Abstract (en)
The mechanism (2) consists of a thrust member (20), fixings (22), and a locking assembly (26) for one portion (21) of the thrust member against the workpiece (13). The mechanism incorporates a regulator (25) for the distance of another portion of the thrust member from the table (1), actuated by the locking mechanism so that one surface of the thrust member, e.g. the under-surface (21a) of a projection (21), is always parallel to the table. The locking assembly comprises a threaded rod (24) inside a bush (26a) with locking elements (26b,c), while the regulator has a second threaded rod with its upper end able to rotate freely in a cylindrical cavity (20b) in the thrust member while engaging with a threaded hole (23b) in another component (23) of the fastening mechanism.
Abstract (fr)
La bride de fixation (2) permet de fixer de manière efficace, soit une pièce à usiner (13) sur une table porte-pièce (1), soit un outil sur une table porte-outil d<IMAGE>une machine-outil,la surface dappui (21a) dun corps dappui (20) de ladite bride restant toujours parallèle à la surface dappui (10) de la table de la machine-outil. Pour ceci, des moyens de transmission mécaniques (3) transmettent le mouvement de rotation dune douille (26a) participant au serrage de la bride à un axe fileté (25) disposé vers larrière du corps dappui (20), cet axe fileté (25) servant au réglage du parallélisme dudit corps dappui relativement à la surface dappui (10) de la table. Le rapport de transmission et le sens dactionnement de laxe fileté (25) sont tels que le corps dappui (20) reste toujours parallèle à la surface dappui (10) de la table. <IMAGE>
