Machining center equipped with device for mounting on a clamp parts or profiles to be worked

A machining center comprising:

• a device for mounting on a clamp, parts or profiles, to be worked or which have been worked;
• a supporting frame for supporting a turntable with two or more stepped positions or placements or workstations;
• a loading basket and an unloading basket with multiple receptacles;
• a robot with an anthropomorphic wrist for the loading/unloading of said parts or profiles to be worked and of said parts or profiles which have been worked from said loading basket to said unloading basket,
• wherein said robot is configured to remove or to associate, with each one of said two or more stepped positions or placements or workstations, said parts or said profiles to be worked and which have been worked at a plurality of fixed RPS or fixed reference points and mobile mechanical components, according to a single positioning that is adapted to allow access by machining devices to any zone in a space wherein said parts or of said profiles to be worked are located, by modifying only a condition that said two or more stepped positions or placements or workstations are in,
• said fixed reference points and said mobile mechanical components being adapted to achieve a leveling-off of said parts or of said profiles to be worked according to a three-dimensional Cartesian reference system,
• wherein a grip hand is mounted on said robot wrist and is equipped with suckers or pneumatic grippers the function of which is to pick up said part or said profile to be worked from one of said loading baskets, position it in a desired stepped position or placement or workstation, exit from said stepped position or said placement or said workstation in order to allow the rotation of said turntable, and reenter in order to pick up said worked part or profile and set it down in one of said unloading baskets, said grip hand is configured to remove or to associate, with each one of said two or more stepped positions or placements or workstations, said parts or said profiles to be worked and which have been worked at said reference points by way of said mobile mechanical components, said reference points and said mobile mechanical components being adapted to make it possible to support and clamp, enable the insertion and the unloading, and enable the necessary machining operations and measurements, of said parts or said profiles to be worked and which have been worked in all directions,
• wherein said reference points are positioned in a plate which is integral with said turntable, and are adapted to interact with said mobile mechanical components which are capable of positioning said parts or said profiles to be worked in said fixed reference points,
• wherein said plate has a pair of first, lower, fixed reference points, a pair of second, front, fixed reference points and a third, front, fixed reference point, and a fourth, lateral, fixed reference point, said second, front, fixed reference points and said third, front, fixed reference point protruding from fixed front jaws of said first clamps, said fixed front jaws facing toward mobile rear jaws.
