Definitions

  • the invention relates to a tool with a clamping shaft, which is provided for insertion into a tool holder of a handheld power tool intended for percussion drilling with at least two rotary driving grooves, which have diametrically opposite sections and which lead to the axial insertion of rotating drivers of the tool holder into the end face of the clamping shaft, and which has at least one locking recess which is closed for receiving a locking body of the tool holder at least at its end adjacent to the end face of the clamping shank in order to limit axial mobility of the locked tool.
  • Tools of this type are known for example from DE-PS 25 51 125.
  • the invention has for its object to design tools of this type so that they can only be inserted into a tool holder in a very specific angular position.
  • those surfaces of the rotary driving grooves are arranged diametrically opposite one another that are loaded by the corresponding surfaces of the rotating drivers of the tool holder when the tool is driven.
  • the invention also relates to a tool holder for percussion drilling tools with at least two rotary drivers for the axial insertion into rotary driver grooves of tools and with at least one locking body for radial insertion into a locking groove of the tool.
  • the object of the invention is also to design the tool holder in such a way that the tools according to the invention can only be used in a precisely defined position.
  • the clamping shank 11 of a hammer drill shown in FIGS. 1 and 2 has two diametrically opposite locking recesses 12 and, to this end, offset by 90 ° two rotary driving grooves 13 and 14.
  • Both rotary driving grooves 13 and 14 have a substantially same cross-sectional area, however, they differ in that in the rotary driving groove 13 the radially outward opening area is greater than the corresponding opening area of the rotating driving groove 14.
  • the rotating driving groove 14 has a radially measured greater depth than the rotating driving groove 13. The cross sections of the two grooves 13 and 14 are different.
  • the rotary driving grooves 13 and 14 open into the free end face 15 of the clamping shaft, so that the tool shaft can be axially inserted into a tool holder, the strip-shaped rotary drivers 26, 27 adapted to the grooves 13 and 14 (Fig. 8 ) having.
  • the second exemplary embodiment shown in FIG. 3 differs from the first exemplary embodiment in that the bottom 26 of the groove 23 corresponding to the groove 13 is convex and in the exemplary embodiment shown is curved coaxially to the axis of the tool.
  • the third exemplary embodiment shown in FIG. 4 differs from the first exemplary embodiment according to FIGS. 1 and 2 in that only one locking recess 12 is provided here.
  • the fourth exemplary embodiment shown in FIG. 5 differs from the first and third exemplary embodiment according to FIGS. 1, 2 and 4 in that the third locking driving groove 15 is arranged diametrically opposite the single locking recess 12 and has the same cross section as the rotating driving groove 14.
  • a fifth and sixth embodiment are described, which have the common feature that those surfaces of the rotary driving grooves, which are loaded by the corresponding surfaces of the rotary drivers of the tool holder when the tool is driven, are arranged diametrically opposite one another .
  • the two rotary driving grooves 16 and 17 have the same radially outward opening surfaces and their flat side flanks 18 and 22 and 19 and 21 lie in the same diametral planes, so that in any case those surfaces e.g. 18 and 22 are arranged diametrically opposite one another, which are loaded by pressure when the tool is driven by the corresponding surfaces of the rotary drivers of the tool holder.
  • the tool holder which is adapted to the fifth exemplary embodiment of a tool shank, is also suitable for receiving known tool shanks which have diametrically opposed identical rotary driving grooves which correspond to the deeper rotating driving groove 17.
  • FIG. 8 shows a schematic, greatly simplified cross section of a tool holder 25 for the sixth exemplary embodiment according to FIG. 7 of a clamping shank.
  • 7 has two rotary driving grooves 23 and 24 which, like in the previous exemplary embodiments, are trapezoidal in cross section.
  • the tool holder 25 has, for the engagement in the rotary driving grooves 23 and 24, appropriately designed strip-shaped rotary drivers 26 and 27 and locking bodies 30 for the engagement in the locking recesses 12.
  • the flat side flanks 28 and 29, which are loaded by the rotary drivers 26 and 27 when driving the clamping shaft according to FIG. 7, are arranged on a diametral plane of the clamping shaft.
  • the rotary drivers 26 and 27 On the corresponding diametral plane of the tool holder 25, the rotary drivers 26 and 27 have corresponding side flanks 31 and 32.
  • the tool for example a hammer drill
  • the side flanks 28 and 29 of the clamping shank are pressed against the side flanks 31 and 32 of the rotary drivers 26 and 27 by the opposite viewing direction of the cuts charged.
  • the tool holder according to FIG. 8 is designed so that the narrower rotary driver 26 is precisely adapted to the rotary driving groove of a known clamping shaft, which has diametrically opposite, identical rotating driving grooves, then it is ensured that the known clamping shaft, which is not secured against incorrect insertion, does not enter the adapted tool holder 25 can be used.
  • the clamping shank according to FIG. 7 can be inserted into a known tool holder, the second rotary driver of which is indicated by the dashed line 33 in FIG. 8.
  • the locking recesses 12 are arranged offset by 90 ° at least with respect to the one of the diametrically opposite rotary driving grooves 13, 14, 16, 17 and 23.
  • each locking recess is offset by more than 90 ° with respect to the rotary driving groove lagging it in the direction of rotation of the tool. It is thereby achieved that the flank of the rotary driving groove which is loaded by the torque to be transmitted is under pressure from the adjacent locking recess at a greater distance than the other flank of the rotating driving groove from the adjacent locking recess, so that when the tool is driven surfaces of the rotary driving grooves in the tool shank that are subject to pressure are better supported.
  • the convex design of the bottom of the rotary driving groove 26 according to the exemplary embodiment according to FIG. 3 has the advantage that the driver of the tool holder can be made very wide without the cross section of the tool having to be reduced thereby.
  • the design according to the invention has the advantage that clamping shanks This type can be produced with the same devices as the usual known tools, in which the rotary driving grooves are arranged diametrically opposite one another.
  • the rotary driving grooves are trapezoidal in cross-section, as is often the case with the known clamping shanks.
  • the cross sections of the rotary driving grooves can, however, have any shape suitable for a positive rotary connection with the rotating drivers.
