A flexible Hooker hinge

Abstract

The invention relates to a flexible Hookee hinge, comprising a hinge main body and a first connecting shaft and a second connecting shaft installed on the hinge main body, the hinge main body is a closed structure formed by connecting shafts end to end, and the closed structure has For several bending parts, at least five sets of cutouts are formed on the shaft, and the axes of the at least five sets of cutouts intersect at the same point, and each set includes two cutouts distributed symmetrically in a mirror image. The structure of the present invention can realize all the functions of the traditional Hooke hinge, including independent rotational motion along two vertical axes passing through the same point, and has better mechanical and dynamic properties, higher motion precision, and more convenient assembly. Reliable and more suitable for miniaturized manufacturing.

Description

technical field [0001] The invention relates to a flexible hinge, in particular to a flexible Hookee hinge, which belongs to the technical field of precision machinery and robots. Background technique [0002] With the continuous development of modern machinery in the direction of high precision, flexible hinges are favored by more and more machinery industry due to their characteristics of no mechanical friction, no gap, and high motion sensitivity, and become one of the important components in precision machinery. The flexible hinge is a new type of hinge that uses the elastic deformation of the material and its self-recovery properties to achieve movement. Compared with the traditional rigid hinge, the flexible hinge has: easy integrated design and processing, can simplify the assembly process and reduce costs; Friction and wear, thereby reducing noise and vibration, improving life; no lubrication, can avoid pollution and other advantages, so it is widely used in micro-ma...

AI Technical Summary

Problems solved by technology

[0006] (1) The structure design is complex, there are many parts, processing and installation are relatively difficult, and it is not conducive to miniaturization manufacturing;

[0007] (2) There are mechanical friction and gaps, so it is difficult to ensure high motion accuracy;

[0008] (3) During actual work, the movement of one driving part will drive the position of the other driving part to change, which will generate additional moment of inertia, resulting in poor dynamic performance of the hinge, which is not conducive to the long-term use of the structure
