Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of workpiece polishing, in particular to a polishing shaft and a polishing machine. BACKGROUND

[0002] In the production process, some workpieces need to be polished. In the related art, a polishing piece for polishing is mounted on a rotating shaft, and the workpiece is polished by rotating the polishing piece. However, the polishing piece is easy to be separated from the rotating shaft, thereby affecting the safety and efficiency of the polishing operation. CONTENT OF THE UTILITY MODEL

[0003] Therefore, the present application provides a polishing shaft and a polishing machine to improve the assembly stability of the polishing piece and the polishing shaft.

[0004] An embodiment of the present application provides a polishing shaft for being mounted on a polishing machine and assembling a polishing piece to polish a workpiece. The polishing shaft comprises a connecting section and an assembling section. The connecting section is used to connect with the polishing machine to rotate. The assembling section is connected with the connecting section to rotate with the connecting section. At least part of the circumferential side of the assembling section is provided with an assembling surface. The assembling surface is used to assemble the polishing piece. The radial width of the assembling surface gradually increases along the axial direction.

[0005] When the connecting section is driven to rotate by a driving mechanism, the assembling section rotates together, thereby driving the polishing piece assembled by the assembling surface to rotate to polish the workpiece. The radial width of the assembling surface gradually increases along the axial direction of the polishing shaft, which facilitates the assembling surface to hinder the movement of the polishing piece in the axial direction. On the one hand, it is convenient to assemble the polishing piece from the thinner part to the assembling surface. On the other hand, it reduces the possibility of the polishing piece separating from the polishing piece at the thicker part, thereby improving the assembly stability of the polishing piece and the polishing shaft.

[0006] In some embodiments of the present application, the assembling surface is arranged around the entire circumferential side of the assembling section.

[0007] The polishing piece can be assembled around the polishing shaft through the assembling surface. In the process of rotating the polishing shaft, the polishing piece can continuously provide the polishing operation on the workpiece.

[0008] In some embodiments of the present application, the assembling section is connected to one side of the connecting section along the axial direction, and the radial width of the assembling surface gradually increases in the direction close to the connecting section.

[0009] The assembling surface can hinder the movement of the polishing piece to the connecting section, so that the polishing piece can receive the force deviated to the connecting section, thereby facilitating the movement of the workpiece in the direction from the assembling section to the connecting section for polishing when the workpiece is polished, which is convenient to operate.

[0010] In some embodiments of the present application, the circumferential side of the assembling section is provided with a groove. The groove extends along the circumferential direction.

[0011] The recesses can axially hinder the movement of the polishing piece, and can improve the stability of the assembly between the polishing shaft and the polishing piece.

[0012] In some embodiments of the present application, the peripheral side of the assembly section is provided with a threaded groove, which surrounds the peripheral side of the assembly section and extends in the axial direction.

[0013] The threaded groove can help form a threaded fit between the polishing piece and the assembly section, and facilitate the assembly or disassembly between the polishing shaft and the polishing piece.

[0014] In some embodiments of the present application, the direction in which the polishing machine drives the connection section to rotate is the same as the spiral direction of the threaded groove.

[0015] When the polishing piece is polishing a workpiece, the polishing piece can move or have a tendency to move in the axial direction to the side where the radial width of the assembly surface is increased, and the inner diameter of the polishing piece has an upper limit, which can help tighten the polishing piece and the polishing shaft, thereby improving the stability of the assembly between the polishing piece and the polishing shaft.

[0016] In some embodiments of the present application, the connection section is provided with a shaft hole and a key groove. The shaft hole and the key groove are used to connect the polishing machine. The shaft hole is formed at one end of the connection section. The key groove is located on one side of the shaft hole in the radial direction, so that the connection section is fixed relative to the polishing machine.

[0017] The connection section is connected and fitted with the polishing machine through the shaft hole, which can facilitate the rotation of the polishing shaft around a certain axis. The key groove is connected and fitted with the polishing machine, which hinders the relative movement of the polishing shaft and the polishing machine in the rotation direction of the polishing shaft, so that the polishing shaft is fixed to the polishing machine for rotation.

[0018] In some embodiments of the present application, the connection section includes a fixed part and a deformation part. The fixed part and the deformation part are circumferentially arranged to form at least part of the shaft hole. One side of the fixed part and one side of the deformation part are separated, and the other side of the fixed part and the other side of the deformation part are connected. The deformation part itself can be deformed and / or the deformation part can be deformed relative to the fixed part, so that the sides of the fixed part and the deformation part that are separated from each other are close to each other in the circumferential direction.

[0019] By making the sides of the deformation part and the fixed part that are separated from each other close to each other, the hole diameter of the corresponding part of the shaft hole can be reduced, which can improve the stability of the assembly between the connection section and the driving shaft of the driving mechanism. And by making the sides of the deformation part and the fixed part that are separated from each other away from each other, the hole diameter of the corresponding part of the shaft hole can be expanded, which can facilitate the assembly or disassembly between the polishing shaft and the driving mechanism.

[0020] An embodiment of the present application provides a polishing machine. The polishing machine includes a driving mechanism and a polishing shaft as in any of the above embodiments. The driving mechanism connects the connection section of the polishing shaft to drive the polishing shaft to rotate.

[0021] The driving mechanism drives the polishing shaft to rotate, and the workpiece is polished by assembling the polishing piece to the polishing shaft. The polishing piece can be assembled to the assembling surface of the polishing shaft, thereby improving the stability of the assembly between the polishing shaft and the polishing piece, and facilitating the safety and efficiency of the polishing operation on the workpiece.

[0022] In some embodiments of the present application, the polishing machine further comprises a polishing piece. The polishing piece is detachably connected to the assembling section.

[0023] The polishing machine can replace the polishing piece without disassembling the polishing shaft, thereby simplifying the maintenance and replacement operation of the polishing piece. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.​​

[0033] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0034] Embodiments of the present application provide a polishing shaft for being mounted on a polishing machine and assembling a polishing piece to polish a workpiece. The polishing shaft comprises a connecting section and an assembling section. The connecting section is used to connect with the polishing machine to rotate. The assembling section is connected with the connecting section to rotate with the connecting section. At least part of the assembling section is provided with an assembling surface on the circumferential side. The assembling surface is used to assemble the polishing piece. The radial width of the assembling surface gradually increases along the axial direction.

[0035] When the connecting section is driven to rotate by the driving mechanism, the assembling section rotates together, thereby driving the polishing piece assembled by the assembling surface to rotate to polish the workpiece. The radial width of the assembling surface gradually increases along the circumferential direction of the polishing shaft, which facilitates the assembling surface to hinder the movement of the polishing piece in the axial direction, on the one hand, facilitating the assembling of the polishing piece from the thinner part to the assembling surface, and on the other hand, reducing the possibility of the polishing piece separating from the polishing piece from the thicker part, thereby improving the assembling stability of the polishing piece and the polishing shaft.

[0036] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0037] Referring to Figure 1 Embodiments of the present application provide a polishing machine 200 for polishing a workpiece (not shown in the figure).

[0038] In some embodiments, the workpiece comprises a shell or frame of various digital products or digital accessories. In other embodiments, the workpiece can be various other products that need to be polished and polished, such as various hardware.

[0039] In some embodiments, the polishing machine 200 comprises a driving mechanism 201 and a polishing shaft 100. The driving shaft 2011 of the driving mechanism 201 is connected with the polishing shaft 100 to drive the polishing shaft 100 to rotate, thereby being used to polish the workpiece. As an exemplary example, the driving mechanism 201 can be a motor.

[0040] In some embodiments, the polishing machine 200 further comprises a polishing piece 202. The polishing piece 202 is detachably connected to the polishing shaft 100. The driving mechanism 201 drives the polishing shaft 100 to rotate, and the workpiece is polished by assembling the polishing piece 202. The polishing machine 200 does not need to disassemble the polishing shaft 100, and the polishing piece 202 can be replaced, thereby simplifying the maintenance and replacement operation of the polishing piece 202.

[0041] In some embodiments, the polishing member 202 comprises a cloth 2021 for polishing. The workpiece is polished by rubbing against the cloth 2021. In some embodiments, the polishing member 202 further comprises a foam 2022. The cloth 2021 is arranged around the foam 2022. The foam 2022 is assembled to the polishing shaft 100. By arranging the foam 2022, the impact between the workpiece and the polishing shaft 100 is reduced. In some embodiments, the polishing member 202 further comprises a bushing 2023. The foam 2022 is assembled to the polishing shaft 100 through the bushing 2023. By arranging the bushing 2023, the assembly connection between the polishing member 202 and the polishing shaft 100 is facilitated.

[0042] In the present application, the reference bases for the axial, radial, circumferential, and peripheral directions are the rotation axis X of the polishing shaft 100.

[0043] Referring to Figure 1 and Figure 2 In some embodiments, the polishing shaft 100 comprises a connecting section 1 and an assembly section 2. The connecting section 1 is used to connect to the driving mechanism 201 of the polishing machine 200 for rotation. The assembly section 2 is connected to the connecting section 1 to rotate with the connecting section 1. At least part of the peripheral side of the assembly section 2 is provided with an assembly surface 21. The assembly surface 21 is used to assemble the polishing member 202. The radial width of the assembly surface 21 gradually increases along the axial distance. Among them, the polishing member 202 can be assembled only in the assembly surface 21 part of the assembly section 2; the polishing member 202 can also be partially assembled in the assembly surface 21 part of the assembly section 2 and partially assembled outside the assembly surface 21 of the assembly section 2. The radial width of a certain place of the assembly surface 21 refers to the distance of the assembly surface 21 at that place to the rotation axis X of the polishing shaft 100 along the radial direction.

[0044] When the connecting section 1 is driven to rotate by the driving mechanism 201, the assembly section 2 rotates together, thereby driving the polishing member 202 assembled by the assembly surface 21 to rotate to polish the workpiece. And along the axial direction of the polishing shaft 100, the radial width of the assembly surface 21 gradually increases, which facilitates the assembly surface 21 to hinder the movement of the polishing member 202 in the axial direction, on the one hand, it is convenient to assemble the polishing member 202 from the thinner part to the assembly surface 21, on the other hand, it reduces the possibility of the polishing member 202 from the thicker part to separate from the polishing member 202, thereby improving the assembly stability of the polishing member 202 and the polishing shaft 100, and further improving the safety and efficiency of the workpiece polishing operation.

[0045] In some embodiments, the assembly surface 21 is arranged around the entire peripheral side of the assembly section 2. The polishing member 202 can be assembled around the polishing shaft 100 through the assembly surface 21, and in the process of rotating the polishing shaft 100, the polishing member 202 can continuously provide the polishing operation to the workpiece.

[0046] It can be understood that in some embodiments, the assembly section 2 can be partially provided with the assembly surface 21, or can be entirely provided with the assembly surface 21. It can be understood that in some embodiments, the assembly surface 21 is arranged on the entire circumferential side of the assembly section 2. In other embodiments, referring to Figure 3 , the assembly surface 21 is arranged on only part of the circumferential side of the assembly section 2, and is not arranged on the entire circumferential side.

[0047] Referring to Figure 2 , it can be understood that in some embodiments, the assembly surface 21 is in the shape of a conical surface. In other embodiments, referring to Figure 4 , the assembly surface 21 is in the shape of a side surface of a circular truncated cone.

[0048] Referring to Figure 1 and Figure 2 , in some embodiments, the assembly section 2 is connected to one side of the connecting section 1 in the axial direction. The radial width of the assembly surface 21 gradually increases in the direction close to the connecting section 1. The assembly surface 21 can hinder the polishing member 202 from moving towards the connecting section 1, so that the polishing member 202 can receive the force tending to move towards the connecting section 1, and facilitate the movement of the workpiece in the direction from the assembly section 2 to the connecting section 1 for polishing, which is convenient to operate.

[0049] In other embodiments, referring to Figure 4 , in the axial direction of the polishing shaft 100, the radial width of the assembly surface 21 gradually increases in the direction away from the connecting section 1. The polishing member 202 can be assembled to the polishing shaft 100 from the side of the connecting section 1.

[0050] Referring to Figure 2 and Figure 4 , in some embodiments, the circumferential side of the assembly section 2 is provided with a groove (not shown in the figure). The groove extends in the circumferential direction. The groove can hinder the movement of the polishing member 202 in the axial direction, which is conducive to improving the stability of the assembly between the polishing shaft 100 and the polishing member 202. The groove can be entirely arranged in the assembly surface 21, or can be partially arranged in the assembly surface 21 and partially arranged outside the assembly surface 21.

[0051] Referring to Figure 1 and Figure 2 , in some embodiments, the circumferential side of the assembly section 2 is provided with a threaded groove 22. The threaded groove 22 is arranged around the circumferential side of the assembly section 2 and extends in the axial direction. The threaded groove 22 helps to form a threaded fit between the polishing member 202 and the assembly section 2, which facilitates the assembly or disassembly between the polishing shaft 100 and the polishing member 202.

[0052] In other embodiments, the threaded groove 22 can also be arranged in sections.

[0053] In some embodiments, the driving mechanism 201 drives the connecting section 1 to rotate in the same direction as the thread helix direction of the thread groove 22. The thread helix direction refers to the direction of rotating outward from the position close to the axis.

[0054] When the polishing member 202 polishes the workpiece, the polishing member 202 can move or has a tendency to move to the side where the radial width of the assembly surface 21 increases, and the inner diameter of the polishing member 202 has an upper limit, which is beneficial to tighten the polishing member 202 and the polishing shaft 100, thereby improving the stability of the assembly between the polishing member 202 and the polishing shaft 100.

[0055] It can be understood that, in some embodiments, the bushing 2023 of the polishing member 202 is threadedly connected with the assembly section 2 through the thread groove 22. In some embodiments, the foam 2022 of the polishing member 202 is threadedly connected with the assembly section 2 through the thread groove 22.

[0056] In some embodiments, the connecting section 1 is provided with an axle hole 11 and a key groove 12. The axle hole 11 and the key groove 12 are used for connecting the driving shaft 2011 of the driving mechanism 201 of the polishing machine 200. The axle hole 11 is arranged at one end of the connecting section 1. The key groove 12 is arranged on one side of the axle hole 11 in the radial direction, so as to fix the connecting section 1 relative to the driving mechanism 201 of the polishing machine 200.

[0057] The connecting section 1 is connected and matched with the driving shaft 2011 of the driving mechanism 201 through the axle hole 11, so as to facilitate the rotation of the polishing shaft 100 around the axis. The key groove 12 is connected and matched with the driving shaft 2011 of the driving mechanism 201, which hinders the relative movement between the polishing shaft 100 and the driving shaft 2011 in the rotation direction of the polishing shaft 100, so as to fix the polishing shaft 100 to the driving shaft 2011 of the driving mechanism 201 for rotation.

[0058] It can be understood that, in some embodiments, the key groove 12 is in communication with the axle hole 11 on one side of the axle hole 11 in the radial direction.

[0059] In some embodiments, the connecting section 1 comprises a fixed part 13 and a deformed part 14. The fixed part 13 and the deformed part 14 are arranged to form at least part of the axle hole 11. One side of the fixed part 13 and one side of the deformed part 14 are arranged to be spaced apart, and the other side of the fixed part 13 and the other side of the deformed part 14 are connected. The deformed part 14 can be deformed by itself and / or the deformed part 14 can be deformed relative to the fixed part 13, so that the sides of the fixed part 13 and the deformed part 14 that are separated from each other are close to each other in the circumferential direction. The two sides of the deformed part 14 in the axial direction are separated from other structures of the connecting section 1, so as to facilitate the deformation of the deformed part 14 by itself or the deformation of the deformed part 14 relative to the fixed part 13. The key groove 12 is arranged on the fixed part 13.

[0060] By making the side of the deformation part 14 and the fixed part 13 separated from each other close to each other, the hole diameter of the corresponding part of the shaft hole 11 can be reduced, which can improve the stability of the assembly between the connecting section 1 and the driving shaft 2011 of the driving mechanism 201. And by making the side of the deformation part 14 and the fixed part 13 separated from each other away from each other, the hole diameter of the corresponding part of the shaft hole 11 can be enlarged, which facilitates the assembly or disassembly between the polishing shaft 100 and the driving mechanism 201.

[0061] In some embodiments, the fixed part 13 and the deformation part 14 are integrally arranged. In other embodiments, the fixed part 13 and the deformation part 14 can be hingedly arranged.

[0062] In some embodiments, the polishing machine 200 further comprises a fastener (not shown in the figure). The fastener passes through the side of the deformation part 14 and the fixed part 13 separated from each other to fix the relative position of the deformation part 14. Wherein, the fastener can be a screw or a bolt.

[0063] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not used as a limitation to the present application. Any appropriate changes and variations made to the above embodiments within the spirit and principles of the present application fall within the scope of the present application.
