The computer
controlled test stand contains electro-magneticjoint simulators for continuous testing of
nutrunners (air + dc-electric),battery tools, pulse tools and torque wrenches on
site at theassembly line.
Nutrunners and pulse tools change their
behavior according to the
joint-hardness. Therefore the
test stand simulates the joint-hardness
of the assembly operation at
which the nutrunneror pulse
tool will be used.
The joint simulation can be completed very
quickly, because it is not
necessary to back of a bolt or nut. The electro-magnetic
joint simulatorimmediately
releases after the job is done. A run-down takes approx.
3s.Within this time the test stand measurestorque, rotation angle andtool speed (RPM).
Release torque wrenches (click-wrenches) can be
tested on the simulatorsas
well.
All readings are displayed on the screen and analyzed
in thepowerfulCEUS 8.2 software.
The mobile test stand is built on a
movable frame completely coveredwith up to 5 joint simulators from
0.5 N·m to a maximum
of 500 N·m
(4 in.lb - 370 ft.lb.). External joint simulators are
available up to 4000 N·m
An exchangeable battery provides power
independent of the mains for
approx. 3,500 measurements. The system
can be operated on the mains
continuously as well.
A connection of external torque/angle transducers
allows the systemto "learn"
the joint hardness of an operation through joint
scanning.The system will be
able to simulate a specific joint behavior aftercompleting a measurement in the original
operation.
The CEUS 8.2 PC
software can be supplied as a stand-alone or networkversion. Torque tools are monitored automatically
in the test schemeand
calibration certificates are printed according to the
customer'srequirements.
CEUS 8.2
- The powerful risk management software tracks tools,
organizes test planning and sets test specifications.
