Abstract

An apparatus of a setting welding device for an auxiliary joining part with a head and a shaft, includes a linear drive fastenable at the setting device and including an element nest at a movable end, in which an auxiliary joining part is releasably receivable from a transfer unit. The element nest is movable by the linear drive in a first direction. The element nest is supported in a floating manner, and is positionable via a mechanical stop alignment in abutment with an electrode punch in the joining direction below the electrode punch. And/or the element nest is connected with the linear drive via a mechanical direction-changing coupling component so that the element nest is movable by the linear drive in a second direction so that the auxiliary joining part is positionable at the joining location, wherein the second direction is not parallel to the first direction.

First claim

The invention claimed is:

1. An element nest of a welding auxiliary joining part with a head and a shaft, wherein the element nest is configured for use in a setting welding device having an electrode punch, wherein
the element nest comprises two element jaws that are arranged opposite to each other and spring relative to each other, with which the welding auxiliary joining part is releasably holdable and which are supported in a floating manner in a plane perpendicular to a joining direction of the setting welding device,
as a mechanical stop alignment, the element nest comprises a contour piece with an abutment contour face that is adapted to an outer shape of the electrode punch, and
the element jaws of the element nest are laterally fastened at the contour piece in a springy manner and the contour piece is arranged in a springingly, deflectable manner in at least two directions within a plane perpendicularly to the joining direction, wherein
the element nest is supported in a plane approximately perpendicular to the joining direction of the setting welding device in a floating manner, in order to be positionable via the mechanical stop alignment in abutment with the electrode punch of the setting welding device in the joining direction below the electrode punch.

2. A setting welding device for a welding auxiliary joining part with a head and a shaft in combination with an element nest according to claim 1 .

3. A retrofit kit comprising an element nest according to claim 1 which is connectable with a setting welding device.
