Description:

The clamping and supporting element is a double-acting hydraulic cylinder with a mechanical locking according to the wedge principle. Due to the self-locking design of the wedge priniciple the element has besides the clamping function also a supporting function. If the workpiece yields or the contact bolt digs deeper into the material due to machining forces or vibrations, the clamping and supporting element re-clamps provided that sufficient clamping pressure is available. The clamping bolt is protected against torsion and provided with interior thread to allow screwing in of individual contact bolts or shaped parts. Hydraulic oil is supplied through drilled channels in the fixture body, either horizontally directly in the cartridge-type hole or vertically in the built-in housing, available as accesory, that offers alternatively also the possibility of tube connections. The version with extended piston rod is provided for mounting of inductive or pneumatic position monitorings.

Application:

Clamping and supporting elements are used for the following applications:

• Workpieces must be firmly clamped even in case of a pressure drop in the hydraulic system
• Ribbings or webs of workpieces must be clamped by opposite clamping elements in a neutral position and then immovably locked.
• The machining forces are relatively high and directed against the clamping force
• Vibrations in the workpiece have to be cushioned

The round body design of the cartridge-type version allows direct and space-saving installation in the fixture body. Particularly suitable for clamping and supporting in bore holes or recesses of the workpiece.
