[CN 201721054746.6] Joint Rotating Assembly of Hydraulic Manipulator
[CN 201721054746.6] Title of Joint Rotation Assembly of Hydraulic Manipulator: Application Number of Joint Rotation Assembly of Hydraulic Manipulator: CN 201721054746.6 Applicant: Chongqing Lanlue Road New Technology Co., Ltd. Application Date: 2017-8-22 Patent Type: Utility Model The utility model discloses a joint rotation assembly of hydraulic manipulator, including a joint shaft and a joint shaft sleeve, the joint shaft is penetrated into the joint shaft sleeve, and at least one liquid inflow channel is provided inside the joint shaft, the joint shaft sleeve is provided with at least one liquid outflow channel corresponding to the liquid inflow channel, and the liquid outflow channel communicates with the corresponding liquid inflow channel. The beneficial effect of the utility model is that the hydraulic oil flows into the joint shaft sleeve from the inside of the joint shaft and passes through the joint The shaft sleeve flows into the next component. The oil passages are all arranged inside the rotating joint. Compared with the traditional rotating joint, the external oil pipe is omitted, it effectively reduces the weight of the rotating joint of the manipulator, improves its flexibility, and does not interfere with the tubing like the traditional manipulator.
