DETAILED DESCRIPTION

[0036] FIG. 1 shows the construction of an exemplary embodiment of a riveting device 1 which is also referred to as a setting device by experts. The exemplary riveting device 1 is suitable for applying rivets according to the blind riveting method, and in this regard is designed for using blind rivets.

[0037] The exemplary riveting device 1 comprises a riveting tool 10 and a drive device 30 for actuating the riveting tool 10. Preferably, the riveting tool 10 is received in a tool housing 12. Preferably, the drive device 30 is received in a device housing 50. Preferably, the tool housing 12 is a metal housing. Preferably, the device housing 50 is a plastic housing.

[0038] Preferably, the drive device 30 is an electromechanical drive device. The electromechanical drive device 30 comprises for example an electric motor 31 having 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 set up to convert a rotational drive movement coming from the output shaft 31.1 into a translational drive movement which acts along an operative axis W to actuate the riveting tool 10. The spindle gear 32 can be a ball screw drive.

[0039] FIG. 2 shows the exemplary riveting device 1 in the region of the riveting tool 10 and of the spindle gear 32 in an enlarged section of FIG. 1. As can be seen in particular, the riveting tool 10 can comprise a mouthpiece 11, a mandrel holder 13, which can be moved against the mouthpiece 11 in the direction of an operative axis W. For example, the mandrel holder 13 has a chuck housing 13.1 and at least one, preferably more clamping elements 14, 14, in particular clamping jaws, which can be moved in the chuck housing 13.1 along a clamping path. Preferably, the mouthpiece 11 and/or the mandrel holder 13 and/or the chuck housing 13.1 and/or the clamping elements 14, 14 are a metal part.

[0040] The mouthpiece 11 is used, for example, to receive a blind rivet (not shown in FIGS. 1 and 2) to be set and preferably has a through hole 11.1 in order to introduce the rivet mandrel of the blind rivet therein. The chuck housing 13 having the clamping elements 14, 14 arranged moveably therein serves, for example, to fix the rivet mandrel in the chuck housing 13, so that a non-displaceable connection between the received rivet mandrel and the chuck housing 13 is created.

[0041] The riveting tool 10 can be actuated by the drive device 30 so that the mandrel holder 13 or the chuck housing 13.1 with the rivet mandrel fixed therein is moved away from the mouthpiece 11 in the direction of the operative axis W. This happens, for example, by the drive device 30 pulling the mandrel holder 13 or the chuck housing 13.1 away from the mouthpiece 11. This mode of operation, which is known per se, and the blind riveting which can be carried out with it is described in more detail in the publication 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 publication may attach a meaning to identically worded terms which differs from the present meaning.

[0042] Preferably, the mouthpiece 11 is fixed to the tool housing 12, for example screwed to it. Preferably, the mandrel holder 13 or the chuck housing 13.1 is received in the tool housing 12 so as to be movable in the direction of the operative axis W. For example, the tool housing 12 is tubular. For example, the mouthpiece 11 is fixed on one end of the tool housing 12 and the opposite end faces towards the device housing 50.

[0043] Preferably, the spindle gear 32 is arranged in the device housing 50. Preferably, the spindle gear 32 comprises a threaded spindle 32.1 and a spindle nut 32.2 that is or can be engaged with the latter. Preferably, the threaded spindle 32.1 and the spindle nut 32.2 are arranged concentrically to each other with regard to a transmission axis. Preferably, the output shaft 31.1 of the electric motor 31 is arranged axially parallel to the transmission axis. Preferably, the transmission axis is on the operative axis W.

[0044] For example, the threaded spindle 32.1 and the spindle nut 32.2 are set up in such a way that the spindle nut 32.2 is the gear element that is or can be driven by the electric motor 31 and the threaded spindle 32.1 is used for performing the translational drive movement in order to actuate the riveting tool 10. For example, the spindle nut 32.2 is mounted rotatably in the device housing 50 and the threaded spindle 32.1 is secured against rotation relative to the device housing 50.

[0045] For example, the threaded spindle 32.1 is also operatively connected to the mandrel holder 13 or the chuck housing 13.1. This operative connection can be realised in that the threaded spindle 32.1 is directly connected with one end or end section to the mandrel holder 13 or the chuck housing 13.1. For example, the threaded spindle 32.1 and the mandrel holder 13 or the chuck housing 13.1 are screwed together.

[0046] Preferably, the threaded spindle 32.1 is formed as a hollow spindle with a through hole extending in the direction of its longitudinal extension. The through hole makes it possible to remove from the riveting tool 10 any rivet mandrel remaining from a riveting process, for example via a tubular element 4, and to supply it to a collection container 5. Preferably, the collection container 5 is arranged fixed integral with the housing relative to the device housing 50, in particular arranged releasably.

[0047] In the exemplary riveting device 1, the device housing 50 is used for radially mounting the spindle gear 32. FIGS. 1 and 2 show a possible embodiment as an example. The radial mounting of the spindle gear 32 takes place directly in the device housing 50. This can be realised in that the spindle gear 32 is radially mounted via a radial bearing 33 in a bearing housing 34 and the bearing housing 34 is formed on the device housing 50, for example moulded onto it. Preferably, the bearing housing 34 is therefore formed by the device housing 50. Therefore, installation space can be reduced in the radial direction. Simultaneously, in this manner, components for the radial mounting can be reduced.

[0048] Preferably, the radial bearing 33 has a bend-resistant outer ring 33.1 (FIG. 2) which is held in the bearing housing 34. This enables a sufficiently durable radial mounting function, even if the bearing housing 34 as a component of the device housing 50 is a plastic housing. For example, the radial bearing 33 is a roller bearing, in particular a deep groove ball bearing. In order to further improve the compactness of the riveting device 1 in the radial direction in relation to the transmission axis or the operative axis W, the radial bearing 33 is a thin section bearing.

[0049] With the exemplary riveting device 1, the radial bearing 33 is assigned by way of example to the spindle nut 32.2, i.e. the spindle nut 32.2 is mounted by the radial bearing 33. Preferably, the radial bearing 33 is attached to the outer circumference of the spindle nut 32.2. Preferably, another radial bearing 33 is provided for radially mounting the spindle nut 32.2, which is arranged in relation to the transmission axis at an axial distance from the radial bearing 33. Preferably, a drive point is located between the radial bearing 33 and the other radial bearing 33, by which the electric motor 31 is operatively connected to the spindle nut 32.2.

[0050] Preferably, the device housing 50 is similarly used for radially mounting the spindle nut 32.2 via the other radial bearing 33. This can be realised in the same manner as with the radial bearing 33, in that the radial mounting takes place directly in the device housing 50 via the other radial bearing 33. For example, another bearing housing 34 is provided for receiving the other radial bearing 33 and this other bearing housing 34 is formed on the device housing 50, for example moulded thereon.

[0051] An axial mounting of the spindle gear 32 takes place preferably via a separate axial bearing 35 in order to be able to absorb an axial force of the spindle gear to a sufficient degree that acts during operation of the riveting device 1. In the exemplary riveting tool 1, for example, the spindle nut 32.2 is mounted axially with respect to the transmission axis or the operative axis W via the axial bearing 35 in a support ring 36, for example serving as a bearing housing, wherein the support ring 36 is supported on the mouthpiece 11 in the axial direction via the tool housing 12. The tool housing 12 itself is held on the support ring 36, in particular held loosely, via a retaining structure 51, such as for example a ring-shaped cover element.

[0052] For example, the support ring 36 has a circumferential axial end section 36.1 which serves to position the axial bearing 35 in the radial direction. Preferably, the support ring 36 is designed to be resistant to deformation and pressure. For example, the support ring 36 is a metal part. For example, the support ring 36 is a separate component. For example, the axial bearing 35 is an axial roller bearing. In principle, the axial bearing 35 can also be a needle bearing.

[0053] One of the radial bearings 33, 33 for the spindle gear 32, in particular the radial bearing 33, can also have an axial bearing function. The additional axial bearing function lends itself to receive a counterforce coming from a spring element 15. The spring element 15 can be provided in order to apply a spring force to the clamping elements 14, 14 in the direction of the chuck housing 13.1. Therefore, the clamping elements 14, 14 are pushed into a clamping position against a rivet mandrel of a blind rivet which has been introduced via the through hole 11.1 of the mouthpiece 11 into the chuck housing 13.1.

[0054] For example, the spring element 15 is supported on the one hand against a counter holder 17 that is fixed against displacement relative to the threaded spindle 32.1 and on the other hand it acts via a pressure part 16, such as a pressure sleeve, on at least one of the clamping elements 14, 14. For example, the threaded spindle 32.1 is designed as a hollow spindle and the pressure part 16 is received therein via one end so that it can be displaced relative to the threaded spindle 32.1 and the counter holder 17 is fastened, in particular screwed, to the threaded spindle 32.1 via the other end. For example, the spring element 15 is arranged in the threaded spindle 32.1 between the pressure part 16 and the counter holder 17. For example, the spring element 15 is a compression spring.

[0055] The axial bearing function of the one radial bearing 33 serves, preferably exclusively, to receive the relatively low counterforce from the spring element 15. The bearing housing 34 is also designed in a corresponding manner, for example. The bearing housing 34 has an axial contact surface 34.1 on one side only, for example, so that the radial bearing 33 is supported axially against the bearing housing 34 solely in the direction of the counterforce caused by the spring element 15. For example, the radial bearing 33 is arranged in the region of the rear axial end of the spindle nut 32.2. The end of the spindle nut 32.2 facing away from the riveting tool 10 can be seen below the rear axial end. The other radial bearing 33 is arranged for example in the region of the front axial end of the spindle nut 32.2.

[0056] FIG. 3 shows the exemplary riveting device 1 in the region of the drive device 30 in an enlarged section. As can be seen clearly, at least one reduction stage 37 can be interposed between the electric motor 31 and the spindle gear 32. For radially mounting the at least one reduction stage 37, the device housing 50 can similarly be used, for example in that the radial mounting takes place directly in the device housing 50 via a further radial bearing 39. For example, to receive the other radial bearing 39, a shaft bearing housing 40 which is formed on the device housing 50, for example moulded on, is provided.

[0057] With the exemplary riveting device 1, the at least one reduction stage 37 has, for example, an intermediate shaft 38. Preferably, the intermediate shaft 38 is radially mounted in the shaft bearing housing 40 via the above-described radial bearing 39. Preferably, another radial bearing 39 is provided as a second radial bearing for the intermediate shaft 38. Preferably, the second radial bearing 39 is received in a further shaft bearing housing 40, which is formed on the device housing 50, for example moulded thereon. For example, in addition to the one reduction stage 37, a further reduction stage 37 is interposed between the electric motor 31 and the spindle gear 32, wherein the reduction stages 37, 37 are connected in series in the power flow and utilise the intermediate shaft 38 as a common intermediate shaft.

[0058] Preferably, the one radial bearing 39 radially supports the intermediate shaft 38 between gear elements 37.1, 37.1 of the reduction stage 37, 37 mounted thereon. The gear elements 37.1, 37.1 are each engaged with associated gear elements 37.2, 37.2 of the reduction stages and 37, 37, by which a gear element 37.1 is assigned to the output shaft 31.1 of the electric motor 31 and another gear element 37.2 is assigned to the spindle nut 32.2, in particular they are arranged thereon in a rotationally fixed manner. For example, at least one of the reduction stages 37, 37 is a spur gear stage and the associated gear elements 37.1, 37.2 or 37.1, 37.2 are spur gear wheels.

[0059] The device housing 50 can also be used for the radial mounting of the electric motor 31, for example by providing the radial mounting via radial bearings 41, 41 directly in the device housing 50. For example, further shaft bearing housings 42, 42 are formed on the device housing 50, in particular moulded thereon. In this manner, mounting of the electric motor 31 can be realised.

[0060] FIG. 4 shows an exemplary embodiment of the device housing 50 for the riveting device 1. The device housing 50 can be made up of several parts and can, for example, comprise at least two housing shells 52, 52 placed on each other in a parting plane 53. For example, the housing shells 52, 52 are half shells. FIG. 5 shows an example of one of the housing shells 52, 52, in particular the housing shell 52 in a view of its interior or of the parting plane 53.

[0061] As can be clearly seen from this, material mouldings can be provided on wall sections of the housing shell 52, which form the bearing housings described above, for example the bearing housings 34 and 34 for the spindle gear 32 and/or the shaft bearing housings 40, 40 for the at least one reduction stage 37 and/or the shaft bearing housings 42, 42 for the electric motor 31. Preferably, a circumferential section of the corresponding bearing housing is formed on the respective housing shell 52 or 52.

[0062] The riveting device 1 can be a hand riveting device. The hand riveting device 1 has a gripping surface 2.1, for example, which can be formed at least partially on the device housing 50. For example, the hand riveting device 1 has a handle part 2 which is at least partially formed by the device housing 50. The riveting device 1 can be held in the hand by the gripping surface 2.1 or the handle part 2, when it is positioned on a workpiece for setting a blind rivet. The riveting process takes place then by actuating the riveting tool 10 via the drive device 30.

[0063] A preferably replaceable electrical energy storage device, such as an accumulator 3, can be provided for the electrical energy supply of the drive device 30, which energy storage device is arranged, for example, in the region of an end of the handle part 2 facing away from the riveting tool 10. Therefore, the riveting device 1 can be a cordless tool.

[0064] Instead of the riveting device 1 for a blind rivet described here as an example, the device housing 50 with its at least one bearing housing 34 or 34 or 40 or 40 or 42 or 42 formed on it can also be used on a riveting device for a blind rivet nut or on a riveting device for a blind rivet screw for the radial mounting of the spindle gear 32 and/or of the at least one reduction stage 37 or 37 and/or of the electric motor 31. A reduction of components and/or a reduction of the weight of the riveting device is achieved by such a device housing. Fundamentally, all components of the riveting device are mounted directly on the device housing, preferably excluding the above-described axial bearing for receiving axial forces of the spindle gear.

[0065] FIG. 6 shows an example of a possible embodiment of a blind rivet setting tool 100. The blind rivet setting tool 100 has the construction of the above-described exemplary riveting device 1, with only a section of the exemplary riveting device 1 being shown in the region of the riveting tool 10 in FIG. 6 for simplicity. In the blind rivet setting tool 100, a rivet mandrel 120 of a blind rivet 110 is inserted into the mouthpiece 11 and received in the mandrel holder 13, in particular the chuck housing 13.1, and fixed in the axial direction, for example by the at least one clamping element 14 or 14. FIG. 6 shows the blind rivet 110 in the state before riveting, in which the rivet body 130 of the blind rivet 110 is still in its initial state.

[0066] FIG. 7 shows an example of a possible embodiment of a blind rivet nut setting tool 200. The blind rivet nut setting tool 200 has the construction of the above-described exemplary riveting device 1, wherein the mandrel holder 13 and the pressure part 16 are modified with regard to a rivet mandrel for a blind rivet nut and the rivet mandrel is a threaded rivet mandrel. For example, the pressure part 16 has a function there with regard to threading the threaded rivet mandrel into the blind rivet nut. In FIG. 7, only a section of the riveting device 1 is shown in the region of the riveting tool 10 for simplicity. With the blind rivet nut setting tool 200, a threaded rivet mandrel 220 for a blind rivet nut 210 is received in the mandrel holder 13. FIG. 7 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.
