B 1.8251 Hinge clamp

The hinge clamp is a low-cost hydraulic clamping element with many installation and connecting possibilities. If the clamping lever is completely retracted, unimpeded loading and unloading of the fixture can be effected.
A clamping recess in the workpiece a little bit wider than the clamping lever is sufficient as clamping surface. The special kinematics allow clamping nearly without side loads of workpieces which are very sensitive against deformation.

When pressurising the element, the piston moves upwards and swivels the clamping lever over the hinges forwards and at the same time downwards onto the workpiece. The piston force is deviated by 180° and is available as clamping force with virtually no loss of efficiency.
If the level of the clamping surface is exactly in the centre of the clamping range, no side loads are introduced into the workpiece.

The bodies are recessible in the fixture up to the flange. Alternatively intermediate plates are available for height adjustment.
All versions are optionally available with extended piston rod and with inductive or pneumatic position monitoring.
