[0014] This invention provides a processing device for intelligent manufacturing of ultra-micro-shaped cylinder liners. It has the following beneficial effects: (1) This invention allows for quick replacement of grinding wheels by installing a grinding wheel at each end of the double-headed telescopic rod. The replaced grinding wheel is dressed during the operation of the new grinding wheel, which can quickly return to a working state, saving the time of handling and installation when changing grinding wheels and improving work efficiency.

[0015] (2) This invention, by setting up an arc frame, stores the grinding fluid that would otherwise only briefly contact the workpiece and be lost in the arc frame. Through the complete contact between the grinding fluid surface and the bottom of the workpiece, the grinding area of ​​the workpiece surface is cooled for a long time and comprehensively. It can also bring metal debris from the workpiece surface into the arc frame to clean the workpiece surface and prevent the area with debris on the workpiece surface from affecting the grinding effect when it returns to the grinding area. The rotating plate will periodically scoop up the debris inside the arc frame to ensure the size of the effective space inside the arc frame. It can collect as much grinding fluid as possible in the limited space of the arc frame to improve the cooling effect on the workpiece surface. At the same time, the rotating plate will vibrate the grinding fluid each time it approaches the grinding area, causing the grinding fluid to splash onto the grinding area to directly cool the contact surface between the grinding wheel and the workpiece, avoiding the temperature from getting too high and causing a fire.

[0016] (3) In this invention, a filter plate and a baffle are set at the bottom of the arc frame. The opening and closing of the baffle controls the retention and discharge of the grinding fluid inside the arc frame. The filter plate is opened intermittently by the reciprocating movement of the baffle, so that the grinding fluid that has absorbed heat inside the arc frame flows out slowly, thereby improving the cooling utilization rate of the grinding fluid and reducing waste. At the same time, the filter plate can filter the grinding fluid that finally flows to the surface of the worktable, preventing the grinding fluid from being carried to the surface of the worktable and ensuring the cleanliness of the working environment.

[0019] 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.

[0020] Please see Figures 1-17 One embodiment of the present invention is: a processing device for intelligent manufacturing of micro-shaped cylinder liners, comprising a worktable 1 and a slide rail 2. The slide rail 2 is fixedly installed at both ends of the worktable 1. A clamp 3 and an electrical box 4 are slidably installed on the surfaces of the front and rear slide rails 2, respectively. A motor 5 is provided on the surface of the electrical box 4. A double-headed telescopic rod 6 is sleeved on the surface of the electrical box 4. A cover 7 is rotatably installed on the surface of the electrical box 4. A nozzle 8 is provided on the surface of the electrical box 4. A chuck 10 is fixedly installed at the output end of the motor 5. A clamp 11 is provided at the free end of the double-headed telescopic rod 6. A grinding wheel 9 is installed between the chuck 10 and the clamp 11. Rotating the double-headed telescopic rod 6 can replace the grinding wheels 9 at both ends. The replaced grinding wheel 9 moves to the dressing area for dressing. The two grinding wheels 9 can work alternately. The electrical box 4 is rotatably installed on the surface of the motor 5. There is a transmission wheel 18, and a transmission belt 12 is sleeved on the surface of the transmission wheel 18 and the output end of the motor 5. The transmission belt 12 transmits the power from the output end of the motor 5 to the transmission wheel 18, causing the transmission wheel 18 to rotate. A fixed frame 17 is fixedly installed on the surface of the electrical box 4. A rotating ring 19 is rotatably installed on the surface of the fixed frame 17. The rotating ring 19 meshes with the surface of the transmission wheel 18. When the transmission wheel 18 rotates, it pushes the rotating ring 19 to rotate. A first elastic telescopic rod 21 is fixedly installed on the surface of the rotating ring 19. A grinding wheel 20 is rotatably installed on the surface of the first elastic telescopic rod 21. The grinding wheel 20 will move under the elastic force of the first elastic telescopic rod 21 and can always keep in contact with the surface of the grinding wheel 9. The surface of the grinding wheel 20 meshes with the surface of the fixed frame 17. When the grinding wheel 20 rotates along the surface of the fixed frame 17, it will rotate on its own axis.

[0021] The grinding wheel 9 has a groove near the clamp 11. The inner wall of the clamp 11 has a boss 13, which is located in the groove and fits against the inner wall of the groove. The boss 13 serves to fix the grinding wheel 9 in the clamp 11. A clamping plate 14 is slidably installed on the surface of the boss 13. When the clamping plate 14 applies a pushing force to the groove, it can resist the grinding wheel 9. A push rod 16 is fixedly installed on the surface of the clamping plate 14. The push rod 16 extends through the surface of the boss 13 and into the inside of the boss 13. A vertical block 15 is slidably installed inside the boss 13. A first spring is provided between the vertical block 15 and the clamp 11. The elastic force of the first spring causes the vertical block 15 to return to its original position. The bottom of the vertical block 15 is set as an inclined surface. The position of the inclined surface at the bottom of the vertical block 15 controls the advance of the push rod 16. The top of the vertical block 15 passes through the surface of the clamp 11. The vertical block 15 is limited by the closing of the cover 7.

[0022] In this embodiment, the machining of cylinder liners requires grinding the outer diameter of the workpiece material first. During the grinding process, the surface of the grinding device will be worn. It needs to be replaced frequently during long-term machining. The replaced grinding device needs to be repaired before it can be used in subsequent machining processes, resulting in low work efficiency.

[0023] By setting up a double-headed telescopic rod 6, a grinding wheel 9 is installed on each of the free ends of the double-headed telescopic rod 6. The old and new grinding wheels 9 can be replaced simply by rotating the double-headed telescopic rod 6. Moreover, the replaced grinding wheel 9 can be automatically dressed during subsequent processing.

[0024] After processing for a period of time, the surface of the grinding wheel 9 at the front end of the double-headed telescopic rod 6 becomes worn, making it impossible to continue precisely grinding the workpiece. At this point, rotate the cover 7 to open it, pull the double-headed telescopic rod 6 to separate the old grinding wheel 9 from the chuck 10, rotate the double-headed telescopic rod 6 to align the mating position of the new grinding wheel 9 at the other end with the chuck 10, and then push the double-headed telescopic rod 6 to complete the mating of the new grinding wheel 9 with the chuck 10, thus completing the connection between the new grinding wheel 9 and the output end of the motor 5. Then close the cover 7, and after the motor 5 restarts, it will drive the new grinding wheel 9 to rotate and continue grinding the workpiece. During grinding, the old grinding wheel 9, which is being replaced, is rotated to a dressing area away from the grinding area, and its surface is in contact with the grinding wheel 20. At this time, the output end of the motor 5 rotates, driving the transmission belt 12 to move. The transmission belt 12 drives the drive wheel 18 to rotate, and the drive wheel 18 drives the rotating ring 19 to rotate. When the rotating ring 19 rotates, it drives the grinding wheel 20 to rotate on the surface of the old grinding wheel 9. At the same time, because the grinding wheel 20 is engaged with the surface of the fixed frame 17, the grinding wheel 20 will rotate on its own axis under the limit of the fixed frame 17 while following the revolution of the rotating ring 19, thus dressing the surface of the old grinding wheel 9. Moreover, the grinding wheel 20 will adjust its own position according to the wear degree of the surface of the old grinding wheel 9. The elasticity of the first elastic telescopic rod 21 allows the grinding wheel 20 to always be in contact with the surface of the old grinding wheel 9, adapting to various degrees of wear on the surface of the old grinding wheel 9.

[0025] Meanwhile, when the old grinding wheel 9 is replaced, the cover 7 releases its restriction on the vertical block 15. The vertical block 15 is lifted up by the elastic force of the first spring, which drives the bottom inclined surface to press the abutment rod 16, pushing the abutment rod 16 to move. The abutment rod 16 drives the clamping plate 14 to move and stick to the inner wall of the groove of the old grinding wheel 9 to block the old grinding wheel 9, preventing the old grinding wheel 9 from shaking and ensuring that there is friction between the surface of the old grinding wheel 9 and the grinding wheel 20 during the dressing process, thus ensuring the dressing effect.

[0026] Please see Figures 1-17Based on the above embodiments, in another embodiment of the present invention, an arc frame 22 is fixedly installed on the surface of the electrical box 4. The arc frame 22 has slots 28 at its front and rear. The grinding fluid contained in the arc frame 22 can always be in contact with the bottom of the workpiece. A slider 26 is slidably installed on the inner wall of the arc frame 22. A second spring is provided between the slider 26 and the arc frame 22. The elastic force of the second spring causes the slider 26 to return to its original position. A rotating plate 30 is rotatably installed on the surface of the slider 26. The slider 26 drives the rotating plate 30 to slide. The rotating plate 30 and the slider 26 are connected... A first torsion spring is provided, and the elastic force of the first torsion spring causes the rotating plate 30 to return to its original position. A connecting rod 24 is slidably mounted on the surface of the electrical box 4. A push rod 38 is fixedly mounted on the surface of the rotating ring 19. When the rotating ring 19 rotates, it drives the push rod 38 to move, and the push rod 38 pushes the connecting rod 24 to move. A telescopic rod 25 is provided next to the slider 26. The free end of the telescopic rod 25 is fixedly connected to the slider 26, and the fixed end is fixedly connected to the connecting rod 24. The telescopic rod 25 converts the transverse linear motion of the connecting rod 24 into the transverse curved motion of the slider 26 on the inner wall of the arc frame 22.

[0027] A second elastic telescopic rod 35 is rotatably installed inside the arc frame 22. A second torsion spring is provided between the second elastic telescopic rod 35 and the arc frame 22. The elastic force of the second torsion spring causes the second elastic telescopic rod 35 to return to its original position. A ball head 36 is fixedly installed at the free end. The ball head 36 blocks the rotating plate 30, causing the rotating plate 30 and the slider 26 to press against each other. A limit plate 37 is fixedly installed above the ball head 36, which limits the second elastic telescopic rod 35 to rotate only in one direction.

[0028] In this embodiment, during the processing, the nozzle 8 sprays grinding fluid onto the grinding area to cool the grinding wheel 9 and the workpiece surface, while also preventing debris from splashing. However, after the grinding fluid is sprayed out, it falls quickly under its own gravity and splashes onto the surface of the worktable 1. The utilization rate of the grinding fluid is low, and it cannot fully contact the bottom of the workpiece as it flows down, resulting in poor cooling effect. It also carries debris to the surface of the worktable 1, polluting the working environment.

[0029] The grinding fluid sprayed from nozzle 8 flows through the contact area between the grinding wheel 9 and the workpiece before falling into the arc frame 22 for temporary storage. The grinding fluid in the arc frame 22 is in complete contact with the bottom area of ​​the workpiece surface, continuously absorbing heat from the workpiece surface for cooling. Simultaneously, when the rotating ring 19 rotates, it drives the push rod 38 to rotate. The push rod 38 continuously pushes the connecting rod 24 to move, which in turn drives the telescopic rod 25 to move. The telescopic rod 25 pushes the slider 26 to slide along the inner wall of the arc frame 22. After sliding, the arc frame 22 returns to its original position under the force of the second spring, achieving a reciprocating motion. The reciprocating sliding of the slider 26 along the inner wall of the arc frame 22 causes the rotating plate 30 to move back and forth along the arc frame 22, thus actuating the arc frame 22. The internal grinding fluid increases the fluidity and improves the cooling effect on the workpiece surface. Simultaneously, whenever the rotating plate 30 approaches the grinding area during movement, it is limited and squeezed by the ball head 36, causing it to rotate. The second elastic telescopic rod 35 provides pressure to the ball head 36 to compress the rotating plate 30. The rotating plate 30 compresses the first torsion spring, causing it to deform and accumulate elastic force. When the rotating plate 30 rotates to its maximum limit, it pushes away the ball head 36, releasing the ball head 36 from its limiting position. At this moment, the accumulated elastic force of the first torsion spring is released instantly, causing the rotating plate 30 to quickly bounce towards the grinding area and vibrate the grinding fluid on the surface of the arc frame 22, causing the grinding fluid to splash onto the grinding area and directly cool it.

[0030] Please see Figures 1-17 Based on the above embodiments, in another embodiment of the present invention, baffles 23 are provided on both sides of the arc frame 22. The baffles 23 have a blocking effect on the debris generated during grinding, preventing debris from splashing. A swing head 33 is rotatably installed at the bottom of the rotating plate 30. A third torsion spring is provided between the swing head 33 and the rotating plate 30. The third torsion spring provides elastic force for the swing head 33 to pop out. The swing head 33 and the rotating plate 30 are bent at a certain angle. When limited by the bottom of the arc frame 22, there is a moving angle between the swing head 33 and the rotating plate 30. A protrusion 32 is fixedly installed on the surface of the rotating plate 30. A limit hook 27 is fixedly installed on the surface of the arc frame 22 near the protrusion 32. During the reset process of the slider 26, the limit hook 27 blocks the protrusion 32, causing the rotating plate 30 to be squeezed and lifted. A step 29 is provided at the front slot 28. When the swing head 33 is flush with the step 29, the limit is released and it pops out.

[0031] A scraper 39 is slidably mounted on the surface of the rotating plate 30. The scraper 39 is provided with a pull rod 34. One end of the pull rod 34 is hinged to the surface of the scraper 39, and the other end is hinged to the surface of the swing head 33. The scraper 39 is driven to slide by the swing head 33 popping out.

[0032] In this embodiment, when the slider 26 resets, it drives the rotating plate 30 to reset as well. The rotating plate 30 drives the swing head 33 to scrape the bottom of the arc frame 22, causing the chips that enter the bottom of the arc frame 22 along with the grinding fluid to move together. Before the slider 26 is fully reset, the protrusion 32 on the surface of the rotating plate 30 will contact the limiting hook 27 and be limited, causing the rotating plate 30 to rotate upward. The rotating plate 30 drives the swing head 33 to move into the step 29. At the moment the swing head 33 moves into the step 29, the swing head 33 rotates and unfolds under the elastic force of the third torsion spring. After rotation, it bounces the chips it carries into the front slot 28 for accumulation, separating the chips from the main area of ​​the arc frame 22. This ensures that there is enough space in the arc frame 22 to hold as much grinding fluid as possible, ensuring the cooling effect on the workpiece. At the same time, when the swing head 33 swings, it pulls the scraper 39 to move through the pull rod 34, pushing the chips into the slot 28, ensuring that the chips enter the slot 28 smoothly.

[0033] Please see Figures 1-17 Based on the above embodiments, in another embodiment of the present invention, a filter plate 31 is provided at the bottom of the arc frame 22, and a baffle 40 is slidably installed below the filter plate 31. When the baffle 40 slides to be misaligned with the filter plate 31, a portion of the grinding fluid is filtered and discharged through the filter plate 31. An arc block 41 is fixedly installed on the surface of the baffle 40. The baffle 40 is moved and squeezed by the telescopic rod 25 to drive the arc block 41 to move back and forth.

[0034] The baffle 40 has the same width as the filter plate 31, and the surface of the baffle 40 is in contact with the bottom of the filter plate 31. When the baffle 40 is aligned with the filter plate 31, the grinding fluid in the arc frame 22 is retained.

[0035] In this embodiment, the bottom of the arc frame 22 is set as a filter plate 31. When the connecting rod 24 drives the telescopic rod 25 to move, the telescopic rod 25 will frequently squeeze and push the arc block 41, causing the baffle 40 to move back and forth at the bottom of the filter plate 31. When the baffle 40 and the filter plate 31 are misaligned, part of the grinding fluid in the arc frame 22 flows out through the filter plate 31, and at the same time, new grinding fluid enters the arc frame 22 to replenish the remaining amount, so that the grinding fluid in the arc frame 22 can be replaced intermittently. The grinding fluid that absorbs heat is discharged, and new grinding fluid enters at the same time, which improves the utilization rate of the grinding fluid and improves the cooling effect on the workpiece. At the same time, the filter plate 31 will also keep the grinding fluid that finally flows to the surface of the worktable 1 clean and free of debris, protecting the working environment of the worktable 1 surface.
