Abstract

A component has a base bushing, which has a first axial end and an opposite second axial end and a first inner diameter, wherein the base bushing is equipped with a first internal thread with a first thread direction, and has a fastening bushing, which has a third axial end and an opposite fourth axial end and a second inner diameter. The fastening bushing is equipped with a second internal thread with a second thread direction which is opposite to the first thread direction, wherein the second inner diameter is smaller than the first inner diameter and the base bushing and the fastening bushing are separate elements and are arranged coaxially with respect to one another in the component. Alternatively, the base bushing and the fastening bushing are formed as a single piece.

First claim

The invention claimed is:

1. A component with:
a. a base bushing including a first axial end and an opposite second axial end as well as a first inner diameter, with the base bushing being provided with a first inner thread of a first thread direction, and
b. a fastening bushing including a third axial end and an opposite fourth axial end as well as a second inner diameter, with the fastening bushing being provided with a second inner thread of a second thread direction that is opposite to the first thread direction, with
c. the second inner diameter being smaller than the first inner diameter and
d. the base bushing and the fastening bushing being separate elements and being arranged coaxially to each other in the component.

2. The component according to claim 1 , in which the base bushing and/or fastening bushing include at least one, preferably completely circumferential, profiling at a radial outer side, in particular in form of a knurling or in form of rips.

3. The component according to claim 1 , in which the base bushing is arranged adjacent to a surface of the component with its first axial end, in particular flush with the component surface.

4. The component according to claim 3 , in which the third axial end of the fastening bushing is arranged adjacent to the second axial end of the base bushing and the fourth axial end of the fastening bushing preferably comprises a bottom, so that the fourth axial end is preferably closed and an opening of the fastening bushing is present only at the third axial end.

5. The component according to claim 1 , with an adjusting element having a dragging element being arranged in the base bushing, the adjusting element including an outer thread matching the first inner thread of the base bushing, so that an automatic tolerance compensation of the distance to a second component is realizable.

6. The component according to claim 5 , in which the base bushing comprises a first securing means and the adjusting element comprises a second securing means, with the first and the second securing means interacting with each other, particularly in the completely screwed-in state of the adjusting element, thus forming a transport and/or counter locking.

7. The component according to claim 5 , in which the adjusting element consists of metal and/or the dragging element consists at least partially of plastic material, and/or with the material of the component comprising metal or plastic material.

8. A connection between a first component and a second component with a distance in between, with the first component being a component according to claim 5 , and a head of a fastening screw is arranged adjacent to a surface of the second component which faces away from the first component, with an outer thread of the screw engaging with the second inner thread of the fastening bushing.

9. A Setting system for manufacturing a component according to claim 1 , including:
a. a first positioning means comprising a first outer diameter which matches an inner diameter of a base bushing, so that the base bushing, which comprises a first inner thread of a first thread direction, is positionable on the first positioning means, and
b. a second positioning means comprising a second outer diameter which matches an inner diameter of the fastening bushing, so that the second outer diameter is smaller than the first outer diameter and the fastening bushing, which comprises a second inner thread of a second thread direction opposite to the first thread direction is positionable on the second positioning means, as well as
c. a first plasticizing means, which directly or indirectly provides for a plasticizing of the component before and/or during an inserting of the base bushing and/or the fastening bushing into the component, and
d. a first moving means with which the first positioning means and/or the second positioning means is movable, in particular along only one axis, and the base bushing and/or the fastening bushing are insertable into the component.

10. The setting system according to claim 9 , in which the first plasticizing means operates with one of the following: electric field, magnetic field, ultrasonic, oscillations, thermal radiation or a combination thereof, and/or in which the first plasticizing means provides for a heating of the base bushing and which comprises a second plasticizing means which provides for a heating of the fastening bushing.

11. The setting system according to claim 9 , in which the first and the second positioning means are arranged at a common setting head axially behind or downstream one another.

12. The setting system according to claim 11 , in which the first and the second positioning means have an unchangeable position with respect to one another and are movable jointly by means of the first moving means or
in which the setting system includes a second moving means, with the first positioning means being moveable by means of the first moving means and the second positioning means by means of the second moving means, so that the first and the second positioning means are moveable relatively to one another.

13. The setting system according to claim 9 , in which the first and the second positioning means are arranged next to one another at a common setting head, or in which the first and the second positioning means are each arranged at a setting head.

14. The setting system according to claim 9 , in which the base bushing is receivable on the first positioning means in a way sealed to the outside, so that in case of a later inserting, no component material can enter into the base bushing.

15. The setting system according to claim 14 , in which the fastening bushing is receivable on the second positioning means in a way sealed to the outside, so that in case of a later inserting, no component material can enter into the fastening bushing at least over the third axial end.

16. The setting system according to claim 9 , in which the base bushing and/or the fastening bushing are correspondingly held on the first and/or the second positioning means by means of: friction locking, in particular by means of a spring, negative pressure, adhesive, magnets or a suitable outer thread of the first and/or the second positioning means or a combination thereof.

17. The setting system according to claim 9 , which furthermore includes a first detecting means for detecting an equipment of the first and/or the second positioning means with the base bushing and/or the fastening bushing.

18. The setting system according to claim 9 , which furthermore includes a second detecting means for detecting a setting depth of the base bushing and/or fastening bushing into the component and/or with the first and/or the second moving means being a pneumatic cylinder.

19. A manufacturing method for a component according to claim 1 , including the steps:
a1. providing the component as well as a base bushing and a fastening bushing, or
a2. providing the component with fastening bushing molded therein and a separate base bushing
a3. inserting the fastening bushing and/or the base bushing into the component, so that the fastening bushing and the base bushing are arranged coaxially to one another in the component,
wherein a setting system is used for at least part of the steps, the setting system comprising: a first positioning means comprising a first outer diameter which matches an inner diameter of a base bushing, so that the base bushing, which comprises a first inner thread of a first thread direction, is positionable on the fi
