  • This invention relates to blind riveting apparatus for setting blind tubular rivets of the kind comprising a shank and an enlarged head at one end of the shank, and having a bore extending through the head and shank.
  • Such rivets are well known and are commercially available under the registered Trade Mark Chobert.
  • the invention relates to blind riveting apparatus which is adapted to supply blind tubular rivets to a setting station, and to set the rivets at the setting station.
  • blind riveting apparatus comprising anelongated mandrel having an enlarged head and a stem extending rearwardly of the head, holding means for holding the mandrel and providing an abutment for supporting a rivet in a rivet setting operation, axially reciprocable gripping means for gripping the mandrel at a position rearwardly of the holding means and for moving the mandrel axially relative to the abutment to pull the enlarged head through a tubular rivet supported by the I rearward position (as shown in FIG. 1), and a forward position (as shown in FIG. 4).
  • I rearward position as shown in FIG. 1
  • FIG. 4 a tubular rivet supported by the I rearward position
  • the means for advancing a rivet along the mandrel may comprise means for directing a jet of gas forwardly onto a rivet positioned on the mandrel axis.
  • FIG. 1 is a schematic elevation, partly in section, showing the principal parts of a riveting machine and a riveted workpiece, the machine having just set a rivet in the workpiece;
  • FIGS. 2, 3 and 4 are schematic elevations, partly in section, similar to FIG; 1 but showing the positions of the principal parts of the machine in further stages of operation and FIGS. 5 and 6 are fragmentary elevation and plan views, respectively, of parts of the machine.
  • the machine of this embodiment is adapted to set blind tubular rivets in a workpiece at a setting station from a position below the workpiece.
  • the head 16 of the mandrel is disposed between the nose-jaws 18, 20'
  • a forward position (as shown in FIG. 4) and, in their rearward position, are movable between a closed position in which they co-operate to grip the mandrel as shown in FIG. 1, and an open position in which they are disengaged from the mandrel as shown in FIG. 2.
  • Each of the gripping jaws 26, 28 is provided with four gripping fingers which are arranged to interdigitate with the four gripping fingers of the outer gripping jaw, two of the gripping fingers 42, 44 being vertically spaced one above the other on one side of the mandrel stem and diverging from the other two gripping fingers 46 (of which only one isshown) which are also vertically spaced one above'the other on the other-side of the mandrel stem, the gripping fingers of the two gripping jaws being arranged to interdig'itate leaving a rectangular space between them in which the stem of the mandrel is gripped.
  • the gripping jaws are poweroperated to move between their open and closed positions by means of pneumatically operated piston cylinder arrangements as shown schematically at 26a and 28a, and are reciprocable in their closed condition in a direction lengthwise of the mandrel by means of a pneumatic
  • the riveting machine comprises a mandrel 12 having an elongated stem 14 and a head 16 at one end of the stem.
  • the stem 14 is cylindrical, and the head 16 is of circular cross-section and tapers towards the stem so as to provide a conical surface 17.
  • the head end of the mandrel is regarded as the forward end, the other end being the rear end of the mandrel.
  • the mandrel is reciprocable along its axis in relation to a pair of nose-.
  • the nose-jaws 18, 20 each present a forwardly facing abutment surface 22, 24 respectively.
  • the nose-jaws are resilientlyv urged towards each other by springs shownschematically at 18a and 20a so as to close about the mandrel. In the closed position. of the nose-jaws, the abutment surfaces 22, 24 co-operate to form a substantially annular abutment peripherally of the mandrel.
  • a rivet feeding means 30 is disposed at a position which is rearwardly of thegripping jaws when the jaws are in their rearward position and is arranged to feed rivets successively into a position in which their bores are aligned with the mandrel axis and their tail ends are directed towards the head of the mandrel.
  • a jet 32 is arranged on the. axis of the mandrel at a position which is to the rear of the rear end of the mandrel when the mandrel is in its rearward position, and is arranged to deliver a blast of gas under pressure, such as compressed air, forwardly along'the stern of the mandrel.
  • FIG. 1 in which the mandrel is in its rearward position, the gripping jaws have just pulled the-mandrel rearwardly and have thereby drawn the head of the mandrel through the bore of a rivet 40 and set the rivet in the aperturedworkpiece 38. It will be seen that the rear end of the mandrel has entered thebore of a rivet 34 which has previously been located in line with the mandrel axis by the feeding means 30.
  • the nose-jaws 18, 20 are resil drel which continues to be held by the nose-jaws, and
  • the machine is now in a condition ready to be actuated to set the rivet 34.
  • An apertured workpiece. may now therefore be positioned so that the head of the mandrel and the'shankof the rivet 34 extend through the workpiece and so that the lower surface of the workpiece abuts the head of the rivet 34.
  • the gripping jaws move rearwardly, pulling the mandrel rearwardly so as to draw the head 16 through the bore of the rivet 34 to set the rivet 34.
  • the rear end of the mandrel stem enters into the bore of the further rivet 36.
  • the machine thus reaches again the condition shown in FIG. 1 and the sequence of operations previously described is carried out to advance the rivet 36 forwardly along the mandrel to the position occupied by the rivet 34 in FIG. 4.
  • the machine is operated entirely by pneumatic power using pneumatic piston/cylinder arrangements to translate the power into linear movement of jaws, but it will be appreciated that, instead of using pneumatic means for effecting the reciprocation of the gripping jaws and the opening and closing movements of the gripping jaws and the nosejaws, other means'such as rotating'or sliding cams or electrically powered actuators could be used.
  • pneumatic means for effecting the reciprocation of the gripping jaws and the opening and closing movements of the gripping jaws and the nosejaws could be used.
  • other means' such as rotating'or sliding cams or electrically powered actuators
  • blind riveting apparatus comprising an elongated mandrel having an enlarged head and a stem extending rearwardly of the head, holding means for holding the mandrel and providing an abutment for supporting a rivet in a rivet setting operation, axially reciprocable means for gripping the mandrel at a position rearwardly of the holding means and for moving the mandrel axially relative to the abutment to pull the enlarged head through a tubular rivet supported by the abutment, the
  • holding means and the gripping means each being operable to release the mandrel when the other of the holding and gripping means is holding the mandrel, to allow a rivet to move forwardly along the mandrel past the gripping means and the holding means, and means for advancing forwardly along the mandrel past the gripping means and the holding means a rivet supplied to the rearward end of the mandrel.
  • blind riveting apparatus comprising means for directing a blast of gas forwardly on to a-rivet positioned on the mandrel axis.
  • blind riveting apparatus according to claim 1, wherein the gripping means comprises a pair of pneumatically operated gripping jaws.
  • blind riveting apparatus according to claim 1, wherein the holding means comprises a pair of power operated jaws which, when closed, co-operate to hold the mandrel and to provide the abutment.
