Claims

[Scope of utility model registration request]

A rotary table is supported rotatably around a vertical axis on a frame body on an extension of the sliding direction of the machine table of a machine tool, and pallets are arranged parallel to each other on this rotary table with the diameter line of the rotary table in between. A pair of guide rails that slidably guide the pallet, and a loading/unloading hook that can engage with the pallet, and the pallet is loaded/unloaded between the guide rail and the work table by reciprocating the loading/unloading hook. In the pallet loading/unloading device, a movable table is supported on the frame body so as to be movable in a direction parallel to the sliding direction of the work table, and reciprocating means for reciprocating the movable table is provided, and a reciprocating means is provided on the movable table. A loading/unloading hook that removably engages with the pallet is pivotably supported around a vertical axis, and a restraining pin that can be raised and lowered to restrain the rotation of the loading/unloading hook is provided, and the loading/unloading hook is provided near the retreating end of the movable table. A cam plate is provided that has an engagement groove that engages with the restraint pin and moves the restraint pin up and down as the movable base moves to allow the rotation of the loading/unloading hook, and at the retreating end of the movable base, the loading/unloading hook is connected to the pallet. A pallet loading/unloading device comprising a rotating means for rotating the pallet into and out of engagement with the pallet.
