[0019] 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.

[0020] The purpose of this invention is to provide a polishing device that solves the problems existing in the prior art. It increases the connection area and connection strength between the polishing pad and the mounting wheel, making the polishing pad less prone to loosening or local wrinkling during the polishing process. This allows for long-term polishing operations and avoids the problem of frequent downtime for repair and replacement due to loose polishing pads, which reduces polishing efficiency.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-5As shown, this embodiment provides a polishing device, including a mounting platform 1, a mounting wheel 2, a polishing pad 3, Velcro 4, and a drive mechanism. The mounting wheel 2, polishing pad 3, and Velcro 4 constitute a polishing wheel. Specifically, the mounting platform 1 is equipped with a drive mechanism and the mounting wheel 2. The mounting wheel 2 is typically vertically positioned with its rotation axis horizontally. The drive mechanism is connected to the mounting wheel 2 for driving its rotation. One side of the Velcro 4 is fixed to the circumferential wall of the mounting wheel 2, and the other side of the Velcro 4 is fixed to the inner surface of the polishing pad 3. The Velcro 4 is used to fix the polishing pad 3 and the circumferential wall of the mounting wheel 2. Since the polishing pad 3 is replaced more frequently than the mounting wheel 2, the hook side of the Velcro 4 is usually fixed to the axial sidewall of the mounting wheel 2, and the rough side of the Velcro 4 is fixed to the inner surface of the polishing pad 3. The circumferential wall of the mounting wheel 2 is also provided with mounting holes with internal threads and fastening screws 5 threaded into the mounting holes. The nuts of the fastening screws 5 have a large area, which can press the polishing pad 3 to further fix the polishing pad 3. Along the radial direction of the mounting wheel 2, the end of the fastening screw 5 is located inside the circular polishing track of the polishing pad 3 to avoid the end of the fastening screw 5 contacting the workpiece surface and damaging the workpiece.

[0023] In this embodiment, by fixing Velcro 4 to the circumferential wall of the mounting wheel 2 and using Velcro 4 to fix the polishing pad 3, the polishing pad 3 can be connected to the circumferential wall of the mounting wheel 2 at all points. This increases the connection area and connection strength between the polishing pad 3 and the mounting wheel 2, making it less likely for the polishing pad 3 to loosen or wrinkle during the polishing process. This allows for long-term polishing operations and avoids the problem of frequent downtime for repair and replacement due to loose polishing pad 3, which reduces polishing efficiency.

[0024] To ensure the connection strength and flatness between the hook side of the Velcro 4 and the circumferential wall of the mounting wheel 2, in this embodiment, the hook side of the Velcro 4 is bonded to the circumferential wall of the mounting wheel 2. An adhesive backing can be provided on the back of the hook side of the Velcro 4, and a plastic film can be provided on the surface of the adhesive backing. When not in use, the plastic film protects the adhesive backing; when in use, the plastic film is removed, and the Velcro 4 is simply adhered to the circumferential wall of the mounting wheel 2 using the adhesive backing.

[0025] In this embodiment, the polishing pad 3 is a sponge abrasive, and the rough surface of the Velcro 4 can be directly formed on the inner surface of the polishing pad 3.

[0026] like Figure 3 , Figure 4As shown, in this embodiment, the mounting wheel 2 is provided with a radially inwardly extending groove 6, and the bottom of the groove 6 is provided with a radially extending mounting hole, which is an internally threaded hole. The two ends of the Velcro 4 are located at the top of the groove 6. After the fastening screw 5 presses the polishing pad 3 tightly, the polishing pad 3 adheres to the sidewall and bottom of the groove 6, which can tighten the polishing pad 3, increase the pressure of the polishing pad 3 on the circumferential wall of the mounting wheel 2, thereby improving the adhesion strength between the hook and loop surfaces of the Velcro 4, and reducing the possibility of the hook and loop connection failing, causing the polishing pad 3 to fall off. Specifically, one end of the polishing pad 3 is first located at the bottom of the groove 6, and the polishing pad 3 is pasted around the surface of the Velcro 4. The other end of the polishing pad 3 is located at the bottom of the groove 6, and then both ends of the polishing pad 3 are pressed and fixed. If it is inconvenient to simultaneously press both ends of the polishing pad 3 using the fastening screw 5, a pressing block 15 with a larger pressing area can be set in the groove 6. The fastening screw 5 passes through the pressing block 15 and connects to the mounting wheel 2, and the pressing block 15 is used to press both ends of the polishing pad 3.

[0027] In this embodiment, the radial cross-section of the groove 6 is a trapezoidal shape with the width gradually increasing from bottom to top, which facilitates the installation of the fastening screw 5 and also makes it easy for the polishing pad 3 to adhere tightly to the side wall and bottom of the groove 6. Furthermore, the clamping block 15 can be a trapezoidal shape that fits the groove, which can press the end of the polishing pad 3 tightly against the bottom and side wall of the groove 6.

[0028] In this embodiment, the mounting platform 1 is also provided with a driving wheel 7 and a driven wheel 8 connected by a transmission. The diameter of the driving wheel 7 is larger than that of the driven wheel 8. The driven wheel 8 is coaxially arranged with the mounting wheel 2. In this embodiment, the diameter of the driving wheel 7 is larger than that of the driven wheel 8, forming a speed-increasing structure, which can increase the rotational speed of the driven wheel 8 and the mounting wheel 2 and ensure the polishing effect.

[0029] In this embodiment, the drive mechanism includes a drive motor 9, a main drive wheel 10, and a secondary drive wheel 11. The output end of the drive motor 9 is fixed to the main drive wheel 10, and the main drive wheel 10 and the secondary drive wheel 11 are connected by a transmission. The secondary drive wheel 11 is coaxially arranged with the drive wheel 7. Meanwhile, other equipment, such as a grinding mechanism, can also be installed on the transmission shaft where the secondary drive wheel 11 and the drive wheel 7 are located. The drive motor 9, the main drive wheel 10, and the secondary drive wheel 11 simultaneously drive the grinding mechanism and the polishing wheel to perform operations.

[0030] In this embodiment, the driving wheel 7, driven wheel 8, main drive wheel 10, and auxiliary drive wheel 11 are all provided with teeth. The driving wheel 7 and driven wheel 8, as well as the main drive wheel 10 and auxiliary drive wheel 11, are connected by toothed belts to ensure the stability of power transmission between each transmission pair and avoid the belt slippage phenomenon caused by using traditional belts.

[0031] like Figure 2As shown, in this embodiment, the mounting platform 1 is also equipped with a tensioning wheel 12 for tensioning the toothed belt between the driving wheel 7 and the driven wheel 8. Specifically, the tensioning wheel 12 is mounted on a wheel frame 13. One end of the wheel frame 13 is connected to the mounting platform 1 by a bolt, and the other end of the wheel frame 13 is provided with an arc-shaped hole 14. Another bolt passes through the arc-shaped hole 14 and is connected to the mounting platform 1. The wheel frame 13 is pressed tightly by a nut, so that the wheel frame 13 can rotate around one end, thereby changing the contact force between the tensioning wheel 12 and the toothed belt, and realizing the tension adjustment of the toothed belt.

[0032] Any adaptive changes made according to actual needs are within the protection scope of this utility model.

[0033] This utility model uses specific examples to illustrate its principles and implementation methods.
