Definitions

  • the invention relates to a tool for insertion into a tool holder for chiselling and / or impact drilling hand tool devices with a clamping shank, which has at least one axially closed locking groove and at least two axially open rotational driving grooves towards the free end of the clamping shaft.
  • the clamping shank of these tools having one or two axially closed locking grooves and one or two rotational driving grooves open axially towards the free end of the clamping shaft.
  • the tool holder which serves to hold these tools, has one or two radially displaceable locking elements, which in the present case are designed in the form of balls. Instead of such balls, it is also known to design the locking elements in the form of rollers. The interaction of these locking elements with the axially closed locking grooves results in a positive connection between the tool and the tool holder. By radially disengaging the locking elements, this positive connection can be canceled so that the tools can be removed from the tool holder.
  • the aforementioned locking grooves, together with the locking elements interacting with them, are not exposed to particularly high stresses, since in operation the tool located in the tool holder is practically floating relative to the locking elements, ie the locking elements cooperate with not to transmit any noteworthy forces to the locking grooves during operation. Only when pulling the tool out of a hole in components are certain axial forces to be transmitted via the locking grooves in cooperation with the locking elements to ensure that the connection between the tool and the tool holder remains.
  • the turning driver grooves which are open towards the free end of the clamping shank, and in which corresponding driver bars of the tool holder engage, are subject to extremely high stress.
  • This high stress is due to the torque to be transmitted from the tool holder to the tool.
  • This torque increases, the larger the diameter of the working area for the tools used.
  • the extraordinarily high torques to be transmitted on the rotary driving grooves cause wear and tear such that the tools fail prematurely. This premature failure in connection with the rotary driving floods can occur significantly before the normal working wear of the working area of the tools.
  • the object of the invention is to create a tool which, particularly in cooperation with a suitable tool holder, ensures wear-free transmission of larger torques.
  • the object is achieved in that at least one longitudinal groove which is open axially to the free end of the clamping shaft is provided, which is arranged in such a way that on the one hand there are unequal distances in circumferential direction from the rotary driving grooves which are adjacent on both sides, and on the other hand that the longitudinal groove and locking groove are in their axial projection below Form a shoulder surface facing away from the rear end face overlap.
  • At least one longitudinal groove open to the free end of the clamping shaft is also available for torque transmission in addition to the rotary driving grooves which are open axially towards the free end of the clamping shaft.
  • the longitudinal groove is arranged in such a way that it neither weakens the clamping shank of the tool nor drastically reduces the surface of the clamping shank used for guiding. Accordingly, no losses with regard to the guidance quality of the tool according to the invention are to be accepted, although the total area of attack that is decisive for the torque transmission is increased considerably.
  • a shoulder surface facing away from the rear end side is formed, which brings about the axial fixing in cooperation with corresponding locking elements of the tool holder. Since no noteworthy forces are to be transmitted in the axial direction, this shoulder surface is completely sufficient for solving the task assigned to it.
  • Two longitudinal grooves are preferably provided, the respective axial projections of which overlap the axial projection of two locking grooves each, forming shoulder surfaces facing away from the rear end face.
  • a weakening of the cross section of the clamping shank is also avoided in particular if the axial projection of the longitudinal grooves is smaller than the axial projection of the locking grooves. Such dimensioning in turn has a positive effect on the formation of the shoulder surface which is decisive for the axial holding of the tool.
  • the flank of the longitudinal grooves expediently runs at least in regions essentially radially.
  • the cross section of the longitudinal groove can be of any design, for example in the form of a trapezoid or a triangle. Since the longitudinal grooves penetrate the locking grooves, it is essential that the locking elements also come into contact with the longitudinal grooves. To avoid that on the Transitions between the longitudinal grooves and locking grooves form edges which promote wear of the locking elements, preferably at least the flank of the longitudinal grooves on the driving side runs in a straight line and forms a tangent to the bottom of the locking grooves, the bottom of the locking grooves being designed in the form of an arc.
  • flank of the longitudinal grooves on the driving side can be convexly curved and the base of the locking grooves can be designed in the form of a circular arc, the arches of longitudinal grooves and locking grooves abutting one another in the overlap region. Even with such a design of the longitudinal groove, deformation cracks which are detrimental to the tool are prevented at most.
  • an optimal design of the longitudinal grooves also lies in the fact that their flank on the driving side is preferably curved concavely and the base of the locking grooves is designed in the form of a circular arc, the arc of longitudinal grooves and locking grooves also overlapping.
  • this configuration of the longitudinal grooves also leads to a clamping shank that looks optically perfect.
  • the tools according to the invention can be produced by cutting or non-cutting, for example by means of extrusion molding.
  • any profile of the clamping shank, including the longitudinal grooves can be produced.
  • non-cutting production for example by means of extrusion, it is preferable to ensure that the flank of the longitudinal grooves opposite the flank on the driving side runs in a straight line and forms a positive opening angle with the axis of symmetry of the locking grooves.
  • flank of the longitudinal grooves opposite the driving-side flank is convexly curved. It makes sense to design the formation of this flank symmetrically to the flank on the driving side.
  • flank of the longitudinal grooves opposite the flank on the driving side is expediently curved. This makes it possible to form both the longitudinal grooves and the tool holder-side, cooperating longitudinal strips as a symmetrical profile if both flanks are concavely curved in the same way.
  • the tool designed in the manner mentioned above has the advantage that it 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 longitudinal grooves remain without function.
  • the advantages according to the invention i.e.
  • the possibility of increasing the torque to be transmitted can be exploited if the tool is inserted into a tool holder with a receiving opening, which expediently has at least one radially displaceable locking element interacting with the axially closed locking grooves, with at least two locking bars which cooperate with the rotary driving grooves which are axially open to the free end of the clamping shaft are provided, and at least one longitudinal bar which cooperates with the longitudinal groove which is open axially to the free end of the clamping shaft, the axial projection of which overlaps the axial projection of the region of the respective locking element which projects into the receiving opening and to the has adjacent carrier strips on both sides which are unevenly spaced in the circumferential direction.
  • the tool holder preferably has two diametrically opposed driver bars, so that the torque to be transmitted is evenly distributed over the tool.
  • two diametrically opposed longitudinal strips are preferably provided. These longitudinal strips are expediently offset with respect to the locking elements in such a way that the axis of symmetry of the longitudinal strips are at an acute angle to the axes of symmetry of the locking elements.
  • a preferred embodiment of the longitudinal strips consists in that at least their flank on the driving side extends in a convex manner.
  • a symmetrical profile of the longitudinal strips brings certain advantages, so that a further preferred embodiment is also distinguished by a convexly curved profile of the flank opposite the flank on the driving side.
  • the arc of both the flank on the entraining side and that of the flank opposite this can essentially correspond to the arc which describes the locking elements, which are preferably designed as balls or cylinders.
  • the tool according to FIGS. 1 and 2 has a clamping shank 1.
  • This clamping shaft 1 is provided with two diametrically opposed rotary driving grooves 2, which are open axially towards the free end of the clamping shaft 1.

  • a longitudinal groove 4 is provided which exceeds the length of the one locking groove 3 on both sides and the axial projection of the longitudinal groove 4 lies within the axial projection of the one locking groove 3.
  • the area of the locking groove 3 which is not overlapped by the axial projection of the longitudinal groove 4 forms a shoulder surface 3b.
  • the cross section of the longitudinal groove 4 is essentially V-shaped, the flank 4a of the longitudinal groove 4 on the driving side extending essentially radially and tangentially to the base of the locking groove 3. 2 also shows how the mouth edge 3a of the locking groove 3 coincides with the mouth edge 4b of the longitudinal groove 4.
  • the tool according to FIGS. 3 and 4 has a clamping shank 5 with two rotational driving grooves 6 which are open axially towards the free end and are diametrically opposite one another. Also diametrically opposite one another, two locking grooves 7 are provided. The length of these locking grooves 7 is traversed by longitudinal grooves 8 likewise arranged diametrically opposite one another with flanks 8a on the driving side. The longitudinal grooves 8 are arranged relative to the locking grooves 7 in such a way that the axial projections of the longitudinal grooves 8 overlap with the axial projections of the locking grooves 7.

As shown in FIG. 4 in particular, in this embodiment the axes of symmetry L of the longitudinal grooves 8 run parallel to the axes of symmetry V of the locking grooves 7.
  • the tool according to FIGS. 5 and 6 has a clamping shaft 9, which is provided with two diametrically opposed rotational driving grooves 10 which are open axially towards the free end of the clamping shaft 9.

As shown in FIG. 6 in particular, the longitudinal grooves 12 essentially have a trapezoidal profile, the axes of symmetry L of the longitudinal grooves 12 being at an acute angle a to the axes of symmetry V of the locking grooves 11.
  • flanks of the longitudinal grooves 12 are selected so that the flanks 12a on the driving side essentially form a tangent to the bottom of the locking grooves 11 and the flanks 12b opposite the flanks 12a on the driving side run parallel to the axis of symmetry V of the locking grooves 11.

  • FIG. 6 shows how the axial projection of the longitudinal grooves 12 lies within the axial projection of the locking grooves 11, so that the non-overlapping regions of the locking grooves 11 form shoulder surfaces 11b.
