[0002] A hydraulic cylinder, also known as a hydraulic cylinder, is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has a simple structure and reliable operation. When used to achieve reciprocating motion, it eliminates the need for a speed reduction device and has no transmission backlash, resulting in smooth movement. Therefore, it is widely used in the hydraulic systems of various machines. The output force of a hydraulic cylinder is directly proportional to the effective area of ​​the piston and the pressure difference between its two sides. A hydraulic cylinder is basically composed of a cylinder barrel and cylinder head, a piston and piston rod, a sealing device, a buffer device, and an exhaust device.

[0020] Please see Figure 1-4A steerable shifting hydraulic cylinder includes a piston rod 1, a pressure plate 10 on the outer side of the piston rod 1, a rotating plate 12 fixedly mounted on the outer surface of the pressure plate 10, two connecting rods 11 threadedly connected to the inner wall of the rotating plate 12, the outer surface of each connecting rod 11 being threadedly connected to the inner wall of the pressure plate 10, a fixed base plate 14 below the rotating plate 12, a rotating groove 13 formed on the upper surface of the fixed base plate 14, the outer surface of the rotating plate 12 contacting the inner sidewall of the rotating groove 13, a drive motor 5 fixedly mounted on the upper surface of the fixed base plate 14, a support shaft 18 fixedly mounted on the output end of the drive motor 5, and the outer surface of the support shaft 18 being fixedly connected to the inner wall of the rotating plate 12.

[0021] Two sets of fixing bolts 15 are installed at the bottom of the drive motor 5. The outer surface of each fixing bolt 15 is threaded to the inner wall of the fixing base plate 14. The fixing bolts 15 serve to connect the drive motor 5 and the fixing base plate 14, which is convenient for the installation and disassembly of the drive motor 5. Two bearings 17 are fixedly embedded inside the fixing base plate 14. The inner wall of each bearing 17 is fixedly connected to the outer surface of the support shaft 18. The bearings 17 support the rotation of the support shaft 18, which helps to reduce the wear of the support shaft 18 during rotation. Nuts 16 are threaded to the outer surface of each connecting rod 11. The outer surface of each nut 16 contacts the outer surface of the rotating plate 12. The nuts 16 fasten the connecting rod 11, which helps to prevent the rotating plate 12 from loosening on the pressure plate 10.

[0022] A cylinder tube 4 is provided on the outer side of the piston rod 1. A rear cover 7 is provided on the left side of the cylinder tube 4. The left side of the rear cover 7 contacts the right side of the pressure plate 10. A front cover 3 is fixedly installed on the right side of the cylinder tube 4. The cylinder tube 4, the front cover 3, and the rear cover 7 are provided. The rear cover 7, like the front cover 3, is the two end parts of the oil cylinder. Its main function is to seal the oil cylinder to protect the internal oil and parts from external damage. A valve plate 2 is provided on the right side of the front cover 3. A sensing fixing plate 6 is fixedly installed on the outer surface of the rear cover 7. The function of the sensing fixing plate 6 is to sense the working state of the cylinder so that the control circuit can receive the signal from the sensing switch and make the next action. A buffer piston body 9 is provided inside the cylinder tube 4. The buffer piston body 9 limits the rising speed of the needle valve to achieve the ideal injection pattern. Throttling needles 8 are provided inside the front cover 3 and the rear cover 7. By providing throttling needles 8, the valve port size can be adjusted according to the fluid speed to control the fluid velocity and flow rate.

[0023] The working principle of this utility model is as follows: In use, the hydraulic cylinder uses a hydraulic system to flow hydraulic oil from one place to another, thereby pushing the piston rod 1 to achieve mechanical movement. After the hydraulic oil is pressurized, it enters the cylinder through the cylinder tube 4, pushing the piston rod 1 to move towards the unpressurized side, while simultaneously pushing the oil pressure on the unpressurized side back to the control valve. When the hydraulic oil pressure decreases or disappears, the hydraulic cylinder rebounds due to the force of a spring or weight. When fixing the cylinder tube 4 and pressure plate 10 as a whole, a fixed base plate 14 can be used for installation. First, install the fixed base plate 14 at the usage position to complete the overall installation of the hydraulic cylinder. When adjusting its direction, the drive motor 5 can be started. The drive motor 5 drives the rotating plate 12 to rotate via the support shaft 18. Since the rotating plate 12 is connected to the pressure plate 10, it can be driven by the pressure plate 10 to change its direction of movement. The rotation angle can be selected according to the usage requirements to facilitate changes in the extension angle, position, and direction of the hydraulic cylinder.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
