Cl = clamping, Uncl = unclamp
* Specifications with clamping arm, standard

Design:

Cylinder barrel made of steel, hardened and burnished. Piston rod nitrided. Piston rod with internal thread. O-ring for flange seal. Wiper at the piston rod. Clamp arm not supplied as standard. Oil supply via threaded connection or oil channel in the fixture body.

Application:

The swivel clamp is used in fixtures in which the workpiece must be freely accessible and inserted from above. Even workpieces with difficult shapes can be clamped using special clamp arms (available on request).

Features:

The swing motion is executed via three ball guides, thereby increasing positioning accuracy, repeat accuracy and service life.

Note:

The piston stoke is executed with spheres, so volume flow Q max. must be complied with. Clamping arm length and clamping arm weight must be strictly observed. No force may be applied to the piston when mounting accessories to it. To equalise height differences on the workpiece, the vertical clamping path must be 50% of the clamping stroke. When placing into operation, ensure that all air is bled from the system.
To throttle the oil feed, the throttle/check valve no. 6916-12-01 for G1/8 can optionally be used. Other swivel angles are available on request.

Formula to determine the total mass moment of inertia and the volume flow:
total mass moment of inertia Jges. [kgm²]
Clamp arm mass moment of inertia JH [kgm²]
Piston mass moment of inertia JK [kgm²]
Clamp arm load mH [kg]
Centre of gravity distance Ls [m]
Jges. = JK + JH + mH x Ls² [kgm²]

Volume flow Qmax. [cm³/s]
Volume clamp Vol.sp [cm³]
Minimum permitted clamp time tmin. [s]
Qmax. = Vol.sp / tmin. [cm³/s]

Suitable clamp arms are 6951-XX.
