Abstract: A changeover apparatus for changing between workpiece supports for a machining machine. The changeover apparatus has a base frame with a carrier apparatus for the workpiece supports, which are vertically movable by the carrier apparatus, with the result that one of the workpiece supports can be transferred into a working plane in which the workpiece support is moved from the carrier apparatus into the machining machine and guided out therefrom. A lifting apparatus acts between the base frame and the carrier apparatus and by way of which the carrier apparatus can be vertically moved relative to the base frame for one workpiece support to take up a first lifting position or a further lifting position in the working plane. The lifting apparatus contains a slotted guide, which movably actuates the carrier apparatus with the workpiece supports together between the first lifting position and the further lifting position.

Abstract: The invention relates to a force module (20) for generating forces in a highly dynamic manner by assembling a plurality of piezo actuators (1) for connecting to a voltage source. To enable the force module (20) to generate forces in the range of a few 100 kN in a highly dynamic and spatially resolved manner, according to the invention it is proposed that the force module (20) consists of at least two sub-modules (21), each having at least two piezo actuators (1) and their electrical contacting elements, and a controlling and protection module (16) for the piezo actuators (1) in the sub-modules (21), wherein all electric contacting elements of the sub-modules (21) are fed into the controlling and protection module (16).

Abstract: Until now, an orientation pattern has been projected onto the skin by means of lasers. The stringers provided with an adhesive film are then positioned by hand on the skin and fixed by pressure weights. A precision of ±3 mm is thus achieved. The fine positioning takes place by means of comb templates. The templates are set one after the other, pressure weights being removed from the stringers after each setting, so a manual orientation of the stringers is made possible. The weights are then set again. The imprecision is still ±1.4 mm. This procedure is very time-consuming and not precise enough. It is therefore proposed to use a gantry robot with a gripper beam to position the stringers, the gantry robot cooperating with a loading unit and a heating station. The time spent is thus substantially reduced and the precision of the product is decisively increased.
