Abstract

The invention is a micro-rotation platform which is used in precise machine. It includes rotary base, rotary desk and spiral mandril device; the rotary base likes a basin with flat bottom and has a vertical tangent on one side, the basin wall is embedded with at least a couple of magnet, there is magnetism isolating ring on the external wall; there is a tiny protruding desk with a screw at the centre of the bottom; there sets scroll bearing at the centre of the rotary desk, one end of the small axis which is fixed with the axis inner hole has whorls and connects with the screw whorls of rotary base, the rotary base is fixed in the rotary base; there sets a couple of magnets on the side wall of rotary desk, there sets transverse pole on position which has the same distance with the magnets on the external wall, the spiral mandril device is set on the vertical tangent of one side of the rotary base.

Description

technical field [0001] The invention relates to a micro turntable for precision machinery, in particular to a micro turntable for precision machinery used for optoelectronic precision mechanical instruments and meters. Background technique [0002] In the prior art, in the design of precision mechanical movement, a rotating action is usually driven by a spring, such as mechanical clocks and watches. In addition, when the precision mechanical movement requires a limited angle of rotation, twisting is generally used in machinery. Spring, pull reed to drive. Above-mentioned structure, modeling are complicated and not compact. Contents of the invention [0003] The object of the present invention is to propose a completely new type of micro-turn structure, a micro-turntable for precision machinery that uses magnetic materials instead of torsion springs and other components. The micro-turntable for precision machinery has a compact a...
