Fig. 2.2: Pneumatic-mechanical clamp | Tensioning and clamping with compressed air is mainly used in applications involving mechanisation and automation. Pneumatic cylinders or motors fix and position the tools needed for work processes. This can be done by linear and rotary movement, and also by swivel movement. The energy in the compressed air is converted directly into force and movement through the exertion of pressure. The amount of tensioning force required must be dispensed with precision. |
