[CN 201710726283.1] A Lightweight and Flexible Rotating Structure of Hydraulic Manipulator


[CN 201710726283.1] A Lightweight and Flexible Rotating Structure of Hydraulic Manipulator Title: A Lightweight and Flexible Rotating Structure of Hydraulic Manipulator Application Number: CN 201710726283.1 Applicant: Chongqing Lanlue Road New Technology Co., Ltd. Application Date: 2017-8-22 Patent Type: Invention Application The present invention discloses a Lightweight and Flexible Rotating Structure of Hydraulic Manipulator, including two flow channel collecting plates, and a joint body is arranged between the two flow channel collecting plates, the joint body comprises a fixing piece, a rotating piece and a joint shell which are sleeved from inside to outside in sequence, two flow channel collecting plates are respectively connected with the fixing piece and the rotating piece, at least one oil passage runs through the two flow channel collecting plates and the joint body, and the oil passage flows in from one flow channel collecting plate and flows out from the other flow channel collecting plate after flowing through the joint body, the beneficial effect of adopting the present invention is that the hydraulic oil flow channels are all arranged inside the rotary joint. Compared with the traditional rotary joint, the external oil pipe is omitted, the weight of the rotary joint of the manipulator is effectively reduced, and its flexibility is improved., And there will be no interference with the tubing like a traditional manipulator when rotating.
