Abstract

A device for jointing a plurality of elements, each comprising a cutout for a shaft, in a predetermined angular position on the shaft, may include a traversable guide carriage configured to push the shaft from above through the cutouts of the elements. The device may also include an electrical spindle drive and a pneumatic piston for displacing the traversable guide carriage.

First claim

The invention claimed is:

1. A device for jointing a plurality of elements, each having a cutout for a shaft, in a predetermined angular position on the shaft, comprising:
a traversable guide carriage configured to push the shaft from above through the cutouts of the elements; and
an electrical spindle drive and a pneumatic piston for displacing the traversable guide carriage,
wherein the pneumatic piston is configured to contact an upper side of the traversable guide carriage, and the electrical spindle drive is configured to penetrate the traversable guide carriage, and
wherein the traversable guide carriage includes stop contours spaced apart from an under side of the traversable guide carriage, the electrical spindle drive includes two spindles, and the two spindles are configured to rest on the stop contours.

2. The device according to claim 1 , wherein:
the pneumatic piston is configured to apply a maximum first press-in force on the traversable guide carriage;
the spindles penetrate the traversable guide carriage, and include respective spindle heads at the under side of the traversable guide carriage; and
the electrical spindle drive serves as an end stop for the traversable guide carriage.

3. The device according to claim 2 , further comprising at least two guide rods for guiding the traversable guide carriage, the guide rods running parallel to the two spindles and parallel to the pneumatic piston.

4. The device according to claim 3 , further comprising at least one cross member, wherein the guide rods are fixedly connected to the traversable guide carriage and guided vertically in a displaceable manner in the at least one cross member.

5. The device according to claim 2 , wherein the a stop contours are in a region of the spindle heads, and on which the respective spindle heads rest if a second press-in force exceeds the first press-in force.

6. The device according to claim 5 , wherein the stop contours are one of hook contours and pots.

7. The device according to claim 1 , wherein:
the pneumatic piston is configured to apply a maximum first press-in force;
the two spindles penetrate the traversable guide carriage, and include respective spindle heads at the under side of the traversable guide carriage; and
the stop contours are in regions of the spindle heads of the two spindles, and on which the respective spindle heads rest if a second press-in force exceeds the first press-in force.

8. The device according to claim 1 , wherein the stop contours are one of hook contours and pots.

9. The device according to claim 1 , further comprising a detector including a sensor configured to monitor an electrical contact and switch off the device if at least one of a maximum first press-in force is exceeded and if the traversable guide carriage does not reach an end position.

10. The device according to claim 9 , wherein the electrical contact is between the traversable guide carriage and at least one of the spindles of the electrical spindle drive.

11. The device according to claim 1 , further comprising at least two guide rods for guiding the traversable guide carriage, the guide rods running parallel to the spindles and parallel to the pneumatic piston.

12. The device according to claim 11 , further comprising at least one cross member, wherein the guide rods are fixedly connected to the traversable guide carriage and guided vertically in a displaceable manner in the at least one cross member.

13. A device for jointing a plurality of elements, each having a cutout for a shaft, in a predetermined angular position on the shaft, comprising:
a traversable guide carriage configured to push the shaft from above through the cutouts of the elements; and
an electrical spindle drive and a pneumatic piston for displacing the traversable guide carriage,
wherein the pneumatic piston is in contact with an upper side of the traversable guide carriage and is configured to apply a maximum first press-in force on the traversable guide carriage,
the electrical spindle drive includes at least two spindles, which penetrate the traversable guide carriage and which each has a spindle head at an underside of the traversable guide carriage, and
the electrical spindle drive serves as an end stop for the traversable guide carriage.

14. The device according to claim 13 , wherein the traversable guide carriage includes stop contours that are one of hook contours and pots.

15. The device according to claim 13 , further comprising a detector including a sensor configured to monitor an electrical contact and switch off the device if at least one of a maximum first press-in force is exceeded and if the traversable guide carriage does not reach an end position.

16. The device according to claim 15 , wherein the electrical contact is between the traversable guide carriage and at least one of the at least two spindles of the electrical spindle drive.

17. A device for jointing a plurality of elements, each having a cutout for a shaft, in a predetermined angular position on the shaft, comprising:
a traversable guide carriage configured to push the shaft from above through the cutouts of the elements; and
an electrical spindle drive and a pneumatic piston for displacing the traversable guide carriage,
wherein the pneumatic piston is in contact with an upper side of the traversable guide carriage and is configured to apply a maximum first press-in force,
the electrical spindle drive includes at least two spindles, which penetrate the traversable guide carriage and which each has a spindle head at an underside of the traversable guide carriage, and
the traversable guide carriage includes stop contours in regions of the spindle heads of the at least two spindles, the stop contours being disposed spaced apart from the underside of the traversable guide carriage and on which the two spindles rest with their spindle heads if a second press-in force exceeds the first press-in force.

18. The device according to claim 17 , wherein the stop contours are one of hook contours and pots.

19. The device according to claim 17 , further comprising a detector including a sensor configured to monitor an electrical contact and switch off the device if at least one of a maximum first press-in force is exceeded and if the traversable guide carriage does not reach an end position.

20. The device according to claim 19 , wherein the electrical contact is between the traversable guide carriage and at least one of the at least two spindles of the electrical spindle drive.
