Definitions

  • the present invention relates to a tool holder for the shrink-attachment of tools having preferably cylindrical shafts or shanks.
  • Tool holders for holding cylindrical shafts or shanks have been known for a long time.
  • They are used to hold lathe, drilling, fretting/reaming, grinding and milling/cutting tools and comprise a shrink lining or chuck that has a tensioning portion with an axial internal bore within which the tool shaft can be attached by means of shrinking.
  • the tensioning portion is expanded via the application of heat, preferably by means of an induction coil, and is cooled down again after the tool shaft has been inserted, thereby forming a torque-resistant connection between the tool shaft and the shrink chuck.
  • this kind of tool holder does not just entail drawbacks in the case of rapid-rotation tools.
  • the influence of the workpiece that is to be machined may cause the tool to be deflected out of the tool-holder axis and bring about vibrations that likewise place limits on machining precision.
  • a tool holder in accordance with the present invention is characterized by a shrink chuck contour course in which the shrink chuck diameter extends, in a discontinuous manner, between a first, front diameter at the shrink chuck head and a second, rear diameter at the shrink chuck base in such a way as to form at least two shrinking lining contour portions.
  • the transition between the first portion and the second portion, in which the diameter rises discontinuously, defines the transition between the shrink chuck head and base.
  • the tool shaft carrier has an axial limit stop that serves to determine the tool shaft's axial position within the carrier, i.e., a limit stop which determines the tool shaft's penetration depth into the shrink chuck.
  • the axial limit stop is arranged such as to receive the tool shaft completely within the shrink chuck head and such that the tool shaft does not partially project into the shrink chuck base.
  • the axial limit stop is intended to be placed at the height of the transition or between this and the front end of the shrink chuck head, and it is not supposed to be placed within the region between the transition and the lower end of the shrink chuck base.
  • this special axial configuration of the axial limit stop relative to the transition creates a particularly beneficial ratio between the reduced-mass shrink chuck head and the more rigid shrink chuck base.
  • the shrink chuck head can be heated easily by means, for example, of an induction coil, the geometry of which does not need to be complicated. Furthermore, this approach enables the shrink chuck head to be heated and expanded as evenly as possible because there are similar wall thicknesses throughout the tensioning portion, thus stopping the tensioning portion from unevenly heating up and expanding.
  • the first portion preferably has a conical contour that runs uniformly between the front end of the shrink chuck head and the transition, and the diameter of this first portion extends towards the transition within an angular range of 1° to 20°, especially 4.5°, relative to the tool holder's longitudinal axis. If the shrink chuck head is lent such a geometrical design, the tool holder is compatible with all conventional shrinkage devices.
  • the extension of the shrink chuck contour diameter can run in a range from abruptly, i.e., 0° in terms of being perpendicular to the tool holder's longitudinal axis, up to 50°. Preference is given to a range from 10° to 40°, with particular preference being given to the transition's extension at 30°.
  • the second portion is preferably adjoined by a third portion which has an essentially cylindrical contour, with the second portion having an essentially conical contour that extends towards the third portion at an angle relative to the longitudinal axis in the range of 1° to 20°, particularly 6° in the case of a tool holder with a hollow shaft coupling, and 8° in the case of a tool holder with a tapered shaft coupling.
  • the contour-related transition between the second and third portions occurs in an essentially constant manner, though discontinuous transitions are possible, too.
  • the base has a standardized contour adjacent to the central member of the tool holder, whereas the region between the third portion and the transition is, on account of the conical contour, reduced additionally in terms of its wall thickness, thereby further reducing the shrink chuck in terms of its mass.
  • the tool holder's susceptibility to vibrations is further reduced as well.
  • the shrink chuck region is advantageous for the shrink chuck region to exhibit a four-section contour course, namely a first portion, a second, essentially cylindrical portion adjoining the transition, followed by a flared third portion, which is in turn adjoined by a fourth, essentially cylindrical portion that adjoins the central member and complies with standardized specifications.
  • the conical contour of the third portion is intended to extend towards the central member at an angle relative to the longitudinal axis of the tool holder in the range of 1° to 20°, especially 6° in the case of a tool holder with a hollow shaft coupling, and 8° in the case of a tool holder with a tapered shaft coupling, with the contour-related transitions between the second and third or the third add fourth portions running in an essentially constant manner, though discontinuous transitions are possible, too.
  • the above four-section contour design permits the shrink chuck base mass to be additionally reduced.
  • the second portion has bores into which counter-balancing members, particularly counter-balancing screws, can be inserted, which members are used to make concentricity possible by preventing the tool holder from exhibiting imbalances.
  • An axial internal bore within the tool holder is advantageously provided for cooling the tool while the workpiece is being machined; this bore supplies a cooling fluid to the tool or to the point where the tool engages with the workpiece.
  • This supply channel preferably has a diameter ranging from 3 mm to 6 mm, thereby still ensuring that the tool holder exhibits sufficiently high rigidity.
  • the cooling fluid supplied through the axial supply channel can be supplied to the point where the tool engages with the workpiece either directly via an axial internal bore through the tool to simultaneously cool the tool from within and/or a plurality of bores is provided in the wall of the shrink chuck head, which bores receive the cooling fluid from the supply channel and guide the fluid next to the tool shaft within the tool holder wall, thus causing the cooling fluid to exit the shrink chuck head next to the tool.
  • the coolant lines can be omitted, too, so as to increase rigidity.
  • FIG. 1 shows a longitudinal sectional view of a preferred embodiment of a tool holder
  • FIG. 2 contains information to explain the tool holder's dimensions in FIG. 1 .
  • the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the invention as orientated in FIG. 1 .
  • the invention may assume various alternative orientations, except where expressly specified to the contrary.
  • the specific devices and processes illustrated in the attached drawings, and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.
  • FIG. 1 represents as a longitudinal section a tool holder 1 that comprises a hollow shaft coupling 2 , a central member 3 and a shrink chuck 4 .
  • the shrink chuck 4 has a shrink chuck base 5 , the lower region of which is adjacent to the central member 3 , and the shrink chuck 4 also has a shrink chuck head 6 .
  • It is very easy to identify the four-part contour course of the shrink chuck 4 which course has a first, conical portion 7 , a second cylindrical portion 8 , a third, conical portion 9 and a fourth, cylindrical portion 10 .
  • These portions 7 , 8 , 9 and 10 connect the essentially rotationally symmetrical contour course of the shrink chuck 4 starting out from a front diameter D 1 of the shrink chuck head 6 and terminating at the rear diameter D 4 of the shrink chuck base 5 .
  • the contour course of the tool holder diameter runs in an essentially even manner within the individual portions 7 , 8 , 9 and 10 and constantly between the portions 8 , 9 and 10 , with the diameter of the shrink chuck 4 increasing continuously starting out from the front diameter D 1 as far as the rear diameter D 4 and remaining essentially constant only within the second and fourth portions 8 and 10 .
  • the diameter increases discontinuously within the transition region 11 , i.e., the contour diameter exhibits a discontinuous course during the transition from the first portion 7 to the second portion 8 .
  • the shrink chuck base 5 has a much larger wall thickness than the shrink chuck head 6 , which makes the shrink chuck head 6 not only look slimmer, but also reduces its mass compared to a shrink chuck head 6 whose contour course runs continuously starting out from the shrink chuck base 5 .
  • the tool holder 1 shown in FIG. 1 exhibits sufficiently high rigidity and complies in particular with standardized specifications that, for example, define the maximum diameter of the fourth portion 10 .
  • the shrink chuck head 6 has a tensioning portion that is characterized by an axial internal bore 12 for receiving the tool shaft.
  • the tool shaft's axial penetration depth into the axial internal bore 12 is determined by an axial limit stop 13 that is designed in the shape of a radial constriction of the internal bore 12 .
  • the axial limit stop 13 the tool shaft is in a gripped state only within the shrink chuck head 6 , but not in the shrink chuck base 5 , thus simplifying and facilitating the shrinkage process considerably.
  • Adjoining the axial limit stop 13 is a supply channel 14 that is likewise designed as an axial internal bore and supplies coolant to the tool shaft that has been shrunk within the bore 12 .
  • the coolant can be fed to the tool head and workpiece either via a coolant channel guided axially within the tool and/or bores (not shown) can be provided within the shrink chuck head 6 , which bores, starting out from the supply channel 14 , guide the coolant within the wall of the shrink chuck head 6 past the tool shaft to the front end of the shrink chuck head 6 . This may, for instance, be brought about by means of two bores that are arranged mirror-symmetrically relative to the longitudinal axis of the tool holder 1 and which run within the first portion 7 next to the tool shaft inside the wall.
  • one or more grooves can be provided within the bore 12 ; designed as depressions, these grooves partially increase the internal diameter of the bore 12 .
  • the bore 12 would consequently not be in direct physical contact with the tool shaft in the region of these grooves, thereby forming cavities in these regions; such cavities beneficially receive any moisture, lubricant etc. adhering to the tool shaft so that hydraulic bearings (or hydromounts), which would impede the complete transmission of torque, could not be formed between the bore 12 and the tool shaft.
  • a plurality of grooves that run, for example, parallel to the axis or radially relative thereto is preferably replaced by a spirally shaped groove.
  • FIG. 2 depicts the tool holder 1 from FIG. 1 again as a longitudinal section, though individual dimensions are defined more precisely.
  • the following tables indicate examples of values for the individual dimensions. These values are all given in mm or in ° for the dimensions , and and are listed as a function of the type of tool holder coupling shaft 2 and the shrink chuck's total length L 4 .
  • Table 1 lists dimensional data for a tool holder 1 having a hollow shaft coupling 2 for a first shrink chuck length L 4 .
  • Table 1 lists dimensional data for a tool holder 1 having a hollow shaft coupling 2 for a first shrink chuck length L 4 .
  • Table 2 lists dimensional data for a tool holder 1 having a hollow shaft coupling 2 for a second shrink chuck length L 4 .
  • Table 3 D1 D2 D3 D4 L1 L2 L3 L4 L5 L6 L7 ⁇ ⁇ ⁇ 6 21 40 50 48.5 60.5 91 110.9 130 38 198.4 30 4.5 8 8 21 40 50 48.5 60.5 91 110.9 130 38 198.4 30 4.5 8 10 24 40 50 55 65.5 91 110.9 130 43 198.4 30 4.5 8 12 24 40 50 55 65.5 91 110.9 130 48 198.4 30 4.5 8 14 27 42 50 60.5 70.5 91 110.9 130 48 198.4 30 4.5 8 16 27 42 50 60.5 70.5 91 110.9 130 51 198.4 30 4.5 8
  • Table 3 lists dimensional data for a tool holder 1 having a tapered shaft coupling (not shown) for a first shrink chuck length L 4 , whereby the shape of the tool holder 1 that has a tapered shaft coupling differs from the shape of a tool holder 1 that has a hollow shaft coupling 2 only in the region of the coupling shaft and central member.
  • Table 4 lists dimensional data for a tool holder 1 having a tapered shaft coupling (not shown) for a second shrink chuck length L 4 .
  • a tool holder 1 in accordance with the present invention is much less prone to vibrations than known tool holders, thereby permitting, inter alia, higher rotational speeds so that the quantity of material that is removed during machining and determined by the tool speed, the tool feed rate and the tool's cutting depth can be increased, thus simultaneously decreasing the machine operating times needed to manufacture a workpiece. Accordingly, a tool holder according to the present invention enables workpieces to be made and machined much more efficiently and with greater economy.
