English Abstract

A coupling interface (1) for grasping by a robotic end effector comprises a
body (2) and two pairs of fingers (4, 5 and 6, 7) extending
outwardly from opposite sides of the body, each pair of fingers (4, 5 and 6,
7) providing a bifurcation between their inner sides (8, 9 and
10, 11) in the form of an inwardly tapering recess (12, 14). All of the inner
sides of the fingers are bevelled for aligning a complementary
shaped anvil with the tapering recess. The anvil (29) is also provided with a
central, chamfered, "V" shaped recess (48) to engage with the
corners of a square-waisted microfixture interface.

French Abstract

Le dispositif concerne une interface d'assemblage (1) permettant la saisie par l'organe terminal d'un robot. Le dispositif est constitué d'un corps (2) et de deux couples de doigts (4, 5 et 6, 7) dépassant vers l'extérieur du corps au niveau des deux faces opposées du corps. Chaque couple de doigts (4, 5 et 6, 7) constitue une patte d'oie quand on considère leurs faces internes (8, 9 et 10, 11). Le profil de cette patte d'oie est en forme de renfoncement se rétrécissant vers l'intérieur (12, 14). Les faces intérieures des doigts sont biseautées pour faire coïncider une touche fixe de forme complémentaire avec le renfoncement se rétrécissant vers l'intérieur. La touche fixe (29) comporte également en son centre un renfoncement chanfreiné en V (48) qui s'adapte aux coins d'une interface dont le microbâti comporte une gorge à circonférence carrée.
