Detailed Description
The present invention will be further described with reference to the following examples.
As shown in figures 1-6, an embodiment of the present invention, a swing hydraulic cylinder with a built-in two-way overflow valve, comprises a cylinder assembly 4, a left support plate 1 and an end cover 7 are respectively fixed on the left and right sides of the cylinder assembly 4, the left support plate 1 and the end cover 7 are connected with the inner cavity of the cylinder assembly 4 in a sealing manner, a locking nut 9 is fixedly arranged in the inner hole on the right side of the end cover 7 in a sealing manner, a right support plate 8 is fixedly arranged on the right side of the end cover 7, two side plates 2 are fixedly arranged on the lower side of the outer part of the cylinder assembly 4 perpendicularly to the left support plate 1, the large planes of the two side plates 2 are parallel to each other and parallel to the axis of the cylinder assembly 4, an inner gear ring 5 is fixedly arranged on the inner wall of the cylinder assembly 4, inner gear ring teeth are arranged on the inner wall of the inner gear, the middle sleeve oblique outer tooth 601 is meshed and connected with an inner gear ring oblique inner tooth arranged on the inner wall of an inner gear ring 5, an inner shaft 3 is arranged inside a middle sleeve 6, the middle sleeve oblique inner tooth 602 is arranged on the inner wall of the middle sleeve 6, inner shaft oblique outer teeth 305 are arranged on the outer circumference of the inner shaft 3, the inner shaft oblique outer teeth 305 are meshed and connected with the middle sleeve oblique inner teeth 602, a left oil cavity 13 and a right oil cavity 14 are respectively arranged on two sides of the middle sleeve 6, a left oil hole 401 and a right oil hole 402 are arranged on the outer circle of a cylinder component 4, the left oil hole 401 and the right oil hole 402 are respectively communicated with the left oil cavity 13 and the right oil cavity 14, as seen in figure 4, an inner shaft large valve hole 303 is arranged inside the inner shaft 3, an inner shaft small valve hole 304 is communicated with the inner shaft large valve hole 303, a left overflow hole 301 and a right overflow hole 302 are respectively arranged on the front side and the back side of the inner shaft small valve hole, the internal overflow valve core 12 is arranged in the internal shaft large valve hole 301, when the internal hydraulic pressure is large, the internal pressure can be released through the internal overflow valve core 12, the buffering effect is achieved, the impact load can be reduced, the back pressure is provided, and the safety can be guaranteed.
