The hydraulic 360-degree rotary joint can realize 360-degree rotation in any direction for oil distribution or other liquid work. The structure is a base, a mandrel is fixed on the base, at least one rotary joint body, and a plurality of seals arranged between the surface of the mandrel and the rotary joint body. A plurality of oil distribution rings are arranged on the outer cylindrical surface of the mandrel, and an oil distribution pipe connected with an oil inlet is arranged in the oil distribution ring. The torque of a hydraulic 360-degree swivel joint may be very small, if you rotate it by hand, you will not feel much resistance.
The hydraulic 360-degree rotary joint has the characteristics of long service life, stable operating performance, and diverse transmission media, including compressed air, hydrogen, nitrogen, chemical mixed gas, steam, cooling water, hot water, hot oil, petroleum, sulfuric acid, beverages, etc. At the same time, hydraulic rotary joints are inexpensive.
What is the principle of hydraulic rotary joint?
1. When used alone, it introduces pressure oil from the shell of the hydraulic power chuck (fixed) into the rotating cylinder, so that the piston moves to the right under the action of the pressure oil, overcomes the spring force and resistance, and drives the wedge to drive the jaws to loosen Artifact. When returning, the pressure oil can be relieved, and the sliding shaft can be driven by the spring return action to drive the claw to clamp the workpiece radially.
2. When used in combination, combine two rotary joints. When the left cavity of the rotating cylinder is filled with oil and the right cavity is filled with oil, the piston rod moves to the right, driving the wedge, and driving the jaw to loosen the workpiece. When the right cavity of the rotating cylinder is filled with oil and the left cavity is filled with oil, the piston rod moves to the left, driving the sliding shaft, and driving the claw to clamp the workpiece radially.
