Patent ID: 10675700

Abstract:
A quick-change coupling (16), for coupling a device carrier (14) to a carrier unit (12) of a welding cell (11), especially for welding together components for internal combustion engine exhaust systems, includes a first coupling unit (18) to be fixed to a carrier unit (12) and a second coupling unit (20) to be fixed to the device carrier (14). One of the coupling units (18, 20) has a pushing meshing recess (24) and the other of the coupling units (18, 20) has a pushing meshing body (26) that can be inserted into the pushing meshing recess (24) in a direction of pushing (R). A positive-locking positioning device (46) is adjustable between a released state and a positive-locking positioning state. With the pushing meshing body positioned meshing with the pushing meshing recess, the positive-locking positioning device in the positive-locking positioning state holds the pushing meshing body in an operating position.
