The enclosed rotary lever clamp with pneumatic position sensing is particularly suitable for clamping fixtures where there are a lot of chips. The clamping lever is designed so that the chips are wiped off at the front and top by a metal wiper. In addition, there is an internal soft wiper and sealing air can be applied.

The double-acting rotary lever clamps are used in clamping fixtures that are supplied with oil via drilled channels. The linear stroke is used proportionally to swivel the clamping lever in, which fixes the workpiece. To release, the clamping lever swivels back far enough so that the workpiece can be removed without collision. Clamping levers are not included in the scope of delivery! Standard clamping levers made of steel and in different lengths can be ordered as accessories. The cylinder can also be fitted with individual clamping levers. The clamping forces depend on the length of the clamping lever. The housed rotary lever clamps have the same installation dimensions as the double-acting rotary lever clamps from data sheet 250-10/250-20 and are therefore interchangeable.

Operating conditions:
The clamping lever is coupled to the piston rod. With the double-acting rotary lever clamps, the clamping lever is opened by the pressure medium. When installing the rotary lever clamps, the flange surface should be adapted to the height of the workpiece. The clamping point should be in a horizontal position. Workpiece tolerances can thus be compensated for despite the short clamping stroke.

Pneumatic position sensing:
The clamping levers are equipped with elastic sealing plugs on both sides. There are two drilled channels in the rotary lever clamp through which compressed air can be fed into the clamping lever guide of the housing. The holes are arranged in such a way that they are sealed by the sealing plugs of the clamping lever in the clamping or unclamping position. This creates a pneumatic pressure increase in the line, which can be monitored in the respective position using commercially available pneumatic pressure switches. The pressure switch registers the pneumatic pressure increase and generates an electrical signal which is forwarded to the control unit.

Installation instructions:
The rotary lever clamp is suitable for any installation position.

Rotary linear clamp Hydraulic

Hydraulic double-acting, pmax. 250 bar, pneum. query clamped and/or unclamped (also simultaneously!) During the clamping process, the rotary linear clamp first rotates the clamping arm and then switches to a linear movement. This means there are no lateral forces at the clamping point and workpiece tolerances are compensated for by the linear stroke.
