It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.
[0032] Example 1: Figure 1-6 A multi-point rotation support device for shaft parts, comprising a frame 1, on which two groups of rotation support mechanisms 2 for supporting long shaft parts of electric cylinders are movably installed side by side, and the distance between the two groups of rotation support mechanisms 2 can be adjusted; a support frame 7 is movably installed on the rotation support mechanism, and a rotation clamping station 3 for clamping the long shaft parts of the electric cylinder is installed on the support frame, and a mobile actuator for adjusting the rotation clamping station along the X direction, Z direction, and Y direction is installed on the support frame, and the mobile actuator includes an X-direction mobile actuator component 4, a Y-direction mobile actuator component 5, and a Z-direction mobile actuator component 6; a rotation actuator for driving the shaft parts on the rotation clamping station to rotate is also installed on one group of the rotation support mechanisms, and the cooperation of the two groups of rotation support mechanisms drives the shaft parts to adjust their positions and rotate in three-dimensional space.
[0033] The X-axis moving execution component 4 includes an X-axis guide module installed on the frame along the X-axis direction, and two sets of rotating support mechanisms share one set of X-axis guide modules; an X-axis slider that cooperates with the X-axis guide module is installed at the bottom of the support frame, and an X-axis driving mechanism for driving the support frame to move along the X-axis guide module is installed on the support frame; the X-axis driving mechanism is a dual servo drive motor driven dual gear rack mechanism, the X-axis driving mechanism includes a transmission rack 11 installed on the frame at positions on both sides of the support frame, the transmission rack is arranged along the X-axis direction, and servo drive motors 12 are respectively installed at positions corresponding to the transmission rack on the support frame, and the driving end of the servo drive motor is connected to a driving gear 13 that cooperates with the transmission rack; the X-axis guide module includes an X-axis guide rail 1 8 and an X-axis guide rail 2 9 installed on the frame at both sides of the support frame, and two sets of X-axis sliders 10 are installed in a matching manner.
[0034] Design advantages of the above structure: The beneficial effects of the preferred design of the above X-axis moving actuator are mainly reflected in the following aspects: (1) High-precision positioning: The dual servo drive motor drives the dual gear rack mechanism to achieve high-precision movement control of the support frame along the X-axis direction. 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.
[0035] As a preferred embodiment, the Y-axis moving execution component 5 includes a sliding seat 14 movably mounted on a support frame, the sliding direction of the sliding seat slides along the Y direction, a Y-axis guide rail 15 is arranged at the bottom of the sliding seat along the Y-axis direction, a Y-axis slider 16 cooperating with the Y-axis guide rail is installed on the support frame, and a Y-axis electric cylinder 17 for driving the sliding seat to slide along the Y-axis direction is installed on the support frame; the Z-axis moving execution component 6 includes a Z-axis electric cylinder 18 mounted downward on the sliding seat, the driving end of the Z-axis electric cylinder is connected to the rotating clamping station, and the Z-axis electric cylinder drives the rotating clamping station to adjust in the Z-axis direction.
[0036] 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 accuracy 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 and stable structure: 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 preferred 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.

[0038] The design advantages of the above structure are: (1) Stable and reliable clamping effect: Through the cooperation of the lower support wheel group and the upper clamping wheel group of the V-shaped support surface, it is possible to achieve stable clamping of cylindrical or similar shaped objects. This design can not only effectively prevent the object from sliding or offsetting during rotation, but also adapt to objects of different diameters, thereby improving the versatility and flexibility of the equipment. (2) Accurate clamping spacing adjustment: The clamping spacing adjustment mechanism allows the user to accurately adjust the spacing between the lower support wheel group and the upper clamping wheel group according to the size and shape of the object. This helps to ensure that the object is clamped evenly and tightly, thereby improving the accuracy and efficiency of processing or inspection. (3) Real-time monitoring and protection: The application of torque sensors and clamping pressure sensors enables users to monitor the torque and clamping force generated during rotation in real time. This helps to detect abnormal conditions such as overload and jamming in a timely manner, thereby protecting the safety of the equipment and the object being processed. (4) Compact structure and easy maintenance: The entire rotating clamping station adopts a modular design, with tight connections and compact structure between the components. This not only reduces the footprint of the equipment, but also facilitates daily maintenance and maintenance for users. At the same time, due to the clear matching relationship between the various components, the probability of failure is also reduced. (5) Improve production efficiency: Through automated control, users can easily achieve operations such as clamping, rotating and releasing objects. This not only reduces the labor intensity of workers, but also improves production efficiency and product quality. In addition, since the equipment can operate stably and reliably, it also reduces production interruptions and losses caused by equipment failure.

The limiting axis 34, the limiting axis in the Y-axis direction is parallel to the rotation axis one, and the limiting axis in the Z-axis direction is parallel to the rotation axis two. The corresponding arc limiting grooves 1 29 and arc limiting grooves 2 30 are installed on the support frame at the positions corresponding to the limiting axis in the Y-axis direction and the limiting axis in the Z-axis direction; wherein the clamping frame includes an outer frame 22 and an inner frame 23, the inner frame is rotatably installed in the outer frame, the rotation axis one and the limiting axis in the X-axis direction are both installed between the outer frame and the inner frame, and the rotation axis two and the limiting axis in the Y-axis direction are both installed between the outer frame and the support frame.
[0040] The above structural design has the following advantages: (1) Efficient and accurate clamping drive: The clamping drive mechanism adopts a design in which the clamping motor is connected to the drive screw through a belt drive, thereby realizing the precise drive of the lower support wheel group and the upper clamping wheel group. This design not only has high transmission efficiency, but also ensures the uniform application of the clamping force, thereby avoiding assembly problems caused by uneven clamping force. At the same time, the threaded sleeve and the threaded cooperation of the drive screw further improve the clamping accuracy and stability. (2) Flexible clamping frame adjustment: The clamping frame and the support frame form a cross-axis structure through the rotating axis 1 arranged in the Y-axis direction and the rotating axis 2 arranged in the Z-axis direction, so that the clamping frame can be flexibly rotated and adjusted in two 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 limit axis and the Z-axis direction limit axis and the arc limit groove 1 and arc limit groove 2 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 an outer frame and an inner frame, and the inner frame is rotatably installed in 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 rotating axis and the X-axis limit axis (although the X-axis limit axis is not directly mentioned in the original text, it is speculated based on 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.
