GRIPPER COMPRISING TWO PIVOTABLE GRIP ARMS HAVING DIFFERENT LEVERAGES

摘要

The invention relates to a gripper (1) comprising two pneumatically activatable and pivotably mounted pincer-shaped grip arms. One of said grip arms is embodied as a master grip arm (2) which is used to exert a leverage on a workpiece to be gripped in order to position the same, said leverage being increased in relation to the second grip arm which is embodied as a slave grip arm (3). The inventive gripper (1) also comprises means for detecting the end positions (19) of the two grip arms.
