[0002] With the development of industrial manufacturing technology, aluminum alloys, due to their lightweight and high strength, are widely used in aerospace, automotive manufacturing, and electronic products. Polishing of aluminum alloy parts is a crucial step in improving their surface quality and aesthetics, directly impacting the product's market competitiveness.

[0003] A search revealed that patent CN222570350U discloses a polishing device for aluminum alloy castings. This patent uses a three-grip chuck to clamp one end of the aluminum alloy cylinder to be polished. A corresponding controller controls an electro-hydraulic push rod to move a slider to the right, thereby moving the clamped aluminum alloy cylinder to the right, allowing the positioning post and polishing plate to be inserted into the aluminum alloy cylinder for polishing. However, this device uses a single-piece fixing and single-piece polishing method, which can only polish one aluminum alloy part at a time, resulting in extremely low processing efficiency and making it difficult to meet the needs of large-scale industrial production. Utility Model Content

[0004] Based on the aforementioned technical problems of low processing efficiency caused by the use of single-piece fixing and single-piece grinding methods in traditional devices, this utility model proposes an aluminum alloy polishing device.

[0005] The present invention proposes an aluminum alloy polishing device, which includes a mounting frame, two support plates, two pressure plates, a support base, a polishing assembly, and a driving assembly.

[0006] The inner wall of the mounting bracket is provided with multiple slots;

[0007] The support plate is fixedly connected inside the mounting frame, and a hydraulic cylinder is fixedly connected to the inner wall of each of the two support plates. Two guide rods are slidably connected to the inner wall of each support plate.

[0008] The top of the pressure plate is fixedly connected to the corresponding hydraulic cylinder output end and guide rod. The bottom of the pressure plate has multiple pressure grooves, and multiple rubber strips are fixedly connected to the inner wall of each pressure groove.

[0009] The support base is slidably connected to the inner wall of the mounting frame, and the top of the support base is fixedly connected to the corresponding hydraulic cylinder output end and guide rod.

[0010] The grinding assembly is installed inside the support base;

[0011] The drive component is used to drive the grinding component to rotate.

[0012] Preferably, the grinding assembly includes multiple rotating columns, each of which is rotatably connected to the inner wall of the support base. Each rotating column has a toothed ring fixedly connected to its outer wall, with adjacent toothed rings meshing with each other. A cross groove is formed on the inner wall of the rotating column.

[0013] Preferably, a first arm is slidably connected to each of the two opposite ends of the cross groove, and a grinding plate is fixedly connected to the outer wall of each of the first arms.

[0014] Preferably, a second arm is slidably connected to each of the other two opposite ends of the cross groove, and a cleaning brush is fixedly connected to the outer wall of each of the second arms.

[0015] Preferably, each of the inner walls of the rotating column is rotatably connected to a first adjusting screw, and each of the inner walls of the rotating column is rotatably connected to a second adjusting screw. The two ends of the first adjusting screw are respectively threaded to the first support arm, and the two ends of the second adjusting screw are respectively threaded to the second support arm.

[0016] Preferably, the drive assembly includes a drive shaft, the end of which passes through and is rotatably connected to a support base, and a gear is fixedly connected to the outer wall of the drive shaft, the gear meshing with a gear ring.

Compared with the traditional single-piece fixing method, multiple workpieces can be fixed at one time, so that the device can polish multiple aluminum alloy parts at the same time, improve processing efficiency and meet the needs of large-scale industrial production.

[0020] 2. In the grinding assembly, multiple rotating columns achieve synchronous rotation through meshing gear rings, ensuring that multiple grinding plates and cleaning brushes work simultaneously, thus improving grinding efficiency.

[0028] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model. In this utility model, unless otherwise expressly specified and limited, the term "fixed connection" should be interpreted broadly. For example, "fixed connection" can mean fixed installation, detachable connection, or integral; it can mean mechanical connection or electrical connection; it can mean direct connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] like Figures 1-3 As shown, an aluminum alloy polishing device includes a mounting frame 1, two support plates 3, two pressure plates 6, a support base 9, a polishing assembly, and a drive assembly. The inner wall of the mounting frame 1 is provided with multiple slots 2.

[0030] The support plate 3 is fixedly connected inside the mounting frame 1. Hydraulic cylinders 4 are fixedly connected to the inner walls of both support plates 3. Two guide rods 5 are slidably connected to the inner walls of the support plates 3. The top of the pressure plate 6 is fixedly connected to the output end of the corresponding hydraulic cylinder 4 and the guide rod 5. Multiple pressure grooves 7 are opened at the bottom of the pressure plate 6. Multiple rubber strips 8 are fixedly connected to the inner walls of the pressure grooves 7.

[0031] The support base 9 is slidably connected to the inner wall of the mounting frame 1, and the top of the support base 9 is fixedly connected to the output end of the corresponding hydraulic cylinder 4 and the guide rod 5.

[0032] The grinding assembly is installed inside the support base 9, and the drive assembly is used to drive the grinding assembly to rotate.

[0033] Mounting bracket 1 provides overall support and space for placing aluminum alloy cylinders. The slot 2 is used for positioning and initial support of the aluminum alloy cylinders. The support plate 3, hydraulic cylinder 4, and guide rod 5 form a lifting structure that can control the lifting of the pressure plate 6 and support seat 9 to achieve the pressing and fixing of aluminum alloy parts. The pressure plate 6, pressure slot 7, and rubber strip 8 work together to stably clamp multiple aluminum alloy cylinders using the elasticity of the rubber strip 8. Compared with the traditional single-piece fixing method, multiple workpieces can be fixed at one time, enabling the device to polish multiple aluminum alloy parts at the same time, improving processing efficiency and meeting the needs of large-scale industrial production.

[0034] like Figure 1 , Figure 4 and Figure 5 As shown, the grinding assembly includes multiple rotating columns 10, which are rotatably connected to the inner wall of the support base 9. Each rotating column 10 has a toothed ring 18 fixedly connected to its outer wall, with adjacent toothed rings 18 meshing with each other. A cross groove 11 is provided on the inner wall of the rotating column 10.

[0035] One of the opposite ends of the cross groove 11 is slidably connected to a first arm 14, and a grinding plate 15 is fixedly connected to the outer wall of the first arm 14.

[0036] The other two opposite ends of the cross groove 11 are slidably connected to a second arm 16, and a cleaning brush 17 is fixedly connected to the outer wall of the second arm 16.

[0037] The inner wall of the rotating column 10 is rotatably connected to a first adjusting screw 12, and the inner wall of the rotating column 10 is rotatably connected to a second adjusting screw 13. The two ends of the first adjusting screw 12 are threadedly connected to the first support arm 14, and the two ends of the second adjusting screw 13 are threadedly connected to the second support arm 16.

[0038] In the polishing assembly, multiple rotating columns 10 achieve synchronous rotation through meshing gear rings 18, ensuring that multiple polishing plates 15 and cleaning brushes 17 work simultaneously, thereby improving polishing efficiency.

[0039] The cross groove 11, the first support arm 14, the second support arm 16, the first adjusting screw 12 and the second adjusting screw 13 allow for flexible adjustment of the position of the grinding plate 15 and the cleaning brush 17 according to aluminum alloy cylinders with different inner diameters, making the device suitable for polishing aluminum alloy parts of various specifications and improving the versatility of the device.

[0040] like Figure 5 and Figure 6As shown, the drive assembly includes a drive shaft 19, the end of which passes through and is rotatably connected to the support base 9. A gear 20 is fixedly connected to the outer wall of the drive shaft 19, and the gear 20 meshes with the gear ring 18.

[0041] The drive assembly also includes a stepper motor 22, which is fixedly connected to the inner wall of the mounting bracket 1. A cross shaft 21 is fixedly connected to the output end of the stepper motor 22, and the end of the cross shaft 21 is slidably connected to the inner wall of the cross groove at the end of the transmission shaft 19.

[0042] In the drive assembly, the cross shaft 21 engages with the cross groove of the drive shaft 19 to achieve stable power transmission. At the same time, the cross shaft 21 can slide along the cross groove at the end of the drive shaft 19, which facilitates installation and disassembly.

[0043] Working principle: In use, first place multiple aluminum alloy cylinders in the groove 2 on the inner wall of the mounting bracket 1. Activate the hydraulic cylinder 4 on the inner wall of the support plate 3. The output end of the hydraulic cylinder 4 pushes the pressure plate 6 and the support seat 9 downwards along the guide rod 5. The rubber strip 8 in the bottom groove 7 of the pressure plate 6 contacts the top of the aluminum alloy cylinders. Utilizing the elastic deformation of the rubber strip 8, the multiple aluminum alloy cylinders are firmly pressed into the groove 2, completing the fixation of the aluminum alloy cylinders.

[0044] Next, based on the inner diameter of the aluminum alloy cylinder, rotate the first adjusting screw 12 and the second adjusting screw 13. The first adjusting screw 12 is threadedly connected to the first support arm 14. When rotated, it causes the first support arm 14 to slide within the cross groove 11, thereby adjusting the position of the grinding plate 15. The second adjusting screw 13 is threadedly connected to the second support arm 16. When rotated, it causes the second support arm 16 to slide within the cross groove 11, adjusting the position of the cleaning brush 17 so that the grinding plate 15 and the cleaning brush 17 are adapted to the inner diameter of the aluminum alloy cylinder.

[0045] Then, the stepper motor 22 on the inner wall of the mounting bracket 1 is started. The cross shaft 21 at the output end of the stepper motor 22 drives the transmission shaft 19 to rotate. The gear 20 on the outer wall of the transmission shaft 19 meshes with the gear ring 18 on the outer wall of the rotating column 10. Since the adjacent gear rings 18 mesh with each other, multiple rotating columns 10 are driven to rotate synchronously.

[0046] Hydraulic cylinder 4 pushes support base 9 to move, causing cleaning brush 17 and polishing plate 15 to extend into the aluminum alloy cylinder. When rotating column 10 rotates, it drives polishing plate 15 to polish the inner wall of aluminum alloy part, while cleaning brush 17 cleans debris from the polished surface. After polishing, hydraulic cylinder 4 reverses its movement, causing support base 9 to move in the opposite direction, and the polished aluminum alloy cylinder is removed.
