Abstract:
The invention relates to a toggle clamp device, in particular for use in vehicle body manufacturing in the automotive industry. The worldwide industry standard for the range of toggle clamps in the automotive industry contains the same technical data for the structural dimensions, clamping and retaining forces and cylinder diameters. Deviating from this standard while maintaining the technical data, according to the invention, smaller cylinder diameters are used which lead to a reduction in compressed air or energy consumption of between 25 to 60%.

Claim (Index 1):
A toggle clamp device, in particular for use in vehicle body manufacturing in the automotive industry, with connection dimensions determined according to standard specifications in the industry, for example for bores with a thread on the clamping head, for arranging the toggle clamp device on an assembly line, with a drive unit which is to be acted upon by compressed air and the piston of which is to be alternately acted upon by compressed air in opposite stroke directions and is guided in a longitudinally displaceable and sealing manner in a cylinder which is circular or deviates from the circular shape, for example is flatly oval, according to standards predetermined by the industry or designations, for example 40, 50, 63, wherein the piston drives a length-variable adjusting member in the stroke direction (X-Y), which, at its piston-remote end, drives, via a toggle linkage mechanism, a force transmission arm which is connected in terms of drive and mounted via a rotary pin, which is pivotable in the clamping head but is otherwise immovable in position and which is led out of the clamping head on one side or on both sides, and which force transmission arm drives a clamping arm or the like pivotably, for example over a pivoting angle of 135 degrees, wherein, while maintaining the torque or the holding torque at the rotary pin and while maintaining the connection dimensions of the clamping head, the clamping head is in each case assigned a cylinder which is smaller in diameter within the industry standard 40, 50, 63 predetermined by the industry, and therefore a smaller pressure-effective piston and therefore a smaller force to be transmitted to the adjusting member, for example the piston rod, and the thereby in each case reduced piston force and the thereby reduced torque or holding torque at the rotary pin is restored to the original or virtually original value of the piston-cylinder unit which is larger within the industry standard by a corresponding increase in the effective lever length (L) of the force transmission arm corresponding to the reduction of the piston force of the piston.
