A double-layer two-phase reactive linear precision adjustment slide table

Abstract

The invention discloses a double-layer double-phase reactive linear precision adjustment sliding table. The double-layer double-phase reactive linear precision adjustment sliding table comprises an inverse phase fixed plate, a linear sliding rail, a normal phase fixed plate and a movable plate, wherein the inverse phase fixed plate and the normal phase fixed plate are tooth-shaped plates made of silicon steel sheets, and are respectively wound by a plurality of coils; the coils comprise A phase coils and B phase coils; the polarities of corresponding N poles and S poles of the coils with the same phase on the inverse phase fixed plate and the normal phase fixed plate are opposite; the tooth shapes of the coils with the same phase are aligned; the distances of any coils and adjacent coils are respectively 3 / 2 tooth pitches and 1 / 2 tooth pitches; the movable plate is arranged between the inverse phase fixed plate and the normal phase fixed plate; the linear sliding rail is arranged below the movable plate; and the movable plate and the linear sliding rail form a sliding pair. The double-layer double-phase reactive linear precision adjustment sliding table can realize high-precision axial adjustment of the sliding table, is simple in control mode, and is compact in appearance.

Description

technical field [0001] The invention relates to a linear precision adjustment slide table, in particular to a double-layer two-phase reaction type linear precision adjustment slide table. Background technique [0002] Nowadays, the linear adjustment mechanism mostly adopts the screw nut mechanism. The motor drives the screw to rotate, and the nut converts the rotary motion into linear motion. The return error caused by the clearance of the trapezoidal screw, in order to solve the return error, the ball screw was born. Although the ball screw can solve the problem of return error, when the equipment is used for a certain period of time, the ball screw will also produce a gap, which will affect the adjustment accuracy; in addition, due to the complex process of the ball screw, it needs to be used with a relatively large motor , not suitable for small precision slides. Contents of the invention [0003] In order to solve the above problems, the present invention provides a ...
