Gripper

摘要

A gripper (1), in particular a pneumatically actuated gripper, with a housing (2), in which a preferably pneumatically actuable linear drive (6) is formed. The gripper also has first and second gripping jaws (10, 20), which are respectively mounted pivotably in relation to the housing (2) about a pivot axis (D1, D2). The first and second gripping jaws (10, 20) are coupled to the linear drive (6) in such a way that a linear movement produced by the linear drive (6) is respectively converted into a pivoting movement of the first and second gripping jaws (10, 20) in an opening or closing direction of the gripping jaws (10, 20). In order to ensure reliable gripping, the first and second gripping jaws (10, 20) are coupled to one another by way of a synchronizing element (5) in such a way that, when the linear drive (6) is actuated, the pivoting movements of the first and second gripping jaws (10, 20) are synchronized.

主权项

1. A gripper (1) comprising:
a housing (2) in which a linear drive (6) is disposed; a first gripping jaw (10) and a second gripping jaw (20), each mounted on the gripper (1) so as to be pivotable about a rotational axis (D1, D2) relative to the housing (2); a synchronizing element (5) which couples together the first and second gripping jaws (10, 20), the synchronizing element (5) including a circular cylindrical section (5′) and defining a longitudinal axis (L1) which runs parallel to the rotational axes (D1, D2) of the first and second gripping jaws (10,20); and a circularly segmented cut-out (11, 21) formed in the first and second gripping jaws (10, 20) and configured to receive the circular cylindrical section (5′), wherein the first and second gripping jaws (10, 20) are coupled to the linear drive (6) such that a linear movement produced by the linear drive (6) is converted into pivoting movements of the first and second gripping jaws (10, 20) in respective opening directions or closing directions of the first and second gripping jaws (10, 20), wherein the pivoting movements of the first and second gripping jaws (10, 20) are synchronized, wherein the circular cylindrical section (5′) is removably accommodated in the two circularly segmented cut-outs (11, 21) of the gripping jaws (10, 20), and wherein the synchronizing element (5) is configured such that removal of the circular cylindrical section (5′) disables the synchronizing of the two gripper jaws (10, 20) but does not disable the function of the linear movement produced by the linear drive (6) from being converted into the pivoting movements of the first and second gripping jaws (10, 20) in the opening directions or the closing directions of the first and second gripping jaws (10, 20).
