Abstract

A blind rivet setting device and method of setting a blind rivet. The device includes a housing; a pulling mechanism, arranged in the housing, that includes a chuck housing movable in a pulling direction and clamping jaws movable along a clamping distance in the chuck housing; an electric drive, structured and arranged to act on the chuck housing, that includes a control device; an electric battery structured and arranged as an energy source for the electric drive; and a spring structured and arranged in the chuck housing to apply a force to clamping jaws. For each clamping jaw, the chuck housing includes a guide path with a path base obliquely oriented to the pulling direction, and a back of each clamping jaw is supported against its respective path base over the clamping distance.

Claims (29)

1. A blind rivet setting device comprising:

a housing;

a pulling mechanism, arranged in the housing, the pulling mechanism including a chuck housing movable in a pulling direction and a plurality of clamping jaws movable along a clamping distance in the chuck housing;

an electric drive, structured and arranged to act on the chuck housing, the electric drive including a control device, a single position sensor for the pulling mechanism and a revolution counter;

an electric battery structured and arranged as an energy source for the electric drive;

for each clamping jaw, the chuck housing including a guide path with a path base obliquely oriented to the pulling direction, and a back of each clamping jaw is supported against the respective path base of each clamping jaw in a planar manner over the clamping distance; and

for each clamping jaw, a spring being structured and arranged in the chuck housing to apply a biasing force along the respective obliquely oriented path base of each guide path.

2. The blind rivet setting device according to claim 1 , wherein the electric drive is actuatable with a higher frequency than a working frequency.

3. The blind rivet setting device according to claim 1 , wherein the control device comprises a charge state monitor for the battery.

4. The blind rivet setting device according to claim 3 , wherein the charge state monitor is structured for at least one of a signaling and a shutoff following a last complete setting operation.

5. The blind rivet setting device according to claim 4 , wherein the battery comprises a data storage medium containing charging information.

6. The blind rivet setting device according to claim 1 , wherein the electric drive comprises an energy return feed.

7. The blind rivet setting device according to claim 1 , wherein the electric drive is structured to act on the chuck housing via a ball screw having a pitch of about 4 mm and less than 5 mm.

8. The blind rivet setting device according to claim 7 , wherein the ball screw comprises balls structured for a 5 mm pitch.

9. The blind rivet setting device according to claim 1 , wherein the housing comprises a front face and a lighting device located on the front face.

10. The blind rivet setting device according to claim 9 , wherein the lighting device is operable in at least two different modes.

11. The blind rivet setting device according to claim 1 , wherein the battery is a rechargeable battery comprising a first encoding readable by the blind rivet setting device and a second encoding readable by a charging device.

12. The blind rivet setting device according to claim 1 , wherein the battery is connectable to the housing via a sliding connection.

13. The blind rivet setting device according to claim 1 , wherein the battery is secured in the housing by at least two mechanical locks arranged one after another in a sliding direction of a sliding connection.

14. The blind rivet setting device according to claim 1 , wherein the pulling mechanism has a pulling distance of at least 25 mm.

15. The blind rivet setting device according to claim 1 , wherein the pulling mechanism comprises a spindle coupled to the chuck housing and a rotatable nut to drive the spindle.

16. The blind rivet setting device according to claim 15 , further comprising a transmission arranged between the electric drive and the rotatable nut.

17. The blind rivet setting device according to claim 1 , wherein the clamping jaws comprise one of a fluting or surface treatment to improve a gripping of a mandrel by the clamping jaws.

18. The blind rivet setting device according to claim 1 , wherein the ball screw comprises balls structured for a 5 mm pitch and the electric drive is structured to act on the chuck housing via a ball screw having a pitch of less than 5 mm.

19. A method of setting a blind rivet, using the blind rivet setting device of claim 1 , said method comprising:

grasping a mandrel of the blind rivet with clamping jaws biased to be linearly movable along a path obliquely oriented to a pulling direction of the mandrel; and

pulling the mandrel until a set head is formed.

20. The method according to claim 19 , wherein the pulling of the mandrel is achieved by pulling the chuck housing in which the clamping jaws are arranged via the electric drive.

21. The method of claim 20 , further comprising determining a position of the chuck housing while pulling the mandrel by at least one of a single position sensor and a revolution counter.
