Technical Field
[0001] This utility model relates to the field of aluminum alloy grinding technology, specifically to a surface grinding device for aluminum alloy ingot production. Background Technology
[0002] Aluminum alloy grinding is an important process in aluminum alloy processing. Its purpose is to remove surface defects and unevenness from aluminum alloy workpieces, improving their flatness, appearance, and surface properties. Grinding aluminum alloy ingots not only removes surface defects such as oxide layers, burrs, pinholes, and cracks, resulting in a smooth surface, but also prevents stress concentration or corrosion problems during subsequent processing or use, significantly improving the corrosion resistance of the aluminum alloy ingots. However, grinding aluminum alloys generates a large amount of debris. Because this debris flies everywhere, a single baffle is insufficient to effectively block it, causing some debris to fall onto critical components such as lead screws, thus affecting the normal operation of the lead screws.
[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number 202321166747.5, application date 2023-05-12) provides a surface grinding device for aluminum alloy ingot production, including a base plate and a base box. The base box is fixedly installed on the base plate. An opening is provided on the upper wall of the base box, and a support platform is slidably installed in the opening. A first motor is fixedly installed on the outer wall of the base box, and the drive end of the first motor passes through the side wall of the base box. When the device is working, the debris generated during the grinding of aluminum alloy ingots can enter the base box and be discharged through the discharge port to prevent debris from accumulating in the base box and affecting the normal rotation of the lead screw. The clamping assembly clamps and fixes the aluminum alloy ingots horizontally and vertically to prevent displacement and movement of the aluminum alloy ingots during grinding, prevents vibration patterns from appearing on the surface of the aluminum alloy ingots during grinding, and improves the yield of aluminum alloy ingot grinding.
[0004] When the grinding force is evenly distributed, the amount of material removed from each part of the aluminum alloy ingot by the grinding wheel can be precisely controlled. Furthermore, the uniform grinding force avoids dimensional deviations caused by excessive or insufficient local grinding force, ensuring product dimensional accuracy and guaranteeing tight fit between components, thereby improving the overall product performance and reliability. However, the aforementioned device cannot ensure sufficient contact between the aluminum alloy ingot and the grinding wheel during use, resulting in uneven distribution of the grinding force generated by the grinding wheel. This leads to differences in the degree of grinding on different parts of the aluminum alloy ingot, causing deviations from the ingot's tolerance range. This affects the fit accuracy with other components, reducing product performance and reliability. Utility Model Content

[0027] 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.
[0028] Example 1: The base 2, frame 1, and fixing block 6 not only improve the stability of the device during operation, but also enhance the precision and quality of grinding aluminum alloy ingots. Figures 1-2 As shown: It includes a frame 1, a base 2 fixedly connected to the upper surface of the frame 1, a grinding component 3 fixedly connected to the upper surface of the base 2, a motor 4 fixedly connected to the upper surface of the frame 1, and a rotating shaft 5 fixedly connected to the output end of the motor 4. A fixing block 6 is fixedly connected to the upper surface of the frame 1 near the motor 4, and the rotating shaft 5 is rotatably installed inside the fixing block 6. A limiting block 7 is fixedly connected to the upper surface of the frame 1 near the base 2, and a sliding rod 8 is fixedly connected to the surface of the limiting block 7. A positioning plate 9 is slidably connected through the sliding rod 8 and is slidably installed on the upper end of the frame 1. A connecting plate 18 is provided on the upper surface of the frame 1 through a reciprocating sliding component, and a sliding shaft 19 is rotatably installed inside the connecting plate 18. A negative pressure lubrication box 25 is fixedly connected to the upper surface of the frame 1 near the motor 4.
[0029] The worker places the aluminum alloy ingot to be processed on the surface of the positioning plate 9, and rotates the threaded rod 12 on the outside of the positioning plate 9, causing the threaded rod 12 to drive the clamping plate 13 to fix the aluminum alloy ingot to be processed, ensuring that the aluminum alloy ingot will not shift during the grinding process, thus providing a guarantee for precise grinding (e.g. Figure 1 and Figure 2 As shown), after the aluminum alloy ingot is installed, the operator starts the motor 4 and the grinding assembly 3. The motor 4 drives the aluminum alloy ingot to slide back and forth at the lower end of the grinding assembly 3, which makes the grinding process more stable and helps to improve the grinding accuracy and grinding quality (as shown). Figure 4 As shown), simultaneously, the lubricant inside the negative pressure lubrication box 25 is sprayed out from the nozzle 21 through the connecting pipe to lubricate and cool the processing area of the device (as shown). Figure 7 As shown in the figure, this not only reduces grinding wheel wear and improves grinding efficiency, but also prevents aluminum alloy ingots from deforming or affecting their material properties due to the high temperature generated during grinding, thus further ensuring grinding quality.
[0030] In Example 2, unlike Example 1, the clamping plate 13, positioning plate 9, and cylinder 14 prevent the aluminum alloy ingot from shifting or shaking due to uneven force during grinding, and effectively resist vibrations and impacts generated during grinding. Figures 3-5 As shown: A baffle 10 is fixedly connected to the outer side of the positioning plate 9, and a limiting rod 11 is fixedly connected to the surface of the baffle 10. A clamping plate 13 is slidably connected to the limiting rod 11. The clamping plate 13 is slidably disposed on the inner wall of the positioning plate 9. The baffles 10 are symmetrically distributed about the center of the positioning plate 9. A threaded rod 12 is rotatably disposed inside the baffle 10. The clamping plate 13 is threadedly connected to the surface of the threaded rod 12. A cylinder 14 is fixedly connected to the surface of the rotating shaft 5. The cylinder 14 is rotatably disposed on the upper end of the frame 1. One end of a connecting rod 15 is slidably connected to the surface of the cylinder 14. At the same time, the other end of the connecting rod 15 is slidably connected to the positioning plate 9.
[0031] When the worker polishes the aluminum alloy ingot, the ingot is placed on the positioning plate 9. A clamping plate 13 is installed on the surface of the rotating threaded rod 12 via a threaded connection. A limiting rod 11 on the surface of the baffle 10 slides through the clamping plate 13. As the worker rotates the threaded rod 12, the threaded transmission causes the clamping plate 13 to slide smoothly along the surface of the limiting rod 11 (e.g., ...). Figure 3As shown), this fixes the aluminum alloy ingot on the inner wall of the positioning plate 9, which not only improves the stability of the device during operation, but also improves the precision and quality of grinding the aluminum alloy ingot. After the aluminum alloy ingot is fixed, the operator starts the motor 4. The motor 4 drives the rotating shaft 5 at the output end to rotate inside the fixing block 6, and causes the cylinder 14 on the surface of the rotating shaft 5 to drive the connecting rod 15 on the surface to slide on the left side. At the same time, the connecting rod 15 drives the positioning plate 9 at the other end to slide back and forth on the surface of the sliding rod 8 (as shown). Figure 4 and Figure 5 As shown, this not only ensures full contact between the aluminum alloy ingot surface and the grinding wheel, but also ensures that the grinding force applied by the grinding wheel to the aluminum alloy ingot surface is uniform and consistent, thus improving the grinding quality of the aluminum alloy ingot.
[0032] In Example 3, unlike Example 2, the support frame 22, sliding frame 23, and connecting frame 20 allow for the uniform spraying of lubricant onto the workpiece's machining area, ensuring sufficient lubrication and cooling for both the grinding wheel and the aluminum alloy ingot. Figures 6-7 As shown: A drive shaft 16 is rotatably mounted inside the base 2, and belts are sleeved and connected to both the surface of the drive shaft 16 and the surface of the rotating shaft 5. A sliding block 17 is fixedly connected to the surface of the drive shaft 16. A support frame 22 is slidably connected to the surface of the sliding shaft 19, and the drive shaft 16 is rotatably mounted inside the support frame 22. A sliding frame 23 is fixedly connected to the surface of the sliding shaft 19. One end of a moving rod 24 is slidably connected to the surface of the sliding frame 23, and the other end of the moving rod 24 is sleeved inside the sliding block 17. The reciprocating sliding assembly includes a connecting frame 20 fixedly connected to the surface of the sliding shaft 19, and a nozzle 21 is fixedly connected to the surface of the connecting frame 20. The nozzle 21 is connected to the inner cavity of the negative pressure lubrication box 25 through a pipe penetrating the outer wall of the connecting frame 20.
[0033] A belt is mounted on the surfaces of the rotating shaft 5 and the drive shaft 16. The belt drive enables the motor 4 to rotate the drive shaft 16 inside the base 2 when the motor 4 is working (e.g., ...). Figure 6 As shown), the rotation of the drive shaft 16 drives the sliding block 17 on the surface to rotate, causing the moving rod 24, which is sleeved inside the sliding block 17, to slide on the surface. Simultaneously, the moving rod 24 slides on the surface of the sliding frame 23 at the other end. With the continuous rotation of the drive shaft 16, the sliding frame 23 is driven to swing (as shown). Figure 7 As shown in the figure, the nozzle 21 on the surface of the connecting frame 20 is connected to the negative pressure lubrication box 25 through the connecting pipe, so that the sliding frame 23 drives the sliding shaft 19 to swing back and forth inside the connecting plate 18, and the sliding shaft 19 drives the connecting frame 20 to swing, which effectively reduces the frictional heat during the grinding process, prevents the aluminum alloy ingot from deforming, burning and other defects due to overheating, and improves the grinding quality.
