Abstract

A riveting device for the riveting of components in an overlap joint, with an upper tool for driving a rivet into a rivet hole passing through the components, and with a lower tool as a dolly, which has a deforming section for purposes of plastically deforming the end of a rivet shaft driven through the rivet hole, wherein the riveting device has a magazine with a feed device for purposes of feeding a rivet into a shot passage of the upper tool, an actuator for purposes of accelerating the rivet introduced into the shot passage of the upper tool in the direction of the components, and an adjustment system for purposes of aligning the shot channel with the rivet hole. Also disclosed is a method for the riveting of components in an overlap joint.

First claim

The invention claimed is:

1. A riveting device for the connection of components in an overlap joint, comprising:
an upper tool for driving a rivet into a rivet hole passing through the components, and
a lower tool as a dolly, which has a deforming section for purposes of plastically deforming the end of a rivet shaft driven through the rivet hole,
the riveting device having a magazine with a feed device for purposes of feeding a rivet into a shot passage of the upper tool, an actuator for purposes of accelerating the rivet introduced into the shot passage in the direction of the components, and an adjustment system for purposes of aligning the shot passage with the rivet hole.

2. The riveting device according to claim 1 , wherein the actuator is configured to generate an electromagnetic acceleration force acting on the rivet.

3. The riveting device according to claim 1 , wherein in the shot passage an electromagnetically movable hammer element is arranged which acts on the rivet.

4. The riveting device according to claim 1 , wherein the actuator has at least two coils that communicate with each other, of which one coil is arranged in the lower tool and the other coil is arranged in the upper tool.

5. The riveting device according to claim 1 , wherein the adjustment system comprises an electromagnetic radiation source for purposes of optically aligning the riveting device.

6. The riveting device according to claim 1 , wherein the lower tool comprises a multitude of deforming sections for covering a multitude of rivet holes.

7. The riveting device according to claim 1 , wherein the magazine has a sorting device for providing different types of rivets.

8. The riveting device according to claim 1 , wherein at least one of the upper tool and the lower tool, at least in some sections, comprises a housing made of a sound-absorbent material.

9. The riveting device according to claim 1 , wherein at least one of the upper tool and the lower tool is associated with at least one noise cancelling device for at least partial superposition of a riveting noise by an anti-noise.

10. A riveting method for the connection of components in an overlap joint with a riveting device by means of which a rivet is driven into a rivet hole passing through the components, the riveting device comprising:
an upper tool for driving a rivet into a rivet hole passing through the components, and
a lower tool as a dolly, which has a deforming section for purposes of plastically deforming the end of a rivet shaft driven through the rivet hole,
the riveting device having a magazine with a feed device for purposes of feeding a rivet into a shot passage of the upper tool, an actuator for purposes of accelerating the rivet introduced into the shot passage in the direction of the components, and an adjustment system for purposes of aligning the shot passage with the rivet hole,
the riveting method comprising the steps:
positioning the riveting device relative to the rivet hole, wherein a lower tool of the riveting device is arranged as a dolly on one face of a component, and an upper tool of the riveting device for driving a rivet into the rivet hole is arranged on the opposite face of another component, and a shot passage in the upper tool is oriented so as to be aligned with the rivet hole,
feeding a rivet into the shot passage, and
accelerating the rivet in the direction of the components, wherein during driving a rivet in, an end of a rivet shaft driven through the rivet hole is plastically deformed when the end of the rivet shaft impacts a deforming section of the lower tool.

11. The riveting method according to claim 10 , wherein the rivet is electromagnetically accelerated.

12. The riveting method according to claim 11 , wherein an electromagnetic acceleration force applied on a side of the upper tool and on a side of the lower tool acts on the rivet.

13. The riveting method according to claim 10 , wherein an electromagnetically accelerated hammer element acts on the rivet.

14. The riveting method according to claim 10 , wherein the lower tool is associated with a rivet hole field.

15. The riveting method according to claim 10 , wherein at least partial overlay of a riveting noise with an anti-noise takes place.
