[0023] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0024] Example 1: As Figure 1-6 A three-dimensional position adjustment support device for a long shaft component of an electric cylinder includes a frame 1. Two sets of support mechanisms 2 for supporting the long shaft component of the electric cylinder are movably mounted side by side on the frame, and the distance between the two sets of support mechanisms 2 is adjustable. A support frame 7 is movably mounted on the support mechanism. A clamping support station 3 for clamping the long shaft component of the electric cylinder is mounted on the support frame. A moving actuator for adjusting the clamping support station along the X, Z, and Y directions is mounted on the support frame. The moving actuator includes an X-direction moving actuator component 4, a Y-direction moving actuator component 5, and a Z-direction moving actuator component 6. The clamping support stations of the two sets of support mechanisms cooperate to drive the long shaft component of the electric cylinder to adjust its position in three-dimensional space.

[0025] The X-axis movement execution component 4 includes an X-axis guide rail module mounted on the frame along the X-axis direction. Two sets of support mechanisms share one X-axis guide rail module. An X-axis slider that mates with the X-axis guide rail module is mounted at the bottom of the support frame. An X-axis drive mechanism for driving the support frame to move along the X-axis guide rail module is mounted on the support frame. The X-axis drive mechanism is a dual servo drive motor driven dual gear rack mechanism. The X-axis drive mechanism includes a transmission rack 11 mounted on the frame corresponding to the two sides of the support frame. The transmission rack is arranged along the X-axis direction. Servo drive motors 12 are mounted on the support frame corresponding to the positions of the transmission racks. The drive ends of the servo drive motors are connected to drive gears 13 that mate with the transmission racks. The X-axis guide rail module includes X-axis guide rail one 8 and X-axis guide rail two 9 mounted on the frame corresponding to the two sides of the support frame. Two sets of X-axis sliders 10 are matched and installed.

[0026] The advantages of the above structure design: The preferred design of the X-axis movement actuator has the following benefits: (1) High-precision positioning: The dual servo drive motor drives the dual gear rack mechanism, realizing high-precision movement control of the support frame along the X-axis. 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 high-precision position adjustment requirements of the 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 there will be no slippage or jamming 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 movement actuator. (3) High-efficiency 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 quickly and accurately adjusted in the X-axis during the assembly process, improving the assembly efficiency. (4) Compact structure and optimized space: The two sets of support mechanisms share a single X-axis guide rail module, which not only saves space resources but also makes 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 to maintain and upgrade: The modular design makes each component of the X-axis movement 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.

[0027] In a preferred embodiment, the Y-axis movement actuator 5 includes a sliding seat 14 movably mounted on a support frame. The sliding seat slides along the Y-axis. A Y-axis guide rail 15 is arranged at the bottom of the sliding seat along the Y-axis. A Y-axis slider 16 that cooperates with the Y-axis guide rail is mounted on the support frame. A Y-axis electric cylinder 17 for driving the sliding seat to slide along the Y-axis is mounted on the support frame. The Z-axis movement actuator 6 includes a Z-axis electric cylinder 18 mounted downward on the sliding seat. The drive end of the Z-axis electric cylinder is connected to a clamping support station. The Z-axis electric cylinder drives the clamping support station to adjust in the Z-axis direction.

[0028] The design advantages of the above scheme are: (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 shaft 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 clamping support 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 in the assembly process. (2) Efficient automated operation: Both the Y-axis and Z-axis moving actuators use electric cylinders as the driving source to achieve automated operation. Electric cylinders have the characteristics of fast response speed and high control precision, which can quickly and accurately complete the position adjustment task and improve assembly efficiency. At the same time, the automated control of electric cylinders also reduces the need for manual intervention, reduces human error, 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 to maintain 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, flexible adjustment of the electric cylinder long shaft component in different directions can be achieved. This flexibility not only helps to solve complex problems in the assembly process, but also adapts to the assembly requirements of electric cylinder long shaft components of different sizes and shapes. This is of great significance for improving assembly efficiency and reducing assembly difficulty. In summary, the preferred design of the Y-axis and Z-axis moving actuators shows significant beneficial effects in improving assembly accuracy, achieving efficient automated operation, ensuring structural compactness and stability, reducing maintenance costs, and enhancing assembly flexibility.

[0029] In a preferred embodiment, the clamping support station includes a lower support plate 19 and an upper clamping plate 20 mounted on a support frame. The support surface of the lower support plate is V-shaped, and the upper clamping plate is mounted on the support frame at a position directly above the lower support plate. A clamping distance adjustment mechanism 21 for changing the distance between the lower support plate and the upper clamping plate is mounted on the support frame. A clamping pressure sensor is mounted on the pressing surface of the upper clamping plate. The clamping distance adjustment mechanism includes a pressing frame mounted on the support frame. The lower support plate and the upper clamping plate are both movably mounted in the pressing frame. A guide rod 24 is mounted in the pressing frame along the lifting direction of the upper clamping plate. Guide sleeves 25 that cooperate with the guide rods are mounted on both the lower support plate and the upper clamping plate. A clamping drive mechanism for driving the lower support plate and the upper clamping plate to reciprocate up and down along the guide rods is mounted on the pressing frame.

[0030] The design advantages of the above structure are as follows: (1) Stable and reliable clamping effect: The lower support plate adopts a V-shaped support surface design, which can better adapt to the shape of the electric cylinder long shaft and provide stable support. At the same time, the upper clamping plate cooperates with the lower support plate, and the clamping distance adjustment mechanism precisely controls the distance between the two to achieve effective clamping of the electric cylinder long shaft. This design ensures the stability and reliability of the clamping process and avoids assembly errors or damage caused by unstable clamping. (2) High-precision clamping distance adjustment: The clamping distance adjustment mechanism achieves high-precision adjustment of the distance between the lower support plate and the upper clamping plate through the synergistic action of the clamping frame, guide rod, guide sleeve and clamping drive mechanism. This adjustment capability allows the device to flexibly adapt to electric cylinder long shafts of different sizes and shapes, improving the versatility and accuracy of assembly. (3) Intelligent clamping control: The clamping pressure sensor installed on the upper clamping plate can monitor the pressure change during the clamping process in real time and provide feedback signals to the clamping drive mechanism. Through intelligent control algorithm, precise control of clamping force can be achieved to avoid assembly problems caused by excessive tightness or looseness. This intelligent control improves the automation and precision of assembly. (4) Compact structure and easy maintenance: The clamping support station and its clamping spacing adjustment mechanism adopt a modular design, which is compact and easy to disassemble and install. This design not only saves space resources, but also facilitates subsequent maintenance and upgrades. When a component needs to be replaced or repaired, it can be operated separately without affecting the normal operation of the entire device. (5) Improve assembly efficiency and safety: Through automated clamping and spacing adjustment functions, the need for manual intervention is reduced, and assembly efficiency is improved. At the same time, the stable clamping effect and precise control capability also reduce the safety risks in the assembly process and ensure the safety of operators.

[0031] In a preferred embodiment, the clamping drive mechanism includes a clamping motor 26 mounted on the clamping frame. The clamping motor is connected to a drive screw 27 via a belt drive. Threaded sleeves 28 that thread with the drive screw are installed on the lower support plate and the upper clamping plate. The clamping frame and the support frame are connected by a first rotating shaft 31 arranged in the Y-axis direction and a second rotating shaft 32 arranged in the Z-axis direction, forming a cross-shaft structure. The clamping frame is also equipped with a Y-axis limiting shaft 33 and a Z-axis limiting shaft 32. The limiting shaft 34 is parallel to the first rotation shaft in the Y-axis direction and parallel to the second rotation shaft in the Z-axis direction. The support frame is equipped with matching arc-shaped limiting groove 29 and arc-shaped limiting groove 30 at the positions corresponding to the limiting shafts in the Y-axis and Z-axis directions, respectively. The clamping frame includes an outer frame 22 and an inner frame 23. The inner frame is rotatably installed inside the outer frame. The first rotation shaft and the limiting shaft in the Y-axis direction are installed between the outer frame and the inner frame, and the second rotation shaft and the limiting shaft in the Z-axis direction are installed between the outer frame and the support frame.

[0032] The above structural design has the following advantages: (1) High-efficiency and precise clamping drive: The clamping drive mechanism adopts a design in which the clamping motor is connected to the drive screw through belt transmission, realizing precise driving of the lower support plate and the upper clamping plate. This design not only has high transmission efficiency, but also ensures the uniform application of clamping force, avoiding assembly problems caused by uneven clamping force. At the same time, the threaded cooperation between the threaded sleeve and the drive screw further improves the clamping accuracy and stability. (2) Flexible adjustment of the clamping frame: The clamping frame and the support frame form a cross shaft structure through the rotation shaft one arranged in the Y-axis direction and the rotation shaft two arranged in the Z-axis direction, which allows the clamping frame to be flexibly rotated and adjusted in both directions. This design not only improves the adaptability of the device, but also meets the assembly requirements of different angles and directions. At the same time, the cooperation between the Y-axis direction limiting shaft and the Z-axis direction limiting shaft and the arc-shaped limiting groove one and arc-shaped limiting groove two on the support frame ensures the stability and accuracy of the clamping frame during the adjustment process. (3) Compact and stable structure: The clamping frame adopts a nested design of outer and inner frames, with the inner frame rotating and installed inside the outer frame, making the entire structure more compact and stable. This design not only saves space resources but also improves the rigidity and durability of the device. At the same time, the installation position of the rotation axis and the Y-axis limiting axis (although the Y-axis limiting axis is not directly mentioned in the original text, it is inferred from the context that it may refer to the structure related to the stability of the clamping frame in the X-axis direction) also ensures the stability and reliability of the clamping frame in multiple directions. (4) Improved assembly efficiency and flexibility: Through the optimized design of the clamping drive mechanism and the clamping frame, the entire device can complete the clamping and position adjustment tasks more efficiently and flexibly during the assembly process. This not only improves the assembly efficiency but also reduces the difficulty of operation and labor costs. At the same time, the flexible adjustment capability of the clamping frame also enables the device to adapt to the assembly needs of more types of electric cylinder long shaft parts. (5) Enhanced user experience and ease of maintenance: The optimized design makes the entire device smoother and more stable during operation, improving the user experience. At the same time, the modular design also facilitates subsequent maintenance and upgrade work. When a component needs to be replaced or repaired, it can be operated independently without affecting the normal operation of other components.
