ABSTRACT:
A system for controlling the jaws of a self-centering pallet which can be moved between pallet supports at the loading and unloading station and the working station of a machine tool includes an external hydraulic control circuit with a pair of ducts each of which communicates, through a respective connector device, with a pair of supply and discharge ducts of a double-acting cylinder incorporated in the pallet to control the jaws. Each connecting device includes interengageable connectors projecting from the mutually-facing surfaces of the pallet and the pallet support, a non-return valve located upstream of the connector on the pallet, and a rod passing through the connector on the pallet support and able to advance and open the non-return valve under the action of a piston subject to a pilot pressure. The connector on the pallet support is movable axially and connected to a valve which is held open against the action of resilient member when the connector on the pallet support engages the connector on the pallet during the superpositioning of the pallet on the pallet support.
