Abstract

<B>APERFEIçOAMENTO PARA DISPOSITIVO DE FIXAçãO COMPREENDENDO ALAVANCA ACIONADA POR PISTãO<D> A invenção envolve um dispositivo de fixação (1) destinado a reter uma peça estrutural a ser usinada ou soldada compreendendo uma alavanca (2) montada de modo articulado em torno de um eixo geométrico de rotação relativo a um corpo do dispositivo a ser articulado pelo deslocamento da haste de pistão (6) de um acionador com eixo geométrico longitudinal (ZZ') entre uma primeira posição denominada posição inativa de afrouxamento ou liberação e uma segunda posição (B) denominada posição ativa de fixação, a dita alavanca (2) sendo acoplada à extremidade (8) da haste de pistão (6) via meios de controle e ligação (MC). A invenção é caracterizada por compreender meio de amortecimento (MA) externo ao acionador (7) destinado a absorver os choques causados nas peças móveis de controle e ligação (MC) quando a haste de pistão (6) retornar à sua posição de afrouxamento correspondendo à posição inativa da alavanca de fixação.<B> IMPROVEMENT FOR FIXING DEVICE UNDERSTANDING PISTON-ACTIVATED LEVER <D> The invention involves a fixing device (1) designed to hold a structural part to be machined or welded comprising a lever (2) mounted articulated around a geometric axis of rotation relative to a body of the device to be articulated by the displacement of the piston rod (6) of an actuator with longitudinal geometric axis (ZZ ') between a first position called inactive position of loosening or release and a second position ( B) called the active clamping position, said lever (2) being attached to the end (8) of the piston rod (6) via means of control and connection (MC). The invention is characterized by a means of damping (MA) external to the actuator (7) intended to absorb the shocks caused by the moving control and connection parts (MC) when the piston rod (6) returns to its loosening position corresponding to the inactive position of the clamping lever.
