Description

[0001] The invention relates to a movable production tool according to the preamble of claim 1, a device for coupling and uncoupling according to the preamble of claim 8 and a production system according to the preamble of claim 10 for changing at least two tool components of a production tool.

[0002] Various manufacturing tools for joining components are known from the prior art. These tools can be moved freely in space, either manually or with the aid of automated handling devices. This allows them to be moved along the outer edges of two components to join them together, moving from one processing point to the next. Components can be joined together, for example, by riveting or clinching. Such manufacturing tools are already known, for example, from DE 103 35 085 A1, DE 699 16 730 T2, and DE 27 00 502 A1.

[0003] When using such manufacturing tools in conjunction with automated handling devices and especially with industrial robots, flexible use of such tools is desirable in order to achieve favorable utilization of, for example, industrial robots.

[0004] The object of the present invention is to improve the production of joints on components and tools for this purpose in terms of efficiency and flexibility.

[0005] The object is achieved by a manufacturing tool having the features of claim 1, a device having the features of claim 9, a manufacturing system according to claim 11 and by a method according to claim 12.

[0006] Preferred and advantageous embodiments of the invention are set out in the subclaims.

[0007] The invention is based on a movable production tool for joining components, in particular by clinching, riveting, or press-fitting. The movable production tool comprises a frame and at least two interchangeable tool components designed to interact to form a joint. The tool components can be interchanged as often as required. Two coupling sections are formed on the frame such that at least one of the tool components can be releasably secured to each coupling section using a suitable component coupling.

[0008] The essence of the invention is that an arrangement of the coupling sections on the frame and the tool components are coordinated with one another in such a way that both tool components can be removed from the frame and attached to the frame at the same time. By "at the same time" is meant that the process of coupling or uncoupling one of the tool components to the frame is at least not yet completed when the corresponding process for the second tool component begins. Preferably, the time period in which several tool components are simultaneously in a coupling or uncoupling process is longer than the sum of the durations in which not all tool components affected by a coupling or uncoupling process are participating in the respective process, wherein a gripping contour is formed in a region of the component coupling of the tool component.

[0009] By essentially coupling and uncoupling tool components in parallel, the duration of such a process can be reduced to that required for the tool component or coupling section that requires the longest time for the respective process compared to the other tool components or coupling sections. In most cases, this time can be shorter than the time required for coupling and uncoupling in which tool components are coupled and uncoupled one after the other. This advantageously allows for shorter tool changeover times, enabling shorter production cycle times and higher throughput rates in production plants.In addition, a manufacturing tool according to the invention can also offer advantages with regard to its space requirements during a tool change because, when coupling and uncoupling individual tool components, spatial areas must be freely accessible at the respective change positions to which tool components that are still coupled or remain coupled can be moved during a coupling or uncoupling process.

[0010] The manufacturing tool according to the invention offers the advantage that the tool components can be coupled and uncoupled in pairs comparatively quickly, which enables faster tool changes and thus higher cycle rates in an automated manufacturing plant.

[0011] The production tool and, in particular, the tool components can be designed for riveting or clinching, for example. By exchanging appropriate tool components, the production tool can also be used for both forming joining techniques. Furthermore, it can be used for other manufacturing processes, such as press-fit joining or punching, in which, for example, two tool parts act on one or more components from different, particularly opposite, sides.

[0012] The frame of the production tool can be curved, e.g., C-shaped. Preferably, the coupling sections are arranged at opposite ends of an arcuate frame, so that the frame can encompass one or more components to be machined from an edge area and the tool components can be arranged on opposite sides of the components.

[0013] The coupling sections of the frame and the component couplings can, for example, mesh at right angles to a direction of a working movement. This allows for a comparatively simple simultaneous coupling and uncoupling of several tool components to the frame. If the coupling sections and the component couplings mesh in a direction parallel to a working movement, machining forces can advantageously contribute to the holding forces with which the tool components are held in the coupling. In particular, shear forces on parts of the couplings can be advantageously reduced or completely avoided in this way.

[0014] The tool components can, for example, be coordinated in their dimensions in such a way that both tool components can be placed simultaneously in a position ready for coupling, e.g., between the two coupling sections. For example, by moving the tool components apart after such placement, the component couplings of the tool components can be inserted into the respective coupling sections of the frame. Preferably, the direction and depth of the mutual engagement of the component couplings and the coupling sections are taken into account in such a way that coupling can be initiated and uncoupling can be completed simultaneously.This offers the advantage that simultaneous movements of both tool components, on the one hand for placing the tool components between the coupling sections and on the other hand for inserting the component couplings into the coupling sections of the frame, are decoupled from each other and can be carried out with different levels of accuracy if necessary.

[0015] A preferred embodiment of the invention consists in that at least one coupling section of the frame is formed on a movable part of the frame. As a result, the coupling section attached to the movable part of the frame can be displaced relative to another coupling section of the frame in such a way that two or, if necessary, more tool components can be coupled or disconnected simultaneously. A drive device with which, for example, a lifting movement for a work step can be carried out can therefore also be advantageously used for positioning the coupling sections for a simultaneous change of tool components, in particular when lifting movements and movements for connecting the coupling sections to the component couplings run parallel.

[0016] Preferably, the coupling sections of the frame are located opposite each other along a directional axis of a working movement of the production tool on the frame. This allows labor to be transferred from tool components to the frame via the component coupling and the coupling sections during a machining operation.

[0017] Preferably, engagement elements with which a coupling section and a component coupling engage are designed to align the tool components with respect to a movement path of the tool components during a working movement, in particular perpendicular to the direction of movement. If engagement elements are formed on both coupling sections, each of which can engage a component coupling, it is preferred that the engagement elements be designed such that the tool components do not interfere with each other and, in particular, do not touch each other when simultaneously removed from an engaged position.

[0018] Preferably, at least one of the coupling sections of the frame is provided with a connection for a working medium, by means of which the working medium can be fed to a coupled tool component. Such a connection can also be provided to return a working medium from a coupled tool component. The working medium can be, for example, compressed air or a hydraulic fluid, which can be used to mechanically transmit energy. This can be used to drive a moving part of a tool component, e.g., a riveting die.

[0019] The working medium can also be an auxiliary material for a machining process, e.g. a cleaning agent with which a joint is sprayed before a joining process. Furthermore, a connection for a measuring unit for a tool component can also be formed on a coupling section. For example, a coupling section can be provided for attaching a clinching punch. In order to monitor the condition of the clinching punch, the coupling section can have, for example, two compressed air connections, one each as a supply line and a return line. Using the compressed air connections, a dynamic pressure test can be carried out by blowing a compressed air pulse onto the punch tip. The return connection can be provided to feed the air returned from the punch tip to a measuring device.

[0020] According to the invention, a gripping contour is formed on a component coupling of a tool component. This offers the advantage of more precise and therefore faster positioning of a tool component when coupling and uncoupling the tool component to the frame.

[0021] Preferably, means for locking a tool component are formed on a component coupling of the tool component. In particular, if external actuation is provided for the locking means, a comparatively simpler design of the production tool can be achieved.

[0022] A further object of the invention is a device for coupling and uncoupling tool components of a production tool according to the invention, wherein the device comprises two gripping devices. Each gripping device is provided for a respective tool component. The device is distinguished according to the invention in that the gripping devices are designed such that two tool components can be simultaneously gripped and attached to the production tool in a predetermined position of the production tool relative to the device on the production tool. With such a device, a comparatively rapid change of tool components on a tool can advantageously be carried out.

[0023] The gripping devices can be, for example, mechanical grippers with, for example, two gripping jaws or electromagnetic gripping devices which can hold the tool components essentially with magnetic forces. For example, the gripping devices can be provided to hold the tool components, in particular to engage them when the tool components are positioned with the frame in a predetermined position relative to the device. While the gripping devices hold the tool components, the tool components can be coupled, for example, by bringing the frame closer and uncoupled by moving the frame away. Likewise, the device can have movement means with which, for example, two gripping devices can be moved closer to and away from a stationary frame, in particular simultaneously, in order to couple and uncouple tool components.Preferably, the movement means of the device are designed to displace tool components from the frame of the production tool during uncoupling at a distance that can be adjusted to the positioning accuracy or path accuracy of a handling device. This advantageously prevents collisions with the tool components when moving the frame away from and towards it.

[0024] Furthermore, it is preferred that an adjusting device is formed on at least one of the gripping devices, with which a tool component attached to the production tool can be locked and unlocked. This advantageously simplifies the structure of a production tool according to the invention.

[0025] A production tool according to the invention and a device according to the invention for coupling and uncoupling tool components together form a production system, which is also the subject of the invention. Several devices can be provided for one production tool, on which tool components can be provided. Likewise, a device for several production tools can be provided for the simultaneous changing of several tool components.

[0026] A further object of the invention is a method for coupling and uncoupling, in particular for changing at least two tool components on a production tool for assembling components, which has coupling sections for the releasable attachment of the tool components. The essential feature of the method is that at least two of the tool components are simultaneously gripped for coupling and uncoupling, in particular by a device provided for this purpose, and moved relative to the coupling sections. This advantageously shortens changeover times for a production tool.

[0027] An embodiment of the invention will be explained in more detail below with reference to the drawings.

[0028] As an example of a manufacturing tool according to the invention, the Fig. 1 a clinching pliers 1. The clinching pliers 1 comprise a frame 8 from which an upper frame arm 8a and a lower frame arm 8b protrude. The frame 8 has mounting plates 9 with which the clinching pliers 1 can be attached, for example, to an industrial robot.

[0029] On the upper frame arm 8a, for example, a hydraulic drive unit is attached, with which a lifting ram 11 can be moved up and down. At the end of the lifting ram 11, a coupling unit is formed, with which a punch 2 is fastened to the coupling element 4 and thus to the lifting ram 11 by means of its coupling element 5. On the lower frame arm 8b, at a point opposite the coupling unit 4, a further coupling unit is formed, with which, for example, a die 3 can be fixed to the lower frame arm 8b via its coupling element 6. The drive unit 10 can move the lifting ram 11 and thus the punch 2 away from the die 3 or towards it. When the punch 2 and the die 3 are in a separate position, two sheets (not shown), for example, can be brought into the section and a clinch connection can be produced by closing, i.e. by bringing the punch closer to the die 3.

[0030] In Fig. 2a shows a manufacturing system 51 according to the invention, which comprises the clinching pliers 1 and a changing station 13. A frame 20 of the changing station 13 has a base element 22, which allows a column element 21 to stand vertically. A mounting plate 19 is attached to the column element 21. The mounting plate 19 is provided with holes 23, to which up to three supply units 14 can be attached. In the Fig. In the example of a changing station 13 shown in Figure 2b, provision units 14 are attached only at a first and a second mounting position. Therefore, the holes 23 for attaching a provision unit 14 are visible at an unequipped third mounting position.

[0031] A supply unit 14, which serves as a device for coupling and uncoupling tool components 2, 3, is in Fig. 3 is shown enlarged. Exposed lines such as cables and compressed air hoses are Fig. 3 as well as in the following Fig. 4 - 6, in contrast to corresponding connections 34, are not shown for the sake of better clarity.

[0032] All parts of the provision unit 14 are connected to one another via an attachment element 30 and, in particular, its base plate 31. The base plate 31 has fastening elements 32 with which the provision unit can be fastened, for example, to the mounting plate 19. An upper and a lower connecting body 33 are attached to the base plate 31. An upper lifting unit 17 is attached to the upper connecting body 33, and a lower lifting unit 18 is attached to the lower connecting body 33.

[0033] The lifting unit 17 comprises a lifting piston 36, with which an upper gripper 15 can be displaced in the vertical direction. A lower gripper 16 is attached to the lower lifting unit 18 in a corresponding manner. The lifting units 17, 18 are pneumatically driven. The upper gripper 15 is connected to the lifting piston 36 via a connecting element 37. The gripper 15 consists of a drive unit 29, in which a left and a right gripper arm 24 are movably mounted and can be moved apart and pulled together by the drive unit 29. In a joined position, the gripper arms 24 form a U-shaped fork with which a tool component 2, 3 can be gripped. A further lifting unit 18 is attached to the lower connecting body 33 and is provided for displacing a second gripper 29.Because the grippers 15, 16 are designed to remove or attach tool components from or to opposite positions, performing opposing movements, the lifting units 17, 18 are laterally offset from a central vertical cutting plane. This enables a more compact design of the supply unit 14 because collisions between the lifting pistons 36 of the lifting units 17, 18 can be avoided.

[0034] To ensure a secure hold, a gripping contour 28 with a triangular cross-section is formed on the gripping arms 24, which extends into a gripping area between the gripping arms 24. To prevent displacement along the engaging edge, a gripping pin 27 is formed in a front area of ​​the gripping arms 24, which can engage in a corresponding recess on an engagement profile of a tool component. Adjusting devices 25 are mounted in the protruding end area of ​​each of the gripping arms 24, with which an adjusting bolt 26 can be extended and retracted. These adjusting devices can be used to actuate a locking mechanism on the tool components.

[0035] The stroke of the lifting devices 17, 18 is primarily coordinated with the mutual engagement of the coupling sections 4, 7 on the tool frame and on the component couplings 5, 6. The stroke of each gripper 15, 16 corresponds at least to the depth of engagement of the coupling parts 4, 5, 6 and 7. Depending on the size of the distance between the tool components after the couplings are released from their engagement, the tool components on the upper and lower grippers 15, 16 can be additionally brought closer to one another in order to reduce the risk of a collision between the tool frame 8 and the tool components 2, 3 and, if necessary, to be able to move the tool frame 8 away from or towards an occupied supply unit 14 more quickly.

[0036] The Fig. Fig. 4 shows the punch 2, which comprises a substantially cylindrical punch unit 47 and a coupling 5 as a component coupling. A punch tip 48 of the punch element 47 is intended to be used together with a die 3 ( Fig. 6) to create a clinch connection on a component (not shown).

[0037] A gripping groove 39 is formed on the coupling 5, which extends in a V-shape around the coupling 5 in a plane perpendicular to a punch axis. The gripping groove 39 and the gripping profile 28 of the gripping arms 24 of the grippers 15 and 16 are coordinated with one another in such a way that the punch 2 and in particular the coupling 5 maintain their alignment, in particular even when a gripper 15 or 16 is moved.

[0038] In the area of ​​the gripping groove 39, an engagement bore 40 is formed at opposite points on the coupling 5, into which the gripping pin 27 of the gripping arms 24 can engage. This allows the positioning of the coupling 5 to be controlled relatively precisely during coupling and uncoupling. In particular, the engagement bore is arranged such that when a gripper 15 or 16 engages, the adjusting devices 25 on the gripping arms 24 assume a predetermined position relative to a locking bolt 38. The locking bolt 38 is displaceably mounted on the coupling 5. With one of the adjusting devices 25, the locking bolt can be moved into a locked position, and with an adjusting device 25 attached to the opposite gripping arm, it can be moved into an unlocked position.Because the locking bolt 38 can be actuated by the supply unit, the production tool is relieved of this task and can therefore advantageously be constructed more simply.

[0039] The Fig. 5 shows an end face of the coupling 5, with which the coupling 5 can rest against one of the couplings 4, 7 of the frame 8. The coupling 5 has a centering opening 46 into which a centering pin (not shown) of the couplings 4 and 7 can engage. The centering pin also has a recess into which the locking bolt 38 can engage in a retracted position. As a result, after inserting the centering pin into the centering opening 46, the punch 2 can be locked in a position aligned with the die 3. In order to hold the locking bolt 38 in a locking and a non-locking position, a locking pin 42 is movably mounted in the coupling 5 and is acted upon by a spring 43. The fixing pin 42 can engage in grooves 50 on the locking bolt 38 in order to hold the locking bolt 38 in any position of the punch 2 in the coupling 5.

[0040] An indicator pin 41 is connected to the locking bolt 38 and can be moved into a bore 49 on the coupling 5 when the locking bolt 38 is in the locked position. The couplings 4 and 7 each have a sensor, preferably an induction sensor, which indicates the position of the indicator pin 41 in the coupling counterpart 5 and 6. This makes it possible to check whether the couplings 4 and 5 or 6 and 7 are correctly coupled to one another. A spray agent connection 45 and two compressed air connections 44 are arranged next to the centering opening 46. One of the compressed air connections 44 is provided as a supply and the second as a return for compressed air. The compressed air connections used on the coupling 5 are provided with connecting pieces 44a, in particular sealing. The returning compressed air connection 44 can, for example, be used to connect a pressure redirected orA reflected compressed air pulse, which can be supplied through the supplying compressed air connection, can be fed to a measuring device (not shown) for a dynamic pressure test in order to check the condition of, for example, the punch tip 48 or the die 3 based on a reflected portion of a compressed air pulse. The spray medium connection 45 is provided, for example, to provide a spray medium for preparing a clinching process of a workpiece (not shown), which spray medium can be sprayed, for example, from the punch 2 onto a processing point.

[0041] The Fig. The die 3 shown in Figure 6 is, similar to the punch 2, composed of a die unit 52 and the coupling 6. The structure of the coupling 6 is essentially the same as that of the coupling 5, particularly with regard to the engagement contours 39, 40, the centering opening 46, and the locking mechanism 38, 41, 42, 43, 49. The die 3 is also provided for spraying the component during a work step, so that a supply compressed air connection 44 and a spray agent connection 45 are formed on the coupling 6. No dynamic pressure test is provided for a working surface 53 of the die unit 52, so that only the supply compressed air connection 44 is formed on the coupling 6.

[0042] The couplings 5, 6 of the punch 2 and the die 3 are designed in such a similar way that each of the couplings 5 ​​and 6 can be attached to each of the couplings 4 and 7. The couplings 5, 6 and 4, 7 can each be made from identical base bodies that can be connected to the respective tool element. This advantageously enables efficient production of the interchangeable tool components 2, 3.

[0043] A further advantage is that the production tool 1 and the changing station 13, in particular their supply units 14, can be constructed comparatively simply because, due to the many similarities between the couplings 5 ​​and 6, identical or very similar components can be used on these devices for an upper and a lower tool component 2, 3. As shown in the Fig. 2a and Fig. As can be seen in Figure 2b, the changing station 13 with two provision units 14 can be used to easily swap the positions of the punch 2 and the die 3 on the clinching pliers 1. Regripping the clinching pliers 1 by rotating them through a 180° angle is unnecessary. The clinching pliers 1 can, for example, deposit a set of tool components with a punch 2 at the top and a die 3 at the bottom in the second provision unit 14. The clinching pliers 1 can then pick up a second set of tool components 2, 3 in an inverted arrangement from the first provision unit 14.

[0044] The following describes the simultaneous uncoupling of punch 2 and die 3 from the clinching pliers 1 as an example of a simultaneous tool change. Coupling can be performed in a correspondingly reversed sequence, for example.

[0045] A provision unit 14 can be placed in a state suitable for uncoupling by opening the gripper arms 24 of all grippers 15, 16 and, for example, extending the upper lifting unit 17 so far that the travel path when lowering the gripper 15 is at least sufficient to move the coupling 5 out of, for example, an engagement of the coupling 4. As a result, the position of the upper gripper arms 24 and in particular the gripper pins 27 can advantageously be used as a reference position for approaching the clinching pliers 1. Furthermore, only a vertical positioning of the lower gripper arms 24 is subsequently required, which is comparatively easier to control individually.

[0046] With the production tool 1, the punch 2 can be guided between the gripping arms 24 of the upper gripper 15. At the same time, the die 3 can be placed between the gripping arms 24 of the lower gripper 16. The drive units 29 can pull the gripping arms 24 together so that the gripping contours 28, 27 of the gripping arms 24 can simultaneously engage the engagement contours 39, 40 of the punch 2 and the die 3.

[0047] The accuracy of the positioning of the clinching pliers 1 is possible with the help of the gripping pins 27 on the gripping arms 24 and the engagement holes 40 on the couplings 5 ​​and 6. These can block a complete closing of the gripping arms 24, whereby a misalignment of the clinching pliers 1 for a decoupling maneuver can be detected. When the gripping pins 27 fully retract into the engagement holes 40, the adjusting devices 25 on the gripping arms 24 are then also in positions in which their adjusting bolts 26 can act on the locking bolt 38 of the couplings 5 ​​and 6. By means of a compressed air pulse, for example, the upper right adjusting device 25 with its adjusting bolt can move the locking bolt 38 into an unlocking position, as shown in Fig. 5. Accordingly, a lock on the die 3 is released at the coupling 6, e.g., with a compressed air pulse on the left-hand adjusting device 25. Subsequently, the grippers 15 and 16 are simultaneously moved towards one another by the lifting units 17 and 18, with the gripper arms 24 closed and engaging the couplings 5 ​​and 6, until none of the couplings 5 ​​and 6 is engaged with the couplings 4 and 7. The tool components 2, 3 are thus uncoupled and the clinching pliers 1 can be moved away from the tool components 2, 3, at least horizontally.

[0048] In the case of the Fig. 2b, the clinching pliers 1 can be moved, for example, parallel to the plane of the mounting plate 19 to the adjacent provision unit 14 and, for example, couple the punch 2 to the coupling 7 and the die 3 to the coupling 4 there.
