Magnetic force assistant slide locating mechanism

Abstract

The invention discloses a sliding locating mechanism assisted by magnets, and the mechanism comprises a first platform and a second platform. The first platform is combined with a double-sided rack and two first magnets. The two first magnets are arranged on the two ends of the double-sided rack and provided with first magnetic poles and second magnetic poles, and the first magnetic poles of the two first magnets are arranged oppositely to each other. The second platform is combined with two magnetic gear wheels which are articulated with the two sides of the double-sided rack, and the two magnetic gear wheels are both provided with the first magnetic poles and the second magnetic poles. When a relative sliding motion is acted between the first platform and the second platform, the two magnetic gear wheels are driven to rotate by meshing with the double-sided rack in a rotating way; when the two magnetic gear wheels are rotated to the middle of the double-sided rack, the first magnetic poles of the two magnetic gear wheels repel each other; when the two magnetic gear wheels are rotated to the two ends of the double-sided rack, the second magnetic poles of the two magnetic gear wheels and the first magnetic poles of the first magnets attract each other.

Description

technical field [0001] The invention relates to a sliding positioning mechanism, in particular to a sliding positioning mechanism assisted by magnetic force. Background technique [0002] Looking at the existing non-power-assisted sliding positioning mechanisms, most of them have a relatively movable part and a relatively immovable part, and use the contact force and over-distance force existing in nature such as gravitation, surface tension and magnetic force to guide the relatively movable part. The movement of the part, and through the guidance of the sliding guide assembly, the relative movable part can be slid and positioned to the selected position fully or semi-automatically. [0003] Among them, the gravitational force mostly uses the gravity of the counterweight to guide the movement of the relative movable part. Because driving the movement of the relative movable part usually has to overcome a considerable mechanical friction force, it must usually be combined wit...

[0004] Secondly, for those who utilize surface tension, it is usually to use the surface tension difference between the liquid and the relative fixed member and the relative movable member to pull the movement of the relative movable member. Since the surface tension is usually very small, only Unpowered sliding positioning mechanism suitable for extremely small (such as micron and nanoscale dimensions)
