A motor 2 is fixedly connected to the back of the top of the worktable 1. A first polishing wheel 3 is fixedly connected to the output end of the motor 2. A second polishing wheel 4 is arranged on the right side of the first polishing wheel 3. Vertical blocks 5 are fixedly connected to both the front and back of the top of the worktable 1. A drive structure 6 is arranged on the front of the first polishing wheel 3. The drive structure 6 includes a first gear 61. The back of the first gear 61 is fixedly connected to the front of the first polishing wheel 3. A second gear 62 is arranged on the right side of the first gear 61. The back of the second gear 62 is fixedly connected to the front of the second polishing wheel 4. A drive tooth 63 meshes on the left side of the second polishing wheel 4. A first transmission tooth 64 is fixedly connected to the front of the drive tooth 63. A second transmission tooth 65 is arranged on the left side of the first transmission tooth 64. The second transmission tooth 65 and the first transmission tooth 64 are connected by a chain drive. A limit structure 7 is arranged on the top of the first polishing wheel 3 and the second polishing wheel 4.

[0022] refer to Figure 1 The limiting structure 7 includes a limiting plate 71, which is located on top of the first polishing wheel 3 and the second polishing wheel 4. Fixing blocks 72 are fixedly connected to the bottom of all four sides of the limiting plate 71. Telescopic cylinders 73 are fixedly connected to the bottom of the fixing blocks 72. The bottom of the telescopic cylinders 73 is fixedly connected to the top of the worktable 1.

[0023] As a technical optimization of this utility model, the limiting structure 7 can limit the material and prevent it from shaking and falling out of the first polishing wheel 3 and the second polishing wheel 4 during processing.

[0024] refer to Figure 4 A fixing rod 8 is fixedly connected to the back of the drive gear 63, and a bearing 9 is movably sleeved on the surface of the fixing rod 8. The back of the bearing 9 is fixedly connected to the front of the vertical block 5.

[0025] As a technical optimization of this utility model, the driving gear 63 can be positioned by setting the fixing rod 8 and the bearing 9 to prevent the driving gear 63 from shaking during operation.

[0026] refer to Figure 3 A through hole 10 is provided at the center of the top of the workbench 1, and guide blocks 11 are fixedly connected to both sides of the top of the through hole 10.

[0027] As a technical optimization of this utility model, the through hole 10 facilitates the collection of dust after grinding, and the guide block 11 facilitates the guidance of dust collection.

[0028] refer to Figure 3A collection box 12 is provided at the bottom of the through hole 10, and a support block 13 is provided at the bottom of the collection box 12. The top of the support block 13 is fixedly connected to the bottom of the workbench 1.

[0029] As a technical optimization of this utility model, the collection box 12 can be used to collect the processed dust, and the support block 13 can be used to support the collection box 12.

[0030] refer to Figure 3 Limiting grooves 14 are provided on both the front and back of the top of the vertical block 5. A limiting block 15 is slidably connected inside the limiting groove 14. The top of the limiting block 15 is fixedly connected to the bottom of the limiting plate 71.

[0031] As a technical optimization of this utility model, the limiting groove 14 and the limiting block 15 can limit the limiting plate 71 and prevent the limiting plate 71 from shaking when it is raised or lowered.

[0032] The working principle and usage process of this utility model are as follows: First, the telescopic cylinder 73 drives the fixed block 72 and the limiting block 15 to move upward, causing the limiting plate 71 to rise. The user places the material between the first polishing wheel 3 and the second polishing wheel 4, and then resets the limiting plate 71 to ensure that the material is firmly fixed between the two polishing wheels, preventing the material from falling off during processing. After starting the motor 2, the output end of the motor 2 rotates, driving the first polishing wheel 3 to start rotating. The rotation of the first polishing wheel 3 is transmitted through the chain between the first transmission gear 64 and the second transmission gear 65, causing the second transmission gear 65 to rotate synchronously. The rotation of the second transmission gear 65 further drives the drive gear 63 to rotate, and the drive gear 63 drives the second gear 62 to rotate, thereby causing the second polishing wheel 4 to start rotating as well. At this time, the first polishing wheel 3 and the second polishing wheel 4 rotate simultaneously, performing synchronous polishing processing on multiple sets of materials placed between them.

[0033] In summary, this dual-fuel steel-top aluminum-skirt piston polishing machine, through its drive structure, enables the motor's rotational force to be further transmitted to the second polishing wheel via gear and chain transmission, ensuring that both work in tandem. This drive structure not only achieves efficient transmission between the two polishing wheels but also ensures that multiple sets of materials can be polished simultaneously and uniformly, thereby improving overall processing efficiency. It solves the problem that existing polishing machines cannot achieve simultaneous processing of multiple sets of materials, leading to reduced processing efficiency and affecting the progress of subsequent processes and overall production efficiency.
