Advantages:

• Minimum dimensions
• Partially immersed body
• Mounting without pipes
• Unimpeded loading and unloading of the fixture
• Workpiece clamping without any side loads
• Flat clamping lever can be swivelled into small recesses
• Long clamping lever (blank) adaptable to the workpiece
• Pneumatic control of the clamping lever position (standard only double acting))
• Metallic wiper edge for piston rod
• Mounting position: any

Description:

When pressurising the hinge clamp, a 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 hinge clamp, the clamping lever is swivelled back to the off-position by means of a hook-shaped carrier on the piston. Unclamping is made either hydraulically or when using a single-acting element with spring force. The pneumatic position monitoring allows the monitoring of both final positions of the clamping lever.

Application:

The hinge clamp with flat clamping lever is a compact hydraulic clamping element for fixtures with oil supply through drilled channels. Due to the minimum space required, the hinge clamp with flat clamping lever is especially suitable for fixtures with little space for the installation of hydraulic clamping elements. The flat clamping lever allows machining of surfaces that are only a few millimetres above the clamping point.
Typical applications are:

• Multiple clamping fixtures with many workpieces that are closely arranged
• Rotary indexing fixtures in horizontal and vertical machining centres
• Assembly lines
