Abstract: The invention relates to a pressure medium system, in particular a hydraulic system, having a fluid pump for delivering a drive fluid with a certain delivery flow rate and a certain fluid pressure, and having a control unit which switches the fluid pump on or off in order to set a predefined setpoint value of the fluid pressure, wherein the fluid pump exhibits an inertia-induced overrun when switched off, such that during the overrun of the fluid pump, the fluid pressure still rises while the fluid pump has already been switched off. It is proposed that, during the increase of the fluid pressure to the predefined setpoint value, the control unit switches the fluid pump off before the fluid pressure has reached the predefined setpoint value. The invention also includes a corresponding operating method.

Abstract: The invention relates to a rotary module (3, 4) for rotatably positioning a component, in particular in a handling device (1) or a mounting device, including a base part (15) having a mounting option for mounting the rotary module (3, 4) and having a rotary part (16) with a mounting option for mounting the component on the rotary module (3, 4), wherein the rotary part (16) is rotatable relative to the base part (15). It is proposed that the rotary module (3, 4) can be optionally configured for a motorized drive (10, 11, 13, 14) or for a manual drive.

Abstract: A system for machining work pieces includes an assembly stand (1) for holding a work piece (6) and carrying the work piece to successive machining stations, and includes an assembly device or machining station (101) that holds a machining tool and receives the work piece to carry out a machining operation. The assembly stand includes a work piece receiving apparatus (3) mounted on a pallet (2) that has sliding and fixing elements (11) mounted on its underside. Each element (11) includes a bell-shaped flexible suction cup member (13). When pressurized air is applied to the suction cup members, the assembly stand floats on a cushion of air so that it can be easily moved. When vacuum is applied to the suction cup members, the assembly stand is firmly fixed in position on a work table.

Abstract: A hydraulic clamp embedded in a T-slot of a machine tool bolster plate, has a T-slotted piston rod end which fits continuously within the T-slot of the bolster plate. Using a T-configured member secured to the underside of a die shoe, and slid into the T-slot, actuating the hydraulic clamp draws the shoe downward, firmly clamping it against the bolster surface. If, instead of a T-configured member, and I-beam member (in effect, a double T) is used in a die shoe having a T-slotted undersurface, the clamping force is extended over the entire length of the I-beam. The effect is to avoid distortion of the die shoe. In addition to the surface friction attendant to the present distortion-free clamping, positive resistance of sideward displacement of the shoe is provided by the T-slot edges. When the present invention is not employed for clamping, the T-slotted surfaces of the bolster plates are unencumbered and may therefore be used and cleaned in an ordinary manner.
