    Embodiments relate to a system for machining a component and to the component and a clamping element for the system.
    In a variety of different machining processes, such as turning, milling or grinding, components in a chuck, for example by means of jaws, clamped. An axial securing of the component is usually done by friction.
    One of these applications is, for example, the turning of plastic or plastic semi-finished products. For this purpose, the semi-finished product or the plastic component, which is to be worked on, is fixed by clamping jaws in a jaw chuck. Depending on a diameter of the semi-finished product may have to be used different jaw sizes. The semifinished product or the component to be machined is then held only by friction between a semifinished product outside and a clamping jaw contour. As a result, high clamping forces are required. Under unfavorable circumstances, it can happen that the semi-finished product or the component to be machined is deformed. In order to prevent deformation, usually a high number of jaw sets, for example, more than fifteen, possibly even eighteen sets used. Each set is matched to a specific diameter range. As a result, almost the entire circumference of the semifinished product can then be enclosed with the matching clothing. The provision of so many different jaw sets may be very material and space intensive.
    There is therefore a need to provide an improved concept for machining. This need is taken into account by the system, the component and the clamping element according to the independent claims.
    Embodiments relate to a system for machining a component. The system comprises for this purpose the component with a base body made of plastic. The component also includes a tensioning aid structure. Furthermore, the system includes a tensioning element configured to tension the component. The clamping element comprises at least one clamping jaw with at least one counter-clamping auxiliary structure. The counter-clamping auxiliary structure is designed to be in engagement with the clamping auxiliary structure and to fix the component in the axial direction in a form-fitting manner with respect to the clamping element. In some embodiments, the fact that there is a form fit in the axial direction, compared to variants in which the axial securing is achieved via a frictional engagement, a smaller number of clamping jaws and / or a lower clamping force can be used. In some embodiments, thereby a deformation of the component can be at least reduced or even completely prevented.
    The component may be any of a variety of components that may be suitable for machining, such as a lathe, a grinding, or the like, for example, a bullet, a pipe, such as a circular cross-section, a cylinder, such as a cylinder a circular, a triangular, a triangular or another cross-section, a cone or the like. Additionally or alternatively, the base body may have one of the forms described.
    As plastics, it is possible to use all sorts of plastics, for example polyethylene (PE), HD-PE (high-density PE), LLD-PE (linear-low-density PE), LD-PE (low-density PE), polypropylene ( PP), polyvinyl chloride (PVC), polystyrene (PS), polyurethane (PU / PUR), polyethylene terephthalate (PET) or the like.
    For example, the tension member may be any component that is configured to hold a component for machining, such as for turning. In other words, the clamping element can be designed to arrange the component so that it can be rotated about its own longitudinal or rotational axis. For this purpose, the clamping element may have at least one clamping jaw, but also two or three clamping jaws.
    The clamping auxiliary structure and the counter-clamping auxiliary structure, which engage with one another in order to fix the component in the axial direction in a form-fitting manner and via a clamping element, can be any structures on the component and the clamping jaw which, in combination with each other, form a positive fit in the axial direction enable. For example, the tensioning structure may be a recess and, correspondingly, the counter-tensioning aid structure may be a projection, a hook, or an elevation that engages the recess. A fixing in the axial direction may be present, for example, when a relative movement of the component relative to the clamping element in the axial direction is prevented. Since component can also be fixed in the circumferential direction and / or in the radial direction in the clamping element, for example frictionally and / or positively.
    Additionally or alternatively, the auxiliary clamping structure may have a larger diameter and / or a smaller diameter than a directly adjacent surface of the component in the axial direction. In some embodiments, the positive connection with the counter-clamping auxiliary structure can thus be achieved in a simple manner. For example, the counter-clamping auxiliary structure can be designed as a corresponding male counterpart to a female clamping auxiliary structure. Optionally, the counter-clamping auxiliary structure can also be designed as a corresponding female counterpart to a male tension auxiliary structure. By way of example, the auxiliary clamping structure may be a groove or groove or recess which completely revolves in the circumferential direction. The recess can have any cross-sectional shape, for example rectangular, triangular, square, round or oval. Accordingly, the counter-clamping auxiliary structure may have the same or similar cross-section. Under certain circumstances, the counter-clamping auxiliary structure in the axial direction may have a smaller extent than the auxiliary clamping structure, if this has the increase. Alternatively, the clamping auxiliary structure in the axial direction may have a smaller extent than the counter-clamping auxiliary structure if the auxiliary clamping structure has the elevation relative to the surrounding surface. In some embodiments, the tension assist structure may have at least one stop in the axial direction or also two stops in the axial direction. Analogously, the counter-clamping auxiliary structure can have exactly one or at least one stop in the axial direction or even two such stops.
    The counter-clamping auxiliary structure can be arranged, for example, on a radially inwardly directed surface of the clamping jaw. In embodiments in which a clamping surface of the clamping jaw, which is in contact with the component, is directed radially inward, a positive connection can thus be achieved in the axial direction. In the circumferential direction, the counter-clamping auxiliary structure can extend completely along an extension of the clamping surface of the clamping jaw. Alternatively, the counter-clamping auxiliary structure in the circumferential direction have a smaller extent than the clamping jaw or its radially inwardly directed surface in the circumferential direction, for example at most 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80% or 90%. In the axial direction, the counter-clamping auxiliary structure can be arranged on an edge of the clamping surface, for example on an edge facing away from the chuck or on an edge facing the chuck. Alternatively, the clamping auxiliary structure can also be arranged at a distance from the edges of the clamping jaw. Optionally, the component can also be designed so that its radially inwardly directed surface is in contact with at least one radially outwardly directed clamping surface of a clamping jaw of a clamping element.
    Additionally or alternatively, the auxiliary clamping structure can be arranged in the circumferential direction at least overlapping the at least one clamping jaw. In some embodiments, it may thereby be possible for the at least one clamping jaw, which has the counter-clamping auxiliary structure, to be able to engage with the clamping auxiliary structure. In some embodiments, the
    Spannhilfsstruktur only in a region which overlaps in the circumferential direction with the clamping jaw, be arranged. For example, the auxiliary clamping structure, which is arranged in overlapping relation to a clamping jaw, can have the same or a greater extent in the circumferential direction than the clamping jaw, for example by more than 5%, 10% or 20%.
    Additionally or alternatively, the clamping auxiliary structure can be arranged completely circumferentially in the circumferential direction. In some embodiments, thereby arranging the clamping jaws or the chuck can be simplified.
    Additionally or alternatively, the clamping element may have exactly three clamping jaws. In some embodiments, this allows a geometrically determined fixation of the component in the clamping element. The three clamping jaws can be arranged, for example, each at an angular distance of 120 °. Additionally or alternatively, the three clamping jaws can also be arranged at the same axial height. In some embodiments, the clamping element may also have a higher number of clamping jaws, for example, a maximum of four, five, six, seven, eight or ten.
    Additionally or alternatively, the base body may be a cylinder, a hollow cylinder, for example a circular cylinder, a circular hollow cylinder, a cone, for example a circular cone, a circular hollow cone or a truncated cone. In some embodiments, it may be achieved that the component is already close to a shape of a final product to be produced during turning. The product may be any end product, such as a gasket, an O-ring, a bearing bush, a spacer, or the like.
    Additionally or alternatively, the component may comprise an adapter. The adapter may for example be connected to the base body and have a larger outer diameter than the main body. The tension auxiliary structure can be arranged, for example, on the adapter. In some embodiments, thereby components with a smaller outer diameter can be clamped with the clamping element. The adapter may be, for example, an annular component. An inner diameter of the adapter may for example be the same or similar to an outer diameter of the base body. Under certain circumstances, the adapter may have a different material than the main body. Eventually, the adapter and the base body may be welded together. Additionally or alternatively, the clamping auxiliary structure may be arranged, for example, in the axial direction overlapping the adapter. In other words, the adapter may comprise the tension assist structure. Under certain circumstances, the clamping auxiliary structure can be arranged close to an end edge of the adapter, for example on an end edge which faces away from the clamping element in a clamped state. For example, the tension assist structure can be spaced from the end edge by a maximum of 10%, 5%, 2%, 3% or 1% of an axial extent of the adapter. The adapter may be arranged in the axial direction, for example, overlapping the base body. An axial extent of the adapter can correspond to a maximum of 20%, 10%, 5% or 2% of an axial extent of the base body and / or at least 1%, 2%, 3%, 4% or 5% of an axial extent of the base body.
    Alternatively, the clamping auxiliary structure can also be arranged directly on the base body. This may for example be the case in embodiments in which the component has no adapter.
    Additionally or alternatively, the auxiliary clamping structure in the axial direction may have an extension that is less than 10%, 5%, 3%, 2% or 1% and / or greater than 0.5%, 1%, 2% or 3% an axial extension of the component. Additionally or alternatively, the counter-tensioning auxiliary structure in the axial direction may have an extension which is less than 10%, 5%, 3%, 2% or 1% and / or greater than 0.5%, 1%, 2% or 3%. an axial extension of the component. In some embodiments, this may allow the auxiliary clamping structure and / or the counter-tensioning auxiliary structure to occupy only little space and still be able to perform their function. For example, the stated expansions may each be an unprocessed state of the component. In a finished state of the component, for example, the auxiliary clamping structure and / or the adapter may have been separated from the end product.
    Additionally or alternatively, the Spannhilfsstruktur and / or the adapter can be arranged at an axial height of the component which corresponds to a maximum of 20%, 10%, 8%, 7%, 6% or 5% of an axial extent of the component. In some embodiments, this can be made possible by the fact that the component is clamped to an edge. For example, while the shorter part of the component, which is separated by the Spannhilfsstruktur from the longer part of the component, be included in the chuck.
    Embodiments also relate to a component that is designed to be machined. The component comprises a main body made of a plastic which is a circular cylinder, a circular hollow cylinder, a circular cone or a circular hollow cone or a truncated cone. Furthermore, the component comprises at least one tensioning aid. The tensioning aid is at least one elevation and / or one depression with respect to a surface of the component which is adjacent in the axial direction. In some embodiments, this may allow the component to be used in the system according to one of the preceding embodiments.
    Embodiments also relate to a clamping element which is designed to form-fit a component for machining in the axial direction. For this purpose, the clamping element comprises at least and / or three clamping jaws, wherein at least one clamping jaw comprises at least one counter-clamping auxiliary structure. The counter-clamping auxiliary structure has at least one elevation and / or at least one depression with respect to an axially adjacent surface of the clamping jaw. This may be, for example, the radially inwardly directed surface of the clamping jaw. In some embodiments, this tensioning aid can be used in the previously described system.
    The embodiments disclosed in the foregoing description, the appended claims and the appended figures, as well as their individual features, may be relevant and implemented both individually and in any combination for the realization of an embodiment in its various forms. Thus, the figures show schematically the following views.
    Fig. 1 shows a schematic representation of a perspective view of a system with the component and the clamping element according to an embodiment;
    Fig. 2 shows a schematic representation of an enlarged detail of Fig. 1;
    Fig. 3 shows a schematic representation of a sectional view through a clamping element according to an embodiment.
    In the following description of the accompanying drawings, like reference characters designate like or similar components. Further, summary reference numbers are used for components and objects that occur multiple times in one embodiment or in one representation, but are described together in terms of one or more features. Components or objects which are described by the same or by the same reference numerals may be the same, but possibly also different, in terms of individual, several or all features, for example their dimensions, unless otherwise explicitly or implicitly stated in the description.
    1 shows a schematic representation of a perspective view of a system 1 for machining a component 2. The system 1 comprises the component 2 for this purpose. The component 2 comprises a main body 3 and at least one
    Spannhilfsstruktur 4. The main body 3 has as a plastic material. Furthermore, the system 1 comprises a clamping element 5, which is designed to tension the component 2. The clamping element 5 has at least one clamping jaw 6. The clamping jaw 6 has at least one counter-clamping auxiliary structure 7. The counter-clamping auxiliary structure 7 is designed to be in engagement with the auxiliary clamping structure 4, so that the component 2 is fixed in the axial direction M in a form-fitting manner with respect to the clamping element 5 and / or positioned.
    The component 2 is a semi-finished product made of a plastic. For example, this can be machined to produce a seal. The main body 3 of the component 2 is a circular hollow cylinder. The further details will be described with reference to the enlarged view in FIG. 2.
    On the main body 3, an adapter 8 is attached. In the adapter 8 is a plastic ring having an inner diameter which corresponds approximately to an outer diameter of the base body 3. An outer diameter of the adapter 8 is larger than the outer diameter of the main body 3. For example, the adapter 8 may have a different material than the main body 3, but possibly also a plastic. The adapter 8 may for example be welded to the base body 3. Task of the adapter 8 may be, for example, to increase a diameter of the Grundköpers 3, so that it can be better tensioned in the clamping element 5. The adapter 8 also comprises the auxiliary clamping structure 4. In some other embodiments, not shown, the tensioning aid structure can also be arranged directly on the base body. In these cases, the adapter can be omitted or still be present.
    3 shows a schematic representation of a cross section through the adapter 8. In the cross section and the auxiliary clamping structure 4 can be seen. When the auxiliary clamping structure 4 is a depression relative to a surface 9 of the adapter 8. This results in a paragraph with a ge in the axial direction directed end face 10. The Spannhilfsstruktur 9 is therefore formed in this case as a recess. The counter-clamping auxiliary structure 7 on the clamping jaw 6 is in contrast formed as a radial projection, which rests in the axial direction on the end face 10.
    As can be seen in FIG. 2, the counter-clamping auxiliary structure 7 is not formed completely along the circumferential direction U on the clamping jaw 6, but is interrupted by an arcuate recess 11. This results in a Gegenspannhilfsstruktur 7-a and a Gegenspannhilfsstruktur 7-b respectively at circumferentially U directed ends of the clamping jaw 6. A radial extent of the counter-clamping auxiliary structure 7-a can, for example, at least 1%, 2%, 3%, 4%, 5 % or 10% of an outer diameter of the component 2 and / or at most 10%, 9% or 8%.
    In other words, in the exemplary embodiment of the figures, a single clamping jaw 6 has two counter-clamping auxiliary structures 7-a and 7-b, which are spaced apart in the circumferential direction U. In some other embodiments, not shown, each jaw may also have only one counter-clamping auxiliary structure.
    An axially adjacent clamping portion 11 of the clamping jaw 6 and its radially inwardly directed surface is located in the radial direction on the surface 9 of the adapter 8 at. In some other embodiments, not shown, this surface may also be spaced from the adapter. The counter-clamping auxiliary structure 7 projects radially further in the radial direction than the clamping section 11.
    Overall, the clamping element 5 comprises two further clamping jaws, namely the recognizable in Fig. 1 jaw 6-a and another, not shown jaw. The three jaws are each arranged at an angle of 120 ° in the circumferential direction spaced from each other. In some other, not shown
    Embodiments may also be provided a different number of clamping jaws.
    In other words, in some embodiments it may be a positive clamping system for plastic semi-finished products on CNC lathes or other lathes. The attachment of the component, which can also be referred to as semi-finished, can be done by a positive engagement and not by friction as in conventional clamping systems. As a result, in some embodiments, clamping forces can be reduced and the deformation of the component or of the semifinished plastic product is at least reduced or completely avoided.
    Compared to conventional clamping systems in which for diameters ranges from 30 to 400 mm often up to 18 jaws must be used, in some embodiments, a jaw, each with three identical jaws a variety of diameters, for example, greater than 30 mm, 40 mm, 50 mm , 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, 120 mm, 130 mm, 140 mm, 150 mm, 200 mm, 250 mm, 300 mm or 350 mm and less than 400 mm, 450 mm or 300 mm ,
    The clamping jaws 6 may be equipped, for example, with a hook as a counter-tensioning auxiliary structure 7, which engages in a corresponding groove which serves in the component 2 or the semifinished product as a clamping auxiliary structure. The dimensions of the hook of the clamping jaw 7 and the groove in the component 2 are matched to one another, so that a positive fixing can be made possible. The production of the groove or depression in the semifinished product does not represent an increased expense in some embodiments. For clamping the semifinished product 2, for example, three clamping jaws 6 can be moved inwards. The component 2 can thereby be clamped.
    In some embodiments, instead of the eighteen jaws now two clamping jaws easily manufactured, each comprising three clamping jaws, can be used with the counter-clamping auxiliary structures. As a result, in some embodiments, the cost of clamping devices may decrease because a smaller number of clamping jaw sets is needed. The tensioner may eventually be used for a wider range of diameters. The component can be clamped more securely because it is positively clamped in the axial direction and not only by rubbing. Eventually, in some embodiments, costs may decrease in a running operation because the time for a jaw change is reduced. Further, possibly an additional customer loyalty can be achieved because the jaws can be used in some embodiments only with the corresponding components or semi-finished products. The tensioning element may be, for example, a three-jaw hand-held chuck.
    The system or the clamping element and the component can be used not only as described for the figures, for the production of seals from a plastic semi-finished product, but also for the production of all possible components that can be made of plastic in a turning process, for example cages, Bearing disks, sliding washers, spacers or the like.
    The embodiments disclosed in the foregoing description, the appended claims and the appended figures, as well as their individual features, may be relevant and implemented both individually and in any combination for the realization of an embodiment in its various forms.
