Definitions
- the present invention relates to the field of the assembly of mechanical components in a motor vehicle.
- the present invention relates more particularly to frames for assembling mechanical components in a motor vehicle assembly line.
- OS-POM mechanical components
- assembly frames comprising a frame on which a fixed plate is mounted are known.
- This plate comprises rails and receives mobile plates which can be moved on the rails so as to adapt the assembly frame to the silhouette of the vehicle that one wishes to produce and in particular to its wheelbase.
- the assembly frame also includes supports and elements for holding the mechanical components.
- the design and adjustment phase of the assembly frame is complex and if several different silhouettes of vehicles are produced on the same assembly line, the installation will include as many assembly frames as there are types of silhouettes produced.
- the document CN207606473 describes an example of an assembly frame comprising a frame on which is mounted in a floating manner, on balls, a first plate comprising rails. Specific plates are then mounted, in particular on the first plate.
- the assembly is intended to be able to adapt to different silhouettes of vehicles but always requires an effort to adapt the positioning of the different parts making up the assembly frame with respect to each other with a view to this adaptation.
- the problem of reduction in overall mass is not dealt with.
- the document CN106826021 describes a wheelbase positioning device for a front axle and a rear axle.
- the device includes manual adjustment means to adapt the station to different wheelbases. This solution is not suitable for mounting elements other than the front and rear axles.
- the document CN104493760 describes an assembly frame which supports a front plate and a rear plate. One of the plates is movably mounted on the frame, which allows it to be moved according to the wheelbase of the vehicle.
- a manual locking system makes it possible to position and lock the plate in position.
- the assembly frame proposed in this document is adaptable for vehicles with different wheelbases but is not necessarily adaptable to different vehicle silhouettes. Furthermore, the problem of size, storage and mass of such assembly frames is not addressed.
