摘要
A rivet nut tool has a primary gear driven by a motor and a gear assembly coupled to the primary gear for rotation for moving a pull screw by a movement distance to achieve a stroke. The tool has a selection button for selecting a stroke value and a pull-riveting force. A control processor receives the selected stroke value and pull-riveting force. A count sensor is used to measure the rotational movement of a primary gear in terms of signal counts for determining the stroke achieved by the pull screw. The selected stroke value is presentable as a preset count value. When the signal count reaches the preset count value, or the motor current exceeds the current needed for the selected pull-riveting force, the control processor is configured to reverse the rotation direction of the motor so as to return the pull screw to its start position.
