Definitions

  • the invention relates to an application unit for a sealing compound for the automatic sealing of riveted joints.
  • an automatic riveting machine consisting essentially of a drilling feed unit, a rivet feed unit and a riveting unit, each of which is designed to be controllable, the units being movably supported on a holding bracket in guides pointing in a radial direction toward the riveting point and the holding bracket has pneumatic couplings, electrical plugs and a clamping device for coupling the riveting machine to a production robot.
  • This can be used, for example, to produce riveted connections on an aircraft structure component using an appropriate program.
  • the rivet holes are drilled, and the rivets are inserted and squeezed in an automatic production process.
  • a sealant dispenser which can be used with an automatic riveter, which has means for drilling the rivet holes and for setting the rivet and which comprises a control system whereby the functions of the means are coordinated.
  • Devices are also provided in order to move the dispensing device towards or away from a rivet hole after a certain amount of the sealing compound has been dispensed. These devices are supplied with energy by compressed air, which is used both for moving the dispensing device and for transporting the sealing compound.
  • the sealing compound is located in a container which, on the one hand, is connected to a compressed air source and, on the other hand, to an output head for the sealing compound via corresponding hose lines.
  • the dispensing head includes, inter alia, a check valve, a dispensing valve and a piston / cylinder arrangement which come into contact with the sealing compound during operation.
  • the invention has for its object to provide an application unit for a sealant for arrangement on the bracket of an automatic riveting machine so that it has no moving parts that come into contact with the sealant during operation.
  • the amount of sealant to be dispensed is precisely adjustable. Since only the compressed air supply to the application unit is switched by means of the ventilation valve, the previously required cleaning of moving parts and hoses that come into contact with sealing compound during operation is eliminated.
  • FIG. 1 shows an overview of an application unit 1, which is mounted on a holding bracket 2 of the automatic riveting machine.
  • the entire holding bracket 2 can be moved in the x ', y' and z 'direction by means of a production robot.
  • the application unit 1 is shown in the rest position and essentially comprises a guide 3, a slide 4 which can be displaced in the x direction on the guide 3, a carrier 5 guided in a transverse guide 7 for the application head 6 and a cartridge 8 which is connected to a compressed air line 9 and a dispensing nozzle 10 communicates.
  • the embodiment according to the invention shown has a vent valve 28 which is switched on in the compressed air supply of the application head 6.
  • a pneumatic cylinder is integrated in the guide 3, as a result of which the carriage 4 can be moved from its rest position shown in the image to the left by a predetermined distance into the delivery position and vice versa.
  • the transverse guide 7 is arranged perpendicular to the slide 4 and enables the carrier 5 to be displaced in the y direction by means of a further pneumatic cylinder 11.
  • the carrier 5 is thus opposite the Holding bracket 2 can be moved in the x and y direction.
  • Both cylinders, the one integrated in the guide 3 and the pneumatic cylinder 11, are effective in both directions.
  • two conventional non-contact limit switches are arranged, which detect the relative movement of the carrier 5 with respect to the transverse guide 7 and emit a corresponding signal when the predetermined positions of the carrier 5 are reached.
  • FIGS. 4 and 5 show details of the guides 3 and 7 described above.
  • the carriage 4 forms the first leg of an angular holder 13, the second leg of which, in the image, is directed vertically upwards and carries the transverse guide 7.
  • the transverse guide 7 consists essentially of a guide rail 14 of U-shaped cross section, in which a prism 15, which is firmly connected to the carrier 5, is guided perpendicular to the longitudinal extension of the guide 3.
  • the pneumatic cylinder 11 is firmly connected to the slide 4.
  • the relevant piston rod 12 acts on a boom 16, which in turn is firmly connected to the carrier 5. Two compressed air connections 17 and 18 are used to supply compressed air. In the rest position of the carrier 5 shown, the piston rod 12 is in its upper position.
  • the guide 3 is formed by a so-called rodless pneumatic cylinder, as is known for example under the name Martonair LINTRA.
  • the fixed part of the guide 3 is firmly connected to the holding bracket 2.
  • the pneumatically generated movement of the internal piston is removed at a power bridge 3a, with which the carriage 4 is firmly connected.
  • the internal cylinder is supplied with compressed air via corresponding compressed air connections 19 and 20.
  • a conceivable embodiment of the application unit is that corresponding electric motors are provided for actuating the slide 4 and the carrier 5.
  • a receiving sleeve 23 is arranged axially displaceably within the housing 21, a compression spring 24 being provided, which counteracts a shifting of the receiving sleeve 23 upwards in the figure.
  • the lowest position of the receiving sleeve 23 results from the fact that a nut 25 screwed onto the upper end of the receiving sleeve 23 bears against the housing 21. In this position, the spring 24 is under a prestress.
  • a clamping sleeve 27 provided with an external thread 26 is screwed into the lower end of the housing 21 and contains a previously inserted cartridge 8.
  • the dispensing nozzle 10 is screwed into the cartridge 8 from below and secured by a union nut 29 screwed onto the clamping sleeve 27.
  • the dispensing nozzle 10 has a centering mandrel 30 at its lower end, which merges into a shoulder 31. From the shoulder 31, there are six bores arranged at the same angular pitch, which open into the interior 32 of the dispensing nozzle 10.
  • a compressed air connection 34 is screwed into the upper end of the receiving sleeve 23 and communicates with the entire interior of the receiving sleeve 23.
  • the housing 21 has a radial bore with an internal thread into which one Stud screw 35 is screwed in.
  • a longitudinal groove is arranged, into which the stud 35 engages with its inner end. This prevents the receiving sleeve 23 from rotating relative to the housing 21.
  • the robot automatically moves the automatic riveting machine up to a precisely predetermined distance to the riveting point. From here, the individual operating units such as the drilling unit, the application unit, etc. are then moved to the riveting point and the corresponding operations are carried out. If an already installed rivet hole is to be prepared by using the sealing compound to place a rivet, the holding bracket is already in the working position, whereas the application unit 1 is still in the rest position according to FIG. 1. Then the application head 6 is moved by means of the guide 3 exactly through the rivet hole for the predetermined distance. The application head 6 then carries out a delivery movement on the basis of a corresponding signal.
  • the dispensing nozzle 10 is first moved toward the component by means of the transverse guide 7 until the shoulder 31 has approached the edge of the rivet bore up to a predetermined, defined air gap. Then the application head 6 returns to its rest position without staying in the dispensing position.
  • the centering mandrel 30 is immersed in the rivet bore and thus aligns the application head 6 precisely with the rivet bore. If it should happen due to a defect that the centering pin 30 touches the edge of a hole, damage to the component due to the spring 24 is avoided, which then acts as a force limiter.
  • the dosing of the sealing compound takes place by supplying compressed air via the compressed air connection 34 and takes place in good time before the application head 6 reaches its dispensing position.
  • the compressed air introduced acts on the sealing compound in the cartridge 8 and presses it out through the bores 33, so that six balls consisting of sealing compound appear on the shoulder 31.
  • the amount dispensed i.e. the size of the balls, can be set precisely via the amount and duration of the pressure.
  • the sealing compound present in the balls is brought into contact with the edge of the rivet hole and distributed on account of the shoulder 31.
  • the gap between the shoulder 31 and the component takes up the sealing compound and causes it not to be squeezed outwards.
  • the timely execution of the dosing process is very important as it takes a certain amount of time. In order to ensure that the dosing process is completed before the delivery position is reached, this can possibly already be started while the relevant rivet hole is still being drilled.
  • the decisive parameters can be determined experimentally and taken into account in the control program of the riveting machine. After the sealant has been applied as described above, the rivet in question can be inserted into the rivet hole. used and squeezed.
  • the application unit can also be used to apply other materials, for example an adhesive.
