PROBLEM TO BE SOLVED: To provide a workpiece positioning device facilitated in work for replacing a positioning pin and dispensing with a mechanical clamping mechanism of a workpiece. SOLUTION: The workpiece positioning device for positioning a workpiece W by inserting the positioning pin 6 to a positioning hole Wa of the workpiece W is provided with three claw members 5 for holding the positioning pin 6 in such a state that the positioning pin 6 is projected while exhibiting a magnetic attracting force, and three slide members for moving the three claw members 5 forward and backward in the radial direction in relation to the positioning pin 6. The claw member 5 formed into a circular shape holds the positioning pin 6 in the peripheral surface 5a thereof and magnetically attracts the workpiece 5 at the top surface 5b thereof. A magnetic attracting force of the claw member 5 is adjusted by an exciting means. COPYRIGHT: (C)2008,JPO&INPIT
