Abstract
A blind rivet setting tool including a clamping assembly for releasably clamping a nosepiece in place such that a blind rivet can bear against the nosepiece while the mandrel thereof is pulled; and a method of changing nosepieces using the clamping assembly.
Claims19
A blind rivet setting tool, comprising:
- a jaw housing having a threaded outer surface at a distal end thereof and an abutment with an annular surface portion that extends in a plane orthogonal to a longitudinal axis of the blind rivet setting tool to define a first nosepiece receiving opening;
- a nosepiece releasably attached in the first nosepiece receiving opening, the nosepiece having a channel through which a mandrel of a blind rivet is received, and a recess with a hole in communication with the channel and configured to receive a ball configured to partially protrude through the hole into the channel to grip the mandrel;
- a pullback hull arranged in the jaw housing for axial movement with respect thereto;
- gripping jaws arranged in the pullback hull and moveable by the pullback hull to pull the mandrel to be set in use;
- and
- a clamp having a cap partially surrounding the pullback hull for releasable connection with the jaw housing to releasably clamp the nosepiece between the clamp and the gripping jaws in a manner that enables the blind rivet to bear against the nosepiece while the mandrel is pulled.
The blind rivet setting tool of 3, wherein the threaded outer surface comprises male threading.
The blind rivet setting tool of 1, wherein the clamp is engaged by threaded engagement of the cap to the jaw housing.
The blind rivet setting tool of 14, wherein the clamp is disengaged by threaded disengagement of the cap from the jaw housing.
The blind rivet setting tool of 1, wherein the clamp is engaged by rotating the cap relative to the jaw housing in a first direction to form a threaded engagement of the cap to the jaw housing.
The blind rivet setting tool of 16, wherein the clamp is disengaged by rotating the cap relative to the jaw housing in a second direction to produce a threaded disengagement of the cap from the jaw housing.
A blind rivet setting tool, comprising:
- a jaw housing having a threaded outer surface at a distal end thereof and an abutment with an annular surface portion that extends in a plane orthogonal to a longitudinal axis of the blind rivet setting tool to define a first nosepiece receiving opening;
- a nosepiece received in the first nosepiece receiving opening, the nosepiece having a channel through which a mandrel of a blind rivet is received, and a recess with a hole in communication with the channel and configured to receive a ball configured to partially protrude through the hole into the channel to grip the mandrel;
- an axially moveable pullback hull;
- gripping jaws, arranged in the pullback hull and moveable by the pullback hull to pull the mandrel to be set in use, the gripping jaws having a ramped surface configured to be engaged by the nosepiece;
- a motor and a torque transmission for causing the gripping jaws to grip and pull the mandrel of the blind rivet;
- and
- a clamp having a cap partially surrounding the pullback hull to releasably clamp the nosepiece between the clamp and the gripping jaws in a manner that enables the blind rivet to bear against the nosepiece while the mandrel is pulled, the cap having a threaded inner surface for threaded engagement with the threaded outer surface of the jaw housing and an inwardly extending annual lip defining a second nosepiece receiving opening that urges against a surface of the nosepiece when the threaded inner surface of the cap is threaded onto the threaded outer surface of the jaw housing.
A blind rivet setting tool, comprising:
- a jaw housing having a threaded outer surface at a distal end thereof and an abutment with an annular surface portion that extends in a plane orthogonal to a longitudinal axis of the blind rivet setting tool to define a first nosepiece receiving opening;
- a nosepiece received in the first nosepiece receiving opening, the nosepiece having a channel through which a mandrel of a blind rivet is received, and a recess with a hole in communication with the channel and configured to receive a ball configured to partially protrude through the hole into the channel to grip the mandrel;
- an axially moveable pullback hull;
- gripping jaws, arranged in the pullback hull and moveable by the pullback hull to pull the mandrel to be set in use, the gripping jaws having a ramped surface configured to be engaged by a ramped surface of the nosepiece;
- a motor and a torque transmission for causing the gripping jaws to grip and pull the mandrel of the blind rivet;
- and
- a clamp having a cap partially surrounding the pullback hull to releasably clamp the nosepiece between the clamp and the gripping jaws in a manner that enables the blind rivet to bear against the nosepiece while the mandrel is pulled, the cap having a threaded inner surface configured for threaded engagement with the threaded outer surface of the jaw housing to bring a nosepiece surface into engagement with the annular surface portion of the jaw housing.
