Description

Technical Field

[0001] This application relates to the field of rotary drum processing equipment, and more specifically, to a high-speed spindle for centrifuge rotary drum processing. Background Technology

[0002] The centrifuge drum is the core component that enables the centrifuge to perform its separation function. Its core function is to use the centrifugal force field generated by high-speed rotation to complete solid-liquid separation, liquid-liquid separation, or multiphase separation of materials. In the precision machining stage of the drum, its outer surface and inner wall need to be ground and polished to meet the accuracy and stability requirements of the equipment operation. This process requires a high-speed spindle to drive the drum to rotate synchronously. During operation, the drum shaft must be precisely clamped into the clamping end of the high-speed spindle. Traditional clamping methods often require a significant amount of time for shaft alignment, thus reducing the overall machining efficiency of the drum. Summary of the Invention

[0003] This application aims to at least solve one of the technical problems existing in the prior art.

[0009] According to this application, the transverse push frame includes a second telescopic member and a first frame.

[0011] High-speed spindles are generally connected to the equipment frame via bearings. However, during long-term operation, the lubricating performance of the internal lubricating oil in the bearings gradually declines. This decline in lubrication performance exacerbates the wear and tear on the bearing components, affecting the stability of the spindle operation. Traditional lubrication maintenance methods require stopping the machine first, then disassembling the protective housing outside the bearing, followed by removing the old lubricating oil and refilling it with new lubricating oil. The entire operation process is cumbersome, time-consuming, and labor-intensive, severely reducing the maintenance efficiency of the equipment.

[0012] According to this application, a lubrication assembly is also included. The lubrication assembly comprises an outer casing, a liquid supply component, a flushing pipe, a liquid extraction component, a waste liquid tank, an oil pressing component, an oil tank, and an oil supply pipe. The outer casings are symmetrically arranged and fixedly connected to the frame. The outer casings are also rotatably and sealed to the rotating spindle. The bearing connecting the rotating spindle to the frame is located between the two symmetrically arranged outer casings. The output end of the liquid supply component delivers cleaning fluid to the flushing pipe, which is fixedly connected to the outer casing. The flushing pipe is located within the... Inside the outer casing and facing the bearing, the liquid extraction component is fixedly connected to the upper part of the waste liquid tank. The liquid extraction component is connected to the bottom of the outer casing and also to the waste liquid tank. The oil pressing component is fixedly connected to one side of the upper part of the outer casing. One end of the oil supply pipe passes through the outer casing and is fixedly connected to the bottom of the oil pressing component. The bottom of the oil tank is inserted into one end of the oil supply pipe and is connected to the oil supply pipe. The output end of the oil supply pipe is located inside the outer casing facing the bearing. The pressure end of the oil pressing component presses out the lubricating oil inside the oil tank. First, lubricating oil diluent is supplied to the outer tank via the fluid supply unit. Once the diluent reaches the set level, the rotating end of the main shaft is controlled to rotate at a low speed, causing the bearings to rotate synchronously in the diluent. During this process, the old lubricating oil inside the bearings is gradually dissolved and diluted by the diluent. Then, the oil extraction unit is activated to extract the mixed waste liquid from the outer tank and inject it into a waste liquid tank. After the initial cleaning, the fluid supply unit injects diluent into the tank again, repeating the above "fluid injection—slow-speed spindle rotation—waste liquid extraction" operation. Through multiple cycles of cleaning, the lubricating oil is thoroughly removed. After the cleaning process, the old lubricating oil remaining inside the bearing is completely drained from the outer casing using a liquid extraction device. Then, new lubricating oil is precisely delivered to both sides of the bearing via an oil supply pipe through an oil pressurizing device. At the same time, the main shaft is kept running at a low speed to ensure that the new lubricating oil can evenly cover all lubrication points inside the bearing, thus completing the lubricating oil replacement operation. This maintenance method relies entirely on mechanized linkage operation, eliminating the need to disassemble the outer casing of the bearing, significantly reducing maintenance time, effectively improving equipment maintenance efficiency, and ensuring the bearing lubrication effect and subsequent operational stability.

[0013] According to this application, the outer casing includes an upper half-casing and a lower half-casing, both of which are sealed and inserted into one side of the frame. The upper half-casing and the lower half-casing are fixedly connected to each other, and the lower half-casing is fixedly connected to the frame. The flushing pipe and the oil supply pipe are both fixedly connected to the upper half-casing, and both the upper half-casing and the lower half-casing are sealed and rotatably connected to the rotating spindle.

[0014] According to this application, the liquid supply component includes a liquid tank and a liquid pump. The output end of the liquid pump is provided with a first liquid pipe, one end of the first liquid pipe is provided with an air inlet pipe, the first liquid pipe is provided with a first solenoid valve, the air inlet pipe is provided with a second solenoid valve, and the first liquid pipe is connected to the flushing pipe.

[0015] According to this application, the liquid extraction component includes an oil extraction tank, a piston plate, and a fourth telescopic component. A three-way pipe is provided on one side of the oil extraction tank. One end of the three-way pipe is connected to the oil extraction tank, and the other end of the three-way pipe is provided with a third solenoid valve and connected to the waste liquid tank. A fourth solenoid valve is provided at the other end of the three-way pipe and connected to the lower half-box. The oil extraction tank is fixedly connected to the upper part of the waste liquid tank. The end of the fourth telescopic component is fixedly connected to the oil extraction tank. The output end of the fourth telescopic component is fixedly connected to one side of the piston plate, and the other side of the piston plate is slidably connected to the inside of the oil extraction tank.

[0016] According to this application, the oil-pressing component includes an outer frame, an oil-pressing rod, and a fifth telescopic component.

[0017] When a high-speed spindle clamps a drum, it usually needs to work in conjunction with a follower shaft to hold the drum between the spindle and the follower shaft. Based on the clamping requirements, both the spindle and the follower shaft need to be equipped with corresponding chuck structures. However, during long-term use, a large amount of oil stains are easily left on the clamping surface of the chuck. If too much oil stains accumulate, it will reduce the clamping friction between the chuck and the drum, which will lead to problems such as displacement and movement of the drum during clamping and subsequent processing, seriously affecting the processing accuracy and operational stability of the drum grinding and polishing.

[0018] According to this application, a cleaning assembly is also included, the cleaning assembly comprising a second linear slide rail, a telescopic frame, a rotating frame, a sleeve, a rotating brush, and a water pump. The sliding end of the second linear slide rail is slidably connected to the frame, the telescopic frame is fixedly connected to the upper part of the sliding end of the second linear slide rail, the telescopic end of the telescopic frame is rotatably connected to the rotating end of the rotating frame, the sleeve is fixedly connected to the rotating end of the rotating frame, the rotating end of the rotating brush is located inside the sleeve, and the output end of the water pump is connected to the upper part of the sleeve. The beneficial effects of the cleaning component during use are as follows: 1. Precise removal of oil stains from the chuck, ensuring clamping stability: The cleaning component can perform targeted cleaning of the chuck parts of the rotating spindle and the follower shaft. During operation, the sliding end of the second linear slide rail drives the telescopic frame, rotating frame, and sleeve to move as a whole. First, the sleeve is precisely fitted onto the outside of one end of the rotating spindle. The cleaning fluid delivered by the water pump is sprayed onto the surface of the chuck through the sleeve. Combined with the rotation and wiping of the rotating brush, the residual oil stains on the clamping surface of the chuck can be quickly and efficiently removed. After the spindle chuck is cleaned, the sleeve is rotated and reversed by the rotating frame. Then, the sleeve is moved and fitted onto one end of the follower shaft by the second linear slide rail. Repeating the cleaning process can complete the removal of oil stains from the follower shaft chuck. This solves the problem of reduced clamping friction caused by oil stain accumulation from the root, ensuring the positioning accuracy when the drum is clamped and avoiding deviation or movement in subsequent processing. 2. Flexible and efficient operation with strong adaptability: The cleaning component achieves flexible horizontal movement through the second linear slide rail. Combined with the telescopic adjustment of the telescopic frame and the steering function of the rotating frame, the position and orientation of the sleeve and rotating brush can be flexibly adjusted. It can precisely adapt to the chuck position of the rotating spindle and follower shaft, completing the cleaning operation without disassembling the chuck or other components, greatly simplifying the cleaning process. Compared to traditional manual cleaning methods, this mechanized cleaning structure not only reduces the intensity of manual operation but also significantly improves cleaning efficiency. It can quickly complete chuck cleaning during the drum processing interval, avoiding excessive processing time spent on cleaning. 3. Ensuring machining accuracy and operational stability, and improving overall machining quality: Effective removal of oil stains from the chuck ensures reliable clamping between the rotating spindle, follower shaft, and drum, guaranteeing high-speed and stable drum rotation and thus ensuring the machining accuracy of the drum grinding and polishing process. Simultaneously, the coordinated design of the cleaning components and spindle components does not interfere with core machining processes such as drum clamping and rotation. While improving cleaning convenience, this further ensures the continuity and stability of the entire machining process, contributing to improved overall machining quality and production efficiency of the centrifuge drum.

[0019] According to this application, the second linear guide rail includes a fourth motor, a second lead screw, and a second slider. The fourth motor is fixedly connected to the frame, and the output end of the fourth motor is fixedly connected to one end of the second lead screw.

The fourth frame and the sixth telescopic member are both fixedly connected to the upper part of the second slider, and the output end of the sixth telescopic member is fixedly connected to the third frame.

[0020] According to this application, the rotating frame includes a fifth frame and a fifth motor. The fifth motor is fixedly connected to the third frame, and the fifth frame is rotatably connected to the third frame. The output end of the fifth motor is fixedly connected to the fifth frame. The sleeve is fixedly connected to the fifth frame. The rotating brush includes a sixth frame, a seventh telescopic member, a sixth motor, a rotating shaft, and a brush head. The sixth frame is slidably connected to the third frame.

The sixth motor is fixedly connected to the inner side of the sixth frame. One end of the rotating shaft is fixedly connected to the output end of the sixth motor, and the other end of the rotating shaft is fixedly connected to the brush head. The rotating shaft is rotatably connected to the third frame and slidably connected to the third frame.

[0021] The advantages of a centrifuge drum machining high-speed spindle according to an embodiment of this application are: 1. Highly efficient and precise clamping and positioning: During operation, the drum can be directly fitted onto the outside of multiple positioning frames. The sliding end of the first linear slide rail drives the follower shaft to move, initially clamping the drum between the follower shaft and the rotating main shaft, ensuring that the drum has a fine adjustment margin. Then, the threaded rod is driven to rotate, driving the second follower frame to move. Through the transmission action of the connecting frame, the positioning frame is pushed to be tensioned synchronously and fit against the inner wall of the drum, automatically completing the centering of the drum. There is no need for repeated manual calibration of the shaft center, which greatly reduces the time cost of clamping and positioning. 2. Balancing clamping stability and rotational adaptability: After the positioning frame completes its centering positioning, the sliding end of the first linear slide rail can further drive the follower shaft to move, firmly clamping the drum to one side of the rotating main shaft; at the same time, the rotational connection between the follower shaft and the sliding end of the first linear slide rail, and the rotational connection between the positioning frame and the first follower frame, can ensure that when the rotating main shaft drives the drum to rotate, the follower shaft can rotate synchronously with the drum, meeting the requirements of the grinding and polishing process for high-speed and stable rotation of the drum, and effectively ensuring processing accuracy; 3. Improve overall processing efficiency: Compared with traditional clamping methods, this solution achieves integrated operation of clamping, centering and tightening through the linkage of mechanical structure, eliminating the tedious manual shaft calibration steps. While ensuring the coaxiality of the drum clamping, it significantly improves the automation level and operation efficiency of drum clamping, thereby improving the overall processing efficiency of the centrifuge drum grinding and polishing process.

Detailed Implementation

[0025] The following description, with reference to the accompanying drawings, describes a high-speed spindle for machining a centrifuge drum according to an embodiment of this application.

[0026] like Figures 1-13 As shown, a high-speed spindle for centrifuge drum machining according to an embodiment of this application includes a frame 100 and a spindle assembly 200.

[0027] The spindle assembly 200 includes a first linear slide rail 210, a follower shaft 220, a rotating spindle 230, a transverse pusher 240, a first follower frame 250, a second follower frame 260, a positioning frame 270, a connecting frame 280, and a drive threaded rod 290. The sliding end of the first linear slide rail 210 is slidably connected to the frame 100. The follower shaft 220 is rotatably connected to the upper part of the sliding end of the first linear slide rail 210. The rotating end of the rotating spindle 230 is connected to the frame 100 via a bearing. The pushing end of the transverse pusher 240 is rotatably connected to the first follower frame 250. 250 is slidably connected to the rotating main shaft 230, the second follower frame 260 is slidably connected to the rotating main shaft 230, and multiple positioning frames 270 and connecting frames 280 are provided at intervals. One side of the positioning frame 270 is rotatably connected to one side of the first follower frame 250, one side of the connecting frame 280 is rotatably connected to the second follower frame 260, and the other side of the connecting frame 280 is rotatably connected to one side of the middle part of the positioning frame 270. One side of the driving end of the driving thread rod 290 is rotatably connected to the first follower frame 250, and the other side of the driving end of the driving thread rod 290 is threadedly connected to the second follower frame 260.

[0028] The following describes, with reference to the accompanying drawings, the working process of a centrifuge drum machining high-speed spindle according to a specific embodiment of this application; Step 1: Initial clamping and positioning of the centrifuge drum; In the initial stage of operation, the operator first places the centrifuge drum to be processed on the outside of the multiple spaced positioning frames 270. Then, the first motor 211 of the first linear slide rail 210 is started. The output end of the first motor 211 drives the first lead screw 212 to rotate on the frame 100. Since the first lead screw 212 is threadedly connected to the first slider 213 and the first slider 213 is slidably engaged with the frame 100, the rotation of the first lead screw 212 is converted into the linear movement of the first slider 213 along the frame 100. This drives the upper support 214 of the first slider 213 and the follower shaft 220 rotatably connected to the support 214 to move synchronously towards the rotating main shaft 230 until the anti-slip block 221 at one end of the follower shaft 220 and the anti-slip block 221 at one end of the shaft 231 of the rotating main shaft 230 together initially clamp the drum. At this time, a certain amount of fine adjustment margin is reserved to provide space for subsequent centering. Step Two: Automatic Centering and Secure Clamping of the Drum: Activate the second telescopic component 241 of the horizontal pusher 240. The output end of the second telescopic component 241 pushes the first frame 242, which is fixedly connected to it, to move. Because the first frame 242 is rotatably connected to the first follower frame 250, and the first follower frame 250 slides along the shaft 231 through the protrusion 251 and the groove 235 of the shaft 231, the first frame 242 drives the first follower frame 250 to slide along the shaft 231 axially to the designated position that matches the drum length. Then, activate the drive threaded rod 29. The third motor 292 drives the fifth gear 295 to rotate. The fifth gear 295 meshes with the outer side of the gear ring 293, thereby driving the gear ring 293 to rotate on the first follower frame 250. Since the inner side of the gear ring 293 meshes with the fourth gear 294 at one end of a plurality of spaced threaded rods 291, the rotation of the gear ring 293 synchronously drives the rotation of all the threaded rods 291. Since one end of the threaded rod 291 is rotatably connected to the first follower frame 250 and the other end is threadedly connected to the second follower frame 260. Furthermore, the second follower frame 260 also slides with the groove 235 of the shaft 231 via the protrusion 251. The rotation of the threaded rod 291 drives the second follower frame 260 to move closer to the first follower frame 250 along the shaft 231. During the movement of the second follower frame 260, the connecting frames 280 rotatably connected to its two sides move synchronously. The end of the connecting frame 280 away from the second follower frame 260 is rotatably connected to the middle of the positioning frame 270, and one side of the positioning frame 270 is rotatably connected to the first follower frame 250. Therefore, the connecting frame... 280 generates an outward thrust on the positioning frame 270, causing the positioning frame 270 to rotate around the hinge point with the first follower frame 250 and gradually tension outward until the outer walls of all positioning frames 270 are completely in contact with the inner wall of the drum, thus achieving automatic centering of the drum; after centering is completed, the first motor 211 of the first linear slide rail 210 is started again, driving the follower shaft 220 to continue moving towards the shaft 231, and the drum is firmly clamped between the follower shaft 220 and the shaft 231 by the squeezing of the two anti-slip blocks 221; Step 3: Drum Rotation Drive and Safety Braking: Start the second motor 232 of the rotating main shaft 230. The output end of the second motor 232 drives the first gear 233 to rotate. The first gear 233 meshes with the second gear 110 on the frame 100. The second gear 110 then meshes with the third gear 234 at one end of the shaft 231. Through the gear set's reduction and torque increase transmission, the power of the second motor 232 is smoothly transmitted to the shaft 231, driving the shaft 231 to rotate at high speed on the frame 100 via bearings. Since the drum is firmly clamped between the shaft 231 and the follower shaft 220, and the follower shaft 220 is rotatably connected to the bracket 214 and the positioning frame 270 is rotatably connected to the first follower frame 250, the shaft 231... The rotation of 31 can synchronously drive the drum and follower shaft 220 to rotate together, meeting the requirements of high-speed and stable rotation for the drum grinding and polishing process. When the grinding and polishing operation is completed or the machine needs to be stopped for adjustment, the locking member 120 on the second gear 110 side of the frame 100 is started. The output end of the first telescopic member 121 of the locking member 120 extends out, pushing the first friction block 122 fixedly connected to it to move towards the second gear 110 side until the first friction block 122 tightly presses against the second friction block 111 on the second gear 110 side. The friction between the two hinders the rotation of the second gear 110, and then the shaft 231 and the drum are gradually decelerated until they stop rotating through the gear set transmission, thus achieving safe braking.

[0029] This significantly improves the automation level and operational efficiency of drum clamping, thereby enhancing the overall processing efficiency of the centrifuge drum grinding and polishing process.

[0030] In addition, a high-speed spindle for centrifuge drum machining according to an embodiment of this application also has the following additional technical features: According to this application, such as Figure 2 As shown, the first linear slide rail 210 includes a first motor 211, a first lead screw 212, and a first slider 213.

[0037] High-speed spindles are generally connected to the equipment frame via bearings. However, during long-term operation, the lubricating performance of the internal lubricating oil in the bearings gradually declines. This decline in lubrication performance exacerbates the wear and tear on the bearing components, affecting the stability of the spindle operation. Traditional lubrication maintenance methods require stopping the machine first, then disassembling the protective housing outside the bearing, followed by removing the old lubricating oil and refilling it with new lubricating oil. The entire operation process is cumbersome, time-consuming, and labor-intensive, severely reducing the maintenance efficiency of the equipment.

[0038] According to this application, such as Figures 7-10 As shown, it also includes a lubrication assembly 300, which includes an outer casing 310, a liquid supply component 320, a flushing pipe 330, a liquid extraction component 340, a waste liquid tank 350, an oil pressing component 360, an oil tank 370, and an oil supply pipe 380. The outer casings 310 are symmetrically arranged and fixedly connected to the frame 100. The outer casings 310 are rotatably and sealed to the rotating spindle 230. The bearing connecting the rotating spindle 230 and the frame 100 is located between the two symmetrically arranged outer casings 310. The output end of the liquid supply component 320 delivers cleaning fluid to the inside of the flushing pipe 330, which is fixedly connected to the outer casing 310. The washing pipe 330 is located inside the outer casing 310 and faces the bearing. The liquid extraction component 340 is fixedly connected to the upper part of the waste liquid tank 350. The liquid extraction component 340 is connected to the bottom of the outer casing 310 and is also connected to the waste liquid tank 350. The oil pressing component 360 is fixedly connected to one side of the upper part of the outer casing 310. One end of the oil supply pipe 380 passes through the outer casing 310 and is fixedly connected to the bottom of the oil pressing component 360. The bottom of the oil tank 370 is inserted into one end of the oil supply pipe 380. The oil tank 370 is connected to the oil supply pipe 380. The output end of the oil supply pipe 380 is located inside the outer casing 310 and faces the bearing. The pressure end of the oil pressing component 360 presses out the lubricating oil inside the oil tank 370. First, the old lubricating oil is diluted and cleaned. The liquid pump 322 of the liquid supply unit 320 is started, drawing out the lubricating oil diluent from the liquid tank 321 and delivering it to the flushing pipe 330 through the first liquid pipe 323. At this time, the first solenoid valve on the first liquid pipe 323 is opened and the second solenoid valve on the air inlet pipe 324 is closed. The diluent is precisely injected into the interior of the outer casing 310 through the flushing pipe 330, which is fixedly connected to the upper half of the outer casing 310 311 and faces the bearing. The bearing is located between the two symmetrical outer casings 310. After the diluent in the tank reaches the set storage level, the main shaft 230 is controlled to rotate at low speed. The bearing rotates synchronously in the diluent, gradually dissolving and diluting the old lubricating oil inside. Then, the waste liquid extraction process begins. The fourth telescopic component 343 of the extraction component 340 is activated, driving the piston plate 342 to slide within the extraction tank 341, generating negative pressure. At this time, the fourth solenoid valve on the three-way pipe 345, connected to the lower half-box 312, opens, while the third solenoid valve connected to the waste liquid tank 350 closes. The old oil mixed with waste liquid in the outer box 310 is sucked into the extraction tank 341 through the three-way pipe 345. Once the extraction tank 341 is full of waste liquid, the fourth telescopic component 343 reverses the piston's rotation. Plate 342 simultaneously closes the fourth solenoid valve and opens the third solenoid valve, pushing the waste liquid into the waste liquid tank 350 for storage. To ensure complete removal of old oil, the above-mentioned cycle operation can be repeated until all residual old oil inside the bearing is completely removed. After the old oil is removed, the new lubricating oil filling process begins. First, the pumping component 340 is activated again to completely remove the remaining diluent in the outer casing 310. Then, the fifth telescopic component 363 of the oil pressurizing component 360 is activated, driving the oil pressurizing rod 362, which is slidably connected to the outer frame 361, to move downwards and apply pressure to the oil tank 370 inserted at one end of the oil supply pipe 380. Pressure is applied to force out the new lubricating oil from the oil drum 370. The new lubricating oil is then transported through the oil supply pipe 380 to the inside of the outer casing 310. The oil supply pipe 380 passes through the upper half of the casing 311 and its output end faces the bearing. At the same time, the rotating main shaft 230 is kept running at a low speed so that the new lubricating oil can evenly cover all lubrication points inside the bearing, completing the entire lubrication and maintenance operation. Throughout the entire process, the upper half of the outer casing 310 311 and the lower half of the casing 312 are sealed and rotated with the rotating main shaft 230, ensuring that there is no liquid leakage during the operation and that there is no need to disassemble the outer casing of the bearing, thus achieving automated and efficient bearing lubrication and maintenance.

[0039] According to this application, such as Figure 8 As shown, the outer casing 310 includes an upper half casing 311 and a lower half casing 312. Both the upper half casing 311 and the lower half casing 312 are sealed and inserted into one side of the frame 100. The upper half casing 311 and the lower half casing 312 are fixedly connected to each other. The lower half casing 312 is fixedly connected to the frame 100. The flushing pipe 330 and the oil supply pipe 380 are both fixedly connected to the upper half casing 311. Both the upper half casing 311 and the lower half casing 312 are sealed and rotatably connected to the rotating main shaft 230.

[0040] According to this application, such as Figure 9As shown, the liquid supply unit 320 includes a liquid tank 321 and a liquid pump 322. The output end of the liquid pump 322 is provided with a first liquid pipe 323. One end of the first liquid pipe 323 is provided with an air inlet pipe 324. The first liquid pipe 323 is provided with a first solenoid valve. The air inlet pipe 324 is provided with a second solenoid valve. The first liquid pipe 323 is connected to the flushing pipe 330.

[0041] According to this application, such as Figure 10 As shown, the liquid extraction component 340 includes an oil extraction tank 341, a piston plate 342, and a fourth telescopic component 343. A three-way pipe 345 is provided on one side of the oil extraction tank 341. One end of the three-way pipe 345 is connected to the oil extraction tank 341, and the other end of the three-way pipe 345 is provided with a third solenoid valve and connected to the waste liquid tank 350. The third solenoid valve is provided at the other end of the three-way pipe 345 and connected to the lower half-box 312. The oil extraction tank 341 is fixedly connected to the upper part of the waste liquid tank 350. The end of the fourth telescopic component 343 is fixedly connected to the oil extraction tank 341. The output end of the fourth telescopic component 343 is fixedly connected to one side of the piston plate 342, and the other side of the piston plate 342 is slidably connected to the inside of the oil extraction tank 341.

[0042] According to this application, such as Figure 7 As shown, the oil pressurizing component 360 includes an outer frame 361, an oil pressurizing rod 362, and a fifth telescopic component 363. The outer frame 361 is fixedly connected to the upper half box 311, the oil pressurizing rod 362 is slidably connected to the outer frame 361, the end of the fifth telescopic component 363 is fixedly connected to the upper half box 311, and the output end of the fifth telescopic component 363 is fixedly connected to the oil pressurizing rod 362.

[0043] When a high-speed spindle clamps a drum, it usually needs to work in conjunction with a follower shaft to hold the drum between the spindle and the follower shaft. Based on the clamping requirements, both the spindle and the follower shaft need to be equipped with corresponding chuck structures. However, during long-term use, a large amount of oil stains are easily left on the clamping surface of the chuck. If too much oil stains accumulate, it will reduce the clamping friction between the chuck and the drum, which will lead to problems such as the drum shifting or moving during clamping and subsequent processing, seriously affecting the processing accuracy and operational stability of the drum grinding and polishing.

[0044] According to this application, such as Figures 11-13 As shown, it also includes a cleaning assembly 400, which includes a second linear slide rail 410, a telescopic frame 420, a rotating frame 430, a sleeve 440, a rotating brush 450, and a water pump 460. The sliding end of the second linear slide rail 410 is slidably connected to the frame 100. The telescopic frame 420 is fixedly connected to the upper part of the sliding end of the second linear slide rail 410. The telescopic end of the telescopic frame 420 is rotatably connected to the rotating end of the rotating frame 430. The sleeve 440 is fixedly connected to the rotating end of the rotating frame 430. The rotating end of the rotating brush 450 is located inside the sleeve 440. The output end of the water pump 460 is connected to the upper part of the sleeve 440. When the cleaning operation starts, the chuck of the rotating spindle 230 is cleaned first. The fourth motor 411 of the second linear guide 410 is started. The output of the fourth motor 411 drives the second lead screw 412 to rotate on the frame 100. Since the second lead screw 412 is threadedly connected to the second slider 413 and the second slider 413 is in sliding engagement with the frame 100, the rotation of the second lead screw 412 is converted into the linear movement of the second slider 413 along the frame 100, which in turn drives the telescopic mechanism fixedly connected to the upper part of the second slider 413. The frame 420, rotating frame 430, and sleeve 440 move synchronously until the sleeve 440 is aligned with the end of the chuck of the rotating spindle 230. Then, the sixth telescopic component 423 of the telescopic frame 420 is activated. The output end of the sixth telescopic component 423 pushes the third frame 421 to slide out along the fourth frame 422, causing the sleeve 440 to approach and accurately fit onto the outside of the chuck of the rotating spindle 230. At the same time, the water pump 460 is activated, and the water pump 460 delivers cleaning fluid to the upper part of the sleeve 440. The cleaning fluid is guided through the inner wall of the sleeve 440. The cleaning fluid is directed onto the clamping surface of the chuck. Then, the seventh telescopic component 452 of the rotating brush 450 is activated, pushing the sixth frame 451 to slide along the third frame 421. This causes the rotating shaft 454 and brush head 455 to move towards the chuck until the brush head 455 contacts the chuck surface. Next, the sixth motor 453 is activated, driving the rotating shaft 454 to rotate the brush head 455. This, combined with the cleaning fluid, wipes away oil stains from the chuck. After the chuck is cleaned by rotating the main shaft 230, the seventh telescopic component 452 drives the brush head 455 to reset. The sixth telescopic component 423 drives the sleeve 440 to reset and disengage from the rotating main shaft 230. Then, the fifth motor 432 of the rotating frame 430 is activated, driving the fifth frame 431 and the sleeve 440 fixedly connected to it to rotate around the third frame 421. This causes the sleeve 440 to turn towards the end where the follower shaft 220 chuck is located. The fourth motor 411 is then activated again, moving the entire cleaning mechanism to one side of the follower shaft 220 via the second linear slide rail 410. The above operation process is repeated to complete the removal of oil stains from the follower shaft 220 chuck. The entire cleaning process requires no disassembly of any parts. Through the flexible adjustment and linkage of each mechanism, precise and efficient cleaning of the two chucks is achieved, ensuring the stability of the subsequent drum clamping.

The fifth motor 432 is fixedly connected to the third frame 421, and the fifth frame 431 is rotatably connected to the third frame 421. The output end of the fifth motor 432 is fixedly connected to the fifth frame 431, and the sleeve 440 is fixedly connected to the fifth frame 431.
