Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the B-B sectional view of the utility model；
Fig. 3 is the C-C sectional view of the utility model.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings:
As shown in Figure 1, Figure 2 and Figure 3, a kind of swing hydraulic pressure cylinder, including left end cap 1, the first cylinder body 2, sealing cover 3, second
Cylinder body 4, inner valve sleeve 5, bearing cap 6, shaft coupling 7, right end cap 8, bearing 9, spool 10, valve body 11, blade 14 and steering engine 15, left end
Lid 1 and right end cap 8 are separately positioned on the left and right sides of oscillating cylinder, and the first cylinder body 2 connects left end cap 1, and steering engine 15 is fixedly mounted on
On left end cap 1, spool 10 is installed on the right side of steering engine 15,10 outside of spool is provided on the outside of inner valve sleeve 5 from inner valve sleeve 5 is provided with
Valve body 11, the second cylinder body 4 are connected to the right side of the first cylinder body 2, are equipped with bearing cap 6 on the right side of the second cylinder body 4, on 6 left side of bearing cap
Lower two sides are separately installed with a bearing 9, pass through the connection right end cap 8 of shaft coupling 7, about 11 two sides of valve body point on the right side of bearing cap 6
It is not provided with a blade 14.
About 10 two sides of spool are respectively arranged with second hydraulic fluid port 12 and first hydraulic fluid port 13.
1 top of left end cap is provided with oil inlet 16.
1 lower part of left end cap is provided with oil return opening 17.
Working principle: oil inlet is passed through high pressure oil, and oil return opening is passed through low pressure oil, and when steering engine is static, spool is also static, valve
Hydraulic fluid port on core is closed by the boss on inner valve sleeve, and height pressure oil cannot enter A chamber and B chamber, and single blade is from servo-hydraulic at this time
Oscillating cylinder is in middle position halted state;When steering engine rotates clockwise certain angle, it will drive spool and rotates clockwise together
Certain angle, P hydraulic fluid port and T hydraulic fluid port on spool are opened, at this point, then the high pressure oil of valve core inside passes through first through P hydraulic fluid port
Hydraulic fluid port enters A chamber, and from B chamber, through the second hydraulic fluid port, then pass through T hydraulic fluid port enters back oil road to the low pressure oil of valve core inside.Because of A chamber and B chamber
Internal pressure is different, under the effect of two cavity pressure differences, so that inner valve sleeve and valve body rotate clockwise together, when inner valve sleeve and valve body
With valve core rotation equal angular, during the entire process of the valve port on spool is closed, the rotation of valve body output shaft will drive right end
Load rotation, to complete process of the single blade from servo-hydraulic oscillating cylinder output torque, realize valve body to the position of spool with
Track;When steering engine rotates counterclockwise, single blade it is hydraulic from servo oscillating cylinder interior working condition with it is clockwise when it is opposite.
