Definitions

  • the invention relates to a nipple clamp for impeller assembly, with a body that has a forked open end for mounting on a spoke and a drive train mounted in it having multiple gears, which is the forked open end of the base body facing last gear is slit longitudinally to encroach on the spoke and has a receiving space in which a longitudinally slotted Clamping ball with one intended for rotary grip on a nipple Square cross section is housed.
  • Such nipple clamps sometimes also called nipple hands, are used in tensioning stations or tensioning machines used for impeller assembly. They serve the nipples of an impeller one after the other unscrew the threaded ends of the spokes and thus to tension the impeller.
  • a nipple clamp of the type described above is known. He has a housing-like body that is elongated Has shape. There is a drive train in the main body made up of several gears that mesh, the drive via a motor or the like from one side the drive train is initiated in this and over the Gears continues to the other last gear. in the Area of this last gear wheel facing the impeller the base body has a fork-shaped opening or a frontal end with which he spoke the spoke in question Impeller can overlap. For the same purpose, the last one is Provide the gear with a longitudinal slot. It continues to point in inside a recording space, so it is largely hollow designed, in the receiving space a tension ball, d. H. the actual clamping tool is arranged.
  • the tension ball has a continuous longitudinal slot, so that it over the Spoke can grip. It is important that the tension ball over it also has a square cross section, that is, a recess with a square cross-section, with which they on the nipple can attack.
  • a nipple To tighten a nipple, it is first necessary the longitudinal slots in alignment with each other on the free fork-shaped end assigned to the spoke to be spanned, align. The nipple clamp is then with its main body passed over the spoke so that the axis of the spoke through the last gear and the clamping ball passes through.
  • the Square cross-section brought into engagement on the nipple. At the Turning the rotary drive in this way becomes the nipple - depending on the direction of rotation - turned on the spoke or in Turned off to loosen up.
  • the invention has for its object a nipple clamp to provide the type described above, the improved Axis alignment of the clamping ball relative to the axis of the Spokes and where there is a risk of scratching the Spoke surface during the turning attack of the tension ball the nipple is removed.
  • this is the case with a nipple tensioner described type achieved in that a longitudinally slotted Protective sleeve is provided, which is non-rotatable on the base body is stored.
  • the invention is based on the idea of a clamping ball Assign protective sleeve, which as a separate part in addition to the clamping ball is provided and matched to this.
  • the nipple can twist relative to the spoke Protective sleeve rotatably mounted on the base body.
  • the protective sleeve also has a longitudinal slot that runs the length the protective sleeve goes through and for the purpose of putting on the Nipple clamps on a spoke with the longitudinal slot of the clamping ball and the longitudinal slot of the last gear in alignment can be brought.
  • the longitudinal slot is always on the same place, so aligned to the open fork-shaped End of the body.
  • the protective sleeve therefore does not require any additional drive and also no control to escape of the longitudinal slots.
  • the longitudinally slotted protective sleeve the end facing the nipple protecting the spoke. Since the protective sleeve for the spoke is none Relative movement is also an impairment of the Surface of the spoke excluded by scratching. If the Then clamping ball with its axis relative to the axis of the Protective sleeve is aligned, there is no risk that the clamping ball the surface of the Spoke reached.
  • the protective sleeve is not only the Function provides to protectively surround the spoke, but also causes an additional guide for the clamping ball. So it is possible that the protective sleeve an extension and the Have a recess corresponding to the extension, to form a guide bearing for the rotatable clamping ball interlock.
  • the protective sleeve thus provides one double management function. It extends the tension ball as it were, so that the unit consists of a tension ball and a protective sleeve due to their increased axial extension better and can align more precisely to the axis of the spoke if at the beginning of a clamping process of the nipple clamps in overlap with the Spoke is brought.
  • the second management function of the protective sleeve is that it is a plain bearing for the clamping ball forms, so that in the subsequent rotary drive of the clamping ball this with its inner surface nowhere the surface of the Spoke can reach. This makes it possible to color yourself painted spokes on wheels without any impairment to stretch.
  • the protective sleeve and the clamping ball on the base body is pivoted about a common axis are. This also ensures that when swiveling or tilt the axis of the protective sleeve about this common axis and do not move the axis of the clamping ball against each other, so that will never leave their alignment.
  • the clamping ball can be placed in the assigned to the fork-shaped end of the base body gear be pivoted.
  • a swivel lever can be provided be pivotable about the pivot axis of the clamping ball the body is stored.
  • the protective sleeve is on the swivel lever non-rotatably mounted.
  • For the non-rotatable storage of the Protective sleeve on the swivel lever there are various ways for example an at least partially out-of-round design the protective sleeve and the swivel lever. But also screw and Setting connections are possible to this function fulfill.
  • the longitudinal slot of the protective sleeve and the longitudinal slot of the clamping ball have a smaller width than the square cross-section the tension ball on. This allows the nipple clamp on the one hand, put it well over the spoke and on the other hand in move a small stroke in the axial direction so that the square cross-section the clamping ball on the square cross section of the Attacks nipples. Even with this axial movement with a small stroke there is no risk of damaging the surface of the spoke.
  • the longitudinal slots especially in Bottom of the recess, rounded and adjusted so that after the Put the nipple tensioner on the spoke this slight Stroke possible without affecting the surface of the spoke becomes.
  • the clamping ball two diametrically has oppositely arranged recesses into which the gear assigned to the fork-shaped end of the base body Insert the provided support screws.
  • the support screws can be designed as grub screws. They form a swivel axis which are at right angles to the axis of the clamping ball and the Gear is arranged. About this pivot axis aligned alignment of the clamping ball and the protective sleeve relative possible to the axis of the spoke. It is understood that the constructive arrangement of a certain swivel range sufficient is to the helix angle ranges of the left and right Row of spokes to operate an impeller.
  • the protective sleeve can be at its end facing away from the extension Have thickening by the longitudinal slot of the protective sleeve is also enforced. This thickening is useful to the Protective sleeve also in the axial direction relative to the pivot lever to store and so over the tension ball during its rotation to effectively support the plain bearing.
  • the thickening of the Protective sleeve can be on its opposite the longitudinal slot Have a flat on the outside. This flattening serves the anti-rotation bearing of the protective sleeve on the swivel lever.
  • the nipple clamp has a housing-like base body 1, which with a Lid 2 and a plate 3 can be closed from above.
  • the Base body 1 has a fork-shaped on one transverse side open end 4, which forms a longitudinal slot. This fork-shaped design and the longitudinal slot also sit in the plate 3 continues.

  • the gear 8 (Fig. 2 and 3) is hollow and has in Interior of a receiving space 9, which is used to accommodate a Clamping ball 10 (Fig. 4 to 6) is used.
  • the clamping ball 10 has one along the length of the longitudinal slot 11.
  • the Gear 8 otherwise has a longitudinal axis 12 and teeth 13. Der Longitudinal slot 11 connects radially to the receiving space 9.
  • the pivot axis 16 represents the axis to which the clamping ball 10 in the receiving space 9 relative to the Gear 8 can be pivoted.
  • the arrangement of the teeth 13 relative to the longitudinal slot 11 is such that the tooth base and the longitudinal slot 11 coincide (Fig. 3). To this It is possible to also drive gear 5 with gear train 8 to drive reliably rotating, despite the arrangement of the continuous longitudinal slot 11.
  • the gears 6 and 7 have no longitudinal slot.
  • the tension ball 10 has a spherical shape, an axis 17 and one of the Length after continuous longitudinal slot 18 which is chamfered (Fig. 6), at this point to put on a spoke facilitate.

In the starting position when the drive train 5 is stopped, the overlap Longitudinal slots 11, 18, 27, 34 so that the nipple clamp with its free end 4 can be placed on a spoke. A piston / cylinder drive, not shown, also serves for this purpose a linear movement. During this touchdown occurs the spoke in question through the aligned longitudinal slots 11, 18, 27, 34 through. Due to the swiveling mounting of the clamping ball 10 and the protective sleeve 23 around the also coincident Swivel axes 16 and 29 automatically align the common axes 17 and 25 to the axis of the spoke. there the protective sleeve 23 surrounds the spoke on three sides, as it were.
  • the protective sleeve 23 Since the protective sleeve 23 is secured against rotation, it can do not make any relative movement to the spoke and therefore also do not scratch the surface of the spoke. Subsequently there is a slight movement of the nipple clamp in the direction the axis of the spoke towards the nipple. Because the axis alignment has already taken place previously, the clamping ball 10 with the truncated cone 21 on the nipple and the Square cross-section 20 the square cross-section of the nipple reach around or take up. Then when the drive train 5 in motion is or will be set, the nipple is depending on which is switched on Direction of rotation tensioned or slightly loosened.
  • the protective sleeve 23 prevents the tension ball 10 on the surface of the Spoke strikes.
  • the protective sleeve guides with the help the guide bearing 19, 24 the clamping ball 10 during their Rotation around its axis 17.
  • the drive train 5 is stopped so that in turn Cover longitudinal slots or align with each other so that the Nipple clamps can be removed from the spoke in question can.
  • the nipple clamp achieves automatic angular alignment to the axis of the spoke, so that it slopes the left and right row of spokes can take into account.
  • the Nipple clamps can work alternately or in rows be used working.
