Apparatus and method for assembling workpieces

Illustrated and described is an assembling apparatus (3) for assembling workpieces. The object of the present invention to provide an assembling apparatus which allows at the same time to position a workpiece in relation to another workpiece and to adjust the shape of said workpiece in a possibly easy and fast manner and with a possibly high preciseness is solved by an assembling apparatus (3) comprising a support structure assembly (13) such as a frame structure which is provided with a coupling portion (19) for coupling the support structure assembly (13) to a positioning device (5) such as an industrial robot, and a plurality of fixing members (15) capable of fixing a workpiece (27), wherein each fixing member (15) is connected with the support structure assembly (13) via a linear actuator (17) a first end (29) of which being mounted on the support structure assembly (13) and a second end (31) of which carrying the fixing member (15), wherein the linear actuator (17) is adapted to be controlled such that the distance between the first and the second end (29, 31) may be adjusted by a linear movement.
