    The invention relates to a method and a device for the positioned holding of a laminated core together with at least one layer accommodated in the laminated core from a plurality of conductor elements arranged over the circumference of the laminated core and designed as rods, for forming a stator or a rotor of an electrical machine.
    US 2,270,472 A describes a system for producing a part of an electrical machine, in particular a rotor, in which the conductor elements are formed by so-called hairpins. Those free end sections which are later to be connected to form an electrical winding are to be deformed in circumferentially opposite directions before they are connected. In order to avoid damaging the insulation of the conductor elements and a separate insulating layer of the laminated core during this shaping process, ends of support fingers are respectively moved into the free spaces between the conductor elements. The support fingers rest on the end face formed by the laminated core. During the mutual shaping process of the end sections of the conductor elements, the individual supporting fingers serve as a bending support for the conductor elements.
    The object of the present invention was to provide a method and a device by means of which a user is able to achieve a positionally secure and bilateral mounting of the laminated core together with the conductor elements accommodated therein.
    This object is achieved by a method and a device according to the claims.

    The method according to the invention serves to hold a laminated core together with at least one layer accommodated in the laminated core from a plurality of conductor elements arranged around the circumference of the laminated core and designed as rods, to form a stator or a rotor of an electrical machine and comprises the following steps:
    - Provision of the laminated core from a plurality of sheet metal lamellae lying directly against one another and defining a longitudinal axis, wherein a plurality of receiving grooves arranged over the circumference are arranged in the laminated core and the receiving grooves each extend between a first end face and a second end face, the receiving grooves for receiving line sections one electrical winding,
    - Providing the rod-shaped conductor elements each with a first end section and a second end section spaced apart therefrom, the conductor elements serving to form the electrical winding and the conductor elements being formed with a rod length which is greater than a thickness of the laminated core between its first end face and its second face,
    Introduction of at least one of the conductor elements into several of the receiving grooves,
    - Positioned alignment of the conductor elements in the axial direction with respect to at least one of the two end faces of the laminated core, wherein the first end face of each of the first end sections and the second end sections each project beyond the second end face, and thereby
    - A plurality of first rod-shaped support elements distributed over the circumference are adjusted with their first ends facing the longitudinal axis from a position not covering an outer circumference of the laminated core in the direction of the longitudinal axis into a position partially covering the first end face in the direction of the longitudinal axis , so that the first ends are on the side facing away from the longitudinal axis and still outside of the conductor elements accommodated in the receiving grooves, and of the first support elements on their sides facing the laminated core there is a first / 45 oriented in the vertical direction
    N2017 / 25500 AT-00
    Stop surface is formed
    the laminated core together with the positioned aligned conductor elements is brought into contact with the longitudinal axis having a horizontal orientation in the axial direction with its first end face against the first stop surfaces of the first support elements,
    - A plurality of second rod-shaped support elements distributed over the circumference, with their second ends facing the longitudinal axis, are adjusted as far as possible from a position not covering an outer circumference of the laminated core in the direction of the longitudinal axis to a position partially covering the second end face in the direction of the longitudinal axis , so that the second ends are on the side facing away from the longitudinal axis and still outside of the conductor elements accommodated in the receiving grooves, and a second stop surface oriented in the vertical direction is formed by the second support elements on their sides facing the laminated core,
    the second support elements with their second stop faces are adjusted in the axial direction with respect to the longitudinal axis in the direction of the laminated core until a predominant number of the second stop faces rest on the second end face,
    that the first support elements are adjusted further in the direction of the longitudinal axis, and preferably at least one of the first support elements is adjusted into each free space in the circumferential direction between the conductor elements, and
    - The second support elements are also adjusted further in the direction of the longitudinal axis, and preferably at least one of the second support elements is adjusted in each free space located in the circumferential direction between the conductor elements.
    It is advantageous in the method steps selected here that firstly a positioned alignment of the laminated core together with the conductor elements accommodated therein can be carried out by means of the first supporting elements, because in the case of the An / 45 which is carried out in the axial direction and in a preferably horizontal alignment
    N2017 / 25500-AT-00 place a predetermined positioning of the first end face on the circumferentially arranged first stop faces. By further delivering and applying the second support elements, also in the axial direction with respect to the longitudinal axis of the laminated core, a sufficient further fixing of the position of the entire laminated core together with the conductor elements can already be achieved. If both the first support elements and the second support elements are then adjusted into the free spaces located between the conductor elements, a sufficient positional fixation of the conductor elements and of the laminated core can already be achieved. Thus, by means of the method steps, possibly using the device for holding the laminated core in position, a secure position fixation of the laminated core within the apparatus can be achieved without further device elements.
    Furthermore, a procedure is advantageous in which the first support elements and / or the second support elements are adjusted so far into the free spaces located in the circumferential direction between the conductor elements that the free spaces between the individual conductor elements are completely or at least almost completely filled. As a result, almost to complete clamping of the conductor elements arranged one behind the other in the circumferential direction can be achieved by the respective support elements arranged between them. Furthermore, the laminated core can also be carried along by the support elements resting on the conductor elements.
    A further advantageous procedure is characterized in that the adjustment of the first support elements and the second support elements is carried out in each case in the radial direction. A collision-free adjustment movement of the support elements into the free spaces between the conductor elements can thus be carried out safely and without collisions.
    A variant of the method is also advantageous, in which the laminated core, together with the positioned conductor elements, is received by a holding arm of a holding device before the first end face is placed against the first stop faces of the first supporting elements, and thereby on the holding arm be / 45
    N2017 / 25500-AT-00 sensitive and adjustable in the radial direction holding elements are pressed against an inner surface of the laminated core. This means that a central holder and subsequent handling processes of the laminated core together with the conductor elements can be carried out safely and precisely.
    Another procedure is characterized in that the positioned aligned conductor elements of the at least one layer are each acted upon by a pressure force built up by the at least one pressure element at their end sections projecting beyond the laminated core by at least one pressure element of a printing device that is adjustable in the radial direction and thus in the direction of the longitudinal extent the grooves are held relatively positioned with respect to the laminated core. A relative displacement of the conductor elements already accommodated in the receiving grooves with respect to the laminated core can thus be reliably prevented during the handling operations to be carried out. This is particularly the case if, starting from a position of the longitudinal axis of the laminated core that has a vertical orientation, it is to be pivoted into a horizontal position.
    Furthermore, a procedure is advantageous in which the laminated core, together with the positioned conductor elements, is positioned in the circumferential direction with respect to a desired position before its first end face is placed against the first stop faces of the first support elements. This means that each laminated core as well as the conductor elements already contained therein are received in the device in the same aligned position and this unit can, after the holding and clamping process have been carried out, be brought to a subsequent processing station, such as a deformation station for the end sections of the conductor elements, or be promoted.
    A further advantageous procedure is characterized in that the laminated core, together with the aligned conductor elements, pivots from a position of the longitudinal axis having a vertical orientation to the position of the longitudinal axis having a horizontal orientation before the first end face is placed against the first stop elements / 45
    N2017 / 25500-AT-00 will. Gravity-assisted positioning of the individual conductor elements within the laminated core can thus preferably take place automatically. This can also prevent the laminated core from rolling away during its transport movement between the individual work stations.
    A variant of the method is also advantageous in which the first support elements are each arranged or formed at least in pairs on a first slide element and the second support elements are each arranged at least in pairs on a second slide element. The number of adjustment mechanisms for the support elements can thus be reduced.
    Another procedure is characterized in that a first holding attachment is arranged or formed on the first support elements, in particular on the first slide elements, and on the second support elements, in particular on the second slide elements, a second holding attachment is arranged or formed. This creates the possibility of also being able to exert an additional and direct clamping action on the laminated core starting from the support elements or the sliding elements. The holding lugs are arranged or designed such that they come to rest on the outer circumference or on the outer circumferential surface of the laminated core.
    Furthermore, a procedure is advantageous in which after the application and support of the laminated core with its first end face on the first stop surfaces of the first supporting elements and in the circumferential direction of the first supporting elements in the free spaces between the conductive elements, the laminated core together with the conductive elements of the first support elements and / or the first holding approaches is held clamped. Depending on the dimensioning of the support elements and the radial arrangement of the retaining lugs, the clamping effect on the laminated core and / or the conductor elements can thus be determined exactly beforehand.
    A further advantageous procedure is characterized in that after the second support elements have been axially applied and supported with their second stop surfaces on the second end face of the laminated core and even before / 45
    N2017 / 25500-AT-00 further radial adjustment movement of the second support elements into the free spaces between the conductor elements or after this adjustment movement the holding elements pressed against the inner surface of the laminated core are moved away from the inner surface and the holding arm of the holding device from the inside of the laminated core in the axial direction Direction is adjusted. Depending on the chronological sequence of the clamping and release movements, a secure and collision-free adjustment of the individual support elements into the respective free spaces between the conductor elements can also be ensured in the area of the second holding unit with the second support elements.
    A variant of the method is also advantageous, in which after the axial support and support of the second support elements with their second stop surfaces on the second end face of the laminated core and in the circumferential direction of the second supporting elements in the free spaces between the conductive elements, the laminated core together with the conductive elements is held clamped by the second support elements and / or the second holding approaches. A secure and bilaterally positioned mounting and clamping of the laminated core and / or the conductor elements can thus be achieved.
    Another procedure is characterized in that the first support elements, in particular the first slide elements, are adjusted in the radial direction by a first drive device, in particular a cylinder-piston arrangement, a servo drive, and the second support elements, in particular the second slide elements, by a second one Drive device, in particular a cylinder-piston arrangement, a servo drive, can also be adjusted in the radial direction. Depending on the choice of the drive medium, the required drive force for the individual adjustment movements can thus be precisely predetermined and applied.
    A further advantageous procedure is characterized in that the first support elements, in particular the first slide elements, are arranged in a fixed position in the axial direction and a reference plane with a vertical orientation is formed by the first stop surfaces. With this a / 45
    N2017 / 25500-AT-00 exact reference plane of the first stop surfaces of the first support elements for the first end face of the laminated core to be attached to it.
    A method variant is also advantageous in which at least the second support elements, in particular at least the second slide elements, are adjustable in the axial direction with respect to the first support elements, in particular with respect to the first slide elements. It is therefore easy to take into account tolerance-related deviations in the thickness of the laminated core by appropriate adjustment processes. Furthermore, laminated cores with different dimensions can also be kept positioned in the device.
    Another procedure is characterized in that at least the second support elements, in particular the second slide elements, are adjusted jointly in the axial direction by a third drive device, in particular a cylinder-piston arrangement, a servo drive. In this way, a pressing force, predetermined in the axial direction, of the second holding unit with the second support elements can be exerted on the laminated core, and thus a clamping force acting in the axial direction can also be built up.
    Another procedure is characterized in that the laminated core located in the axial direction between the first support elements and the second support elements is pressed in the axial direction by the second support elements onto the first support elements. Due to the extensive pressing of the support elements on the laminated core, this can already be kept aligned in a secure exact position by the support elements arranged on both sides.
    If an axial distance in the normal direction between the first and second stop surfaces is determined in the case of a laminated core located between the first supporting elements and the second supporting elements and when the first stop surfaces are in contact with the first end surface and the second stop surface on the second end surface of the laminated core, this can be done by means of a measuring means assigned to the support elements or at least one of the holding units or a measuring arrangement determines the exact thickness of the laminated core in the axial direction
    N2017 / 25500-AT-00 den. Due to minimal fluctuations in the sheet metal thickness, the multiple stacking of the individual sheet metal lamellae can lead to fluctuations in the overall thickness or overall thickness of the sheet metal stack. This means that the exact thickness or thickness can always be determined for each individual laminated core without additional work steps.
    Furthermore, a procedure is advantageous in which the laminated core, which is positioned by the first and second support elements, is brought, at least together with the support elements, to a subsequent forming station for forming the end sections of the conductor elements which each project over the two end faces. This creates the possibility of being able to divide individual work steps over several processing stations in order to achieve high productivity of the entire system. This is because ongoing machining and / or forming operations can be carried out simultaneously.
    The device according to the invention serves to hold a laminated core together with at least one layer accommodated in the laminated core from a plurality of conductor elements arranged around the circumference of the laminated core and designed as rods, to form a stator or a rotor of an electrical machine, the device comprising:
    - A first holding unit with a plurality of first support elements arranged distributed over the circumference, a first stop surface oriented in the vertical direction being formed on the sides facing the laminated core of each of the first support elements and the first support elements being guided in an adjustable manner in the radial direction on the first holding unit are,
    - A second holding unit with a plurality of second rod-shaped support elements distributed over the circumference, a second stop surface oriented in the vertical direction being formed on the sides facing the laminated core of the second support elements and the second support elements in the radial direction on the second holding unit are adjustable, and / 45
    N2017 / 25500 AT-00
    - At least one of the two holding units is guided to be adjustable on a base frame in the normal direction with respect to the stop surfaces relative to the other holding unit.
    The advantage achieved in this way is that a positional alignment of the laminated core together with the conductor elements accommodated therein can be carried out first by means of the first supporting elements, because when the first end face is applied in the axial direction and in a preferably horizontal alignment to the circumferentially arranged first stop faces a predetermined positioning can already be achieved. By further delivering and applying the second support elements, also in the axial direction with respect to the longitudinal axis of the laminated core, a sufficient further fixing of the position of the entire laminated core together with the conductor elements can already be achieved. If both the first support elements and the second support elements are then adjusted into the free spaces located between the conductor elements, a sufficient positional fixation of the conductor elements and of the laminated core can already be achieved. Thus, by means of the method steps, possibly using the device for holding the laminated core in position, a secure position fixation of the laminated core within the apparatus can be achieved without further device elements.
    Furthermore, it can be advantageous if the first support elements are each arranged or formed at least in pairs on a first slide element and the second support elements are each arranged at least in pairs on a second slide element and the first slide elements are guided on the first holding unit and the second slide elements on the second holding unit , The number of adjustment mechanisms for the support elements can thus be reduced.
    Another embodiment is characterized in that a first holding attachment is arranged or formed on the first support elements, in particular on the first slide elements, and on the second support elements, in particular on the second slide elements, in each case a second holding attachment is arranged or formed, and the first holding attachments and the second retaining lugs on sides of the support elements, in particular the slide elements, facing each other, / 45
    N2017 / 25500-AT-00 are arranged. This creates the possibility of also being able to exert an additional and direct clamping action on the laminated core starting from the support elements or the sliding elements. The holding lugs are arranged or designed such that they come to rest on the outer circumference or on the outer circumferential surface of the laminated core.
    A further possible embodiment has the features that the first support elements, in particular the first slide elements, with a first drive device, in particular a cylinder-piston arrangement, a servo drive, and the second support elements, in particular the second slide elements, with a second drive device, in particular a cylinder Piston arrangement, a servo drive, are in drive connection and the adjustment movements can be carried out in the radial direction by the drive devices. Depending on the choice of the drive medium, the required drive force for the individual adjustment movements can thus be precisely predetermined and applied.
    A further embodiment provides that the first holding unit is arranged in a fixed position on the base frame and that a reference plane with a vertical orientation is formed from the first stop surfaces of the first support elements. An exact reference plane can thus be created by the first stop surfaces of the first support elements for the first end face of the laminated core to be placed thereon.
    Another embodiment is characterized in that at least the second holding unit is guided so as to be adjustable in the axial direction with respect to the first holding unit on the base frame and the second holding unit is in drive connection with a third drive device, in particular a cylinder-piston arrangement, a servo drive. In this way, a pressing force, predetermined in the axial direction, of the second holding unit with the second support elements can be exerted on the laminated core, and thus a clamping force acting in the axial direction can also be built up.

    To begin with, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, and the disclosures contained in the entire description can be applied analogously to the same parts with the same reference numerals or the same component names. The location information selected in the description, e.g. above, below, to the side, etc., referring to the figure described and illustrated immediately, and if the position is changed, these are to be applied accordingly to the new position.
    The term “in particular” is understood in the following to mean that it may be a more specific training or more detailed specification of an object or a method step, but does not necessarily have to represent a mandatory, preferred embodiment of the same or a mandatory procedure.
    1 shows a possible design of a stator 1 to form an electrical machine, not shown. However, it would also be possible to apply and carry out the following description and design in a manner analogous to that for a rotor for forming an electrical machine. The following description relates only to a stator 1, but can also relate to a rotor
    The assembly and a large number of production steps of the stator 1 can preferably be carried out automatically in a complex production system in a number of production stations, usually also fully automatically.
    Basically, the stator 1 comprises a laminated core 2 and a multiplicity of conductor elements 3, 4 to be accommodated therein for generating a magnetic rotating field by coils.
    / 45
    N2017 / 25500 AT-00
    In the present exemplary embodiment, the individual conductor elements 3, 4 are designed as straight rods in their undeformed starting position. The rods usually have a rectangular cross section up to a square cross section and a longitudinal extent and are formed from an electrically conductive material. Mostly it is a copper material. Therefore, these can also be called profile bars. In a known manner, the conductor elements 3, 4 can be surrounded with an insulating layer, not shown or designated, with the exception of contact regions formed thereon.
    To form electrical coils and windings formed therefrom, a plurality of receiving grooves 5 are arranged or formed in the laminated core 2 distributed over the circumference, in which at least one of the conductor elements 3, 4, but preferably at least two of the conductor elements 3, 4, is received or arranged is or are. The receiving grooves 5 can extend in the axial direction and preferably in a parallel orientation with respect to a longitudinal axis 6 defined by the laminated core 2. However, it would also be possible to choose a non-parallel arrangement of the receiving grooves 5 with the conductor elements 3, 4 to be accommodated therein. Thus, the receiving grooves 5 each extend in the direction of the longitudinal axis 6 between a first end face 7 and a second end face 8 arranged at a distance therefrom.
    The receiving grooves 5 each have a receiving groove cross section adapted to the cross-sectional dimension of the conductor element 3, 4 or, in the case of a plurality of conductor elements 3, 4 accommodated in the same receiving groove 5.
    The laminated core 2 is composed of a large number of individual laminations or laminated metal laminations which are electrically insulated from one another and is delimited in the direction of the longitudinal axis 6 by the first end face 7 and the second end face 8 arranged at a distance therefrom. The two end faces 7, 8 are preferably arranged parallel to one another and running in a plane oriented in the normal direction with respect to the longitudinal axis 6. In the present / 45
    N2017 / 25500 AT-00
    Exemplary embodiment forms the package from the individual sheets or the sheet metal lamellae a hollow cylinder with an inner surface and an outer surface.
    At least one of the conductor elements 3, 4 is preferably arranged in each of the receiving grooves 5, but preferably several, in particular two, three, four, five, six or even more conductor elements 3, 4. There may also be eight, ten, twelve or more conductor elements 3, 4 may be included. A conductor element 3, 4 is provided as a minimal variant, but in this exemplary embodiment two conductor elements 3, 4 are shown and described in one receiving groove 5. Thus, the conductor elements 3 arranged on the inside in the radial direction form a first layer 9 and the conductor elements 4 arranged on the outside in the radial direction form a second layer 10.
    Each of the conductor elements 3 and 4 comprises a first end section 11, 12 at its first end and a second end section 13, 14 at its opposite second end. In this exemplary embodiment, the first end sections 11, 12 protrude beyond the first end face 7 and the second End sections 13, 14 over the second end face 8 of the laminated core 2.
    The conductor elements 3, 4, which are accommodated in the laminated core 2 in the individual receiving grooves 5 and mostly still undeformed, are in the region of each of the end faces 7, 8 in their end sections 11, 12; 13, 14 in one of the subsequent manufacturing steps, in a known manner, twisted or interlaced in the circumferential direction in order to subsequently connect a first of the end sections 11 of the first or inner layer 9 to a correspondingly further first end section 11 of the second or outer layer 10 in an electrically conductive manner , The same can preferably also be carried out with the respective second end sections 13, 14 in the region of the second end face 8.
    Furthermore, it can also be advantageous if the individual conductor elements 3, 4, in addition to their insulating layer within the receiving grooves 5, are also preferably completely surrounded by their own insulating element 15.
    / 45
    N2017 / 25500 AT-00
    The feeding or the introduction of the individual conductor elements 3, 4 into the respective receiving grooves 5 can take place step by step or in cycles, the laminated core 2 with its longitudinal axis 6 preferably being in a horizontal orientation. Since the mostly still undeformed conductor elements 3, 4 are accommodated in the respective receiving grooves 5 so as to be longitudinally displaceable, the relative position of the conductor elements 3, 4 with respect to the laminated core 2 must be taken into account or ensured when transferring to a subsequent processing station or production station.
    In a positioning step to be carried out preferably before the transfer or transfer to the subsequent processing station or production station, the conductor elements 3, 4 can also be aligned in the axial direction with respect to one of the end faces 7, 8. This can e.g. in that the laminated core 2, together with the conductor elements 3, 4 already accommodated therein, is folded over from its preferably horizontal loading position into a vertical positioning position, in which the longitudinal axis 6 of the laminated core 2 has a vertical longitudinal orientation. The laminated core 2 can be supported on a positioning lug, the conductor elements 3, 4 preferably coming into contact with the individual receiving grooves 5 due to the force of gravity up to a preferably circumferential positioning element with one of their end sections 11, 12 or 13, 14. The distance between the positioning projection and the positioning element is to be selected in accordance with the predetermined projection of the ends of the conductor elements 3, 4 over one of the end faces 7, 8 of the laminated core 2.
    This transport position can e.g. on a workpiece carrier that can be moved between individual work stations.
    In this position of the longitudinal axis 6, which has a vertical orientation, the transfer or takeover to a subsequent processing station or production station is now to be carried out without changing the position of the conductor elements 3, 4 which have already been positioned in relation to the laminated core 2.

    N2017 / 25500 AT-00
    For this purpose, at least the method steps listed below for holding the laminated core 2 in position together with at least one layer 9, 10 accommodated in the laminated core 2, comprising a plurality of conductor elements 3, 4 arranged over the circumference of the laminated core 2 and designed as rods, for forming a stator 1 or a rotor electrical machine, optionally using a device, which is shown in FIGS. 2 to 8:
    The laminated core 2 is provided from a plurality of laminations directly adjacent to one another and defining a longitudinal axis 6 with a plurality of receiving grooves 5 distributed over the circumference. Furthermore, the rod-shaped conductor elements 3, 4, each with a first end section 11, 12 and one each spaced therefrom arranged second end portion 13, 14 to provide. Then the insertion or insertion of at least one of the conductor elements 3, 4 into preferably each of the receiving grooves 5 can be carried out. It is not absolutely necessary that at least one of the conductor elements 3, 4 must also be inserted into each of the receiving grooves 5. It may well be that at least one of the conductor elements 3, 4 is used in a predominant proportion of the receiving grooves 5, but none of the conductor elements 3, 4 is used in the plurality of receiving grooves 5 in individual ones. Therefore, several of the receiving grooves 5 are assumed, which are provided for receiving the at least one conductor element 3, 4.
    Once this has taken place, the conductor elements 3, 4 are to be aligned in the axial direction with respect to at least one of the two end faces 7, 8 of the laminated core 2, the first end face 7 of the first end sections 11, 12 of the conductor elements 3, 4 and the second end sections each 13, 14 the second end face 8 is towered over.
    A device 16 serves to hold the laminated core 2 together with the conductor elements 3, 4 accommodated therein, which device 16 can also be used as part of a production system (not shown in more detail) for the automated manufacture and joining of components of an electrical machine.

The first holding unit 17 in turn comprises a plurality of first rod-shaped or pin-shaped support elements distributed over the circumference of the laminated core 2 to be held
    20. Of these, a first stop surface 21 aligned in the vertical direction is formed on each of their sides facing the laminated core 2. Furthermore, the first support elements 20 are guided so as to be adjustable in the radial direction on the first holding unit 17.
    The second holding unit 18 likewise comprises a plurality of second rod-shaped or pin-shaped support elements 22 distributed over the circumference of the laminated core 2 to be held. Of these, a second stop surface 23 oriented in the vertical direction is formed on the sides thereof facing the laminated core 2. The second support elements 22 are adjustably guided on the second holding unit 18.
    In the present exemplary embodiment, provision is made for the first holding unit 17 to be arranged in a stationary manner on the base frame 19 and for a reference plane with a vertical orientation to be formed from the first stop surfaces 21 of the first support elements 20. However, an axial adjustment movement relative to the base frame 19 could also be provided. In order to be able to perform a relative adjustment movement of the second holding unit 18 in the axial direction with respect to the first holding unit 17, the second holding unit 18 is guided on the base frame 19 in an adjustable manner. In this way, the second support elements 22 can also be adjusted or displaced in the axial direction relative to the first support elements 20.
    The adjustment of the first support elements 20 and the second support elements 22 is preferably carried out in the radial direction on the holding units 17, 18. In the holding state of the laminated core 2, the first support elements 20 each have first ends 24 facing the longitudinal axis 6. Likewise, however, the second support elements 22 also have second ends 25 facing the longitudinal axis 6 in the holding state of the laminated core 2.

    As can now be seen better from FIG. 2, the first support elements 20 can each be arranged or formed at least in pairs on a common first slide element 26. Since the second support elements 22 are preferably of the same design as the first support elements 20, the second support elements 22 can also be arranged or formed at least in pairs on a common second slide element 27. At least here is understood to mean that more than two support elements 20 or 22 can each be arranged or formed on one of the slide elements 26 or 27. For example, three, four or five pieces of support elements 20 or 22 can also be provided on one of the slide elements 26 or 27. Although the support elements 20 or 22 are each present in pairs on a common slide element 26 or 27, one of the finger-like support elements 20 or 22 is preferably also adjusted into each of the free spaces between the conductor elements 3, 4.
    In this case, the first slide elements 26 on the first holding unit 17 and the second slide elements 27 on the second holding unit 18 are guided and adjustable in the radial direction. In order to be able to adjust the support elements 20, 22 in the circumferential direction between the receiving grooves 5 and thus also between the conductor elements 3, 4, and preferably also to achieve support or contact of the support elements 20, 22 with their longitudinal side surfaces, the surface shape of the support elements 20, 22 must be adapted to that of the free spaces or spaces. In the present exemplary embodiment, the support elements 20, 22 each have a tapering wedge shape in the direction of their ends 24, 25.
    In order to enable a possible additional clamping of the laminated core 2 by the first support elements 20 and / or the second support elements 22, a first holding attachment 28 and / or on the second support elements 22 can be provided on the first support elements 20, in particular on the first slide elements 26 , in particular on the second slide elements 27, a second retaining projection 29 can be arranged or formed. The first / 45 are arranged
    N2017 / 25500-AT-00 and second retaining lugs 28, 29 such that they are each facing the laminated core 2. The first retaining lugs 28 and the second retaining lugs 29 are thus arranged on sides of the support elements 20, 22, in particular the slide elements 26, 27, which face each other.
    A first drive device 30, in particular a cylinder-piston arrangement, a servo drive or the like, is provided for the relative positional adjustment of the first support elements 20, in particular the first slide elements 26. The position of the second support elements 22, in particular the second slide elements 27, can also be adjusted by means of a separate second drive device 31, in particular with a cylinder-piston arrangement, a servo drive or the like. For the sake of simplicity, the two drive devices 30, 31 are only indicated by means of arrows. A corresponding drive connection must be provided. Thus, in a known manner, an adjusting disk with guideways or guide extensions can be provided, which is in drive connection with one of the drive devices 30, 31 and also the support elements 20, 22, in particular the slide elements 26, 27, with the guideway or guide extensions or in operative connection stand.
    In order to be able to carry out the above-described axial adjustment movement of the second holding unit 17 together with the second support elements 22, a third drive device 37, in particular a cylinder-piston arrangement, a servo drive or the like, can be provided. It is also here for the sake of simplicity and better clarity that the third drive device 37 is also only indicated by arrows. Thus, the laminated core 2 located in the axial direction between the first support elements 20 and the second support elements 22 can be pressed against the first support elements 20 in the axial direction by the second support elements 22.
    The laminated core 2 together with the conductor elements 3, 4 accommodated therein can be e.g. can be transported between the individual work stations in the production system by means of a workpiece carrier. This workpiece carrier, which is not designated in any more detail, is shown in FIG. 2 in strichlier21 / 45
    N2017 / 25500-AT-00 ten lines indicated. In order to achieve a relative positioning of the conductor elements 3, 4 accommodated in the receiving grooves 5 due to gravity, the laminated core 2 can be placed and supported on the workpiece carrier with one of its end faces 7, 8. In this case, its longitudinal axis 6 has a vertical orientation. However, a horizontal alignment of the longitudinal axis 6 of the laminated core 2 is provided in the device 16. The laminated core 2 together with the conductor elements 3, 4 can thus be pivoted from the position of the longitudinal axis 6 having a vertical orientation to the position of the longitudinal axis 6 having a horizontal orientation.
    In order to avoid an unwanted relative displacement of the conductor elements 3, 4 in the receiving grooves 5 during this pivoting process, the positioned, aligned conductor elements 3, 4 of the at least one layer 9, 10 can each be located at their end sections 11, 12; 13, 14 are acted upon by at least one pressure element 32 of a pressure device 33 which is adjustable in the radial direction with a pressure force built up by the at least one pressure element 32. This makes it possible to be able to keep all conductor elements 3, 4 positioned relative to the laminated core 2 in the direction of the longitudinal extent of the receiving grooves 5. This is shown in simplified form in FIG. 3.
    3 also shows that the laminated core 2 for the pivoting process can be gripped and held clamped by a holding device 34 by means of a holding arm 35 as well as holding elements 36 which can be adjusted in the radial direction. A plurality of holding elements 36 can be provided, which are arranged distributed over the inner circumference of the laminated core 2 and are pressed against an inner surface of the laminated core 2 for holding. After capturing and holding the laminated core 2 together with the positioned conductor elements 3, 4, the laminated core 2 can be aligned positioned in the circumferential direction with respect to a desired position. This is to enable a collision-free insertion into the free spaces between the conductor elements 3, 4 for the introduction of the support elements 20, 22 and the holding process by the support elements 20, 22. An alignment mark, e.g. a notch or groove may be arranged or formed on the laminated core 2.

    N2017 / 25500 AT-00
    4 to 8, the sequence for the positioned holding of the laminated core 2 in the device 16 is shown in a highly schematic representation. It should be noted here that the chronological sequence of the individual work steps is only given as an example and that a different sequence can also be carried out. This can relate in particular to the delivery of the support elements 20, 22 in the radial direction and the axial direction and the application of the radial clamping force from the holding projections 28, 29 to the laminated core 2. Furthermore, the term “abut” or “put on” the support elements 20, 22 with their abutment surfaces 21, 23 on the respective end faces 7, 8 means only pressure-free, light support, in contrast to firm and force-related clamping. Therefore, in this state, it is not absolutely necessary for all of the support elements 20, 22 to bear against the respective end face 7, 8, but preferably a predominant number of them. In any case, this is more than 50% of the total number of support elements 20 or 22.
    The first holding unit 17 with the first support elements 20 is arranged in the region of the first end face 7. The second holding unit 18 with its second support elements 22 is arranged in the region of the second end face 8 of the laminated core 2. As already described above, the first support elements 20 each form the first stop surfaces 21 oriented in the vertical direction on their sides facing the laminated core 2. The laminated core 2 together with the conductor elements 3, 4 is moved towards the first stop surfaces 21 in the normal direction. In order to form a stop or a support surface, the first support elements 20, with their respective first ends 24 facing the longitudinal axis 6, are from a position not covering an outer circumference of the laminated core 2 in the direction of the longitudinal axis 6, into a position in which the first end surface 7 is in the direction of the To adjust the position overlapping the longitudinal axis 6 in sections so that the first ends 24 are on the side of the conductor elements 3, 4 facing away from the longitudinal axis 6 and are still outside the conductor elements 3, 4 accommodated in the receiving grooves 5.
    / 45
    N2017 / 25500 AT-00
    If the first support elements 20 are in this position, the laminated core 2 together with the positioned aligned conductor elements 3, 4 with the longitudinal axis 6 having a horizontal orientation can be placed and supported in the axial direction with its first end face 7 on the first stop faces 21 of the first support elements 20 , The first support elements 20, which are arranged and aligned in a radial manner with respect to a center, delimit a circular shape with their first ends 24 seen over the circumference, the longitudinal axis 6 of the laminated core 2 also being arranged to run in this center.
    If the first end face 7 of the laminated core 2 lies against the first stop faces 21, the first support elements 20 can be adjusted further in the direction of the longitudinal axis 6. Viewed in the circumferential direction, a free space is formed between each receiving groove 5 and thus also between the conductor elements 3, 4, into which at least one of the first support elements 20 is adjusted.
    If this has taken place, in the area of the second end face 8 the second support elements 22 of the second holding unit 18 with their second ends 25 facing the longitudinal axis 6 are likewise moved from a position which does not cover the outer circumference of the laminated core 2 in the direction of the longitudinal axis 6 into a position which covers the second end face 8 in the direction of the longitudinal axis 6 partially covering position so far adjusted that the second ends 25 are on the side facing away from the longitudinal axis 6 and still outside of the conductor elements 3, 4 received in the receiving grooves. As already described above, the second support elements 22 form the second stop surfaces 23, which are oriented in the vertical direction, on their sides facing the laminated core 2.
    After radial delivery of the second support elements 22, these are adjusted with their second stop surfaces 23 in the axial direction with respect to the longitudinal axis 6 in the direction of the laminated core until the second stop surfaces 23 come to rest on the second end face 8 of the laminated core 2. A small, sufficient clamping effect of the laminated core 2 can therefore already be between / 45
    N2017 / 25500-AT-00 the support elements 20, 22 can be achieved. Finally, the second support elements 22 are adjusted further in the direction of the longitudinal axis 6, the second support elements 22 likewise preferably being adjusted into any free space located in the circumferential direction between the conductor elements 3, 4.
    The first support elements 20 and / or the second support elements 22 can be moved into the free spaces in each case in the circumferential direction between the conductor elements 3, 4 to such an extent that the free spaces between individual conductor elements 3, 4 are completely or at least approximately completely removed from the support elements 20 and / or 22 can be filled in. A certain clamping of the conductor elements 3, 4 by the support elements 20, 22 can thus already be achieved.
    After placing and supporting the laminated core 2 with its first end face 7 on the first stop surfaces 21 of the first supporting elements 20 and in the position of the first supporting elements 20 in the circumferential direction between the conductor elements 3, 4, the laminated core 2 together with the Conductor elements 3, 4 are held clamped by the first support elements 20 and / or on the first retaining lugs 28. The lamination stack 2 is preferably held and clamped by means of the first retaining lugs 28, which are arranged or formed on the first support elements 20 or else on the first slide elements 26. However, the same also applies to the second holding unit 18 with its second support elements 22 and the second holding projections 29 arranged or formed thereon. Thus, after the second supporting elements 22 have been axially fitted and supported, their second abutment surfaces 23 can be attached to the second end face 8 of the laminated core 2 and in the position of the second support elements 22 in the circumferential direction in the free spaces between the conductor elements 3, 4, the laminated core 2 together with the conductor elements 3, 4 are held clamped by the second support elements 22 and / or the second holding projections 29 arranged or formed thereon become.

    N2017 / 25500 AT-00
    The laminated core 2, together with the conductor elements 3, 4, can be introduced into the device 16 by means of the holding device 34 and the holding elements 36 arranged circumferentially distributed on the holding arm 35. If the laminated core 2 is held clamped by the first support elements 20 and, if appropriate, the first holding lugs 28 and the second supporting elements 22 with their second stop surfaces 23 are also placed on the second end face 8 of the laminated core 2, the holding elements 36 pressed onto the inner surface of the laminated core 2 can this can be adjusted away and the holding arm 35 of the holding device 34 can be adjusted in the axial direction out of the interior of the laminated core 2. If the holding device 34 with the holding elements 36 is relaxed and moved out, the further radial adjustment movements of the second support elements 22 can take place in the free spaces between the conductor elements 3, 4.
    If the second holding projections 29 are also provided, they can also be brought into contact with the outer circumference of the laminated core 2 and the clamping of the laminated core 2 associated therewith.
    4 shows the situation in which the laminated core 2 together with the conductor elements 3, 4 has been brought to bear on the first stop surfaces 21 of the first support elements 20. The second support elements 22 are arranged with their second ends 25 at a distance from the outer circumference of the laminated core 2 in the radial direction.
    5 shows that the first support elements 20 have been moved into the free spaces between the conductor elements 3, 4 and also the first retaining lugs 28 have been brought into contact with the laminated core 2 and thus into a clamping holder on the laminated core 2 in the direction have been adjusted to the longitudinal axis 6. The second support elements 22 have been adjusted in the first intermediate position in the radial direction towards the longitudinal axis 6, but these are still located outside the second layer 10 of the outer conductor elements 4 here.
    / 45
    N2017 / 25500 AT-00
    6 shows the adjustment of the second support elements 22 in the direction of the first holding unit 17 with its first support elements 20 in the axial direction, so that its second stop surfaces 23 come to rest on the second end face 8 of the laminated core 2.
    7 then shows schematically that, on the one hand, the holding device 34 has been moved out of the interior of the laminated core 2 and the second support elements 22 have also been moved into the free spaces between the conductor elements 3, 4. It should be noted that the holding device 34 is preferably first moved out of the laminated core 2 before the second support elements 22 are moved into the free spaces between the conductor elements 3, 4. However, it would also be possible to first adjust the second support elements 22 into the free spaces between the conductor elements 3, 4 and, if necessary, to hold the laminated core 2 clamped with the second holding projections 29 arranged thereon before the laminated core 2 is released by the holding device 34 and this is adjusted out of the laminated core 2.
    In the operating state of the device 16 shown in FIG. 7, the radially fixed clamping of the laminated core 2 takes place both from the first holding unit 17 with the first support elements 20 and, if appropriate, the first holding projections 28 and also the second holding unit 18 with their second support elements 22 and, if appropriate the second holding lugs 29. Fixed clamping means that a high clamping force is exerted on the laminated core 2.
    Finally, it is also shown in FIG. 8 that, in addition to the radial tensioning and holding of the laminated core 2 by the support elements 20, 22 and, if appropriate, also the holding projections 28, 29, the laminated core 2 by the second holding unit 18, in particular the second supporting elements 22, pressed in the axial direction against the first holding unit 17 with the first support elements 20 arranged there and is thus also firmly clamped in this direction.
    Deviating from this, however, it would also be possible after the laminated core 2 with its first end face 7 has been placed against the first stop faces 21 of the first support elements 20 - see FIG. 4 below - the second support elements / 45
    N2017 / 25500-AT-00 in the first intermediate position in the radial direction towards the longitudinal axis 6 so that its second ends 25 are still outside of the conductor elements 3, 4 accommodated in the receiving grooves 5 - see FIG. 5 above. Then the second support elements 22 are then fed in the direction of the first holding unit 17 with its first support elements 20, so that its second stop surfaces 23 come to rest on the second end face 8 of the laminated core 2 - see FIG. 6 above.
    If both the first and second stop surfaces 21, 23 predominantly abut the respective end faces 7, 8 of the laminated core 2, the support elements 20, 22 are each adjusted into the free spaces between the conductor elements 3, 4. This can be done simultaneously (at the same time) or at different times. A too strong axial contact of the support elements 20, 22 on the laminated core 2 would lead to high adjustment forces of the support elements 20, 22 due to the friction. This should be avoided.
    The clamping of the laminated core 2 on its outer circumference by means of the retaining lugs 28, 29 can then be carried out additionally and optionally, but is not absolutely necessary.
    Since the finger-like support elements 20, 22, which are preferably arranged in pairs, can also build up a spring effect when viewed in the circumferential direction, clamping of at least some of the conductor elements 3, 4 by the support elements 20, 22 can thus be achieved as soon as these also extend far enough between them have been adjusted.
    Since even small sheet thickness fluctuations in the sheet metal laminations forming the sheet stack can result in different finished dimensions, it is possible in this firmly clamped position to determine the distance or the distance between the first stop faces 21 and the second stop faces 23. In this position of the laminated core 2, which is firmly clamped at least in the axial direction, a clamping force or compressive force is applied or built up, which is approximately the dead weight or the dead weight of the sheet / 45
    N2017 / 25500-AT-00 package 2 corresponds. For example, the dead weight or dead weight for smaller sizes has a value between 10 N and 300 N, for larger types even up to 2500 N and above. If at least this compressive force acts on the laminated core 2, the measurement of the total thickness is only then carried out.
    This can e.g. In this way, since the first holding unit 17 with its first support elements 20 preferably forms the reference plane or reference plane on the first stop surfaces 21, the position or position of the second holding unit 18 is determined relative to the first holding unit 17 by appropriate measuring means, and the actual information is given via this position Distance or the distance between the second stop surfaces 23 arranged at a distance from the first stop surfaces 21 can be determined. However, other known measuring methods or measuring means can also be used in order to be able to determine the distance or the distance between the first stop surfaces 21 and the second stop surfaces 23.
    If the laminated core 2 has also been axially clamped, the laminated core 2 positioned and clamped clamped by the first and second support elements 20, 22 and, if appropriate, the first and second retaining lugs 28, 29 can be held, at least together with the support elements 20, 22, on a subsequent, Forming station (not shown in more detail) for forming the end sections 11, 12 and 13, 14 of the conductor elements 3, 4, each projecting over the two end faces 7, 8.
    The exemplary embodiments show possible design variants, it being noted at this point that the invention is not restricted to the specially illustrated design variants of the same, but rather also various combinations of the individual design variants with one another are possible and this variation possibility is based on the teaching of technical action through the present invention Ability of the specialist working in this technical field.
