Abstract

The invention belongs to the field of aviation and machinery, and relates to an actuator cylinder device with a rotatable joint. According to the actuator cylinder device, an actuator cylinder is divided into a hydraulic oil supply cavity and a hydraulic oil return cavity through an outer cylinder with an oil through hole, a rotary joint with a sealing groove, a piston rod, a front end cover, a rear end cover, a locking screw, a check ring, a sealing piece and the like. A traditional connector is replaced by the rotatable connector, and the actuator cylinder can be applied to some positions rotating around the axis of the actuator cylinder at a low speed. By rotating the orientation of the actuator cylinder connector, the installation stress of a hydraulic pipeline connected with the actuator cylinder connector can be effectively reduced.

Description

technical field [0001] The invention belongs to the fields of aviation and machinery, and relates to an actuator device with a rotatable joint. Background technique [0002] Actuators commonly used in the aviation field are generally driven by a hydraulic source. When an actuator needs to be used on some structures with low-speed rotation, the actuator mounting seat needs to be set on a fixed structure, and the rotation track of the rotating structure should be considered. , so it is difficult to choose the installation position of the actuator. In addition, due to the processing tolerance of the pipeline connecting the actuator joint, there will be installation stress when installing the pipeline. Therefore, there is a need for a position-adjustable actuator. Contents of the invention [0003] In order to solve the above problems, the present invention provides an actuator with rotatable joints, which can meet the requirements of using an actuator on a low-speed rotatin...
