PROBLEM TO BE SOLVED: To cope with a workpiece having different outside diameters by one nest.SOLUTION: A vertical groove 51c1 and a horizontal groove 51c2 are formed at a stage 51, and a V-shaped notch 52b and a plurality of pin insertion holes 52c are formed at a slide 52. The pin insertion holes 52c are formed at positions corresponding to ball valves 101 having different diameters and specifications (ball valves 101 having different outside diameters) one by one by displacing a position of the slide 52 in a length direction. When performing the positioning of the valves, positions of the valves are aligned by adjusting a slide position of the slide 52 in the stage 51 so that the pin insertion hole 52c corresponding to the outside diameter of the desired valve opposes the horizontal groove 51c2, and a pin 53 is inserted into the position-aligned pin insertion hole 52c. By this constitution, a tip of the pin 53 is fit into the horizontal groove 51c2, and the slide position of the slide 52 in the stage 51 is regulated.SELECTED DRAWING: Figure 2 |
