DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an arrangement for prestressed assembly of machine- and base-modules capable of attachment to and dismantling from one another in parting planes located at right angles or parallel to one another. More precisely, the parting planes are located in a cartesian (right angled, three-dimensional) system of co-ordinates in such a way as to be parallel to two of the axes while intersecting the third axis at points determined by a module length laid down for the system of co-ordinates. By way of explanation it may be said that with a uniformly constructed brick wall the parting planes between the bricks are located in this manner. The present arrangement for assembling modules is however not restricted to modules of uniform parallel-epipedic form. The distance between opposite parting planes of a module may vary by discrete steps corresponding to the said module length. Furthermore, module faces not used for assembly or assembled with another machine component according to a different principle may be of any form whatsoever. The problem solved or facilitated by the present invention consists, generally speaking, in being able to produce machines and machine systems in user-orientated designs, at acceptable costs, within short production times and in such a way as to permit conversion at a later date. This problem often arises when designing major industrial plant and systems, but also with minor machine systems such as special machine tools.
It has long been known that construction kits consisting of machine units and base components in the shape of modules meet the requirements for solving the said problem. However a number of more detailed conditions must also be satisfied.
It must be possible to combine the modules with one another in a number of different relative positions so as to enable variations in the structure of the end product to be achieved simply by assembling the modules in different ways. This makes it possible to construct different user-orientated product models using a minimum number of different modules. This enables long series of individual module types and, as a result, low manufacturing costs as well as storage of finished modules with a view to short end product fabrication times.
Furthermore, the modules must be capable of being dismantled in a simple way. This corresponds to the said requirement of convertibility at a future date.
In addition, the rule applies with mechanical constructions that a number of function-dependent conditions must be satisfied. As regards the jointing arrangements between the modules stringent requirements frequently apply inter alia in respect of strength, rigidity and accuracy.
The said arrangement of parting planes between modules, on which the present invention is based, offers considerable possibilities of combination in different positions. Apart from the said example of brick assemblies this is also illustrated by model construction kits for children such as Fischer Geometric. However, no known jointing arrangement has been shown to satisfy the requirements in respect of mechanical constructions and the requirement of suitability for dismantling without at the same time considerably reducing the degree to which units can be combined. For instance, flanged connections entail projecting flanges which make assembly in different angular positions more difficult or impossible. Stud connections and dovetail connections entail male and female sides, which also reduces the degree to which combinations are possible. With the arrangement designed for prestressed assembly of machine- and base-modules, laid out in accordance with the invention and characterised in the patent claims, these difficulties are avoided entirely.
Other characteristics and advantages of the present arrangement appear from the following specification of a number of embodiments of the said arrangement presented with reference to the attached drawings. In the different figures units which are identical or have identical functions are, wherever possible, identi
