Definitions

  • the invention relates to a hammer tool connection, in particular a hammer drilling tool connection, having the features of the preamble of claim 1.
  • the hammer tool connection in question can be used for hammer drilling tools such as rock twist drills, rock suction drills, rock drill bits, rock cutter bits or the like, which are each suitable for drilling in concrete or reinforced concrete, but also in other masonry, rock or the like .
  • a non-rotating tool such as a hammer chisel is also conceivable as a hammer tool. All of these hammer tools are basically intended for use in connection with a hammer, percussion and/or rotary drilling device.
  • the hammer tool has an insertion section for coupling to the respective drilling device. This is followed by a tool shank, such as a drill shank, and finally a tool head, such as a drill head.
  • BE440648A discloses a hammer tool connection according to the preamble of claim 1.
  • hammer drills in several parts, namely at least with a tool head piece that carries or forms the tool head, and a tool end piece with the insertion section.
  • the totality of these two axially connected hammer tool components forms a hammer tool connection within the meaning of the invention.
  • the advantage of such a tool is that the relatively wear-prone tool head piece, in particular the drill head, can be easily replaced if necessary without having to dispose of the entire tool, especially the tool end piece with the insert section that is not appreciably worn.
  • a further advantage of such a hammer tool connection is that an axial lengthening of the tool shank, ie a so-called column formation, is made possible by one or more intermediate tool pieces being insertable axially between the tool head piece and the tool end piece.
  • Such a structure consisting of a tool head piece, tool intermediate piece or pieces and tool end piece also represents a hammer tool connection within the meaning of the invention.
  • the individual hammer tool components are usually connected via a threaded connection.
  • the tool head is connected to the tool end using a screwing movement. If a column is formed, the tool head piece is connected to an intermediate tool piece via a screwing movement and the intermediate tool piece is also connected to the subsequent hammer tool component, for example the tool end piece or another intermediate tool piece, via a further screwing movement.
  • the two hammer tool components that are connected to one another are in the fully screwed-in state, which is one end position of the two together associated hammer tool components defined, axially to one another via end faces.
  • the impact impulse initially exerted on the end piece of the tool is then ideally transmitted exclusively via the respective axial end faces to the next hammer tool component until it penetrates the rock to be machined via the tool head.
  • the invention is based on the problem of improving the known hammer tool connection in terms of assembly technology.
  • the fundamental consideration is that when a threaded connection is made between two hammer tool components, the user is signaled that a defined end position has been reached by receiving acoustic and, if necessary, haptic feedback when he twists the hammer tool components relative to one another in a screwing-in movement. If the defined end position is not reached, for example due to a certain degree of stiffness in the thread due to increased friction from drilling dust or the like, the user receives no feedback and recognizes that the hammer tool components are not yet optimally connected to one another. The acoustic and, if necessary, haptic feedback is automatically generated mechanically when the hammer tool components are connected to one another via the regular screwing movement. This is very easy for the user, since he does not have to take any additional measures to ensure that the hammer tool components are correctly connected.
  • a tool head piece and a tool end piece or a tool head piece and an intermediate tool piece or an intermediate tool piece and a tool end piece or two intermediate tool pieces are connected to one another in the manner described while generating the acoustic feedback for the user.
  • the hammer tool connection can also have several threaded connections that are based on the connection principle described above, for example for producing a column from hammer tool components. All threaded connections can preferably be produced in the manner described.
  • the meeting elements of the two hammer tool components to be screwed together generate a clicking sound as acoustic feedback.
  • a clicking sound which can be generated in particular by metal elements suddenly hitting one another, is easily perceptible by the user and is also understood intuitively as a signal that indicates that the defined end position has been reached. If the elements meet particularly strongly, the clash of the elements can even be perceived haptically.
  • the two elements that provide the acoustic feedback for reaching the defined end position are further specified.
  • One of the elements is preferably an element designed to be elastic in the radial direction, for example a ring element, in particular a snap ring, ie a ring which is interrupted over its circumference.
  • a ring element in particular a snap ring, ie a ring which is interrupted over its circumference.
  • such an element can be radially expanded when the threaded connection is made by exerting a radial force on it, with the element suddenly deforming back in the direction of its original shape if the radial force suddenly ceases due to its elasticity. i.e. contract radially. This sudden contraction then generates the acoustic feedback when it comes into contact with the other element.
  • the respective other of the elements is in particular a section of the respective other hammer tool component.
  • Claims 6 to 10 describe particularly preferred configurations of the threaded connection and specifically of the two elements which indicate that the defined end position has been reached. It is particularly preferred one of the elements, in particular the snap ring, is guided axially along a run-up slope of the respective other element during the screwing-in movement required to produce the threaded connection, as a result of which the element, in particular the snap ring, expands radially (claim 8).
  • the starting bevel is formed by a radial expansion of the other element or the other hammer tool component, the element suddenly relaxing after it has passed the radial expansion and generating said noise when it hits the surface of the other element. In this position, which the element, in particular the snap ring, then assumes, this can additionally form an anti-twist device, which at least impedes a screwing movement that is opposed to the screwing-in movement.
  • an axial end face of one hammer tool component is in axial contact with an axial end face of the respective other hammer tool component.
  • impact impulses can be transmitted directly via the abutting end faces of the hammer tool components connected to one another, without damaging the respective threads, i.e. the internal thread of one hammer tool component and the external thread of the respective other hammer tool component.
  • Claim 12 defines that the screwing-in movement, which causes said element, in particular the snap ring, to widen over the starting bevel and then suddenly relax again afterwards, is only carried out over a comparatively small angular range.
  • the user must rotate the two hammer tool components by a maximum of 120°, preferably a maximum of 90°, particularly preferably a maximum of 85°, relative to one another in order to generate the acoustic feedback in question, in particular the clicking noise.
  • the small angle range has the advantage that the user does not necessarily have to reach around with his hands during the screwing movement, but can perform the twisting in one continuous movement.
  • Claim 13 defines various preferred variants of the tool head and thus corresponding preferred possible applications of the proposed solution.
  • the tool head can be a drill head of a twist drill or a suction drill, or it can be a drill bit, a milling bit or a chisel head.
  • the corresponding tool head is then part of the tool head piece or forms the tool head piece.
  • the proposed solution is aimed in particular at connecting such a tool head piece to a tool end piece or tool intermediate piece. However, all other connections within a hammer tool are also covered by the proposed solution, in particular the connection between the intermediate tool piece and the end piece of the tool or between two intermediate tool pieces.
  • a hammer tool connection is claimed, which is characterized in that the gap between the respectively connected hammer tool components is covered all around by an annular cover.
  • the gap is preferably sealed by the ring-shaped cover against drilling dust, lubricant or lubricating grease and/or air.
  • the annular cover can optimally protect the threaded connection between two hammer tool components from contamination, as a result of which these hammer tool components can not only be particularly easily dismantled, but can also be optimally reconnected later .
  • the annular cover also creates the possibility of producing a threaded connection between two hammer tool components in such a way that when the hammer tool is used, the impact impulse is not transmitted via the threaded connection, but in particular via the said end faces between the hammer tool components.
  • the ring-shaped cover is an O-ring.
  • the ring-shaped cover in particular the O-ring, covers the gap as soon as the defined end position of the two hammer tool components relative to one another has been reached.
  • the claimed ring-shaped cover can be provided for a hammer tool connection in which, when the threaded connection is made, the achievement of a defined end position of the hammer tool components connected to one another relative to one another is indicated acoustically by two elements of the hammer tool components striking one another abruptly.
  • the hammer tool connection shown in various exemplary embodiments in the drawing is part of a hammer tool that is suitable for working on concrete or reinforced concrete, masonry, rock or the like.
  • the hammer tool In the Figures 1a to c shows the basic structure of a hammer tool. Accordingly, the hammer tool always has a tool head 1, an insertion section 2 and a tool shank 3 lying between them.
  • the tool head 1 can be a drill head or a chisel head.
  • Fig. 1a For example, a drill head of a suction drill is shown while 1c shows a drill bit.
  • the proposed solution also includes other tool heads, for example a drill head of a twist drill, a milling cutter or a chisel head.
  • a drill head of a twist drill for example a drill head of a twist drill, a milling cutter or a chisel head.
  • the shaft 3 then extends from the tool head 1 to the insertion section 2, via which the corresponding hammer tool is coupled to a respective drilling device.
  • the term "drilling device” is to be understood in general terms in this context and includes hammer, percussion and/or rotary drilling devices alike.
  • the drilling device does not necessarily have to transmit a rotary movement to the hammer tool for the intended processing of the rock, but rather, as with a hammer chisel, only a purely linear movement can be transmitted.
  • the respective hammer tool is designed in several parts according to the proposal and accordingly has at least two hammer tool components 4, 5, 6, at least two of which are connected to one another via a threaded connection 7 along a geometric tool axis 8.
  • the hammer tool components connected to one another are selected according to the proposal from the group comprising a tool head piece 4, a tool end piece 5 and an intermediate tool piece 6.
  • the tool head piece 4 is that hammer tool component which carries or forms the tool head 1, for example a drill head of a suction drill ( Fig. 1a ) or a drill bit ( 1c ).
  • the tool end piece 5 is the hammer tool component that has the insertion section 2 for coupling to the respective drilling device carries.
  • the intermediate tool piece 6 is an optional hammer tool component for axial arrangement between a tool head piece 4 and a tool end piece 5 and is used, for example, to lengthen the tool shank 3 and/or to form columns.
  • the tool head piece 4 is connected to the tool end piece 5 via said threaded connection 7 in the simplest case.
  • the tool head piece 4 can also be connected to one or more intermediate tool pieces 6, in which case the connection between the tool head piece 4 and the adjacent tool intermediate piece 6 can also be a threaded connection 7.
  • a threaded connection 7 can also be provided between adjacent intermediate tool pieces 6 .
  • the most distant from the tool head piece 4 intermediate tool piece 6 is like Fig. 1b shows by way of example connected to the tool end piece 5 that has the insertion section 2 . This connection can also be a threaded connection 7 .
  • What is essential in the proposed hammer tool connection is that when one or more of the previously described threaded connections are made, the user is automatically given acoustic feedback if the hammer tool components 4, 5, 6 are correctly connected to one another. Reaching a defined end position of the respectively connected hammer tool components 4, 5, 6 relative to one another is indicated acoustically by two elements 9, 10 of the hammer tool components 4, 5, 6 suddenly hitting one another. The meeting then produces in particular a clicking noise which the user clearly perceives and understands without further ado as a signal that the threaded connection 7 has been optimally established.
  • a suction drill has a central suction channel 11 to, among other things, drill dust, which is produced during rock working, directly above the suction off the drill head.
  • the front end of the suction channel 11 on the drill head side is branched here and preferably several times.
  • the other end of the suction channel 11 opens into a suction attachment, which can be provided in the area of the shank 3 or at the axial end of the tool end piece 5 and via which a suitable suction device, for example an electric vacuum cleaner, can suck off the drill dust.
  • FIG. 2a shows the state before the production of the threaded connection 7,
  • Figure 2b the state after that, when the hammer tool components, here the tool head piece 4 and the intermediate tool piece 6, have reached the defined end position.
  • the elements 9, 10 of these hammer tool components 4, 6 are, on the one hand, an element 9 designed to be elastic in the radial direction in the form of a snap ring 12, and, on the other hand, a section 13 that is groove-shaped here, a so-called end position groove, of the intermediate tool piece 6.
  • these two elements 9, 10, i.e. the snap ring 12 and the groove-shaped section 13, are configured in such a way that they meet radially in order to give the acoustic feedback to the user that a defined end position of the two hammer tool components 4, 6 is reached relative to each other.
  • one element 9, here the snap ring 12 is held axially fixed by the associated hammer tool component, here the tool head piece 4, so that said element 9 cannot move axially relative to the associated hammer tool component 4 when the threaded connection 7 is established.
  • the element 9 in the radial direction, ie orthogonally to the geometric tool axis 8, the element 9 is movable to the extent that it can be expanded radially. The element 9 or the snap ring 12 can thus be pushed apart in the radial direction. This happens automatically during the screwing-in movement that is carried out to produce the threaded connection 7 .
  • the screwing movement involves a screwing movement of the two hammer tool components to be connected, here the tool head piece 4 and the intermediate tool piece 6, relative to each other in the direction of the defined end position.
  • the element 9 or the snap ring 12 Because the element 9 or the snap ring 12 is now guided along the radially outwardly increasing starting bevel 14 of the radial expansion 15, the element 9 or the snap ring 12 automatically expands in the radial direction. As the screwing-in movement continues, the element 9 or the snap ring 12 passes the radial expansion 15 and then contracts again radially due to the elimination of the force that caused the radial expansion, with the element 9 or the snap ring 12 relaxing partially or completely. and hits the surface of the hammer tool component 6 abruptly. The abrupt impact here and preferably causes the clicking noise, which indicates to the user that the two hammer tool components 4, 6 have now reached the defined end position.
  • said surface on which the element 9 or the snap ring 12 strikes after passing the radial extension 15 is associated with an end position groove 13 which is arranged circumferentially, in particular circularly circumferentially, on the hammer tool component 6 .
  • the element 9 or the snap ring 12 is in its final position, here in the end position groove 13, after passing the radial expansion 15, an anti-rotation device 16 is automatically generated, which prevents the two hammer tool components 4, 6 from rotating against the screwing-in movement difficult.
  • the element 9 or the snap ring 12 is arranged in the end position groove 13 in such a way that the user has to exert significantly more force in order to unscrew the two hammer tool components 4, 6 from their end position. In other words, the element 9 or the snap ring 12 allows the two hammer tool components 4, 6 to be twisted out of the end position only with an increased torque compared to the screwing-in movement.
  • the two hammer tool components here the tool head piece 4 and the tool intermediate piece 6, are particularly preferred, while the element 9 or the snap ring 12 is moved axially from the beginning of the run-on bevel 14 to its end position or to the end position groove 13, over an angle of maximum 120°, preferably by a maximum of 90°, particularly preferably by a maximum of 85°, more preferably by a maximum of 80°, relative to one another.
  • a hammer tool connection in particular a hammer drilling tool connection, comprising at least two hammer tool components 4, 5, 6 connected to one another via a threaded connection 7 along a geometric tool axis 8, the hammer tool components 4, 5, 6 respectively connected to one another being selected from the group comprising a tool head piece 4 with a tool head 1, a tool end piece 5 with an insertion section 2 and an intermediate tool piece 6 for the axial arrangement between a tool head piece 4 and a tool end piece 5, the gap between the respectively connected hammer tool components 4, 5, 6 being surrounded by an annular cover 19 covered.
  • the hammer tool connection is designed as explained above.
  • the hammer tool connection also includes the two previously described elements 9, 10 which, when the threaded connection 7 is made, acoustically indicate that the two hammer tool components have reached the defined end position relative to one another by abruptly meeting one another.
  • the ring-shaped cover 19 which differs in particular from the element 9 or 12 that suddenly hits the other element 10 in the defined end position, has the advantage that contamination, which occurs when a corresponding hammer tool is used as intended, does not reach the area of the engaged threads of the respective hammer tool components.
  • the gap is also sealed outwards by the annular cover 19 against drilling dust.
  • the sealing by the annular cover 19 also prevents the lubricating grease with which the threads of the threaded connection 7 are lubricated and/or air, which flows through the tool head piece 4 during suction, from escaping to the outside.
  • the ring-shaped cover 19 is also shown in FIG 2 shown. This is an O-ring 20 which rests under axial and/or radial tension on the two hammer tool components connected to one another, here the tool head piece 4 and the tool intermediate piece 6 .
  • the ring-shaped cover 19 is arranged in an axially fixed manner on one of the two hammer tool components, here the intermediate tool piece 6, in such a way that the ring-shaped cover 19 covers and in particular seals the gap 21 precisely when the defined end position of the respectively connected hammer tool components 4 , 6 is reached. It is, as in particular the right detail of Figure 2b shows the annular cover 19 in sections outside the two interconnected hammer tool components 4, 6.
