HIGH LOAD AND HIGH PRECISION POLYGONAL GUIDE, AND PICKER ACTUATOR USING SAME

摘要

The present invention relates to a high load and high precision polygonal guide, and to a picker actuator using same, wherein the polygonal guide includes: an integrated ball cage designed and formed in a polygon and having a plurality of ball receiving holes formed on each side of the polygonal ball cage for receiving balls; a housing having a polygonal through hole for rolling motion such that, after the balls are inserted into the ball receiving holes formed on each side of the polygonal ball cage, the balls cannot escape from the ball receiving holes; and a guide post inserted and fitted inside the polygonal ball cage into which the balls are inserted and fitted, whereby the guide post or the housing reciprocates in a straight line by the rolling motion of the balls.

1. A polygonal guide comprising:
a ball cage formed in a polygon and having a plurality of ball receiving holes formed on each side of the polygonal ball cage for receiving balls; a housing having a polygonal through hole for allowing rolling motion of the balls by the polygonal ball cage where the balls are inserted and fitted into the ball receiving holes; and a guide post inserted and fitted inside the polygonal ball cage into which the balls are inserted and fitted, whereby the housing performs the linear reciprocating motion by the rolling motion of the balls.
