In assembly applications, it is common to come across a need to tighten fluid line fittings into various components and for various fluids and sizes.
The torque requirement for these applications is usually at least function, if not safety critical- which means the torque needs to be correctly applied every cycle AND at production speed. This means using a transducer controlled assembly tool to do the job and not a hand wrench.
But there is a problem: with the fluid line attached, how is it possible to use a power tool to do the job quickly and accurately and get the tool off the fitting with the fluid line attached??
This is the exact reason open end / tube nut wrench attachments exist: to solve this problem.
The QX Series Angle wrenches supports integration with geared offset open end / tube nut attachments available from a variety of suppliers. These enable transducerized power tools to be used for these applications by removing and/or adapting the right angle head of the QX Series Angle wrench with one of these open end / tube nut attachments.
One of the main considerations that needs to be addressed is how the user wants the tool to function following relative to the tightening and removal processes for the tool. To address this, we offer several tube nut modes to select from. These are explained and demonstrated below.
Here are the tube nut modes available - set using Assembly Wizard:
1) Momentary Reverse
-
- Normal forward operation.
- To run the Tubenut Mode the Fwd/Rev switch must be pressed.
- If the Fwd/Rev switch is released the tool stops.
- Otherwise, the tool will stop when the Tubenut Parameter Reverse Target Torque is reached.
2) 2 Handed Reverse
- Normal forward operation.
- To run the Tubenut Mode the trigger and Fwd/Rev switch must be pressed simultaneously.
- If either is released the tool stops.
- Otherwise, the tool will stop when the Tubenut Parameter Reverse Target Torque is reached.
3) Trigger Only
- Tool will alternate between the Tightening Mode and the Tubenut Mode with each trigger pull.
- The Blue LED indicates that the next trigger press will run the Tubenut Mode.
4) Momentary Toggle Direction
- Pressing the Fwd/Rev switch will switch between the Tightening Mode and the Tubenut Mode.
- The Blue LED will indicate that the tool is in Tubenut Mode.
5) Full Two Handed Operation
- Requires both the trigger and Fwd/Rev switch to be pressed simultaneously for the tool to run in either the Tightening Mode or Tubenut Mode.
- The tool will alternate between the Tightening Mode and the Tubenut Mode.
