NUT RUNNER |
| 摘要 |
In a nut runner with a motor (3) for generating a torque, a tool holder (9) which is operatively connected with the motor (3) and transmits the generated torque to a tool, a measuring device (7) which continuously measures at least one measurement quantity for determining the torque and forwards the measurement value, and a control device (12) which is connected with the motor (3) and the measuring device (7) and controls the operation of the motor (3) such that after starting it generates a continuously increasing torque, and which shuts off the motor upon reaching a setpoint measurement value, the measuring device is a torque sensor (7) and the torque sensor (7) is arranged between the motor (3) and the tool holder (9). |

1. A nut runner, comprising
a motor for generating a torque, a tool holder which is operatively connected with the motor and transmits the generated torque to a tool, a measuring device which continuously measures at least one measurement quantity for determining the torque and forwards the measurement value, a control device which is connected with the motor and the measuring device and controls the operation of the motor such that after starting it generates a continuously increasing torque, and which switches off the motor upon reaching a set point measurement value, wherein the measuring device is a torque sensor (7) and the torque sensor (7) is arranged between the motor (3) and the tool holder (9). |
