Definitions

  • the invention relates to a tool holder according to the preamble of the claim 1.
  • a tool holder of the type mentioned is for example from DE-296 12 795 U1 known.
  • the receiving sleeve of this tool holder has a passage opening, whose extension parallel to the longitudinal axis of the receiving sleeve in is essentially the same size as the length of the Locking element. So that the locking element when inserting a Tool in the tool holder or when removing the tool from the Tool holder can tip freely from the clear width of the receiving opening, the locking ring must support the locking element radially at both Insert as well as when removing the tool against the machining direction in a position releasing the locking element. this happens with the help of those detectable outside the drilling and / or chiseling device, contrary to Machining direction adjustable actuating sleeve, in which the guide ring is stored
  • the invention has for its object to provide a tool holder in the Tool can be used without actuating the actuating sleeve and in which the Actuating sleeve can be moved to a position in which the locking element with little effort releases the tool.
  • the locking element is in the Passage opening displaceable parallel to the longitudinal axis of the receiving sleeve.
  • the one with the Actuating sleeve connected locking element is, for example, at a Removal of the tool from the tool holder together with the Actuating sleeve offset against the machining direction. That way the locking element from the effective range of the guide ring in a Release position and is in this about a perpendicular to the longitudinal axis of the receiving sleeve Aligned swivel axis can be tilted outwards so that it no longer protrudes into the clear width of the mounting hole or into a longitudinal groove of the tool.
  • the locking element has a locking area projecting into the passage opening and one against the machining direction to the locking area adjoining stop area connected to the actuating sleeve on.
  • the locking element move against the processing direction to a release position can, is advantageously the largest, parallel to the longitudinal axis of the receiving sleeve running length of the locking area less than that parallel to the longitudinal axis extension of the through opening of the receiving sleeve.
  • the length of the The locking range suitably corresponds to 0.3 to 0.8 times Extension of the passage opening.
  • the invention is based on a drawing that shows an embodiment explained.
  • the tool holder shown in the locked position is not part of one Chisel device shown and has a receiving sleeve 1 with a central receiving bore 11 into which the insertion end of a drilling or chisel tool 2 protrudes.
  • the receiving sleeve 1 has two diametrically opposite passage openings 12 provided, which extend parallel to the longitudinal axis of the receiving sleeve 1.
  • the receiving sleeve 1 is surrounded by a stop ring 3 and one against the machining direction to the stop ring 3, elastic Damping ring 4 and a guide ring 5.
  • the stop ring 3 is at least in Machining direction axially fixed.
  • the guide ring 5 interacts with two diametrically opposite locking elements 6 together and keeps them a radially inwardly directed stop surface 51 in a locking position in which they pass through the openings 12 of the receiving sleeve 1 and in two each other diametrically opposite, axially closed longitudinal grooves 21 of the tool 2 protrude.
  • Each locking element 6 is composed of one machining-side locking area 61 with the length L1 and one on it adjoining stop area 62. Since the length L1 of the locking area 61 is less than the length of the axially closed longitudinal groove 21 in the tool 2 axially limited displaceable in the locking position of the tool holder. The length L1 of the locking area 61 corresponds approximately to 0.5 times the length L2 of the Passage opening 12.
  • Each locking element 6 is opposite to the machining direction adjoining actuating sleeve 7 in connection and is perpendicular to the Longitudinal axis of the receiving sleeve 1 aligned pivot axis S with respect to Actuating sleeve 7 tiltable.
