Description

[0001] Device for setting a setting element and method for exchanging a tool on such a device

[0002] The application relates to a device for installing a setting element. Setting elements can be designed, for example, as connecting elements, such as screws, blind rivet nuts, or blind rivet bolts. However, setting elements can also comprise other elements that are inserted into components, for example, to seal holes, as is the case with sealing plugs. An example of such a sealing plug is the KL-Plug® from B&M.

[0003] In order to process different setting elements with a single fixture, it is usually necessary to convert the fixture. This usually requires replacing the tool, such as a mandrel. Furthermore, the tool must be replaced when it is worn. Replacing the tool with conventional fixtures is relatively complex and time-consuming.

[0004] It is an object of the present invention to provide a device and a method which enable the tool to be replaced more quickly and with less personnel effort.

[0005] The object is achieved by the subject matter of the independent claims. The dependent claims define embodiments of the invention.

[0006] The problem is solved, among other things, by a device for setting a setting element, comprising: a holder for a tool, a rotary drive with a drive shaft for rotationally driving the tool, and a clutch for selectively coupling the tool to the drive shaft or decouple the tool from the drive shaft. The clutch is designed to be actuated, i.e., engaged and / or disengaged, automatically by the device or by an external clutch actuating element. This makes it possible to automate the coupling and decoupling of the tool to the drive shaft and thus to carry out a tool change more quickly and with less personnel effort.

[0007] The device is preferably designed for setting a blind rivet nut, a blind rivet stud, or a sealing plug. For this purpose, the tool can have a threaded portion designed to engage with a threaded portion of the blind rivet nut, the blind rivet stud, or the sealing plug. However, the tool can also generally have a threaded portion designed to engage with a threaded portion of the setting element during a setting process.

[0008] Advantageous embodiments of the invention can be found in the dependent claims, the description and the drawing.

[0009] According to one embodiment, the clutch can be designed to rotationally couple the tool to the drive shaft when engaged and to release a rotational movement between the tool and the drive shaft when disengaged, for example to enable the tool to be unscrewed from the drive shaft. Alternatively or additionally, the clutch can be designed to block a translational movement between the tool and the drive shaft when engaged and to release it when disengaged. For example, the clutch can be designed to selectively block or release a radial movement of the tool relative to the drive shaft. This allows the tool to be removed laterally from the drive shaft when the clutch is disengaged. According to one embodiment, the device comprises a linear drive.The linear drive is preferably designed to move the drive shaft and / or the tool in at least one axial direction. If the device is a device for setting a blind rivet nut, a blind rivet stud, a sealing plug, or the like, the linear drive can be designed to deform the setting element by displacing one region of the setting element relative to another region of the setting element, as is usual with a blind rivet element, and thus plastically deforming the setting element.

[0010] According to a particularly cost-effective and compact embodiment, the linear drive can be designed to engage and / or disengage the clutch. The linear drive preferably comprises an electric motor. Alternatively, the device can comprise a pneumatic actuator, in particular provided separately from the linear drive, by means of which the clutch can be engaged and / or disengaged. According to another alternative, an external clutch actuating element can be provided, for example on a tool exchange unit or a tool change station, which is designed to engage and / or disengage the clutch. In this case, the clutch is thus not automatically engaged and / or disengaged by the device, but by an external clutch actuating element.In order for the clutch to be engageable and / or disengageable by the external clutch actuating element, the device can be brought into a specific position relative to the clutch actuating element, preferably by a robot arm. Alternatively or additionally, the clutch actuating element can be brought into a specific position relative to the device, preferably by a robot arm. In this position, the clutch actuating element can then interact with the clutch such that the clutch can be engaged and / or disengaged by the clutch actuating element. According to one embodiment, the linear drive is designed to move the tool and / or the drive shaft in a first direction in order to deform the setting element and to move the tool and / or the drive shaft in a second direction opposite to the first direction in order to disengage the clutch.The linear drive thus fulfills two functions: First, it deforms the setting element, and second, it disengages the clutch. The linear drive can also have a third function, namely, to engage the clutch. To engage the clutch, the linear drive can be designed to move the tool and / or the drive shaft in the first direction.

[0011] The linear drive preferably comprises a planetary roller screw drive. The linear drive can comprise a servo motor configured to impart a linear movement to the drive shaft and / or the tool via the planetary roller screw drive.

[0012] According to one embodiment, the rotary drive is designed to drive the drive shaft and / or the tool sequentially in two opposite directions of rotation. This makes it possible, for example, if the tool and the drive shaft can be coupled to one another via a thread, to automatically decouple the tool from the drive shaft and couple it to the drive shaft. Furthermore, if the setting element can be coupled to the tool via a thread, it is possible to automatically spin the setting element onto the tool, i.e., screw it on, and to automatically release the tool from the setting element after setting.

[0013] According to an advantageous embodiment, the clutch is designed to selectively couple the tool rotationally to the drive shaft or to decouple the tool rotationally from the drive shaft. Preferably, the clutch can be designed to block relative rotational movement between the tool and the drive shaft in the engaged state and to allow relative rotational movement between the tool and the drive shaft in the disengaged state. If the tool can be removed from the drive shaft by a rotational movement relative to the drive shaft, such a clutch can ensure in a simple and reliable manner that the tool can only be removed from the drive shaft when the clutch is disengaged.

[0014] According to one embodiment, the receptacle has a thread in order to screw the tool into the receptacle or onto the receptacle at the front. The receptacle is preferably part of the drive shaft. In this case, the drive shaft and the tool can have corresponding threads. The corresponding threads are preferably designed to screw the tool into the drive shaft or onto the drive shaft at the front. Alternatively, it would be possible, for example, for the tool to be inserted laterally into the drive shaft. For this purpose, the tool can have, for example, a head, i.e. a section with a diameter that is wider than the rest of the tool, and the drive shaft can have a corresponding shaft shoulder in order to enable axial fixing of the tool in the drive shaft.

[0015] According to one embodiment, the device can comprise a support element, in particular a pressure sleeve. The support element can have a contact surface with which a contact surface of the setting element can be brought into contact during the setting process in order to limit a movement of a section of the setting element in the axial direction. Preferably, the linear drive is designed to bring the contact surface of the setting element into contact with the contact surface of the support element during the setting process. The tool is advantageously movable in the axial direction relative to the contact surface of the support element in order to initially bring the contact surface of the setting element into contact with the contact surface of the support element during the setting process. The tool is preferably subsequently movable further in the axial direction in order to effect plastic deformation of the setting element.

[0016] According to one embodiment, the coupling comprises a coupling element that is guided axially movably in the drive shaft. The coupling element can be rotationally coupled to the drive shaft. For this purpose, the coupling element can have a non-circular circumference, for example, a hexagonal outer circumference, and the drive shaft can have a corresponding non-circular circumference, for example, a hexagonal inner circumference.

[0017] According to one embodiment, a movement-limiting device, in particular a stop, is provided, which is designed to limit the axial movement of the coupling element during an axial movement of the drive shaft such that further movement of the drive shaft generates a relative movement between the coupling element and the drive shaft. This allows for a simple decoupling between the coupling element and the drive shaft. The stop can preferably comprise an annular stop surface. This allows for a more reliable relative movement between the coupling element and the drive shaft.

[0018] According to one embodiment, the coupling element is coupled to the drive shaft via a spring element. The spring element is preferably designed to apply a force to the coupling element in the direction of the tool when the clutch is engaged. The spring element preferably serves to create a secure connection between the drive shaft and the coupling element when the clutch is engaged.

[0019] According to one embodiment, the coupling element has, at least in sections, a non-circular circumferential shape, in particular an outer circumferential shape. The non-circular circumferential shape can be designed to be plugged onto a non-circular circumferential shape, in particular an inner circumferential shape, of the tool. The coupling element and the tool are preferably rotationally coupled to one another when plugged onto one another. In other words, the coupling element can have, at least in sections, a non-circular circumferential shape, in particular an outer circumferential shape, and the tool can have, at least in sections, a corresponding non-circular circumferential shape, in particular an inner circumferential shape, so that the coupling element and the tool can be plugged onto one another and, in the plugged-together state, are rotationally fixed to one another.

[0020] The application also relates to a system comprising a device for setting a setting element according to at least one of the embodiments described above or below and a tool exchange unit, wherein the tool exchange unit comprises a holding unit designed to temporarily fix the tool in a rotational manner in order to decouple the tool from the drive shaft. The system can in particular be designed to rotate the drive shaft relative to the tool in order to decouple the tool from the drive shaft. For example, the rotary drive can serve this purpose. In order to move the device to the tool exchange unit in an automated manner, the device can be attached to a robot arm.

[0021] According to one embodiment, the tool exchange unit may comprise a magazine for new tools. The new tools may comprise a plurality of similar and / or different tools.

[0022] The application also relates to a method for replacing a tool on a device or system for setting a setting element, comprising the steps:

[0023] - Providing a device or a system for setting a setting element, in particular a device or a system for setting a setting element according to at least one of the embodiments described above or below, with a rotary drive to drive the tool and / or a drive shaft in a rotational manner,

[0024] - Disengaging a clutch so that the tool is no longer coupled to the drive shaft,

[0025] - Replacing the tool with a new tool,

[0026] - Engaging the clutch so that the new tool is coupled to the drive shaft, wherein the disengagement and / or engagement of the clutch is carried out automatically by the device or by an external clutch actuating element.

[0027] The method according to the invention is based on the idea that the device or an external clutch actuating element automatically decouples the tool, allowing an automated tool change. This allows the device to be operated fully automatically, thus saving personnel costs and reducing downtime.

[0028] According to one embodiment, the device comprises a linear drive. In this case, the method can comprise moving the drive shaft and / or the tool by means of the linear motor. For example, the drive shaft and / or the tool can be moved in a first direction by means of the linear motor to engage the clutch. Alternatively or additionally, the drive shaft and / or the tool can be moved in a second direction opposite to the first direction by means of the linear motor to disengage the clutch. Thus, the linear motor can engage and disengage the clutch.

[0029] Alternatively, the clutch can be disengaged and / or engaged by means of a pneumatic valve or another actuator. Furthermore, an external clutch actuating element can be provided, for example, on a tool exchange unit or a changing station, which, when the device is positioned in a specific position relative to the clutch actuating element, is configured to engage and / or disengage the clutch.

[0030] According to one embodiment, the method comprises a

[0031] - Moving the tool and / or the drive shaft by means of the linear drive in a first direction in order to deform the setting element and

[0032] - Moving the tool and / or the drive shaft by means of the linear drive in a second direction opposite to the first direction in order to disengage the clutch.

[0033] The linear drive can therefore be used on the one hand to deform the setting element and on the other hand to disengage and / or engage the clutch.

[0034] According to one embodiment, disengaging the clutch causes the tool to no longer be rotationally coupled to the drive shaft, and engaging the clutch causes the new tool to be rotationally coupled to the drive shaft.

[0035] According to one embodiment, the drive shaft and the tool have corresponding threads in order to screw the tool into the drive shaft or onto the drive shaft at the end. In this case, replacing the tool can comprise: rotating the drive shaft relative to the tool in a first direction of rotation in order to unscrew the tool from the drive shaft and rotating the drive shaft relative to the tool in a second direction of rotation opposite to the first direction of rotation in order to screw the new tool onto the drive shaft or screw it into the drive shaft. Rotating the drive shaft is preferably carried out using the rotary drive. Alternatively, replacing the tool can comprise laterally removing the tool from the drive shaft or a holder and laterally inserting a new tool into the drive shaft or holder.

[0036] According to one embodiment, engaging and / or disengaging the clutch comprises an axial movement of a coupling element relative to the drive shaft. This allows the clutch to be engaged and / or disengaged in a simple and reliable manner.

[0037] According to one embodiment, disengaging the clutch comprises limiting the movement of a coupling element and subsequently allowing the drive shaft to move axially relative to the coupling element. The movement of the coupling element can be limited by a stop.

[0038] According to one embodiment, the subsequent axial movement of the drive shaft relative to the coupling element is carried out counter to a spring force. This allows a defined relative movement between the drive shaft and the coupling element to be achieved in a simple manner.

[0039] According to one embodiment, engaging the clutch involves axially mating a non-circular portion of the tool with a corresponding non-circular portion of a coupling element. This allows for a simple, releasable rotational fixation between the drive shaft and the tool.

[0048] Fig. 7 is a sketch of a method for replacing a tool on a device.

[0049] Fig. 1 shows a sectional view of a portion of a device 10 for setting a setting element. In the illustrated embodiment, the device 10 serves to set setting elements with a thread, such as a blind rivet nut, a blind rivet bolt, or a sealing plug, ie, to insert them into another component.

[0050] The device 10 comprises a receptacle 12 with a thread 12a. A tool 14, for example a mandrel, can be screwed into the thread 12a. In the present exemplary embodiment, the tool 14 has a threaded section 14a that extends along the entire outer surface of the tool 14. The threaded section 14a has a dual function: Firstly, the threaded section 14a serves to screw the tool 14 into the thread 12a of the receptacle 12. Secondly, the threaded section 14a serves to screw a setting element (not shown), for example a blind rivet nut, onto the tool 14 or into the tool 14.

[0051] The device 10 also includes a rotary drive 16 (shown schematically) for driving a drive shaft 18 in rotation, i.e., for setting it into rotation. The rotary drive 16 can be designed, for example, as an electric motor. The rotary drive 16 is designed to drive the drive shaft 18 in two mutually opposite directions of rotation.

[0052] The device 10 also comprises a linear drive 22. The linear drive 22 can, for example, comprise a planetary roller screw drive that converts a rotational movement into a linear movement. However, the linear drive 22 can also be designed in a different way. The linear drive 22 serves to move the drive shaft 18 in a first direction 24 along its main direction of extent and along a second direction 26 oriented opposite to the first direction 24. In the embodiment shown, the drive shaft 18 forms the receptacle 12 for the tool 14. As a result, in the embodiment shown, a linear movement of the drive shaft 18 always results in a linear movement of the tool 14 coupled to the drive shaft 18. In other words, the linear drive 22 serves to move the tool 14 in the first direction 24 and in the second direction 26.

[0053] The device 10 also includes a coupling 20. The coupling 20 serves to selectively couple the tool 14 to the drive shaft 18 or to decouple the tool 14 and the drive shaft 18. The coupling 20 includes a coupling element 20a, which is shown in detail in Fig. 5A. The coupling element 20a has a non-circular peripheral shape 20b, hexagonal in the illustrated embodiment. The non-circular peripheral shape 20b serves to engage with a corresponding non-circular peripheral shape 14b (see Fig. 4) of the tool 14 and thus to rotationally couple the coupling element 20a and the tool 14. The coupling element 20a is connected to an annular element 36 via a pin 34. The annular element surrounds the coupling element 20a and serves to limit an axial movement of the coupling element 20a during an axial movement of the drive shaft 18 in the second direction 26.For this purpose, the annular element 36 has a stop surface 36a. This stop surface 36a is designed to come into contact with a stop surface 28b (see Fig. 6A) of a support element 28 when the drive shaft 18 is moved further than a certain distance in the second direction 26.

[0054] The support element 28 is shown in Fig. 6A. In the present embodiment, the support element 28 is formed by a sleeve. The support element 28 forms an annular end face 28b. The end face 28b forms a stop for the annular element 36, i.e., the end face 28b is designed to come into contact with the stop surface 36a of the annular element 36 and prevent further movement of the annular element 36 and thus of the coupling element 20a.

[0055] The support element 28 also has a front-side contact surface 28a. The contact surface 28a is oriented opposite the front side 28b. The contact surface 28a serves to provide a contact surface 28a for the respective setting element when setting, for example, a blind rivet nut, a blind rivet bolt, or a sealing plug.

[0056] The support element 28 also has a guide surface 28c to limit movement of the tool 14 during an axial movement of the tool 14 along the guide surface 28c in the radial direction. The support element 28 can be fastened or is fastened during use to a housing 30 of the device 10 by means of a thread 28d. Fig. 5B shows the drive shaft 18. The drive shaft 18 forms the receptacle 12 for the tool 14 in a distal end region. The receptacle 12 has the thread 12a, an internal thread in the present embodiment, in a distal end region. This allows the tool 14 to be screwed into the drive shaft 18. The drive shaft 18 also forms a linear guide 18a for the coupling element 20a. The linear guide 18a can be adapted to a circumferential shape of the coupling element 20a with regard to its circumferential shape.This circumferential shape of the coupling element 20a can be designed differently than the circumferential shape 20b of the coupling element 20a, which comes into operative contact with the circumferential shape 14b of the tool 14. The linear guide 18a also serves to accommodate a spring element 32, which preloads the coupling element 20a in the distal direction 26. The drive shaft 18 also includes an elongated hole 18b. The elongated hole 18b serves to accommodate the pin 34 and to allow axial movement of the pin 34 and thus of the coupling element 20a and the annular element 36 along the drive shaft 18.

[0057] In the following, various states of the device 10, in particular of the coupling 20, are described with reference to Figs. 2 to 4. Fig. 2 shows a basic position of the device 10. In this basic position, the coupling 20 is engaged. In other words, the coupling element 20a engages with the tool 14 such that the coupling element 20a blocks a rotational movement of the tool 14. As a result, the tool 14 cannot be unscrewed from the receptacle 12. The spring element 32 presses the coupling element 20a in the distal direction 26 against the tool 14, so that the coupling element 20a is securely engaged with the tool 14. The annular element 36 is spaced from the stop 28b.

[0058] Fig. 3 shows a maximum working position of the device 10. When the device 10 is moved from the home position to the maximum working position, for example, a blind rivet nut (not shown) screwed onto the tool 14 is deformed by a part of the blind rivet nut equipped with an internal thread being pulled by the tool 14 in the proximal direction 24, while a part of the blind rivet nut not engaging with the tool 14 is pressed against the contact surface 28a of the support element 28. The device 10 is moved from the home position to the maximum working position by the linear drive 22 moving the drive shaft 18 and thus also the tool 14 in the proximal direction 24.

[0059] Fig. 4 shows the device 10 in a tool change position. The device 10 is moved from the home position into the tool change position by moving the drive shaft 18 and thus the tool 14 in the distal direction 26 by the linear drive 22. During the movement of the drive shaft 18 in the distal direction 26, the annular element 36 strikes the stop surface 28a of the support element 28. By further moving the drive shaft 18 in the distal direction 26, the tool 14 coupled to the drive shaft 18 moves further in the distal direction 26, while the coupling element 20a is prevented from moving in the distal direction 26 by an axial coupling with the annular element 36. Thus, an axial relative movement is generated between the tool 14 and the coupling element 20a, which leads to the coupling element 20a and the tool 14 being disengaged.As a result, the tool 14 can now be rotated relative to the holder 12, so that the tool 14 can be unscrewed from the holder 12. The spring element 32 is deformed and thereby presses the annular element 36 against the stop surface 28a.

[0060] Fig. 6B shows a system 100 by means of which it is possible to carry out a fully automated tool change on the device 10. For this purpose, the device 10 is preferably attached to a robot arm 50 in order to bring the device 10 into proximity with a tool exchange unit 104. However, it would also be possible for the device 10 to be arranged in a stationary manner. The tool exchange unit 104 comprises a holding unit 106 for temporarily fixing the tool 14 in rotation. When the device 10 is in the tool change position and the tool 14 is fixed in rotation by the holding unit 106, the tool 14 can be unscrewed from the drive shaft 18 by rotating the drive shaft 18 by means of the rotary drive 16.Accordingly, in the tool change position, a new tool 110 can be removed from a magazine 108 and screwed into the drive shaft 18 by rotating the drive shaft 18 by means of the rotary drive 16 relative to the tool 110.

[0061] By engaging and disengaging the clutch 20 by means of the linear drive 22 and decoupling and coupling the tool 14 to the drive shaft 18 by means of the rotary drive 16, no additional drive is required to provide a fully automatic tool changing system.

[0062] Fig. 7 outlines a method 200 for exchanging a tool 14 on a device 10 or a system 100 for setting a setting element. In a first step 210, the device 10 or the system 100 is prepared. Subsequently, in a second step 220, a clutch 20 of the device 10 is disengaged by the device 10 independently, i.e. automatically, so that the tool 14 is no longer coupled to a drive shaft 18. This can be effected, for example, as described above, by moving the device 10 from a home position to a tool change position. The device 10 preferably moves itself automatically from the home position to the tool change position. Subsequently, in a third step 230, the tool 14 is exchanged for a new tool 110. The new tool 110 can be a different type of tool or a tool that is not yet worn out.Replacing 230 the tool comprises rotating the drive shaft 18 and thus also a receptacle 12 relative to the tool 14 in a first direction of rotation in order to unscrew the tool 14 from the drive shaft 18 and the receptacle 12, and then rotating the drive shaft 18 together with the receptacle 12 relative to the tool in a second direction of rotation opposite to the first direction of rotation in order to screw the new tool 110 into the receptacle 12 of the drive shaft 18. The rotation of the drive shaft 18 is preferably also carried out automatically by the device 10, for example by a rotary drive 16 of the device 10. In a fourth step 240, the clutch 20 is re-engaged so that the new tool 110 is coupled to the drive shaft 18. This is also carried out automatically by the device. In a fifth step 250, a setting element can then be set using the new tool 110.
