Definitions

  • the invention relates to a chuck for tool inserts according to the preamble of claim 1.
  • a base body serving as a handle has a square receptacle for the square shaft of the tool.
  • a coupling sleeve is rotatably mounted and held axially.
  • the cap sleeve is formed on the end face with a locking plate which has a square opening, the cross section of which corresponds to the cross section of the shaft and the side length of which corresponds to the circular diameter of locking grooves which are arranged in the square shaft.
  • the angle of twist of the coupling sleeve is limited by a screw which penetrates an arc slot of the locking plate and is inserted into the base body between a position in which the opening of the locking plate is aligned with the cross-sectional profile of the receptacle and a position in which the opening of the locking plate against the cross-sectional profile of the receptacle is twisted.
  • the union sleeve is locked by a radially spring-loaded locking ball. If the union sleeve is turned to the position in which its opening comes to coincide with the receptacle, the shaft of the tool insert can be freely inserted or pulled out.
  • the locking tab engages in a locking groove in the shaft and locks it.
  • the twisting of the union sleeve between the two positions must be effected against the resistance of the locking ball. The shaft therefore does not lock itself automatically in the base body of the handle.
  • DE-A-38 29 331 describes a chuck for tool inserts, in which the tool insert used is held in a force-fitting manner by means of a self-locking ball, in that the ball is inserted between one of the six surfaces of the shank of the tool insert inserted into the chuck and the narrowing Wall surface of an axially displaceable sleeve is clamped.
  • the ball To remove the tool insert (bits), the ball must be relieved by moving the sleeve.
  • a disadvantage of chucks of this type is the use of a ball which can be displaced and clamped in the chuck, which makes complex construction necessary for the ball guide and the function of which can be impaired by impurities (such as foreign bodies) entering the chuck.
  • the invention has for its object to provide a chuck of the type mentioned above, which has a high operational reliability, is easy to use and is structurally simple.
  • the locking of the tool insert is effected with a locking plate which is inserted in a union sleeve, whereby the coupling sleeve is arranged rotatably about the axial axis of the chuck.
  • a breakthrough of the locking plate with the cross-sectional profile of the chuck receptacle coincides, so that the tool insert can be freely inserted into the receptacle or pulled out of it. If the sleeve is rotated into a locking position, the locking plate engages in the locking groove of the shaft, for. B.
  • the axial dimension of the chuck according to the invention is shorter than in the known chucks with axially displaceable elements, which makes it advantageously possible to shape the free end of the screwdriver bits longer.
  • the chuck has a clamping pin 2 on which a sleeve-shaped base body 4 is fastened (see FIG. 2).
  • a stop 6 is used in the base body 4, which serves to limit the insertion depth of the tool inserts.
  • This stop 6 can advantageously also consist of a magnet which is used to use the tool inserts, e.g. B. screwdriver bits to exert a magnetic force on the screw.
  • the base body 4 has a hexagon socket 8, the cross-sectional profile of which corresponds to the cross-section of the hexagonal shaft 10 or 30 of a screwdriver bit 11 or 28.
  • a sleeve 12 is rotatably seated on the base body 4, which extends beyond the base body 4 at both ends.
  • the coupling sleeve 12 engages over the clamping pin-side end of the base body 4 inwards up to the outer circumference of the clamping shaft 2.
  • a locking plate 14 rests on the insertion-side end face of the base body 4 and sits firmly in the coupling sleeve 12.
  • the locking plate 14 has a circular central opening 15, the inner circle diameter of which corresponds to the diameter of the locking groove 26 of the hexagonal shaft 10 of standardized tool inserts (DIN 3126 Form C).
  • the opening 15 is widened beyond its circular inner circumference by six essentially triangularly shaped, equidistantly arranged recesses 17 which correspond in profile to the hexagonal corners of the shank 10 and 30 of the tool insert.
  • a coil spring 16 sits on the clamping shaft 2 between the ends of the base body 4 and the coupling sleeve 12.
  • the two spring ends 18a and 18b of the coil spring 16 are each under the torsional force of the coil spring 16 on spring contact surfaces 20a and 20b, respectively, on the base body 4 or the sleeve 12 are recessed.
  • the angle of rotation between the base body 4 and the union sleeve 12 is limited by a radial pin 22 inserted into the base body 4, which engages in a slot 24 running in the union sleeve 12 in the circumferential direction (see FIG. 1).
  • the torsional tension of the helical spring 16 holds the pin 22 at a stop end of the slot 24.
  • the triangular recesses 17 of the locking plate 14 do not coincide with the profile corners of the hexagon socket 8 of the base body 4.
  • the base body 4 and the sleeve 12 can against the spring tension over the length of the slot 24 against each other manually into the other stop position from Pin 22 and slot 24 are rotated.
  • the recesses 17 of the locking plate 14 come to coincide with the profile corners of the hexagon receptacle 8.
  • tool inserts 11, z. B. screwdriver bits that have a locking groove 26 according to DIN 3126-C (Fig. 2).
  • Tool inserts 28 can also be used, the shank 30 of which is rounded from the active side to the area of such a locking groove 26 (FIG. 3).
  • the union sleeve 12 is rotated on the base body 4 against the spring action of the helical spring 16 in the release position (FIG. 4a), in which the breakthrough profile 36 of the locking plate 14 with the cross-sectional profile of the hexagon receptacle 8 Cover comes and the shaft 10 or 30 can be inserted through the locking plate 14 into the base body 4.
  • the screwdriver bit 11 inserted into the hexagon receptacle 8 is then held in a form-fitting manner by the locking plate 14 which snaps back into the locking position (FIG. 4b) by means of the spring force and engages in the locking groove 26.
  • the locking plate 14 bears against the rounded effective end 34 of the shaft 30.
  • the coupling sleeve 12 is rotated counter to the spring force until, in the release position (FIG. 4a), the breakthrough profile 36 of the locking plate 14 is aligned with the profile of the hexagon receptacle 8 of the base body 4. The tool insert 11 or 28 is then easily removable.
  • a slight inclination of the slot 24 against the plane perpendicular to the axis causes on the one hand that the locking plate 14 lifts off the end face of the base body 4 during rotation into the release position and the rotation is not impeded by friction.
  • the tool insert 11 or 28 is also relieved in this way.
  • the tool insert 11 or 28 is pressed slightly axially by the locking plate 14 axially into the hexagon receptacle 8 (in particular in the embodiment of FIG. 3) and axially fixed to the stop 6.
  • the outer surface of the sleeve 12 is shaped as a corrugated handle 38 so that the sleeve 12 can be easily rotated against the base body 4.
