Use a cylinder with a lock valve (safety valve, check valve) incorporated in
case of sudden hydraulic pressure drop due to blackout, malfunction of
the hydraulic pump, etc. Further, use a solenoid valve with a circuit that
retains the gripping position when no current is carried.
・
If the hydraulic pressure suddenly drops due to blackout or malfunction of the hydraulic
pump, etc., this is dangerous as work will fly out.
・
Lock valve retains the hydraulic pressure inside the cylinder temporarily, when the
hydraulic pressure suddenly drops due to blackout or malfunction of the hydraulic pump,
etc.
Important Safety Precautions
WARNING
Failure to follow the safety precautions below could result in
serious injury or death.
Do not modify the chuck in a way not permitted by the manufacturer.
・
It may not only break the chuck but the chuck
and the work may fly out, which is
dangerous.
・
If you attach a locator or jig on the chuck body surface, only process work in an
acceptable range
Periodically supply adequate grease. Turn off power before adding
grease.
・
Insufficient grease supply lowers the gripping force, causes operation failure due to
lower hydraulic pressure, lowers the gripping precision, and causes abnormal wearing
and seizing, etc.
・
This is dangerous as the work could fly out from a drop in the gripping force.
