Abstract

A set of nosepieces are configured to attach to a rivet setting tool. The set of nosepieces comprises a first nosepiece with a longitudinal bore having a first diameter and an O-ring having a first color, and a second nosepiece with a longitudinal bore having a second diameter that is different than the first diameter and an O-ring having a second color that is different than the first color.

Claims (35)

1. A set of nosepieces, each nosepiece in the set configured to attach to a rivet setting tool, the set of nosepieces comprising:

a first nosepiece with a first longitudinal bore having a first diameter, a first detent, and a first O-ring configured to bias the first detent, the first O-ring having a first color; and

a second nosepiece with a second longitudinal bore having a second diameter that is different than the first diameter, a second detent, and a second O-ring configured to bias the second detent, the second O-ring having a second color that is different than the first color;

wherein the first O-ring has a first cross-sectional diameter and the second O-ring has a second cross-sectional diameter different from the first cross-sectional diameter.

2. The set of nosepieces of claim 1 , wherein each of the nosepieces further comprises a hexagonal ledge.

3. The set of nosepieces of claim 1 , wherein each of the nosepieces further comprises a circumferential groove in which their respective O-ring is arranged.

4. The set of nosepieces of claim 3 , wherein each of the nosepieces further comprises a radial bore in communication with their respective longitudinal bore and their respective circumferential groove, wherein each of their respective detents includes a ball detent arranged in the respective radial bore, and wherein each ball detent is biased radially inward by their respective O-ring.

5. The set of nosepieces of claim 4 , wherein in a biased position, each ball detent projects into their respective longitudinal bore.

6. The set of nosepieces of claim 1 , wherein each of the nosepieces further comprises an indicia to indicate a size of the diameter of their respective longitudinal bores.

7. The set of nosepieces of claim 1 , further comprising:

a third nosepiece with a third longitudinal bore having a third diameter that is different from the first and second diameters, a third detent, and a third O-ring configured to bias the third detent, the third O-ring having a third color that is different from the first and second colors, and

a fourth nosepiece with a fourth longitudinal bore having a fourth diameter that is different from the first, second, and third diameters, a fourth detent, and a fourth O-ring configured to bias the fourth detent, the fourth O-ring having a fourth color that is different from the first, second, and third colors.

8. The set of nosepieces of claim 7 , wherein the first diameter is 3/32″, the second diameter is ⅛″, the third diameter is 5/32″, and the fourth diameter is 3/16″.

9. A rivet tool set, the rivet tool set comprising:

a rivet tool including

a housing,

a pulling head within the housing,

a handle with a grip portion defining a generally longitudinal direction, and

a plurality of jaws between which a mandrel of a rivet is receivable, the jaws arranged within a setting end of the housing; and

a set of nosepieces, each nosepiece in the set removably attachable to the setting end of the housing, the set of nosepieces including

a first nosepiece with a first longitudinal bore having a first diameter, a first detent, and a first O-ring configured to bias the first detent, the first O-ring having a first color;

a second nosepiece with a second longitudinal bore having a second diameter that is different than the first diameter, a second detent, and a second O-ring configured to bias the second detent, the second O-ring having a second color that is different than the first color; and

wherein the rivet tool further includes an on-board storage receptacle defining individual recesses each configured to receive an unused one of the first or second nosepieces, and

wherein the grip portion is disposed between the on-board storage receptacle and the pulling head in the generally longitudinal direction.

10. The rivet tool set of claim 9 , wherein each of the nosepieces further comprises a circumferential groove in which their respective O-ring is arranged.

11. The rivet tool set of claim 10 , wherein each of the nosepieces further comprises a radial bore in communication with their respective longitudinal bore and their respective circumferential groove, and wherein each of their respective detents includes a ball detent arranged in the respective radial bore, and wherein each ball detent is biased radially inward by their respective O-ring.

12. The rivet tool set of claim 11 , wherein in a biased position, each ball detent projects into their respective longitudinal bore.

13. The rivet tool set of claim 9 , wherein each of the nosepieces further comprises an indicia to indicate a size of the diameter of their respective longitudinal bores.

14. The rivet tool set of claim 9 , further comprising:

a third nosepiece with a third longitudinal bore having a third diameter that is different from the first and second diameters, a third detent, and a third O-ring configured to bias the third detent, the third O-ring having a third color that is different from the first and second colors, and

a fourth nosepiece with a fourth longitudinal bore having a fourth diameter that is different from the first, second and third diameters, a fourth detent, and a fourth O-ring configured to bias the fourth detent, the fourth O-ring having a fourth color that is different from the first, second and third colors.

15. The rivet tool set of claim 14 , wherein the first diameter is 3/32″, the second diameter is ⅛″, the third diameter is 5/32″, and the fourth diameter is 3/16″.

16. The rivet tool set of claim 14 , wherein the rivet tool further comprises an on-board storage receptacle defining individual recesses each configured to receive an unused one of the first, second, third, or fourth nosepieces such that their respective O-rings are exposed above the respective individual recess for an operator to identify.

17. The set of nosepieces of claim 1 , wherein the first O-ring has a first outer diameter and the second O-ring has a second outer diameter different from the first outer diameter.

18. The set of nosepieces of claim 17 , wherein the second diameter of the second longitudinal bore is larger than the first diameter of the first longitudinal bore, and wherein second outer diameter of the second O-ring is larger than the first outer diameter of the first O-ring.
