Title
(EN) WORKPIECE CLAMP
(FR) APPAREIL DE PREHENSION DE PIECE A USINER
Abstract
(EN)
A workpiece clamp has a mounting block (2, 3, 31) for mounting the clamp to a workpiece support carriage, a projecting support member (4) carrying a lower jaw (11) at its free end, an elongate upper jaw (14) pivoted intermediate its ends on the support member (4) and arranged at one end to cooperate with the lower jaw (11) to clamp a workpiece, the other end of the upper jaw (14) carrying a cylinder assembly (17) operative to cause rotation of the upper jaw (14) relative to its pivot (7) to clamp a workpiece, a datum face (23) between the jaws which a workpiece abuts during clamping, resilient means (9 and 10) restricting the pivotal movement of the upper jaw (14) and spring-biassed sensing means (24, 25, 26, 27) associated with the datum face to identify whether or not the workpiece is in abutment with the datum face.
(FR)
Un appareil de prehension de piece a usiner possede un bloc de montage (2, 3, 31) pour monter l'appareil sur un chariot de support d'une piece a usiner, un organe de support de projection (4) portant une machoire inferieure (11) a son extremite libre, une machoire superieure allongee (14) pivotant entre ses extremites sur l'organe de support (4) et disposee a une extremite pour cooperer avec la machoire inferieure (11) pour tenir une piece a usiner, l'autre extremite de la machoire superieure (14) portant un assemblage a cylindre (17) fonctionnant pour effectuer la rotation de la machoire superieure (14) par rapport a son pivot (7) pour fixer une piece a usiner, une face de reperage (23) entre les machoires contre laquelle s'appuie une piece a usiner pendant sa fixation, des moyens elastiques (9 et 10) limitant le mouvement de pivotement de la machoire superieure (14) et des moyens de detection armes avec un ressort (24, 25, 26, 27) associes a la face de reperage pour indiquer si oui ou non la piece a usiner est en appui sur la face de reperage.
