool holder as a result of the torques.
  • the aforementioned objective for receiving a tool insert in a tool holder in accordance with one of the preceding claims is achieved in that the tool insert has a counterpart surface that cooperates with the means for centering a tool insert that are configured on the tool holder.
  • This counterpart surface may be configured as a pin or as an external cone having a circular cross section or having a polygonal cross section.
  • an axial contact can be provided that cooperates with the planar contact surface of the tool holder.
  • both the centering of the tool insert within the tool holder as well as a good axial runout of the tool insert are achieved.
  • the transmission of torque, as required for the machining process, between tool holder and tool insert is assured independently of the conical borehole. Consequently, the aforementioned function elements, namely the pin and/or if necessary the carrier, can be optimally constructed and designed in accordance with the requirements so that when a tool insert according to the invention is used in the tool holder, a high cutting performance can be realized that produces high-quality surfaces on the machined work pieces.
  • the area of the tool insert between the external cone and the pin and/or the carrier is configured in such a way that the tool insert when installed does not contact the conical borehole of the tool holder.
  • This can be achieved for example by the tool insert having a conical contour in this area, although in the installed state a play of at least 1/10 mm occurs between the conical borehole and the tool insert. This play can be demonstrated simply by applying touch-up paint.
  • the tool insert can be configured as a cylinder in the area between the pin according to the invention and the external cone according to the invention. In this case, the tool insert would become significantly lighter, which can be advantageous at the highest rotational speeds and the highest cutting performances.

  • FIG. 9 depicts the exemplary embodiment according to FIG. 8 showing an inserted tool insert 27 according to FIG. 7 in a cutaway view. It makes clear that lugs 61 of tool insert 27 are located within axial grooves 71 , and contact surfaces 63 of the lugs are located roughly at the level of chamfer 67 .
  • a cutaway view along the line B-B in accordance with FIG. 9 a makes clear that in the rotational direction there is play between axial grooves 71 and lugs 61 .
  • tool insert 37 it is also possible for tool insert 37 to rotate somewhat relative to tool holder 1 before it arrives in its form-locking state. Then contact surfaces 63 make contact with chamfer 67 of tool holder 1 and assure the form-locking transmission of torque between tool holder 1 and tool insert 27 .
  • FIG. 10 a depicts a top view of tool holder 1 with inserted tool insert 27 , and in this top view the sectional plane in accordance with FIGS. 10 b and 9 a is depicted.
  • Tool insert 27 is rotated relative to FIG. 9 a about an angle f 3 with respect to tool holder 9 .
  • left contact surface 63 of lug 61 makes contact on chamfer 67 of tool holder 1 and supports the transmission of torque through the form-locking connection between tool holder 1 and tool insert 27 .
  • contact surface 63 is not arranged parallel to the longitudinal axis, i.e. to the rotational axis of tool holder 1 , but rather for the sake of clarity forms an angle of roughly 5-45° with the rotational axis of tool holder 1 , normal force F N acting upon contact surface 63 has a component in the circumferential direction that facilitates the transmission of torque and a component in axial direction F N,a that pulls tool insert 27 in the axial direction against short taper 5 of tool holder 1 . As a result, the fixing in position of tool insert 27 is improved, and any vibrations or oscillations that may arise between tool holder 1 and tool insert 27 are effectively damped. Because lugs 61 have diagonal contact surfaces 63 on both sides, this effect is achieved regardless of the rotational direction of tool holder 1 .
  • tool holder 1 having a tool insert according to the invention in both clockwise and counterclockwise directions, because there is no danger of clamping nut 43 loosening in response to counterclockwise motion and thus tool insert 27 being no longer held within tool holder 1 .
  • clamping nut 43 is slid onto tool insert 27 from the “tool side.” From the longitudinal cutaway view in FIG. 11 , it is clear that clamping nut 43 is arranged to the left of band 7 . Consequently, slotted ring 35 in FIG. 11 is arranged to the left of clamping nut 43 .
  • This embodiment has the advantage that the clamping force is introduced directly from clamping nut 43 into flange 31 of tool insert 3 .
  • the means for centering tool insert 27 are configured as a conical polygon.
  • the appropriate angle of taper a in this exemplary embodiment is relatively small being roughly 15°, so that conical polygon 73 mainly facilitates the centering of tool insert 27 and the transmitting of torque.
  • FIG. 11 a depicts a cutaway view along the line A-A in FIG. 11 b , from which axial contact 75 and conical polygon 73 can be clearly recognized.
  • FIG. 11 d depicts a view from the left of tool holder 1 without tool insert 27 , from which axial contact 75 and conical polygon 73 can also be clearly recognized.

  • FIG. 11 e depicts an isometric drawing of tool insert 27 in order to clarify the design of this exemplary embodiment of a tool insert 27 according to the invention.
  • counterpart surface 79 with respect to conical polygon 73 of the tool holder can be clearly recognized.
  • only one cylindrical segment 11 is configured on the second end of conical borehole 9 .
  • a carrier segment is not required because conical polygon 73 takes over the transmission of torque.
  • FIG. 11 f depicts a longitudinal cutaway view of tool holder 1 having collet 15 , from which it is clear that collet 15 and tool insert 27 employ identical internal thread 3 , and collet 15 is positioned only by conical borehole 9 .
  • the exemplary embodiment depicted in FIG. 12 substantially corresponds to the exemplary embodiment depicted in FIG. 11 , so that only the differences are discussed below.
  • Clamping nut 43 as in the former exemplary embodiment, is slid from the machine side onto tool insert 27 .
  • Angle of taper ⁇ is relatively large in this exemplary embodiment and is roughly 100°, so that conical polygon 73 , in addition to centering tool insert 27 and transmitting the torque, also assures the axial runout of tool insert 27 . Consequently, axial contact on tool holder 1 and a planar surface on tool insert 27 are not necessary.
  • tool insert 27 makes no contact with conical borehole 9 .
