Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a ship shafting stern target adjustment device, including a stern tube 24, a stern target body 23 mounted on the outer side of the stern tube 24, and a stern shaft 22 mounted on the inner side of the stern tube 24 and the stern target body 23. The stern tube 24 supports the stern shaft 22, enabling stable operation of the stern shaft 22. The stern target body 23 allows the stern shaft 22 to be smoothly and quickly installed into the stern tube 24, ensuring stable operation of the stern shaft 22 and thus allowing the stern target body 23 to adjust its position. A positioning component is installed on the outside of the tail target body 23. This component enables rapid confirmation of the center point of the tail target body 23, thereby providing a mounting body for the tail shaft 22 and improving work efficiency. The positioning component includes a clamping plate 5, which is installed on the outside of the tail target body 23. A hydraulic rod 4 is installed at the bottom of the clamping plate 5, and a base 1 is fixedly connected to the bottom of the hydraulic rod 4. The base 1 provides support for the hydraulic rod 4, enabling it to operate stably. This allows the hydraulic rod 4 to stably drive the clamping plate 5 to move, thus enabling the clamping plate 5 to position the tail target body 23. The support of the body 23 prevents the tail target body 23 from falling back down during position adjustment. A support column 6 is fixedly connected to the top of the base 1, and an electric push rod 8 is fixedly connected to the outside of the support column 6. A connecting plate 9 is fixedly connected to the end of the electric push rod 8, and a clamping plate 10 is fixedly connected to the outside of the connecting plate 9. A crossbar 7 is fixedly connected to the middle of the support column 6. The base 1 provides support for the support column 6, allowing it to operate stably. This provides better support for the electric push rod 8 and the connecting plate 9, enabling them to operate stably and providing power to the clamping plate 10. This achieves alignment, clamping, and fixing of the tail target body 23, allowing for rapid confirmation of the center point of the tail target body 23. This facilitates subsequent position adjustments of the tail target body 23. Through the cooperation between the various structures of the positioning component, the center point of the tail target body 23 can be quickly confirmed, making position adjustments of the tail target body 23 easier, reducing adjustment time, and improving work efficiency.

[0034] Reference Figures 1-5An electric push rod 11 is fixedly connected to the outer side of the crossbar 7. A connecting plate 12 is fixedly connected to the end of the electric push rod 11. A connecting column 13 is fixedly connected to the top of the connecting plate 12. A clamping plate 14 is fixedly connected to the top of the connecting column 13. The crossbar 7 provides support for the electric push rod 11, allowing it to stably drive the connecting plate 12 and the connecting column 13 to move, thereby moving the clamping plate 10 to achieve centering and clamping of the tail shaft 22. This confirms the center point of the tail shaft 22, facilitating subsequent position adjustment of the tail target body 23. A rotating plate 15 is rotatably connected to the outer periphery of the crossbar 7. An electric push rod 14 is fixedly connected to the outer side of the rotating plate 15. 16. A dial indicator 17 is fixedly connected to the end of the electric push rod 16. The measuring needle tip of the dial indicator 17 contacts the surface of the tail shaft 22. The crossbar 7 provides support for the electric push rod 16, allowing it to stably move the dial indicator 17. This enables the measurement of the position of the tail shaft 22 and the tail target body 23, resulting in more accurate position adjustment of the tail target body 23 and allowing the tail shaft 22 to operate better in the middle of the tail tube 24. A fixing block 20 is fixedly connected to the outer side of the rotating plate 15. A fixing rod 19 is slidably connected to the middle of the fixing block 20. A spring 21 is installed inside the fixing block 20. A fixing hole 18 is opened on the outer side of the crossbar 7. The fixing rod 19 and the fixing hole 18 are interlocked, and the crossbar 7 provides support for the fixing block 20, so that the fixing block 20 can provide stable support for the fixing rod 19, preventing the fixing rod 19 from shifting during operation. The fixing rod 19 can also cooperate with the fixing hole 18 to lock the rotating plate 15, preventing the dial indicator 17 from shifting during measurement and ensuring the accuracy of the measured values. The spring 21 allows the fixing rod 19 to return to its original position after movement. A flange 25 is fixedly connected to the outside of the tail tube 24, and a flange 26 is installed on the outside of the flange 25. The flanges 25 and 26 are connected by threads. A fixing bolt 27 is connected to fix flange 1 25 and flange 26, thereby connecting tail tube 24 and tail target body 23. A fine adjustment screw 28 is threaded in the middle of flange 26. The end of the fine adjustment screw 28 contacts the surface of tail tube 24. By rotating the fine adjustment screw 28, the position of tail target body 23 can be adjusted, making the installation of tail shaft 22 more convenient. A support block 2 is fixedly connected to the bottom of base 1, and an anti-slip pad 3 is fixedly connected to the bottom of support block 2. The cooperation between support block 2 and anti-slip pad 3 provides stable support for base 1, so that base 1 will not shift during operation.

[0035] Working principle: During use, the base 1 is moved below the tail shaft 22 and the tail target body 23. At this time, the hydraulic rod 4 is activated to move the clamping plate 5, so that the clamping plate 5 and the tail target body 23 come into contact and are properly positioned. Then, the electric push rod 8 is activated to move the connecting plate 9, which in turn moves the clamping plate 10, thereby clamping the tail target body 23 and confirming the center point of the tail target body 23. Simultaneously, the electric push rod 11 is activated to move the connecting plate 12, which in turn moves the connecting column 13, which in turn moves the clamping plate 14, thus clamping the tail shaft 22 and confirming the center point of the tail shaft 22.

[0036] The electric push rod 16 is activated to move the dial indicator 17, causing its measuring needle tip to contact the surface of the tail shaft 22. At this time, the fine-tuning screw 28 on the flange 26 is rotated, causing its top to contact the outer side of the tail tube 24, thereby pushing the tail target body 23 to move. This gradually aligns the center of the tail target body 23 with the center of the tail shaft 22, ensuring that the tail shaft 22 is not affected by the tail target body 23 during operation. Simultaneously, the change in the value displayed on the dial indicator 17 is observed. By pulling the fixing rod 19, the fixing rod 19 is disengaged from the fixing hole 18, thus releasing the lock on the rotating plate 15. Rotating the rotating plate 15 then causes the dial indicator 17 to rotate along the surface of the tail shaft 22, thereby measuring the distance between the tail target body 23 and the tail shaft 22. This makes the adjustment of the tail target body 23's position more accurate, ensuring stable operation of the tail shaft 22 without interference from the tail target body 23.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
