Abstract
An assembly for connecting a measuring head to a measuring robot, the assembly having a flange integral with a supporting member of the measuring robot; isostatic supporting elements interposed between the measuring head and the flange; and a rotary ring nut carried by the flange and movable between an angular position permitting insertion of the head, and an angular position locking the head; the ring nut having elastic elements generating a preload on the isostatic supporting elements; and the isostatic supporting elements defining respective switches of an electric circuit forming part of a safety system for detecting shock on the head.
Claims13
An assembly (5) for connecting a measuring head (1) to a supporting member (3) of a measuring robot (2), of the type comprising:
- a first connecting member (10) integral with said supporting member (3) of said measuring robot (2);
- first supporting means (15) carried by said first connecting member (10);
- a second connecting member (12) integral with said measuring head (1);
- second supporting means (16) carried by said second connecting member (12) and cooperating with said first supporting means (15);
- and
- locking means (14) interposed between said first and said second connecting member (10, 12) to keep said first supporting means (15) and said second supporting means (16) contacting each other;
- characterized in that said first and said second supporting means define a substantially isostatic constraint between said first (10) and said second (12) connecting member;
- said locking means comprising a ring nut (14) carried by one (10) of said first and second connecting members (10, 12) and rotating about a respective axis (A) between a first release position permitting relative movement between said first and said second connecting member along said axis (A) of said ring nut (14), and a second angular lock position;
- said assembly (5) comprising elastic means (36) interposed between said ring nut (14) and said second connecting member (12) in said second angular lock position of said ring nut (14) to generate an elastic load to keep said first and said second supporting means (15, 16) in contact with each other.
