[0013] Preferably, the abutment is configured as a fan-shaped plate, and the abutment abuts against the opening surfaces inside the double-layer limiting plate one and the double-layer limiting plate two.

[0014] By adopting the above technical solution, the abutment plate abuts against the internal opening of the double-layer limiting plate, providing corresponding limiting effects for aluminum coil sleeves of different diameters.

[0015] Preferably, the first double-layer limiting plate and the second double-layer limiting plate have the same structure.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the aluminum coil sleeve outer surface grinding machine:

[0022] 1. In use, this device employs a large stepper motor as the main drive motor, ensuring strong power and stable rotation of the aluminum coil sleeve. The docking design of the connecting shaft and the extension shaft facilitates easy installation and disassembly of the sleeve. Furthermore, the alignment of their centerlines and the flushness of their outer surfaces guarantee stable power transmission and coaxiality, reducing wobbling during rotation and improving grinding accuracy. The extension shaft, designed as a square rod and coupled with a guide rail, provides precise linear motion guidance, ensuring accurate positioning of the sleeve during grinding. The combination of the lifting rod and the support plate allows the device to be adjusted according to the sleeve's size, providing stable support around the extension shaft and adapting to different specifications of aluminum coil sleeves.

[0023] 2. During use, he used double-layer limit plate one and double-layer limit plate two to slide and connect on the guide rail to limit the two ends of the aluminum coil sleeve. At the same time, the structure composed of the lower trapezoidal plate and the upper semi-circular plate of the double-layer limit plate, as well as the silicone ring placed inside, effectively limits the extension shaft and the abutment plate. It can also play a buffering role during the rotation of the sleeve, reducing vibration and wear, and extending the service life of the equipment. Furthermore, the rod at the bottom of the upper semi-circular plate can slide in the lower trapezoidal plate, which works in conjunction with the lifting platform one during lifting and lowering, further enhancing the flexibility and adaptability of the limit.

[0024] 3. The movable slide in the device moves along the guide track through the cooperation of ball screws and auxiliary rods, facilitating the adjustment of the grinding table position so that different parts of the sleeve can be ground. The height of the grinding table can be adjusted through the two-section sliding connection of the lifting platform to meet the grinding needs of sleeves with different diameters. The arc-shaped opening at the upper end of the grinding table, together with the symmetrical electric drive rollers inside and the grinding belt on the surface, allows the grinding belt to better fit the outer surface of the sleeve through the arc shape. The two electric drive rollers are located at both ends of the arc-shaped opening to ensure the tension and stability of the grinding belt, which can efficiently and evenly grind the outer surface of the aluminum coil sleeve.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-6This utility model provides a technical solution: an aluminum coil sleeve outer surface grinding machine, including a main drive motor 1, a lifting platform 1, a guide plate 3, a docking shaft 4, an extension shaft 5, a lifting rod 6, a stop plate 7, a double-layer limiting plate 1 8, a double-layer limiting plate 2 9, a guide rail 10, a ball screw 11, an auxiliary rod 12, a moving slide 13, a lifting platform 2 14, a grinding table 15, and a grinding belt 16;

[0034] Among them, the main drive motor 1 is a large stepper motor. The main drive motor 1 is installed in the upper platform body of the lifting platform 2. The lifting platform 2 is a platform body with a two-stage lifting structure. The main drive motor 1 is the main drive device that drives the aluminum coil sleeve to rotate.

[0035] The output end of the main drive motor 1 is connected to the docking shaft 4, and the docking shaft 4 is docked with the extension shaft 5. A guide plate 3 is provided on one side of the bottom end of the lifting platform 2, and a guide rail 10 is installed inside the guide plate 3. The guide rail 10 is below the extension shaft 5, and the extension shaft 5 is set as a square rod. A strip opening is opened in the upper end of the guide plate 3, and the guide plate 3 and the guide rail 10 are stacked and installed. The surface of the guide rail 10 is provided with 3 slides. The center line of the docking shaft 4 is aligned with the center line of the extension shaft 5, and the curvature of the outer wall of the docking shaft 4 is consistent with the curvature of the outer wall of the abutment plate 7.

[0036] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, when the device is in use, the main drive motor 1 serves as the core power source for rotating the aluminum coil sleeve. After activation, its internal stepper motor assists in the rotation and grinding of the aluminum coil sleeve. Since the main drive motor 1 is installed in the upper part of the lifting platform 2, in actual operation, the position of the main drive motor 1 is adjusted according to the height of the aluminum coil sleeve through the two-stage lifting operation of the lifting platform 2, facilitating docking with sleeves of different heights. During use, the double-layer limiting plate 8 is installed on the guide rail 10 near the docking shaft 4. At this time, the output end of the main drive motor 1 is connected to the docking shaft 4. The connecting shaft 4 is connected to the extension shaft 5, and then the aluminum coil sleeve is installed on the extension shaft 5. The center line of the connecting shaft 4 is aligned with the center line of the extension shaft 5 to ensure coaxiality during power transmission and reduce deviation during rotation. Furthermore, the lifting rod 6 on the surface of the extension shaft 5 pushes the abutment plate 7 close to the inner wall of the aluminum coil sleeve. Since the curvature of the outer wall surface of the connecting shaft 4 is consistent with the curvature of the outer wall surface of the abutment plate 7, it helps to place the sleeve stably on the extension shaft 5 when installing the sleeve. When the lifting rod 6 fully opens the abutment plate 7, the outer wall surface of the connecting shaft 4 is flush with the outer wall surface of the abutment plate 7, avoiding installation instability caused by height difference.

[0037] Lifting rods 6 are provided on all four surfaces of the extension shaft 5, and the lifting rods 6 are equidistantly installed on the surface of the extension shaft 5. The output end of the lifting rod 6 is connected to the abutment plate 7, and the abutment plate 7 surrounds the periphery of the extension shaft 5. The abutment plate 7 is a fan-shaped plate, and the abutment plate 7 abuts against the opening surfaces inside the double-layer limiting plate 1 8 and the double-layer limiting plate 2 9. The extension shaft 5 and the abutment plate 7 pass through the double-layer limiting plate 1 8 and the double-layer limiting plate 2 9, and the double-layer limiting plate 1 8 and the double-layer limiting plate 2 9 are slidably connected at the upper end of the guide rail 10. The double-layer limiting plate 1 8 and the double-layer limiting plate 2 9 have the same structure. The double-layer limiting plate 1 8 is composed of a lower trapezoidal plate and an upper semi-circular plate, and a circular hole is opened between the two plates of the double-layer limiting plate 1 8. Two half silicone rings are placed in the circular hole. The upper semi-circular plate of the double-layer limiting plate 1 8... A rod is provided at the bottom of the plate body, and the rod at the bottom of the upper semi-circular plate of the double-layer limiting plate 18 slides in the lower trapezoidal plate body. The lower layers of the double-layer limiting plate 18 and the double-layer limiting plate 29 are both penetrated by ball screw 11 and auxiliary rod 12. The ball screw 11 is connected to the movable slide table 13. The upper end of the movable slide table 13 is provided with a lifting platform 2 14. A grinding table 15 is installed on the upper end of the lifting platform 2 14. Two electric drive rollers are symmetrically arranged inside the upper end of the grinding platform 15. A grinding belt 16 is sleeved on the surface of the electric drive rollers of the grinding platform 15. The upper end of the grinding platform 15 is set with an arc-shaped opening. The two electric drive rollers of the grinding platform 15 are respectively set at both ends of the arc-shaped opening. The movable slide table 13 is penetrated by ball screw 11 and auxiliary rod 12. The lifting platform 2 14 at the upper end of the movable slide table 13 is a two-section slidingly connected platform body.

[0038] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, the guide rail 10 is installed inside the guide plate 3. The three slides on the surface of the guide rail 10 provide assistance for the movement of the double-layer limiting plate 8 and the double-layer limiting plate 9. The double-layer limiting plate 8 and the double-layer limiting plate 9 further restrict the aluminum coil sleeve at both ends, so that the whole can accurately position the extension shaft 5 in the horizontal direction, restrict its movement trajectory, and ensure the stability of the aluminum coil sleeve during the grinding process. Since the bottom of the upper semi-circular plate of the double-layer limiting plate 8 and the double-layer limiting plate 9 is provided with a rod, and the rod slides in the lower trapezoidal plate, when the lifting platform 2 is raised, the double-layer structure of the double-layer limiting plate 8 and the double-layer limiting plate 9 has a certain connection point, thereby restricting the sleeve. When the sleeve vibrates during rotation, the silicone ring in the circular hole can further absorb the vibration, reduce the impact of vibration on the grinding accuracy and equipment parts, and extend the service life of the equipment.

[0039] When installing aluminum coil sleeves of different diameters, the extension length of the lifting rod 6 can be adjusted to make the abutment plate 7 in close contact with the inner wall of the sleeve. Since the abutment plate 7 is set as a fan-shaped plate body, surrounding the extension shaft 5, it is convenient to abut against the inner wall surface of the aluminum coil sleeve during use, and further abut against the opening surface inside the double-layer limiting plate 8 and the double-layer limiting plate 9, thereby providing stable support for the sleeve. The abutment plate 7 can also be flexibly adjusted according to the size of the sleeve to adapt to different specifications of sleeves.

[0040] When grinding the surface of an aluminum coil sleeve, the rotation of the ball screw 11 is controlled by a motor, which drives the movable slide 13 to move along the guide rail 10. The position of the grinding table 15 in the horizontal direction is adjusted so that the grinding table 15 can be aligned with the part of the aluminum coil sleeve that needs to be ground. At the same time, the lifting platform 14 at the upper end of the movable slide 13 is a two-section sliding platform body. The height of the grinding table 15 can be further adjusted according to the diameter of the sleeve, so that the grinding belt 16 maintains a suitable contact position with the outer surface of the sleeve. When the electric drive roller of the grinding table 15 is energized, it drives the grinding belt 16 to rotate cyclically. Due to the arc-shaped opening of the grinding table 15, the grinding belt 16 fits better with the outer surface of the aluminum coil sleeve, and performs comprehensive and uniform grinding on the outer surface of the sleeve. The grinding belt 16 of different thicknesses can be replaced according to the actual use to achieve the grinding treatment.

[0041] Working Principle: When using this aluminum coil sleeve outer surface grinding machine, the two-stage lifting structure of the lifting platform 12 is used to adjust and match the height of the aluminum coil sleeve so that the height is aligned with the main drive motor 1. The aluminum coil sleeve is then installed on the extension shaft 5. During use, the docking shaft 4 at the output end of the main drive motor 1 is precisely docked with the extension shaft 5. Then, the double-layer limiting plate 1 8 and double-layer limiting plate 2 9 slide with the guide rail 10 in the guide plate 3 to achieve installation on both sides of the aluminum coil sleeve. At this time, the lifting rod 6 adjusts the outward expansion length of the abutment plate 7 according to the sleeve diameter, so that the abutment plate 7 fits tightly against the inner wall of the sleeve, providing stable support for the sleeve and adapting to sleeves of different specifications. Then, the main drive motor 1 is turned on to rotate, and the symmetrically set upper end of the grinding table 15 is activated. Two electrically driven rollers drive the polishing belt 16 to rotate cyclically. Due to the arc-shaped opening design at the upper end of the polishing table 15, the polishing belt 16 can closely fit the outer surface of the aluminum coil sleeve, performing comprehensive and uniform polishing. The main drive motor 1 drives the sleeve to rotate, cooperating with the polishing belt 16 to complete the polishing work. Furthermore, by controlling the rotation of the ball screw 11, the moving slide 13 is driven to move along the guide rail 10, thereby adjusting the horizontal position of the polishing table 15 and aligning it with the part of the aluminum coil sleeve to be polished. After polishing is completed, the electrically driven rollers and the main drive motor 1 are turned off in sequence, and then the lifting platform 12 and the lifting platform 2 14 are lowered to remove the polished aluminum coil sleeve and clean the polishing debris from the surface of the equipment, preparing for the next operation and increasing the overall practicality.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
