Abstract
The present invention relates to an oblique-driven platform structure, comprising: a base, a first rail, a screw, a first sliding block, a second sliding block, an oblique slide rod, at least one second rail, at least one third sliding block, a work platform, and a motor. There is a trigonometric relation between the oblique slide rod, the screw and the second rail, and an oblique drive angle is formed between the oblique slide rod and the screw; Therefore, with the change of the stroke position of the screw, the displacement resolution of the work platform can still kept the same value when the work platform is driven. Moreover, the displacement of the screw stroke can be proportionally transformed to the feed rate of the work platform through the trigonometric relation, such that the driven work platform can get an extremely high displacement resolution without using any high-level servo motor.
