Zusammenfassung:	The present invention relates to a pallet positioning device for machine tools, comprising: a pallet base placed on a rotating table; a pallet that fixes a workpiece and is detachably coupled to the pallet base and rotates with the workpiece as the table rotates; a clamping part that selectively clamps or unclamps the pallet base and the pallet; and a positioning part that adjusts the concentricity of the central axis of rotation of the pallet base and the central axis of the pallet when the pallet is clamped to the pallet base. Thus, the present invention can improve processing precision by minimizing rotational imbalance and preventing vibration. 본 발명은 회전하는 테이블에 배치되는 팔레트 베이스; 공작물을 고정하고 상기 팔레트 베이스에 탈부착 가능하게 결합되어 상기 테이블의 회전에 따라 상기 공작물과 함께 회전하는 팔레트; 상기 팔레트 베이스와 상기 팔레트를 선택적으로 클램핑 또는 언클램핑시키는 클램핑부; 및 상기 팔레트 베이스에 상기 팔레트가 클램핑될 때에 상기 팔레트 베이스의 회전 중심축과 상기 팔레트의 중심축의 동심도를 조정하는 포지셔닝부;를 포함하는 공작기계의 팔레트 포지셔닝 장치에 관한 것이다.
