PURPOSE:To promote the improvement of work efficiency forming constitution in small size, by providing a fluid pressure cylinder to be oscillatingly arranged between both pallets on a pallet supporting bed and engaging a point end engaging pawl with an engaged protrusion of either pallet. CONSTITUTION:A table supporting bed 4, which reciprocateably supports a table 3, is arranged between a machining center 2 and a pallet changer 1. While a pallet supporting bed 6, which movably mounts a pair of pallets 5 in a direction of the supporting bed 4, is provided in the pallet changer 1, and a fluid pressure cylinder device 7 is provided to be arranged in the central part of said pallet supporting bed 6. And the fluid pressure cylinder device 7, which oscillates to the left or the right by driving a pair of plungers 33a in a reverse direction to each other of an oscillation device 30 engaging an engaging pawl 16a of the device 7 with an engaged protrusion 17 of the pallet 5, moves the pallet 5 between the table 3 and the pallet changer 1 by extending and contracting a fluid pressure cylinder 9. In this way, work efficiency improves by enabling the pallet changer to be miniaturized. |
