specific Embodiment approach 1

[0012] Specific implementation mode one: combine figure 1 and figure 2 Describe this embodiment. The Hooke hinge in this embodiment consists of a bracket 5, a bracket 2 6, a core 7 and four flexible rotary joints 8. Each flexible rotary joint 8 includes a first shell 1 and a second shell 2. , the first flexible board 3 and the second flexible board 4, the first flexible board 3 is I-shaped, the second flexible board 4 is a square board and the square board has a square through hole 4-1, the first housing 1 and the second The two shells 2 have the same structure. The first shell is made of a 210° arc plate and a 90° arc plate. The thickness of the arc plate is less than the thickness of the 210 ° arc plate, the 210 ° arc plate of the first shell is located outside the 90 ° arc plate of the second shell and the 90 ° arc plate of the first shell is set A gap is formed inside the 210° arc plate of the second housing and between the first housing and the second housing. The inne...

Abstract

The invention provides a hook joint formed by cross reed flexible joints, relates to the technical field of compliant mechanisms and solves the problems that at present, the biggest stroke of a compliant mechanism ranges from + / - 5 degrees to + / - 10 degrees, and the compliant mechanism can not fit with occasions with large turning angles. According to the technical scheme, four installation locating holes are formed in a core body, the four installation locating holes are connected with one ends of four flexible rotation joints respectively, the four flexible rotation joints are defined as a first flexible rotation joint, a second flexible rotation joint, a third flexible rotation joint and a fourth flexible rotation joint respectively, the other end of the first flexible rotation joint and the other end of the third flexible rotation joint are connected with a first support, and meanwhile the other end of the second flexible rotation joint and the other end of the fourth flexible rotation joint are fixedly connected with a second support. The hook joint is used for large stroke precise transmission mechanisms and the field of flexible transmission.

Description

technical field [0001] The invention relates to a Hooke hinge composed of cross reed flexible joints, and relates to the technical field of compliance mechanism. Background technique [0002] Traditional mechanisms are connected by rigid components in the form of kinematic pairs. There are inevitably gaps and frictions between the components that make up the kinematic pairs, which cannot meet the performance requirements of the mechanism such as high speed, high precision, and miniaturization. The compliant mechanism uses its own elastic deformation to transmit motion and force, so there is no mechanical friction, no lubrication, smooth motion, integrated processing, easy maintenance, and high precision and high resolution. [0003] The Hooke hinge is composed of two revolving pairs, which have two degrees of freedom of relative rotation, and the axes of the two rotations are perpendicular to each other. Because the two corners of the Hooke hinge are independent and the ran...
