Abstract: The invention is concerned with a toggle clamp construction comprising an actuator cylinder including a linearly guided piston rod. The piston rod engages a header of the construction arranged on one end or the actuator cylinder where it is connected, via an adjusting mechanism, to a clamp arm pivotally located on the header. The header is provided with at least one engaging hole; an extension is disposed an the piston rod. For selectively fixing the opening angle which is to be taken by the clamp arm after opening the clamp mechanism, a support element for a stop is detachably inserted in the engaging hole. The said stop protrudes into the path of adjustment of the extension of the piston rod, thereby determining the opening angle.

Abstract: The invention is concerned with a closure clamp, comprising a carrier element (1) provided with a bearing (2), and a clamping lever (3) pivotable thereto, wherein one end (31) thereof is connected to the bearing (2) while the second end thereof includes a handle (32). To that effect, a pivotally arranged clamping element (5) is disposed on the clamping lever (3) between the bearing (2) and the handle (32) to detachably connect a locking element (6) provided on the W side of the bearing (2) facing away from the handle, to the carrier element (1). Provision is made according to the invention that, for swivelling the clamping element (5), the same is provided, on the side facing the handle, with a hand-operated lever (7).

Abstract: The invention is related to a supporting structure, especially for attachment to a robot arm and for securing tools, such as clamping, gripping and suction devices or other equipment such as valves, sensors and the like. The supporting structure is formed of not less than two shaped bars and of at least one clamping member. The clamping member conforms to the profile of the bars and is formed of at least two parts, and the shaped bars are provided with at last one undercut groove, with an adjusting strip being arranged within the said groove and being displaceable and firmly clamped therein. Provided both within the clamping member and within the adjusting strip, for insertion of an adjusting pin, are adjusting ports adapted to be placed in registry by a relative displacement of the adjusting strip and the clamping member, with the said adjusting ports being of identical diameters.

Abstract: A clamping device, more particularly a toggle lever clamping device is devised for clamping workpieces and comprises an actuator cylinder (3) with a mounting head (23), said mounting head protruding from the piston rod and being provided with the control mechanism for the clamping arm (24) which is linked to said mounting head and, furthermore, two pressure medium supply lines and sensors for the final position with connecting lines. A positioning rod (5), provided with positioning elements (4), is arranged on the free end (1) of, and parallel to, the piston rod (2) and directed toward the actuator cylinder (3). The positioning path (W) of the positioning elements (4) extends within the region of the actuator cylinder (3). At least two sensors (6, 6') for the end position are located in the region of the positioning path (W).

Abstract: The invention provides a device for actuating a clamping tool means by fluid pressure and for monitoring the fluid pressure, which comprises a carrier for a workpiece and the clamping tool means, a first mounting element on the carrier, a second mounting element, and means for detachably coupling the second mounting element to the first mounting element. A pressure fluid conduit system is connected to a fluid pressure generator and includes a first fluid pressure conduit in the first mounting element, a second fluid pressure conduit in the second mounting element, detachable connections between the first and second fluid pressure conduits, the detachable connection in the first fluid pressure conduit including a check valve retaining the fluid pressure in the first fluid pressure conduit when the second fluid pressure conduit is detached, and a third fluid pressure conduit connecting the first fluid pressure conduit to the clamping tool means.
