Blind rivet nut-setting tool
A blind rivet nut-setting tool includes an output shaft defining a longitudinal axis. The output shaft is moveable along the longitudinal axis between a first position and a second position. The blind rivet nut-setting tool further includes a first motor configured to rotate the output shaft about the longitudinal axis in response to an external force moving the output shaft in a rearward direction from the first position to the second position. The blind rivet nut-setting tool further includes a second motor configured to translate the output shaft along the longitudinal axis in the rearward direction.
1. A blind rivet nut-setting tool comprising:
an output shaft defining a longitudinal axis, the output shaft moveable along the longitudinal axis between a first position and a second position;
a first motor configured to rotate the output shaft about the longitudinal axis in response to an external force moving the output shaft in a rearward direction from the first position to the second position;
a drive shaft configured to receive torque from the first motor, the drive shaft engaged with the output shaft at a rear end of the output shaft, such that the output shaft is configured to receive torque from the drive shaft in response to the drive shaft receiving torque from the first motor; and
a second motor configured to translate the output shaft along the longitudinal axis in the rearward direction,
wherein the second motor is configured to translate the output shaft in the rearward direction toward a third position that is rearward of the second position.
2. The blind rivet nut-setting tool of claim 1 , wherein the rear end of the output shaft extends into a recess of the drive shaft, and wherein the recess has a non-circular cross-sectional shape, and wherein the rear end of the output shaft has a non-circular cross-sectional shape that corresponds to the non-circular cross-sectional shape of the recess.
3. The blind rivet nut-setting tool of claim 1 , further comprising a limit switch that is activated when the output shaft is moved from the first position to the second position, wherein the first motor rotates the output shaft about the longitudinal axis in response to the limit switch being activated.
4. A blind rivet nut-setting tool comprising:
an output shaft defining a longitudinal axis, the output shaft moveable along the longitudinal axis between a first output shaft position and a second output shaft position;
a carrier moveable along the longitudinal axis between a first carrier position and a second carrier position;
a first motor configured to rotate the output shaft about the longitudinal axis in response to the output shaft moving in a rearward direction from the first output shaft position to the second output shaft position;
a second motor configured to translate the carrier along the longitudinal axis between the first carrier position and the second carrier position; and
a cam member rotated by the second motor and including a pin arranged in a lobe of the carrier, such that in response to the cam member being rotated in a first direction by the second motor, the carrier is translated along the longitudinal axis from the first carrier position to the second carrier position,
wherein the output shaft is translated along the longitudinal axis in the rearward direction when the second motor moves the carrier from the first carrier position to the second carrier position.
5. The blind rivet nut-setting tool of claim 4 , further comprising a limit switch that is activated when the output shaft is moved from the first output shaft position to the second output shaft position, wherein the first motor rotates the output shaft about the longitudinal axis in response to the limit switch being activated.
6. The blind rivet nut-setting tool of claim 4 , wherein in response to the carrier reaching the second carrier position, the second motor moves the carrier along the longitudinal axis in a forward direction from the second carrier position toward the first carrier position.
7. The blind rivet nut-setting tool of claim 4 , further comprising a drive shaft configured to receive torque from the first motor, the drive shaft engaged with the output shaft at a rear end of the output shaft, such that the output shaft is configured to receive torque from the drive shaft in response to the drive shaft receiving torque from the first motor.
8. The blind rivet nut-setting tool of claim 4 , further comprising a magnet on the cam member and a sensor configured to detect the magnet when the carrier is in the second carrier position, wherein in response to the sensor detecting the magnet, the second motor rotates the cam member in a second direction that is opposite the first direction to move the carrier in a forward direction from the second carrier position toward the first carrier position.
9. The blind rivet nut-setting tool of claim 4 , wherein the carrier includes a bore and the output shaft includes a flange arranged in the bore, such that in response to the carrier moving from the first carrier position to the second carrier position, the output shaft is translated rearward along the longitudinal axis.
10. The blind rivet nut-setting tool of claim 9 , further comprising a spring arranged in the bore and engaged against the flange of the output shaft, such that the spring biases the output shaft toward the first output shaft position.
11. The blind rivet nut-setting tool of claim 9 , further comprising a limit switch that is activated when the output shaft is moved from the first output shaft position to the second output shaft position, wherein the first motor rotates the output shaft about the longitudinal axis in response to the limit switch being activated.
12. The blind rivet nut-setting tool of claim 11 , wherein the limit switch is arranged in the bore and includes an actuating arm, and wherein the limit switch is activated when the flange of the output shaft engages against and moves the actuating arm from a neutral position to an actuating position in response to the output shaft moving from the first output shaft position to the second output shaft position.
