Problems solved by technology
Although the control direction of a single rigid universal joint is relatively accurate, the control range is limited, and it cannot realize all-round direction positioning, and once the positioning is completed, it cannot move with the outside world, sometimes causing great loss to the equipment
The use of multiple combinations makes the equipment complex and increases the difficulty of control
Although flexible universal joints are adopted by some equipment, traditional flexible universal joints are in a passive state, that is, traditional flexible universal joints require rigid adjustment or manual adjustment to achieve accurate positioning

Embodiment Construction
[0013] The hydraulic flexible universal joint is composed of a small rigid ring (1), a flexible protective ring (2), a hydraulic device (3), a cavity or a working module (4), and a working module connecting line (5). The assembly process is as follows: first connect the small section of rigid ring (1) with the flexible protective ring (2) one by one, then insert the hydraulic device (3) symmetrically into the small section of rigid ring (1), and fix it on the small section of rigid ring (1) )superior. If the working module (4) needs to be loaded, the working module (4) is fixed on the small rigid ring (1) when connecting the small rigid ring (1) and the flexible protective ring (2).
[0014] When in use, connect the two ends of the hydraulic flexible universal joint with the corresponding parts, and under the control of the expansion and contraction of the symmetrically distributed hydraulic device (3), the universal joint is bent, so that the parts at both ends move with the ...

The invention relates to a novel hydraulic flexible universal joint which is characterized by consisting of a small section of a rigid ring (1), a flexible protective ring (2), a hydraulic device (3), a hollow cavity or an operation module (4) and an operation module connecting line (5). The universal joint is easy to realize automatic control, and the short-distance rigid structure and long-distance flexible structure of the universal joint cause the universal joint to realize accurate adjustment and location, and move with the external subtle changes accordingly. The hydraulic flexible universal joint can effectively reduce the device wear, and prolong the service life of the device while ensuring the functional realization of the device, and has strong practical value.
Description
technical field [0001] The invention relates to a new type of universal joint (hydraulic flexible universal joint. It belongs to the field of mechanical design, manufacture and automation. Background technique [0002] In the field of mechanical design and manufacturing and automation, universal joints are an indispensable structure. At present, rigid universal joints are widely used in various machines, instruments and smart devices to control the direction. Although the control direction of a single rigid universal joint is relatively accurate, the control range is limited, and it cannot realize all-round direction positioning, and once the positioning is completed, it cannot move with the outside world, sometimes causing great loss to the equipment. The use of multiple combinations makes the device complex and increases the difficulty of control. Although flexible universal joints are adopted by some equipment, traditional flexible universal joints are in a passive stat...
