Background Art

[0002] The additive production of components constitutes a groundbreaking manufacturing technology which has been growing in importance over the past decade. Plastic components can be produced here using various techniques, for example by selective laser sintering (SLS). Since these components can be produced as integral or one-piece parts in comparison with corresponding conventional components which are configured as subassemblies comprising a plurality of interconnected components, a significant reduction in costs and a reduction in assembly time are associated with additively produced components.

[0003] An example of such an additionally produced component is a production aid, with which a component can be positioned relative to another component during production (e.g., the production of a vehicle). Given its correct arrangement on the other component, the production aid predefines the correct positioning of the component relative to the other component, so that the connection of the respective component to the other component in series production can be ensured with constant quality.

Summary of the invention

[0010] The object of the invention is to improve a production aid of the type mentioned in the introduction in such a way that it can be individually adapted to the respective structural conditions in a simple manner.

[0011] According to the present invention, this object is achieved by a production aid having the following characteristics, wherein at least one opening is configured on the positioning body, in which there is a rigidly fitted spacer bushing, the spacer bushing having a through hole or a positioning pivot configured integrally with the spacer bushing, the positioning pin being guided through the through hole, wherein the positioning body contacts another component via the positioning pin or the positioning pivot, wherein the longitudinal center axis of the through hole is arranged to be parallel and offset from the longitudinal center axis of the spacer bushing.

[0012] It should be pointed out that those features and measures cited individually in the following description can be combined with one another in any optional technically reasonable manner and present further embodiments of the invention. The additional features of this description particularly illustrate the invention in conjunction with the drawings.

[0013] According to the invention, the positioning pin or positioning pivot inserted into the through hole of the spacing bushing can be arranged in various positions relative to the part of the integral positioning body comprising the opening, wherein the longitudinal center axis of the spacing bushing is arranged in various rotational positions relative to the part. As a result, the production auxiliary device can be adapted in a simple manner to the corresponding geometric or structural conditions, in particular to the other component, so that, for example, in the case of dimensional differences between the components, the component attached to the other component can be positioned in a correct manner relative to the other component and attached thereto. Pre-measured dimensional differences can be compensated or eliminated here.

[0014] The positioning body may also be provided with two or more corresponding openings, in which rigidly fitted dedicated spacing bushings are respectively located, the spacing bushings having a through hole or being configured as a positioning pivot integrally with the spacing bushing, through which a dedicated positioning pin is guided, wherein the positioning body is in contact with another component via the positioning pin or the positioning pivot, wherein the longitudinal center axis of the through hole is arranged parallel and offset from the longitudinal center axis of the spacing bushing. For example, a manually operable production aid may be in contact with another component only via one or more positioning pins or one or more positioning pivots, and may be arranged at a distance from the other component.

[0015] The component to be attached to the other component can be connected to the other component, for example, rigidly or non-rigidly, after a correct positioning relative to the other component. The other component can be a body part of a motor vehicle, to which the component is to be attached. For this purpose, the production aid is first arranged on the other component, so that the production aid, due to its structural design and in view of its correct arrangement of the other component, predefines a corresponding correct positioning of the component relative to the other component. Afterwards, the component is not yet connected to the other component.

[0016] The positioning body is integral in the sense that the positioning body is not formed by two or more separately manufactured parts, but is formed as one piece during the manufacturing process. The positioning body can be configured as a hollow body or solidly constructed. The positioning body can have a complex geometric shape that is suitable for the corresponding purpose of use or the shape of the corresponding other component and the shape of the component connected thereto.

[0017] According to an advantageous embodiment, the positioning body is additively manufactured. As a result, the positioning body can also be manufactured in a simple and cost-effective manner with very complex geometries. In contrast to conventional production aids formed from a plurality of interconnected components, no subsequent processing steps, such as milling or the like, are required. The positioning body can be manufactured, for example, by a 3D printing process or an SLS process. In particular, the positioning body can be made of plastic.

[0018] Another advantageous embodiment provides that the outer peripheral surface of the spacing bushing and the inner peripheral surface of the portion of the positioning body in contact therewith, including the opening, are respectively configured as a hollow cylinder with a circular or polygonal base area. Both embodiments enable various relative positions of the spacing bushing to the portion of the positioning body having the opening. If the outer peripheral surface of the spacing bushing and the inner peripheral surface of the portion including the opening are respectively configured as a hollow cylinder with a circular base area, the spacing bushing can be arranged at any selected number of different relative positions to the portion. If the outer peripheral surface of the spacing bushing and the inner peripheral surface of the portion including the opening are respectively configured as a hollow cylinder with a polygonal base area, the spacing bushing can be arranged at a limited number of different discrete relative positions to the portion. For example, the polygonal base area can be configured as an equilateral triangle, a square or other regular polygon, and thus as an equilateral and equiangular polygon.

[0019] According to a further advantageous embodiment, at least one mark is arranged on the axial end face of the spacer bushing, which mark indicates the direction in which the longitudinal center axis of the through hole is arranged parallel to the longitudinal center axis of the spacer bushing. As a result, the user of the production aid can visually detect whether the spacer bushing is arranged in a manner relative to that part of the positioning body, which part includes an opening that is intentionally adapted to the production aid at least to another component, for example in order to compensate for size differences. For example, the mark can be arranged on that side of the through hole that has the shortest radial distance to the outer peripheral surface of the spacer bushing. The mark can be configured as a color and / or physical mark.

[0020] Advantageously, at least one marking is arranged on the positioning body adjacent to the portion comprising the opening. The outer peripheral surface of the spacing bushing and the inner peripheral surface of the portion comprising the opening are respectively configured as hollow cylinders with circular base areas and the marking is arranged on the spacing bushing, which is particularly advantageous because the marking on the spacing bushing can be oriented to adjust the parallel offset between the longitudinal center axis of the through hole and the spacing bushing relative to the marking on the positioning body. The marking on the positioning body can be configured as a single marking or a scale on which various orientations of the spacing bushing relative to the portion are readable and therefore adjustable. Alternatively, the marking on the positioning body can be configured as a single marking and the marking on the spacing bushing is a scale.

[0021] According to a further advantageous embodiment, the production aid comprises at least two differently configured spacer bushings which can be selectively fitted into the openings and which differ from one another in the distance of the longitudinal center axis of the respective through hole from the longitudinal center axis of the respective spacer bushing. The various spacer bushings can be standardized, for example a 0.1 mm offset bushing, a 0.2 mm offset bushing, etc., and can be reused. By selecting the respective spacer bushing and inserting it into the opening on the positioning body, the production aid can be adapted to the respective application in a simple manner. The outer shape of the spacer bushings is preferably identical.

[0022] Another advantageous embodiment provides that the spacer bushing is manufactured using an additive production process or an injection molding process. Thus, the spacer bushing, in particular a plastic bushing, can be manufactured in a simple and cost-effective manner. The spacer bushing can be manufactured additively together with the positioning pivot.

[0023] According to a further advantageous embodiment, at least two corresponding openings are provided on the positioning body, the longitudinal center axes of the openings being oriented non-parallel to one another and in each of the openings there is a rigidly fitting dedicated spacing bushing, which has a through hole through which a dedicated positioning pin is guided, via which the positioning body is in contact with the other component, wherein the longitudinal center axis of the through hole is arranged parallel to the longitudinal center axis of the spacing bushing. As a result, the production aid can be adapted three-dimensionally to the respective application. BRIEF DESCRIPTION OF THE DRAWINGS
