ABSTRACT:
Clamping cylinders (8) are built into a pallet (1) for clamping on a machine tool table (2). Tongues (14) are connected to the pistons (10) of the clamping cylinders (8), which tongues project over the bottom surface (6) of the pallet (1) and fit into normal T-slots (15) of a machine tool table (2). The tongues (14) are clamped in the clamping position by cup spring sets (11) in the T-slots (15). To release the pallets the clamping cylinders (8) are loaded with pressure fluid, which is supplied through a hydraulic coupling (18, 27), which is automatically coupled together when a moving rod (3b) engages the pallet (1). The novel system permits the use of pallets (1) for clamping of workpieces to be worked, without need for significant changes in the machine tool table (2) (FIG. 2).
