Title: Fitting device for automatically joining assemblies to the body of a motor vehicle from below
Inventor: SCHUPP GERHARD
IPC: B62D65/02
Filed: 1989-03-02
Abstract: The invention is concerned with a fitting device for automatically joining components or similar assemblies (14) to the underside of the bodies (1) of motor vehicles. For this purpose, the assemblies (14) are arranged on receptacle plates (12) so as to be centred but capable of being lifted off, the said receptacle plates (12) themselves being mounted on a fitting frame (9) so as to be vertically movable and capable of yielding laterally in a floating fashion in the raised position. Upright centring pins (17, 24) of the receptacle plates (12) engage through the assemblies (14). The protruding part (24) of the centring pins (17) tapers in its end region and is intended to dip into an associated centring hole of the vehicle body (1) as the fitting frame (9) lifts up. Since, in this phase, the receptacle plate (12) is mounted on the fitting frame (9) in a floating fashion, the assembly (14) which is located thereon automatically moves into a position which is suitable for joining and in which an automatic screwing process can be performed. <IMAGE>
