    The invention relates to a device for automated mounting of Gewindeeinsåtzen in components, which has a screwing device for screwing the threaded insert into a threaded bore of the provided component by means of a driving pin on the threaded insert and a striking device for separating said entrainment pin. In addition, the invention relates to a Gelenkachsroboter with such a device. The invention also pertains to a method for automated mounting of threaded inserts in components in which a component is provided which has at least one threaded bore, a threaded insert is screwed into the threaded bore by means of a driver pin on the threaded insert and the said driver pin is cut off.
    Such a device and such a method are basically known from the prior art. For example, DE 10 2013 222 455 A1 discloses a method for the automated mounting of threaded inserts in components, in which a component which has at least one threaded hole is provided at an automated assembly site of a mounting cell. In a further step, threaded inserts are fed to a single removal point and received there by a tool of an automatically controlled industrial robot. Then, the threaded insert is screwed by the industrial robot into the threaded bore of the component and a driving pin of the threaded insert optionally broken off.
    The threaded inserts used in DE 10 2013 222 455 A1 consist of a spirally wound profile wire which is hinged at one end to the middle in order to provide said driving pin. These types of threaded inserts are known, for example, under the trade name Helicoil and are used inter alia to provide resistant threads in aluminum components. The profile wire is usually made of steel, especially stainless steel, and is screwed into a threaded hole in the aluminum part. The special design significantly reduces the risk of breakage of the thread flanks.
    In accordance with the invention, a driver pin cut off on the bottom of a blind bore can be removed by automated turning of the component, in that the driver pin can fall out of the downwardly pointing opening of the threaded bore by gravity. In particular, the production of heavy and / or voluminous / bulky components but this considerably more difficult, since they can be rotated only with considerable technical effort. In addition, it is difficult, if not impossible, to determine whether the separated drive pins fall out of all the threaded holes. If, for example, twenty tapped holes are provided with threaded inserts, but only nineteen are tapped when they fall out, the determination of which tapped hole must be reworked is extremely easy. This applies in particular to components that can not or only very difficult to manipulate by hand.
    Alternatively, the severed driving pin may alternatively be removed from the threaded hole by blowing through a pneumatic tool which is formed by the industrial robot and which may be designed as a compressed air nozzle. The problem here is that the DruckluftdOse must be led to the bottom of the blind hole in order to generate an effective flow. However, the DruckluftdOse obstructed then the way of the separated Mitnehmer pin. If the compressed air pressure ηυΓθυββη stopped, there is no effective flow in the blind hole and the probability that a separated entrainment peg remains in the threaded hole, is relatively large, with the above-described consequences of a lengthy and mOhsamen troubleshooting.
    Another possibility disclosed in DE 10 2013 222 455 A1, the (still associated with the threaded insert) driving pin to grab by a suitable Greifwerk- tool and pull out by a pulling movement through the industrial robot from the threaded hole, the driving pin due to the pulling movement of the threaded insert is demolished. Especially with smaller diameters of the threaded holes, a secure grip of the journal pin is questionable, or a correspondingly fragile gripper can not withstand the high loads for a long time and then has to be maintained or exchanged.
    It is therefore an object of the invention to provide an improved apparatus and method for automatically mounting threaded inserts in components. In particular, the separated driving pins of the Gewindeeinsåtze in any position of the threaded hole and can be removed with high security.
    The object of the invention is achieved with a device of the aforementioned type, in addition comprising a magnet for removing the separated driving pin from the threaded bore.
    The object of the invention is also achieved with a Gelenkachsroboter or industrial robot, which has a device of the type mentioned.
    The object of the invention is finally solved with a method of the type mentioned, in which the separated driving pin is removed with the aid of a magnet from the threaded hole.
    The proposed Malinahmen eliminates a screwing the threaded insert in a Kopfiiber position respectively a rotation of the component in this position after the insertion of the threaded insert. Instead, the screwing of the threaded insert and the removal of the separated driving pin from the threaded hole can take place in any position, whereby in particular the production of heavy and / or voluminous / bulky components is facilitated. Even a fragile gripper or the less process-safe blowing out of the driving pin can be dispensed with. If the presented device on a
    Joint robot or industrial robots mounted, highly automated manufacturing operations can be performed.
    Advantageous embodiments and further developments of the invention will become apparent from the dependent claims and from the description in conjunction with the figures.
    It is beneficial if the magnet is designed as a permanent magnet. This results in a comparatively simple construction of the device for the automated mounting of threaded inserts.
    But it is also good if the magnet is designed as an electromagnet. This allows the magnetic field to be switched on and off. It is also particularly advantageous when a unipolar magnetic field is applied to the magnets designed as an electromagnet for holding the driving pin and an alternating field is applied to the magnet for releasing the driving pin. As a result, a magnetization of the magnet and / or is degraded on a standing in ma-gentically operative connection component. The release of the abge-separated drive pin succeeds in this way even better.
    It is also particularly favorable if the magnet is designed as a combination of a permanent magnet and an electromagnet. By brief energization of the electromagnet can be superimposed on the feide of the permanent magnet, a temporarres Feid, which neutralizes the feid of the permanent magnet. As a result, the power consumption of the device can be reduced because the electromagnet in principle only briefly during a disposal operation, ie when releasing the separated drive pin needs to be controlled.
    It is also favorable if a threaded insert consisting of stainless steel and / or austenitic steel is screwed into the threaded hole. Austenitic steel is generally not magnetic. The same applies to austenitic stainless steel, which is also not magnetic. In addition, there is also ferritic stainless steel, which is low magnetic. Thread inserts are often made of stainless steel, in particular non-magnetic austenitic steel, because of their rust-inhibiting properties. This suggests that the separated driver pin can not be removed from the threaded hole with the aid of a magnet. However, experiments have surprisingly shown that the non-magnetic steel becomes partially magetic due to the deformation. In particular, this applies to the relatively sharp bend of the journal, where the spiral shape of the wire merges into a straight piece that is bent radially inward. This phenomenon makes use of the invention, so that not only ferritic driving pins can be removed from the threaded hole, but also austenitic.
    It is also advantageous if the impact device has a movable Stos sel / crusher for separating said entrainment pin, which is operatively connected to the magnet. For example, the magnet can be arranged directly on the bump / crusher. The magnet may also have a through hole through which the bump / crusher passes, whereby the bump / crusher can be moved relative to the magnet.
    It is particularly advantageous if the bump / breaker consists of soft magnetic material. In this way, the magnetic field generated by the magnet can be well passed through the bump / crusher to the receiving area for the abge separated drive pin.
    Advantageously, the device for automated mounting of thread inserts additionally has a suction device acting in the region of the impact device. Accordingly, it is advantageous if the separated entrainment pin is sucked out of the threaded hole after removal. As a result, the separated driving pin can be removed quickly and safely from the threaded hole. As a result of the fact that the extraction process is carried out essentially θυββΓίΐθ ^ the threaded bore, air can nachström after the separated driving pin and this ιτιίίΓβίββη in the air flow.
    It is advantageous in the above context, when the magnetic field is switched off during the suction or an alternating field is applied to the magnet. By these measures, the suction can be improved, especially when the holding force of the magnet is relatively high. In addition to the single-off switching can also be provided that an alternating field is applied to the magnet to reduce magnetization of the magnet and / or on ei-nem in magentically active connection component.
    In addition, it is beneficial if the suction device has an ejector / volume flow amplifier with a compressed air connection, and the ejector / volume flow amplifier is connected on the intake side to a receiving region of the impact device. In this way, the suction device comes with virtually no moving parts, making them very robust and can cause no or little damage in the suction device with high driving speed Mitnehmerzapfen. A volume flow enhancer is available, for example, from the company www.smc.eu.
    It is furthermore particularly advantageous if the device for automated mounting of threaded inserts has a metal detector arranged in the region of a disposal pipeline of the suction device. Accordingly, it is advantageous if the suction of the separated entrainment pin is monitored by means of a sensor which is arranged in the region of a disposal pipeline. As a result, it is possible to be sure that the severed driving pin has actually been removed from the threaded hole. If necessary, the removal process can be repeated and / or an alarm can be triggered. If necessary, the detection of a driving pin can also trigger the (re) activation of the magnet if it has been switched off during the extraction process.
    In a further advantageous embodiment of the presented device, the impact device on a movable Stossel / crusher, as well as an associated with this Stossel / crusher Pneumatikzyl indians. By means of the pneumatic cylinder, relatively hard impacts can be carried out, with the aid of which the driving pin can be separated from the threaded insert.
    In a particularly advantageous embodiment, a displacement mechanism is provided which is adapted to displace the pneumatic cylinder along the direction of movement of the pusher / crusher. In this way, the position of the pusher / crusher can be adapted to the depth of the threaded hole during the execution of a strike. For example, the Schlagvor-direction can be adjusted so that the maximum impact force is achieved in the field of Mitnehmer pin and / or so that the Stossel / crusher not durchschlågt to the bottom of the blind hole but taking into account the thickness of the separated drive pin in time for Reason of the blind hole stops. The engine to the displacement mechanism can be ausgefQhrt relatively poor performance, since with this yes no Schlåge ausfQhrt must. For example, the drive may be formed by a geared motor with a threaded spindle. It is also advantageous if a feed device is provided for feeding the threaded inserts. For example, the Zufuhr device can be formed by a drive for a belt on which the Gewindeeinsätze are attached. It would also be conceivable, for example, for a motor-driven, carousel-type magazine in which a plurality of threaded inserts to be installed can be accommodated. It is also advantageous if the supply of the threaded inserts takes place - similar to a pneumatic tube system - via a hose system and compressed air. βοΙιΙίββΙίοΐΊ it is also advantageous if the screwing device and the impact device are arranged on a rotary plate which is rotatably mounted in a base plate. In this way, the screwing device and the Schlagvor-direction can be brought by rotation of the rotary plate alternately in the region of the threaded bore. Due to the design so a turret is realized-light.
    It should be noted at this point that the embodiments disclosed for the presented device and the resulting advantages of the same kind relate to the method presented, and vice versa.
    For a better understanding of the invention, this will be explained more closely with reference to the following figures.
    In each case, in a highly simplified, schematic representation:
    1 shows an exemplary and schematically illustrated device for the automated assembly of threaded inserts;
    Fig. 2, the impact device and suction device of the apparatus of Fig. 1 in detail and
    3 shows a device mounted on an articulated-arm robot or industrial robot for the automated mounting of threaded inserts.
    By way of introduction, it should be noted that in the variously described embodiments, like parts have been given the same reference numerals and parts, and the disclosures contained throughout the specification can be more particularly applied to like parts having like reference numerals and like parts , Also, the positional items selected in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and sinngerr ^ at a La ge change to the new location to transfer.
    Fig. 1 shows an exemplified device 1 for automated mounting of Gewindeeinsåtzen 2 in components 3 in side view, Fig. 2 the indicated in FIG. 1 section AA. The device 1 comprises a screwing device 4 for screwing the threaded insert 2 into a threaded bore 5 of the provided component 3 by means of a driving pin 6 on the threaded insert 2 and a striking device 7 for separating the said driving pin 6. The device 1 furthermore comprises a magnet 8 for removing the separated entrainment pin 6 from the threaded hole 5.
    In the presented device 1, the impact device 7 has a movable baffle / crusher 9 for separating said entrainment spigot 6, which is operatively connected to the magnet 8. In the concrete example, it is assumed that the magnet 8 is mounted directly on the bump / crusher 9 and is therefore also moved during a linear movement of the bump / crusher 9. However, the magnet 8 may also have a through hole through which the bump / crusher 9 passes, whereby the bump / crusher 9 can be moved relative to the magnet 8. The magnet 8 then remains in position during the movement of the bump / crusher 9. In both cases, the magnetic field generated by the magnet 8 is passed to the tip or respectively to the receiving region 10 of the bump / crusher 9, since the bump / crusher 9 acts as a yoke. It is particularly advantageous in this context when the bump / crusher 9 is made of soft magnetic material. In this way, the magnetic field generated by the magnet 8 can be passed particularly well to the receiving area 10 for the separated driving pin 6.
    The magnet 8 is formed in this example as an electromagnet, whereby the magnetic field can be switched on and off, or unipolar and bipolar magnetic fields can be generated. It is also conceivable, of course, that the magnet 8 is designed as a permanent magnet. This results in a comparatively simple construction of the device 1.
    It is also conceivable that the magnet 8 is formed as a combination of a permanent magnet and an electromagnet. By brief energization of the electromagnet can be superimposed on the feide of the permanent magnet, a temporarres Feid, which neutralizes the feid of the permanent magnet. As a result, the power consumption of the device 1 can be reduced, since the electromagnet in principle needs only briefly to throw off the separated Mitneh-merzapfens 6 activated.
    To perform a strike, the impact device 7 comprises a pneumatic cylinder 11 connected to the bump / crusher 9. With the aid of the pneumatic cylinder 11, relatively hard impacts can be carried out with the aid of which the driving pin 6 can be reliably separated from the threaded insert 2. For the return of the bump / crusher 9, a spring 12 is provided in this example. Of course, it is also conceivable that the bump / crusher 9 is guided in another way, for example by the pneumatic cylinder 11 being executed double-acting.
    Finally, the device 1 has a suction device 13 acting in the region of the impact device 7. FIGS. 1 and 2 show a disposal pipeline 14 of the suction device 13, a metal detector 15 arranged on the disposal pipeline 14, and a vacuum generator 16 connected to the disposal pipeline 14. The suction device 13 is located on the suction side in a head section 17, through which the bumper / crusher 9 is guided. The disposal pipe 14 also leads to a disposal container (not shown).
    In the illustrated example, the vacuum generator 16 is designed as an ejector or volume flow amplifier and has a compressed air connection 18. The vacuum generator can, however, for example also be designed as a suction ventilator and, in particular, be arranged near the disposal container. In this case, the illustrated part of the disposal pipe 14 acts as a suction line. If the vacuum generator, as shown, in the region of the bump / crusher 9, the disposal pipe 14 acts as a pressure line. Le-diglich lying in the flow direction before the compressed air port 18 part acts suction.
    If, as in the present example, an EjektorA / olumenstromverstÃrrker 16 pre-see, the suction device 13 comes with virtually no moving parts, which is very robust and move at high speed-the driving pin 6 in the suction 13 little or no Can cause damage.
    Finally, the device 1 comprises a pneumatic adjusting / pressure cylinder 19, with which the screwing device 4 and the impact device 7 can be moved axially.
    The function of the illustrated device 1 is as follows:
    With the help of the screw 4, the threaded insert 6 is screwed into the tapped hole 5 tion. The process is known per se, for example from DE 10 2013 222 455 A1, and is therefore not explained in detail. In a nåchs-th step, the driving pin 6, which is the screwing device 4 for the formschIOssige Clbertragung the rotational movement, separated from the threaded insert 6. For this purpose, the impact device 7 is positioned above the threaded bore 5 and placed on the component 3 with the aid of the adjustment / pressure cylinder 19 (note: in FIG. 2, the impact device 7 or the head piece 17 is not yet on the component) Component 3 attached). As a result, a blow is made with the pneumatic cylinder 11. In this blow, the Stos sel / crusher 9 is moved into the threaded hole 5, until it meets the drive pin 6 and separates it.
    In the example presented, the adjustment of the impact device 7 takes place pneumatically with the adjusting / pressure cylinder 19. Positioning error can advantageously be compensated for when placed on the component 3 in this way, since the adjusting / pressure cylinder 19 also acts as an air spring and the Kopfstuck 7 with more or less constant force on the component 3 driickt. Of course, it is also possible to provide another drive for said adjustment, for example an electric or hydraulic drive. The aforementioned adjustment can be completely eliminated. The placement of the head stiicks 17 on the component 3 is then concerned, for example (only) by the drive of a robot (see also Fig. 3). Of course, the adjusting / pressure cylinder 19 can also be used in combination with a robot.
    In a further step, the separated driving pin 6 is lifted with the Stos sel / crusher 9 from the threaded hole 5. The magnetic field generated by the magnet 8 is thereby passed through the långiichen part of the Stossel / crusher 9 through to the receiving area 10, whereby the separated entrainment pin 6 adheres to the Stossel / crusher 9.
    As soon as the separated entrainment pin 6, after removal from the threaded bore 5, flows into the airflow of the suction device 13, it is sucked into the disposal conduit 14. As a result, the separated carrier pin 6 can be removed quickly and safely from the area of the threaded hole 5. In support of this process, the magnet 8 can be turned off briefly to reduce the adhesive force of the driving pin on Stossel / crusher 9. Alternatively, it can also be provided that an alternating field is applied to the magnet 8 in order to reduce a magnetization of the magnet and / or of the bump / crusher 9.
    The correct suction of the separated entrainment pin 6 is monitored by means of the sensor / metal detector 15. If necessary, the removal process can be repeated and / or an alarm can be triggered. Optionally, the detection of the entrainment pin 6 also the (re) activation of the magnet 8 auslös-loose when thisfurden the suction was turned off.
    In general, it should be noted that the suction device 13 can be permanently in operation, or only if necessary, the "break" when the bump / crusher 9 is in its upper position. If the suction device 13 is constantly in operation, then it is advantageous if the piston rod of the pusher / crusher 9 is hollow-drilled and connected to an opening 20. In this way, the opening 20 and the bore in the bobbin / crusher 9 can flow after the secondary air when the impact device 7 is placed on the component 3. In principle, however, it is also possible for air to be sucked out via the opening 20, thus improving the adhesion of the severed entrainment pin 6 on the stossel / crusher 9. In this case, air overflows the gap between the headstock 17 and the component 3. The above-proposed, intermittent operation is particularly useful when using an ejector / VolumenstromverstÄrkers 16, since it can be quickly activated and deactivated by opening a valve in the compressed air supply. Thereby, the power consumption of the device 1 can be lowered.
    The same applies to the magnet 8, which can either be permanently activated, or only when required during the extraction of the separated driving pin 6. The suction device 7 and the magnet 8 (and the pneumatic cylinder 11) can do this by a control, not shown. be controlled.
    The extraction by means of the suction device 13 is advantageous but not mandatory. It is also conceivable that the impact device 7 is moved over a Abfallbehål-ter and the driving pin 6 is dropped there. For this purpose, the solenoid 8 can be turned off again, or it is switched from a unipo-magnetic field to a bipolar magnetic field to reduce magnetization of the magnet 8 and the standing in magenta active connection shock / crusher 9.
    In order to be able to adapt the position of the pusher / crusher 9 during the execution of a strike to the depth of the threaded bore 5, a displacement mechanism may be provided which ver the pneumatic cylinder 11 along the direction of movement of the pusher / crusher 9 against the headstock 17 ver pushes (whereas the adjusting / pressure cylinder 19 moves the pneumatic cylinder 11 together with the Kopfstiick 17). For example, a spindle motor may be provided for this purpose (not shown). For example, the impact device 7 can be adjusted so that the maximum impact force is achieved in the range of the driving pin 6 and / or so that the bump / crusher 9 does not durchschlågt to the bottom of the blind hole 5, but taking into account the thickness of the separated entrainment pin 6 in a timely manner stops in front of the bottom of the blind hole 5. The spindle motor can be designed to be relatively weak, since it does not execute any blows. Of course, the displacement mechanism can also be driven differently than shown, for example pneumatically or hydraulically.
    In the previous examples, it was assumed that the magnet 8 is located at the rear of the bump / crusher 9. This is advantageous, but not mandatory. Rather, it is also conceivable that the magnet 8, in particular a permanent magnet, is embedded in the receiving region 10 of the bump / crusher 9. When selecting the material for the bump / crusher 9, the properties for conducting a magnetic field can then be neglected.
    It is also conceivable that a separate lift is provided, with the help of the driving pin 6 can be removed from the threaded hole 5. After knocking off the driving pin 6 with the impact device 7 of the bump / crusher 9 is lifted in this case from the threaded hole 5 and then the lifter Qber the threaded hole 5 is positioned. In a further step, the driving pin 6 is removed with the lifter from the thread guide 5. With regard to the magnetic lifting with the pestle / crusher 9, this also applies to the separate lifter.
    3 now shows a joint-axis robot 21 or industrial robot which has a plurality of joint segments and a device 1 of the type described as the machining head. This allows highly automated production processes to be carried out. In particular, a plurality of threaded sockets 6 can be rationally mounted on a component 3.
    In particular, in cooperation with a robot 21, it is advantageous if the device 1 has a Zufdhrvorrichtung for Zuf Zufhrung the Gewindeeinsätze 6 (not shown). For example, the feeder may be formed by a drive for a belt on which the threaded inserts 6 are mounted. It would also be conceivable, for example, for a motor-driven, carousel-type magazine in which a plurality of threaded inserts 6 to be installed can be accommodated. It is also advantageous if the thread insert 6 is fed - similar to a pneumatic tube system - via a hose system and compressed air.
    It is also advantageous, if at least the screwing device 4 and the impact device 7 are arranged on a rotary plate which is rotatably mounted in a base plate. In this way, the screwing device 4 and the impact device 7 can be brought by rotation of the rotary plate alternately in the loading area of the threaded hole 5. Due to the design so a turret is realized.
    The Ausfähhrungsbeispiele show a possible Ausfåhrungsvariante a device 1, respectively, a robot 21 for automated mounting of threaded inserts 2 in components 3, it being noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but instead Rather, various combinations of the individual variants are possible with each other and this possibility of variation due to the doctrine of technical action by current invention in the Konnen the skilled in this technical field. Thus, also all conceivable variants of embodiment, which are possible by combinations of individual details of the illustrated and described embodiments, are included in the scope of protection.
    The proposed ΜθβηθΙιηηβη eliminates screwing the threaded insert 2 in a head-over position or a rotation of the component 3 in this position after screwing the threaded insert 6, as taught in DE 10 2013 222 455 A1. Instead, the screwing of the threaded insert 2 and the removal of the separated driving pin 6 from the threaded hole 5 can take place in any position, whereby in particular the production of heavy and / or voluminous / bulky components 3 is facilitated.
    In general, the presented device 1 or the proposed method are also suitable for threaded inserts 2 made of stainless steel and / or austenitic steel. Austenitic steel is generally not magnetic. The same applies to austenitic stainless steel, which is also non-magnetic. Thread inserts 2 are frequently made of stainless steel, in particular non-magnetic austenitic steel, because of their rust-inhibiting properties.
    Although a soleher threaded insert 2 is not magnetic or at best very weakly magnetic and can not actually be handled reliably with a magnet, experiments have surprisingly revealed that the non-magnetic steel is partially magnetic by the deformation. This applies in particular to the relatively sharp bend of the driving pin 6, at which the spiral-shaped course of the wire in the straight piece passes over, which is bent radially inwardly. As a result, not only are ferritic carrier pins 6 removed from the threaded hole 5, but also austenitic ones.
    In particular, it is also noted that the illustrated device 1 or the robot 21 in the reality may also comprise more or fewer components than shown. In some cases, the device 1 and the robot 21 or their components can also be shown unmounted and / or enlarged and / or reduced in size.
    The problem underlying the independent inventive solutions can be seen from the description.
