<P>PROBLEM TO BE SOLVED: To provide a workpiece positioning jig in which each guide rod can be easily positioned without using any tools. <P>SOLUTION: The workpiece positioning jig includes a workpiece placing member 1 on which workpieces are stacked, the plurality of guide rods 2 which can be freely positioned in a radial direction, a synchronous positioning mechanism 20 for radially positioning the each guide rod 2 while synchronizing the each guide rod 2 with one another, and a lock mechanism 40 for locking the each guide rod 2 from moving in the radial direction. The synchronous positioning mechanism 20 is provided with a sun gear positioned at a center of a row of the each guide rod 2, and a planetary gear 23 meshing with the sun gear to support the guide rods 2. The lock mechanism 40 is provided with a screw member 27 positioned at a center of rotation of the planetary gear 23, and an internally threaded member 54 screwed together with the screw member 27. An amount of screwing the screw member 27 with the internally threaded member 54 is changed to pinch and lock the planetary gear 23 between friction members 6, 33 on both sides. <P>COPYRIGHT: (C)2012,JPO&INPIT |
