Description

Technical Field

[0001] This invention relates to the field of thread processing technology, specifically to a thread milling device for intelligent machining of ship rudder stock. Background Technology

[0002] In the manufacturing and maintenance of ship rudder stock, the machining quality of the rudder stock threads directly affects the performance and service life of the rudder stock. Before installation, the threads are typically milled at the root to remove excess material, optimize stress distribution, and improve the fatigue strength of the rudder stock. Due to the varying sizes of ships, the dimensions of rudder stocks differ considerably, generally ranging from tens to hundreds of millimeters in diameter. During the milling process, the rudder stock is usually placed horizontally on the ground.

[0003] Currently, traditional rudder post thread milling devices control the milling cutter head to perform milling operations on the thread position through a drive structure. With this control method, it is difficult for the milling cutter to reach into the thread to perform close milling. Some threads will have impurity particles adhering to their interior during later transportation and processing. Existing equipment cannot effectively mill the interior of the thread while simultaneously removing the dust, resulting in unsatisfactory milling effect. Summary of the Invention

[0037] The control components include an annular tube 25 fixedly installed on the side of the lifting platform 2, a first pipe 26 for connecting the annular tube 25 and the adjusting groove 6 on the side of the rotating disk 3, a storage cavity 27 inside the lifting platform 2, a second pipe 28 connected to the annular tube 25 at one end of the storage cavity 27, a control plate 29 slidably connected inside the storage cavity 27, an electric telescopic rod 30 fixedly connected inside the storage cavity 27, the telescopic end of the electric telescopic rod 30 being fixedly connected to the side of the control plate 29, and a limiting component for limiting and fixing on the limiting cylinder 21.

[0038] The limiting component includes a rubber ring 31 fixedly installed on the limiting cylinder 21. A suction cup 32 is provided inside the limiting cylinder 21. The two ends of the suction cup 32 are fixedly connected to the inner walls of the limiting cylinder 21 and the rubber ring 31, respectively. An annular groove 33 communicating with the adjusting groove 6 is provided on the rotating disk 3. 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.

[0039] The milling head also includes a threaded tube 36 fixedly installed at the bottom of the annular box 9. A grinding block 37 is rotatably connected to the outer wall of the milling head 4. A threaded sleeve 38 that is threadedly connected to the threaded tube 36 is rotatably connected to the grinding block 37. A grinding groove 39 is provided at the bottom of the grinding block 37. Multiple sets of side holes 40 that communicate with the insertion tube 12 are provided on the side of the milling head 4. A connecting groove 41 for connecting the side holes 40 and the grinding groove 39 is provided on the grinding block 37.

[0040] The output component includes a storage box 42 fixedly installed at one end of the sliding frame 8. A fourth pipe 43 is provided on the sliding frame 8, which is connected to the storage box 42 and the annular box 9. A fan wheel 44 is fixedly connected inside the rotating box 10. An exhaust filter 45 is fixedly connected to the side of the storage box 42. A second spring 46, which is fixedly connected to the adjusting rod 5, is fixedly connected to the side of the storage box 42.

[0041] Working principle: Adjust the position of the lifting frame 1 to one end of the rudder stick, adjust the height of the lifting platform 2 so that the height of the axis of the rotating disk 3 is consistent with the height of the center of the rudder stick thread, select a suitable combination of milling head 4 and grinding block 37, insert the insertion tube 12 on the milling head 4 into the fixed tube 11, rotate the threaded sleeve 38 to gradually tighten it with the threaded tube 36, and the replacement of the milling head 4 can be completed. At this time, the positions of multiple sets of milling heads 4 and rubber ring 31 are on the same vertical plane, ensuring that when the rubber ring 31 is in contact with one end of the rudder stick, the milling head 4 can just be in contact with one end of the thread.

[0042] The electric telescopic rod 30 is activated and pulled out, causing the control plate 29 to slide within the storage cavity 27. This allows the gas in the suction cup 32 to enter the annular groove 33 and the adjusting groove 6 through the third pipe 35. The gas in the adjusting groove 6 then enters the annular pipe 25 through the first pipe 26 and is drawn into the storage cavity 27 through the second pipe 28. This reduces the air pressure in the suction cup 32 and the adjusting groove 6, allowing the suction cup 32 to firmly hold one end of the rudder post, maintaining the fixed position of the limiting cylinder 21. Simultaneously, the adjusting rods 5 around the perimeter move the sliding frame 8 synchronously towards the outer wall of the rudder post thread until the grinding block 37... When the milling heads 4 are in contact with the outer wall of the rudder stock thread, they will not all enter the thread. Instead, they will be tightly in contact with one end of the rudder stock. When the drive motor 34 is started, the rotating disk 3 will rotate, so that the milling heads 4 will rotate synchronously. When the milling heads 4 rotate to the end of the thread, they will automatically slide into the thread. The multiple milling heads 4 slide into the thread in sequence to achieve the function of automatic guidance, which improves the stability of the milling operation inside the thread. During the time when the milling heads 4 fail to enter the thread, they can grind and mill the root edge of the rudder stock.

[0043] 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 drive rod 24 to rotate. The drive rod 24 drives the drive tube 19 and the drive gear 20 to rotate. The drive gear 20 drives the gear belt 16 to drive the drive roller 15 at both ends to rotate synchronously. The outer wall of the gear belt 16 away from the drive gear 20 is resisted by the adjusting rod 5, ensuring that the gear belt 16 can always mesh with the drive gear 20. The drive roller 15 drives the second gear 18 to drive the first gear 17 to rotate. The first gear 17 drives the rotating box 10 and the fixed tube 11 to rotate, thereby causing the insertion tube 12 and the milling head 4 to rotate and grind. The milling head 4 can rotate and grind along the guide of the rudder stock thread, fully milling the inside of the thread and improving 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.

[0044] During the rotation of the rotating box 10, the impeller 44 will rotate and suck up the gas in the lower insertion pipe 12 and discharge it into the annular box 9 through the connecting hole 14. At this time, the dust inside the thread will be sucked into the insertion pipe 12 through the suction hole 13, while 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 insertion pipe 12. It will then be transported to the storage box 42 through the fourth pipe 43. The gas will be output after being filtered by the exhaust filter 45, and the dust and impurities will be stored in the storage box 42. The exhaust filter 45 can be opened later for cleaning.

[0045] It is worth noting that by setting the transmission between the drive gear 20 and the gear belt 16, the drive tube 19 can always drive the first gear 17 to rotate through the gear belt 16 during the rotation process. When the sliding frame 8 is guided by the milling head 4 and slides in the horizontal direction, it can still maintain a stable transmission relationship, so that the milling head 4 can continuously and stably rotate to mill the root. During the sliding process of the sliding frame 8, the milling head 4 and the grinding block 37 can perform grinding and milling along the outer side of the thread for a certain distance, and the second spring 46 is compressed.

[0046] When the drive motor 34 stops running, the rotating disk 3 stops rotating, and the milling head 4 also stops rotating. At this time, the electric telescopic rod 30 is pushed out in the reverse direction, pushing the gas in the storage chamber 27 into the adjustment groove 6. This allows multiple sets of adjustment rods 5 to slide synchronously in all directions, releasing the clamping state on the rudder stock thread. The second spring 46 rebounds, causing the sliding frame 8 to slide back to its original position. The suction cup 32 releases its adsorption state on the rudder stock, and the lifting frame 1 can be removed.
