Power clamp

Pneumatic clamps have the following advantages compared to hand clamps: The operator is relieved of frequent clamping. Several clamps can be activated at the same time and can be closed in a specific sequence. Single or multiple clamps can be activated from varying positions by machine control or hand control. Because of the toggle system: the clamp remains closed if the air supply fails. the air consumption is low due to the large end ratio. pivoting the clamping arm achieves a large opening travel. optimum force and movement ratios are achieved. VL = air consumption per complete cycle in dm³ at 6 bar. Selection criteria: To select the correct size of pneumatic clamps, the possible clamping force at 6 bar (any compressed media are permissible, maximum pressure 10 bar) is specified besides the retaining force. F3 is the possible clamping force that the clamp exerts on the end of the clamping arm, F4 the force it exerts on the fulcrum side.

The functioning principle make the wedge clamps ideal for series clamping. The wedge form can exert high clamping forces. These wedge clamps can be mounted in grid holes or T-slots. Tightening the socket screw moves the wedge down and the jaws out pressing the workpieces against the fixtures fixed stops. The wedge has a slightly elongated hole allowing for movement to compensate for tolerances.

Fasten the floating clamp to the fixture with the M12 screw. Adjust the height stop and the swivel range using the blue sleeve and lock with the 3x2.5 mm grub screws. When setting the height leave generous clearance above. For safe operation the M12 tapped hole must always be closed. For specific clamping applications the standard jaws can be altered or replaced. Form B: Fasten the floating clamp with M6 fastening holes to a fixture. Adjust the height stop and pivot range using the blue adjusting sleeve and clamp with grub screws (4x AF 2.5). When setting the height limit, allow ample play at the top. For specific clamping situations, the standard jaw plates can be modified or replaced.

The pneumatic hold-down clamp is suitable for clamping workpieces from above. This clamp is operated with standard pressure compressed air. The large swivel angle of the clamping arm makes it easy to insert and remove the workpieces without any obstructions, guaranteeing optimum accessibility to the workpiece. The block design of the housing offers universal fastening possibilities, which means that the clamp can be optimally adapted to the workpiece being clamped. Self-aligning pads with a smooth or serrated faces can be fitted in the clamping arm, enabling rough or machined workpieces to be clamped. These pneumatic clamps can be placed in multiple positions on the workpiece and operated in any particular order. They can be controlled manually or automatically. As these clamps are pneumatically actuated, they relieve the operator, particularly where frequent clamping processes are carried out.
