Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] The present invention is a distributed blade-shaped rotating flexible hinge, which is centered on the axis of the cylinder on the cylinder, and is integrated with a through hole 104, a first reed 11 and a second reed by using a precision wire cutting machine tool. 12. The third reed 13, the fourth reed 14, the fifth reed 15, the sixth reed 16, the first inner arm 21, the second inner arm 22, the third inner arm 23, and the outer ring 1 There are A mounting hole 101, B mounting hole 102, and C mounting hole 103; the first reed 11 and the second reed 12 constitute the first pair of leaf reeds; the third reed 13 and the fourth reed 14 constitute the second Pair of leaf-shaped reeds; the fifth reed 15 and the sixth reed 16 form a third pair of leaf-shaped reeds. Between the first inner arm 21 and the second inner arm 22 is a first pair of ...

Abstract

The distributive leaf shaped rotary flexible hinge is manufactured with one cylinder and through integral machining in a linear cutting machine, and has one through hole, three pairs of leaf shaped reeds, three inner arms, and three outer installation holes. The present invention has symmetrically distributed flexibility design of curved reeds, high axial rigidity and radial rigidity, increased rotation range and small rotation axis drift. As one kind of excellent rotary flexible hinge with great deformation, the present invention is suitable for use in great stroke precise control mechanism.

Description

technical field [0001] The present invention relates to a flexible hinge, more particularly to a distributed blade-shaped rotating flexible hinge, and the international patent classification belongs to F16C11 / 00. Background technique [0002] Flexible hinge refers to a kinematic pair structure that uses elastic deformation of materials to generate relative motion under the action of external force or moment, which is very different from the structure of traditional rigid kinematic pairs. A flexible hinge is a typical flexible element in a flexible mechanism. Compared with traditional rigid hinges (mechanisms), flexible hinges and flexible mechanisms have many advantages: (1) can be integrated (or integrated) design and processing, so it can simplify the structure, reduce volume and weight, and avoid assembly; (2) There is no gap and friction, and high-precision movement can be realized; (3) It is free from wear and long life; (4) It is free from lubrication and pollution; (...
