Title:
BALL SCREW NUT POLISHING METHOD AND ITS DEVICE
Document Type and Number:
Japanese Patent JP2018058145
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a ball screw nut polishing method by which a rotation axial line of a pressure-welding roll is arranged while inclining in response to a lead angle of a ball groove, a polishing tape moves in conformity to a lead of the ball groove by the movement of the polishing tape which is synchronized with a rotational speed of a nut, the polishing tape surely pressure-contacts with the ball groove, and the ball groove can be surely polished by the polishing tape.SOLUTION: A ball screw nut polishing device comprises: a tape pressure-contact mechanism E for making a bypass polishing part Dof a polishing tape pressure-contact M with a ball groove K of a nut W at an external peripheral face of a pressure-contacting roll D; an inclination mechanism F for arranging a rotation axial line O of the pressure-contacting roll so as to be tiltable in response to a lead angle θ of the ball groove; a tape moving mechanism G for moving a polishing tape to an axial line Wdirection of the nut; and speed synchronization means H for making a rotational speed Q of the nut synchronized with a movement speed V of the polishing tape in response to a lead L of the ball groove.SELECTED DRAWING: Figure 5
