Problems solved by technology

For these reasons, the multifunctional head may represent a higher cost than the actual positioning system
Furthermore, this complexity of the headstocks means that, because they are very heavy, sometimes approaching half a ton, very significantly degrades the performance of the positioning system in terms of accuracy and repeatability

Abstract

The invention relates to a device comprising a robot (1) provided with a head unit (3) having a plurality of single-function modules which perform various consecutive operations on a working point. The robot can take the form of an articulated precision robot, a Cartesian machine, a parallel kinematic robot or the like, and the aforementioned modules can be mounted in the head unit transversely, longitudinally or in a matrix arrangement. The method includes operations comprising drilling, reaming and countersinking according to different diameters, quality control of drills, part thickness checks, application of sealant, selection and supplying of rivets or bolts to be fitted, insertion of rivets or bolts, riveting, riveting plant checks, cleaning, aerodynamic tolerance adjustment and aerodynamic tolerance checks.

Description

technical field [0001] As stated in the title of this specification, the following invention relates to a multifunctional apparatus and method for automatic riveting by numerical control, the essential object of which is to facilitate the riveting of workpieces made of metal, carbon fiber, glass fiber or other materials by And achieve joints where the workpieces have very tight manufacturing tolerances, such as are required in the aerospace industry, although other applications are not excluded. [0002] A further object of the invention is to overcome the limitations of the prior art in such a way that the invention can be used in parallel kinematic machines and Cartesian kinematic systems, so that heavy multifunctional heads are not needed, in order to obtain simpler and more expensive Fewer devices. Background technique [0003] In the manufacture of structures, the way of joining two pieces in order to obtain a single piece from a structural point of view can be realize...
