[0002] Graphite carbon sleeve grinding equipment is widely used in the manufacturing and processing of batteries, electrodes, seals, and other conductive materials. Graphite and carbon materials are widely used in various industrial fields due to their excellent conductivity, high-temperature resistance, and chemical stability. However, these materials typically require grinding during production to achieve specific dimensional, smoothness, and precision requirements. The main function of graphite carbon sleeve grinding equipment is to remove surface irregularities through fine grinding and surface treatment, ensuring the flatness and precision of the graphite carbon sleeve, and improving its adaptability and functionality in subsequent processes.
[0003] Currently, graphite carbon sleeve grinding equipment on the market mainly relies on manual operation or traditional mechanical fixing methods, which leads to instability during operation. Firstly, traditional equipment is prone to loosening due to improper operation when fixing the graphite carbon sleeve body, thus affecting the uniformity and precision of grinding. Secondly, the existing grinding disc replacement process is complex and time-consuming, usually requiring manual disassembly and multiple steps, impacting production efficiency. Furthermore, traditional equipment often generates a large amount of dust during grinding, and the failure to effectively control dust dispersion not only affects the operating environment but may also pose a threat to worker health.
[0004] Therefore, a graphite carbon sleeve grinding device is proposed to solve the above problems. Utility Model Content

[0033] 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.
[0034] Reference Figure 1 - Figure 5 An embodiment of this utility model provides a graphite carbon sleeve grinding device, including a workbench 7, a water storage tank 6 fixedly connected to the top of the workbench 7, a filter screen 4 installed inside the water storage tank 6, a fixing mechanism set on the top of the water storage tank 6, an installation plate 11 fixedly connected to the outside of the workbench 7, a water spray assembly set on the outside of the installation plate 11, a fixing plate 1 fixedly connected to the outside of the installation plate 11, a hydraulic cylinder 2 installed at the bottom of the fixing plate 1, a fixing column 20 fixedly connected to the output end of the hydraulic cylinder 2, a quick replacement mechanism set inside the fixing column 20, a connecting column 21 slidably connected inside the fixing column 20, and a grinding disc 3 fixedly connected to the bottom of the connecting column 21;
[0035] The fixing mechanism includes a motor 8, which is mounted on top of the water tank 6. The output end of the motor 8 is fixedly connected to a hollow shell 15 via a U-shaped frame. Two clamping plates 17 are slidably connected inside the hollow shell 15, and a push plate 18 is slidably connected between the two clamping plates 17. An electric push rod 16 is installed in the middle of the hollow shell 15, and its output end is fixedly connected to the outside of the push plate 18. A graphite carbon sleeve body 9 is set on the outside of the two clamping plates 17, and a rubber pad 19 is fixedly connected to the outside of the clamping plates 17. The inner wall of the graphite carbon sleeve body 9 abuts against the rubber pad 19. The worktable 7 is the basic platform of the entire equipment, used to support other parts and provide a stable working environment, ensuring that other parts are in a fixed and stable position during the grinding process. The water tank 6 is used to store water or coolant. During the grinding process, water helps to reduce the temperature of the graphite carbon sleeve, reduce grinding debris splashing, improve grinding efficiency, and also clean the working surface and absorb dust. A filter screen 4 is installed inside the water storage tank 6 to filter the sprayed water before it flows back into the tank. This filters impurities to ensure water cleanliness. After prolonged use, the graphite dust on the filter screen 4 needs to be cleaned regularly to prevent clogging and ensure proper water return to the tank. A fixing mechanism securely holds the graphite carbon sleeve body 9 in place, preventing loosening during grinding and ensuring smooth operation. A mounting plate 11 ensures stable installation of all components, guaranteeing good stability during operation. A fixing plate 1 mounts the hydraulic cylinder 2, ensuring stability during operation. The hydraulic cylinder 2 controls the up-and-down movement of the abrasive disc 3, allowing it to contact the graphite carbon sleeve body 9 with appropriate pressure. A fixing column 20 is used to mount the abrasive disc 3, and a connecting column 21 is used to fix the abrasive disc 3, which is then installed inside the fixing column 20. The abrasive disc 3 is used to grind the main components of the graphite carbon sleeve body 9. Through contact with the body, friction smooths the surface or removes unwanted parts. Motor 8 drives the entire fixing mechanism to rotate, thereby causing the graphite carbon sleeve body 9 fixed to the fixing mechanism to rotate. Hollow shell 15 supports its internal parts and provides a mounting location for electric push rod 16, which in turn pushes push plate 18 to move, thereby moving clamping plate 17. Rubber pad 19 contacts the inner wall of graphite carbon sleeve body 9, both to increase friction and prevent detachment, and to prevent clamping plate 17 from damaging graphite carbon sleeve body 9.
[0036] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5The quick-change mechanism includes a housing 14, which is fixedly connected to the outside of a fixing post 20. An inner housing 13 is fixedly connected inside the fixing post 20. A pin 25 is slidably connected inside the inner housing 13. A spring 24 is sleeved on the outside of the pin 25, and a temporary locking assembly is provided on the outside of the pin 25. The pin 25 is inserted into the connecting post 21, and a pull ring is fixedly connected to the end of the pin 25 away from the connecting post 21. The housing 14 carries and protects the internal components, ensuring their proper functioning. The inner housing 13 provides a sliding track for the pin 25, ensuring smooth insertion into the connecting post 21. The pin 25 locks the connecting post 21 to the fixing post 20, thus completing the installation of the abrasive sheet 3. The temporary locking assembly allows for temporary locking after the pin 25 is pulled out, eliminating the need to continuously pull on the pin 25. The pull ring facilitates pulling the pin 25, allowing the connecting post 21 to be removed from the fixing post 20. Spring 24 is used to ensure that pin 25 will not move when no external force is applied.
[0037] Reference Figure 1 - Figure 3 The water spray assembly includes a water pump 12, which is mounted on the outside of a mounting plate 11. A water outlet pipe 10 is fixedly connected to the output end of the mounting plate 11. The end of the water outlet pipe 10 away from the water pump 12 passes through the mounting plate 11 and is located above the abrasive disc 3. The input end of the water pump 12 is fixedly connected to the inside of a water storage tank 6 via a connecting pipe. The water pump 12 is used to draw water from the water storage tank 6 and spray it onto the graphite carbon sleeve body 9 through the water outlet pipe 10. This prevents water from flying away during grinding, facilitates faster grinding, and extends the service life of the abrasive disc 3.
[0038] Reference Figure 4 and Figure 5 The temporary locking assembly includes a pad 22, which is fixedly connected to the outside of the pin 25. A locking block 23 is fixedly connected to the outside of the pad 22. A U-shaped groove 5 is provided on the outside of the inner shell 13. One end of the spring 24 is fixedly connected to one side of the pad 22, and the other end of the spring 24 abuts against the inner wall of the inner shell 13. The pad 22 is slidably connected inside the inner shell 13, and the locking block 23 is slidably connected inside the U-shaped groove 5. The pad 22 is used to fix the locking block 23 and also to transmit the spring force of the spring 24 to the pin 25. The U-shaped slot 5 is used to cooperate with the card block 23. When the pin 25 is pulled out, the card block 23 can be locked inside the U-shaped slot 5 by rotating the pin 25, so that the pin 25 is temporarily locked without having to pull the pin 25 all the time. When it is necessary to unlock, the pin 25 is pulled slightly so that the pin 25 can rotate, and then the pin 25 is rotated in the opposite direction so that the card block 23 can slide inside the U-shaped slot 5. At this time, the pin 25 is unlocked.
[0039] Working principle: When grinding the graphite carbon sleeve body 9, the graphite carbon sleeve body 9 is first placed on the outside of the two clamping plates 17. Next, the electric push rod 16 is activated, which drives the push plate 18 to move, thereby gradually separating the two clamping plates 17 until the rubber pads 19 on the clamping plates 17 contact the inner wall of the graphite carbon sleeve body 9, completing the clamping and fixing of the graphite carbon sleeve body 9. Subsequently, a certain amount of water is added to the water tank 6 to provide a water source for the subsequent grinding process.
[0040] Next, pull the ring to remove the pin 25, and rotate the ring to engage the locking block 23 into the U-shaped slot 5. At this point, the pin 25 is temporarily locked, and there is no need to pull it continuously. Then, insert the connecting post 21 at the top of the suitable frosted sheet 3 into the fixing post 20. Next, slightly pull the ring to allow the pin 25 to rotate, and then rotate the pin 25 in the opposite direction to allow the locking block 23 to slide freely within the U-shaped slot 5. Finally, release the ring, and with the help of the spring 24, the pin 25 will be firmly inserted into the connecting post 21, completing the installation of the frosted sheet 3.
[0041] After installation, hydraulic cylinder 2 is activated, causing the abrasive disc 3 to gradually descend until it contacts the graphite carbon sleeve body 9 with appropriate pressure. Then, motor 8 is started, causing the graphite carbon sleeve body 9 to rotate at a suitable speed, cooperating with the abrasive disc 3 to precisely grind the graphite carbon sleeve body 9. Simultaneously, water pump 12 starts working, drawing water from the water tank 6 and spraying it onto the graphite carbon sleeve body 9 through the water outlet pipe 10. This prevents dust generated during grinding from scattering and effectively extends the service life of the abrasive disc 3. The sprayed water is filtered through filter screen 4 and eventually flows back into the water tank 6. After prolonged use, filter screen 4 needs to be cleaned regularly to prevent accumulated dust from clogging it and affecting water flow and return efficiency.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
