Definitions

  • the present invention provides an automatic device for unscrewing and depositing a pinning screw clip, which does not have any of the aforementioned drawbacks.
  • a first advantage of the device according to the invention lies in its simplicity of implementation as a hand pneumatic unscrewer nose used in most cases in the aeronautical field.
  • a second advantage consists in that this nose is also adaptable to the arms of the robots which can be, moreover, the same as those which pierce the staple holes and which lay the rivets for final fixing.
  • a third advantage consists in that this nose is of reduced size, thus allowing access to the staples placed in the areas of high density.
  • the body of the staple could also be held and immobilized by a hexagonal conformation of the body, which meant that the nose of the screwdriver could then comprise two rotating tubes coaxially and each terminated by a hexagonal imprint; the inner tube for the nut and the outer tube for the body of said clip.
  • pneumatic screwdrivers were going to benefit from a significant improvement consisting in putting the engine in stalling by screwing or unscrewing as soon as the appearance of a predetermined torque, which had the advantage of considerably reducing air consumption without damaging the equipment.
  • a screw pinning clip essentially comprises on the one hand, a hollow body 1 which may be made of plastic and which is integral with a spacer 1 'situated between the clamps 2 'and 2 "secured to a screw 2, and on the other hand to a spring 3 and a nut 4 engaged on the screw 2 and which acts against said spring 3.
  • the usual pneumatic system moreover comprises a body 5 receiving the motor (not shown) which drives in rotation an inner tube 6 provided with a hexagon at its end while two other tubes, one of which is external marked 7 and finished in its end by a hexagon is fixed by its connection to 5 and, the other, marked 8 and which is intermediate is also terminated at its end by an imprint also hexagonal.
  • the staple is in place and is locked when the tube 8 has turned 1/12 of a turn so that the the hexagon footprint plates of 8 are located under the points of the hexagon in the hexagonal part of the clip.
  • the clip thus grasped and locked is introduced into the hole of the assembly consisting of the sheets 9 and 10 and of the interposition product 11.
  • the nut 4 is screwed to a preset torque so that the pliers 2 ' and 2 ", moving away, come to hang on the face opposite of the assembly thus producing under the effect of the spring 3 the approach of the sheets 9 and 10 towards each other.
  • the nose can then be evacuated after rotation of 1/12 of a turn of the tube 8 relative to the tube 7.
  • the nose is replaced on the clip to lead, after proper unscrewing of the nut 4, to the complete extraction of the latter.
  • FIG. 4 is well representative of the problems encountered prior to the application of the invention insofar as the excess of product 12 was lodged in the hole even as a result of the pressurization of the sheets, thereby making it extremely difficult to extract the clip from its hole.
  • the unscrewing and extraction nose comprises, as will be explained below, a part bearing on the assembly while a jack comes to evacuate the clip from its hole as soon as the unscrewing phase of the nut.
  • Such a nose essentially comprises, as can be seen from FIG. 5, a motor part, a bushing part and a piston part.
  • the motor part is known per se, and can result either from an adaptation in hand pistol conformation, or from a more advanced conformation in an automated station in robotic applications.
  • the air motor begins by driving the bush 13 in rotation via the axis 14 and the reference motor 15.
  • This socket 13 is screwed by a thread 13 'not to the left, in another socket 16 which can rotate angularly by 30 ° to lock or unlock under the effect of friction in the screw threads and by the fact of light made in part 16 as shown in detail in FIG. 6.
  • the socket 16 is moreover immobilized in translation, as shown in Figure 7, by the axis screw 17 which allows only its single rotation of 30 °.
  • Locking takes place under the effect of the rotation of the sleeve 16 in front of the lock 18 which is itself immobilized in rotation relative to the external body 19 by means of the screw 20 which also subjects it in translation relative to the socket 16.
  • the body 19 is also immobilized in rotation on the piston 21 via the axis of the stop ring 22.
  • the piston 21 is immobilized in rotation relative to the inner cylinder guide 23 by the pin screw 17.
  • the sleeve 13 advances axially in the sleeve 16 by the fact of the presence of the left-hand thread 13 'and this, until the screw 24 comes to abut at the end of the axial light 24' made in part 15 which causes the engine to stall.
  • the sleeve 13 causes in its axial displacement, the axis 14 which then pushes on the screw of the staple marked 2.
  • said socket 13 comprising a ring 13 "with internal hexagonal imprint and having a thread in the socket 16 which is not less than the pitch of the nut 4 of the clip, advances faster than recedes said nut 4 and that, as a result, the spring 25 is then compressed under the effect of said ring 13 'which ejects, during unlocking, the clip from the nose of the screwdriver.
  • the engine part comprises two conduits, one 26 communicating the pressure of the PM motor towards the differential marked 28 in FIG. 8, the other marked 27 bringing the pressure of said differential 28 to the jack by the chamber 21 '.
  • the pressure having increased on the motor side PM, and the control pressure PT being fixed, allows the differential 28 to let air pass through the duct 27 to the chamber 21 'of the O-ring cylinder 32 and 33.
  • the piston 21 thus actuated pushes on the external body 19 which consecutively moves the clip away from the surface of the assembly formed by the sheets 9 and 10.
  • the socket 16 which carries an internal hexagon at its end, can rotate 30 ° (or 1/12 of a turn) in front of the other hexagon ring or latch 18 thanks to the presence of the screw axis 20, as shown in detail in FIG. 6.
  • the sleeve 13 moves back until the axis 14 comes up against the driver 15 from which the stalling of the motor results, which means that the stapler is in the rear position and ready to extract the next clip.
  • the differential 28 according to FIG. 8 has a flexible membrane 39 defining two chambers: one 40 PM pressure inlet, by the engine return conduit by conduit 26, and returning to the cylinder by conduit 27, the other 41 receiving the pressure witness PT arriving by conduit 42 and which may possibly be adjusted by the needle screw 42 '.
  • the differential 28 can be fixed as desired, either on the lower part of the stock 36 of an air pistol of the usual type (as is more particularly shown in FIG. 9), or on a robot head known per se 43 (not shown further in this description).
  • the operator apprehends in the usual way the stick 36 provided at its end with the pressure differential 28 while this differential is itself connected to the air intakes by the conduits 26 (PM ) and 27 (PV) passing through the trigger guard 44 further constituting physical protection of the operator's hand.
