B 1.8291 Flat lever clamps
Advanced Link System, pneumatic position monitoring
built-in and block-type, double acting, max. operating pressure 120 bar
The flat lever clamp is a compact hydraulic clamping element for fixtures with oil supply through drilled channels. The flat clamping lever allows machining of surfaces that are only a few millimetres above the clamping point.
Double-acting versions are advantageous for time and cycle-dependent installations, since the return stroke is effected in a precisely defined time and the pneumatic position monitoring of the clamping lever is possible. This series can be directly connected to the low pressure hydraulics of machine tools with 70 to 120 bar.
When pressurising the hinge clamp, the piston moves upwards against the rear edge of the clamping lever and swivels the clamping lever to the clamping position. The piston force is deviated by 180° onto the workpiece. The clamping force depends on the operating pressure and the length of the clamping lever. When unclamping the flat lever clamp, the clamping lever is swivelled back to the off-position by means of a hook-shaped carrier on the piston. The pneumatic position monitoring allows the monitoring of both final positions of the clamping lever.
Advanced Link System
The newly developed lever kinematics enable trouble-free, process-safe operation.
