CONNECTION ARRANGEMENT FOR A HAND-GUIDED MACHINE TOOL AND HAND-GUIDED MACHINE TOOL

摘要

The invention relates to a connection arrangement (10) for connecting a processing head (202) and another machine module (204) of a machine tool (200), in particular a surface processing machine (200), wherein the connection arrangement (10) comprises at least two connection parts (14, 16, 19) arranged successively along a longitudinal axis (12), each having a connection section (20, 22), via which the connection parts (14, 16, 18) can be connected to one another, wherein the connection sections (20, 22) outwardly border a respective inner cross-section (24, 26), wherein, in terms of facilitating the handling with simple constructive means, the connection arrangement is designed and developed in such a way that an electrical plug connector (28, 30), a mechanical clamping element (32, 34) and a connection opening (38, 38) to a flow channel (40, 42) formed in the respective connection part (14, 16, 18) are provided within the respective cross-section (24, 26) in such a way that, when putting together the connection sections (20, 22), the clamping elements (32, 34) engage behind one another and the plug connectors (28, 30) and/or the connection openings (36, 38) are each connected to one another. The invention also relates to machine tool (200) comprising a connection arrangement (10) of this type and an extension piece (16) for a connection arrangement of this type.
