Lever arm to payload
The product is a combined rotating and gripping module.
Electric rotary drive EHMD-...-RE:
The rotary movement of the stepper motor is transmitted directly to the gripper
via the motor shaft and can be freely positioned. The stepper motor incre-
mental encoder can be used for closed loop control and outputs a zero pulse
for homing per gripper revolution. The zero pulse ZP of the encoder and the
longitudinal axis of the gripper are factory-aligned parallel to the mounting
surface.
Electric gripper drive EHMD-...-GE/-GE-16:
The rotary movement of the stepper motor is transferred to the gripper jaws
via a mechanism and can be freely positioned. The stepper motor incremental
encoder can be used for closed loop control. A defined gripping force can be
generated in closed loop control with servo drives with torque limitation. A
defined gripping force can be generated in positioning mode by a spring in
the gripper drive with servo drives without torque limitation. After the gripper
fingers are in contact with the workpiece, the gripper drive is moved further
by a defined distance sforce and the spring is tensioned. If the power supply is
interrupted, the gripping force may drop to the residual gripping force.
Pneumatic gripper drive EHMD-…-GP:
The linear movement of the pneumatic cylinder is transferred to the gripper
jaws via a mechanism. Two positions on the pneumatic cylinder can be moni-
tored with proximity switches. If the compressed air supply fails, the gripping
force is not maintained. Gripping force can be backed up, e.g. by an uninter-
ruptable compressed air supply.
