[0007] By adopting the above technical solution, the arc structure can adapt to the complex shape of automotive plastic parts, ensuring that the polishing surface can fit tightly. The gradually shrinking insertion part allows the polishing part to more easily enter and fit into hard-to-reach areas such as the grooves of the polished automotive plastic parts, achieving a comprehensive and in-depth polishing effect and meeting the polishing needs more specifically.

[0008] Optionally, the insert portion is provided with a chamfer.

[0011] Optionally, the fixing piece is a Velcro, which fits and covers the polishing seat and the polishing piece, with the hook surface of the Velcro facing away from the polishing seat, and the sandpaper is adhered to the hook surface of the Velcro.

[0012] Optionally, the Velcro includes a fixing portion and a polishing portion, the fixing portion is bonded to the polishing seat; a part of the polishing portion is bonded to the polishing seat, and the other part is bonded to the polishing piece.

[0013] Optionally, the grinding seat is provided with a water inlet and a water outlet which are interconnected, the water inlet is provided on the side of the grinding seat, and the water outlet passes through the side of the grinding seat where the grinding piece is provided.

[0014] Optionally, a water inlet and a water outlet are provided on the grinding seats on both sides of the length direction of the grinding piece.

[0015] Optionally, the central axis of the water inlet and the water outlet is arranged perpendicularly.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. The curved structure can adapt to the complex shapes of automotive plastic parts, ensuring that the polishing surface can fit tightly. The gradually shrinking insert allows the polishing piece to more easily enter and fit into hard-to-reach areas such as grooves of automotive plastic parts, achieving a comprehensive and in-depth polishing effect and more targeted to meet polishing needs.

[0018] 2. Chamfering helps reduce friction and resistance between the grinding workpiece and the part to be ground, allowing the grinding workpiece to enter and fit the complex shape area more smoothly, and maintain stable contact and uniform cutting force during the grinding process.

[0022] The following is combined with Figure 1-2 This application is described in further detail.

[0023] The embodiment of the present application discloses a contour grinding mechanism. Figure 1 The contour grinding mechanism includes a grinding base 1, on which is disposed a grinding piece 2, which is welded or integrally formed with the grinding base 1. Both sides of the grinding piece 2 are configured as arc-shaped structures, which are the two sides of the length direction of the grinding piece 2 and gradually approach each other along one side of the grinding base 1 and away from the grinding base 1, forming an insertion portion 3. The cross-section of the insertion portion 3 is a triangular structure. This allows the insertion portion 3 to be easily inserted into the groove of the automotive plastic part, and the arc structure can conform to the plastic part for grinding, thereby achieving a comprehensive and in-depth grinding effect and more targeted meeting the grinding needs.

[0024] In some embodiments, the insert portion 3 is provided with a chamfer 4. The chamfer 4 helps reduce friction and resistance between the insert portion 3 and the portion to be polished 52 during the polishing process, allowing the polishing member 2 to more smoothly enter and conform to complex shapes, while maintaining stable contact and uniform cutting force during the polishing process. The radius of the chamfer 4 can be adjusted according to actual needs.

[0025] In some embodiments, sandpaper (not shown in the figure) is detachably provided on the polishing piece 2, and the sandpaper can be selected with different mesh sizes according to different polishing requirements, so as to better adapt to different needs.

[0026] In some embodiments, the contour grinding mechanism further includes a fixing member, and the sandpaper is detachably fixed to the grinding member 2 via the fixing member.

[0027] Reference Figure 1 and Figure 2 In some embodiments, the fixing member is a Velcro 5, which fits and covers the polishing seat 1 and the polishing piece 2. The hook surface of the Velcro 5 faces the side away from the polishing seat 1, and the sandpaper is adhered to the hook surface of the Velcro 5. The Velcro 5 includes a fixing portion 51 and a polishing portion 52. The fixing portion 51 and the polishing portion 52 are integrally formed. The width of the fixing portion 51 is consistent with the width of the polishing seat 1 and is adhered to the polishing seat 1; the width of the polishing portion 52 is consistent with the length of the polishing piece 2. A portion of the polishing portion 52 is adhered to the polishing seat 1, and the other portion is adhered to the polishing piece 2, and is tightly fitted with the circumference of the polishing piece 2, so that the polished shape can be guaranteed. A portion of the sandpaper is adhered to the fixing portion 51 for fixation, and the other portion is adhered to the polishing portion 52, so that polishing can be performed more stably. In other embodiments, the fixing member can also be a self-adhesive sticker, a buckle, a latch, etc.

[0028] Refer again Figure 1 In some embodiments, the grinding seat 1 is provided with a water inlet 6 and a water outlet 7 that are interconnected. The water inlet 6 is provided on the side of the grinding seat 1 and is close to the grinding piece 2. The water outlet 7 passes through the side of the grinding seat 1 where the grinding piece 2 is provided, so that cleaning can be carried out simultaneously during the grinding process, thereby improving work efficiency.

[0029] In some embodiments, a water inlet 6 and a water outlet 7 are provided on the grinding seat 1 on both sides of the grinding piece 2 in the longitudinal direction, so that both sides can be cleaned simultaneously during grinding, thereby improving efficiency.

[0030] In some embodiments, the water inlet 6 and the water outlet 7 are arranged perpendicular to the central axis.

[0031] The implementation principle of a contoured grinding mechanism in an embodiment of the present application is as follows: the arc-shaped structure can adapt to the complex shape of automobile plastic parts, ensuring that the grinding surface can fit tightly, and the gradually shrinking insertion part 3 allows the grinding piece 2 to more easily enter and fit into the grooves and other difficult-to-reach areas of the automobile plastic parts, thereby achieving a comprehensive and in-depth grinding effect and meeting the grinding needs more specifically.

[0032] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
