Abstract

The invention discloses a direct-drive circular arc movement platform structure, belonging to the technical field of measurement and automation control devices. The direct-drive circular arc movement platform structure comprises a substrate, a stator mechanism, a circular arc movement platform, a mover mechanism, a grating scale and a grating head, wherein the top of the substrate in the length direction takes the shape of a circular arc, the stator mechanism is fixed on the substrate and corresponding to the length direction side of the substrate, the circular arc movement platform is arranged on the substrate, the mover mechanism is fixed on the circular arc movement platform and matched with the stator mechanism, the grating scale is arranged on the stator mechanism, and the grating head is fixed on the mover mechanism and matched with the grating scale. The direct-drive circular arc movement platform structure has the advantages that: the movement precision and movement stability of the circular arc movement platform can be ensured, and the reliability in transverse movement of the circular arc movement platform can also be ensured; the whole structure is simple and compact thus being conducive to manufacture and assembly; a subsequent control algorithm can be simplified due to the cooperation of the grating head and the grating scale so as to satisfy operating requirements on precise detection, precise manufacture and automation control occasion.

Description

technical field

[0001] The invention belongs to the technical field of measurement and automatic control devices, and in particular relates to a direct-drive arc motion platform structure, which uses a direct-drive motor that moves the mover relative to the arc-shaped stator to drive the movement connected with the mover. The platform moves accordingly, and at the same time, the moving platform itself moves laterally relative to the direct-drive motor, so that the moving platform realizes the compound movement of circular arc motion and lateral motion perpendicular to the direction of circular arc motion. Background technique

[0002] High-speed and high-precision motion platforms are widely used in precision testing and automation industries, while arc motion platforms are mainly, but not limited to, designed for applications with a fixed arc radius around a certain point, for example, X The ray intensity of the ray source requires a motion platform that faces the ray sourc...
