Detailed Implementation

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Example 1 Please refer to Figures 1-10 This embodiment provides a centrifugal finishing processing device, including: A frame 1, on which a rotating base 2 is rotatably mounted, the rotating base 2 being driven by a rotary motor 3 to rotate around a first axis; Multiple rollers 4 are rotatably mounted on the top surface of the rotating base 2 and arranged circumferentially. The rotation axis of the rollers 4 is parallel to the first axis. The top of the rollers 4 is provided with an openable and closable sealing cover 5. At least three grinding block receiving cavities 6 are formed inside the rollers 4. A finishing switching mechanism is provided inside the roller 4 and includes multiple workpiece placement components. The multiple workpiece placement components can cooperate with any one of the grinding block receiving cavities 6 to form a processing cavity. A synchronous transmission mechanism is provided inside the rotating base 2, which is used to drive the roller 4 to rotate synchronously in opposite directions with the rotating base 2.

[0021] Specifically, the frame 1 includes four support legs for stable support. The rotating base 2 is mounted on the frame 1 via a rotary bearing. The rotary motor 3 is mounted at the bottom of the frame 1, and its output shaft is connected to the rotating base 2 for transmission, enabling the rotating base 2 to rotate around a first axis; wherein, the first axis is vertical. In this embodiment, the first axis is vertical. Multiple roller seats 36 are provided on the top surface of the rotating base 2, and the roller seats 36 are rotatably connected to the top surface of the rotating base 2, with the rotation axis parallel to the first axis. The roller 4 has an open top end 31 and a closed bottom end. The top end of the roller 4 is provided with a sealing cover 5, and the bottom end of the roller 4 is connected to the rotating base 2 via the roller seat 36. The roller 4 and the roller seat 36 are detachably connected, facilitating the disassembly, cleaning, and replacement of the roller 4. In this embodiment, four rollers 4 are provided and are evenly distributed circumferentially along the top surface of the rotating base 2. The drum 4 is used to hold abrasive blocks and workpieces. Rotation causes relative movement between the abrasive blocks and workpieces for finishing operations. In this embodiment, the drum 4 has three abrasive block receiving cavities 6, which hold abrasive blocks of three different grit sizes. When the rotating base 2 rotates around the first axis, it drives multiple drums 4 to revolve around the first axis. Simultaneously, the drums 4 can also rotate relative to the rotating base 2 via a synchronous transmission mechanism. Furthermore, the direction of rotation of the drums 4 is opposite to the direction of rotation of the rotating base 2. In this embodiment, from a top-down view, the rotating base 2 rotates clockwise, while the multiple drums 4 rotate counterclockwise. This relative rotation causes the abrasive blocks to undergo high-speed centrifugal motion within the drum 4, improving the cutting ability of the abrasive blocks and thus enhancing the efficiency and quality of the finishing process. The finishing switching mechanism includes multiple workpiece placement assemblies, each of which can hold multiple workpieces. The multiple workpiece placement assemblies cooperate with a single grinding block receiving cavity 6 to form a processing cavity inside the drum 4, and a total of three processing cavities can be formed inside the drum 4. In each processing cavity, the workpiece can only be processed by a grinding block of one grit size. By switching the position of the workpiece placement assemblies, the finishing switching mechanism can enable the workpiece to be continuously processed by grinding blocks of different grit sizes in multiple processes, meeting the requirements of different processing stages for grinding block grit size.

[0022] Furthermore, the frame 1 is also provided with a cover assembly, the cover assembly comprising: The movable frame 7 is driven to rise and fall along the first axial direction by a first driving device, and a guide through hole is provided on each side of the movable frame 7; A rotating frame 9 is rotatably mounted on the bottom of the movable frame 7, and the rotation axis of the rotating frame 9 is collinear with the first axis; a mounting part is provided on the rotating frame 9 corresponding to each of the rollers 4, and each mounting part 11 is connected to a sealing cover 5; Two guide rods 10 extend along the first axis and are fixedly connected at one end to the frame 1. The guide rods 10 pass through the guide through hole and can slide relative to the guide through hole.

[0023] Specifically, two guide rods 10 are fixedly installed on the top of the frame 1. The guide rods 10 are arranged vertically. The movable frame 7 is sleeved on the two guide rods 10 through two guide holes, so that the movable frame 7 can be raised and lowered vertically. The raising and lowering of the movable frame 7 is driven by a first driving device 8, which is fixed to the top of the frame 1. The driving end of the first driving device 8 is fixed to the top of the movable frame 7. Optionally, the first driving device 8 is a cylinder. A rotating frame 9 is installed at the bottom of the movable frame 7. The rotating frame 9 is cylindrical and can rotate relative to the movable frame 7. The rotation axis of the rotating frame 9 is collinear with the first axis. In this embodiment, four mounting parts 11 are provided at the bottom of the rotating frame 9 corresponding to the four rollers 4. Therefore, a total of four sealing covers 5 are installed on the rotating frame 9.

[0024] Furthermore, the mounting part 11 includes a first mounting part 11-1 and a second mounting part 11-2. The second mounting part 11 is rotatably mounted on the first mounting part 11-1, and the axis of rotation is perpendicular to the first axis. The bottom of the second mounting part 11-2 is connected to the sealing cover 5 through a self-aligning bearing 12 and two springs 13.

[0025] Specifically, the first mounting part 11-1 is a mounting sleeve fixed on the rotating frame 9. The second mounting part 11-2 is placed inside the first mounting part 11-1 and is coaxially arranged with the first mounting part 11-1. The second mounting part 11-2 and the first mounting part 11-1 are connected by multiple connecting bearings. Through the cooperation of the multiple connecting bearings, the second mounting part 11-2 can rotate relative to the first mounting part 11-1, and the axis of rotation is parallel to the first axis. A self-aligning bearing 12 is installed at the bottom center of the second mounting part 11-2. A spring 13 is set on each of the opposite sides of the self-aligning bearing 12. In the natural state, the springs 13 extend in the vertical direction. The sealing cover 5 is connected to the second mounting part 11-2 through the self-aligning bearing 12 and the two springs 13. The setting of the self-aligning bearing 12 allows the sealing cover 5 to rotate freely relative to the second mounting part 11-2. The two springs 13 can improve the sealing performance when the sealing cover 5 is placed on the roller 4. With the cooperation of the self-aligning bearing 12 and the second mounting part 11-2, the sealing cover 5 can adapt to the roller 4 with errors in height and position, thus achieving a seal.

[0026] When the roller 4 needs to be sealed, the first drive device 8 is activated to control the moving frame 7 to descend so that the sealing cover 5 covers the roller 4; during the processing, the sealing cover 5 is tightly connected to the roller 4, and the rotating frame 9 is set so that the sealing cover 5 can rotate together with the rotating base 2; after the processing is completed, the first drive device 8 is activated to control the moving frame 7 to rise so that the sealing cover 5 opens the roller 4.

[0027] Furthermore, a transmission rod 14 is provided at the center of the top surface of the rotating base 2, and the transmission rod 14 is provided with a plurality of mounting holes; a transmission pin 15 is provided on the rotating frame 9 corresponding to each of the mounting holes, and the transmission pin 15 extends along the first axial direction and is inserted into the mounting hole.

[0028] Specifically, the transmission rod 14 extends along the first axis, and the top of the transmission rod 14 is provided with a transmission disc 43. The transmission disc 43 has four mounting holes evenly distributed around the first axis. Correspondingly, four transmission pins 15 are provided at the bottom of the rotating frame 9. The transmission pins 15 are inserted into the mounting holes and never leave the mounting holes during the lifting and lowering of the moving frame 7. On the one hand, this ensures the alignment of the sealing cover 5 and the roller 4. On the other hand, it can also transmit power to the rotating frame 9 when the rotating base rotates, ensuring the synchronous rotation between the rotating frame 9 and the rotating base 2, as well as between the sealing cover 5 and the roller 4.

[0029] Furthermore, the synchronous transmission mechanism includes: A central rod 16 is coaxially arranged with the rotating base 2, and one end is fixed to the frame 1. A fixed gear 17 is fixed on the central rod 16. Multiple roller shafts 18 are distributed circumferentially along the central rod 16, each roller shaft 18 corresponds to one roller 4, the roller shaft 18 is rotatably connected to the inner wall of the rotating base 2, and a transmission gear 19 is fixedly installed on the roller shaft 18; Multiple transition gears 20 are rotatably connected to the inner wall of the rotating base 2, and the transition gears 20 mesh with the fixed gear 17 and the transmission gear 19 respectively.

[0030] Specifically, one end of the central rod 16 extends from the bottom of the rotating base 2 into its interior, and the other end is fixed to the frame 1. The rotating base 2 can rotate relative to the central rod 16 when it rotates. A fixed gear 17 is mounted on the central rod 16, and the fixed gear 17 is coaxial with and fixed relative to the central rod 16. In this embodiment, the synchronous transmission mechanism includes four roller shafts 18, which are mounted on the inner top wall of the rotating base 2 and rotatably connected to it. The roller shafts 18 penetrate the top of the rotating base 2 and are fixed to the bottom of the roller seat 36. Each roller shaft 18 is equipped with a transmission gear 19 for driving the roller shaft 18 to rotate. Transition gears 20 are used to realize the transmission between the fixed gear 17 and the transmission gears 19. In this embodiment, there are two transition gears 20, and the rotation shafts of the two transition gears 20 are fixed to the inner top wall of the rotating base 2. Each transition gear 20 meshes with the fixed gear 17 and the two transmission gears 19.

[0031] When the rotary motor 3 drives the rotating base 2 to rotate, the rotating base 2 drives two transition gears 20 to rotate around the central rod 16. Since the fixed gear 17 is stationary, the two transition gears 20 drive four transmission gears 19 to rotate, which in turn causes the roller shaft 18 to drive the roller seat 36 and the rollers 4 on the roller seat 36 to rotate. The rollers 4 rotate in the opposite direction to the rotation of the rotating base 2. By setting a synchronous transmission mechanism, while the rotating base 2 drives the four rollers 4 to revolve around the first axis, the four rollers 4 also rotate in the opposite direction to the rotation of the rotating base 2. This combined motion makes the parts and grinding blocks inside the rollers 4 move intensely, enhancing the cutting ability of the grinding blocks.

[0032] Furthermore, the roller 4 is provided with a first spacer sleeve 21 and a second spacer sleeve 22 coaxial with the roller 4. The first spacer sleeve 21 is disposed between the second spacer sleeve 22 and the side wall of the roller 4. At least three grinding block receiving cavities 6 are formed between the first spacer sleeve 21 and the second spacer sleeve 22 and are arranged along the first axis direction. The grinding block particle size contained in the grinding block receiving cavity 6 increases sequentially from one end near the top of the roller 4 to the other end.

[0033] Specifically, the roller 4, the first spacer sleeve 21, and the second spacer sleeve 22 are all cylindrical and coaxially fitted together. The diameter of the first spacer sleeve 21 is smaller than the diameter of the roller 4, and the diameter of the second spacer sleeve 22 is smaller than the diameter of the first spacer sleeve 21. The bottom ends of the first spacer sleeve 21 and the second spacer sleeve 22 are fixedly connected to the bottom of the roller 4. Three grinding block receiving cavities 6 are formed in the annular area between the first spacer sleeve 21 and the second spacer sleeve 22. The three grinding block receiving cavities 6 are separated by a partition plate 37. The partition plate 37 is annular and is mounted on the protrusions on the inner wall of the first spacer sleeve 21 and the outer wall of the second spacer sleeve 22. It can be removed at will. The top surface of the partition plate 37 serves as the bottom surface of the upper grinding block receiving cavity 6, and the bottom surface of the partition plate 37 serves as the top surface of the lower grinding block receiving cavity 6. When the partition plate 37 is placed on the protrusion, the partition plate 37 divides the annular area into different grinding block receiving cavities 6. When the partition plate 37 is removed, the grinding block receiving cavities 6 are connected. In this embodiment, the three grinding block receiving cavities from top to bottom are the first receiving cavity 6-1, the second receiving cavity 6-2, and the third receiving cavity 6-3. The first receiving cavity 6-1 is used to hold fine-grained grinding blocks, the second receiving cavity 6-2 is used to hold medium-grained grinding blocks, and the third receiving cavity 6-3 is used to hold coarse-grained grinding blocks. When processing the workpiece, multiple workpiece placing assemblies are first combined with the third receiving cavity 6-3 to form a processing cavity for rough processing of the workpiece. The workpiece placing assemblies are gradually raised according to the different processing steps, thereby realizing continuous processing of different processes.

[0034] Specifically, multiple workpiece placement assemblies are located in the annular area between the outer wall of the first spacer sleeve 21 and the inner wall of the roller 4, and are evenly arranged along the circumference of the first spacer sleeve 21. The multiple workpiece placement assemblies can move synchronously along the direction of the first axis, and when they move to the outer periphery of different grinding block receiving cavities 6, they cooperate with the corresponding grinding block receiving cavities 6 to form a processing cavity; in this embodiment, there are four workpiece placement assemblies.

[0035] When filling the roller 4 with abrasive blocks, first remove the partition plate 37. Then, add coarse-grained abrasive blocks to the annular area between the first spacer sleeve 21 and the second spacer sleeve 22, stopping when the blocks are close to the first set of protrusions. Next, place the partition plate 37 on the first set of protrusions, and then continue adding medium-grained abrasive blocks, stopping when the medium-grained abrasive blocks are close to the second set of protrusions. Then, place another partition plate 37 on the second set of protrusions and continue adding fine-grained abrasive blocks. To facilitate the removal of the partition plate 37 from the roller 4, hooks are also provided on the top surface of the partition plate 37.

[0036] Furthermore, the sidewall of the first spacer sleeve 21 is provided with a plurality of through holes 23 corresponding to each of the grinding block receiving cavities 6; The optical rectification switching mechanism also includes: At least three spacer plates 24 are disposed between the first spacer sleeve 21 and the side wall of the roller 4, and each spacer plate 24 is disposed on the bottom surface of a grinding block receiving cavity 6. A workpiece receiving cavity 25 is formed between the spacer plate 24, the first spacer sleeve 21, and the inner wall of the roller 4. The workpiece receiving cavity 25 communicates with the grinding block receiving cavity 6 through the through-hole 23. Each spacer plate 24 has a through gap 26 corresponding to a plurality of workpiece placement components. A switching assembly for opening and closing any one and only one through-hole 23 corresponding to the grinding block receiving cavity 6.

[0037] Specifically, the number of spacers 24 is the same as the number of grinding block receiving cavities 6. The spacers 24 are annular plates. All three spacers 24 are set in the annular area between the outer wall of the first spacer sleeve 21 and the inner wall of the roller 4. The three spacers 24 divide the annular area between the first spacer sleeve 21 and the roller 4 into three workpiece receiving cavities 25, namely the fourth receiving cavity 25-1, the fifth receiving cavity 25-2 and the sixth receiving cavity 25-3. The fourth receiving cavity 25-1 and the first receiving cavity 6-1 form a processing cavity, the fifth receiving cavity 25-2 and the second receiving cavity 6-2 form a processing cavity, and the sixth receiving cavity 25-3 and the third receiving cavity 6-3 form a processing cavity. The workpiece placement assembly switches between the three workpiece receiving cavities 25. Each spacer 24 is provided with a gap 26 corresponding to the position of the workpiece placement assembly so that the workpiece placement assembly can shuttle between the three workpiece receiving cavities 25. To ensure communication between the workpiece receiving cavity 25 and the grinding block receiving cavity 6, a set of through-holes 23 are provided on the side wall of the first spacer sleeve 21 corresponding to each grinding block receiving cavity 6. The through-holes 23 are provided so that when the drum 4 rotates, the grinding blocks in the grinding block receiving cavity 6 pass through the through-holes 23 under the action of centrifugal force and enter the corresponding workpiece receiving cavity 25, and are supported by the corresponding spacer plate 24. In this embodiment, each set of through-holes 23 includes three through-holes, which are spaced 120° apart from each other, and the three sets of through-holes 23 coincide in the orthographic projection position on the bottom surface of the drum 4. In order to ensure that only the through-hole 23 corresponding to any processing cavity is opened when the workpiece is in any processing cavity, the finishing switching mechanism also includes a switch assembly. The switch assembly can control any set of through-holes 23 to be opened and only one set is opened. When one set of through-holes 23 is opened, the other two sets are closed to prevent grinding block leakage caused by the two sets of grinding block receiving cavities 6 that do not form processing cavities.

[0038] Specifically, to further improve processing efficiency, the side of the spacer plate 24 that contacts the grinding block is set as an inclined surface, that is, the spacer plate 24 has a structure similar to a frustum cylinder. The end with a smaller diameter is fixed to the outer wall of the first spacer sleeve 21, and the end with a larger diameter is fixed to the inner wall of the drum 4. This arrangement allows the grinding block to rise at the edge of the drum 4 under the cooperation of centrifugal force and the spacer plate 24, thus enabling better contact with the workpiece. On the other hand, after the drum 4 stops rotating, the grinding block can gather into the corresponding grinding block receiving cavity 6, which is convenient for the recycling of the grinding block. To facilitate the recycling of the grinding block, a first discharge port 38 is set in the annular area at the bottom of the drum 4 corresponding to the area between the first spacer sleeve 21 and the second spacer sleeve 22, and a second discharge port 39 is set in the annular area at the bottom of the drum 4 corresponding to the area between the first spacer sleeve 21 and the side wall of the drum 4. The first discharge port 38 and the second discharge port 39 are equipped with controllable valves.

[0039] Furthermore, the switching assembly includes: A drive shaft 27 is disposed inside the second spacer sleeve 22 and its rotation axis is the first axis. The drive shaft 27 is driven to rotate by a drive motor 28. At least three sealing slip rings 29, each of the sealing slip rings 29 corresponding to one of the grinding block receiving cavities 6, the sealing slip rings 29 being embedded in the second spacer sleeve 22 and being rotatable relative to the second spacer sleeve 22, and the inner side of the sealing slip rings 29 being fixedly connected to the drive shaft 27; At least three switch ring plates 30 are provided, each of the switch ring plates 30 is provided corresponding to the first sealing slip ring 29, and the inner side is fixedly connected to the sealing slip ring 29; the switch ring plates 30 are coaxially provided inside the first spacer sleeve 21 and block the through hole 23, and the switch ring plates 30 are provided with openings 31 corresponding to the through hole 23; The openings 31 on the different switch ring plates 30 are staggered so that the through openings 23 of the grinding block receiving cavity 6 are opened when the drive shaft 27 rotates at different angles.

[0040] Specifically, the drive shaft 27 is located inside the second spacer sleeve 22. The drive shaft 27 is arranged along the first axis, with one end penetrating through the bottom of the roller 4 and connected to the output shaft of the drive motor 28, and the other end rotatably mounted on the sealing cap 40. The sealing cap 40 is fixed to the top of the second spacer sleeve 22 and is detachably connected. The sealing cap 40 prevents the grinding blocks from entering the second spacer sleeve 22 when filling the grinding blocks. The second spacer sleeve 22 is divided into multiple sections, including a fixed section and a movable section. The outer wall of the fixed section is fixedly connected to the inner wall of the first spacer sleeve 21 through a fixing rib. The movable section, as a sealing slip ring 29, can rotate relative to the fixed section. In this embodiment, there are three sealing slip rings 29. The three sealing slip rings 29 are axially arranged corresponding to the positions of the three grinding block receiving cavities 6. The inner wall of each sealing slip ring 29 is connected to the drive shaft 27 through multiple first connecting rods 41. Each grinding block receiving cavity 6 is provided with a corresponding switch ring plate 30. The switch ring plate 30 is a tubular structure with the first axis as the axis of rotation. The outer diameter of the switch ring plate 30 matches the inner diameter of the first spacer sleeve 21 so that the outer wall of the switch ring plate 30 is in clearance fit with the inner wall of the first spacer sleeve 21. The inner wall of the switch ring plate 30 is fixedly connected to the outer wall of the corresponding sealing slip ring 29 through the second connecting rod 42. Each switch ring plate 30 has a set of openings 31 on its side wall. Each set of openings 31 includes three openings, and the three openings 31 are spaced 120° apart from each other.

[0041] When the drive motor 28 drives the drive shaft 27 to rotate, the drive shaft 27 drives the sealing slip ring 29 and the switch ring plate 30 to rotate together around the first axis. When the rotation reaches the alignment of a set of through holes 23 and a set of openings 31 corresponding to the same grinding block receiving cavity 6, the grinding block receiving cavity 6 communicates with the corresponding workpiece receiving cavity 25. To control the through holes 23 of the three grinding block receiving cavities 6 to open individually, the openings 31 on the three switch ring plates 30 are offset by 30°. When the drive shaft 27 rotates to the initial position corresponding to 0°, the through holes 23 corresponding to the three grinding block receiving cavities 6 are all closed; when the drive shaft 27 rotates to the first position corresponding to 30°, the through hole 23 corresponding to the third receiving cavity 6-3 is opened, while the through holes 23 corresponding to the first receiving cavity 6-1 and the second receiving cavity 6-2 remain closed; when the drive shaft 27 rotates to the first position corresponding to 60°, the through hole 23 corresponding to the third receiving cavity 6-3 is opened, while the through holes 23 corresponding to the first receiving cavity 6-1 and the second receiving cavity 6-2 remain closed; when the drive shaft 27 rotates to the first position corresponding to 60°, the through holes 23 corresponding to the third receiving cavity 6-3 are ... second receiving cavity 6-1 and the second receiving cavity 6-2 remain closed; when the drive shaft 27 rotates to the first position corresponding to 60°, the through holes 23 corresponding to the third receiving cavity 6-3 are opened, while the through holes 23 corresponding to the third At the second station, the through-hole 23 corresponding to the second receiving cavity 6-2 is opened, and the through-holes 23 corresponding to the first receiving cavity 6-1 and the third receiving cavity 6-3 are closed; when the drive shaft 27 rotates to the third station corresponding to 90°, the through-hole 23 corresponding to the first receiving cavity 6-1 is opened, and the through-holes 23 corresponding to the second receiving cavity 6-2 and the third receiving cavity 6-3 are closed; when the drive shaft 27 continues to rotate 30° from the third station, the through-holes 23 corresponding to the three grinding block receiving cavities 6 are all closed again.

[0042] Furthermore, the workpiece placement assembly includes: A switching seat 32 is slidably mounted on the inner wall of the roller 4 in a direction parallel to the first axis. A sealing plate 33 is provided at the top and bottom of the switching seat 32. When the switching seat 32 slides, it can drive the sealing plate 33 at the bottom to seal the passage gap 26 of the partition plate 24. The receiving frame 34 is installed on the side of the switching seat 32 near the first axis by a rotating device, and the rotation axis is perpendicular to the first axis; the side wall of the receiving frame 34 is provided with multiple holes and a detachable cover plate 35 is provided on one side, and the receiving frame 34 is used to place the workpiece.

[0043] Specifically, the switching seat 32 is fitted with the inner wall of the roller 4 with a clearance and can slide relative to it. The height of the switching seat 32 is adapted to the distance between two adjacent partition plates 24. A sealing plate 33 is provided at the top and bottom of the switching seat 32. The shape of the sealing plate 33 is adapted to the passage gap 26 on the partition plate 24. When the switching seat 32 moves to the corresponding workpiece receiving cavity 25, the two sealing plates 33 on the switching seat 32 seal the passage gap 26 on the bottom partition plate 24 and the passage gap 26 on the top partition plate 24 of the workpiece receiving cavity 25, respectively. This makes the workpiece receiving cavity 25 a sealed space, so that the grinding block moves only in the same processing cavity when the roller 4 rotates.

[0044] The receiving frame 34 is a rectangular frame structure, located between the two sealing plates 33 of the switching seat 32. The receiving frame 34 is hollow inside for placing workpieces. Multiple holes are opened on the side wall of the receiving frame 34 to allow grinding blocks to enter the receiving frame 34 for processing the workpieces during the rotation of the roller 4. A cover plate 35 is provided on the side of the receiving frame 34 near the first axis. The cover plate 35 is detachably connected to the receiving frame 34, which can be selected as a snap-fit ​​or bolt connection. The cover plate 35 facilitates the loading and unloading of workpieces. The receiving frame 34 is rotatably connected to the switching seat 32. The switching seat 32 is driven to rotate by a rotating device embedded in the switching seat 32. Optionally, the rotating device is an embedded motor 50. Driven by the embedded motor 50, when it is necessary to switch the workpiece to different processing chambers, rotating the receiving frame 34 can remove the residual grinding blocks in the receiving frame 34 and allow them to flow along the sealing plates 33 at the bottom of the receiving frame 34 to the grinding block receiving chamber 6.

[0045] Specifically, each switching seat 32 is driven by a set of drive components, including a transmission screw 44, which is located on the outside of the roller 4 and extends in a direction parallel to the first axis. A protective cover 45 is provided on the outside of the transmission screw 44, and the protective cover 45 is detachably connected to the outer wall of the roller 4. One end of the transmission screw 44 is rotatably connected to the protective cover 45, and the other end is connected to a servo motor 46. An adjusting seat 47 is sleeved on the transmission screw 44, and the adjusting seat 47 is threadedly connected to the transmission screw 44. One end of the adjusting seat 47 passes through the outer wall of the roller 4 and is connected to the switching seat 32. A guide groove 48 corresponding to the adjusting seat 47 is provided on the outer wall of the roller 4. The guide groove 48 is used to provide a channel for the connection between the adjusting seat 47 and the switching seat 32, and to guide the movement of the adjusting seat 47. To prevent grinding blocks from entering the protective cover 45 through the guide groove 48 during the rotation of the drum 4, the guide groove 48 is stepped. The guide groove 48 is narrower on the side closer to the transmission screw 44 and has a clearance fit with the adjusting seat 47; the guide groove 48 is wider on the side away from the transmission screw 44 and is provided with a pair of U-shaped sealing lips 49. The pair of U-shaped sealing lips 49 are respectively located on both sides of the adjusting seat 47 and extend in a direction parallel to the first axis. The opening 31 of the U-shaped sealing lips 49 faces away from the inside of the drum 4. The U-shaped sealing lips 49 have a clearance fit with the adjusting seat 47 and are made of elastic and wear-resistant material. Optionally, the U-shaped sealing lips 49 are made of fluororubber. When the servo motor 46 drives the transmission screw 44 to rotate, the transmission screw 44 drives the adjusting seat 47 to adjust in a direction parallel to the first axis, thereby driving the switching seat 32 to move; during the movement of the switching seat 32, the U-shaped sealing lips 49 seal the position of the guide groove 48.

[0046] The processing procedure of the processing equipment provided in this embodiment is as follows: First, the first driving device 8 drives the moving frame 7 to rise so that the sealing cover 5 is separated from the roller 4. Then, grinding blocks of different sizes are filled into different grinding block receiving cavities 6 in sequence. The switching seat 32 is adjusted to the highest position, and the workpiece is placed in the receiving frame 34. Next, the switching seat 32 is adjusted to the position corresponding to the sixth receiving cavity 25-3, and sealed by the cooperation of the partition plate 24 and the sealing plate 33; the first driving device 8 drives the moving frame 7 to move down so that the sealing cover 5 presses down and seals the roller 4; Next, the rotary motor 3 drives the rotating base 2 to rotate, which in turn drives the four rollers 4 to revolve around the first axis. At the same time, the rotation of the rotating base 2 drives the roller shaft 18 to rotate, so that each roller 4 rotates on its own axis, thereby performing finishing on the workpiece in the processing cavity. During the processing, the rotary motor 3 is started and stopped according to the set control strategy, and the workpiece is switched sequentially in different processing cavities. After processing is completed, the first drive device 8 drives the moving frame 7 to rise, thereby causing the sealing cover 5 to separate from the roller 4, and the processed workpiece can be taken out.

[0047] Example 2 Please refer to Figure 11 This embodiment provides a finishing process control method, applied to the centrifugal finishing process equipment as described in Embodiment 1, the method comprising: S100: Obtain the processing information, and call the preset database according to the processing information to obtain the set dwell time and set rotation speed of the workpiece in each workpiece receiving cavity 25; the processing information includes the workpiece type and the grinding block particle size and grinding block material in each grinding block receiving cavity 6.

[0048] Specifically, in step S100, the workpiece type includes information about the workpiece itself, such as its material and shape. The grinding block particle size can be confirmed when the operator fills the grinding block into the grinding block receiving cavity 6. The processing information is input into the equipment by the equipment operator before the equipment starts processing.

[0049] After acquiring the processing information, the equipment calls a preset database based on the processing information. The preset database stores the set dwell time and set rotation speed corresponding to the processing of workpieces of different materials and shapes and abrasive blocks of different grit sizes and materials. According to the scheme of Embodiment 1, a total of three abrasive block receiving cavities 6 are provided. The abrasive blocks in the three abrasive block receiving cavities 6 are of the same material but have different grit sizes. Therefore, three set dwell times and three rotation speeds can be obtained, which are the first dwell time and the first rotation speed corresponding to the sixth receiving cavity 25-3, the second dwell time and the second rotation speed corresponding to the fifth receiving cavity 25-2, and the third dwell time and the third rotation speed corresponding to the fourth receiving cavity 25-1.

[0050] S200: The workpiece is placed in the first workpiece receiving cavity 25 at the bottom by switching seat 32, and the through opening 23 of the grinding block receiving cavity 6 corresponding to the first workpiece receiving cavity 25 is opened so that the first workpiece receiving cavity 25 is connected to the grinding block receiving cavity 6.

[0051] Specifically, in step S200, the workpiece is first placed in the receiving frame 34. Then, the switching seat 32 is controlled to move downwards and move the receiving frame 34 closer to the sixth receiving cavity 25-3, which is the bottommost first workpiece receiving cavity 25. The position of the switching seat 32 is determined by the rotation angle of the servo motor 46. When the switching seat 32 moves into the sixth receiving cavity 25-3 and the two sealing plates 33 on the switching seat 32 seal with the upper and lower passage gaps 26 of the sixth receiving cavity 25-3 respectively, it indicates that the receiving frame 34 has been completely placed in the sixth receiving cavity 25-3. Then, the through opening 23 corresponding to the third receiving cavity 6-3 is opened by the switching assembly, so that the grinding block in the third receiving cavity 6-3 enters the sixth receiving cavity 25-3.

[0052] S300: Control the rotary motor 3 to rotate at a first speed and accumulate the working time of the rotary motor 3; the first speed is the set speed corresponding to the first workpiece receiving cavity 25.

[0053] Specifically, in step S300, after the switching assembly controls the third receiving cavity 6-3 to connect with the sixth receiving cavity 25-3, it controls the rotary motor 3 to start rotating at the first speed; during the rotation of the rotary motor 3, the working time of the rotary motor 3 is monitored to avoid the workpiece being processed in the sixth receiving cavity 25-3 for too long.

[0054] S400: When it is determined that the working time of the rotary motor 3 meets the first duration, the rotary motor 3 is controlled to stop, and the workpiece is moved upward to the second workpiece receiving cavity 25 through the switching seat 32, and the through opening 23 of the grinding block receiving cavity 6 corresponding to the second workpiece receiving cavity 25 is opened; the first duration is the set dwell time corresponding to the lowermost workpiece receiving cavity 25.

[0055] Specifically, in step S400, when it is determined that the working time of the rotary motor 3 has reached the first duration, it indicates that the workpiece has completed the first stage of processing. Then, the rotary motor 3 is controlled to stop working. With the cooperation of the partition plate 24 and the sealing plate 33 below the sixth receiving cavity 25-3, the remaining grinding blocks are removed from the sealing plate 33 to avoid affecting the processing of the workpiece in the next workpiece receiving cavity 25. Afterwards, the switching seat 32 is driven to move upward by the drive assembly so that the receiving frame 34 enters the fifth receiving cavity 25-2, which is the second workpiece receiving cavity 25 in step S400.

[0056] S500: Control the rotary motor 3 to rotate at a second speed and continue for a second duration to complete the processing of the workpiece in the second workpiece receiving cavity 25; the second speed is the set speed corresponding to the second workpiece receiving cavity 25, and the second duration is the set dwell time corresponding to the second workpiece receiving cavity 25.

[0057] Specifically, in step S500, referring to step S200, when the switching seat 32 moves into the fifth receiving cavity 25-2 and the two sealing plates 33 on the switching seat 32 seal with the upper and lower passage gaps 26 of the fifth receiving cavity 25-2 respectively, it indicates that the receiving frame 34 is completely placed in the fifth receiving cavity 25-2; then, the through opening 23 corresponding to the second receiving cavity 6-2 is opened by the switching assembly, allowing the grinding block in the second receiving cavity 6-2 to enter the fifth receiving cavity 25-2; then, the rotary motor 3 is controlled to start rotating at the second speed, and the working time of the rotary motor 3 is monitored. When the rotary motor 3 continues to rotate at the second speed for a second time, it indicates that the workpiece has completed the second stage of processing, and then the rotary motor 3 is controlled to stop working again.

[0058] S600: Continue to move the workpiece up to the next workpiece receiving cavity 25 via the switching seat 32 until the workpiece is processed in all workpiece receiving cavities 25.

[0059] Specifically, in step S600, when the working time of the rotary motor 3 reaches the second duration, it indicates that the workpiece has completed the second stage of processing. Then, the rotary motor 3 is controlled to stop working. With the cooperation of the partition plate 24 and the sealing plate 33 below the fifth receiving cavity 25-2, the remaining grinding blocks are removed from the sealing plate 33, preventing them from affecting the processing of the workpiece in the next workpiece receiving cavity 25. Afterwards, the switching seat 32 is driven upwards by the drive assembly to allow the receiving frame 34 to enter the fourth receiving cavity 25-1. When the switching seat 32 moves into the fourth receiving cavity 25-1 and the two sealing plates 33 on the switching seat 32 seal with the upper and lower passage gaps 26 of the fourth receiving cavity 25-1 respectively, it indicates that the receiving frame 34 is completely placed in the fourth receiving cavity 25-1. Then, the corresponding through-hole 23 of the first receiving cavity 6-1 is opened by the switch assembly, allowing the grinding blocks in the first receiving cavity 6-1 to enter the fourth receiving cavity 25-1. Next, the rotary motor 3 is controlled to start rotating at the third speed, and the working time of the rotary motor 3 is continuously monitored. When the rotary motor 3 rotates at the third speed for the third duration, it indicates that the workpiece has completed the third stage of processing. Then, the rotary motor 3 is controlled to stop working again. At this point, the workpiece has completed the processing in three stages. Finally, the adjusting seat 47 is controlled to drive the switching seat 32 to the highest position, and the processed workpiece can be taken out.

[0060] When the through openings 23 of the first receiving cavity 6-1, the second receiving cavity 6-2, and the third receiving cavity 6-3 are controlled by the switching assembly, the working principle is as follows: Taking the processing of the workpiece in the sixth receiving cavity 25-3 and the movement from the sixth receiving cavity 25-3 to the fifth receiving cavity 25-2 as an example, when the switching seat 32 moves into the sixth receiving cavity 25-3 and the two sealing plates 33 on the switching seat 32 are sealed with the upper and lower passage gaps 26 of the sixth receiving cavity 25-3 respectively, the drive motor 28 is controlled to drive the drive shaft 27 to rotate, so that the drive shaft 27 is switched from the initial position to the first position to open the through port 23 corresponding to the third receiving cavity 6-3, thereby connecting the third receiving cavity 6-3 and the sixth receiving cavity 25-3 to form a processing cavity, ensuring that the grinding block in the third receiving cavity 6-3 can enter the sixth receiving cavity 25-3 when the drum 4 rotates.

[0061] When the switching seat 32 switches between adjacent workpiece receiving cavities 25 from bottom to top, the control rotation device drives the receiving frame 34 to rotate one revolution.

[0062] Specifically, taking the processing of the workpiece in the sixth receiving cavity 25-3 and the movement from the sixth receiving cavity 25-3 to the fifth receiving cavity 25-2 as an example, the rotation angle of the servo motor 46 determines when the receiving frame 34 moves from the sixth receiving cavity 25-3 to the fifth receiving cavity 25-2. The embedded motor 50 is then controlled to drive the receiving frame 34 to rotate, ensuring that the receiving frame 34 rotates 360° before it fully enters the fifth receiving cavity 25-2. This removes any residual grinding blocks in the receiving frame 34 and prevents any residual coarse grinding blocks from entering the fifth receiving cavity 25-2 and affecting subsequent processing efficiency.
