Automatic Tool Tester
|
|
The computer
controlled test stand contains electro-magnetic
joint simulators for continuous testing of
nutrunners (air + dc-electric),
battery tools, pulse tools and torque wrenches on
site at the assembly 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 nutrunner or 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 simulator immediately
releases after the job is done. A run-down takes approx.
3s.Within this time the test stand measures
torque, rotation angle and
tool speed (RPM).
Release torque wrenches (click-wrenches) can be
tested on the simulators as
well.
All readings are displayed on the screen and analyzed
in the powerful
CEUS 8.1 software. |

The mobile test stand is built on a
movable frame completely covered
with 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 system to "learn"
the joint hardness of an operation through joint
scanning. The system will be
able to simulate a specific joint behavior after
completing a measurement in the original
operation.
The CEUS 8.1 PC
software can be supplied as a stand-alone or network
version. Torque tools are monitored automatically
in the test scheme and
calibration certificates are printed according to the
customer's requirements.
