roemheld b1.8251 Series Hinge Clip
b 1.The 8251 Series Hinge Clamp is a low-cost hydraulic clamping element with a variety of mounting and connection possibilities. If the clamping rod is retracted, the loading and unloading of the clamp can be realized.
A clamping groove in the workpiece that is slightly wider than the clamping rod is sufficient as a clamping surface. The special kinematics make it possible to clamp the workpiece with almost no lateral loads, which are very sensitive to deformation.
When pressurizing the element, the piston moves up and rotates the clamping rod on the hinge forward while rotating down onto the workpiece. The piston force deviates by 180° and can be used as a clamping force with little to no loss of efficiency.
If the horizontal plane of the clamping surface is exactly in the center of the clamping range, no side load is introduced to the workpiece.
The body can be recessed into the fixture up to the flange. In addition, the midplane can also be used for height adjustment. All versions are optionally available with an extended piston rod and inductive or pneumatic position monitoring.
