Definitions

  • the present invention relates to a clamping device for clamping a cable during an assembly process.
  • the method further relates to a method for holding a component on a cable during an assembly process.
  • Cable assembly is generally understood to mean the manufacture of cables ready for connection. Both a single cable and a combination of several individual cables can be referred to as a cable. Accordingly, assembly can produce single wires ready for connection or a single wire combination. Assembly can involve the manufacture of a few, possibly bundled, single wires with connectors or, in more complex cases, the manufacture of entire cable harnesses and on-board networks, e.g. for use in an automobile.
  • individual cables must regularly be held at least temporarily in a desired position and/or, for example, their free end must be moved to a desired position.
  • a cable can be placed in a clamping device and then temporarily held in place by this clamping device.
  • the clamping device can then be moved together with the cable, for example, to the desired position.
  • a free end of the cable can then be stripped and/or provided with a connection, for example by crimping the connection.
  • clamping device that provides additional functionalities in addition to the conventional clamping of cables.
  • the clamping device should be able to be used advantageously in assembly processes in which at least one other component is to be handled in addition to the cable.
  • a method for holding a cable during an assembly process that advantageously uses the additional functionalities of the clamping device.
  • a clamping device for clamping an elongated cable during an assembly process.
  • the clamping device comprises a clamping device and a holding device.
  • the clamping device has two clamping jaws which can be reversibly displaced relative to one another between a release configuration and a clamping configuration in a clamping direction transverse to a longitudinal extension direction of the cable and which delimit a cable receiving volume between them.
  • the clamping device is designed to hold the cable arranged in the cable receiving volume fixed in the clamping configuration relative to the clamping device and to release the cable from the clamping device in the release configuration.
  • the holding device is designed to hold a component which is pushed onto the cable in the axial direction and which at least partially surrounds the cable.
  • the holding device is attached to the clamping device and configured to hold the component in a force-fitting and/or form-fitting manner relative to the cable.
  • the additional component directly to the cable in such a way that it holds sufficiently firmly to the cable so that it can then be moved together with the cable in further process steps.
  • the additional component it would be conceivable to design and dimension the additional component in such a way that it can grip around the cable and is held force-fittingly to the cable, for example due to static friction.
  • a component in the form of a sleeve with a sufficiently small inner diameter could be pushed axially onto the cable and then held against it by friction.
  • automated, mechanical handling of the cable and the component in particular can be complex and/or not sufficiently reliable in such a case.
  • the clamping device serves to temporarily clamp the cable to be assembled and thus hold it.
  • the holding device is specially configured to temporarily and reversibly hold a component that has been pushed onto the cable in the axial direction and which at least partially surrounds the cable in a fixed position relative to the cable.
  • the holding device is attached to the clamping device and is also configured to hold the component in a force-fitting and/or form-fitting manner relative to the clamping device and thus relative to the cable.
  • the component can be held in a desired position relative to the cable during the assembly process without the component itself necessarily interacting with the cable in a force-fitting or form-fitting manner. Accordingly, the component can be arranged on the cable in a simple manner and/or with little force, preferably mechanically, by sliding it loosely onto the cable in the axial direction.
  • the cable can then be moved together with the component held firmly relative to it, for example, to a desired position in order to process it further there, i.e., for example, to insulate the free end of the cable, to attach a connection and/or to carry out other assembly measures.
  • One or more assembly measures can then be carried out beforehand, simultaneously or subsequently with regard to the component held on the cable, i.e. the sleeve-like component, for example, can be fixed to the cable by pressing, for example.
  • the clamping device has a clamping device and a holding device.
  • the clamping device can be designed and function in the same or similar way as a clamping device of a conventional clamping device and can be used in particular to reliably hold and, if necessary, position a cable during the assembly process.
  • the holding device which is not present in conventional clamping devices, is designed to hold another component in addition to the cable. The other component can be held by the holding device specifically in a predetermined position relative to the cable.
  • the clamping device has at least two clamping jaws.
  • Each of the clamping jaws can be elongated.
  • the clamping jaws can be arranged in a clamping direction, ie in a direction transverse (preferably perpendicular) to the longitudinal extension direction of the cable to be held by the clamping device or in a direction transverse (preferably perpendicular) to the longitudinal extension of the Clamping jaws can be moved relative to one another.
  • the clamping jaws should be able to be moved towards or away from one another in the clamping direction.
  • the movement should be reversible.
  • the clamping jaws can be moved between a clamping configuration and a release configuration. In the release configuration, the clamping jaws are generally further apart than in the clamping configuration.
  • the clamping device fixes the cable arranged in the cable receiving volume relative to the clamping device by the clamping jaws clamping the cable between them from opposite sides.
  • the cable is held by the clamping device, when it is in its clamping configuration, in such a way that it can only be moved relative to the clamping device with great force and possibly not without damage.
  • the clamping jaws do not clamp the cable, so that the cable is released from the clamping device and can therefore be moved relative to it and, in particular, can be moved out of the clamping device.
  • the clamping jaws are preferably configured in terms of their geometric design and/or their material in such a way that they do not deform significantly under the forces that act during a clamping process for clamping a cable.
  • the holding device is specially configured to hold the additional component in a force-fitting and/or form-fitting manner in a desired position relative to the cable during the assembly process.
  • the holding device is attached to the clamping device, i.e. the holding device can be directly part of the clamping device or at least be mechanically connected to the clamping device.
  • the holding device can be implemented in different ways.
  • the holding device comprises, for example, at least one pressing element which is configured to press elastically against a side surface of the component transversely to the longitudinal extension direction.
  • the holding device can have a component which is referred to herein as a pressing element.
  • the pressing element is designed in terms of its geometric design, its material and/or its spatial arrangement to press elastically against the side surface of the component to be held when the latter has been pushed axially onto the cable held in the clamping device and then pushed so far towards the clamping device that it interacts with its holding device.
  • the pressing element is preferably designed and arranged in such a way that at least some of it borders on the cable receiving volume or slightly protrudes into this cable receiving volume.
  • the pressing element should press against the side surface of the component with at least such a force that the component is held by the holding device relative to the cable in a manner that is sufficient for the application.
  • the pressing element should be designed in such a way that the force applied to hold the component acts transversely, in particular perpendicularly, to the longitudinal direction of the cable.
  • the force should act elastically, i.e. in a resilient manner. Accordingly, the frictional connection between the component and the pressing element caused by this force and, optionally, a positive connection also caused by this should be reversibly releasable.
  • the component should be able to be reversibly released from the holding device by applying a sufficiently high force.
  • the component should first be able to be pushed onto the cable in the axial direction and introduced into the holding device with sufficient force in order to then be held by the holding device, whereby the component can be released from the holding device again, for example in a subsequent process step or at the end of the configuration process, for example by a force applied in the opposite direction.
  • the holding device can comprise two pressing elements which are configured to press elastically against a side surface of the component from opposite sides and transversely to the longitudinal extension direction.
  • the holding device can clamp the component from opposite sides with two pressing elements.
  • the two pressing elements are preferably designed and arranged in such a way that at least some of them border on the cable receiving volume from opposite sides or protrude slightly into this cable receiving volume.
  • the pressing element is formed with an elastically deformable spring component which is arranged on at least one of the clamping jaws.
  • the one pressing element or each of several pressing elements has a component that is elastically deformable and is therefore referred to herein as a spring component.
  • the spring component should be arranged on at least one of the clamping jaws.
  • the spring component can be fixed directly to one of the clamping jaws, be an integral part of one of the clamping jaws or at least be in mechanical contact with one of the clamping jaws.
  • the spring component can be designed and arranged so that a spring force caused by it is caused in a direction transverse, in particular perpendicular, to the longitudinal extension direction of the cable and thus acts from the side on the component to be held.
  • the spring component can also be designed to cause a spring force that is on the one hand sufficiently high to fix the component in the desired manner relative to the cable, but on the other hand is also sufficiently low to be able to release the component from the holding device reversibly and without damage if necessary.
  • the spring component can be formed with an elastically springy material.
  • the spring component can be designed as a metallic component in the form of a leaf spring, torsion spring, coil spring or the like or can comprise such a component.
  • the spring component can be formed with a plastic, in particular an elastomer.
  • the pressing element is coupled to the clamping device in such a way that the frictional connection or form-fitting connection with the component only occurs passively and resiliently and without active movement of the pressing element relative to the clamping device.
  • the holding device can be provided with one or more pressing elements such that they are firmly attached to the clamping device at least at one end or a partial area.
  • one of the pressing elements should be firmly attached to one of the clamping jaws of the clamping device at least in part, for example with its spring component.
  • a partial area of the pressing element attached to the clamping device is not active relative to to the clamping device, ie movable and/or pivotable, but only passively follows movements of the clamping device.
  • Such a design of the holding device with pressing elements, which are arranged at least in some areas rigidly on the clamping jaws of the clamping device is easy to manufacture and enables easy operation of the clamping device.
  • the pressing element attached to the respective clamping jaw is also passively displaced.
  • the pressing element is arranged and designed in such a way that when the clamping device is brought into its clamping configuration, it rests laterally against the component to be held and holds it in a force-fitting and/or form-fitting manner. Since the pressing element or the multiple pressing elements are held in a fixed relative position in relation to the clamping device, the component is also held in a fixed relative position in relation to the clamped cable.
  • the spring component is formed with a curved spring plate, which is attached with at least one end to one of the clamping jaws and which projects with a partial area towards the cable receiving volume.
  • the spring component can be formed with a thin metal sheet strip which is bent in such a way that it is attached to the associated clamping jaw in a partial area near the end and protrudes with another partial area towards the cable receiving volume.
  • the spring sheet can be formed by punching and/or bending a sheet, in particular a sheet metal strip. Due to its elastic properties, the spring sheet can be bent radially outwards, i.e. away from the cable receiving volume, by the component when it is pushed axially onto the cable and then pushed into the holding device, thereby exerting the force required for holding on the component.
  • the spring sheet can be attached or fastened to the clamping jaw in any way, for example by means of a screw connection.
  • the spring component is formed with two spring clips, which are each attached to at least one end of one of the clamping jaws and which extend with at least a partial region parallel to each other and parallel to the longitudinal extension direction of the cable.
  • the spring component can be designed with at least two brackets which have a curved geometry such that they have springy properties.
  • a spring bracket can be implemented in the form of a bent wire.
  • the spring bracket can be elastically deformable in a direction radially towards and away from the cable receiving volume.
  • the spring bracket can be elastically deformable in a direction laterally, in particular tangentially, in relation to the cable receiving volume.
  • One end or both opposite ends of the spring bracket can be attached to the associated clamping jaw.
  • the respective end can be fixed to the clamping jaw, for example with a fastening device such as a screw or the like.
  • the end of the spring bracket can be cast into a material of the clamping jaw, for example, or glued into a recess in the clamping jaw.
  • the two spring brackets extend at least partially parallel to one another and parallel to the longitudinal extension direction of the cable. Accordingly, the two spring clips can rest on the cable surface in different regions when inserted into the cable receiving volume and fix the cable in this way.
  • the spring component is formed with a pressure piece and a compression spring, which are configured to preload the pressure piece by means of the compression spring towards the cable receiving volume.
  • the spring component can have a pressure piece that is elastically pre-tensioned by a compression spring in a direction towards the cable receiving volume.
  • the pressure piece can have a geometry in order to be able to rest as large as possible on the outer surface of the cable received in the cable receiving volume.
  • a surface of the pressure piece facing the cable can have a partially cylindrical geometry.
  • the pressure piece can be made from a metal sheet and can in particular be a simple stamped and bent component. Any elastically deformable component such as a coil spring, a leaf spring, a torsion spring or an elastomer element can be used as the compression spring.
  • the spring component is formed integrally with one of the clamping jaws.
  • the spring component can be formed as an integral part in one of the clamping jaws or in both clamping jaws.
  • the spring component is in one piece with the rest of the clamping jaw.
  • the part of the clamping jaw that forms the spring component can be given the desired elastic properties by making this part of the same material as the rest of the clamping jaw, but having a different geometric shape and, in particular, smaller dimensions.
  • the spring component can be designed as an elongated, thin section at one end of the clamping jaw, which can be deformed transversely to its longitudinal extension with relatively small forces, whereas the rest of the clamping jaw is made thicker and thus does not experience any significant deformation with the forces required to clamp the cable.
  • the clamping jaw can be designed as a plastic component, in particular as an injection-molded plastic component.
  • the clamping jaw can be made of a metal material. It is also conceivable to use a combination of different materials and/or composite materials to form the clamping jaw.
  • the spring component can be attached to this clamping jaw as a separate component. Attachment can be reversible, for example using one or more screws. Attachment can also be irreversible, for example by casting parts of the spring component into the plastic component, gluing them in, etc. As a further alternative, the spring element can be formed integrally with a remainder of the clamping jaw.
  • the pressing element is configured to press elastically against a side surface of the component in a direction parallel to the clamping direction.
  • the pressing element thus exerts a force on a component that has been pushed axially onto the cable accommodated in the cable receiving volume, which force acts essentially in the same direction or parallel to the direction in which the clamping jaws exert the clamping forces to hold the cable.
  • Both the cable and the separate component can be held particularly efficiently if both are subjected to force from opposite sides, with the cable being held clamped between the clamping jaws and the separate component being held between two pressing elements, each of which extends from one of the clamping jaws or is mechanically connected to it.
  • the pressing element is configured to press elastically against a side surface of the component in a direction transverse to the clamping direction.
  • the pressing element thus exerts a force on the component pushed onto the cable, which is directed transversely, preferably perpendicularly, to the forces exerted by the clamping jaws for holding the cable.
  • the forces exerted for holding the separate component can be exerted by the pressing element essentially independently of the forces exerted for clamping the cable.
  • the clamping device further comprises an actuator which is configured to automatically displace the clamping jaws of the clamping device in the clamping direction.
  • the clamping device can in principle be designed such that the clamping jaws are moved between their clamping configuration and their release configuration manually or by a device separate from the clamping device.
  • the actuator can, for example, have an electric drive, a hydraulic drive, a pneumatic drive or the like.
  • a component is held on a cable during an assembly process.
  • the component is held in a fixed position relative to the cable during the assembly process using the clamping device described herein.
  • the cable is introduced into the cable receiving volume of the clamping device and then the clamping jaws of the clamping device are moved into their clamping configuration in order to clamp the cable in this way.
  • the component to be held is pushed onto the cable in the axial direction.
  • the component is designed in such a way that it holds the cable at least partially or at certain points or preferably completely in a ring shape.
  • the component is pushed onto the cable in such a way that it interacts with the holding device of the clamping device and is held by it in a force-fitting and/or form-fitting manner relative to the cable.
  • the component can in particular be pushed onto the cable so far that it reaches the area of the pressing element of the holding device, so that this can press elastically against the side surface of the component and in this way fix the component relative to the rest of the clamping device.
  • the component is designed as a cylindrical sleeve.
  • the component can be designed as a sleeve with a circular ring-shaped cross-section.
  • An inner diameter of the sleeve can preferably be at least slightly larger than an outer diameter of the cable, so that the sleeve can be pushed axially onto the cable loosely and essentially without friction.
  • the component can thus be arranged on the cable easily and without having to exert considerable forces in the axial direction.
  • the component is formed with a metallic material.
  • a component such as a sleeve made of metallic material can, on the one hand, have a high mechanical load-bearing capacity and/or good plastic deformability.
  • a metallic component even when in mechanical contact with a mostly plastic-based outer insulation of the cable, can at best cause low frictional forces when axially displaced relative to the cable, so that the metallic component can hardly be held in position relative to the cable by such frictional forces alone. It is therefore particularly advantageous for such a metallic component if it can be held relative to the cable using the holding device of the clamping device described here, as long as the cable is clamped in the clamping device during an assembly process and is possibly moved with it to various processing stations.
  • Figure 1 shows a first embodiment of a clamping device 1.
  • Figure 2 shows an overall clamping arrangement 47 which is equipped with such a clamping device 1.
  • the clamping device 1 is used to clamp an elongated cable 3 during an assembly process.
  • the clamping device 1 has a clamping device 5 with two clamping jaws 7 for this purpose.
  • the clamping jaws 7 can be reversibly displaced relative to one another between a release configuration and a clamping configuration in a clamping direction 9 which runs perpendicular to a longitudinal extension direction 11 of the cable 3.
  • the clamping jaws 7 delimit a cable receiving volume 13 between them, in which the cable 3 is to be inserted and clamped.
  • a surface of each clamping jaw 7 directed towards the cable receiving volume 13 can have a shape that is complementary to a jacket surface of the cable 3, i.e. it can be semi-cylindrical or partially cylindrical, for example.
  • the clamping jaws 7 are far enough apart from one another in relation to the clamping direction 9 that the cable 3 can be pushed or inserted into the cable receiving volume 13. If the clamping jaws 7 are subsequently moved towards one another in the clamping direction 9 and the clamping device 5 is thus brought into its clamping configuration, the cable 7 is clamped between the clamping jaws 7 and thus held relative to the clamping device 5.
  • the clamping device 1 has a holding device 15. This is designed to reliably hold a component 17, for example in the form of a sleeve 19, which has been pushed onto the cable 3 in the axial direction 21 and which at least partially surrounds the cable 3, in a desired position relative to the cable 3 during an assembly process by means of a force fit and/or a form fit.
  • the holding device 15 has two pressing elements 23.
  • each of the pressing elements 23 can press elastically transversely to the longitudinal direction 11 and thus essentially parallel to the clamping direction 9 against a side surface 25 of the sleeve 19.
  • the side surface 25 corresponds to an external surface of the cylindrical sleeve 19.
  • the two pressing elements 23 are arranged and aligned in such a way that they press against the sleeve 19 from opposite sides. Accordingly, the holding device 15 can fix the sleeve 19 in a centered manner.
  • the pressing element is designed with an elastically deformable spring component 27 in the form of a bent spring plate 29.
  • the spring plate 29 is attached with one end 31 to an associated clamping jaw 7.
  • the spring plate 29 is secured to the clamping jaw 7 by means of two Fastening screws 55 firmly and securely fix it to the clamping jaw 7.
  • the spring plate 29 is bent in such a way that a partial area 33 is formed at an end opposite the fixed end 31, which is directed towards the cable receiving volume 13 and projects into this volume between the opposing clamping jaws 7.
  • the spring plate 29 is given elastically deformable properties by means of which the partial area 33 of the spring plate 29 can bring about the desired elastic holding force for holding the separate component 17.
  • a gap 57 is formed between the partial area 33 of the spring plate 29 and an adjacent area of the clamping jaw 7.
  • the spring plate 29 When a force is applied to the partial area 33 in a direction opposite to the clamping direction 9, as is the case, for example, when the sleeve 19 is pushed axially into the holding device 15, the spring plate 29 can deform and the partial area 33 of the spring plate 29 can be moved away from the cable 3 and the sleeve 19 pushed onto it. Due to the deformation generated in this way, the spring plate 29 then brings about the desired mechanical pre-tension in order to generate the frictional connection required to hold the sleeve 19.
  • FIG 2 illustrates how the clamping device 1 is held on an overall clamping arrangement 47.
  • Each of the clamping jaws 7 is fixed to an associated holding block 59 by a screw connection.
  • the clamping jaws 7 can be automatically moved in and against the clamping direction 9 using an actuator 45.

  • the cable 3 can then be released again by the actuator 45 moving the clamping jaws 7 apart and thus returning the clamping device 5 to its release configuration.
  • Figure 3 illustrates an alternative second embodiment of a clamping device 1.
  • the spring component 27 is provided with two spring clips 35
  • the spring clips 35 are formed using bent, elastically deformable wires.
  • the two spring clips 35 are each attached to one of the clamping jaws 7 with both ends 37, for example by casting or gluing the respective ends 37 into a material of the clamping jaws 7.

  • the partial areas 39 of adjacent spring clips 35 extend parallel to one another and parallel to the longitudinal direction 11 of the cable 3.
  • the spring clips 35 can clamp the sleeve 19 from opposite sides by resting against its side surface 25 with mechanical preload. Since two spring clips 35 protrude towards the sleeve 19 on each of the clamping jaws 7, the sleeve 19 can be supported with its outer surface in four positions by the various spring clips 35 and thus held precisely centered. Due to the elongated and preferably linear partial area 39 of each of the spring clips 35, the sleeve 19 can also be held in a desired orientation, that is to say preferably in an orientation which corresponds to the longitudinal extension direction 11 of the cable 3.
