Detailed Implementation

[0013] 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 scope of protection of the present utility model.

[0014] Please see Figure 1-3 As shown, an intelligent liquid supply and circulation ring polisher includes a housing 1. A PLC controller 2 is mounted on the housing 1 via a fixing bracket. A housing door 3 is mounted on the housing 1. A liquid supply and circulation assembly is mounted on the housing 1. The liquid supply and circulation assembly includes a drain trough 4. The drain trough 4 is opened on the top plate of the housing 1. A drain hopper 401 is installed on the inner wall of the housing 1. A drain component 402 is arranged below the drain hopper 401. A stainless steel screen 403 and a filter element 404 are placed inside the drain component 402. A connecting pipe 405 is installed on the bottom side of the drain component 402. A liquid storage tank 406 is connected to the bottom side of the connecting pipe 405. The liquid storage tank 406 is installed in the housing 1 via a fixing bracket. A pump 407 is mounted on the bottom plate of the housing 1 via a base. A first conduit 408 and a second conduit 409 are installed on the pump 407. The first conduit 408 is connected to the bottom plate of the liquid storage tank 406. The other end of the second conduit 409 is installed... The machine is equipped with a nozzle 410, below which is a spraying element 411. The spraying element 411 has multiple spray holes 412 arranged in a ring on the spraying element 411. A support frame 413 is installed on the housing 1 and is fixedly connected to the nozzle 410. During operation, existing ring polishers require polishing fluid for heat management and debris removal during the grinding and polishing of workpiece 6. Due to the difficulty in recycling the polishing fluid, the recycling rate is poor. By placing workpiece 6 on a polishing disc 507 with the polishing surface facing down, it directly contacts the rotating polishing disc 507. The polishing disc 507 grinds the workpiece 6, and the material is removed through the mechanical action of the abrasive on the polishing disc 507. During this process, a pump 407 (model Grundfos) operates. CM 1-8, the polishing liquid in the storage tank 406 enters the pump 407 through the first conduit 408. The pump 407 guides the polishing liquid into the second conduit 409. Then the polishing liquid is sprayed out from the nozzle 410 and sprayed into the spraying part 411. After that, it flows out from the annularly distributed spray holes 412 and flows onto the polishing disc 507. The polishing liquid continuously flows to the polishing area in a laminar flow form. The function of the polishing liquid is to remove the frictional heat of the polishing area and remove the debris in the polishing area in time. After the polishing fluid carries away the frictional heat and debris from the polishing zone, it flows from the drain tank 4 into the drain hopper 401, and finally into the drain component 402. In the drain component 402, the polishing fluid is filtered sequentially by the stainless steel screen 403 and the filter element 404. The stainless steel screen 403 intercepts large particles such as wear particles from the polishing disc 507 and material flaking off the workpiece 6 generated during the polishing process. The filter element 404 is an Entegris 10K with a precision of 0.1μm, which precisely filters the polishing fluid to maintain its cleanliness. The filtered polishing fluid flows from the connecting pipe 405 of the drain component 402 into the storage tank 406, realizing the filtration and recovery of the polishing fluid and achieving intelligent fluid supply circulation for the ring polisher, which is beneficial to improving the recycling rate of the polishing fluid.

[0015] Please see Figure 4-5As shown, a ring-shaped polishing assembly is installed on the inner wall of the drainage hopper 401 via a connecting frame. The ring-shaped polishing assembly includes a fixing plate 5, which is fixedly connected to the inner wall of the drainage hopper 401 via the connecting frame. A drive motor 501 is installed on the bottom side of the fixing plate 5 via a base. A central shaft 502 is installed on the output shaft of the drive motor 501. A sun gear 503 is fixedly sleeved on the central shaft 502. Three sets of first rotating shafts 504 are rotatably installed on the fixing plate 5. Planetary gears 505 are fixedly sleeved on the first rotating shafts 504. The three sets of planetary gears 505 mesh with the sun gear 503 respectively. A ring gear 506 is rotatably installed on the fixing plate 5. The internal teeth of the ring gear 506 mesh with the external teeth of the three sets of planetary gears 505. The polishing disc 507 is fixedly mounted on the central shaft 502 and is fixedly connected to the spraying component 411. A first pulley 508 is fixedly sleeved on the first rotating shaft 504. Three sets of support plates 509 are installed on the side wall of the fixed plate 5. A rotating rod 510 is rotatably mounted on the support plate 509. A second pulley 511 and a third pulley 512 are fixedly sleeved on the rotating rod 510. A first transmission belt 513 is sleeved on the second pulley 511 and the first pulley 508. The protruding teeth on the inner wall of the first transmission belt 513 mesh with the tooth grooves on the outer edges of the first pulley 508 and the second pulley 511. A limit plate 514 is rotatably connected to the top of the rotating rod 510. The limit plate 514 passes through... The connecting block is fixedly connected to the top plate of the housing 1. A second rotating shaft 515 is rotatably connected to the limiting plate 514. A fourth pulley 516 is fixedly sleeved on the second rotating shaft 515. A second transmission belt 517 is sleeved on the fourth pulley 516 and the third pulley 512. The protruding teeth on the inner wall of the second transmission belt 517 mesh with the tooth grooves on the outer edge of the third pulley 512 and the fourth pulley 516. A drive wheel 518 is fixedly sleeved on the second rotating shaft 515. The surface of the drive wheel 518 is made of rubber. A friction ring 519 is rotatably connected to the limiting plate 514. The inner wall of the friction ring 519 is made of rubber. The friction ring 519 is suspended above the polishing disc 507. A workpiece 6 is placed on the polishing disc 507. During operation, the existing ring polishing machine has difficulty in efficiently polishing the workpiece 6, resulting in poor polishing efficiency. By placing three workpieces 6 on the polishing disc 507 and placing them in the friction ring 519 respectively, the PLC controller 2 drives the drive motor 501 to operate. The drive motor 501 drives the central shaft 502 to rotate, the central shaft 502 drives the sun gear 503 to rotate, the sun gear 503 drives the three planet gears 505 to rotate around their own axis, and the three planet gears 505 drive the ring gear 506 to rotate, thus realizing the stable rotation of the three planet gears 505 around their own axis between the sun gear 503 and the ring gear 506. Three planetary gears 505 drive their own rotating shafts, first shaft 504, to rotate. First shaft 504 drives first pulley 508 to rotate. First pulley 508 drives first transmission belt 513 to rotate. First transmission belt 513 drives second pulley 511 to rotate. Second pulley 511 drives rotating rod 510 to rotate. Rotating rod 510 drives third pulley 512 to rotate. Third pulley 512 drives second transmission belt 517 to rotate. Second transmission belt 517 drives fourth pulley 516 to rotate. Fourth pulley 516 drives second shaft 515 to rotate. Second shaft 515 drives drive wheel 518 on it to rotate. Since the surface of drive wheel 518 is made of rubber and is in contact with the outer wall of friction ring 519, under the action of friction, drive wheel 518 rotates while pushing friction ring 519 to rotate, that is, friction ring 519 rotates stably on limit plate 514. The drive motor 501 operates, which drives the central shaft 502 to rotate. The central shaft 502 drives the polishing disk 507 to rotate. The workpiece 6 is confined within the polishing disk 507. Therefore, relative to the polishing disk 507, the workpiece 6 within the friction ring 519 revolves. Under the action of friction, the polishing disc 507 will cause the workpiece 6 to come into contact with the inner wall of the friction ring 519. The inner wall of the friction ring 519 is made of rubber. Therefore, under the action of friction, the rotating friction ring 519 will push the workpiece 6 to rotate. That is, when the polishing disc 507 polishes the lower surface of the workpiece 6, the workpiece 6 will rotate and revolve. This form can ensure the uniformity of polishing, improve the coverage of polishing trajectory, and this structure can polish multiple workpieces 6, which is conducive to improving the efficiency of polishing workpiece 6.

[0016] Working principle: Existing ring polishing machines have difficulty achieving efficient polishing of workpiece 6 during the grinding and polishing process, resulting in poor polishing efficiency. By placing three workpieces 6 on the polishing disc 507 and placing them in the friction ring 519 respectively, the PLC controller 2 operates, driving the drive motor 501 to operate. The drive motor 501 drives the central shaft 502 to rotate, the central shaft 502 drives the sun gear 503 to rotate, the sun gear 503 drives the three planetary gears 505 to rotate around their own axis, and the three planetary gears 505 drive the ring gear 506 to rotate, thus achieving stable rotation of the three planetary gears 505 around their own axis between the sun gear 503 and the ring gear 506. Three planetary gears 505 drive their own rotating shaft, the first rotating shaft 504, to rotate. The first rotating shaft 504 drives the first pulley 508 to rotate. The first pulley 508 drives the first transmission belt 513 to rotate. The first transmission belt 513 drives the second pulley 511 to rotate. The second pulley 511 drives the rotating rod 510 to rotate. The rotating rod 510 drives the third pulley 512 to rotate. The third pulley 512 drives the second transmission belt 517 to rotate. The second transmission belt 517 drives the fourth pulley 516 to rotate. The fourth pulley 516 drives the second rotating shaft 515 to rotate. The second rotating shaft 515 drives the drive wheel 518 on it to rotate. Because the surface of the drive wheel 518 is made of rubber and is in contact with the outer wall of the friction ring 519, therefore... Under the action of friction, the drive wheel 518 rotates while simultaneously pushing the friction ring 519 to rotate, meaning the friction ring 519 rotates stably on the limiting plate 514. Through the operation of the drive motor 501, the drive motor 501 drives the central shaft 502 to rotate, which in turn drives the polishing disc 507 to rotate. The workpiece 6 is confined within the polishing disc 507; therefore, relative to the polishing disc 507, the workpiece 6 within the friction ring 519 revolves. Under the action of friction, the polishing disc 507 causes the workpiece 6 to contact the inner wall of the friction ring 519. The inner wall of the friction ring 519 is made of rubber; therefore, under the action of friction, the rotating friction ring 519 pushes the workpiece 6 to rotate on its own axis, meaning that the workpiece 6 rotates on its own axis relative to the polishing disc 507. When the lower surface of workpiece 6 is polished, workpiece 6 undergoes both revolution and rotation. This configuration ensures the uniformity of polishing, improves the coverage of the polishing trajectory, and allows for the polishing of multiple workpieces 6, thus enhancing the efficiency of polishing. Existing ring polishing machines require polishing fluid for heat management and debris removal during the polishing process of workpiece 6. Due to the difficulty in recycling the polishing fluid, the recycling rate is poor. By placing workpiece 6 on polishing disc 507 with the polishing surface facing down and in direct contact with the rotating polishing disc 507, the polishing disc 507 grinds the workpiece 6, and the material is removed through the mechanical action of the abrasive on the polishing disc 507.During this process, pump 407 operates; pump 407 is model Grundfos CM. 1-8. The polishing slurry in the storage tank 406 enters the pump 407 through the first conduit 408. The pump 407 guides the polishing slurry into the second conduit 409, and then the polishing slurry is sprayed out from the nozzle 410 into the spraying element 411. After that, it flows out from the annularly distributed spray holes 412 and onto the polishing disc 507. The polishing slurry continuously flows to the polishing area in a laminar flow form. The function of the polishing slurry is to remove the frictional heat of the polishing area and remove the debris in time. After removing the frictional heat and debris from the polishing area, the polishing slurry flows from the drain trough 4 into the drain hopper 401, and finally into the drain element 402. In the drain element 402, the polishing slurry is filtered by the stainless steel screen 403 and the filter element 404 in sequence. The stainless steel screen 403 intercepts large particles such as wear particles from the polishing disc 507 and material flaking off the workpiece 6 generated during the polishing process. The filter element 404 is an Entegris filter. The 10K filter element 404 has a precision of 0.1μm. Filter element 404 precisely filters the polishing slurry, maintaining its cleanliness. The filtered polishing slurry flows from the drain pipe 405 of the drain component 402 into the storage tank 406, achieving filtration and recovery of the polishing slurry. This realizes intelligent liquid supply and circulation for the ring polisher, which helps improve the recycling rate of the polishing slurry.
