Product Information

ROEMHELD Electric Swing Clamp Parallel Drive, B18320

The electric swing clamp is driven by a wear-resistant brushless DC motor. The motor speed is transformed by means of a gear and a threaded spindle into the swing and stroke movement of the piston rod. During the 180° swing of the clamping, an axial stroke of only 3 mm is required. If the clamping arm collides during the swing motion with a workpiece, the mechanism is protected against overload. The direct current motor is automatically and immediately switched off. When unclamping, the clamping arm always swings back to the off-position.

BENEFITS

• High clamping force

• Adjustable clamping force

• Clamping force monitoring

• FAILSAFE - High operating safety by a self-locking spindle drive

• Mechanical re-clamping by Belleville springs

• Swing angle up to 180° available

• Overload protection device in the case of collisions with the clamping arm

• Electric position monitoring and extensive self-monitoring with diagnostic options

• Clamping stroke control possible

• Low voltage 24 VDC

• Maintenance-free (500,000 cycles).

• Code class IP 67

Application Information

Electric swing clamps are used for clamping or holding of workpieces

- when the clamping and holding points shall be free for loading and unloading of the fixture

- when an extended functionality is required for automated systems

- when clamping elements have to be controlled individually

- where the clamping force must be maintained also after the separation from the energy supply

Thus, electric swing clamps are particularly suited for:

Packaging industry
Test systems
Special machines
Assembly equipment and robotics
Automatic manufacturing systems
Clamping fixtures with workpiece loading via handling systems

Function, Power & Control Info

Integrated control

The electronic control for the DC motor is on a board in the housing of the electric swing clamp.

Electric connection

Power supply and signal exchange for external control are transmitted by two short cables with plug-type connector. Cable sockets are available for the customer's connection (see connection accessories).

Safe touch voltage

The 24 VDC voltage is considered to be a "low voltage" and thus it is not dangerous for people in case of contact.

Power supply

For motor and electronic control a DC voltage of 24 V with a residual ripple of max. 10 % is required.

For the DC motor, we recommend the use of a switching power supply with a current output of 15 A per connected electric swing clamp. When operating several swing clamps at the same time, the line is to be enlarged correspondingly. The electronic control has to be supplied by a separate power supply (24 V DC/100 mA).

Adjusting ranges

After removal of the protection cover, the following adjustments can be made on the control board:

• Clamping force

• Swing speed

• Compensation of the clamping arm elasticity

The clamping force can also be adjusted via analogue input.

Integrated Feedback

Unclamped

• Clamping arm in off-position and unclamping process completed

Clamped

• Clamping arm within clamping area and clamping force obtained

• Clamping stroke control possible by output signal

Diagnostic options

• Extensive review on error conditions

• Signaling via error code (flashing signal) internally on control board or via external interface signal

• Error messages can be reset

• Review display after 500,000 cycles

You will find a complete description in the supplied operating manual.
