Title:
BLOCK FOR PRECISION STOCK VICE
Document Type and Number:
Japanese Patent JP2018176357
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To heighten a magnetic flux density on the surface, and to stabilize arrangement of a block body, at a using time; and to lower the magnetic flux density on the surface, and to remove iron powder or cut powder by a waste cloth or by an air gun at a non-using time.SOLUTION: Underside ferromagnetic substances 36A, 36B use the inside of a block body 34 as a main magnetic path. When an external magnetic substance of a precision stock vice or the like is contacted and sucked to the bottom surface 38 side, the atmospheric side having a high magnetic resistance becomes a low-resistant side, and upright-surface ferromagnetic substances 46A, 46B and a connected ferromagnetic substance 82 which are fitted single respectively in a first bottom surface insertion hole 33a and in a second bottom surface insertion hole 33b work as a magnetic path, and the external magnetic substance side of the precision stock vice or the like having a low magnetic resistance works as the main magnetic path.SELECTED DRAWING: Figure 6
