Description

Technical Field

[0001] This invention belongs to the field of aluminum tube processing technology, specifically a smart pressure-controlled automated grinding machine for the inner wall of aluminum tubes. Background Technology

[0002] Aluminum tubes are hollow metal tubular materials made from pure aluminum or aluminum alloys through extrusion processing, belonging to the category of non-ferrous metal tubes. They possess advantages such as light weight, corrosion resistance, and ease of processing, and are widely used in industries such as automobiles, ships, aerospace, aviation, electrical appliances, electromechanical products, and home furnishings. After extrusion molding, the inner wall of aluminum tubes may have defects such as burrs, unevenness, grooves, and fish-scale patterns. If these defects are not addressed, they will affect the performance of the pipe; therefore, the inner wall of the aluminum tube needs to be polished to remove these defects.

[0003] Patent CN221270544U discloses a device for grinding the inner wall of an aluminum tube used in shock absorbers. The device includes a processing box with a cleaning groove on the front and an open top. An aluminum tube is placed inside the processing box. An inner wall grinding mechanism is located at the lower end of the inner cavity, and an aluminum tube conveying mechanism for vertical feeding is located above the grinding mechanism. The grinding mechanism includes a rotating shaft movably mounted inside the processing box, and a drive motor for driving the rotating shaft is fixedly installed at the lower end of the processing box. This patent, by setting up an inner wall grinding mechanism and utilizing the interaction between grinding protrusions and a grinding disc, can automatically and quickly grind the inner wall of the aluminum tube, greatly improving the efficiency of inner wall grinding. Furthermore, the debris generated during grinding falls into a debris storage tray for easy cleaning.

[0004] However, the above technical solutions still have the following shortcomings in practical applications: When polishing the inner wall of an aluminum tube, a polishing wheel needs to be inserted into the tube. However, as the polishing wheel moves according to a set coordinate system, when the aluminum tube is elliptical or bent, the wheel may fail to contact the inner wall or forcefully compress it, affecting the polishing effect and potentially damaging the tube. Furthermore, the flying debris generated during polishing can easily spill out of the tube opening, polluting the surrounding environment. After polishing, some debris remains on the inner wall of the tube. When the tube is used to transport fluids or as a moving part, this debris can scratch the inner wall and wear down seals as the medium moves or the parts move, ultimately shortening the lifespan of the entire system.

[0016] The beneficial effects of this invention are as follows: 1. The present invention discloses an intelligent pressure-controlled automated grinding machine for the inner wall of aluminum tubes. Utilizing an intelligent pressure-controlled grinding component, during the grinding process, a pressure sensor can monitor the pressure between the grinding wheel and the inner wall of the aluminum tube in real time, and adjust the position of the grinding wheel in real time according to the pressure magnitude to ensure that the grinding pressure remains consistent.

[0017] 2. The intelligent pressure-controlled automatic aluminum tube inner wall grinding machine of the present invention, during the grinding process, baffle one and baffle two cover the openings on both sides of the aluminum tube, so that the grinding wheel is in a closed environment, so that the debris will only concentrate in the inner cavity of the aluminum tube and will not splash out through the openings on both sides of the aluminum tube, thereby avoiding debris pollution of the surrounding environment.

[0018] 3. The intelligent pressure-controlled automatic grinding machine for the inner wall of aluminum tubes described in this invention utilizes a debris cleaning auxiliary component to remove and collect debris remaining on the inner wall of the aluminum tube. This avoids the situation where debris remains on the inner wall of the aluminum tube, moves with the medium, scratches the inner wall of the aluminum tube, and wears the seals, thereby helping to extend the service life of the entire pipeline system.

[0019] 4. The intelligent pressure-controlled automatic grinding machine for the inner wall of aluminum tubes described in this invention, whenever the circular pad moves from one end of the aluminum tube to the other, the surface of the circular pad adheres to the edge of the scraper, which drives the scraper to rotate. The scraper scrapes off the debris adhering to the surface of the circular pad, thereby achieving self-cleaning of the surface of the circular pad. This prevents the debris adhering to the surface of the circular pad from falling back onto the inner wall of the aluminum tube when the circular pad is reset, further avoiding the situation where debris remains on the inner wall of the aluminum tube.

The circular pad 14 is made of elastic material.

[0025] In this embodiment, as Figure 1 , Figure 2 , Figures 5-12 As shown, a motor 17 is fixedly connected to one side of the upper end of the support column 12, and the output end of the motor 17 is fixedly connected to the middle of the rotating rod 13.

Motor 3 25 is fixedly connected to one side of support block 24. The output end of motor 3 25 is fixedly connected to one end of grinding wheel 15.

[0027] A baffle 4 is slidably connected to one side of the upper end of the grinding table 1, and a cylinder 6 is fixedly connected to one side of the upper end of the grinding table 1. The piston end of the cylinder 6 is fixedly connected to one end of the slide plate 27, and a collection box 5 is provided on one side of the upper end of the grinding table 1.

[0028] Multiple tension rods 33 are evenly distributed and slidably connected along the circumference of the fixed plate 32. One end of each tension rod 33 is fixedly connected to a positioning pin 35, which is fixedly inserted through the edge of the circular pad 14.

[0029] One end of the tension rod 33 is threadedly connected to a threaded rod 11, and both ends of the threaded rod 11 are rotatably mounted on the fixed plate 32.

[0030] One end of the threaded rod 11 is fixedly fitted with a bevel gear 29, and a bevel gear 23 is rotatably mounted on one side of the fixed disk 32. The bevel gear 23 meshes with multiple bevel gears 29.

[0031] A motor 34 is fixedly connected to one side of the fixed plate 32, and the output end of the motor 34 is fixedly connected to the bevel gear 23.

[0032] A rodless cylinder 16 is fixedly installed on one side of the rotating rod 13. A baffle 3 is fixedly connected to the slider of the rodless cylinder 16, and the baffle 3 is slidably sleeved on the rotating rod 13.

[0033] Specifically, in existing technology, when grinding the inner wall of an aluminum tube, a grinding wheel 15 needs to be inserted into the tube. However, as the grinding wheel 15 moves according to a set coordinate, when the aluminum tube is elliptical or bent, the grinding wheel 15 may fail to contact the inner wall or forcefully compress it, affecting the grinding effect and potentially damaging the tube. Furthermore, the flying debris generated during grinding can easily spill out of the tube opening, polluting the surrounding environment. Moreover, after grinding, some debris remains on the inner wall of the tube. When the tube is used to transport fluids or as a moving part, this debris can scratch the inner wall and wear down seals as the medium moves or the parts move, ultimately shortening the lifespan of the entire system.

[0034] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: First, place the aluminum tube to be polished between two positioning blocks 9. Then, simultaneously activate two cylinders 6 to bring the two positioning blocks 9 closer together and clamp the aluminum tube. At this point, the aluminum tube, the output end of motor 19, baffle 3, and circular pad 14 are coaxial. Cylinder 6 drives baffle 4 to move laterally, so that baffle 4 is in contact with the right end face of the aluminum tube. Linear motor module 7 drives slide 10 to move laterally, so that rotating rod 13 extends into the aluminum tube. Subsequently, cylinder 21 drives connecting block 22 to move, so that grinding wheel 15 fits against the inner wall of aluminum tube. Furthermore, rodless cylinder 16 drives slider and baffle 3 to move laterally. So no matter where grinding wheel 15 is on the inner wall of aluminum tube, baffle 3 will fit against the left end face of aluminum tube. Then, motor 25 drives grinding wheel 15 to rotate, and motor 19 drives rotating block 20, so that grinding wheel 15 can grind around the inner wall of aluminum tube. Since grinding wheel 15 is in a closed environment, the debris will only concentrate in the inner cavity of aluminum tube and will not splash out through the openings on both sides of aluminum tube, thus avoiding debris pollution of the surrounding environment. Furthermore, during the polishing process, the pressure sensor 26 can monitor the pressure between the polishing wheel 15 and the inner wall of the aluminum tube in real time, and adjust the position of the polishing wheel 15 in real time according to the pressure to ensure that the polishing pressure remains constant. This avoids situations where the polishing wheel 15 cannot contact the inner wall of the aluminum tube or is forcibly squeezed due to the ellipticity or bending of the aluminum tube, thus ensuring the polishing effect and preventing the aluminum tube from being damaged by compression.

[0035] After the grinding work is completed, the grinding wheel 15 is removed from the inner cavity of the aluminum tube. Then, the motor 17 drives the rotating rod 13 to rotate 180 degrees, so that the circular pad 14 faces the aluminum tube. Then, according to the diameter of the aluminum tube, the motor 5 34 drives the bevel gear 23 to rotate, so that multiple bevel gears 29 and multiple threaded rods 11 can rotate at the same time, so that multiple tension rods 33 slide radially on the fixed plate 32 at the same time. The positioning pins 35 at the ends of the tension rods 33 stretch the edge of the circular pad 14, so that the edge of the circular pad 14 is aligned with the edge of the inner wall of the aluminum tube. Then, the circular pad 14 is driven to extend into the inner wall of the aluminum tube, so that the debris attached to the inner wall of the aluminum tube can be scraped off through the edge of the circular pad 14. At this point, if the baffle 4 is driven away from the right end of the aluminum tube, the impurities scraped by the circular pad 14 will fall into the collection box 5 through the opening of the aluminum tube. This achieves the removal and collection of debris remaining on the inner wall of the aluminum tube, avoiding the situation where debris remains on the inner wall of the aluminum tube, moves with the medium, scratches the inner wall of the aluminum tube, and wears the seals. This helps to extend the service life of the entire pipeline system.

[0036] In this embodiment, as Figure 2 and Figure 3 As shown, a scraper 30 is rotatably mounted on one side of the baffle 2 4, and a motor 4 28 is fixedly connected to one side of the baffle 2 4. The output end of the motor 4 28 is fixedly connected to the middle of the scraper 30.

[0037] Specifically, in the above embodiments, although the circular pad 14 can be used to scrape away the debris remaining on the inner wall of the aluminum tube, the debris will inevitably stick to the surface of the circular pad 14 because the circular pad 14 is elastic. When the circular pad 14 completes a scraping action and resets, the edge of the circular pad 14 will contact the inner wall of the aluminum tube again, and the circular pad 14 will vibrate. The debris stuck to the surface of the circular pad 14 is easy to fall back to the inner wall of the aluminum tube, still causing debris residue.

[0038] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: Whenever the circular pad 14 moves from one end of the aluminum tube to the other, the surface of the circular pad 14 comes into contact with the edge of the scraper 30. The scraper 30 can then be rotated by the motor 28 to scrape off the debris adhering to the surface of the circular pad 14. This causes the debris to fall off the surface of the circular pad 14, thus achieving self-cleaning of the surface of the circular pad 14. This prevents the debris adhering to the surface of the circular pad 14 from falling back onto the inner wall of the aluminum tube when the circular pad 14 is reset, further preventing debris from remaining on the inner wall of the aluminum tube.

[0039] Working principle: First, the aluminum tube to be polished is placed between two positioning blocks 9. Then, two cylinders 6 are activated simultaneously to bring the two positioning blocks 9 closer together and clamp the aluminum tube. At this time, the aluminum tube, the output end of motor 19, baffle 3, and circular pad 14 are coaxial. Cylinder 6 drives baffle 4 to move laterally, so that baffle 4 is in contact with the right end face of the aluminum tube. Linear motor module 7 drives slide 10 to move laterally, so that rotating rod 13 extends into the aluminum tube. Subsequently, cylinder 21 drives connecting block 22 to move, so that grinding wheel 15 fits against the inner wall of aluminum tube. Furthermore, rodless cylinder 16 drives slider and baffle 3 to move laterally. So no matter where grinding wheel 15 is on the inner wall of aluminum tube, baffle 3 will fit against the left end face of aluminum tube. Then, motor 25 drives grinding wheel 15 to rotate, and motor 19 drives rotating block 20, so that grinding wheel 15 can grind around the inner wall of aluminum tube. Since grinding wheel 15 is in a closed environment, the debris will only concentrate in the inner cavity of aluminum tube and will not splash out through the openings on both sides of aluminum tube, thus avoiding debris pollution of the surrounding environment. Furthermore, during the polishing process, the pressure sensor 26 can monitor the pressure between the polishing wheel 15 and the inner wall of the aluminum tube in real time, and adjust the position of the polishing wheel 15 in real time according to the pressure to ensure that the polishing pressure remains constant. This avoids situations where the polishing wheel 15 cannot contact the inner wall of the aluminum tube or is forcibly squeezed due to the ellipticity or bending of the aluminum tube, thus ensuring the polishing effect and preventing the aluminum tube from being damaged by compression.

[0040] After the grinding work is completed, the grinding wheel 15 is removed from the inner cavity of the aluminum tube. Then, the motor 17 drives the rotating rod 13 to rotate 180 degrees, so that the circular pad 14 faces the aluminum tube. Then, according to the diameter of the aluminum tube, the motor 5 34 drives the bevel gear 23 to rotate, so that multiple bevel gears 29 and multiple threaded rods 11 can rotate at the same time, so that multiple tension rods 33 slide radially on the fixed plate 32 at the same time. The positioning pins 35 at the ends of the tension rods 33 stretch the edge of the circular pad 14, so that the edge of the circular pad 14 is aligned with the edge of the inner wall of the aluminum tube. Then, the circular pad 14 is driven to extend into the inner wall of the aluminum tube, so that the debris attached to the inner wall of the aluminum tube can be scraped off through the edge of the circular pad 14. At this point, if the baffle 4 is driven away from the right end of the aluminum tube, the impurities scraped by the circular pad 14 will fall into the collection box 5 through the opening of the aluminum tube. This achieves the removal and collection of debris remaining on the inner wall of the aluminum tube, avoiding the situation where debris remains on the inner wall of the aluminum tube, moves with the medium, scratches the inner wall of the aluminum tube, and wears the seals. This helps to extend the service life of the entire pipeline system.

[0041] Whenever the circular pad 14 moves from one end of the aluminum tube to the other, the surface of the circular pad 14 comes into contact with the edge of the scraper 30. The scraper 30 can then be rotated by the motor 28 to scrape off the debris adhering to the surface of the circular pad 14. This causes the debris to fall off the surface of the circular pad 14, thus achieving self-cleaning of the surface of the circular pad 14. This prevents the debris adhering to the surface of the circular pad 14 from falling back onto the inner wall of the aluminum tube when the circular pad 14 is reset, further preventing debris from remaining on the inner wall of the aluminum tube.
