Abstract
The utility model relates to a hydraulic rotary joint, which comprises an oil inlet (1), a fixing sleeve (2), a sealing ring (3), a protective sleeve (4), a rotating shaft (5) and an oil outlet (6). The rotating shaft (5) is mounted in the fixing sleeve (2), the oil inlet (1) and the oil outlet (6) are respectively and symmetrically positioned on the upper side and the lower side of the fixing sleeve (2), an upper oil hole and a lower oil hole are respectively and symmetrically positioned on the upper side and the lower side of the right end of the rotating shaft (5) and respectively connected with the oil inlet (1) and the oil outlet (6), and the protective sleeve (4) is screwed at the right end of the fixing sleeve (2). The hydraulic rotary joint is used in a four-axis rotary table of a processing center, and is utilized as a joint of a hydraulic fixture and a hydraulic station so as to be capable of effectively preventing oil tubes from being twisted due to four-axis rotation.
Description
Technical field
The utility model belongs to the field, particularly relates to a kind of hydraulic rotary joint.
Background technique
Hydraulic rotary joint is the equipment that is used for the hydraulic actuator delivery hydraulic pressure medium on rotating equipment, and no matter seal original paper at present is domestic, the external y-type seal ring that adopts mostly.Its shortcoming is that processing technology is complicated and high to other component processing requirement, and under High Temperature High Pressure, wearing and tearing are very fast, and therefore leakage is serious, and working life is short, changes trouble.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of hydraulic rotary joint, twines because of four rotations to prevent oil pipe.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of hydraulic rotary joint is provided; comprise filler opening; fixed cover; seal ring; protecting jacket; running shaft and oil outlet; described running shaft is installed in the fixed cover; described filler opening and oil outlet symmetry respectively are positioned at fixed cover both sides up and down; upper oil hole and following oilhole symmetry respectively are positioned at running shaft right-hand member both sides up and down; and upper oil hole is connected with oil outlet with filler opening respectively with following oilhole, and described protecting jacket spiral is at the fixed cover right-hand member.
Described upper oil hole is connected by seal ring with filler opening, and following oilhole is connected by seal ring with oil outlet.
Beneficial effect
The utility model is used in four turntables of machining center, can prevent effectively that as the joint of hydraulic fixture and hydraulic station oil pipe from twining because of four rotations.
Description of drawings
Fig. 1 is the utility model plan view.
