Device with components connected via a connection interface and method for connecting components

A method for connecting a first subassembly to a second subassembly in a device, in particular in a device for the handling and/or processing of parts, wherein the first and second subassembly are connected by means of a connection interface by virtue of a first contact section of the first subassembly being plugged and/or pressed in a connecting direction onto a second contact section of the second subassembly in an orientation that is specified relative to the second contact section, wherein the connection interface comprises firstly an electrical interface for the transmission of electrical power and/or of communication signals between the first and the second subassembly and secondly a fluid interface for the transport of fluid between the first and the second subassembly, wherein

• a first and a second contact section are used which are configured such that, for multiple possible orientations of the first contact section with respect to the second contact section, which orientations differ from one another exclusively in terms of a rotation of the first contact section by a specified angle about a rotation axis running in the connecting direction, the connection interface results when the first contact section is plugged or pressed in the connecting direction onto the second contact section in the respective possible orientation, wherein one of the possible orientations is used as the specified orientation, wherein the contact sections are fastened to one another by a fastening means comprising a main body, which annularly encircles the rotation axis, and comprising in each case multiple first and second webs which project from the main body, wherein the fastening is performed by way of a rotation of the fastening means from a release position into a fastening position, wherein, in the fastening position, the first webs engage over in each case one support section of the first contact section and a respective web surface of the respective first web engages on a support surface of said support section, which support surface is averted from the second contact section, and the second webs engage over in each case one support section of the second contact section and a respective web surface of the respective second web engages on a support surface of said support section, which support surface is averted from the first contact section, wherein the respective support sections of the first and of the second contact section are spaced apart from one another in a circumferential direction of the rotation axis by intermediate spaces, wherein, in the release position, the web surfaces of the first and of the second webs are arranged in the intermediate spaces as viewed perpendicular to the rotation axis.

A device, in particular for the handling and/or processing of parts, having a first and a second subassembly which are separably connected or connectable by means of a connection interface, wherein the connection interface results from a first contact section of the first subassembly being plugged and/or pressed in a connecting direction onto a second contact section of the second subassembly in a first orientation that is specified relative to the second contact section, wherein the connection interface comprises firstly an electrical interface for the transmission of electrical power and/or of communication signals between the first and the second subassembly and secondly a fluid interface for the transport of fluid between the first and the second subassembly, wherein the first and the second contact section are configured such that the connection interface also results if the first contact section is plugged or pressed in the connecting direction onto the second contact section in at least one further orientation, wherein the respective further orientation corresponds to the first orientation aside from a rotation of the first contact section by a respective specified angle about a rotation axis running in the connecting direction, wherein at least one of the subassemblies comprises an actuator that is configured to move a component that is mounted so as to be movable with respect to the contact section of said subassembly, wherein a direction of the movement and/or of a rotation or pivot axis of the movement and/or a movement path of the component is dependent on whether the first contact section has been plugged and/or pressed in the or the further orientation onto the second contact section, and wherein the actuator is a pneumatic or hydraulic actuator or at least one of the subassemblies comprises a pneumatic or hydraulic actuator, wherein the device is configured such that operating fluid used for the operation of the pneumatic or hydraulic actuator is conducted to said subassembly and/or discharged from said subassembly via the fluid connection.
