The test stand amends the ToolTorqueTester TTT-300 and can be utilized to approve and calibrate manually operated torque tools with release mechanism or indicator, as classified in ISO 6798. Inserting and fixing the tool under test into the test stand allows a precise momentum transfer as required by the ISO standard.
The quick clamping device can be a in X-,Y- and Z-direction perfectly to the wrench; vertically (X-axis) to adjust the lever length, horizontal (Y-axis and Z-axis) to adopt the hold. Turning the handwheel the wrench moves perfectly centered to the measuring device orbital by 0.5° per revolution and the momentum increases smoothly and even as required by ISO 6789 until the release mechanism is activated. Torque screwdrivers are fixed at the handle in a 3-jaw-chuck.
The chuck is mounted onto a quick release clamping fixture and can be moved in Y-direction to adapt to the length of the tool. Turning the handwheel moves the screwdriver perfectly aligned with the measuring axis of the tool torque tester and the momentum can be increased smoothly and even as required by ISO 6789 until the release mechanism is activated. For test of motorized drivers, the turning device can be blocked.
