Application of PClamp

PClamp is a modular designed system for the clamping of rods and  peumatic cylinder.

Advantages:
- Pneumatic clamping with high forces
- Optimum safety clamping ? if the pneumatic fail the system is locked
- The values of hydraulic clamps are reached and exceeded
- Low system costs in comparison to hydraulics
- Simple installation
- Wide range for many shaft sizes can be delivered

The clamping forces can be enlarged by up to four clamping modules cover and base plate. Plamp is perfectly suitable for clamping of rods with a diameter from 12 to 40 mm. Dimensions of flange and outer dimensions are conform to  metric cylinder ISO 6431. The lengths of PClamp vary according to the choosen clamping force depending on the numbers of modules. 
 
PClamp N: Standard version Comprising the standard cover plate, one to three clamping units and base plate with connections for initiators as well as air inlet. Suitable for linear and rotary loads.

PClamp X: Version with additional safety mechanism for highest safety standards for vertical axes Models with improved safety for vertical axes. After clamping the piston rod, the clamping mechanism can only be released when the axis is moved vertically upwards. The clamping unit is identical to the versions N and ISO.

PClamp ISO: Version for ISO pneumatic cylinder Cover plate and base plate are matched to the dimensions on the flange dimen­sion of the ISO cylinder. Due to the integrated attachments in the housing, the ISO version is ideal for use with standard cy­linders. The clamping unit is identical to versions N and X.

PClamp E: Compact version for lower clamping forces PClamp E has a lower overall height ? ideal for applications with limited installation space or operating ranges in which lower holding forces are required. Sensors can not be used. The clamping unit has a different outward appearance than Version N, X and ISO, although the active principle is iden­tical.
 
Operating principle for the example of PClamp N
PClamp N released: Pressure is applied to the air chambers between the spring steel sheets. The spring steel sheets bend outwards, reducing their radial width. The clamping collet can therefore expand, releasing the rod.

PClamp N clamped: The air chambers between the spring steel sheets are vented, the elastic spring steel sheets return to their original position, thereby clamping the collet against the rod. In this condition, the PClamp N is able to stop both rotary motion as well as linear motion.
