Abstract
A method for jointing elements, each having a cutout, on a shaft by a device for producing a control shaft, comprises disposing the elements vertically above one another, aligned, and fixed. The method also comprises pushing the shaft in vertically from above though the cutouts of the elements by a traversable guide carriage of the device and displacing by a pneumatic piston of the device the traversable guide carriage and the shaft attached thereto until a maximum first press-in force is reached. The method further comprises displacing by at least two spindles of an electric spindle drive of the device the traversable guide carriage and the shaft when the maximum first press-in force is exceeded.

A method for jointing elements, each comprising a cutout, on a shaft by a device, for producing a control shaft, comprising:
- traversing at least two spindles of an electrical spindle drive of the device into a predefined end position;
- disposing the elements vertically above one another, aligned, and fixed;
- pushing the shaft in vertically from above through the cutouts of the elements by a traversable guide carriage of the device;
- wherein pushing the shaft by the traversable guide carriage includes displacing by a pneumatic piston of the device the traversable guide carriage of the device and the shaft attached to the traversable guide carriage until a maximum first press-in force is reached;
- displacing, in a press-fit jointing operation, the traversable guide carriage and the shaft by the at least two spindles of the electric spindle drive of the device when the maximum first press-in force is exceeded;
- and
- wherein traversing the at least two spindles of the electrical spindle drive of the device into the predefined end position comprises traversing the at least two spindles of the electrical spindle drive of the device into the predefined end position in a thermal jointing operation.
A method for jointing elements, each comprising a cutout, on a shaft by a device, for producing a control shaft, comprising:
- penetrating a traversable guide carriage of the device with at least two spindles of an electrical spindle drive of the device;
- disposing the elements vertically above one another, aligned, and fixed;
- pushing the shaft in vertically from above through the cutouts of the elements by the traversable guide carriage of the device;
- wherein pushing the shaft by the traversable guide carriage includes displacing by a pneumatic piston of the device the traversable guide carriage of the device and the shaft attached to the traversable guide carriage until a maximum first press-in force is reached;
- displacing, in a press-fit jointing operation, the traversable guide carriage and the shaft by the at least two spindles of the electric spindle drive when the maximum first press-in force is exceeded;
- wherein displacing the traversable guide carriage and the shaft by the at least two spindles includes engaging respective spindle heads of the at least two spindles against corresponding stop contours of the traversable guide carriage disposed spaced apart from an underside of the traversable guide carriage, and pressing the traversable guide carriage via the stop contours further downwards for the press-fit jointing operation.
