Abstract
A crimping tool is provided including a rotary drive unit and removable extension arm with pivotal jaw arms. The removable extension arm is rotatable about its axis. A locking device is included in the jaw arm assembly such that the jaw arms may be securely positioned in a number of locations to accommodate various working angles. A logic circuit limits the movement of the jaw arms to one complete cycle for each trigger event.
Claims27
A crimping apparatus comprising:
- a rotary drive tool including a trigger mechanism and an output shaft;
- a transmission mechanism engaged with said output shaft;
- a jaw assembly including first and second jaws, wherein said transmission mechanism translates rotary motion of said output shaft into pivoting motion of at least one of said first and second jaws;
- wherein said transmission mechanism includes a first cam drivingly engaged with said output shaft;
- and
- wherein said first cam engages a rocker arm for rotating a second cam to cycle at least one of said first and second jaws between a closed position and an open position.
3 more elements
A crimping apparatus comprising:
- a rotary output device;
- a transmission mechanism attached to said rotary output device;
- a jaw assembly including a first and second jaw arm, one of said first and second jaw arms being pivotally attached to the other and drivingly engaged with said transmission mechanism such that said jaw arms relatively articulate between an open position and a closed position;
- wherein said transmission mechanism includes a shaft having a first end selectably attached to said rotary output device and a second end including a first cam attached thereto;
- and
- wherein said transmission mechanism includes a second cam variably influencing one of said first and second jaw arms for articulating said one of said first and second jaw arms between a closed and open position.
3 more elements
The crimping apparatus according to claim 11 further comprising an internal power source for providing electric power to said rotary output device.
A crimping apparatus comprising:
- a rotary drive tool including a trigger mechanism and an output shaft;
- a transmission mechanism engaged with said output shaft;
- and
- a jaw assembly including first and second jaws,
- wherein said transmission mechanism translates rotary motion of said output shaft into pivoting motion of at least one of said first and second jaws,
- wherein said jaw assembly includes at least one tab member for adjustably positioning said jaw assembly in a number of secure positions.
3 more elements
A crimping apparatus comprising:
- a rotary drive tool including a trigger mechanism and an output shaft;
- a transmission mechanism engaged with said output shaft;
- and
- a jaw assembly including first and second jaws,
- wherein said transmission mechanism translates rotary motion of said output shaft into pivoting motion of at least one of said first and second jaws,
- wherein said transmission mechanism and jaw assembly is supported by a housing which is rotatable relative to the rotary drive tool.
3 more elements
A crimping apparatus comprising:
- a rotary output device;
- a transmission mechanism attached to said rotary output device;
- and
- a jaw assembly including a first and second jaw arm, one of said first and second jaw arms being pivotally attached to the other and drivingly engaged with said transmission mechanism such that said jaw arms relatively articulate between an open position and a closed position,
- wherein said transmission mechanism and first and second jaw arms are supported by a housing which is rotatable relative to the rotary drive tool.
2 more elements
A crimping apparatus comprising:
- a rotary drive tool including an output shaft;
- a transmission mechanism including a clutch, said transmission engaged with said output shaft;
- and
- a jaw assembly including first and second jaws,
- wherein said transmission mechanism translates rotary motion of said output shaft into pivoting motion of at least one of said first and second jaws.
2 more elements
A crimping apparatus comprising:
- a rotary drive tool including an output shaft;
- a jaw assembly including first and second jaws;
- and
- a transmission mechanism including a clutch and an eccentric first cam,
- wherein said transmission mechanism is engaged with said output shaft and said first cam oscillates to engage said clutch at least once per rotation of said output shaft,
- wherein said transmission mechanism translates rotary motion of said output shaft into pivoting motion of at least one of said first and second jaws.
