[0001] Riveting tool in compact design
[0002] The present disclosure relates to a riveting tool and, more particularly, to a blind rivet setting tool, a blind rivet nut setting tool and a blind rivet screw setting tool.
[0003] Riveting tools are typically used to create a riveted joint between two or more materials, such as sheet metal, at a junction where the materials lie against one another. To create the riveted joint, a plastically deformable, usually cylindrical connecting element, generally referred to as a rivet, is used. The rivet usually has a prefabricated setting head at one end. To create the riveted joint, the rivet is inserted into a connecting hole provided at the joint up to the setting head and then the other end of the rivet is plastically deformed into a closing head.
[0004] Riveting tools can also be used to add threads to thin-walled components. Rivet nuts or rivet bolts are used for this purpose, combining a rivet with a threaded element. The rivet nuts or rivet bolts are inserted into a prefabricated rivet hole in the component, and then a portion of the rivet is plastically formed into a closing head.
[0005] Conventional riveting tools usually comprise a riveting tool which is designed to effect a plastic deformation which forms the closing head. To actuate the riveting tool, the riveting tools have a drive device accommodated in a device housing. The drive device is often electromechanical and comprises, for example, an electric motor and a spindle gear designed as a ball screw drive with a threaded spindle and a spindle nut. The spindle nut is usually driven by the electric motor and the threaded spindle is secured against twisting by torque arms so that when the spindle nut rotates, the threaded spindle moves axially and in doing so acts on the riveting tool.
[0006] Such a riveting tool is described in EP 0 527 414 A1. The riveting tool is designed and configured for blind riveting and is equipped to pull a rivet mandrel out of the rivet body of a blind rivet by exerting a pulling movement, compressing the rivet body to create a closing head. The pulling movement is carried out by a mandrel holder which is driven by the drive device via the threaded spindle and to which the rivet mandrel is fixed. The mandrel holder is accommodated in a tool housing and is held therein so as to be movable relative to a mouthpiece fastened to the tool housing in order to carry out the pulling movement. The rivet mandrel is inserted into the tool housing via the mouthpiece as far as the mandrel holder, and the riveting tool is then placed on top of this at the point to be riveted.
[0007] In the riveting tool, the nosepiece is mounted above the tool housing on an axial bearing designed as a thrust bearing, which in turn is supported on the spindle nut of the drive unit. The tool housing is screwed to a bearing cup that accommodates the axial bearing. However, this type of mounting is relatively bulky in the direction of movement of the mandrel holder and complicates the use of the riveting tool.
[0008] In the course of ongoing development, there is therefore a need to improve the compactness of a riveting tool. This is based on the expectation that improved compactness will make it easier to reach hard-to-reach riveting locations and place a rivet there. Furthermore, it is expected that improved compactness will make the riveting tool more manageable.
[0009] One embodiment of a basic riveting tool comprises a tool housing, a riveting tool, and a drive device in the tool housing for actuating the riveting tool. For example, the riveting tool, in particular the riveting tool, is suitable for blind riveting. The term "blind riveting" is understood in particular to mean that the riveting process is carried out from one side of the material to be provided with a blind rivet using a rivet mandrel. Instead of a blind rivet, a blind rivet nut or a blind rivet screw can also be used.
[0010] The riveting tool preferably has a mouthpiece and a mandrel holder movable relative to the mouthpiece along or in the direction of an effective axis. For example, the mandrel holder comprises a chuck housing movable relative to the mouthpiece along or in the direction of the effective axis and at least one clamping element, in particular a clamping jaw, movable in the chuck housing along a clamping path.
[0011] The drive device can have a spindle gear, in particular a ball screw drive, with a threaded spindle and a spindle nut operatively connected thereto. In particular, the threaded spindle has a movement thread. In particular, the threaded spindle is operatively connected to the spindle nut via the movement thread. In particular, the threaded spindle is operatively connected to the mandrel holder and in particular is designed to be moved along the operative axis, in particular in order to drive the mandrel holder. In particular, the spindle nut is rotatably mounted. In particular, the spindle nut is driven or drivable, for example by an electric motor.
[0012] The basic riveting tool preferably has a support structure for axially supporting the spindle nut or for supporting the spindle nut in the direction of the effective axis. For example, the spindle nut is supported directly or indirectly, for example via an axial bearing, on the support structure. The support structure can be a component separate from the axial bearing or formed thereon. Alternatively, the support structure can be formed on a component of the axial bearing, such as a bearing ring, in particular molded onto it, or formed thereby. The support structure and / or the axial bearing is preferably arranged on the side of the spindle nut facing the riveting tool.
[0013] The drive device can alternatively comprise a preferably pneumatically and / or hydraulically driven cylinder-piston unit with a cylinder and a reciprocating piston accommodated therein for translational movement. In particular, the reciprocating piston is operatively connected to the mandrel holder and is particularly configured to be moved along the operative axis, in particular to drive the mandrel holder.
[0014] The term “cylinder” in the present disclosure refers in particular to a housing for the reciprocating piston, which can also be referred to as a piston housing. For example, the housing or piston housing has a hollow space in which the reciprocating piston is accommodated so as to be translationally movable in the direction of its piston axis. The housing or piston housing can be a tubular housing. In the case of this alternative drive device, a support structure may be provided for axially supporting the cylinder or for supporting the cylinder in the direction of the effective axis. For example, the cylinder is supported directly or indirectly on the support structure. The support structure is preferably arranged on the side of the cylinder facing the riveting tool. However, such a support structure can also be omitted, i.e. the basic riveting device can be present without such a support structure.
[0015] Preferably, the basic riveting device further comprises a tool housing in which the mandrel holder is accommodated so as to be axially movable relative to the effective axis. In particular, the tool housing is supported on the one hand on the mouthpiece and on the other hand, for example, via a flange, on the support structure. This is preferably the case if the drive device comprises the spindle gear described above.
[0016] The tool housing can also be axially supported on the one hand on the mouthpiece and on the other hand, for example via a flange on the optionally provided support structure and / or the cylinder. This is preferably the case when the drive device is provided with the cylinder-piston unit described above. For example, the tool housing and the mouthpiece are separate components. For example, the mouthpiece is attached to the tool housing. Alternatively, the mouthpiece can be molded onto the tool housing.
[0017] Preferably, the basic riveting tool further comprises a support structure for supporting the tool housing. Preferably, the basic riveting tool further comprises a holding structure, by means of which the tool housing is held, in particular loosely held, on the support structure. For example, the holding structure is separate from the tool housing, i.e., the holding structure and the tool housing are separate components.
[0018] An improved compactness is achieved by a design of the riveting tool in which the holding structure and the carrier structure are connected via a bayonet lock. It has been shown that the bayonet lock allows the riveting tool to be made axially shorter with respect to the effective axis than, for example, with a screw connection. Furthermore, the bayonet lock allows for faster changing of the tool housing compared to a screw connection. The bayonet lock is also easier to handle than a screw connection.
[0019] The term "bayonet closure" in the present disclosure is to be understood in particular as any type of mechanical connection between two connecting parts which is produced by plugging them together in the direction of a plug-in axis and then rotating the connecting parts relative to one another about the plug-in axis. To produce the mechanical connection, a plug-in and rotating movement of the connecting parts relative to one another is carried out. The connecting parts are preferably brought into a locking position relative to one another by the rotating movement, in which position they are locked, preferably in a form-fitting manner, against being pulled apart along the plug-in axis.
[0020] In one embodiment, the bayonet closure comprises a bayonet connection which is assigned to the holding structure, in particular is arranged or formed on the holding structure. Furthermore, the holding structure comprises a through-opening in a wall surface. The tool housing is received in the through-opening, for example with radial play, and in particular the wall surface, for example in the region around the through-opening, serves as an axial limitation for the flange of the tool housing. For example, the holding structure is a coupling element, in particular a coupling ring.
[0021] In this embodiment, the improved riveting tool can be designed such that the bayonet connection is provided at a radial distance from the through-opening. For example, the bayonet connection is provided at a radial distance and concentrically to the through-opening. Due to such a radial arrangement of the bayonet connection relative to the through-opening, the bayonet connection is located radially outwards to the tool housing. This is a further measure which promotes a compact design of the riveting tool in the axial direction with regard to the axis of action. The design in which the bayonet connection has a ring structure whose inner circumference surrounds the through-opening and in particular the tool housing at a radial distance is also aimed in this direction.
[0022] In a further embodiment, the bayonet connection comprises a plug-in receptacle, and the plug-in receptacle has a circumferential surface which runs at a radial distance around the through-opening. In this case, the improved riveting tool can be designed such that at least two radially inwardly projecting ring segments are provided on the circumferential surface, which are distributed over the circumference of the plug-in receptacle and serve to lock the bayonet closure. This represents a further measure which promotes a compact design of the riveting tool in the axial direction with respect to the effective axis. In particular, the at least two ring segments form gaps between them, via which gaps the plug-in receptacle is accessible in the axial direction.
[0023] For example, the plug-in receptacle has a base surface. To optimize axial compactness, it can be provided that the base surface coincides with the wall surface containing the through-opening and / or that the base surface and the wall surface lie in a common plane or are at least axially close to one another.
[0024] The improved riveting tool can be designed such that the plug-in receptacle is formed by an annular and / or rounded recess in the support structure. This avoids the need for a separate component for providing the plug-in receptacle, and the installation space required for this can be saved. Preferably, the base of the recess is dimensioned such that the insertion depth of the plug-in receptacle is limited.
[0025] In a further embodiment, the bayonet closure comprises a bayonet connection which is assigned to the support structure, in particular is arranged or formed on the support structure. In this case, the improved riveting device can be designed such that the support structure has an annular extension, on the outer circumference of which at least two radially outwardly projecting ring segments are provided, which are arranged distributed over the outer circumference and serve to lock the bayonet closure. This radial arrangement makes it possible to save installation space in the axial direction with respect to the effective axis. In particular, the extension is designed or can be used as a plug-in part for insertion into the plug-in receptacle described above.In particular, the at least two ring segments of the extension form gaps between them, which are dimensioned such that when the extension is inserted into the plug-in receptacle, the at least two ring segments on the plug-in receptacle fit into the gaps. Preferably, the gaps between the at least two ring segments of the plug-in receptacle are dimensioned in the same way, so that when the extension is inserted into the plug-in receptacle, the at least two ring segments of the extension fit into the gaps between the at least two ring segments of the plug-in receptacle.
[0026] In particular, the carrier structure is arranged on the support structure or formed by the support structure, in particular, it is molded onto it. This allows the ring segments to be made thinner in the axial direction relative to the effective axis, particularly if the support structure consists of or comprises a load-resistant material, such as metal. In this way, axial installation space can be saved.
[0027] In particular, a flange surface that interacts with the flange of the tool housing is formed on the inner circumference of the annular extension. For example, the carrier structure and the support structure are formed on a common component. In this embodiment, it is preferably provided that the carrier structure and the device housing are separate components.
[0028] In another embodiment, the bayonet closure comprises a bayonet connection, which is assigned to the device housing, in particular is arranged or formed on the device housing. By assigning the bayonet connection to the device housing, manufacturing costs can be saved, in particular if the device housing consists of or comprises a plastic material.
[0029] In this case, the improved riveting tool can be designed such that the tool housing has an annular extension, on the outer circumference of which at least two radially outwardly projecting ring segments are provided, which are distributed over the outer circumference and serve to lock the bayonet lock. For example, it can be provided that the inner circumference of the annular extension surrounds the carrier structure and / or the support structure and / or the tool housing and / or the flange with a radial distance or at least with radial play.
[0030] Alternatively, a flange surface that interacts with the flange of the tool housing can be provided on one end face of the annular extension. This configuration is suitable if the riveting tool has the cylinder-piston unit described above. In this case, the support structure can be arranged on the cylinder or formed by the cylinder.
[0031] A further embodiment consists in that the device housing has an at least partially tubular contour. In particular, the support structure is arranged on an end face of the tubular contour facing the mouthpiece. For example, the tubular contour preferably runs with its tube axis coaxial with the effective axis.
[0032] In this embodiment, the improved riveting tool can be designed such that the holding structure extends circumferentially around the outer circumference of the tool housing with respect to the effective axis and, in particular, covers one end face of the tubular contour and / or closes the interior of the tubular contour of the tool housing at the end face. This gives the holding structure an additional lid or covering function. To achieve an aesthetic appearance, the holding structure's outer circumference contour should be adapted to the tubular contour of the tool housing in the region of the facing end face.
[0033] The improved riveting tool can further be designed such that at least one light source is provided in the tool housing and that the holding structure is designed as a light guide at least in one area or has a light guide in order to allow light rays from the light source to pass through it in the direction of the mouthpiece. This means that the light source is housed in a protected manner and at the same time its function is retained, namely to illuminate the working area of the riveting tool. The working area includes, for example, the area around the front end of the tool housing, i.e. where the rivet is inserted. For example, viewed radially outwards, the light guide is arranged downstream of the bayonet closure and / or the support structure. This promotes light exiting the tool housing because the bayonet closure or the support structure does not require an opening for the light to pass through.
[0034] The light guide of the support structure can be an optical lens and / or perform a lens function, for example, by focusing or dispersing light rays from the light source. This makes it easy to achieve the desired illumination over a desired area. For example, the light source is an LED. In the present disclosure, an "LED" is understood to mean both a single LED and an LED unit with multiple LEDs, such as a COB LED, wherein the LED can be mounted or pre-mounted on a carrier board. It also includes an LED chip.
[0035] In order to have the holding structure in a desired rotational position relative to the support structure in an end position or closed position of the bayonet closure, a stop is provided. The stop can comprise or be formed from a material section or a formation on the holding structure and / or the support structure. Preferably, the region designed as a light guide or the region of the holding structure provided with the light guide is arranged such that in the end position or closed position of the bayonet closure, the light guide is at a predetermined location in order to achieve the desired light transmission.
[0036] For example, the support structure is ring-shaped and has a circumferential collar on its outer circumference, which engages with axial and / or radial play in a receptacle of the device housing. This prevents, or at least counteracts, a driving force or setting force exerted by the threaded spindle on the mandrel receptacle from acting via the support structure into the device housing. The device housing can thus be designed with a view to lower component stress, thereby saving costs and / or weight.
[0037] For example, the improved riveting device can be designed in such a way that the support structure is circular and has a groove or other elongated recess on the circumference, the longitudinal extent of which extends along the effective axis, wherein a material section or spring section of the device housing engages in the groove or recess in order to form an anti-twist device.
[0038] This facilitates simple and / or cost-effective production.
[0039] In a further embodiment, the riveting tool is designed as a hand-held riveting tool and comprises a handle which, for example, has a longitudinal extension transverse to the effective axis. For example, the handle is formed on the tool housing, in particular molded thereto or attached thereto. The handle allows the riveting tool to be held in the hand or guided manually. In particular, the handle enables the riveting tool to be manually applied to a location to be riveted.
[0040] According to one aspect, a blind rivet setting tool is proposed. The blind rivet setting tool comprises the riveting tool described above and has a rivet mandrel of a blind rivet to be set, which is received in its mandrel holder.
[0041] According to a further aspect, a blind rivet nut setting tool is proposed. The blind rivet nut setting tool comprises the riveting tool described above and has a threaded rivet mandrel accommodated in its mandrel holder for a blind rivet nut to be set.
[0042] According to a further aspect, a blind rivet screw setting tool is proposed. The blind rivet screw setting tool comprises the riveting tool described above and has a threaded rivet mandrel for a blind rivet screw to be set, which is accommodated in its mandrel holder.

[0057] Figure 1 shows the structure of an exemplary embodiment of a riveting tool 1, which is also referred to in specialist circles as a setting tool. The exemplary riveting tool 1 is suitable for attaching or setting rivets using the blind riveting method and is therefore designed for use with blind rivets.
[0058] The exemplary riveting device 1 comprises a riveting tool 10 and a drive device 30 for actuating the riveting tool 10. The riveting tool 10 is preferably assigned to a tool housing 4. The drive device 30 is preferably assigned to a device housing 5, in particular accommodated therein. The tool housing 4 is preferably a metal housing. The device housing 5 is preferably a plastic housing.
[0059] The exemplary riveting tool 1 can be a hand-held riveting tool. The hand-held riveting tool 1 has, for example, a gripping surface 2.1, which can be at least partially formed on the tool housing 5. For example, the hand-held riveting tool 1 has a handle part 2, which is at least partially formed by the tool housing 5. The gripping surface 2.1 or the handle part 2 enables the riveting tool 1 to be held in the hand when it is applied to a workpiece to set a rivet, in particular a blind rivet. The riveting process as such then takes place by actuating the riveting tool 10 via the drive device 30. The drive device 30 is preferably an electromechanical drive device. The electromechanical drive device 30 comprises, for example, an electric motor 31 with a rotatable output shaft 31. 1 and preferably a spindle gear 32 which can be driven by the electric motor 31.Preferably, the spindle gear 32 is configured to convert a rotary drive movement originating from the output shaft 31.1 into a translatory drive movement acting along an effective axis W for actuating the riveting tool 10. The spindle gear 32 may be a ball screw drive.
[0060] In the exemplary riveting device 1, for example, at least one, preferably two reduction stages 37, 37' are interposed between the electric motor 31 and the spindle gear 32. For example, the reduction stages 37, 37' are connected one after the other in the power flow. For example, the reduction stages 37, 37' use a common intermediate shaft 38. For example, at least one of the reduction stages 37, 37' is a spur gear stage, and the associated gear elements are spur gears.
[0061] To supply electrical energy to the drive device 30, a preferably replaceable electrical energy storage device, such as a rechargeable battery 3, can be provided, which is arranged, for example, in the region of an end of the handle part 2 facing away from the riveting tool 10. In this respect, the riveting tool 1 can be a battery-powered device.
[0062] The riveting tool 10 can comprise a mouthpiece 11 and a mandrel holder 12 movable relative to the mouthpiece 11 in the direction of the effective axis W. For example, the mandrel holder 12 has a chuck housing 13 and at least one, preferably several, clamping elements 14, 14', in particular clamping jaws, movable in the chuck housing 13 along a clamping path. Preferably, the mouthpiece 11 and / or the mandrel holder 12 and / or the chuck housing 13 and / or the clamping elements 14, 14' are a metal part.
[0063] The mouthpiece 11 serves, for example, to receive a rivet (not shown in Figure 1) to be set, in particular a blind rivet, and preferably has a through-hole 11.1 for inserting the rivet mandrel of the rivet therein. The mandrel receptacle 12 serves, for example, to fix the rivet mandrel so that a displacement-proof connection is created between the received rivet mandrel and the mandrel receptacle 12. This can be done, for example, via the chuck housing 13 with the clamping elements 14, 14' arranged movably therein, by means of which the rivet mandrel is fixed, in particular clamped, in the chuck housing 13.
[0064] The drive device 30 can actuate the riveting tool 10 in such a way that the mandrel holder 12 or the chuck housing 13 with the rivet mandrel fixed therein is moved away from the mouthpiece 11 in the direction of the effective axis W. This occurs, for example, in that the drive device 30 pulls the mandrel holder 12 or the chuck housing 13 away from the mouthpiece 11. This known mode of operation and the blind riveting that can be carried out with it are described in more detail in the document EP 0 116 954 A2, to which reference is hereby made for the purpose of completing and supplementing the present disclosure with the note that the document may assign a meaning to identical terms which differs from the present meaning.
[0065] Preferably, the mouthpiece 11 is fastened to the tool housing 4, for example, screwed thereto. Preferably, the mandrel receptacle 12, in particular the chuck housing 13, is accommodated in the tool housing 4 so as to be movable in the direction of the effective axis W. For example, the tool housing 4 has an elongated, in particular tubular, base body. In this respect, the tool housing 4 is also referred to in specialist circles as a setting sleeve. For example, the mouthpiece 11 is fastened to one end of the tool housing 4 and the opposite end faces the device housing 5.
[0066] The spindle gear 32 is preferably arranged in the device housing 5. The spindle gear 32 preferably comprises a threaded spindle 33 with a movement thread and a spindle nut 34 which engages or can be brought into engagement therewith. The threaded spindle 33 preferably has a front end 33.1 facing the mandrel holder 12, in particular the chuck housing 13, and an opposite rear end 33.2. The threaded spindle 33 and the spindle nut 34 are preferably arranged concentrically to one another with respect to a gear axis. The spindle axis S of the threaded spindle 33 preferably lies on the gear axis. The output shaft 31.1 of the electric motor 31 is preferably arranged axially parallel to the gear axis. The gear axis or the spindle axis S preferably lies on the effective axis W.
[0067] For example, the threaded spindle 33 and the spindle nut 34 are arranged in such a way that the spindle nut 34 is the gear element driven or drivable by the electric motor 31 and the threaded spindle 33 is used to carry out the translational drive movement in order to actuate the riveting tool 10. For example, the threaded spindle 33 is at its front end
[0068] 33 . 1 is connected directly or indirectly, for example via an intermediate piece, to the mandrel holder 12 or the chuck housing 13, in a displacement-proof manner. For example, the spindle nut 34 is furthermore rotatably mounted in the device housing 5 in the radial direction with respect to the gear axis or the effective axis W via at least one, preferably two radial bearings 35, 35 '.
[0069] In the exemplary riveting tool 1, for example, a torque arm 41 is provided to secure the threaded spindle 33 against rotation relative to the tool housing 5. For example, the torque arm 41 is arranged on the threaded spindle 33, in particular fastened thereto or connected thereto in a rotationally fixed manner. For example, the torque arm 41 is supported, preferably via at least one sliding body or rolling body, against an abutment 43 in order to form the rotation lock for the threaded spindle 33. The abutment 43 itself can be arranged in a rotationally fixed or rotationally fixed manner relative to the tool housing 5. For example, the abutment 43 has at least one guide track on which the torque arm 41 is guided while maintaining the rotation lock when the threaded spindle 33 executes a translational movement along the effective axis W.
[0070] In the exemplary riveting tool 1, for example, a spring element 15 is provided, which acts with a force, for example via a pressing part 16, into the mandrel receptacle 12. For example, the spring element 15 is arranged in the threaded spindle 33. For example, the threaded spindle 33 and / or the torque support 41 serve as a counterholder for the spring element 15.
[0071] The force of the spring element 15 can be used as a preload force, by which the fixation of the rivet mandrel in the mandrel holder 12 is effected or at least supported. For example, the spring element 15 is provided in order to apply a spring force to the clamping elements 14, 14' into the chuck housing 13. As a result, the clamping elements 14, 14' are pressed into the clamping position against a rivet mandrel, for example a blind rivet, which is inserted into the chuck housing 13 via the through-hole 11. 1 of the mouthpiece 11. For example, the spring element 15 is a compression spring.
[0072] Preferably, the threaded spindle 33 is designed as a hollow spindle with a passage 40 extending in the direction of its longitudinal extent. The passage 40 makes it possible to remove a remainder of a rivet mandrel remaining from a riveting process from the riveting tool 10. For example, in this case, the pressing part 16 arranged at the front end 33.1 of the threaded spindle 33 is received in the passage 40 and is itself designed as a hollow body with a passage 16.1.
[0073] For example, the passage 40 opens at the rear end 33.2 of the threaded spindle 33 into a tubular element 50, which in turn opens into a collecting container 60. For example, a mandrel disposal path is realized in this way via the threaded spindle 33, wherein the collecting container 60 can serve as a collector for mandrel residues. Preferably, the collecting container 60 is arranged fixedly with respect to the device housing 5, in particular detachably arranged, for example fastened to the device housing 5, in particular detachably fastened.
[0074] For example, the torque support 41 is also designed as a hollow body with a passage, which is, for example, a component of the mandrel disposal path to the collecting container 60. For example, the torque support 41 engages in the passage 40 of the threaded spindle 33, and the tubular element 50 engages in the passage of the torque support 41.
[0075] In the exemplary riveting tool 1, for example, a support structure 39 is provided on which, axially with respect to the effective axis W, on the one hand the tool housing 4 and, on the other hand, an axial bearing 36, preferably designed as a thrust bearing, are supported, which in turn is axially supported on the spindle nut 34. The mouthpiece 11 is therefore mounted via the tool housing 4 and the support structure 39 on the axial bearing 36, which in turn is supported on the spindle nut 34. In this way, a load path for the setting force occurring during a riveting process is formed, bypassing or largely bypassing the tool housing 5. In the exemplary riveting tool 1, for example, a support structure 7 is provided which carries the tool housing 4.A connection between the tool housing 4 and the support structure 7 is realized in the present case, for example, in that the tool housing 4 is held, preferably loosely, on the support structure 7 via a holding structure 6. To better illustrate this, Figure 2 shows the exemplary riveting device 1 in the region of the connection of the tool housing 4 to the support structure 7 in an enlarged section of Figure 1. The support structure 7 itself is shown in a perspective view in Figure 3.
[0076] The carrier structure 7 is, for example, ring-shaped. The support structure 39 can have a circumferential collar 39.3 on its outer circumference, which, for example, engages with axial and / or radial play in a receptacle 5.3 of the device housing 5. As can be seen in particular from Figures 2 and 3, the carrier structure 7 can be arranged on the support structure 39, in particular formed, for example, integrally formed.
[0077] In particular, it can be provided that the carrier structure 7 and the support structure 39 are formed on a common component. In this respect, the annular carrier structure 7 or support structure 39 can have a flange surface 39.2 on its inner circumference, which corresponds to a flange surface 4.2 of a flange 4.1 of the tool housing 4. This is to be able to form the load path described above. For this purpose, the flange surfaces 39.2, 4.2 can be designed as a circumferential inclined surface. For example, the inclined surface widens radially in the direction of the mouthpiece 11.
[0078] The support structure 39 can be designed as a bearing housing on its end face facing the axial bearing 36 and, for example, have a recess 39 . 5 into which the axial bearing 36 is at least partially received or inserted. For example, the axial bearing 36 is an axial roller bearing. In principle, the axial bearing 36 can also be a needle bearing.
[0079] The support structure 39 can be circular. For example, the support structure 39 has a groove 39.4 on the outer circumference, the longitudinal extent of which extends in the direction of the effective axis W, and a spring section (not shown in the figures) of the device housing 5 engages in the groove 39.4 in order to form an anti-twist device. The support structure 39 is preferably designed to be resistant to deformation, in particular to bending. For example, the support structure 39 is a metal part.
[0080] As already explained above, the tool housing 4 is held on the support structure 39 via the holding structure 6. For illustration purposes, Figure 4 shows the exemplary holding structure 6 in a perspective view.
[0081] The holding structure 6 is preferably a separate component. For example, the holding structure 6 has a through-opening 6.1 in a wall surface 6.2. For example, the tool housing 4 is received in the through-opening 6.1 or the holding structure 6 is pushed onto the tool housing 4. In this respect, the holding structure 6 is, for example, a coupling element. For example, the wall surface 6.2 in the area around the through-opening 6.1 serves as an axial boundary for the flange 4.1 of the tool housing 4.
[0082] The radial dimension of the holding structure 6 is, for example, adapted to the radial dimension of the device housing 5. For example, the device housing 5 has an at least partially tubular contour 5.2 in the region around the effective axis W. For example, the tubular contour 5.2 lies coaxially to the effective axis W. For example, the holding structure 6 is arranged on an end face 5.4 of the tubular contour 5.2 facing the mouthpiece 11. For example, the holding structure 6 runs around the outer circumference of the tool housing 4 with respect to the effective axis W and closes off the interior of the tubular contour 5.2 of the device housing 5 at the end face.
[0083] In the exemplary riveting tool 1, a fastening of the holding structure 6 to the carrier structure 7 is provided, for example, via a bayonet lock 70. The bayonet lock 70, in addition to the proposed design of the carrier structure 7 or support structure 39 and the holding structure 6, facilitates fastening of the tool housing 4 to the carrier structure 7 in an axially compact manner with respect to the effective axis W. For example, the bayonet lock 70 comprises a bayonet connection 71, which is assigned to the holding structure 6, in particular is arranged thereon, for example is formed thereon. For example, the bayonet connection 71 is arranged at a radial distance from the through-opening 6.1. For example, the bayonet connection 71 has a ring structure, and the inner circumference of the ring structure surrounds the through-opening 6.1 at a radial distance. For example, the ring structure is concentric with the through-opening 6.1 with respect to its central axis M2.
[0084] The bayonet connection 71 comprises, for example, a plug-in receptacle 72 in an annular recess 6.3 in the support structure 6 with a circumferential surface 72.1 and a base surface 72.2. The circumferential surface 72.1 extends, for example, at a radial distance around the through-opening 6.1. The bayonet connection 71 further comprises, for example, at least two radially inwardly projecting ring segments 73, 73', which preferably lie on the circumferential surface 72.1, are preferably distributed over the circumference of the plug-in receptacle 72, and serve to lock the bayonet closure 70.
[0085] The bayonet lock 70 has a further bayonet connection 74, which is provided on the support structure 7. For example, the further bayonet connection 74 is arranged, in particular formed, on an annular extension 39.1 of the support structure 7 or support structure 39. For example, the annular extension 39.1 is smaller in diameter than the outer contour of the support structure 39, so that a circumferential shoulder 39.6 is formed.
[0086] For example, the annular extension 39.1 is designed to be inserted as a plug-in part into the plug-in receptacle 72 of the holding structure 6. For example, the flange surface 39.2, which interacts with the flange 4.1 of the tool housing 4, is formed on the inner circumference of the extension 39.1. For example, at least two radially outwardly projecting ring segments 75, 75' are provided on the outer circumference of the extension 39.1, which are distributed over the outer circumference and serve to lock the bayonet lock 70.
[0087] Preferably, the at least two ring segments 73, 73' of the bayonet connection 71 form gaps between them, through which the plug-in receptacle 72 is accessible in the axial direction. Preferably, the at least two ring segments 75, 75' of the annular extension 39.1 also form gaps between them. The gaps are preferably dimensioned such that when the extension 39.1 is inserted into the plug-in receptacle 72, the at least two ring segments 73, 73' on the plug-in receptacle 72 fit into the gaps between the at least two ring segments 75, 75' of the extension 39.1. Preferably, the gaps between the at least two ring segments 73, 73' on the plug-in receptacle 72 are dimensioned in such a way that when the extension 39.1 is inserted into the plug-in receptacle 72, the at least two ring segments 75, 75' of the extension 39.1 fit into the gaps between the at least two ring segments 73, 73' of the plug-in receptacle 72.
[0088] The bayonet connection 71 and the further bayonet connection 74 enable a mechanical connection or fastening of the holding structure 6 to the support structure 7 by a plug-and-turn movement. In a first step, the plug-in receptacle 72 of the holding structure 6 is pushed onto the tubular extension 39.1, i.e. the tubular extension 39.1 is inserted into the plug-in receptacle 72. The achieved plug-in connection between the holding structure 6 and the support structure 7 while receiving the tool housing 4 is shown in a simplified sectional view in Figure 5. In this state, the holding structure 6 and the support structure 7 can be detached from one another in the axial direction. The central axis M2 of the through-opening 6.1 of the holding structure 6 and the central axis M1 of the support structure 7 are preferably coaxial to one another.
[0089] In a second step, the holding structure 6 is rotated relative to the support structure 7 about the central axis M1 or M2, causing the ring segments 73, 73' on the holding structure 6 to engage with the ring segments 75, 75' on the support structure 7, forming a locking mechanism of the bayonet catch 70, which positively prevents the holding structure 6 from being released from the support structure 7 in the axial direction. This state is shown in a simplified sectional view in Figure 6.
[0090] Preferably, a stop or rotation stop (not shown in the figures) is provided, by which the rotational movement of the holding structure 6 relative to the support structure 7 is limited when the bayonet lock 70 is locked. This allows the holding structure 6 to be brought into a desired rotational position in the locking position of the bayonet lock 70. The stop prevents over-rotation, thus preventing the resulting release of the lock.
[0091] However, another effect can also be utilized through the stop. For example, a light source 80, such as an LED, is arranged in the device housing 5. A ring with several light sources 80, 80', in particular LEDs, distributed around the circumference can also be provided, which ring runs around the effective axis W. For example, in this case, the holding structure 6 has one or more light guides 81, 81' in order to allow light rays from the light source 80 or 80' to pass through in the direction of the mouthpiece 11. For example, viewed radially outwards, the light guide 81 or 81' is arranged downstream of the banquet closure 70 or the support structure 39.
[0092] The stop ensures that in the locking position of the bayonet lock 70 the light guide 81 or 81' is in the specified position, that a desired radiation of the light rays generated by the associated light source 80 or 80' occurs, in particular in the desired direction.
[0093] Figure 7 shows an exemplary further embodiment of a riveting tool 1'. Figure 7 shows the further exemplary riveting tool 1' in an exemplary section, which is shown in a comparable manner in Figure 2 for the riveting tool 1. Components of the further exemplary riveting tool 1' that are structurally identical or functionally identical to components of the exemplary riveting tool 1 of Figures 1 and 2 are provided with the same reference numerals; in this respect, reference is made to the description of the exemplary riveting tool 1 of Figures 1 and 2.
[0094] The further exemplary riveting tool 1' differs from the exemplary riveting tool 1 of Figures 1 and 2 in that a tool housing 5' is provided, which accommodates the drive device 30 and is used for the bayonet connection 70. In the further exemplary riveting tool 1', for example, the above-described bayonet connection 74 is assigned to the tool housing 5', for example, the tubular contour 5.2 of the tool housing 5', in particular arranged thereon, for example, molded thereon. In the further exemplary riveting tool 1', for example, a support structure 39' is provided, which can correspond to the support structure 39 of the exemplary riveting tool 1, but for example without the ring segments 75, 75' of the bayonet connection 74.
[0095] In contrast, in the further exemplary riveting tool 1', the tool housing 5' has an annular extension 5.1', on the outer circumference of which the at least two radially outwardly projecting ring segments 75, 75' of the bayonet connection 74 are arranged or formed. The tool housing 5' can otherwise be structurally identical to the tool housing 5 of the exemplary riveting tool 1 of Figures 1 and 2.
[0096] Figure 8 shows, by way of example, the device housing 5' in the region of the annular extension 5.1'. For example, the annular extension 5.1' is formed on the device housing 5', for example, integrally formed. For example, the annular extension 5.1' is located on one end face 5.4 of the tubular contour 5.2 of the device housing 5'. For example, the inner circumference of the annular extension 5.1' surrounds the support structure 39' with radial clearance (Figure 7).
[0097] Figure 9 shows an exemplary embodiment of a riveting tool 1 '' . Figure 9 shows the exemplary riveting tool 1 '' in a simplified representation as a partial section. Components of the exemplary riveting tool 1 '' that are structurally identical or functionally identical to components of the exemplary riveting tool 1 of Figures 1 and 2 are provided with the same reference numerals; in this respect, reference is made to the description of the exemplary riveting tool 1 of Figures 1 and 2.
[0098] The further exemplary riveting device 1 '' differs from the exemplary riveting device 1 in Figure 1, among other things, in that the drive device 30 comprises a cylinder-piston unit 90, which serves to actuate the riveting tool 10. The cylinder-piston unit 90 preferably has a cylinder 91 and a reciprocating piston 92. For example, the cylinder 91 forms a device housing 5 '' accommodating the drive device 30 or is a component thereof. The cylinder 91 preferably has a piston chamber 93 in which the reciprocating piston 92 is accommodated for translational movement. The reciprocating piston 92 is preferably operatively connected to the mandrel holder 12. For this purpose, a piston extension 94 can be arranged, in particular formed, on the lifting piston 92, which is connected, in particular screwed, to the mandrel holder 12, in particular the chuck housing 13, at an end or end region facing the riveting tool 10.For example, the piston extension 94 is tubular. For example, the piston axis K of the reciprocating piston 92 lies on the effective axis W. For example, the reciprocating piston 92 is configured to be moved along the effective axis W.
[0099] The cylinder-piston unit 90 allows the drive device 30 to be operated pneumatically and / or hydraulically. For example, at least one supply channel 96 is provided for this purpose. For example, the supply channel 96 opens into a fluid chamber 95, via which a media pressure can be exerted on the reciprocating piston 92. The further exemplary riveting tool 1'' is, for example, a compressed air-operated riveting tool. Such a compressed air-operated riveting tool is known per se and is described in more detail in the document EP 1 132 160 A1, to which reference is hereby made for the purpose of completing and supplementing the present disclosure, with the note that the document may assign a meaning to identical terms that differs from the present meaning.
[0100] In the further exemplary riveting tool 1 ' ', the mandrel holder 12 is accommodated in an axially movable manner in a tool housing 4 ' ', which is supported on the one hand on the mouthpiece 11 and on the other hand axially on the cylinder 91 via a flange 4.1' '. For example, the flange 4.1' ' has a flange surface 4.2' ', which corresponds to a counter-flange surface 97.1', which is assigned to the cylinder 91. For example, the counter-flange surface 97.1' is formed on the cylinder 91. For example, the flange surface 4.2 ' ' of the tool housing 4 ' ' is arranged transversely, in particular orthogonally, to the effective axis W. For example, the flange surface 4.2' ' of the tool housing 4 ' ' rotates around the effective axis W.
[0101] In the further exemplary riveting device 1 ' ', for example, a support structure 7 ' ' is provided which carries the tool housing 4 ' '. A connection between the tool housing 4 ' ' and the support structure 7 ' ' is realized in the present case, for example, in that the tool housing 4 ' ' is inserted over a longitudinal section 4.3 ' ' into a recess or a passage in the device housing 5 ' ' and / or the cylinder 91. In this respect, the longitudinal section 4.3 ' ' serves as an insertion section. The outer circumference of the insertion section and the inner circumference of the recess or passage preferably correspond accordingly, in particular with play. In this way, support transverse to the effective direction W is achieved.
[0102] For example, the longitudinal section 4.3'' extends from a free end of the tool housing 10, which is opposite the mouthpiece 11, to the flange 4.1''. The flange 4.1'' is provided, for example, as a circumferential collar on the outer circumference of the tool housing 4'', in particular arranged or molded thereon. The flange 4.1'' thus limits the insertion depth into the device housing 5'' or the cylinder 91.
[0103] In the further exemplary riveting tool 1 '', for example, a holding structure 6'' is provided to prevent the tool housing 4'' from being pulled out of the recess or passage of the tool housing 5 '' or the cylinder 91. The holding structure 6'' is preferably a separate component. For example, the holding structure 6 '' is designed corresponding to the holding structure 6 of the exemplary riveting tool 1 according to Figure 1. In this respect, reference is made to the above description of the holding structure 6.

The bayonet lock can be the bayonet lock 70 with the bayonet connections 71 and 74, as used in the riveting tool 1 of Figure 1. Reference is made to the above description, particularly to Figures 3 to 6.
[0105] In the further exemplary riveting tool 1' ', for example, the bayonet connection 71 is assigned to the holding structure 6' ', in particular arranged thereon, for example formed thereon. The further bayonet connection 74 is provided, for example, on the support structure 7' ', in particular the device housing 5' ' or the cylinder 91. For example, the further bayonet connection 74 is arranged, in particular formed, on an annular extension 99 of the support structure 7' '.

The cylinder-piston unit 90 comprises a cylinder 91' and a reciprocating piston 92' accommodated therein for translational movement. The reciprocating piston 92' is operatively connected to the mandrel holder 12. The cylinder 91' is supported with one axial end against the support structure 39, which in this case serves as an axial support for the cylinder 91'. In the riveting tool 1.1, as in the riveting tool 1, the support structure 39 and the carrier structure 7 are formed on the same component.

For example, a counterflange 97 for the flange 4.1 of the tool housing 4 is formed on the cylinder 91.1'. For example, the counterflange 97 has a counterflange surface 97.1, which corresponds to the flange surface 4.2 of the flange 4.1 of the tool housing 4. For example, in this case, a collar 98 of the cylinder 91.1' assumes the function of the circumferential collar 39.3 of the support structure 39, which is described above for the riveting tool 1.1 of Figure 10 or for the riveting tool 1 of Figure 1.

In the blind rivet nut setting tool 200, a threaded rivet mandrel 220 for a blind rivet nut 210 is received in the mandrel holder 12. Figure 10 shows the blind rivet nut 210 in the state before riveting, in which the rivet body 230 of the blind rivet nut 210 is still in its initial state.For example, in the exemplary blind rivet nut setting tool 200, the pressing part 16 is inserted into a receptacle of the threaded rivet mandrel 220 and forms a positive, rotationally fixed connection with the threaded rivet mandrel 220 via the receptacle. For example, the force of the spring element 15 of the riveting tool 1 (Figure 1), which acts axially on the pressing part 16, holds the pressing part 16 in the receptacle of the threaded rivet mandrel 220.
[0115] Figure 16 shows an example of a possible embodiment of a blind rivet screw setting tool 300.
