<p>Arm arrangement for a manipulator has a support arrangement with at least two lateral support plates, in which a drive is fastened on one and the drive shaft passes through the plate. A second drive coaxial to the first is attached to one of the other plates with the shaft passing through the plate. A first arm has two side plates, of which one is fixed on the drive shaft of the first drive and the other can rotate over the shaft of the second drive. A second arm pivots on the other end of the side plates. A first chain wheel is fastened on the drive shaft of the second drive and a second chain wheel is fastened on the swivel pin for connecting the first arm and the second arm. An endless chain connects the wheels and a gripping device is provided at the tip of the second arm for a workpiece. Manipulation of workpieces in forging, casting etc. with predictable geometric position of the workpiece is achieved.</p> |
