Definitions

  • Open driving grooves with driving surfaces are arranged in the tool shaft axially towards the free end of the clamping shaft. These driving surfaces together as with a strip-shaped rotary driver of the tool holder.
  • the strip-shaped rotary driver is fixed in the tool holder.
  • a quick-change chuck and a tool for a drilling and chiseling device are known.
  • the clamping shank of the tool has two areas arranged one behind the other with a polygonal profile in the form of a hexagon. Between these two areas, the insertion end has a round cross-section, the diameter of which is smaller than the width across flats of the hexagon.
  • the surfaces of both hexagons serve as driving surfaces when transmitting a rotary movement starting from the tool holder to the insertion end of the tool.
  • the invention is therefore based on the object of designing the clamping shank of the tool in such a way that even with a tool with a small working diameter, production can be carried out inexpensively, and the centering of the shank is improved.
  • the object of the invention is achieved in that the polygonal profile is formed with rounded corners, the guide contour of the clamping shaft being formed by the corner dimension of at least two corners, and in that the locking grooves are located in the area of the profile surfaces.
  • a corresponding tool holder is also provided according to claim 8.
  • the tools designed in the manner mentioned above have the advantage that they can be used in a conventional tool holder, for example in accordance with DE-PS 25 51 125. However, this with the loss that higher proportions of torques are not transferable, since the profile surfaces remain without function.
  • the advantages according to the invention i.e.
  • the polygonal surfaces of the square polygon are preferably concave or convex. This creates an enlargement of the polygon areas so that the force transmitted from the tool holder to the clamping shank of the tool is distributed over a larger area. This results in lower surface pressures.
  • the clamping shank 1, 10 shown in FIGS. 1 to 4 has an essentially square cross section with profile surfaces of essentially the same size.
  • locking grooves 2, 19 are arranged, which are closed on both sides in the axial direction.
  • the ends of the locking grooves 2, 19 are each hollow-spherical.
  • the profile surfaces arranged at 90 ° to the locking grooves 2, 19 form driving surfaces 3, 12 which are used for torque transmission.
  • the one for the exact Centering the clamping shank 1, 10 in a tool holder, not shown, necessary guide contour is formed by the corners 4, 5, 6, 7, 13, 14, 15, 16.
  • the profile surfaces arranged at 90 ° to the locking grooves 59 form driving surfaces 52 which are used for torque transmission.
  • the guide contour necessary for the exact centering of the clamping shank 50 in a tool holder is formed by the corners 53, 54, 55, 56.
  • the production of the tool in which the starting product is a press blank to be formed, is also possible for the exemplary embodiments according to FIGS. 1 to 4 and 7 to 12, it being possible for the cross section of the press blank to be round, square, rectangular or polygon-like.
  • a tool holder is shown schematically in FIG. 13, in which the clamping shank 10 of the tool according to FIGS. 3 and 4 is inserted.
  • the tool holder has a guide 60 with a receiving opening, an actuating sleeve 73 and a cage 72 surrounding the actuating sleeve 73.
  • a recess (not shown in the example shown) can be brought into a radial projection of a locking element 67, so that this locking element 67 guided in a passage opening 66 can dodge radially.
  • This means that the locking element 67 can disengage from the locking groove 19 and thereby release the clamping shank 10, so that the tool can be removed from the guide 60 and thus from the tool holder.
  • the receiving cross section of the guide 60 is polygonal and has the same size polygon surfaces 61, 62.
  • the corners 68, 69, 70, 71 of the polygon surfaces 61, 62 are rounded.
