1. Equipment for the fastening of a workpiece (41) on a movable workpiece pallet of a palleting equipment, consisting of several workpiece pallets which are feedable in stepwise manner to the treatment station of a numerically controlled machine tool, wherein the equipment is associated with an independent loading appliance set up outside the palletting device and a clamping unit, which is arranged on a base plate (30), is couplable with the loading appliance and consists of at least one store (12), a filling valve (1), at least one control valve (2, 3, 4, 5) and at least one clamping cylinder (20) connected through at least one connecting duct, characterized thereby, that an hydraulic loading appliance and an hydraulic clamping unit are provided and that the clamping unit displays a first duct branch, which serves for the charging of a supporting cylinder (19) and is equipped with a biassed store (9) and a control valve (2) actuable from the machine tool by an actuating fork (42), and a second duct branch, which serves to the charging of at least one clamping cylinder (20) and is equipped with control valves (3, 4), serving for a preset partial relief and actuable by the actuating fork (42) of the machine tool, with a pressure-limiting valve (16) and a volume-compensating cylinder (18) and with control valves (3, 4, 5), which serve for a reduced preset recharging and are actuable by the actuating fork (42), a second biassed store (12), a second pressure-limiting valve (17) and the volume-compensating cylinder (18). |
