Clamping apparatus i.e. toggle lever clamping apparatus, for manufacturing of automated automobile to clamp metal sheet between clamping jaws, has resonator carrier acquiring pivoting angle of clamping arm relative to housing

摘要

The apparatus has a drive shaft (6) at which a piston cylinder is engaged by a toggle lever joint at an axial position to pivot a clamping arm (2) into a clamping position, and bring a clamping jaw (3) at the arm into a spacing position with respect to another jaw (4). A workpiece with material thickness is held in the clamping position by a clamping force, where the thickness corresponds to a distance of the jaws. A resonator carrier (7), a circuit board (9), a resonator coil, a capacitor, a sensor coil and a large coil surface acquire pivoting angle of the arm relative to a housing (1).
