[0002] Existing polishing machines basically come with a polishing shoe for a specific product when they leave the factory, such as Figure 2 As shown, there is only a single polishing shoe, and the inner side of the polishing shoe has an arc-shaped surface. Since the arc-shaped surface on the inner side of the polishing shoe is only suitable for the polishing needs of matching products, the company needs to customize the polishing tooling in advance when switching to other products to make the workpiece surface fit the polishing block. However, the customized polishing tooling cycle is long, which affects the company's normal production conversion and increases the company's production costs.

[0003] Therefore, it is urgent to improve the existing polishing shoe to meet various usage requirements. Utility Model Content

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Example 1

[0024] A polishing device of a polishing machine comprises a polishing shoe 1 and a polishing block 2 arranged on the inner side of the polishing shoe 1; the polishing block 2 is detachably connected to the polishing shoe 1; and a side of the polishing block 2 away from the polishing shoe 1 is in a concave arc shape; a side of the polishing block 2 close to the polishing shoe 1 is not completely in close contact with the polishing shoe 1.

[0025] Working principle: The utility model changes the original polishing shoe 1 structure into a polishing structure composed of a polishing shoe 1 and a polishing block 2. The manufacturer only needs to equip polishing blocks 2 of different specifications, that is, polishing blocks 2 with concave arcs of different sizes. When changing models and converting production, only the polishing block 2 needs to be replaced to meet the processing needs of different workpieces; specifically, the material of the polishing shoe 1 of the utility model is No. 45 steel, which can ensure the rigidity of the polishing shoe 1; the material of the polishing block 2 is No. 90 polyurethane, which can improve the friction coefficient with the sanding belt while having better rigidity, avoiding the slipping of the sanding belt during polishing, and at the same time having better plasticity, ensuring the fit between the workpiece surface and the polishing block 2 during polishing, thereby improving the roughness and cylindricity of the product after polishing.

[0026] In this embodiment, the inner side surface of the polishing shoe 1 is arc-shaped, U-shaped, V-shaped, W-shaped or wavy; this can provide different accommodating spaces for the polishing block 2 to be inserted into the polishing shoe 1, and the polishing block 2 can be fixed from different positions and angles, so that the polishing block 2 is placed more stably in the inner space of the polishing shoe 1.

[0027] In this embodiment, a side surface of the polishing block 2 close to the polishing shoe 1 matches the inner side profile of the polishing shoe 1, so that the polishing block 2 and the polishing shoe 1 have a better fit and a better fixing effect therebetween.

[0028] In this embodiment, when the inner side surface of the polishing shoe 1 or the side surface of the polishing block 2 close to the polishing shoe 1 has a sharp corner, the sharp corner is an arc chamfer 11 to reduce stress concentration or pressure damage during use.

[0029] In this embodiment, a certain gap is left between the sharp corner of the polishing block 2 on one side close to the polishing shoe 1 and the polishing shoe 1 to prevent the sharp corner of the polishing block 2 from damaging the inner side of the polishing shoe 1 .

[0030] In this embodiment, when the inner side surface of the polishing shoe 1 is U-shaped, the side surface of the polishing block 2 close to the polishing shoe 1 is U-shaped, and the two sharp corners of the polishing block 2 are wedge-shaped surfaces 23, so that during polishing, the polishing block 2 and the polishing shoe 1 remain stable without causing excessive pressure on the polishing shoe 1.

[0031] In this embodiment, a plurality of fixing members 3 are provided on the polishing shoe 1, and the fixing members 3 penetrate through the polishing shoe 1 and extend into the polishing block 2. Specifically, in this embodiment, the fixing members 3 are screws. The screws hold the polishing block 2 tightly against the polishing shoe 1, and can extend from the outside of the polishing shoe 1 into the inside of the polishing block 2 to connect it, or can extend from the outside of the polishing shoe 1 to the side of the polishing block 2 to tighten it. The upper and lower sides of the polishing block 2 are also supported by screws to prevent the polishing block 2 from loosening and maintain the stability of the connection between the polishing block 2 and the polishing shoe 1.

[0032] In this embodiment, a plurality of the fixing members 3 are evenly arranged along the outer peripheral surface of the polishing shoe 1 , thereby improving the connection stability between the polishing block 2 and the polishing shoe 1 .

[0033] In this embodiment, both ends of the concave arc surface 21 on the outer side of the polishing block 2 and the edge of the polishing block 2 have a platform transition surface 22 to avoid stress concentration from damaging the polishing block 2 or the polishing shoe 1 .

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
