Abstract
Illustrative embodiments of controlled pivot impact tools are disclosed. In at least one illustrative embodiment, an impact tool may comprise a hammer configured to rotate about a first axis and to pivot about a second axis different from the first axis, where the hammer includes a cam groove formed in an outer surface of the hammer, an actuator coupled to the cam groove of the hammer and configured to pivot the hammer about the second axis between a disengaged position and an engaged position based on a position of the actuator along the cam groove, and an anvil configured to rotate about the first axis in response to being impacted by the hammer when the hammer is in the engaged position.
Claims18
An impact tool comprising:
- a hammer configured to rotate about a first axis and to pivot about a second axis different from the first axis, the hammer including a cam groove formed in an outer surface of the hammer;
- an actuator coupled to the cam groove of the hammer and configured to pivot the hammer about the second axis between a disengaged position and an engaged position based on a position of the actuator along the cam groove;
- and
- an anvil configured to rotate about the first axis in response to being impacted by the hammer when the hammer is in the engaged position;
- further comprising a controller configured to:
- sense a rotational speed of the hammer about the first axis;
- and
- cause the actuator to pivot the hammer from the disengaged position, in which the hammer rotates about the first axis without impacting the anvil, to the engaged position, in which the hammer impacts the anvil, in response to the rotational speed of the hammer achieving a threshold rotational speed.
An impact tool comprising:
- a hammer configured to rotate about a first axis and to pivot about a second axis between a first position and a second position, the second axis being parallel to and spaced apart from the first axis, the hammer having a void formed therein;
- and
- an anvil disposed within the void of the hammer and configured to rotate about the first axis in response to being impacted by the hammer,
- wherein the hammer is configured to impact the anvil while in the first position and to rotate freely about the anvil while in the second position;
- wherein:
- the hammer is configured to impact the anvil while in the first position when rotating about the first axis in a clockwise direction;
- and
- the hammer is further configured to pivot about the second axis between the second position and a third position and to impact the anvil while in the third position when rotating about the first axis in a counterclockwise direction.
An impact tool comprising:
- a hammer configured to rotate about a first axis and to pivot about a second axis, the second axis being parallel to and spaced apart from the first axis, the hammer having a void formed therein;
- an anvil disposed within the void of the hammer and configured to rotate about the first axis when impacted by the hammer;
- and
- an actuator positioned along a third axis that is parallel to and spaced apart from both the first axis and the second axis, wherein the actuator engages the hammer such that movement of the actuator along the third axis causes the hammer to pivot about the second axis.
