[0002] During the manufacturing and maintenance of ship rudder stocks, the quality of the rudder stock thread machining directly impacts their performance and service life. Before installation, the threads are typically milled to remove excess material at the root, optimize stress distribution, and improve the rudder stock's fatigue resistance. Rudder stocks vary greatly in size due to the size of the ship, with diameters typically ranging from tens to hundreds of millimeters.

[0025] The limiting member includes a rubber ring 31 fixedly mounted on the limiting cylinder 21, a suction cup 32 is provided in the limiting cylinder 21, and the two ends of the suction cup 32 are respectively fixedly connected to the inner walls of the limiting cylinder 21 and the rubber ring 31, an annular groove 33 connected to the adjustment groove 6 is provided on the rotating disk 3, and a third pipe 35 for connecting one end of the suction cup 32 with the annular groove 33 is provided on the limiting cylinder 21.

[0026] The root milling part also includes a threaded tube 36 fixedly installed at the bottom of the annular box 9. The outer wall of the root milling head 4 is rotatably connected to a grinding block 37. The grinding block 37 is rotatably connected to a threaded sleeve 38 threadedly connected to the threaded tube 36. A grinding groove 39 is provided at the bottom of the grinding block 37. The side of the root milling head 4 is provided with multiple groups of side holes 40 connected to the plug-in tube 12. The grinding block 37 is provided with a connecting groove 41 for connecting the side holes 40 and the grinding groove 39.

[0027] The output member includes a storage box 42 fixedly mounted on one end of the sliding frame 8, a fourth pipe 43 connected to the storage box 42 and the annular box 9 is opened on the sliding frame 8, a wind wheel 44 is fixedly connected to the rotating box 10, an exhaust filter 45 is fixedly connected to the side of the storage box 42, and a second spring 46 fixedly connected to the adjusting rod 5 is fixedly connected to the side of the storage box 42.

[0028] Working principle: Adjust the position of the lifting frame 1 to one end of the rudder stock, adjust the height of the lifting platform 2 so that the axis height of the rotating disk 3 is consistent with the center height of the rudder stock thread, select a combination of the milling head 4 and the grinding block 37 of appropriate size, insert the plug-in tube 12 on the milling head 4 into the fixed tube 11, rotate the threaded sleeve 38 so that it is gradually tightened with the threaded tube 36, and the milling head 4 can be replaced. At this time, the position of multiple sets of milling heads 4 and the rubber ring 31 are on the same vertical plane to ensure that when the rubber ring 31 conflicts with a section of the rudder stock, the milling head 4 can just conflict with one end of the thread.

[0029] The electric telescopic rod 30 is started to be pulled and pulled, driving the control panel 29 to slide in the storage chamber 27, and the gas in the suction cup 32 enters the annular groove 33 and the adjustment groove 6 through the third pipe 35. The gas in the adjustment groove 6 then enters the annular pipe 25 through the first pipe 26 and is drawn into the storage chamber 27 through the second pipe 28, thereby reducing the air pressure in the suction cup 32 and the adjustment groove 6. The suction cup 32 firmly absorbs one end of the rudder stock to keep the position of the limit cylinder 21 fixed. At the same time, the adjusting rods 5 around it drive the sliding frame 8 to move synchronously toward the outer wall of the rudder stock thread until the grinding block 37 is polished. The plurality of root milling heads 4 are fitted with the outer wall of the rudder shaft thread. At this time, the plurality of root milling heads 4 will not all enter the thread, but will fit tightly with one end of the rudder shaft. Starting the drive motor 34 to drive the rotating disk 3 to rotate can make the plurality of root milling heads 4 rotate synchronously. When the root milling heads 4 rotate to one end of the thread, they will automatically slide into the thread. The plurality of root milling heads 4 slide into the thread in turn to realize the automatic guiding function, thereby improving the stability of the root milling operation inside the thread. During the period when the root milling heads 4 fail to enter the thread, the root milling heads 4 can grind the root end edge of the rudder shaft.

[0030] During the rotation of the rotating disk 3, since the positions of the limiting cylinder 21 and the first bevel gear 22 are relatively fixed, the second bevel gear 23 will roll relative to the first bevel gear 22, thereby driving the driving rod 24 to rotate, and the driving rod 24 drives the driving tube 19 and the driving gear 20 to rotate. The driving gear 20 drives the gear belt 16 to transmit, so that the driving rollers 15 at both ends rotate synchronously, and the outer wall of the gear belt 16 away from the driving gear 20 is resisted by the adjusting rod 5, ensuring that the gear belt 16 can always be meshed with the driving gear 20 for transmission, and the driving roller 15 drives the second gear 18 to drive the first gear 17 to rotate, and the first gear 17 drives the rotating box 10 and the fixed tube 11 to rotate, so that the plug-in tube 12 and the milling head 4 can rotate and grind. The milling head 4 can rotate and grind along the guide of the rudder stock thread, fully mill the inside of the thread, and improve the smoothness of the inside of the thread. At the same time, the grinding block 37 will slide along the outer wall of the rudder stock and grind the external burrs through the grinding groove 39.

[0031] During the rotation of the rotating box 10, the wind wheel 44 will be driven to rotate and suck, and the gas in the lower plug-in tube 12 will be drawn upward and discharged into the annular box 9 through the connecting hole 14. At this time, the dust inside the thread will be drawn into the plug-in tube 12 through the suction hole 13, and the dust in the grinding groove 39 will enter the side hole 40 through the connecting groove 41, and then be transported to the annular box 9 through the plug-in tube 12, and then be transported to the storage box 42 through the fourth pipe 43. The gas is filtered by the exhaust filter 45 and then output, and the dust impurities will be stored in the storage box 42. The exhaust filter 45 can be opened later for cleaning.

[0032] It is worth noting that: by setting up the transmission of the driving gear 20 and the gear belt 16, the driving tube 19 can always drive the first gear 17 to rotate through the gear belt 16 during the rotation process, and when the sliding frame 8 is guided by the root milling head 4 to slide in the horizontal direction, it can still maintain a stable transmission relationship, so that the root milling head 4 can continue to rotate stably to mill the root. During the sliding process of the sliding frame 8, the root milling head 4 and the grinding block 37 can perform grinding and milling along the outside of the thread for a certain distance, and the second spring 46 is compressed.

[0033] When the drive motor 34 stops running, the rotating disk 3 stops rotating, and the root milling head 4 also stops rotating. At this time, the electric telescopic rod 30 is controlled to be pushed out in the opposite direction, pushing the gas in the storage chamber 27 into the adjustment groove 6, so that the multiple groups of adjustment rods 5 can slide synchronously in all directions, releasing the clamping state of the rudder stock thread. The second spring 46 rebounds, causing the sliding frame 8 to slide back to its original position, and the suction cup 32 releases the adsorption state with the rudder stock, and the lifting frame 1 can be removed.
