Abstract
A pallet exchanging apparatus for machine tool used for exchanging the pallet loaded with the machined workpieces with the pallet loaded with the workpieces to be machined. The pallet exchanging apparatus has a transmission device for shifting the pallet between a work position on a table of the machine tool and a waiting position for exchanging the pallets. The transmission device is driven either by the movement of the table or the movement of the driving mechanism for the table and is adapted to output the rotational movement. The output of the transmission is used for driving a speed-up device. The speed-up device is adapted to move the pallet linearly with higher speed and larger stroke than those of the linear movement of the table.
