Description

Technical Field

[0001] This utility model relates to the field of servo hydraulic cylinder technology, and in particular to a servo hydraulic cylinder with optimized structure. Background Technology

[0002] A servo hydraulic cylinder is a high-precision actuator that combines hydraulic and servo control technologies, enabling precise position, speed, and force control. Its core principle is to use the pressure of hydraulic oil to push a piston, converting hydraulic energy into mechanical energy to drive the load. Servo hydraulic cylinders are characterized by high precision, high speed, high reliability, and high efficiency, and are widely used in industrial automation, robotics, metallurgical equipment, machine tools, and construction machinery.

[0003] Traditional servo hydraulic cylinders are typically installed in a fixed manner, which limits their angle adjustment capabilities and makes it difficult to adapt to complex and ever-changing working environments and installation requirements. For example, in some confined spaces or installation scenarios with special angles, the installation and adjustment process of fixed hydraulic cylinders is often cumbersome and may not even meet the actual needs. Therefore, we propose a servo hydraulic cylinder with optimized structure. Utility Model Content

It can not only extend the service life of the servo hydraulic cylinder body, but also reduce the performance degradation and maintenance costs caused by wear.

[0012] As a preferred embodiment of this utility model, multiple connecting blocks are fixedly connected to the bottom of the servo hydraulic cylinder body near both the front and back sides.

[0013] As a preferred embodiment of this utility model, the plurality of connecting blocks are bolted to the fixing base.

[0015] As a preferred embodiment of this utility model, one bottom end of the connecting shaft is connected to the driven gear, one top end of the connecting shaft is connected to the fixed base, and the output end of the drive motor is connected to the driving gear.

Through the design of the adjustment component, the drive gear can be driven to rotate under the drive of the drive motor, and then the driven gear and the connecting shaft can be driven to rotate through gear meshing transmission, so as to realize the angle adjustment of the servo hydraulic cylinder body on the mounting base; this increases the flexibility of the servo hydraulic cylinder in the installation process, enabling it to adapt to more different working environments and installation requirements.

[0028] Example 1

[0029] like Figure 1-4As shown, this utility model provides a technical solution: a structurally optimized servo hydraulic cylinder, including a servo hydraulic cylinder body 1, a cylinder sleeve 101 inside the servo hydraulic cylinder, a piston head 102 inside the cylinder sleeve 101, a piston rod 1021 on one side of the piston head 102, and a plurality of piston rings 1022 surrounding the piston head 102. An outlet 103 is provided on one side of the servo hydraulic cylinder body 1, and an outlet sleeve 1031 is provided inside the outlet 103. One end of the piston rod 1021 extends to the outside through the outlet 103. A plasma coating 1011 is provided around the inner wall of the cylinder sleeve 101. The servo hydraulic cylinder body 1 is the basic structure of the overall device. The internally provided cylinder sleeve 101 not only provides a movement track for the piston head 102, but also enhances the stability and durability of the hydraulic cylinder through its structure. The piston head 102 cooperates with the inner wall of the cylinder sleeve 101 to form a high-pressure liquid working chamber. Multiple piston rings 1022 surrounding the cylinder liner serve as a seal to prevent high-pressure liquid from leaking from the gap between the piston head 102 and the cylinder liner 101, ensuring the working efficiency and performance of the hydraulic cylinder. The piston rod 1021 on one side of the piston head 102 is used to transmit the linear motion or force generated by the hydraulic cylinder to external equipment. The piston rod 1021 extends to the outside through the outlet 103 and connects to the component that needs to be driven. The outlet sleeve 1031 surrounding the outlet 103 further enhances the stability and sealing of the extended part of the piston rod 1021, preventing liquid leakage. The plasma coating 1011 surrounding the inner wall of the cylinder liner 101 has the characteristics of high hardness, high wear resistance and high corrosion resistance, which can significantly improve the durability and wear resistance of the inner wall of the cylinder liner 101. It can not only extend the service life of the servo hydraulic cylinder body 1, but also reduce the performance degradation and maintenance costs caused by wear.

[0030] Example 2

[0031] like Figure 1-4As shown, a servo hydraulic cylinder with optimized structure is disclosed. The servo hydraulic cylinder body 1 has a fixed base 2 at its bottom. Multiple connecting blocks 104 are fixedly connected to the bottom of the servo hydraulic cylinder body 1 near both the front and back sides. The multiple connecting blocks 104 are bolted to the fixed base 2. An adjustment assembly 3 is provided at the bottom of the fixed base 2. The adjustment assembly 3 includes a mounting base 301. A connecting shaft 302 is provided at the top of the mounting base 301. A driven gear 303 is provided inside the mounting base 301, meshing with a driving gear 304. A drive motor 305 is provided on the other side of the mounting base 301. One end of the bottom of the connecting shaft 302 is connected to the driven gear 303. One end of the servo hydraulic cylinder is connected to the fixed base 2, and the output end of the drive motor 305 is connected to the drive gear 304. Through the adjustment component 3, including the mounting base 301, the connecting shaft 302, the driven gear 303, the drive gear 304 and the drive motor 305, the servo hydraulic cylinder body 1 can be driven by the drive motor 305 to rotate the drive gear 304 during installation. In turn, the driven gear 303 and the connecting shaft 302 are rotated through gear meshing transmission, thereby realizing the angle adjustment of the servo hydraulic cylinder body 1 on the mounting base 301. This increases the flexibility of the servo hydraulic cylinder during installation, enabling it to adapt to more different working environments and installation requirements.

[0032] The working process of this utility model is as follows: When using a structurally optimized servo hydraulic cylinder, the servo hydraulic cylinder body 1 is the basic structure of the entire device. The cylinder liner 101 inside it not only provides a motion track for the piston head 102, but also enhances the stability and durability of the hydraulic cylinder. The piston head 102 is set inside the cylinder liner 101, and a piston rod 1021 is set on one side of the piston head 102 to transmit the linear motion or force generated by the hydraulic cylinder to external equipment. Multiple piston rings 1022 are sleeved around the piston head 102, which play a crucial sealing role, preventing high-pressure liquid from leaking from the gap between the piston head 102 and the cylinder liner 101, ensuring the working efficiency and performance of the hydraulic cylinder; the plasma coating 1011 surrounding the inner wall of the cylinder liner 101 has high hardness and high... The wear resistance and high corrosion resistance significantly improve the durability and wear resistance of the inner wall of the cylinder liner 101. The bottom of the servo hydraulic cylinder body 1 is provided with a fixed seat 2, and the bottom of the fixed seat 2 is equipped with an adjustment component 3. The adjustment component 3 includes a mounting base 301, a connecting shaft 302, a driven gear 303, a driving gear 304, and a drive motor 305. Driven by the drive motor 305, the driving gear 304 can be rotated, which in turn drives the driven gear 303 and the connecting shaft 302 to rotate through gear meshing transmission, thereby realizing the angle adjustment of the servo hydraulic cylinder body 1 on the mounting base 301. The design of the adjustment component 3 increases the flexibility of the servo hydraulic cylinder body 1 during installation, enabling it to adapt to more different working environments and installation requirements.
