Definitions

  • the present invention relates to a tool holder for a handheld power tool with a rotating and / or striking drive, the tool holder having a base body with means for receiving a tool with a groove shaft, the base body being equipped with at least one locking mechanism with which the tool can be locked in the base body , and an actuating element for unlocking the tool is provided.
  • Such a tool holder is such. B. from DE 197 24 532 AI or the unpublished German application 100 02 749.0 known.
  • the base body has a receiving bore into which the corresponding tool with its shaft is inserted and can be fixed therein by means of a locking device.
  • So-called rotary driving webs are arranged in the receiving bore of the base body, which engage in grooves which are open at the end of the tool shank, in order to ensure rotary driving of the tool.
  • the Rotary drive bars in the mounting hole of the base body are usually produced by broaching or hammering.
  • the invention is therefore based on the object of specifying a tool holder of the type mentioned at the outset, which is designed such that it can be produced on the one hand with the least possible outlay and on the other hand the wear occurring therein is as small as possible.
  • a receiving sleeve is used, which is made of a harder material than the base body. This measure makes it possible to manufacture the base body from a readily machinable steel, but to choose a hardened steel that is as wear-resistant as possible for the receiving sleeve.
  • the receiving sleeve can, for. B. by kneading or extrusion or sintering or in Investment casting processes made of wear-resistant steel can be produced economically.
  • the receiving sleeve is provided with at least one recess, which, for. B. can be produced in one milling operation.
  • a further expedient development of the receiving sleeve consists in that it has a collar at its end facing the inlet opening for the tool, which collar forms an axial stop on the base body. This gives the receiving sleeve a particularly secure fit in the axial direction.
  • a particularly good non-positive connection between the receiving sleeve and the base body is achieved in that the receiving sleeve is connected to the base body by brazing.
  • the receiving sleeve is connected to the base body by brazing.
  • the base body is provided with at least one locking body, which in one at the shaft end of the The existing groove of the tool can be inserted and is held in its locking position by a locking element, which can be guided into a position that releases the locking body radially via the actuating element.
  • the inventive use of a wear-resistant receiving sleeve ensures a high concentricity of the tool in the tool holder.
  • the locking sleeve 16 is loaded via the holding sleeve 18 with a compression spring 20 in the direction of its locking position.
  • the compression spring 20 is supported on the machine side on the base body 12.
  • the locking sleeve 16 is also supported on the base body 12.
  • the locking sleeve 16 In the locking position of the locking ball 14, the locking sleeve 16 radially covers the locking ball 14, and the holding sleeve 18 secures the locking ball 14 in the axial direction.
  • the tool e.g.
  • FIG. 2 shows a variant of the exemplary embodiment in FIG. 1.
  • Components that are essentially the same are basically numbered with the same reference numerals in the exemplary embodiments described.
  • the description of the exemplary embodiment can refer to the same features and functions be referred to in Figure 1.
  • the embodiment of the tool holder shown in FIG. 2 differs from the embodiment shown in FIG. 1 in that the receptacle sleeve 34 is provided at its end facing the entry opening for the tool with a collar 42 which has an axial stop on an intended one forms end face 44 on the base body 12. This gives the receiving sleeve 34 a particularly secure axial fit in the base body 12.
  • the stop surface 44 can with a z.
  • radially circumferential recess 46 can be provided, in which a brazing material can be introduced to fix the collar 42 on the stop surface 44.

Abstract

L'invention concerne un porte-outil présentant un corps de base (12) doté de moyens de réception d'un outil à manche rainuré. Ce corps de base (12) comprend un mécanisme de verrouillage (14, 16, 18, 20), par lequel l'outil peut être bloqué dans le corps de base (12), et un élément d'actionnement (24) pour le déverrouillage de cet outil. Un porte-outil sans usure, à un faible coût de fabrication, présente un mandrin porte-outil (34) agencé dans le corps de base, lequel mandrin est fabriqué dans un matériau plus dur que le corps de base (12).
