Definitions

  • the invention relates to a chuck for receiving tools that can be used by turning about their axis, in particular screwdriver inserts, with an insertion section having a receiving cavity with a non-circular cross-sectional area, into which receiving cavity the tool can be secured against being pulled out of the receiving cavity by means of a holding element assigned to the cavity wall.
  • which holding element can be deactivated by moving an actuating element, in particular in the form of an actuating sleeve, the tool being supported on the rear in the receiving cavity.
  • Such chucks are described in DE 29 34 428 and DE 199 32 369.
  • the polygonal section of a bit is located in a polygonal bore in an insertion section.
  • a holding element formed by a ball acts on the outer surface of the bit, in particular on its edge or edge recess.
  • the ball is pressed radially inwards against a polygonal flank or into the corner recess by an oblique flank of an actuating sleeve.
  • the required force is supplied by a compression spring that cushions the actuating sleeve, against the spring force of which the sleeve is displaced in the release direction.
  • a magnet forming the bottom of the receiving cavity is provided to increase the holding force. Short and thin bits in particular are difficult to remove from the chuck against the force of the magnet.
  • the invention is therefore based on the object of further developing a generic feed in a manner which is advantageous in terms of use, and in particular of facilitating the removal of the bit.
  • the object is achieved by the invention specified in the claims.
  • Claim 1 aims primarily and essentially that the tool can be displaced from the support position in the direction of the opening of the receiving cavity by actuating the actuating sleeve. According to an advantageous development of the invention, this is done by a tool removal auxiliary member that can be displaced from the actuating sleeve.
  • This tool removal auxiliary member can be a slide assigned to the bottom of the receiving cavity. This slide can be dragged along by the actuating sleeve. This entrainment is preferably carried out in the same direction as the displacement of the actuating sleeve.
  • the slide preferably engages on the rear end face of the tool in order to shift it out of the receiving cavity in some areas, so that the length of the section of the tool which protrudes from the receiving cavity can be attacked. If, in addition, the tool lies against a magnet forming the bottom of the receiving cavity, the end face of the tool is spaced from the magnet due to the slide displacement. A gap is created. As a result of this gap, the holding force exerted by the magnet on the tool is reduced.
  • the holding element is preferably a pressure piece acting in the radial direction on the clamping shank of the tool. This can be designed as a ball. In particular, the pressure piece is designed and mounted as described in DE 101 41 668.7.
  • the actuating sleeve can be displaced against the force of a spring.
  • the slide can be formed by a section of such a spring.
  • only one section of the actuating sleeve spring acts on the slide.
  • a rear end portion of the actuating sleeve spring can pass through an elongated hole.
  • the slider is supported by an angled end section on the plug-in cut formed helical compression spring. This helical compression spring can be supported on the one hand on a support ring which is axially fixed in a circumferential groove of the insertion section.
  • the other end of the helical compression spring is supported on a stop shoulder, which is formed by a retracted collar of the actuating sleeve.
  • This end of the helical compression spring has a radially inward section. This section extends through the elongated hole of the insertion section into the receiving cavity.
  • An angled section of the end of the helical compression spring can then be moved along the cavity wall when the actuating sleeve is displaced.
  • the slide or the spring end has a certain freedom of movement with respect to the end face or with respect to a bevelled end edge of the bit, so that the clamping surface of the actuating sleeve is first displaced in order to allow the pressure piece to escape. Only when this attachment of the tool has been released does the slide or the end of the spring come into contact with the bit in order to displace it inside the receiving cavity in the outward direction.
  • Another aspect of the same invention provides that the end face of the bit rests on a magnet.
  • means are provided with which the end face of the bit can be separated from the magnet. These means make it possible to disengage the end face of the bit from the magnet. This can be done by means of the measures described above.
  • the magnet is spaced apart from the bit, that is to say the bit retains its insertion position within the insertion cavity. As a result of the spacing of the magnet from the end face of the bit, the holding force which the magnet exerts on the bit is considerably reduced, so that even small and in particular short bits can be removed from the chuck without any problems.
  • the bit is preferably supported on a radial projection with an annular region of its end face, which is designed in particular as a chamfer.
  • This radial projection can be a Surround cavity in which the magnet is located.
  • the magnet can be firmly connected to a section of the clamping section.
  • This clamping section has a polygonal cross-sectional shape.
  • This clamping section can be arranged in a rotationally fixed but axially displaceable manner within the insertion section of the chuck. It is axially displaceable there.
  • the clamping section can be axially displaceable between two stops, one stop corresponding to the axial position of the clamping section, in which the magnet lies in flat contact with the end face of the bit. The other stop can be assigned to the spacing position of the magnet from the end face of the bit.
  • this chuck can be brought into a ready-to-take position by moving the actuating sleeve. In the preferred embodiment of the chuck, however, this is not necessary, since the ball can move backwards if it encounters the rear bevel of the bit. If the bit is inserted into the receiving cavity, it lies flat against the bottom of the cavity which is formed by the axially displaceable magnet. It is held by the magnet. The bit is also held by the ball. If the bit is to be removed from the chuck, the actuating sleeve is thus moved away from the clamping section towards the opening of the receiving cavity.
  • the actuating member as a result of a displacement of a clamping section relative to the sleeve section in which the clamping section is inserted, can be locked in its position which holds the holding element out of action.
  • the holding element is brought out of its operative position, so that the bit can be pulled out in its release position without the need to hold the actuating member in place.
  • This function is particularly advantageous if the end of the clamping section lying in the sleeve section carries a magnet which, in the clamping position, bears against the end face of the bit. By moving the clamping section out of the sleeve in regions, the magnet is separated from the bit.
  • the end of the bit is supported on a snap ring which lies in a circumferential groove of the sleeve section.
  • the axial displaceability of the clamping section is limited by stops.
  • a spring ring is used, which lies in a circumferential groove of the sleeve section. It forms a radial projection which lies in a circumferential groove of the clamping section.
  • the axial width of the circumferential groove of the clamping section determines its displacement.
  • the actuating member is preferably fixed by at least one locking body lying in a wall recess of the sleeve section and entering a locking recess in the actuating member.
  • the locking body can be a ball and the locking recess can be formed by an annular groove.
  • the diameter of the locking body is larger than the wall thickness of the sleeve section.
  • the blocking body either protrudes beyond the outer wall of the sleeve section or protrudes into the sleeve cavity. If the locking body protrudes over the outer wall of the sleeve, it can enter the locking recess of the actuating member in order to hold it in the release position.
  • the locking body rests on a lateral surface section of the clamping section and is supported by it. When pushing in Clamping section 15, the locking body can be immersed in an escape niche of the clamping section. In this position, the clamping section is axially movement-bound by the actuating member held in the locked position by a spring.
  • the blocking body In this position, which corresponds to the clamping position of the actuating element, the blocking body is prevented from shifting in the radial outward direction by the cylindrical inner cavity wall of the actuating element.
  • the sleeve forming the actuating member is preferably displaced in the direction of removal of the bit from the locking position into the release position. This takes place against the force of a spring supported against the sleeve section. If the actuating sleeve is displaced into the release position, the ball forming the locking body can enter the ring recess of the actuating sleeve which forms the locking recess. The ball comes out of the escape niche of the clamping section, so that the clamping section can be moved.

  • the rear end of the spring has an extension projecting into an elongated hole 12 of the insertion section 3.
  • This extension 12 protrudes into the receiving hollow 2 in the area of a corner of the receiving hollow 2, and forms with a bend a slide 8 which, in the clamping position shown in FIG. 1, only projects slightly above the bottom 7 of the receiving hollow 2.
