Method for mounting on a clamp workpieces in processing centers

A method for mounting on a clamp parts or profiles to be worked or already worked in a processing center provided with a supporting frame for a turntable with two or more stepped positions or stands or machining stations, comprising a robot, which is anthropomorphic on a wrist, for loading or unloading said parts or profiles to be worked and of subsequently worked parts or profiles, from a loading basket toward an unloading basket with multiple receptacles, comprising the following steps:

• inserting said part or profile to be worked, by means of said robot, in a region arranged below at least one first open clamp that is present in one of said stands or stepped positions or machining stations;
• resting said part or profile to be worked on at least one first lower fixed reference provided on a fixed front jaw of said at least one first open clamp;
• resting said part or profile to be worked on a second and/or third front fixed reference present on said fixed front jaw of said at least one first open clamp;
• resting said part or profile to be worked on at least one fourth lateral fixed reference present on one side of said fixed front jaw of said at least one first open clamp;
• lateral closing of said part or profile to be worked by means of a first movable presser associated with said stand;
• upper closing of said part or profile to be worked by means of at least one second presser associated with said stand;
• front closing of said part or profile to be worked by means of the movement of the second jaw of said at least one first clamp.
