DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention concerns an equipment and a method in vehicle alignment work,
BACKGROUND OF THE INVENTION
From the prior art, devices for alignment of an automobile body are known in which the vehicle is driven onto drive plates, after which the vehicle is fixed to the fastenings on the alignment table by raising the vehicle so that its edges are supported by the fastenings at the skirts. In solutions of this sort, the lifting member is fitted to act between the drive plate and the vehicle, and the vehicle must be driven precisely to the location determined by the skirt fastenings. The solution of this sort does not include means for fixing the drive plates. Thus, when a vehicle is driven onto the drive plates, the plates tend to move.
SUMMARY OF THE INVENTION
In the present application, a novel solution of equipment is described in which the problems involved in the prior art are avoided. An inexpensive and advantageous unit of equipment has been formed, in which the drive plates for the vehicle are fixed to the base frame of the alignment equipment and in which solution of equipment the alignment table is guided by means of vertical guide means so as to fix the alignment table to the vehicle by means of its skirt fastenings. The lifting work itself takes place favorably by means of a mobile garage jack or equivalent. The alignment table is kept in its place in the alignment work position by locking the vertical guides.
In the method in accordance with the invention, the vehicle is first driven onto the drive plates, after which the alignment table is raised, for example, by means of a garage jack displaceable on wheels or equivalent. In the method in accordance with the invention, vertical guides are used for guiding the alignment table. By means of the vertical guides, the movements of raising and lowering of the alignment table are controlled, and the alignment table is locked in the desired height position. By using a garage jack or equivalent, one side of the alignment table is raised first, after which the raised side of the alignment table is locked by means of a cotter at a height of, for example, 200 mm. After this, the garage jack is moved to the other side of the alignment table, and corresponding raising is carried out, after which the guides at that side are locked by engaging the locking cotters. In the solution of the present invention, the alignment table is connected with the base frame of the equipment by means of guide pans, preferably telescopic guide parts, which base frame of the equipment rests on the floor of the workshop. The equipment includes fastening means for fastening the drive plates detachably to said base frame.
The equipment in accordance with the invention in the work of alignment of a vehicle is mainly characterized in that, between the alignment table and the base frame, there are vertical guides, which are connected with the alignment table, on one hand, and with the base frame, on the other hand, and whose function is to guide the movements of raising and lowering of the alignment table and whose function is further to support the alignment table and to keep it at the desired working level.
The method in accordance with the invention in vehicle alignment work is mainly characterized in that, in the method, the alignment table is guided by means of vertical guides fitted between the alignment table and the base frame, and that, in the method, first one side of the alignment table is raised, e.g., by means of a garage jack into contact with the vehicle, and after this the garage jack is shifted to the other side of the alignment table, and the other side of the alignment table is raised to the level corresponding to the level of the first side, and after this the guides are locked by means of lateral cotters at that level. Finally, the skirt fastenings are fixed to the vehicle, after which, as the vertical guides have been locked, the drive plates are removed.
