INDEXING TOOL HOLDER
Document Type and Number:
Japanese Patent JP2023008312
Kind Code:
A
Abstract:
To provide an indexing tool holder capable of converting linear motion of a polishing tool into a rotation step operation, and automatizing rotation of a prescribed angle of the polishing tool by being attached to an NC machine tool.SOLUTION: An indexing tool holder comprises: drive means in which a linear drive part is stored in an indexing tool holder body, and reciprocating and moving linearly the linear drive part; a linear motion groove in which, there is provided a guide groove on a facing surface of the linear drive part facing the indexing tool holder body, to which a protrusion member is engaged, the protrusion member energized toward the linear drive part from the indexing tool holder body, in which the guide groove has a depth which has a longitudinal direction parallel to the linear direction and which is varied according to the position of an indexing rotation angle; and an inclination groove which has a longitudinal direction in a direction crossing the linear direction, and whose depth is varied, among indexing rotation angles. The linear groove and inclination groove are alternately arranged along a circumferential direction of the linear drive part, and are continuously arranged so as to circulate on the facing surface of the linear drive part in the circumferential direction.SELECTED DRAWING: Figure 2
