Abstract

A linear guide system, a linear guide device and its control device, and a control method, wherein the linear guide device includes: a linear guide rail and a slider movably arranged on the linear guide rail, and the linear guide rail and the slider A sealing gap is formed between the face-to-face working surfaces; the sealing gap is filled with lubricant; the linear guide device also includes: a coil, which is arranged on one of the slider and the linear guide rail, and the spiral of the coil The axis is perpendicular to the working surface, and the lubricant is doped with magnetic fluid. The damping force between the slider and the linear guide rail can be actively adjusted by using coil energization and magnetic fluid. The linear guide device of this technical solution can meet the adaptive adjustment under various vibration conditions and reduce the high precision of the linear guide rail. Require.

Description

technical field [0001] The invention relates to a linear guiding device, in particular to a linear guiding system, a linear guiding device, a control device and a control method thereof. Background technique [0002] An existing linear guide device includes: a linear guide rail and a slider slidably straddling the linear guide rail. The linear guide device is used to support and guide the load connected to the slider, so that the moving parts can perform high-precision reciprocating linear motion in a given direction. [0003] During operation, the load inevitably causes the linear guide to vibrate. The traditional damping method is: a sealing gap is formed between the linear guide rail and the face-to-face working surfaces of the slider, and an extruded oil film is formed in the sealing gap. When the load vibrates, the slider will vibrate, and the slider will squeeze the extruded oil film, and the extruded oil film will become thinner and form a reverse pressure to offset...
