For those skilled in the art, the specific meaning of the above-mentioned terms in the present application can be understood according to the specific circumstances.

[0062] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0063] Please refer to Figure 1 The embodiment of the present application provides a polishing device 100, the polishing device 100 includes a connecting assembly 10, a polishing assembly 20 and a bearing 30, for polishing workpieces. Wherein, the workpiece can be a mobile phone frame, metal plate and the like, which is not shown in the drawings.

[0064] Please refer to Figures 1 to 3 The connecting assembly 10 includes a bearing connecting piece 11. The bearing 30 includes a rotatingly connected outer ring 31 and an inner ring 32. The outer ring 31 is connected to the bearing connecting piece 11, and the inner ring 32 is connected to the polishing assembly 20.

[0065] The polishing device 100 described above, by setting the outer ring 31 connected with the bearing connecting piece 11, the inner ring 32 connected with the polishing assembly 20, the bearing connecting piece 11 drives the outer ring 31 to rotate under the action of external force, so that the outer ring 31 can drive the inner ring 32 to rotate through the bearing ball, and in turn drive the polishing assembly 20 to rotate, so that the polishing assembly 20 polishes the workpiece. When the pressing force applied by the polishing assembly 20 to the workpiece is too large, the friction between the polishing assembly 20 and the workpiece also increases, and the polishing assembly 20 and the inner ring 32 stop rotating. Since the inner ring 32 is rotationally connected with the outer ring 31, it can prevent the outer ring 31 and the inner ring 32 from being stuck with each other, thereby avoiding the phenomenon that the workpiece is over- polished and the edge collapses when the pressing force applied by the polishing assembly 20 to the workpiece is too large, and in turn improving the polishing precision.

[0066] Referring to Figure 3 and Figure 4 In some embodiments, the polishing assembly 20 includes a polishing head 21, a locking piece 22, and a locking gasket 23. One end of the polishing head 21 is arranged in the bearing hole 33 of the bearing 30, and the other end of the polishing head 21 is used for polishing the workpiece. One end of the locking piece 22 passes through the bearing hole 33 of the bearing 30 to connect the locking gasket 23, so as to lock the locking gasket 23 on the side of the inner ring 32 away from the polishing head 21, and the other end of the locking piece 22 is connected with the polishing head 21. Exemplarily, the locking piece 22 can be a bolt.

[0067] In this way, by connecting the locking piece 22 with the locking gasket 23 and the polishing head 21 respectively, the polishing head 21 is stably connected to the inner ring 32 through the locking piece 22 and the locking gasket 23, so that the inner ring 32 stably drives the polishing head 21 to rotate synchronously, achieving precise polishing of the workpiece, and at the same time forming a split connection structure between the polishing assembly 20 and the bearing 30, facilitating the installation of the polishing assembly 20 to the inner ring 32 of the bearing 30.

[0068] In other embodiments, the polishing head 21 is provided with external threads adjacent to the end periphery of the inner ring 32, and the hole wall of the bearing hole 33 is provided with matching internal threads, and the polishing head 21 is threadedly connected with the bearing hole 33, which can also achieve the split connection structure between the polishing assembly 20 and the bearing 30.

[0069] Referring to Figure 2 and Figure 3 In some embodiments, the polishing head 21 is provided with an eccentric hole 211 adjacent to one side of the inner ring 32, and the locking piece 22 is arranged in the eccentric hole 211. The eccentric hole 211 described above is arranged in a different axis with the central axis L of the bearing connecting piece 11.

[0070] Thus, by arranging the locking piece 22 to pass through the eccentric hole 211, the polishing head 21 is arranged eccentrically relative to the bearing connecting piece 11, so that the polishing head 21 vibrates eccentrically relative to the bearing connecting piece 11 when polishing the workpiece, which is beneficial to improve the polishing efficiency.

[0071] Please refer to Figure 4 In some embodiments, the connecting assembly 10 further comprises a vibration adjusting piece 12 connected to the bearing connecting piece 11.

[0072] Thus, by arranging the vibration adjusting piece 12 to be connected to the bearing connecting piece 11, the vibration adjusting piece 12 increases the vibration amplitude of the polishing head 21, further improving the polishing range of the polishing head 21.

[0073] Please refer to Figure 4 In some embodiments, the vibration adjusting piece 12 comprises a connecting portion 121 connected to the bearing connecting piece 11 and an adjusting portion 122 arranged outside the connecting portion 121.

[0074] Thus, by adjusting the connecting portion 121 to rotate relative to the bearing connecting piece 11, the adjusting portion 122 can be adjusted to a preset orientation according to the polishing requirement. When the adjusting portion 122 is in the same eccentric direction as the eccentric hole 211, the vibration amplitude of the polishing head 21 can be increased, and the polishing range and efficiency of the polishing head 21 can be improved. When the adjusting portion 122 is in a different eccentric direction from the eccentric hole 211, the vibration amplitude of the polishing head 21 can be reduced. Thus, the operator can adjust the orientation of the adjusting portion 122 according to the polishing requirement, and then control the vibration amplitude of the polishing head 21 and reduce the polishing range of the polishing head 21, so as to control the vibration amplitude and polishing range of the polishing head 21 by adjusting the orientation of the adjusting portion 122.

[0075] Specifically, in the present embodiment, the connecting portion 121 of the vibration adjusting piece 12 has a ring structure, the inner ring is a circular structure, and the outer ring is a circular notch structure, which is approximately D-shaped. The adjusting portion 122 is located at the notch position of the outer ring of the ring structure, so the outer periphery of the vibration adjusting piece 12 comprises an arc surface and a flat surface connected thereto. The adjusting portion 122 refers to the notch area of the flat surface of the vibration adjusting piece 12 away from the arc surface of the vibration adjusting piece 12. In other embodiments, the vibration adjusting piece 12 can also have other structures, as long as it can adjust the vibration amplitude and polishing range of the polishing head 21 according to the polishing requirement.

[0076] Please refer to Figure 3 and Figure 4In some embodiments, the vibration adjusting piece 12 further comprises a fixed locking portion 123, which comprises a fixed bolt 1231 and a bolt hole 1232 arranged in cooperation; wherein the bolt hole 1232 is arranged on the adjusting portion 122. Exemplarily, the fixed bolt 1231 can be a bolt, a screw or the like.

[0077] In this way, by cooperation of the fixed bolt 1231 and the bolt hole 1232, the fixed locking portion 123 can lock the connecting portion 121 to the bearing connecting piece 11, so that the vibration adjusting piece 12 and the bearing connecting piece 11 form a detachable connection structure, which facilitates the operator to timely adjust the orientation of the adjusting portion 122, and further adjust the vibration amplitude of the polishing head 21.

[0078] Please refer to Figure 2 and Figure 4 In some embodiments, the bearing connecting piece 11 is provided with a fixed groove 111 away from the polishing head 21, the fixed groove 111 is arranged in a non-axial manner with respect to the central axis L of the bearing connecting piece 11, and the bearing 30 is arranged in the fixed groove 111.

[0079] In this way, by arranging the fixed groove 111 in a non-axial manner with respect to the central axis L of the bearing connecting piece 11, the bearing 30 arranged in the fixed groove 111 is also arranged in a non-axial eccentric manner with respect to the central axis L of the bearing connecting piece 11, so that the inner ring 32 is driven to eccentrically vibrate by the outer ring 31, and further improve the vibration amplitude and polishing range of the polishing head 21 connected with the inner ring 32.

[0080] Specifically, in the present embodiment, the eccentric direction of the fixed groove 111 and the eccentric direction of the eccentric hole 211 are in the same eccentric direction, and further cooperate with each other to improve the vibration amplitude of the polishing head 21.

[0081] Please refer to Figure 2 and Figure 3 In some embodiments, the polishing device 100 further comprises a sealing cover 40, the sealing cover 40 comprises an avoiding hole 41 and a sealing portion 42; wherein the polishing head 21 passes through the avoiding hole 41 to connect the inner ring 32; the sealing portion 42 connects the bearing connecting piece 11; and the bearing 30 is located between the sealing portion 42 and the bearing connecting piece 11.

[0082] In this way, by connecting the sealing portion 42 to the bearing connecting piece 11, the bearing 30 located between the sealing portion 42 and the bearing connecting piece 11 can be sealed, so as to prevent the debris generated by the polishing head 21 polishing the workpiece from entering the inside of the bearing 30 and interfering with the normal operation of the bearing 30, which is conducive to improving the operation stability of the bearing 30. In addition, by passing through the avoiding hole 41, the avoiding hole 41 can avoid the interference between the polishing head 21 and the sealing portion 42.

[0083] Please refer toFigure 2 In some embodiments, a sealing ring 43 is embedded between the polishing head 21 and the escape hole 41.

[0084] In this way, since the polishing device 100 can be applied to a machine device, and the polishing head 21 polishes the workpiece to generate a large amount of debris, by arranging the sealing ring 43, the external oil stains and debris can be prevented from entering between the sealing part 42 and the bearing connecting piece 11 through the connection between the polishing head 21 and the escape hole 41, thereby facilitating the normal operation of the bearing 30.

[0085] Please refer to Figure 5 The embodiments of the present application also provide a polishing device 200, which comprises the polishing device 100 and a driving mechanism 201, and the connecting assembly 10 of the polishing device 100 further comprises a driving connecting rod 13, the bearing connecting piece 11 of the polishing device 100 is connected to one end of the driving connecting rod 13, and the driving mechanism 201 comprises a driving end 2011, which is connected to the other end of the driving connecting rod 13. Exemplarily, the driving end 2011 of the driving mechanism 201 can be a machine main shaft.

[0086] The above polishing device 200 utilizes the specific structure of the polishing device 100, and by arranging the outer ring 31 connected to the bearing connecting piece 11 and the inner ring 32 connected to the polishing head 21, the driving end 2011 drives the driving connecting rod 13 to drive the bearing connecting piece 11 to rotate, so that the outer ring 31 connected to the bearing connecting piece 11 generates a centripetal force and drives the inner ring 32 to drive the polishing head 21 to rotate synchronously, the driving end 2011 drives the bearing connecting piece 11 to drive the polishing head 21 to approach the workpiece, so that the polishing head 21 polishes the workpiece, when the pressing force of the workpiece by the polishing head 21 is too large, the friction between the polishing head 21 and the workpiece also increases, the polishing head 21 and the inner ring 32 stop rotating, since the inner ring 32 is rotationally connected to the outer ring 31, the outer ring 31 and the inner ring 32 can be prevented from being stuck to each other, so as to avoid the pressing force of the workpiece by the polishing head 21 being too large to cause the workpiece to be over-polished or to have a collapsed edge, thereby improving the polishing precision.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application rather than limit the present application, although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application.
