Abstract
A pallet changer including an arcuate clamp rail adapted to engage and support a pallet slidably, the arcuate clamp rail being provided in a work table in a machining center, and a plurality of arcuate support rails adapted to engage and support pallets slidably, the arcuate support rails being provided on a pallet pool so that they can be indexed to a pallet changing position. The support rail indexed to the pallet changing position completes a circular track for pallet conveyance conjointly with the clamp rail. Further, a swivel arm is disposed for rotation between the work table and the pallet changing position, the swivel arm being provided at both ends thereof with engaging hooks each capable of engaging an engaging block of each pallet disengageably. By the rotation of the swivel arm, two pallets are exchanged simultaneously along the above circular track between the work table and the pallet changing position.
