Abstract

Device intended for automatically flanging pieces on a machine bed or supporting table, with a vertical force of up to 1000 daN. The device is characterised by an elastic element 1, an articulated lever 2, a hydraulic jack 3, a central rod 6 with a nut 5, and a support 4 fastened by bolts 7. This device enables the piece to be pressed onto the bed with considerable vertical force, by means of a reduced overall size. This force is permanent and not subject to electrical or hydraulic failure. Implementation is very rapidly effected. The tightening and loosening operations are performed automatically by means of the control of a hydraulic electrovalve (solenoid valve).

Description

DESCRIPTION
La présente invention concerne un dispositif de bridage automatique destiné au blocage des pièces sur la table des machines-outils ou des presses.DESCRIPTION
The present invention relates to an automatic clamping device for locking parts on the table of machine tools or presses.

Ce dispositif est constitué d'un élément élastique (1), realisé par l'assem-
Sage de rondelles élastiques en en acier ou par un tampon en élastomère.This device consists of an elastic element (1), produced by the assembly
Wise of elastic washers in steel or by an elastomer pad.

La force de cet élement est transmis à un levier articulé (2) qui permet de PLaquer la pièce à brider sur la table avec une force verticale pouvant aller jusque 1 tonne.The force of this element is transmitted to an articulated lever (2) which allows PLating the workpiece to be clamped on the table with a vertical force of up to 1 ton.

te desserrage s'effectue par un vérin hydraulique (3), alimenté par la pompe hydraulique de la machine ou de la presse.loosening is carried out by a hydraulic cylinder (3), supplied by the hydraulic pump of the machine or the press.

L'ensemble est monte sur un support (4) et précontraint par l'écrou (5) et la tige (6).The assembly is mounted on a support (4) and prestressed by the nut (5) and the rod (6).

Ce support est fixé sur la talle par des boulons (7). This support is fixed on the tiller by bolts (7).
