Nowadays, it is very common to use the clinching technology (i.e. cold press-joining of two and more materials) to join a washing-machine frame with its components. The stimulus for the automation of the clinching manufacturing process was to unite several hand-used tools into one multifunctional. It was also necessary to eliminate lower quality connections, higher wear, more precisely – more frequent wear of the tools which occurred during manual clinching.
The basis of the workstation is a robot with a clinching tool and a primary indexing rotary table with the possibility of 180° rotation, equipped with two secondary arms, working in all axes. An integral part of the workstation is also a set of 9 adjustable fixtures, which are placed on the secondary arms of the table. The fixtures can be adjusted to a desired production sequence. A total of 49 types of frames and their components can be produced in this way with the help of one universal fully automatic workstation.
