Definitions

  • the invention relates to an impact tool for impact anchors with expansion sleeve according to the preamble of the main claim.
  • Knock-in anchors are known which can be used in drilled holes in masonry and can be positively anchored in an undercut drilled hole by driving an expansion sleeve onto an expansion cone. Such an impact anchor is described in DE-A 36 34 431.
  • impact tools that can be clamped in rotary hammers and impact drills are known. These usually consist of hardened steel sleeves, via which the impact of the impact drill is transferred to the dowel sleeve. It is therefore not necessary to replace the drill after the drilling process or to use a second drill with a hammering tool provided thereon.
  • a disadvantage of the known hammer-in tools is that when the drill is lowered, the hammer-in tool often falls off the drill and must be reattached again if the work process is interrupted several times.
  • the invention has for its object to provide an impact tool that can be firmly locked on the drill.
  • the drill is guided through the plastic sleeve of the driving tool into the adapter part, which is partially overlapped by this sleeve, and firmly locked there in the drill head receptacle of the adapter part.
  • the drill can thus also be lowered with the driving tool located thereon without the need to worry about the driving tool falling off.
  • the adapter part can have on its front side facing the expansion sleeve a taper provided with longitudinal ribs which engage in longitudinal grooves arranged in this area on the front side of the expansion sleeve.
  • a taper provided with longitudinal ribs which engage in longitudinal grooves arranged in this area on the front side of the expansion sleeve.
  • this ring gear engages an annular end face of the anchor shaft of the drive-in anchor, so that the anchor shaft is rotated by rotating the drive-in tool, as a result of which the expansion sleeve of the drive-in anchor is pushed or screwed onto an expansion body.
  • the anchor shaft can no longer be turned, so that the ring gear on the corresponding end face of the anchor shaft rotates.
  • the maximum torque that can be transmitted from the driving tool to the anchor shaft can be higher or lower.
  • the diameter reduction and the longitudinal ribs provided at the end of the adapter part or the sprocket ensure optimal transmission of the impact and the torque of the impact drill ne reached on the impact anchor.
  • the drill can be inserted into the adapter part without any problems until the transition to the smaller diameter and in the area of the transition to the Lock the reduced diameter with the adapter part.
  • the latching is effected in that the drill inserted through the sleeve comes to lie in the transverse groove provided on the inside of the adapter part by means of a rotary movement with the drill plate located on the drill head of the drill shaft, as a result of which the drill is firmly centered in the adapter part.
  • This ensures that the impact of the impact drill can be transmitted to the dowel sleeve without damping.
  • the fixing knobs lying diagonally opposite each other in the end region of this transverse groove meet the drilling dust grooves running out at the drill head of the drill shaft and thus represent a further securing device.
  • the sleeve is made of plastic. Despite the side cutting of the drill bit located in the area of the drill head, it is possible due to the elastic material to insert the drill into the driving tool and center it there. The elasticity of the sleeve also takes into account any bulging of the drill shaft or a collar attached to the drill shaft.
  • the elastic effect of the sleeve can also be achieved in that it consists of metal, but the springs are centered in the drill enable.
  • the impact tool preferably has a tubular adapter part into which a threaded bolt projecting from the impact anchor can protrude during assembly.
  • the adapter part can be designed at its end facing the drive-in anchor as a bolt, which, as explained above, has a diameter reduction and a ring gear or longitudinal ribs.
  • the hammering tool shown in FIG. 1 has an adapter part 1 and a sleeve 2 which partially overlaps it.
  • the sleeve 2 is used to center and thus fix a drill 3, which is shown in sketched form, with its drill head 4 in the adapter part 1, that the drill bit 5 located on the drill head 4 is inserted into a transverse groove (not shown in the drawing).
  • the impact tool placed on the drill 3 strikes the expansion sleeve 6 and transmits the impact of the impact drill to the latter.
  • the best possible transmission of the impact is achieved by the fact that longitudinal ribs 1 a are arranged on the end face of the adapter part 1, which engage in corresponding longitudinal grooves 6 a of the expansion sleeve 6, thereby fixing the adapter part 1 in the expansion sleeve 6.
  • the expansion sleeve 6 is a spreading body 7.
  • the adapter part 1 is shown.
  • fixing knobs 8 which the drilling dust grooves 9 shown in FIG. 1 meet in their outlet area on the drilling head 4.
  • the drill is fixed in the adapter part 1 by snapping the fixing knobs 8 into the drilling dust grooves 9.
  • Longitudinal grooves 1a are arranged on the end face of the adapter part. As already explained for FIG. 1, these serve to better fix the adapter part 1 in the expansion sleeve 6.
  • the adapter part 1 can be seen, which is pierced by a bore 10.
  • a transverse groove 12 is arranged thereon, into which the drilling plate 5 located on the drill head 4 of the drill engages.
  • the fixing knobs engage in the drilling dust grooves 9 running out in this area on the drill head 4 and thus prevent the drill from being set in motion without the adapter part 1 also turning. Since Figure 3 contains a view seen from the sleeve 2, this is also in cut form from the drawing evident.
  • Figure 4 shows the sleeve 2. If this is not made of plastic, the insertion of the drill required elasticity of the sleeve 2 can also be achieved via springs 13 arranged therein.
  • FIG. 5 shows a drive-in tool, the adapter part 1 of which has a reduced outer diameter at its end 15 facing a drive-in anchor 14 and a toothed ring 17 set back from its end face 16.
  • the drive-in anchor 14 has an anchor shaft 18, on the end 20 of which facing away from the expansion body 19 an extension 21 of the inside diameter is provided. This creates at the end 20 a narrow end face 22 on which the ring gear 17 engages during the installation of the impact anchor 14. If the ring gear 17 is pressed against this ring surface 22 with sufficient force and thereby set in rotation by means of an impact drill, the anchor shaft 18 thereby screws onto the threaded bolt 23 of the expansion body 19. As a result, the expansion sleeve 24 is pushed onto the expansion body 19 until it is fully expanded, as shown in FIG. 5. The spreading expansion sleeve 24 engages with its expansion segments 25, 26 in an undercut 27 of a borehole located in a masonry 28. The impact anchor 14 is thus positively anchored in the masonry 28.
  • the adapter part 1 is shown in FIG. 5 as a tubular part, but a part designed as a bolt can also be used, which is provided with a ring gear in a corresponding manner.
