Definitions

  • the invention relates to a chuck for receiving polygonal profiles with a polygonal cross-section having insertion for a polygonal profile, wherein the polygonal profile forms two diagonally opposite outer corners defining a corner measure and the polygonal cross section of the insertion a corresponding thereto, spaced from the Eckraw spaced inside corners corner pair formed.
  • the DE 101 56 459 A1 describes various embodiments of screwing tools.
  • the screwing tools have a chuck for inserting a hexagonal profile.
  • This polygonal profile is either a drive profile of a screwing tool, a bit or a nut or is a plug-in portion of another chuck for receiving in turn a polygonal profile but with a different Eckbrook.
  • the chuck may have a male portion with which it can be connected to a drive motor of an electric screwdriver.
  • the document also describes an embodiment in which the food is directly connected to a handle, so that the handle can be equipped with various output tools.
  • a chuck for receiving tools usable by turning about its axis, in particular screwdriver bits.
  • the hexagonal sections of the screwdriver bits are placed in a receiving cavity of the chuck.
  • the receiving cavity has a hexagonal inner cross section, which corresponds to the hexagonal outer cross section of the hexagonal profile.
  • the hexagonal profile is thus held positively in the recess of the lining.
  • a similarly designed chuck describes the DE 10141668 A1 , Again, there is a hexagonal section in a hexagonal opening of the feed and is held there by means of a pressure ball.
  • Lining is also known which, instead of a hexagonal opening, has a four-edge insertion opening, so that a square profile can be inserted into this insertion opening.
  • the invention has for its object to increase the range of applications of a generic feed.
  • each claim represents an independent solution to the problem and can be combined with any other claim.
  • the lining forms at least one additional pair of corners whose distance dimension is different from the distance dimension of the first corner pair.
  • the cross-sectional shape of the insertion opening is chosen so that either polygonal profiles with correspondingly different corner measures can be inserted into the lining.
  • the geometric arrangement of the corner pairs can be made so that the at least two polygonal profiles are equilateral polygonal profiles. These polygonal profiles can have a different number of edges.
  • the insertion opening can have a substantially square cross-section, wherein a side surface forms a corner recess with a central groove the insertion opening.
  • a polygonal sleeve is provided. This plug in a first insertion and has a second, smaller insertion for a smaller polygonal profile. If a polygonal profile is used with a small corner measure, it can be inserted into the second insertion opening, which is assigned to the polygonal sleeve.
  • the polygonal sleeve can be moved axially within the first insertion. This allows the insertion of a Mehrkantes with a larger Eckfact.
  • the displacement of the polygonal sleeve in the first insertion opening is preferably carried out against the restoring force of a spring.
  • This spring may be located in a housing which forms the first insertion opening. It may be a helical gear spring.
  • a detent can be provided with which the polygonal sleeve is held in its basic position. In the basic position, a front end edge of the polygonal sleeve is aligned with a front end edge of the housing forming the first insertion opening.
  • the catch may be a ball which engages in a latching recess of the outer wall of the polygonal sleeve.
  • the ball can eino in a window of the housing, have a diameter which is greater than the wall thickness of the housing in the region of the window and acted upon by a clamping surface of an actuating sleeve.
  • the actuating sleeve is preferably acted upon by a spring, so that the clamping surface in the normal state acts on the ball forming a pressure piece. Only by axial displacement of the actuating sleeve, the ball can escape radially outward to emerge from the recess. Then the polygonal sleeve can be moved.
  • the polygonal sleeve associated insertion can be configured in the above-cited type to accommodate both a hexagon and a square.
  • the housing formed by the polygonal sleeve overlapping insertion can have a square edge cross-section, for example.
  • insertion openings with a different cross-sectional profile are arranged axially one behind the other, wherein the polygonal section immediately adjacent to the mouth of the insertion opening has the larger corner which may also be in the form of the variant discussed at the outset, that is, capable of accommodating both a 1/4 "hexagon and a 1/4" square, the second polygonal zone located behind it in the axial direction, that is to say remote from the mouth of the insertion opening
  • a square section inserted in this lining can only be inserted up to the boundary between the first and the second polygonal section, whereas a hexagonal section can be inserted into the second polygonal section
  • More Edge sections preferably an identicalommenabstandswin but a mutually different Eckeniere.
  • FIG. 1 to 8 is a screwing tool with a handle 19.
  • the end face of the handle is associated with a chuck 1. It is possible to insert in the chuck 1 a 1/4 "hexagonal profile 8, a 1/4" square 9 or a 3/8 "square 10 optional.
  • the chuck 1 has in its end face 1 'initially a square opening 2.
  • This forms an insertion opening for inserting a 3/8 "square profile .
  • the insertion opening 2 has a total four slightly rounded corners 6. In these corners 6 are in the normal state outer corners of a polygonal sleeve 7, which rests in the insertion opening 2. Two diagonally opposite corners 6 are spaced apart by the Eckproof E3.
  • the polygonal sleeve 7 has a square outer contour and a rear end face 7 'which rests in the insertion opening 2 and is acted upon by a compression spring 18.
  • the compression spring 18 is supported at its other end at the bottom of the insertion opening 2 or at the bottom of one of the bottom of the insertion hole associated recess.
  • a rear portion of the side wall 2 'of the insertion opening 2 has sickle-shaped, axially extending grooves 21 which terminate in front of a lying in the region of the mouth of the insertion opening 2 stage. In these grooves 21 engage shoulders 20, which adjoin the bottom 7 'of the polygonal sleeve 7, a.
  • a detent ball 16 engages in the detent recess 17.
  • the detent ball 16 lies in a window 14 of a housing 15, which forms the insertion opening 2.
  • the diameter of the ball 16 is greater than the wall of the housing in the region of the window 14, so that the ball 16 on the radially outer side of the window 14 from a clamping surface
  • An actuating sleeve 11 can be acted upon by the clamping surface 12.
  • the actuating sleeve 11 is acted upon by a helical compression spring 13 in a detent position in which the ball 16 can enter the detent recess 17.
  • the latter is done by inserting a 3/8 "square profile 10 into the outer insertion opening 2.
  • the rear end face of the 3/8" square profile 10 acts on the front end face 7 "of the polygonal sleeve 7.
  • the 3/8 "square 10 has a recess 23 (locking recess) which in this position the position of the locking recess 17 in Figures 3 and 5 occupies.
  • the ball 16 engages in the latching recess 23 and is held by the clamping surface 12 therein.
  • the square 10 is tied in the axial direction. Along with this, the position of the polygonal sleeve 7 is also fixed.
  • the inner insertion opening 3 of the polygonal sleeve 7 likewise has a square outline.
  • the opposing inner walls 3 ', 3' are spaced apart by the area distance of a 1/4 "square profile, so that a 1/4" square profile 9, for example, a nut can be inserted into the insertion opening 3.
  • the side surfaces 9 'of the 1/4 "square profile 9 lie in surface contact with the surfaces 3' of the insertion opening 3.
  • the corners 9" of the 1/4 "square profile 9 lie in the region of the rounded corners 5 of the insertion 3. Der Distance between two diagonally opposite corners 5 of the square insertion opening 3 defines another corner E 2.
  • a third corner dimension E1 defines the distance between the groove bottoms of two grooves, which in the insertion direction are in the middle of two opposite inner walls 3 '. the insertion opening 3 run. These grooves form two diagonally opposite corners 4, which are spaced from each other by the E1 corner measure.
  • the two diagonally opposite corners 8 "of a 1/4" hexagonal profile 8 engage in these grooves.
  • Two diagonally opposite polygonal surfaces 8 'of the 1/4 "hexagonal profile 8 lie in surface contact with the groove-free inner walls 3', 3 'of the insertion opening 3.
  • the 1/4 "square profile 9 may have a detent ball 22 which acts to secure the position of the square profile 9 in the insertion opening 3 a side wall 3 '.
  • FIG. 9 to 15 is the development of a quick-change chuck, as for example. From the DE 102 54 339 A1 is already known. In this feed, a clamping shaft 25, with which the feed is connectable with an electric screwdriver, inserted in a plug-in socket 29 a.
  • the plug-in socket 29 has a total of a continuous 1/4 "hexagonal profile.
  • the insertion opening has two sections 30, 31 which are arranged one behind the other in the axial direction.
  • the section 31 which is remote from the opening of the insertion opening and adjoins the bottom of the insertion opening, which is formed by the end face of the clamping shaft 25, has a 1/4 " It is thus ensured that in this profile section 31, a 1/4 "-Sechskantprofil 8 can be inserted.
  • the 1/4 "hexagonal profile 8 is formed by a clamping section of a screwdriver bit.
  • the adjoining the mouth of the insertion profile section 30 has a similar profile, as has already been discussed with reference to Figure 2. It has a square cross-section with a total of four corners 5. Two diagonally opposite side walls of the Square profiles 30 have grooves extending in the insertion direction, the grounds of which form a further pair of corners 4. The corner measure, with which the corners of the corner pairs 4 are spaced from each other, corresponds to the corner of the corners of the hexagonal portion 31.
