Description

Technical Field

[0001] This invention relates to the field of automated polishing technology for accessories, and in particular to a fully automated grinding device for small accessories. Background Technology

[0002] Currently, small ring-shaped and circular hardware accessories are widely used in the fields of electromechanical transmission, hardware assembly, plumbing, vehicle equipment, lighting and electrical appliances, and pneumatic components. Common components include metal sealing rings, stamped circular gaskets, inner and outer rings of miniature bearings, shaft clip rings, shock-absorbing circular bushings, pipe locking rings, motor limit rings, and anti-wear circular washers. After these small circular and ring-shaped parts are stamped, cut, and machined, burrs, scratches, and surface impurities will remain on the surface. Before assembly and use, the end faces of these accessories must be polished to optimize the surface flatness and avoid assembly scratches and jamming. The industry mainly relies on fully automatic grinding and polishing equipment for small accessories to complete the standardized polishing operation of these small circular and ring-shaped accessories.

[0003] Currently, polishing operations for small ring-shaped and circular parts are mainly divided into two types: manual hand-held abrasive polishing and fully automatic fixed polishing equipment. Conventional automated polishing equipment is equipped with an electric push rod linear push clamping assembly. During operation, the electric push rod feeds linearly and clamps and fixes the outer peripheral wall of the circular ring-shaped part. Relying on the rotation of the matching polishing wheel, the exposed top and bottom surfaces of the part are polished. This type of equipment has a simple structure and low purchase cost, and is widely used by small and medium-sized hardware processing plants for rough polishing of conventional circular ring-shaped parts.

[0004] Currently available electric push rod linear clamping polishing equipment has clamping components that fit snugly against the outer wall of circular annular parts. The inner clamping area, which is completely blocked by the clamping fixture, is outside the polishing range of the grinding wheel, creating a polishing dead zone. After a single clamping and fixing, the equipment can only polish the exposed end face of the part that is not clamped, and cannot complete the full-area polishing of the top and bottom surfaces of the part in one go. To polish the clamped and blocked areas, the polishing equipment must be shut down, and the part must be manually disassembled, flipped, and repositioned. Even with high-end equipment equipped with a robotic arm to assist in flipping, it is still necessary to stop the machine, adjust the workpiece posture, and polish a second time. The entire polishing process cannot be completed continuously and automatically in a closed loop. The process is cumbersome and has many operational breaks. At the same time, the linear push clamping structure cannot be adapted to the centering and clamping of annular parts of different diameters, resulting in poor adaptability and further reducing the efficiency of small-batch polishing. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: Firstly, in this invention, during the application of this technical solution, by setting up a drive module in conjunction with a displacement module, multiple clamping modules can be synchronously opened, closed, and displaced during use. This allows for the adaptation of annular parts with different outer diameters to achieve centered clamping without the need for manual adjustment of the clamping spacing. Combined with a double-sided polishing module, the working position can be adjusted bidirectionally, allowing for the double-sided processing of annular parts with different thicknesses. The clamping module relies on the drive roller to drive the part to rotate, and the clamping points of the part continuously change, thereby achieving the effect that the entire top and bottom surfaces of the part can be polished. The processing process does not require stopping the machine to disassemble and install the part, nor does it require manual or robotic arms to flip the part to adjust the processing angle, reducing processing interruptions.

[0017] Secondly, in this invention, during the application of this technical solution, by setting up a clamping module linked to a cleaning module, the cleaning component can be driven to reciprocate synchronously by the rotation power of the drive roller during use. This allows it to scrape away impurities from the upper and lower surfaces of the parts in real time, following the polishing rhythm, thus avoiding the retention of impurities that affect the polishing operation. The operator can adjust the height of the cleaning component structure to match ring-shaped parts of different thicknesses for close cleaning. The cleaning operation does not require additional drive components; it can complete the linkage impurity removal by relying on the clamping power, reducing the additional energy consumption of the equipment and simplifying the processing procedure of cleaning impurities from the parts separately after polishing.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1 to 8 In this embodiment of the invention, a small-sized fully automatic grinding equipment for accessories includes a base frame 1, with support legs 4 fixedly installed in a triangular arrangement on the top of the base frame 1, a top frame 3 fixedly installed on the top of the support legs 4, and a grinding mechanism 2 fixedly installed on the inner side of the top frame 3. The grinding mechanism 2 includes an annular rail 21, which is fixedly installed on the inner side of the top frame 3. A drive module 22 is provided on one side of the annular rail 21, and displacement modules 23 are fixedly installed at equal intervals along a ring on the outer side of the annular rail 21. Each moving end of the displacement module 23 is fixedly installed with a clamping module 24. The drive module 22 and the displacement module 23 are connected by a transmission. A cleaning module 25 is provided on one of the clamping modules 24. The annular part 27 to be ground is clamped between the inner sides of the clamping modules 24. The cleaning surface and the upper and lower surfaces of the annular part 27 to be polished are attached. A double-sided polishing module 26 is fixedly installed on one side of the drive module 22. The polishing ends of the double-sided polishing module 26 are respectively set at the bottom and top of the annular part 27 to be polished. By setting the polishing mechanism 2 in conjunction with the double-sided polishing module 26, the entire machine is supported by the base frame 1, support legs 4, and top frame 3 during use. The triangularly arranged support legs 4 can distribute the force on the equipment during operation, which can reduce the shaking of the machine body during polishing. The drive module 22, in conjunction with the displacement module 23, drives the clamping module 24 to move in a ring along the annular rail 21. This causes the ring-shaped part 27 to be polished, held by the clamping module 24, to move in a ring simultaneously, changing the clamping contact position between the part and the clamping module 24. Combined with the double-sided polishing modules 26 located above and below the part, the top and bottom surfaces of the part can be polished simultaneously, preventing the formation of polishing obstructions due to a fixed clamping position. A single cleaning module 25, positioned close to the upper and lower surfaces of the part, can simultaneously remove polishing debris and impurities as the part moves, reducing wear caused by debris adhesion. The drive module 22, in unison with multiple displacement modules 23, can simultaneously control the clamping state of multiple clamping modules 24, adapting to the clamping of ring-shaped parts with different outer diameters. This eliminates the need for individual adjustment of each clamping structure, simplifying the part clamping adjustment process. The ring-shaped displacement of the part, combined with simultaneous double-sided polishing, reduces the need for flipping and disassembling the part, shortening the overall polishing time for the ring-shaped part.

[0022] Please see Figures 1-6The drive module 22 includes an inner drive ring 221 and a drive assembly 222. The drive assembly 222 is fixedly installed on one side of the annular rail 21. The inner drive ring 221 is rotatably connected to the inner side of the annular rail 21. The output end of the drive assembly 222 is connected to the inner drive ring 221. A linkage assembly 223 is provided at the bottom of the inner drive ring 221. The outer side of the linkage assembly 223 is connected to each displacement module 23. By setting the drive assembly 222, the inner drive ring 221, and the linkage assembly 223 together, the drive assembly 222 can output power to drive the inner drive ring 221 to rotate along the inner side of the annular rail 21 during use. The inner drive ring 221 can synchronously drive all displacement modules 23 by relying on the linkage assembly 223, which can achieve... The single power unit drives multiple displacement modules 23 to operate synchronously, eliminating the need for independent power control processes. This ensures that all displacement modules 23 move in unison, thereby driving all clamping modules 24 to complete clamping and releasing actions simultaneously. It can uniformly control the clamping position of the annular parts. The linkage component 223 receives the power from the inner drive ring 221 and distributes it to each displacement module 23, ensuring balanced transmission of power and preventing uneven force distribution and movement deviations in individual displacement modules 23. It can stably switch the relative positions of the clamping modules 24, continuously changing the clamping points of the parts in conjunction with subsequent polishing operations, reducing dead angles in the clamping of parts. Relying on the integrated transmission structure to reduce external transmission components, it can reduce the occurrence of equipment transmission jamming.

[0023] Please see Figures 1-6The drive assembly 222 includes a side housing 2221 and an inner annular groove 2222. The side housing 2221 is fixedly connected to one side of the annular rail 21. The inner annular groove 2222 is formed on the outer side of the inner drive ring 221. A drive gear 2223 is rotatably connected to the inner side of the side housing 2221. A gear ring 2224 is fixedly connected to the inner side of the inner annular groove 2222. The drive gear 2223 and the gear ring 2224 are meshed together. A first motor 2225 is fixedly mounted on the bottom of the side housing 2221. The output end of the first motor 2225 is connected to the bottom of the drive gear 2223 through a coupling. By configuring the side housing 2221, drive gear 2223, and gear ring 2224 in conjunction with the first motor 2225, the first motor 2225 outputs power via the coupling during use. The power is directly transmitted to the drive gear 2223. The drive gear 2223 meshes with the gear ring 2224 inside the inner ring groove 2222, which can smoothly transmit the rotational power of the motor to the inner drive ring 221. The side housing 2221 covers the drive gear 2223 and the meshing part, which can prevent polishing debris from entering the meshing gap and avoid debris from jamming the gear and interrupting the transmission. The motor output speed can be directly converted into the rotational motion of the inner drive ring 221. The rotational speed of the inner drive ring 221 can be flexibly adjusted, thereby changing the speed of the clamping module 24's circumferential movement to adapt to different polishing processing needs. The entire meshing transmission structure is arranged on the side of the ring rail 21, without occupying additional processing space in the middle of the equipment, leaving sufficient area to place the ring-shaped parts 27 to be polished.

[0024] Please see Figures 1-6The linkage component 223 includes a connecting ring 2231, which is fixedly connected to the bottom of the inner drive ring 221. An outer ring groove 2232 is formed on the outer side of the connecting ring 2231. A hinge shaft 2233 is rotatably connected to the inner side of the outer ring groove 2232 in a ring-shaped arrangement at equal intervals. A linkage arm 2234 is hinged to the outer ring groove 2232 via the hinge shaft 2233. The outer end of the linkage arm 2234 is hinged to the displacement module 23. By configuring the connecting ring 2231, hinge shaft 2233, and linkage arm 2234, the rotation of the inner drive ring 221 during use can drive the bottom connecting ring 2231 to rotate synchronously. The outer ring groove 2232 limits the movement trajectory of the hinge shaft 2233, allowing the hinge shaft 2233 to follow the connecting ring 2231 in a circular motion. The hinge shaft 2233 drives the linkage arm 2234 to swing and push / pull the displacement module 23 synchronously. This converts the circumferential rotational power of the inner drive ring 221 into linear reciprocating power of the displacement module 23. It can synchronously drive all linkage arms 2234 to swing with the same amplitude, thereby uniformly controlling the movement distance of multiple sets of displacement modules 23. It can synchronously close or open the clamping module 24, conveniently completing the clamping and unloading operation of ring-shaped accessories. The hinge shaft 2233 can rotate autonomously to adapt to the angle change of the linkage arm 2234, which can offset the transmission angle deviation and reduce the transmission resistance when the linkage arm 2234 pushes and pulls the displacement module 23. The overall linkage structure operates as an integrated unit with the inner drive ring 221, and the clamping distance can be adjusted without additional power, simplifying the number of power layouts in the equipment.

[0025] Please see Figures 1-6 The displacement module 23 includes an outer guide rail 231, which is fixedly connected to the outer side of the annular rail 21. A moving block 232 is slidably connected to the inner side of the outer guide rail 231. The bottom of the moving block 232 is rotatably connected to the outer end of the linkage arm 2234. A fixed top arm 233 is fixedly installed on the top of the moving block 232. The clamping module 24 is fixedly connected to the top of the fixed top arm 233. By setting the outer guide rail 231, the moving block 232, and the fixed top arm 233, the linkage arm 2234 can swing to pull the moving block 232 to slide along the inside of the outer guide rail 231 during use. The guide rail 231 limits the sliding path of the moving block 232, which can control the moving block 232 to only perform linear translation. The moving block 232 synchronously drives the top fixed arm 233 to move synchronously. The fixed arm 233 directly drives the clamping module 24 to change position synchronously. The synchronous action of multiple sets of displacement modules 23 can synchronously adjust the relative distance of all clamping modules 24, which can adapt to the ring-shaped parts 27 to be ground with different outer diameter specifications. The moving block 232 is rotatably connected to the end of the linkage arm 2234, which can adapt to the angle change caused by the swing of the linkage arm 2234 and reduce the resistance generated during the sliding process.

[0026] Please see Figures 5-7The clamping module 24 includes a clamping seat 241, which is fixedly installed on the outer end of the fixed top arm 233. A clamping groove 242 is formed on the inner side of the clamping seat 241. Drive rollers 243 are rotatably connected to both ends of the groove 242. A second motor 244 is fixedly connected to one side of the bottom of the clamping seat 241. The output end of the second motor 244 is connected to the lower end of a drive roller 243 via a coupling. By configuring the clamping seat 241, drive rollers 243, and second motor 244, the clamping seat 241 moves synchronously with the fixed top arm 233 during use. The clamping groove 242 can cooperate with the two sets of drive rollers 243 to clamp the object. The outer wall of the annular part 27 is polished. The second motor 244 drives the corresponding drive roller 243 to rotate through the coupling. The rotating drive roller 243 drives the annular part to rotate at a constant speed by the friction of the outer wall. During the rotation of the part, the contact position with the drive roller 243 is constantly changed, which can eliminate the polishing blind spot caused by clamping obstruction. The two sets of drive rollers 243 are symmetrically arranged inside the clamping groove 242, which can stably support and limit the annular part, and prevent the part from shifting and slipping during polishing. The roller body can be driven by a single set of second motors 244, without the need to add additional drive components to drive the part to rotate. This simplifies the clamping and self-rotating structure and reduces the processing energy consumption of the equipment.

[0027] Please see Figures 5-7 A support plate 245 is fixedly connected to the bottom of the clamping base 241. Ball bearings 246 are rotatably connected to the top of the support plate 245 at equal intervals. The overall cross-sectional shape of the clamping groove 242 is V-shaped. The cleaning module 25 is located on the outside of one of the clamping bases 241. By using the support plate 245, ball bearings 246, and V-shaped clamping groove 242, the support plate 245 can lift the ring-shaped part 27 to be polished from the bottom during use, preventing the part from falling downwards during clamping and processing. The ball bearings 246 on the top of the support plate 245 rotate with the bottom surface of the part, reducing the frictional resistance of the bottom surface during the part's rotation and ensuring smooth rotation. The U-shaped clamping groove 242 can be adapted to fit the outer wall of ring-shaped accessories with different outer diameters. In conjunction with the internal drive roller 243 of the clamping groove 242, it can fit and hold the accessories, which can improve the fitting and limiting effect of the accessories. The cleaning module 25 is externally installed on the outside of a single clamping seat 241. It can move and change position synchronously with the clamping seat 241, and can always fit the upper and lower surfaces of the accessories synchronously. It does not occupy the clamping space inside the clamping groove 242, and will not interfere with the clamping of the drive roller 243 or the rotation of the accessories.

[0028] Please see Figures 5-7The cleaning module 25 includes a transmission assembly 251 and a cleaning assembly 252. The transmission assembly 251 is located on the top of the clamping base 241, and the cleaning assembly 252 is fixedly connected to both sides of the clamping base 241. The cleaning assembly 252 is connected to the drive roller 243 via the transmission assembly 251. By setting the transmission assembly 251 and the cleaning assembly 252 to form the cleaning module 25, the cleaning assembly 252 obtains power by relying on the drive roller 243 inside the linkage groove 242 of the transmission assembly 251 during use. It does not require a separate motor to drive the cleaning structure, which can save on the power components of the equipment. Component 251 connects drive roller 243 and cleaning component 252. It can start and stop cleaning component 252 synchronously with drive roller 243, realizing synchronous linkage between polishing and cleaning operations. Cleaning component 252 is assembled on both sides of clamping seat 241 and can move synchronously with clamping seat 241 and annular accessory. It can clean polishing debris in close contact with accessory surface throughout the process, avoiding debris accumulation on accessory polishing contact surface and reducing wear caused by debris on polishing surface. Relying on clamping power linkage cleaning operation, it can eliminate the process of manually cleaning accessory debris separately, simplify the overall processing steps of accessory and improve work efficiency.

[0029] Please see Figures 5-7 The transmission assembly 251 includes a turntable 2511 and a side rail 2512. The turntable 2511 is rotatably connected to the top two sides of the clamping seat 241. The bottom of the turntable 2511 is connected to the top of the drive roller 243 through a coupling. The top of the turntable 2511 is eccentrically rotatably connected to a drive plate 2513. The outer end of the drive plate 2513 is hinged to a movable plate 2514. A long strip-shaped guide groove is opened on the surface of the drive plate 2513. One end of the movable plate 2514 is movably inserted into the guide groove through a sliding shaft. The side rail 2512 is fixedly connected to the two sides of the clamping seat 241. A displacement block 2515 is slidably connected to the inner side of the side rail 2512. The outer side of the displacement block 2515 is connected to the bottom of the movable plate 2514. The cleaning assembly 252 is disposed on the bottom outer side of the displacement block 2515. The cleaning assembly 252 includes a side connecting block 2521, which is fixedly connected to the bottom outer side of the displacement block 2515. A vertical rail 2522 is fixedly installed at the bottom of the side connecting block 2521. Adjusting blocks 2523 are slidably connected to both ends of the vertical rail 2522. A side connecting plate 2524 is fixedly connected to the outer side of the adjusting block 2523. A cleaning brush plate 2525 is fixedly connected to the outer end of the side connecting plate 2524. The cleaning brush surface of the cleaning brush plate 2525 is in contact with the upper and lower surfaces of the annular accessory 27 to be polished. A fixing arm 2526 is fixedly connected to the outer side of the adjusting block 2523. The outer end is threaded with a positioning screw 2527, the end of which passes through the fixed arm 2526. Positioning holes 2528 are linearly arranged at equal intervals on the outer side of the vertical rail 2522. The end of the positioning screw 2527 passes through the fixed arm 2526 and is inserted into the positioning hole 2528. A transmission assembly 251 is formed by a turntable 2511, a drive plate 2513, a movable plate 2514, a side rail 2512, and a displacement block 2515. This is combined with a side connecting block 2521, a vertical rail 2522, an adjusting block 2523, a side connecting plate 2524, a cleaning brush plate 2525, and a fixed arm 2526. 6. The positioning screw 2527 and the positioning hole 2528 form the cleaning assembly 252, so that when in use, the rotation of the drive roller 243 can drive the coaxially connected turntable 2511 to rotate synchronously. The turntable 2511 pulls the drive plate 2513 to swing back and forth. The drive plate 2513, in conjunction with the movable plate 2514, drives the displacement block 2515 to slide back and forth along the side rail 2512. The displacement block 2515 synchronously drives the entire cleaning assembly 252 below to move back and forth, thereby allowing the cleaning brush 2525 to continuously scrape the grinding debris attached to the upper and lower surfaces of the accessories. The operator can slide the adjusting block 2523 on the vertical rail 2522 to change the position. The vertical height of the cleaning brush 2525 is adjusted by rotating the positioning screw 2527 to insert it into the positioning hole 2528 on the surface of the vertical rail 2522 and locking the adjusting block 2523. This allows the brush 2525 to be adjusted to fit different thicknesses of the ring-shaped accessories 27 to be polished. The entire cleaning structure relies on the output power of the drive roller 243 to complete the reciprocating motion. No additional power source is required to drive the cleaning component 252, which reduces the number of motors inside the equipment. The cleaning component 252 moves synchronously with the clamping seat 241 and can be in full contact with the polishing surface of the accessory to clean debris, avoiding debris accumulation at the polishing contact position.

[0030] Please see Figures 1-4 and Figure 8The double-sided polishing module 26 includes a fixed base 261, which is fixedly connected to the middle of one side of the annular rail 21. A first electric cylinder 262 is fixedly connected to the top of the fixed base 261. A movable frame 263 is fixedly installed at the output end of the first electric cylinder 262. A second electric cylinder 264 is fixedly installed at both the top and bottom outer ends of the movable frame 263. An elastic buffer assembly is connected to the output end of the second electric cylinder 264. An inner fixing plate 265 is fixedly installed at the outer end of the elastic buffer assembly. A third motor 266 is fixedly installed at the inner end of the inner fixing plate 265. A polishing wheel 267 is installed at the output end of the third motor 266 by screws. By setting the fixed base 261, the first electric cylinder 262, the movable frame 263, the second electric cylinder 264, the inner fixing plate 265, and the third motor 266 in combination with the polishing wheel 267 to form the double-sided polishing module 26, the first electric cylinder 262 can extend and retract to move the module during use. The frame 263 moves laterally, adjusting the horizontal distance between the polishing wheel 267 and the ring-shaped part 27 to be polished, adapting to polishing operations of parts with different outer diameters. The upper and lower sets of second electric cylinders 264 drive the inner fixing plate 265 to move vertically, adjusting the vertical distance between the upper and lower polishing wheels 267, adapting to ring-shaped parts 27 with different thicknesses to be polished. The third motor 266 drives the polishing wheel 267 to rotate continuously. The upper and lower polishing wheels 267 can simultaneously contact the top and bottom surfaces of the part to complete polishing. The fixed seat 261 is positioned by relying on the ring rail 21, and the polishing operation position will not shift with the ring movement of the clamping module 24. The layered electric cylinders can adjust the horizontal and vertical positions of the polishing wheel 267 separately, adapting to the processing of various specifications of ring-shaped parts without changing the polishing components. The synchronous operation of the upper and lower polishing wheels 267 can complete the double-sided polishing of the part in one go, eliminating the operation step of flipping the part.

[0031] The working principle of this invention is as follows: During application, when the equipment is in use, the first motor 2225 is first regulated to operate. The first motor 2225 drives the drive gear 2223 inside the side housing 2221 to rotate via a coupling. The drive gear 2223 meshes with the gear ring 2224 fixed inside the inner ring groove 2222 for transmission. The gear ring 2224 is forced to drive the inner drive ring 221 to rotate along the inner side of the annular rail 21. The rotation of the inner drive ring 221 synchronously drives the connecting ring 2231 fixed at the bottom to rotate as well. The rotation of the connecting ring 2231 drives the hinge shaft 2233 installed inside the outer ring groove 2232 to move. The hinge shaft 2233, in conjunction with the hinged linkage arm 2234, swings and displaces. The outer end of the linkage arm 2234 pulls the moving block 232 inside the outer guide rail 231 of the displacement module 23 to slide. The sliding block 232 moves synchronously, causing the top fixed arm 233 to move synchronously. The fixed arm 233 directly drives the clamping seat 241 of the clamping module 24 to move synchronously. The operator can control the first motor 2225 to rotate forward and reverse to adjust the sliding stroke of the sliding block 232, thereby uniformly adjusting the opening and closing distance of all clamping seats 241 and adjusting the clamping seat 241 to the fixed opening and closing position. This position allows the operator to place the ring-shaped part 27 to be polished, and at the same time, it can support the ring-shaped part 27 to be polished, preventing the part from falling off the inside of the clamping seat 241 after placement. In subsequent part picking and placing operations, the first motor 2225 can be controlled to reset the clamping seat 241 to the opening and closing position, which facilitates the unloading of polished parts and the rapid loading of new ring-shaped parts 27 to be polished.

[0032] The worker places the ring-shaped part 27 to be ground into the groove 242 of the clamping seat 241. The bottom surface of the part is placed against the ball bearing 246 rotatably connected to the top of the support plate 245. The support plate 245 can support the bottom of the ring-shaped part 27 throughout the process, preventing the part from falling off during processing. The first motor 2225 is started again, which sequentially drives the gear 2223, gear ring 2224, inner drive ring 221, connecting ring 2231, hinge shaft 2233 and linkage arm 2234 to rotate. The linkage arm 2234 pushes the moving block 232 to slide inward along the outer guide rail 231. The moving block 232 drives the fixed top arm 233 and the clamping seat 241 to move inward synchronously, so that the drive rollers 243 rotatably connected to both ends of the groove 242 fit against the outer side of the ring-shaped part 27 to be ground. The wall relies on multiple sets of clamping seats 241 to synchronously gather and complete the centering and limiting clamping of the annular part 27 to be polished. By controlling the first motor 2225 to adjust the sliding range of the moving block 232, the gathering distance of all clamping seats 241 can be changed, which can adapt to the centering clamping of annular parts 27 with different outer diameters. After the part is clamped, the first electric cylinder 262 of the double-sided polishing module 26 is activated. The first electric cylinder 262 extends and retracts, driving the moving frame 263 above the fixed seat 261 to move, thereby adapting to the outer diameter of the part and adjusting the polishing operation position. Then, the second electric cylinders 264 at the upper and lower ends of the moving frame 263 are activated. The second electric cylinders 264 extend and retract, driving the inner fixed plate 265 to move vertically. An elastic buffer assembly composed of a guide rod and a compression spring is provided between the inner fixed plate 265 and the output end of the second electric cylinder 264. After the polishing wheel 267 contacts the surface of the annular part 27 to be polished, the second electric cylinder 264 continues to press down the set stroke, compressing the spring and using the spring's deformation rebound force to keep the polishing wheel 267 in flexible constant pressure contact with the part surface, avoiding rigid overcutting or poor contact caused by part thickness errors. The inner fixing plate 265 drives the third motor 266, starting the third motor 266, which drives the polishing wheel 267 to rotate, so that the top and bottom surfaces of the annular part 27 to be polished can be polished simultaneously. At the same time, the second motor 244 of the clamping module 24 is started. The second motor 244 drives the drive roller 243 on one side of the clamping groove 242 to rotate through the coupling. The drive roller 243 drives the annular part 27 to be polished to rotate inside the multiple sets of drive rollers 243 by the friction of the outer wall. The ball bearings 246 on the top of the bearing plate 245 rotate with the bottom surface of the part, which can reduce the frictional resistance generated during the rotation of the part and ensure the smooth rotation of the part.

[0033] While the drive roller 243 inside the clamping groove 242 rotates, it synchronously drives the turntable 2511, which is rotatably connected to both sides of the top of the clamping seat 241, to rotate coaxially. The turntable 2511 rotates continuously in one direction, causing the eccentrically hinged drive plate 2513 to oscillate in a circular motion. Since the movable plate 2514 passes through the elongated guide groove of the drive plate 2513 via a sliding shaft, when the turntable rotates and generates a radial displacement difference, the sliding shaft slides freely in the guide groove to absorb the radial deviation, thus smoothly linking the movable plate 2514 to move synchronously, completely avoiding interference and jamming of the mechanism at the dead point. The movable plate 2514 drives the displacement block 2515, which is slidably connected to the inner side of the side rail 2512, to slide back and forth. The displacement block 2515 drives the side connecting block 2521, the vertical rail 2522, and the adjusting block 2523 connected at the bottom to move back and forth as a whole, thereby driving the cleaning brush plate 2525 to move back and forth along the upper and lower surfaces of the accessory. The operator can manually slide the adjusting blocks 2523 at both ends of the vertical rail 2522 to adjust the vertical spacing between the two cleaning brush plates 2525. After adjustment, rotate the positioning screw 2527 connected to the outer thread of the fixing arm 2526 and insert the end of the positioning screw 2527 into the corresponding positioning hole 2528 on the outer side of the vertical rail 2522. Lock and fix the position of the adjusting block 2523 to fix the height of the cleaning brush plate 2525. The position of the cleaning brush plate 2525 can be flexibly adjusted according to the different thicknesses of the ring-shaped parts 27 to be polished, so that the cleaning brush plate 2525 always fits the top and bottom surfaces of the parts. The polishing impurities generated by the polishing of the parts can be directly scraped off by the reciprocating cleaning brush plate 2525. The cleaning module 25 operates in linkage with the drive roller 243 and does not require a separate drive structure. It can complete the cleaning of impurities synchronously with the polishing operation, avoiding the accumulation of polishing impurities on the polishing contact surface of the parts.

[0034] As the annular part 27 to be polished continues to rotate along with the drive roller 243, the position where the outer wall of the part is clamped and attached by the drive roller 243 continuously changes. Areas that were originally clamped and blocked from contacting the polishing wheel 267 will rotate to the processing area of ​​the polishing wheel 267 as the part rotates. The upper and lower sets of polishing wheels 267 simultaneously polish both sides of the part, and there are no polishing dead corners on the top and bottom surfaces of the part. After the part rotates several times, the full-area double-sided polishing can be completed. The polishing process does not require shutting down the equipment, manually disassembling and flipping the part, or adjusting the clamping angle of the part with a robotic arm. After the polishing operation is completed, the first motor 2225 is started in reverse to activate all clamping mechanisms. The seat 241 moves outward to release the clamping limit of the accessory, and the staff can directly remove the polished accessory. This device uses a single first motor 2225 to link all displacement modules 23 to move synchronously. The clamping opening and closing size can be uniformly adjusted, and it can be used to clamp various outer diameter ring-shaped accessories in the center. The cleaning brush plate can be manually adjusted to adapt to accessories of various thicknesses for linkage impurity removal. The accessory rotates and dynamically switches the clamping point. With double-sided synchronous polishing, the flipping process is eliminated, shortening the overall processing time of the accessory. The linkage cleaning structure cleans and polishes impurities simultaneously, reducing the impact of impurities on the polished surface. The entire processing process only requires manual loading and unloading, reducing manual intervention steps.

[0035] A PLC controller is fixedly mounted on the side of the base frame 1 of this device. The PLC controller centrally manages the operating status of all motors and cylinders in the equipment. A linear displacement sensor can be configured on the side of the outer guide rail 231. The linear displacement sensor collects the lateral sliding distance of the moving block 232 in real time and transmits the signal to the PLC controller, which can control the opening and closing stroke of the clamping seat 241. At the same time, an angle sensor can be configured on the outside of the side housing 2221. The angle sensor collects the rotation angle and speed data of the drive gear 2223 in real time and transmits it synchronously to the PLC controller. The PLC controller adjusts the output speed and number of rotations of the first motor 2225 according to the received data, thereby controlling the synchronous closing or expansion of multiple clamping modules 24. A pressure sensor can be configured at the connection position between the fixed top arm 233 and the clamping seat 241. The pressure sensor detects the overall clamping pressure generated when the clamping seat 241 closes inward in real time. After the pressure value reaches the preset range, it sends a signal to the PLC controller, which then cuts off the output power of the first motor 2225 to complete the centering clamping limit of the accessory. Linear displacement sensors are respectively configured on the sides of the movable frame 263 and the inner fixed plate 265. The sensors collect the telescopic displacement data of the first electric cylinder 262 and the second electric cylinder 264 and transmit it to the PLC controller. The PLC controller adjusts the telescopic length of the electric cylinders according to the data to match the polishing position of different specifications of accessories. An angle sensor can be configured on the side of the top turntable 2511 of the clamping seat 241. The sensor collects the rotation angle signal of the turntable 2511 and transmits it to the PLC controller. The PLC controller matches the operating speed of the second motor 244 based on the signal and adjusts the reciprocating cleaning frequency of the cleaning component 252. The third motor 266 is equipped with a speed control circuit connected to the PLC controller. The PLC controller can independently adjust the output speed of the third motor 266 and change the polishing rate of the polishing wheel 267. The entire electronic control system relies on various sensors to collect displacement, angle and pressure data in real time, and works with the PLC controller to complete the linkage operation of various structures of the equipment. During use, a vacuum cleaner can be used to assist in dust removal, and water can also be used to assist in cleaning or reduce friction temperature. Specific configuration and installation can be flexibly configured according to needs.
