Definitions

  • the present invention relates to an apparatus for the semi-automatic screwing of fastening elements made of at least two preassembled parts, one of which is constituted by a support and / or fixing piece, while the other comprises a screw preengaged in a hole of the first part.
  • fixing elements comprising a tubular shaft of internal diameter at least equal to that of the head of the screw used, one end of which is provided with a retaining collar, for example circular or rectangular, which extends substantially radially and whose other end, usually of pointed shape, has a bore narrowing of diameter smaller than that of the head of the screw.
  • screwing devices comprising a magazine in which is stored a plurality of fasteners of this type, a dispenser for bring one by one the fastening elements in a screwing zone and screwing means capable of screwing the screw.
  • this apparatus comprises a magazine constituted by a guiding device comprising two parallel profiled guides having two respective concavities in the form of grooves facing each other so as to delimit a substantially cruciform space comprising two closed branches in which the fasteners can engage and be guided by the side edges of the collars and two open branches in which the screws pre-engaged in the fasteners and / or drums can pass.
  • WO 02/057054 discloses an apparatus for screwing fasteners, comprising a screwdriver / unloader carried by a carriage movable along lateral guide means parallel to the axis of the screwing rod, a screwing well, a magazine constituted by the two lateral guides and a central guide, a distributor of fasteners in which opens the lower end of the magazine, the two lateral guides being extended beyond the dispenser by a curved portion for bringing the fasteners to the right of the screwing tools.
  • Requirement DE 101 02 704 discloses an apparatus for screwing fasteners, comprising a screwing device driven by a screwdriver / screwdriver, the screwing device comprising a screwing rod inside an axially movable tubular element, so that its end bottom end presses on the collar of the fastener at the same time that the end of the screwing rod engages the head of the screw, so as to prevent the fastener from rotating.
  • the object of the invention is therefore more particularly to eliminate these disadvantages.
  • the movements of the drawer are controlled by the movements of the screwdriver / unscrewing through a conversion device vertical translation / horizontal translation.
  • an additional guide element may be associated with the lateral guides downstream of the distributor to hold the fastening elements whose collars have rectangular shapes oriented parallel to the axis of the lateral guides.
  • a stop element may be provided at the distributor so that the polygonal or oblong collars are arranged in this direction in the gap between the fork and the support part of the drawer.
  • the screw well has a height greater than the maximum height that can have a fastener, from the collar to the tip of the screw.
  • the well comprises retractable retention means for retaining the collars of the fasteners until the screwing rod of the screwdriver / stripper engages in the barrel of the fastener which is is retained and comes into engagement with the head of the screw, these retention means then retracting under the effect of the pressure exerted downwards by the screw rod on the fastener.
  • the collars of the fastening elements are guided by two substantially vertical plates of slightly concave profile arranged one opposite the other, one of these two plates being articulated in its part. lower and being biased by elastic means towards the other plate to a position in which these two plates are spaced apart from each other by a predetermined minimum distance.
  • the apparatus according to the invention has a relatively simple structure, inexpensive and nevertheless allows a particularly reliable operation for fasteners that can have different shapes and dimensions.
  • the device according to the invention applies to the installation of a fastening element 1 comprising a tubular shaft 2, one end of which is provided with a retaining collar 3 while the other end, of substantially This frustoconical element has a boring narrowing 4.
  • this element is made of plastic molded so as to avoid any thermal conduction bridge.
  • the element 1 cooperates with a screw 5 which engages in the bore 6 of the drum 2 and passes through the bore narrowing 4.
  • the head 7 of the screw 5 has a diameter substantially equal to the diameter of the bore 6. As a result, it is guided by this bore. At the end of screwing, this head 7 abuts against the bearing making the transition between the bore 6 and the bore narrowing 4.
  • the bore 6 of the barrel 2 is provided with one or more protuberances 8 that the head of the screw must cross, forcibly, causing a slight elastic deformation of the drum 2.
  • This operation can be carried out at the factory during the pre-assembly of the screw, using a special tool. It can also be done in situ, by the operator.
  • the bore narrowing 4 is itself provided with one or more axial protuberances intended to allow to obtain a screwing effect of the screw 5. Thanks to this arrangement, the passage in force of the screw 5 by the protuberances 8 of the barrel 2 can be obtained thanks to this screwing effect.
  • the shapes and dimensions of the fasteners usable by the apparatus according to the invention can be very different and correspond to the ranges of fasteners of this kind currently available on the market.
