[0025] In order to make the technical problems, technical solutions, and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0026] Please refer to Figures 1 to 2 , and now the polishing device provided by the present utility model will be described. Generally speaking, the polishing device includes a polishing wheel 1 rotatably disposed on one side of a workpiece to be machined around its own axis. More specifically, the polishing wheel 1 includes a mounting roller 11, a rubber layer 12, and a friction layer 13. The mounting roller 11 is made of metal or thermosetting plastic. A plurality of insertion slots 111 are uniformly formed on the outer peripheral surface of the mounting roller 11 around its own axis, and the length direction of each insertion slot 111 is parallel to the axial direction of the mounting roller 11. The rubber layer 12 is coated on the outer peripheral surface of the mounting roller 11, and a first clamping protrusion 121 is provided on the side of the rubber layer 12 facing the mounting roller 11, and the first clamping protrusion 121 is inserted into the insertion slot 111; the friction layer 13 is connected to the outside of the rubber layer 12, and the friction layer 13 is a porous structure impregnated with grinding fluid.
[0027] Compared with the prior art, in the specific implementation process of this embodiment, the mounting roller 11 in this embodiment serves as a mounting base, and can utilize its own high hardness to improve the overall structural stiffness of the polishing wheel 1. During the process of rotating or moving the polishing wheel 1, the control accuracy of the polishing wheel 1 can be enhanced through the hard mounting roller 11 in this embodiment, thereby facilitating the control of the grinding accuracy of the polishing wheel 1 and improving the consistency of the tolerances of each part of the workpiece machined in this embodiment; in addition to the above advantages, in this embodiment, a stable connection between the rubber layer 12 and the mounting roller 11 can also be formed through the insertion and adaptation between the first clamping protrusion 121 and the insertion slot 111, preventing the rubber layer 12 from falling off the mounting roller 11 during the rotation of the polishing wheel 1. Moreover, the rubber layer 12 can enhance the elasticity of the polishing wheel 1, enabling the polishing wheel 1 in this embodiment to have the advantages of precise control while also being able to form a flexible polish on the workpiece to be machined by using the elastic rubber layer 12, improving the gloss of the surface of the workpiece.
[0028] Further, for the friction layer 13, in order to ensure the grinding effect of the friction layer 13 on the workpiece to be processed, a feasible implementation method is proposed. The material of the friction layer 13 is one or a combination of non-woven fabric, polyester fiber, and animal hair. In this way, the friction layer 13 can utilize its relatively loose characteristics to store grinding aids such as grinding fluid, thereby ensuring the polishing effect of this embodiment on the workpiece to be processed.
[0029] In addition to the above feasible implementation methods, during the specific implementation, the polishing wheel 1 will accumulate heat during the polishing process of the workpiece, which is likely to cause the rubber layer 12 to become loose. In order to prevent the rubber layer 12 from becoming loose from the mounting roller 11, a steel wire ring 122 is embedded in the rubber layer 12, and the steel wire ring 122 is coaxial with the mounting roller 11. In this embodiment, the steel wire ring 122 can enhance the tensile strength of the rubber layer 12, prevent the rubber layer 12 from becoming loose from the mounting roller 11 after heating and expanding, and improve the stability of the polishing wheel 1 in the present invention during use.
[0030] Based on the above embodiments, along the axis of the polishing wheel 1, one end of the insertion slot 111 is flush with the axial end face of the mounting roller 11, and the other end of the insertion slot 111 is flush with the axial end face of the other end of the mounting roller 11. The first clamping protrusion 121 can be inserted into the insertion slot 111 along the axial direction of the polishing wheel 1. Compared with the prior art, in this embodiment, a stable connection between the mounting roller 11 and the rubber layer 12 can be formed through the insertion fit between the first clamping protrusion 121 and the insertion slot 111. The assembly between the mounting roller 11 and the rubber layer 12 is more portable and is beneficial to preventing the rubber layer 12 from rotating relative to the mounting roller 11. Moreover, after the rubber layer 12 is heated and expanded, the connection between the first clamping protrusion 121 made of rubber and the insertion slot 111 is tighter, making it more difficult for the rubber layer 12 to become loose from the first mounting roller 11.
[0031] Based on the above embodiments, a feasible implementation method is proposed. Specifically, the polishing device further includes a driving mechanism 2 and a spraying mechanism. The driving mechanism 2 includes a driving motor 24, a machine base 23, a bearing seat 22, and a driving shaft 21. The bearing seat 22 is provided on the top of the machine base 23. The driving shaft 21 is provided in the bearing seat 22 and extends along the axial direction of the polishing wheel 1. Along the axis of the driving shaft 21, the polishing wheel 1 and the driving motor 24 are respectively located on both sides of the bearing seat 22. The driving motor 24 is provided on the bearing seat 22, and the driving motor 24 can drive the polishing wheel 1 to rotate through the driving shaft 21. The spraying mechanism includes a spraying pipeline provided on the machine base 23, and the nozzle of the spraying pipeline is inclined towards the friction layer 13. In this embodiment, the rotation of the driving motor 24 can drive the driving shaft 21 to rotate, and then drive the polishing wheel 1 to rotate. Moreover, the spraying mechanism in this embodiment can continuously spray liquids such as grinding fluid on the outer periphery of the polishing wheel 1, improving the grinding effect of the friction layer 13 on the workpiece.
[0032] As an alternative embodiment, an adhesive layer 14 is further provided between the rubber layer 12 and the friction layer 13, and the friction layer 13 is connected to the rubber layer 12 through the adhesive layer 14. In this way, the adhesion between the friction layer 13 and the rubber layer 12 is firm to prevent delamination between the friction layer 13 and the rubber layer 12.
[0033] Based on the above embodiments, the polishing wheel 1 further includes two side covers 15. The two side covers 15 are respectively disposed at both axial ends of the mounting roller 11, and the side covers 15 can form a shield for the rubber layer 12. With such a setting, the two side covers 15 in this embodiment can prevent the rubber layer 12 from falling off the mounting roller 11 and solve the technical problem that the rubber layer 12 is prone to axial offset along the mounting roller 11.
[0034] As a feasible embodiment, along the axis of the polishing wheel 1, the length of the first clamping protrusion 121 is less than the length of the insertion slot 111, and a second clamping protrusion is provided on the side of the side cover 15 facing the mounting roller 11. The second clamping protrusion is inserted into the insertion slot 111. With such a setting, the connection between the side cover 15 and the mounting roller 11 in this embodiment is more firm and is beneficial to improving the overall structural strength of the polishing wheel 1.
[0035] In summary, compared with the prior art, the polishing device provided by the present utility model has the following beneficial effects: First, the mounting roller 11 in this embodiment serves as a mounting base, and can utilize its relatively high hardness to improve the overall structural rigidity of the polishing wheel 1. Furthermore, during the process of rotating or moving the polishing wheel 1, the hard mounting roller 11 is used to enhance the control accuracy of the polishing wheel 1, so as to facilitate controlling the grinding accuracy of the polishing wheel 1 and improving the consistency of the tolerances of various parts of the parts processed by the present utility model. Second, the present utility model can also form a stable connection between the rubber layer 12 and the mounting roller 11 through the insertion and adaptation between the first clamping protrusion 121 and the insertion slot 111, and use the second clamping protrusion to position the first clamping protrusion 121 to prevent the rubber layer 12 from falling off the mounting roller 11 during the rotation of the polishing wheel 1. Moreover, the rubber layer 12 can enhance the elasticity of the polishing wheel 1, enabling the polishing wheel 1 in the present utility model to have the advantages of precise control while also being able to form flexible polishing of the parts to be processed by using the elastic rubber layer 12, improving the glossiness of the part surface.
[0036] Based on the same inventive concept, the present utility model also proposes a production line, which includes the polishing device described above.
[0037] Compared with the prior art, the production line in the present utility model has all the beneficial effects of the above polishing device, and will not be elaborated here.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
