Toggle clamp, in particular for use in car bodywork construction

摘要

A toggle clamping device or piston-cylinder unit including mechanism for adjusting the opening angle of the clamping arm. Within the cylinder there are a number of interrogator devices that function to determine the position of pistons within the cylinder and transmit this information to a micro processor. The location of the interrogator devices can be adjusted. Also within the cylinder there are damping mechanism, the location of which can also be adjusted. When the toggle clamping device is in use, the opening angle of the clamping arm, the final-position of the interrogator devices and the final-position of the damping mechanism can be adjusted and locked simultaneously and jointly through a single adjusting element from the outside of the device without dismantling the toggle clamping device.
