Title:
CONSTANT VELOCITY RECIPROCATING LINEAR MOVEMENT DEVICE AND OPTICAL FIBER POLISHING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2011/092745
Kind Code:
A1
Abstract:
A reciprocating linear movement device is equipped with a slider drive means (17) which assures the reciprocating movement of a slider (16) which can move along the guide surface (15a) of a guide member (15) having a guide surface (15a) which extends in a first direction. This slider drive means (17) comprises: a drive motor (49); a rotating member (51) which is driven by this drive motor (49) about an axis that intersects with the first direction; an eccentric pin (52) which is provided in a protruding manner to the rotating member (51) parallel to the axis of rotation of this rotating member (51); and a guide groove (53) with which the eccentric pin (52) can slidingly engage, and which is formed on the slider (16) in such a manner so as to extend in a first direction and a second direction which intersects with the axis of rotation of the rotating member (51). The reciprocating linear movement device of the present invention is equipped with a means (58) for controlling the speed of rotation of the rotating member (51) in such a manner that the linear velocity of the slider (16) in the first direction is constant, apart from at the ends of the reciprocal movement.
