<p>PROBLEM TO BE SOLVED: To provide a nondirectional spherical excitation fixing device that is changed by electric power for excitation and the type of an exciting steel material and that nondirectionally switches a jig angle by determining an attraction force by the mass of a magnetic field volume.SOLUTION: A conical space is formed in a central part of a sphere center top surface of a spherical electromagnetic excitation part. A through shaft can be freely moved through the space, and arbitrary positioning of a jig angle can be set. A magnetic part of a spherical soft magnetic steel material has a radius of an inverted concave spherical shape, and a jig fixing base using a rigid steel material is attached to its backside.</p> |
