A linear guide system, a linear guide device and its control device and control method

摘要

A linear guide system, a linear guide device and its control device and control method, wherein the linear guide device comprises a linear guide rail and a carriage movably mounted on the linear guide rail, and a sealed space is formed between the opposed working surfaces of the linear guide rail and the carriage; the sealed space is filled with a lubricant; and the linear guide device further comprises a spool disposed on either the carriage or the linear guide rail, the spiral axis of the spool being perpendicular to the work surfaces and the lubricant being displaced with a magnetic fluid. Using the current-carrying coil in combination with the magnetic fluid, the damping force between the carriage and the linear guide rail can be actively controlled, and a linear guide device with the present technical solution can realize an adaptive control under many different vibration conditions and the requirements for high accuracy of the linear Lower guide rail.
