  • the invention further relates to a method for developing a support arm for a tool, which is characterized in that a measuring device of type described above with its installation element attached to a base which is at the later location of the support arm to be developed, and that the tool in question on the tool holder of the measuring device is assembled, whereby the order of these steps is not important. After that, the tool is placed in the place of use Work position brought, and the adjustable joints of the measuring device locked in the positions assumed here. These locked positions of the joints are finally read, and with the help of the Data becomes a regarding the position of the installation element and the tool holder corresponding support arm manufactured.
  • the advantage of such a method is that the tool is stable in his working position can be brought, and that almost at the same time quantified by the joints of the measuring device, the working position relative to the base is so that the desired one can be readjusted and tried again can produce individual support arm.
  • the one to be produced made of support arm segments which are firmly connected at an angle and an installation element for attachment to the base and a tool holder for attaching the tool, the lengths and relative angles of these parts the lengths and angles at the corresponding ones Correspond to parts of the measuring device.
  • the lengths are from Arm segments and the relative angles in the measuring device an immediate Correspondence in the support arm to be manufactured, so that the implementation of the Measuring device for the support arm is particularly simple and the support arm is very stable becomes.

  • the Gripper 12 is intended in the position shown relative to a base, for example relative to a machine frame.
  • a distance bridging, individually adapted support arm to develop what according to State of the art is relatively time-consuming and costly due to an iterative Adaptation process happens.
  • the Measuring device 10 shown in Figure 1 used.
  • the measuring device 10 first contains an installation element 3, which on the Base 1 can be attached.
