A fine positioning device

Abstract

The utility model relates to a kind of precision positioning device, belong to the technical field of circulation frock, including suction head fixed plate, several suction head components are evenly equipped on suction head fixed plate, several suction head components are inserted with top rod, the upper end of top rod is connected with first driving device, the lower of suction head fixed plate is equipped with precision positioning plate, several suction head components pass through precision positioning plate, first through-hole that can accommodate several suction head components pass through is equipped on precision positioning plate, precision positioning plate is connected with second driving device, the utility model is driven top rod up and down movement by the reciprocating motion of cylinder up and down, to realize the magnetic attraction and separation of magnetic product and suction head, complete the taking and placing action of magnetic product;The reciprocating motion of pen-shaped cylinder drives precision positioning plate up and down movement, the positioning action of magnetic product is realized by the friction force between precision positioning plate and magnetic product, the multiple positioning action of product can be realized by the reciprocating motion frequency of pen-shaped cylinder, to realize the reliable positioning of product.
