The embodiment of the invention discloses a hydraulic rotary actuator, and belongs to the technical field of mechanical design and solves the problem of occupancy of relative large physical space. The actuator comprises an outer tube (3) which is a cylindrical tube fixed on the rotation axle of a folding mechanism, the lower segment of the outer tube is a common hydraulic actuation tube, the lower end of the outer tube 3 is used as an oil cavity of the hydraulic actuation tube, an oil inlet valve and an oil outlet valve are formed on the wall of the lower segment of the outer tube 3. A rotation arm 4 is mounted on a piston rod 2, and a fan-shaped opening is formed on the outer tube 3 corresponding to the rotation arm 4 and used as the activity space of the rotation arm 4. A vertical slide groove is arranged on the inner ring surface of a rotation device 7 and in slide fit with the rotation arm 4. Internal thread is carved on the side edge of the upper end cover 5 and in cooperation connection with external thread of the residual fan-shaped area on the upper end of the outer tube 3 except symmetrical fan-shaped openings, the lower end surface of the side edge of the upper end cover 5 presses down the upper end surface of the rotation device 7, and a roll ball is arranged between the two end surfaces.
Description
technical field [0001] The invention relates to the technical field of mechanical design, in particular to a hydraulic rotary actuator. Background technique [0002] At present, the folding mechanism is usually used in the actuator, and the folding mechanism is a device that can be unfolded and closed according to the demand, and has a wide range of applications in mechanical engineering. [0003] Commonly used folding mechanisms mainly include: driving device, rocker arm, and connection system to complete the opening and closing of the folding mechanism through linear driving force, but the design of this folding mechanism has the problem that there are many components and requires a large physical space It is used in the design of actuators with high requirements for light weight and miniaturization. Contents of the invention [0004] Embodiments of the present invention provide a hydraulic rotary actuator, which can solve the problem of occupying a large physical space...
