- the installation further comprises locking means for locking the cross member relative to the posts when said members are engaged on said complementary means.
- the sled's removable sleepers are perfectly locked with respect to the fixed posts and thus the geometrical position of the different parts or elements is perfectly defined, which allows them to be assembled, in particular to weld them together with a large amount of space. precision.
- said members and said means cooperate together by conjugation of forms.
- said locking means comprise a member that can hook onto the cross member and push it towards the post when said members and said means are engaged one inside the other.
- This member can be controlled by a hydraulic cylinder, pneumatic or electric.
- said members or said complementary means comprise a hollow or projecting shape that can engage substantially without play in one another by vertical displacement towards one another.
- These shapes can be projections shaped tip, cone, sphere and complementary recesses in the form of V, frustoconical or spheroidal cavity.
- said removable crosspieces are placed on the sled, such that when they are locked to the posts, after lowering of the lifting table, these crosspieces support all the parts in a predetermined geometrical position, some by compared to others.
- Each crossmember can be made in one piece or consist of two separate elements removably attached to the sled.
- FIG. 4 is a front view of an installation for setting the geometry of underbody elements of motor vehicle bodies, the sled supporting these elements being situated above the fixed posts of the geometry station,
- FIG. 5 is a view similar to FIG. 4 showing the removable sleepers of the sled in position on the posts,
- FIG. 6 is a partial detail view, showing the end of a cross member in position relative to a reference hole of a base member and locked relative to a fixed post,
- FIG. 7 shows in perspective a variant of the device for setting a crosspiece in geometry with respect to a post
- FIG. 8 is a cross-sectional view of the device of FIG. 7,
- Figure 9 shows a cross in two elements.
- Figures 4 and 5 show schematically an installation for the geometry of elements 3 of the underbody of motor vehicles, before welding of these elements.
- each of these elements 3 comprises reference holes 14 and the installation comprises means for defining the geometric position of these reference holes.
- the sled 1 comprises removable crosspieces such as the cross member 12 comprising geometry-forming members 13 whose position corresponds to that of the reference holes 14.
- Each crosspiece 12 is specific to the type of body of a vehicle, which means that for each body, there is a specific set of cross members 12 independent of each other.
- the installation further comprises a station 15 of geometry comprising fixed posts 16 equipped with members 17 on which the specific sleepers 12 of the sled can be fixed at predetermined geometric positions of said sleepers.
- the geometry-forming members 13 carried by the specific cross-members 12 are fingers engaged in the reference holes 14 of the elements transported by the sled 1.
- the sled 1 supporting the elements 3 is transported by a lifting table 6 that can move in a direction parallel to the longitudinal axis of the sled 1.
- the specific sleepers 12 comprise members that can engage complementary means 17 provided on the tops of the posts 16 by lowering the lifting table 6.
- the installation further comprises locking means for locking together the crosspiece 12 with respect to the posts 16 when said members of the crossmember are engaged on said complementary means 17.
- said members and said means cooperate together by conjugation of forms.
- a hole 18 made at the end of the specific cross-member 12 is engaged on a point 17 projecting upwards from the top from the post 16.
- the hole 18 and the tip 17 may be replaced by other means or complementary members cooperating by cooperation of shapes, such as a sphere and a frustoconical cavity or V-section, the essential is to ensure a geometric position well defined between the post 16 and the cross 12 on the one hand and between the cross member 12 and the element 3 on the other.
