[0034] When the advanced slide rail type pairing device needs to be used to carry out work, first of all, with the help of lifting equipment, the propeller shaft 5 is hoisted to the top of the placing seat 17, and then slowly and smoothly put down. The placing seat 17 is based on the unique shape and size of the propeller shaft 5, and the recess or support structure inside it not only fits closely, but also has good buffering performance, so that the propeller shaft 5 can be stably placed in it without shaking or displacement. Then, the operator comes to the device and presses the start button. The motor 9 responds quickly and runs at high speed, and the rotating column 10 fixedly connected to the output end rotates quickly and stably, driving the gear 11 on the side wall to rotate. Due to the precise meshing relationship between the gear 11 and the rack 12, it slides smoothly and accurately inside the fixed seat 3. The sliding of the rack 12 drives the sliding plate 30 connected thereto to quickly and stably expand and move outward along the predetermined track. The movement of the sliding plate 30 drives the rotating plate 16. The rotating plate 16 rotates around the fixed sleeve 14 fixedly connected to the side wall of the mounting seat 13, and the other end of the rotating plate 16 drives the clamping block 15 to slide quickly toward the center of the propeller shaft 5. With the opposite movement of the clamping block 15, the propeller shaft 5 on both sides is stably clamped, achieving the fixing effect. When the propeller shaft 5 is firmly fixed, the next step is to make it move towards the coupling 8 and start the pairing process. At this time, the pulley 4 at the bottom of the fixed seat 3 slides on the surface of the slide bar 2. The sliding of the pulley 4 drives the entire fixed seat 3 and the propeller shaft 5 carried thereon to move smoothly and accurately towards the coupling 8. The distance between them gradually decreases, and finally they are accurately connected, creating excellent conditions for the next fine and rigorous pairing process, ensuring that the entire production process proceeds smoothly and efficiently.

[0035] Reference Figures 3-4The lifting assembly plays a crucial role in the slide rail type matching device, can finely control the position of the relevant components in the vertical direction, and further optimize the whole matching operation process. The fixed block one 18 is fixedly connected to the upper surface of the bottom plate 6, providing a stable and reliable starting connection point for many rotating parts connected subsequently. The fixed block two 19 fixedly connected to the upper surface of the bottom plate 6 cooperates with the fixed block one 18. The fixed block two 19 provides a precise rotating fulcrum for the rotating bar one 20, so that the rotating bar one 20 can rotate smoothly and stably around the point. The rotating bar two 21 rotatingly connected inside the fixed block one 18 plays a key role in the power transmission link of the lifting assembly. When subjected to external driving force, the rotating bar two 21 can flexibly rotate around the connecting point inside the fixed block one 18, and its rotating action can be accurately transmitted to the connecting rod one 25 connected thereto, thereby driving the relevant components to realize the displacement in the vertical direction. The rotating bar one 20 rotatingly connected inside the fixed block two 19 closely cooperates with the rotating bar two 21. The rotating bar three 23 is rotatingly connected to one end of the connecting rod 22, playing a bridge role of connecting different rotating parts. It can smoothly transfer the rotating energy of the rotating bar one 20 to the rotating bar three 23, ensuring that the transmission direction and size of the force meet the movement logic of the lifting assembly. The connecting rod one 25 is rotatingly connected to one end of the rotating bar three 23 away from the mounting base one 7, and can drive the connecting rod one 25 to move in the vertical direction, thereby affecting the height position of the mounting base one 7. The rotating bar two 21 is rotatingly connected to the side wall of the connecting rod one 25 at one end, further strengthening the driving capacity of the connecting rod one 25. The connecting rod two 28 is rotatingly connected to one end of the rotating bar one 20 away from the fixed block two 19, and the rotating plate two 24 is rotatingly connected to the side wall of the connecting rod two 28. The rotating plate two 24 is rotatingly connected to the bottom of the mounting base one 7 at one end, and the two form a flexible support and drive structure. The rotating handle 27 is rotatingly connected to the side wall of the connecting rod one 25, and the screw rod 26 is fixedly connected to one end of the rotating handle 27, providing a convenient manual control interface for the operator. The fixed block three 29 is rotatingly connected to the side wall of the connecting rod two 28, and its own fixed connection to the upper surface of the bottom plate 6 ensures the relative stability of the whole lifting assembly structure, avoiding the movement out of control due to loosening of the fixed block three 29 during lifting operation.

[0036] When the propeller shaft 5 is close to the coupling 8, the height of the coupling 8 needs to be adjusted, at this time, the operator holds the rotating handle 27 steadily and starts to rotate counterclockwise. With the rotation of the rotating handle 27, the screw rod 26 rigidly connected thereto responds and starts to rotate synchronously. Due to the rotation of the screw rod 26, under the interaction of the threads, an axial displacement relative to the fixed block three 29 is generated. The distance between the connecting rod one 25 and the connecting rod two 28 is gradually shortened, and with the shortening of the distance, the rotating bar one 20 connected to one end of the connecting rod one 25 is pulled to start to rotate with the inner part of the fixed block two 19 as the axis, at the same time, the rotating bar two 21 connected to the other end of the connecting rod one 25 also rotates with the inner part of the fixed block one 18 as the fulcrum, cooperates with the rhythm of the rotating bar one 20, and rotates synchronously, the rotating trajectories of the two are accurate and accurate, and the rotating bar one 20 transmits its kinetic energy to the rotating bar three 23 through the connecting rod 22 stably connected to the side wall during the rotation. The rotating bar three 23 rotates rapidly and orderly with the bottom of the mounting seat one 7 as the connecting point. At the same time, the rotation of the rotating bar two 21 drives the rotating plate two 24 connected thereto to start to act through the conduction of the connecting rod two 28. The rotating plate two 24 rotates with the connecting point of the bottom of the mounting seat one 7 as the axis to provide stable and accurate assistance for the rising of the coupling 8. Under the coordinated operation of the series of components, the coupling 8 starts to rise slowly, the operator adjusts the rotating handle 27 to match the height of the coupling 8 with the propeller shaft 5, and the relative position between the two is perfect, at this time, all preparations are ready, and the fitting process can be started smoothly.

[0037] Working principle: when the device is used for work, the propeller shaft 5 is placed on the placing seat 17 through the hoisting equipment, then the gear 11 is driven to rotate by starting the motor 9, the rack 12 is pushed to slide through the meshing relationship, and then the sliding plate 30 is pushed to slide outward, so that the rotating plate one 16 is pushed to rotate, the rotating plate one 16 pushes the clamping block 15 to slide to the middle, and then the two sides of the propeller shaft 5 are clamped to achieve the fixing effect, then the pulley 4 is slid on the slide bar 2 to drive the propeller shaft 5 to move to the coupling 8 for fitting machining, when the propeller shaft 5 is close to the coupling 8, the height of the coupling 8 needs to be adjusted, the rotating handle 27 is counterclockwise rotated to drive the screw rod 26 to rotate, and then the fixed block three 29 and the screw rod 26 are connected through threads to shorten the distance between the connecting rod one 25 and the connecting rod two 28, and the rotating bar one 20 and the rotating bar two 21 are pushed to rotate, at the same time, the rotating bar three 23 and the rotating plate two 24 are driven to rotate through the rotation of the connecting rod 22, and then the rising effect of the coupling 8 is achieved, until the adjustment is consistent with the propeller shaft 5, and then the fitting machining can be carried out.
