The traditional assembly method often relies on manual operation, and the assembly of the electric cylinder push rod and the cylinder barrel is completed by manual alignment, rotation and screwing. However, this method has many shortcomings.

[0003] First, the accuracy of manual assembly is limited by the skills and experience of the operator, and it is difficult to ensure that every assembly can meet the ideal accuracy requirements. This may lead to unstable performance and shortened life of the electric cylinder during use. Secondly, the efficiency of manual assembly is low, especially in the case of large-scale and large-size production, the speed and accuracy of manual operation often cannot meet production needs. This not only increases production costs, but also limits the production capacity of electric cylinders. In addition, traditional assembly methods also have safety hazards. During the assembly process, operators need to frequently contact the parts of the electric cylinder. If the operation is improper or the equipment fails, safety accidents are likely to occur.

The redundant design of the dual servo system not only improves the stability of the system, but also ensures the accuracy and consistency during the movement process through synchronous control, meeting the requirements of high-precision position adjustment for large-size electric cylinder assembly. (2) Strong driving force and stability: The dual servo drive motor provides sufficient driving force, which can easily cope with the weight and inertia of the long shaft of the large-size electric cylinder, ensuring that no slippage or jamming occurs during the adjustment process. At the same time, the dual gear rack mechanism has high transmission efficiency and good stability, further enhancing the reliability of the X-axis moving actuator. (3) Efficient transmission and response: The direct cooperation between the servo drive motor and the transmission rack reduces the intermediate links in the transmission chain and improves the transmission efficiency and response speed. This enables the electric cylinder long shaft to be adjusted in the X direction quickly and accurately during the assembly process, thereby improving the assembly efficiency. (4) Compact structure and space optimization: The two sets of rotating support mechanisms share a set of X-axis guide rail modules, which not only saves space resources, but also makes the structure of the entire device more compact and reasonable. This design is conducive to realizing complex three-dimensional position adjustment functions in a limited space, meeting the actual needs of large-size electric cylinder assembly sites. (5) Easy maintenance and upgrade: The modular design makes the various components of the X-axis moving actuator relatively independent, which is convenient for maintenance and replacement. At the same time, with the continuous advancement of technology, key components such as servo drive motors and transmission racks can be easily upgraded to maintain the performance advantages and competitiveness of the device.

[0032] As a preferred embodiment, the Y-direction moving execution component 5 includes a cylinder sliding seat 214 and an electric push rod sliding seat 314 movably mounted on a cylinder support frame and an electric push rod support frame, wherein the sliding direction of the cylinder sliding seat and the electric push rod sliding seat slides along the Y direction, and the bottom of the cylinder sliding seat 214 and the electric push rod sliding seat 314 are respectively arranged with a Y-axis guide rail 1 215 and a Y-axis guide rail 2 315 along the Y-axis direction, and the cylinder support frame and the electric push rod support frame are respectively installed with a Y-axis slider 1 216 and a Y-axis slider 2 316 that cooperate with the Y-axis guide rail 1 and the Y-axis guide rail 2, and the cylinder support frame and the electric push rod support frame are respectively installed with a cylinder sliding seat 214 and an electric push rod sliding seat 314. The push rod support frame is respectively equipped with a Y-axis electric cylinder 1 217 and a Y-axis electric cylinder 2 317 for driving the cylinder sliding seat and the electric push rod sliding seat to slide along the Y-axis direction; the Z-axis moving execution component includes a Z-axis electric cylinder 1 218 and a Z-axis electric cylinder 2 318 respectively installed downward on the cylinder sliding seat and the electric push rod sliding seat, the driving end of the Z-axis electric cylinder 1 218 is connected to the cylinder clamping station 13, and the Z-axis electric cylinder 1 drives the cylinder clamping station to adjust in the Z-axis direction, and the driving end of the Z-axis electric cylinder 2 is connected to the electric push rod clamping station 14, and the Z-axis electric cylinder 2 drives the electric push rod clamping station 14 to adjust in the Z-axis direction.

[0033] The design advantages of the above scheme are as follows: (1) Multi-dimensional precise adjustment: The addition of Y-axis and Z-axis moving actuators enables the entire device to achieve comprehensive and precise adjustment of the long axis of the electric cylinder in three-dimensional space. The Y-axis moving actuator achieves precise movement along the Y-axis direction through the cooperation of the sliding seat, the Y-axis guide rail and the Y-axis electric cylinder; while the Z-axis moving actuator directly drives the rotation clamping station to adjust in the Z-axis direction through the Z-axis electric cylinder. This multi-dimensional adjustment capability greatly improves the flexibility and precision of the assembly process. (2) Efficient and automated operation: Both the Y-axis and Z-axis moving actuators use electric cylinders as the driving source to achieve automated operation. The electric cylinder has the characteristics of fast response speed and high control accuracy, and can quickly and accurately complete the position adjustment task, thereby improving assembly efficiency. At the same time, the automated control of the electric cylinder also reduces the need for manual intervention, reduces human errors, and improves the consistency of assembly quality. (3) Compact structure and stability: The Y-axis moving actuator achieves stable sliding along the Y-axis direction through the ingenious combination of the sliding seat and the support frame; while the Z-axis moving actuator is directly installed on the sliding seat, with a compact and stable structure. This design not only saves space resources, but also ensures the stability and reliability of the entire device during the adjustment process. (4) Easy maintenance and upgrade: The modular design of the Y-axis and Z-axis moving actuators makes each component relatively independent, which is convenient for maintenance and replacement. When a component fails or needs to be upgraded, it can be handled separately without affecting the normal operation of the entire device. This design reduces maintenance costs and time costs and improves the availability and economy of the device. (5) Enhanced assembly flexibility: Through the synergistic effect of the Y-axis and Z-axis moving actuators, the long axis of the electric cylinder can be flexibly adjusted in different directions. This flexibility not only helps to solve complex problems in the assembly process, but also can adapt to the assembly requirements of long axis of electric cylinders of different sizes and shapes. This is of great significance for improving assembly efficiency and reducing assembly difficulty. In summary, the optimal design of the Y-axis and Z-axis moving actuators has shown significant beneficial effects in improving assembly accuracy, achieving efficient automated operation, ensuring compactness and stability of the structure, reducing maintenance costs, and enhancing assembly flexibility.
