Description

Technical Field

[0001] This invention relates to the field of wear repair technology, and more specifically to a device for repairing wear on a ring track. Background Technology

[0002] Rotary table filters are solid-liquid separation devices widely used in industries such as chemical, pharmaceutical, and food processing. Their core component, the air distribution disc (also known as the distributor head), is responsible for switching between vacuum and compressed air channels during rotation to achieve filtration, washing, and drying functions. The annular plane of the air distribution disc fits tightly against the fixed end face, relying on high-precision sealing to ensure the airtightness of each process zone. However, due to long-term high-speed rotation friction, media corrosion, or particle intrusion, the annular track is prone to wear, leading to seal failure, gas leakage, reduced process efficiency, and even affecting the normal operation of the equipment.

[0003] CN211388042U discloses a grinding device for repairing the end face of a large bearing ring. The device includes a support plate and several support columns welded and fixed to the bottom of the support plate. It also includes: an L-shaped seat slidably connected above the support plate, with a first slider fixed to the bottom of the L-shaped seat. A first groove is provided in the support plate for the first slider to slide horizontally, and a first drive screw is threaded into the first slider; a support seat slidably connected to the L-shaped seat, sliding along a horizontal plane perpendicular to the sliding direction of the L-shaped seat; a connecting rod hinged to the support seat; and a servo motor mounted and fixed on the connecting rod, with a grinding disc connected to the end of the servo motor's shaft. This device allows the operator to conveniently perform grinding operations on the end face of the bearing ring.

[0004] However, the existing repair methods for grinding devices usually require disassembling the air disc for grinding repair, which is not only time-consuming and labor-intensive, but may also affect the accuracy of the equipment due to reassembly errors, and it is difficult to guarantee the flatness and coaxiality requirements of the repaired surface. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a ring track wear repair device to solve the technical problems of low repair accuracy, low repair efficiency, and the need for reassembly after repair that affects the accuracy of the equipment.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This invention provides a ring track wear repair device, comprising: a guide structure, a support structure, a drive mechanism, and a repair tool. The guide structure is disposed along the outer periphery of the structure to be repaired and is coaxially arranged with the structure to be repaired. The support structure is disposed on the main shaft rotatably connected to the structure to be repaired. The drive mechanism is mounted on the support structure, and the drive end of the drive mechanism is connected to the guide structure for driving the support structure to move circumferentially along the main shaft of the structure to be repaired. The repair tool is connected to the support structure and performs repair processing movement along the circumferential direction of the structure to be repaired as the support structure rotates.

[0007] In some embodiments, the support structure includes a support body, an adjustment drive, and a tool mount. One end of the support body is disposed on a spindle rotatably connected to the structure to be repaired, and the other end extends away from the spindle and is connected to the drive mechanism. The adjustment drive is mounted on the support body, and its drive end is connected to the tool mount for driving the tool mount to move along the length direction of the support body. The tool mount is connected to the repair tool.

[0008] In some embodiments, the tool mount has mounting surfaces on both opposite sides for mounting the repair tool, and the repair tool can be selectively mounted on one of the mounting surfaces, with the grinding surface of the repair tool facing opposite to the mounting surface it is on.

[0009] In some embodiments, the support structure further includes a rolling support member, one end of which is connected to the support body and the other end of which is rolledly connected to one side of the guide structure.

[0010] In some embodiments, the support structure further includes a horizontal adjustment assembly, which includes at least two adjustment members, which are respectively disposed on both sides between the rolling support member and the support body, for independently or synchronously driving the rolling support member to move closer to or further away from the support body.

[0011] In some embodiments, the guide structure includes a plurality of split guide rails, which are arranged around the outer periphery of the structure to be repaired, and are connected in sequence. The outer sides of the plurality of split guide rails form guide ends that are coaxially arranged with the structure to be repaired.

[0012] In some embodiments, the guide structure further includes a plurality of adjusting members. A guide groove is provided on the side of the split guide rail corresponding to the rolling support member. The plurality of adjusting members are respectively provided at the connection of two adjacent split guide rails to adjust the relative position of the guide grooves of the two adjacent split guide rails.

[0013] In some embodiments, the annular track wear repair device further includes a levelness measuring component and a height adjusting component. The height adjusting component has a fixed end and a movable end. The fixed end is connected to the support structure or the repair tool, and its length direction is perpendicular to the working surface of the repair tool. The movable end is connected to the fixed end and can be displaced along the length direction of the fixed end and remain fixed. The levelness measuring component is installed on the movable end and is used to measure the levelness of the surface to be repaired of the structure to be repaired.

[0014] In some embodiments, the support is rotatably connected to the structure to be repaired via a rotating member, the rotating member comprising at least two detachably connected rotating bodies, one of which is connected to the second end, and a rotational space is formed between the rotating bodies to accommodate the main shaft of the structure to be repaired.

[0015] In some embodiments, a rolling element is provided on the side of the rotating body near the rotation space. When the rotating element rotates relative to the main shaft of the structure to be repaired, the rolling element rolls with the main shaft of the structure to be repaired.

[0016] Compared with existing technologies, the annular track wear repair device provided by this invention, through the setting of a guide structure, a support structure, a drive mechanism, and a repair tool, achieves precise positioning through one end of the support structure, and the guide end of the guide structure works in conjunction with the drive mechanism for guidance and drive, ensuring the consistency of the movement trajectory of the repair tool with the worn annular track. This enables the support structure and the repair tool to perform repair processing along the circumference of the structure to be repaired, allowing the repair tool to precisely repair the worn parts of the structure. This device can perform automated, high-precision wear repair processing along the annular track of the structure to be repaired, achieving repair work without disassembling the structure to be repaired, greatly improving repair efficiency and quality. Compared with traditional offline machining methods, this device significantly shortens the maintenance cycle. Furthermore, through the precise alignment of the guide structure and the spindle, and the stable transmission of the drive mechanism, it ensures that the repaired air disc meets the equipment operating requirements, significantly improving the reliability and service life of the turntable filter.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] To address the technical problems of low precision and efficiency in the repair of circular tracks, as well as the impact on equipment precision caused by the need for reassembly after repair, this invention provides a circular track wear repair device. This device can perform automated and high-precision wear repair along the circular track of the structure to be repaired, and can carry out the repair operation without disassembling the structure to be repaired, thus greatly improving repair efficiency and quality.

[0021] It should be noted that the annular track wear repair device described in this invention is used for, but not limited to, grinding and repairing the air distribution plate of a turntable filter. For ease of explanation, this invention will only use the application of the annular track wear repair device to the grinding and repair of the air distribution plate of a turntable filter as an example. The principle of the annular track wear repair device in other types of annular end face repair is essentially the same as that in the grinding and repair of the air distribution plate of a turntable filter, and will not be elaborated here.

[0022] Please see Figure 1 The annular track wear repair device includes: a guide structure 1, a support structure 2, a drive mechanism 3, and a repair tool 4. The guide structure 1 is arranged along the outer periphery of the structure to be repaired 7 and is coaxial with the structure to be repaired 7. The support structure 2 is rotatably connected to the main shaft of the structure to be repaired 7. The drive mechanism 3 is installed on the support structure 2, and the drive end of the drive mechanism 3 is connected to the guide structure 1 for driving the support structure 2 to move circumferentially along the main shaft of the structure to be repaired 7. The repair tool 4 is connected to the support structure 2 and performs repair processing movement along the circumferential direction of the structure to be repaired 7 as the support structure 2 rotates.

[0023] In this device, the guide structure 1 is arranged along the outer periphery of the air disc, and its guide end is coaxial with the structure to be repaired 7, providing a certain positioning reference for the support structure 2. The drive mechanism 3 and the repair tool 4 are both mounted on the support structure 2, providing a reliable support and rotation platform for the drive mechanism 3 and the repair tool 4. Under the transmission cooperation between the drive mechanism 3 and the guide end of the guide structure 1, the support structure 2 and the repair tool 4 can be driven to perform repair processing along the circumference of the structure to be repaired 7, enabling the repair tool 4 to perform precise repair processing on the worn parts of the structure to be repaired 7. This scheme achieves precise positioning through one end of the support structure 2, and guides and drives the drive mechanism 3 in coordination with the guide end of the guide structure 1, ensuring the consistency between the movement trajectory of the repair tool 4 and the circular track of the wear. This allows the repair tool 4 to achieve automated and high-precision wear repair processing along the circular track of the structure to be repaired 7, effectively improving the stability and accuracy of the repair device during the repair process.

[0024] Preferably, please refer to Figures 1 to 5In this embodiment, the support structure 2 consists of a support body 21, an adjustment drive 22, and a tool mounting component 23. The two ends of the support body 21 form a first end and a second end, respectively. The first end is disposed on the spindle rotatably connected to the structure 7 to be repaired, and the second end extends away from the spindle and is connected to the guide structure 1 through the drive mechanism 3. The adjustment drive 22 is mounted on the support body 21, and its drive end is connected to the tool mounting component 23 to drive the tool mounting component 23 to move in the length direction of the support body 21. The tool mounting component 23 is connected to the repair tool 4. Under the drive of the adjustment drive 22, it can drive the repair tool 4 to perform radial position adjustment on the support body 21 to adapt to the repair needs of different positions.

[0025] Please see Figures 1 to 5 In one possible embodiment, the support 21 is a linear guide bracket 211, the adjustment drive 22 includes a first screw 221 and a handle 222, and the tool mounting component 23 adopts a slider structure. A groove is provided on the linear guide bracket 211, and the slider structure is slidably installed in the groove. The first screw 221 passes through the groove, is rotatably connected to the linear guide bracket 211, and is threadedly connected to the slider structure. The handle 222 is connected to one end of the first screw 221 for rotating the first screw 221. Through the threaded engagement between the first screw 221 and the slider structure, the tool mounting component 23 can perform linear displacement along the linear guide bracket 211, thereby driving the repair tool 4 to perform radial position adjustment on the support 21.

[0026] Furthermore, in order to grind and repair the upper and lower annular end faces of the rotary table filter's air distribution plate, please refer to [link to relevant documentation]. Figure 3 and Figure 4 In some possible embodiments, the upper and lower opposing surfaces of the tool mounting member 23 protrude from the linear guide bracket 211, forming mounting surfaces 231 for mounting the repair tool 4. Threaded holes are provided on the mounting surfaces 231, allowing the repair tool 4 to be selectively mounted on one of the mounting surfaces 231 via a threaded connection. The grinding surface of the repair tool 4 faces opposite directions to the mounting surface 231 it occupies. This ensures that when the repair tool 4 is mounted on the upper mounting surface 231, its grinding surface faces downwards, enabling repair processing of the lower annular end face of the air disc. Figure 1 As shown; when the repair tool 4 is installed on the lower mounting surface 231, its grinding surface faces upward, enabling repair machining of the upper annular end face of the air disc, thus improving the versatility and flexibility of the repair device. Furthermore, the threaded connection of the repair tool 4 not only facilitates the replacement of tools of different specifications or wear levels but also ensures the stability and reliability of the tool during machining.

[0027] Of course, in other possible embodiments, the support structure 2 can also adopt other structural forms. For example, the adjustment drive 22 can be driven by a motor-driven lead screw or by a cylinder, hydraulic cylinder, etc. to drive the tool mounting part 23 to move on the support body 21. As long as the purpose of radial position adjustment of the tool mounting part 23 on the support body 21 can be achieved, it is within the protection scope of the present invention.

[0028] To achieve rotational fit between support structure 2 and the structure 7 to be repaired, please refer to... Figure 1 and Figure 4 In some possible embodiments, a rotating element 212 is provided at the end of the linear guide bracket 211 used to connect to the main shaft of the structure to be repaired, so that the first end of the linear guide bracket 211 is rotatably connected to the structure to be repaired 7 through the rotating element 212. Specifically, the rotating element 212 includes two detachably connected semi-annular rotating bodies, one of which is connected to the second end. The two ends of the semi-annular rotating bodies are fixed by bolts or clamping structures, and a rotational space is formed between the two rotating bodies to accommodate the main shaft of the structure to be repaired 7, so as to ensure that the linear guide bracket 211 can rotate stably and flexibly around the main shaft of the structure to be repaired 7. This design not only improves the connection stability between the support structure 2 and the structure to be repaired 7, but also facilitates installation and disassembly, making the repair device more convenient and quick to repair or replace. At the same time, the design of the semi-annular rotating body allows the rotating element 212 to adapt to main shafts of different diameters, further improving the versatility and adaptability of the repair device.

[0029] Further, please refer to Figure 1 and Figure 4 In some possible embodiments, a rolling element 213 is provided on the side of the rotating body near the rotation space. The rolling element 213 can be a ball, a roller or other rolling structure that can reduce friction, so as to reduce the frictional resistance between the rotating body and the main shaft of the structure to be repaired 7. When the rotating element 212 rotates relative to the main shaft of the structure to be repaired 7, the rolling element 213 rolls with the main shaft of the structure to be repaired 7, so that the linear guide bracket 211 rotates more smoothly.

[0030] To further improve the stability and accuracy of the support 21 during its circumferential movement along the structure to be repaired 7, please refer to [link / reference needed]. Figure 1 , Figure 3 , Figure 5 and Figure 6In some possible embodiments, the support structure 2 further includes a rolling support 24. Specifically, the rolling support 24 includes a connecting plate 241, a rolling mounting bracket 242, and rolling elements 243. The rolling elements 243 can be balls, rollers, or other rolling structures that can reduce friction. The connecting plate 241 is connected to the linear guide bracket 211, and the rolling elements 243 are mounted on the connecting plate 241 through a mounting body, enabling them to roll in contact with one side of the guide structure 1. When the linear guide bracket 211 moves circumferentially relative to the main axis of the structure 7 to be repaired, the rolling support 24 can support and position the linear guide bracket 211 to prevent it from shifting or shaking, effectively improving the overall stability and processing accuracy of the repair device during the repair process.

[0031] Further, please refer to Figure 3 , Figure 5 and Figure 6 In some embodiments, the support structure 2 further includes a horizontal adjustment component 25. Two support bodies 21 of the rolling support 24 are provided, located on both sides of the bottom width direction of the linear guide bracket 211. The horizontal adjustment component 25 includes two adjustment members 12, respectively disposed on both sides between the rolling support 24 and the linear guide bracket 211. These adjustment members are used to independently or synchronously drive the rolling support 24 closer to or further away from the support body 21, thereby adjusting the horizontality of the linear guide bracket 211. When used independently, the two adjustment members 12 can adjust the height of both sides of the end of the linear guide bracket 211; when used synchronously, they can adjust the height of the end of the linear guide bracket 211. This allows for slight tilt adjustments of the linear guide bracket 211 to accommodate slight tilts or different height repair requirements of the spindle of the structure 7 to be repaired, further improving the flexibility and adaptability of the repair device during the repair process.

[0032] Preferably, the adjusting component 12 can adopt a threaded adjustment structure, which includes a second screw 251, a sleeve 252 and a rotating sleeve 253. The second screw 251 is rotatably mounted on the rotating sleeve 253, and the rotating sleeve 253 is rotatably connected to the linear guide rail. A handle is provided at the top end of the second screw 251, and the bottom end is threadedly connected to the inside of the sleeve 252. The bottom of the sleeve 252 is rotatably connected to the connecting plate 241. By rotating the handle, the second screw 251 can be driven to move up and down along the sleeve 252, thereby driving the connecting plate 241 and the rolling support 24 to adjust the height relative to the linear guide rail bracket 211.

[0033] To facilitate the installation of the repair device on the outside of the rotary filter's air distribution plate when repairs are needed, and to allow for its removal after repairs are completed, the repair device should be readily available. Preferably, please refer to... Figure 1 and Figure 2In this embodiment, the guide structure 1 includes several separate guide rails 11, which are arranged around the outer periphery of the structure 7 to be repaired. These separate guide rails 11 are connected sequentially and, when combined, form a ring-shaped guide rail structure. During repair, this ring-shaped guide rail structure should be coaxial with the main shaft of the air distribution plate. The outer sides of the multiple separate guide rails 11 together form a guide end coaxially arranged with the structure 7 to be repaired, used to cooperate with the drive mechanism 3 to drive the support structure 2 to rotate circumferentially. By adopting the design of separate guide rails 11, the guide structure 1 can be easily assembled and disassembled, facilitating installation and adjustment during the repair process.

[0034] Further, please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 In one possible embodiment, four split guide rails 11 are provided, and each split guide rail 11 is fixedly mounted with two support columns 14 at its bottom. The four split guide rails 11 are securely installed around the structure 7 to be repaired by the support columns 14. After the repair is completed, the entire guide structure 1 can be quickly disassembled, facilitating equipment maintenance and replacement. At the same time, the number and layout of the split guide rails 11 can also be adjusted according to the actual size and shape of the structure 7 to be repaired, so as to meet the repair needs of the air distribution plate of the rotary table filter of different specifications.

[0035] Furthermore, please refer to Figures 1 to 8 In one possible embodiment, in order to facilitate the rolling support 24 to roll on the guide structure 1, each split guide rail 11 is provided with a guide groove 13. After the split guide rails 11 are combined together, the guide grooves 13 can be interconnected to form a complete annular guide track. One end of the rolling support 24 can be in the guide groove 13 and roll along the guide track.

[0036] In one possible embodiment, a groove and a locking block are respectively provided between two adjacent split guide rails 11. The groove and the locking block cooperate to lock together, so that the two adjacent split guide rails 11 can be tightly connected to form a complete annular guide rail structure. This design also makes the assembly and disassembly of the split guide rails 11 simpler and faster, improving the efficiency of the repair device.

[0037] Please see Figure 1 , Figure 2 , Figure 7 and Figure 8In another possible embodiment, a certain gap is reserved between the upper and lower surfaces of the connection between two adjacent split guide rails 11. The guide structure 1 also includes several adjusting members 12, preferably adjusting bolts. The adjusting bolts are positioned to avoid the guide grooves 13. One end of the adjusting bolt abuts against the connection surface of one of the split guide rails 11, and the other end passes through the connection surface of the adjacent split guide rail 11. By rotating the adjusting bolts, the horizontal position of the guide grooves 13 of the two adjacent split guide rails 11 can be adjusted to ensure that the guide grooves 13 of each split guide rail 11 can form a circular guide track with consistent horizontality after combination, thereby improving the stability and smoothness of the rolling support 24 rolling on the guide track. In addition, the split guide rails 11 connected by adjusting bolts have higher stability, avoiding jamming or deviation of the rolling support 24 on the guide track due to loose connection or inconsistent horizontality between the split guide rails 11, further improving the processing accuracy and stability of the repair device.

[0038] To achieve coordinated guiding and driving between the guide end in guide structure 1 and drive mechanism 3, please refer to... Figure 1 , Figure 3 , Figure 5 , Figure 8 In some possible embodiments, the drive mechanism 3 includes a first motor 31 and a gear 32. The outer sides of the four split guide rails 11 are provided with teeth 15. When multiple split guide rails 11 are combined, the teeth 15 mesh with each other to form a complete ring gear 32 structure. The first motor 31 is mounted on the linear guide rail bracket 211 via a mounting plate. The output shaft of the first motor 31 is connected to the gear 32, which meshes with the teeth 15 on the outer sides of the split guide rails 11. When the first motor 31 starts, the gear 32 begins to rotate under the drive of the motor, tightly engaging with the teeth 15 on the outer sides of the split guide rails 11. This drives the entire guide structure 1, the connected support structure 2, and the repair tool 4 to rotate circumferentially, ensuring that the repair tool 4 can perform precise and stable repair processing along the ring track of the structure 7 to be repaired. Simultaneously, due to the meshing action of the gear 32 and the teeth 15, the drive mechanism 3 has a self-locking function during transmission, effectively preventing accidental rotation caused by external factors, further improving the safety and reliability of the repair device.

[0039] Please see Figures 1 to 3In some possible embodiments, the repair tool 4 includes a mounting base 41, a second motor 42, and a milling cutter 43. The mounting base 41 is bolted to the upper or lower surface of the tool mounting member 23, and one end of the mounting base 41 extends laterally to the outside of the linear guide bracket 211. The second motor 42 is mounted on the extended portion of the mounting base 41, and its output shaft is connected to the milling cutter 43 to drive its rotation. Driven by the second motor 42, the milling cutter 43 can efficiently mill and repair the annular end face of the air disc at high speed, removing material from worn areas and achieving precise repair processing. Combined with the circumferential drive of the guide structure 1 and the drive mechanism 3, it can comprehensively repair the entire annular end face of the air disc, improving the repair quality.

[0040] Furthermore, in some possible embodiments, a height adjustment device can be provided between the second motor 42 and the mounting base 41 to adjust the height of the second motor 42 relative to the mounting base 41, thereby adjusting the position of the milling cutter 43 relative to the annular end face of the structure 7 to be repaired. The height adjustment device may include an adjusting screw and an adjusting nut. One end of the adjusting screw is connected to the second motor 42, and the other end passes through the mounting base 41 and is threaded into the adjusting nut. By rotating the adjusting nut, the distance between the milling cutter 43 and the surface to be repaired can be adjusted.

[0041] Of course, in other possible embodiments, the drive mechanism 3, the repair tool 4, and the height adjustment device can also adopt other structural forms. For example, the drive mechanism 3 can also adopt belt drive or chain drive to adapt to different application scenarios and repair needs. The repair tool 4 can also adopt the structure of grinding wheel, grinding head, etc. to adapt to different repair needs and material properties. The height adjustment device can also adopt hydraulic cylinder, pneumatic cylinder, etc., and the height of the milling cutter 43 can be adjusted by controlling the extension and retraction of the drive element.

[0042] Please see Figure 1 and Figure 9In some possible embodiments, this device also integrates a repair detection function and is equipped with a levelness measuring component and a height adjustment component 5. The height adjustment component 5 has a fixed end 51 and a movable end 52. The fixed end 51 is connected to the support structure 2 or the repair tool 4, and its length direction is perpendicular to the working surface of the repair tool 4. The movable end 52 is connected to the fixed end 51 and can be displaced along the length direction of the fixed end 51 and remain fixed. The levelness measuring component is installed on the movable end 52 and is used to measure the levelness of the surface to be repaired of the structure 7. Since the movable end 52 can be displaced along the length direction of the fixed end 51 and remain fixed, its adjustment can drive the levelness measuring component to move up and down. When measurement is needed, the levelness measuring component can be moved above the surface to be repaired to obtain the levelness data of the surface to be repaired. When measurement is not needed, the levelness measuring component can be moved to a position away from the surface to be repaired to avoid interfering with the repair process. The levelness measuring component can be a dial indicator, laser rangefinder, or other measuring tools, which can accurately measure the levelness of the surface to be repaired and transmit the measurement data to the control system.

[0043] Please see Figure 1 , Figure 5 and Figure 9 In one possible embodiment, the fixed end 51 of the height adjustment member 5 includes a C-clamp 511, a first sleeve 512, a first fixing bolt 513, and a vertical rod 514, while the movable end 52 includes a second sleeve 521 and a second fixing bolt 522. The C-clamp 511 is used to connect the linear guide bracket 211. The tool mounting member 23 and the linear guide bracket 211 are each provided with a horizontal plate 515 at corresponding positions to fix the C-clamp 511. The open end of the C-clamp 511 can be secured to the horizontal plate 515 with bolts. The first sleeve 512 is fixed to one side of the C-clamp 511. Both the first sleeve 512 and the second sleeve 521 are sleeved on the vertical rod 514 and are tightened and loosened respectively by the first fixing bolt 513 and the second fixing bolt 522. The levelness measuring member is fixed to the second sleeve 521. In use, the second clamp 521 can be loosened by rotating the second fixing bolt 522, allowing the movable end 52 to move along the length of the vertical rod 514. After adjusting the horizontal measuring component 6 to a suitable position, the second fixing bolt 522 can be tightened again to fix the movable end 52. Similarly, the first clamp 512 can be loosened or fixed by rotating the first fixing bolt 513, facilitating the overall installation and disassembly of the height adjusting component 5.

[0044] Of course, in other possible embodiments, the height adjustment member 5 may also adopt a structure in which a C-shaped clamp 511 cooperates with a cylinder, an electric telescopic rod or other drive element that can realize the telescopic function. The displacement of the movable end 52 relative to the fixed end 51 is realized by controlling the extension and retraction of the drive element, thereby adjusting the height of the level measuring member.

[0045] To better understand this invention, the following is combined with... Figures 1 to 9 The technical solution of the present invention is described in detail as follows: First, the split guide rail 11 is fixed to the outside of the air-displacement plate of the turntable filter, forming a complete annular guide rail structure around the main shaft of the air-displacement plate. Then, the linear guide rail bracket 211 is installed on the main shaft of the air-displacement plate through the rotating component 212, ensuring that the two semi-annular rotating bodies of the rotating component 212 tightly wrap around the main shaft of the air-displacement plate. Subsequently, the drive mechanism 3 and the repair tool 4 are fixed on the linear guide rail bracket 211, so that the gear 32 meshes with the teeth 15 on the outside of the split guide rail 11, and the position of the milling cutter 43 is adjusted. During repair, the first motor 31 and the second motor 42 are started. The gear 32 starts to rotate under the drive of the motor, driving the entire guide structure 1 and the connected support structure 2 and repair tool 4 to rotate circumferentially. The second motor 42 drives the milling cutter 43 to mill and repair the annular end face of the air-displacement plate at high speed. At the same time, the rolling support component 24 on the support structure 2 rolls in the guide groove 13 of the guide structure 1, ensuring the stability and accuracy of the support structure 2 during rotation. During the repair process, the level of the linear guide bracket 211 can be adjusted by adjusting the level adjustment component 25 to accommodate the slight tilt of the spindle of the structure 7 to be repaired or the repair needs of different heights.

[0046] This invention, through the configuration of a guide structure 1, a support structure 2, a drive mechanism 3, and a repair tool 4, achieves precise positioning via one end of the support structure 2. The guide structure 1, in conjunction with the drive mechanism 3, provides guidance and drive, ensuring the consistency of the repair tool 4's movement trajectory with the worn annular track. This allows the support structure 2 and the repair tool 4 to perform repair processing along the circumference of the structure to be repaired 7, enabling the repair tool 4 to precisely repair the worn areas of the structure 7. This device enables automated, high-precision wear repair processing along the annular track of the structure 7, without disassembling the structure 7, significantly improving repair efficiency and quality. Compared to traditional offline machining methods, this device drastically shortens the maintenance cycle. Furthermore, the precise alignment of the guide structure 1 with the spindle and the stable transmission of the drive mechanism 3 ensure that the repaired air disc meets the equipment's operational requirements, significantly improving the reliability and service life of the turntable filter.
