[0002] In the field of industrial manufacturing, castings such as automobile engine blocks, pump bodies, valve bodies, and hydraulic cylinders usually need to be polished with the help of polishing equipment to ensure that the inner wall has good smoothness after casting. This step is crucial to improving the performance and quality of the product. The smooth inner wall can effectively reduce friction resistance and optimize the working efficiency and stability of related components.

[0003] In the traditional polishing process of cylinder castings, a grinding motor is usually used to drive a grinding wheel to polish the inner wall. However, in the actual polishing process, as the grinding wheel continues to wear, it is difficult for it to always maintain a close fit with the polished part. This situation not only has an adverse effect on the polishing efficiency, but also reduces the polishing effect to a certain extent. This situation urgently needs to be improved and optimized to improve the quality and efficiency of cylinder casting polishing operations. Utility Model Content

[0021] When in use, first place the cylinder body to be polished on the table of the base 1 and clamp it with the clamp 2, then drive the grinding motor 4 and the convex hexagonal block 5 to slowly move downward through the lifting mechanism 3, and during the movement of the convex hexagonal block 5, manually press the grinding wheels 531 on both sides inward so that the grinding wheels 531 can enter the cylinder body, and after entering, drive the grinding motor 4 to drive the convex hexagonal block 5 to rotate, so that the inner wall of the cylinder body can be polished and polished by the grinding wheels 531. During the polishing process, because the two slide bars 53 are both subjected to the outward extension pressure of the spring 6, the grinding wheels 531 on both sides will always be tightly combined with the inner wall of the cylinder body, and the cylinder body will continue to be fitted and polished under the drive of the convex hexagonal block 5. Compared with the prior art, it can not only ensure the polishing effect but also improve the polishing efficiency.

[0022] It should be noted that if Figure 1As shown, the lifting mechanism 3 includes a hydraulic telescopic column 31 fixedly mounted on the top of the L-shaped support platform 11 and two directional rods 32 slidably connected to the L-shaped support platform 11, a fixed plate 33 is fixedly mounted between the lower surfaces of the hydraulic telescopic column 31 and the directional rods 32, a plurality of connecting rods 34 are fixedly mounted on the lower surface of the fixed plate 33, a central plate 35 is fixedly mounted between the lower surfaces of the plurality of connecting rods 34, a grinding motor 4 is fixedly mounted on the upper surface of the central plate 35, and the output shaft of the grinding motor 4 passes through the through opening of the central plate 35;

[0023] The extension and retraction of the hydraulic telescopic column 31 can drive the grinding motor 4 and the convex hexagonal block 5 to move, so that the inner wall of the cylinder body at different heights can be polished by using the grinding wheel 531.
