[0030] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application.

[0031] The electric vehicle wheel hub polishing device according to the embodiments of the present application will be described below with reference to the drawings.

[0032] As Figures 1 to 6 shown, the electric vehicle wheel hub polishing device according to the embodiments of the present application may include a support plate 1, a vertical plate 2, a turntable 3, a plurality of clamping assemblies 4, a support shaft 5, an alternating assembly 6, a second driving assembly 7, and two connecting mechanisms 8.

[0033] Among them, two slide table modules 10 are provided on the support plate 1. The vertical plate 2 is arranged on the slide of the slide table module 10. A through groove is provided through the vertical plate 2, and the turntable 3 is rotatably arranged in the through groove.

[0034] In the embodiments of the present application, the slide table module 10 can adjust the distance between the turntable 3 and the polishing grinding wheel 18, so as to facilitate the installation and disassembly of the wheel hub. The vertical plate 2 plays a supporting role for the turntable 3.

[0035] Furthermore, the turntable 3 is connected to an external driving mechanism. Through the driving mechanism, the turntable 3 can be driven to rotate, so as to drive the wheel hub to rotate, so as to facilitate the uniform polishing treatment of the wheel hub. It can be understood that the specific structure of the driving mechanism is well-known common knowledge in the art and will not be elaborated in detail in the present application.

[0036] Inside the turntable 3, there is a first accommodation cavity 30. Inside the first accommodation cavity 30, there is a first driving component 9. A plurality of clamping components 4 are respectively connected to the first driving component 9. Among them, the clamping component 4 is used to clamp the hub.

[0037] It should be noted that in this embodiment, at least three clamping components 4 are provided, and the clamping components 4 are annularly distributed. Through the first driving component 9, a plurality of clamping components 4 can be driven to run synchronously to clamp or release the hub.

[0038] The support shaft 5 is rotatably arranged on the side wall of the support plate 1, and a housing 12 is provided at the end of the support shaft 5. The upper inner wall and the lower inner wall of the housing 12 are respectively slidably connected with sliders 13. The two sliders 13 are connected by an alternating component 6. One side of the slider 13 close to the turntable 3 is connected with a rotating shaft 14. Two connecting mechanisms 8 are respectively installed on the corresponding rotating shafts 14, and the two connecting mechanisms 8 are respectively connected with the corresponding polishing wheels 18. Among them, the alternating component 6 is used to switch between the two polishing wheels 18, and the connecting mechanism 8 is used to connect the rotating shaft 14 and the polishing wheel 18.

[0039] It should be noted that the support shaft 5 is connected to an external driving mechanism. Among them, the external driving mechanism can be a motor. Through the motor, the support shaft 5 can be driven to rotate 180 degrees, thereby driving the housing 12 to flip 180 degrees.

[0040] Furthermore, polishing wheels 18 made of different materials are respectively provided on the two rotating shafts 14. The alternating component 6 can make one rotating shaft 14 extend out of the interior of the housing 12, and the other rotating shaft 14 be hidden inside the housing 12, so that different stages of polishing treatment can be carried out on the hub without replacing the polishing wheel 18, greatly improving the polishing speed of the hub.

[0041] In the embodiment of the present application, the connecting mechanism 8 can quickly connect or disassemble the rotating shaft 14 and the polishing wheel 18, so as to achieve the purpose of quickly replacing the polishing wheel 18, further improving the polishing efficiency for hubs that require polishing treatment more than twice.

[0042] The connecting mechanism 8 includes a connecting box 80, a locking component 81, a connecting column 82 and an unlocking component 83. Among them, the connecting box 80 is arranged on the rotating shaft 14, the locking component 81 is arranged inside the connecting box 80, one end of the connecting column 82 is connected to the center of the polishing wheel 18, the other end of the connecting column 82 is inserted into the interior of the connecting box 80, and a second accommodation cavity 822 is provided inside the connecting column 82. The unlocking component 83 is arranged in the second accommodation cavity 822.

[0043] It should be noted that one end of the connecting column 82 inserted into the interior of the connecting box 80 in this embodiment has a frustum structure, and the frustum structure makes it more convenient to push the connecting column 82 into the interior of the connecting box 80.

[0044] Furthermore, the locking assembly 81 can quickly fix the connecting column 82 and the connecting box 80 together, while the unlocking assembly 83 can quickly separate the connecting column 82 from the connecting box 80, so as to achieve the purpose of quickly installing and disassembling the polishing grinding wheel 18.

[0045] The second driving assembly 7 is arranged on the support plate 1 and is respectively connected to the two rotating shafts 14. Among them, the second driving assembly 7 is used to drive the rotating shaft 14 to rotate.

[0046] In the embodiment of the present application, the second driving assembly 7 can drive the rotating shaft 14 to rotate, so as to drive the polishing grinding wheel 18 to rotate, achieving the purpose of polishing the hub.

[0047] To further clarify the above embodiment, in an embodiment of the present application, as Figure 5 and Figure 6 shown, the locking assembly 81 includes two first connecting shafts 810, two first connecting rods 811, two locking columns 812 and a first spring 813. Among them, the two first connecting shafts 810 are symmetrically arranged on the inner wall of the connecting box 80, the two first connecting rods 811 are respectively rotatably connected to the corresponding first connecting shafts 810, a column groove 820 is provided through the connecting column 82, the two locking columns 812 are respectively arranged at the ends of the first connecting rods 811, and the two locking columns 812 are respectively inserted into the notch of the column groove 820, and both ends of the first spring 813 are connected to the two first connecting shafts 810.

[0048] It should be noted that the first connecting rod 811 described in this embodiment is in a "Z" shape, and the end of the locking column 812 is a hemispherical structure. When the first spring 813 is in a natural state, the distance between the two locking columns 812 is less than the diameter of the connecting column 82 but greater than the minimum diameter of the frustum. When the connecting column 82 is pushed into the interior of the connecting box 80, the arc surface of the frustum first contacts the hemisphere of the locking column 812. Continuing to push the connecting column 82, the frustum squeezes the two locking columns 812 to expand outwards, and the first spring 813 is squeezed and deformed. When the two locking columns 812 move into the column groove 820, the connecting box 80 and the connecting column 82 can be fixed.

[0049] Furthermore, as Figure 5 and Figure 6As shown in the figure, the unlocking component 83 includes two ejector posts 830, two second link rods 831, a second connecting shaft 832, a push plate 833 and a second spring 834. Among them, the two ejector posts 830 are symmetrically arranged inside the post groove 820. The inner wall of the second accommodation cavity 822 is provided with a first sliding groove 823. The second connecting shaft 832 is slidably connected to the first sliding groove 823. The two ends of the second link rod 831 are respectively hinged to the ejector post 830 and the second connecting shaft 832. The connecting post 82 is provided with a second sliding groove 821. The push plate 833 is slidably connected to the second sliding groove 821, and the push plate 833 is arranged on the second connecting shaft 832. The two ends of the second spring 834 are respectively connected to the push plate 833 and the inner wall of the second sliding groove 821.

[0050] It should be noted that one end of the ejector post 830 close to the notch of the post groove 820 is of a hemispherical structure, and the two ejector posts 830 are located between the two locking posts 812. The second sliding groove 821 is communicated with the second accommodation cavity 822. The first sliding groove 823 is arranged along the axial direction of the connecting post 82. When the second spring 834 is in a natural state, under the action of the push plate 833 and the second link rod 831, the two ejector posts 830 are hidden inside the post groove 820 and do not contact the locking posts 812.

[0051] Specifically, when replacing the polishing grinding wheel 18, the relevant personnel press the push plate 833, and the push plate 833 squeezes the second spring 834 to deform. At this time, the push plate 833 moves in the direction of the second spring 834. Refer to Figure 5 As shown in the figure, it drives the second connecting shaft 832 to move leftward. With the cooperation of the second link rod 831, the two ejector posts 830 are pushed to move upward and downward respectively, so as to push the two locking posts 812 out of the post groove 820. At this time, pull the connecting post 82 to the right, and the connecting post 82 can be separated from the connecting box 80, achieving the purpose of quickly disassembling the polishing grinding wheel 18.

[0052] In an embodiment of the present application, as Figure 5 and Figure 6 shown, the outer wall of the connecting post 82 is provided with a circular ring 15. One side of the circular ring 15 facing the connecting box 80 is provided with a plurality of limiting blocks 16. The connecting box 80 is provided with a plurality of limiting grooves 17. The plurality of limiting blocks 16 are respectively arranged in the corresponding limiting grooves 17. The connecting post 82 can be further limited by the limiting blocks 16 and the limiting grooves 17, improving the stability of the connecting post 82 when rotating.

[0053] In an embodiment of the present application, as Figure 3As shown in the figure, the first driving assembly 9 includes a driving member 90, a first toothed plate 91, and a first gear 92. Among them, the driving member 90 is installed inside the first accommodating cavity 30, the first toothed plate 91 is arranged at the output end of the driving member 90, the first gear 92 is rotatably arranged inside the first accommodating cavity 30, and the first gear 92 is meshed and connected with the first toothed plate 91.

[0054] It should be noted that the driving member 90 can be an electric push rod or a pneumatic rod. Through the driving member 90, the first toothed plate 91 can be driven to move, and the first toothed plate 91 drives the first gear 92 to rotate, so as to synchronously control a plurality of clamping assemblies 4.

[0055] Furthermore, as Figure 3 shown in the figure, the clamping assembly 4 includes a connecting plate 40, a sliding plate 41, and a clamping plate 42. Among them, a cover plate 11 is provided on the first accommodating cavity 30, and a plurality of third sliding grooves 110 are provided through the cover plate 11. The sliding plate 41 is slidably connected with the third sliding grooves 110. The two ends of the connecting plate 40 are respectively hinged to the sliding plate 41 and the first gear 92, and the clamping plate 42 is arranged on the connecting plate 40.

[0056] It should be noted that the connecting plate 40 described in this embodiment is an L-shaped structure. When the first gear 92 rotates, the position of the end point of the connecting plate 40 can be changed and restricted by the third sliding grooves 110 and the sliding plate 41, so that a plurality of clamping plates 42 approach or move away synchronously, achieving the purpose of clamping or releasing the hub.

[0057] In an embodiment of the present application, as Figure 2 shown in the figure, the alternating assembly 6 includes a second gear 60 and two second toothed plates 61. Among them, the second gear 60 is rotatably arranged inside the housing 12, the two second toothed plates 61 are respectively arranged on the corresponding sliders 13, and the two second toothed plates 61 are respectively meshed and connected with the second gear 60.

[0058] In the embodiment of the present application, the second gear 60 is connected to an external motor. Through the external motor, the second gear 60 can be driven to rotate, and the two sliders 13 can be driven to move in the opposite direction through the mutual cooperation of the two second toothed plates 61, so that the corresponding polishing wheels 18 move towards the hub.

[0059] In an embodiment of the present application, as Figure 2 shown in the figure, the second driving assembly 7 includes a motor 70, a third gear 71, and two fourth gears 72. Among them, the motor 70 is installed on the support plate 1, the third gear 71 is arranged at the output end of the motor 70, the two fourth gears 72 are respectively arranged on the corresponding rotating shafts 14, and the fourth gear 72 forms a meshing relationship with the third gear 71.

[0060] It should be noted that the motor 70 described in this embodiment is a non-self-locking motor, that is, the motor 70 does not have a self-locking function. After the power supply of the motor 70 is cut off, the rotor can be driven to rotate by an external force.

[0061] In the embodiment of the present application, when the support shaft 5 drives the housing 12 to flip 180 degrees, the fourth gear 72 rotates to mesh with the third gear 71. At this time, the motor 70 can drive the third gear 71 to rotate, and drive the rotating shaft 14 to rotate through the cooperation of the fourth gear 72, so as to drive the polishing grinding wheel 18 to rotate.

[0062] Specifically, during the process of polishing the hub, the relevant personnel place the hub between a plurality of clamping plates 42 and control the driving member 90 to start. The driving member 90 drives the first toothed plate 91 to move. With the cooperation of the first gear 92 and the connecting plate 40, a plurality of sliding plates 41 and clamping plates 42 move towards the center of the turntable 3 to fix the hub to the turntable 3.

[0063] Then the relevant personnel can control the sliding table module 10 to start and drive the vertical plate 2 to approach the polishing grinding wheel 18. By driving the rotating shaft 14 to rotate, the polishing grinding wheel 18 is driven to rotate. At the same time, the relevant personnel control the turntable 3 to rotate, see Figure 2 , and use the lower polishing grinding wheel 18 to perform the first polishing treatment on the inner wall of the hub.

[0064] After the first polishing treatment is completed, it is necessary to switch the upper and lower polishing grinding wheels 18. At this time, the relevant personnel control the second gear 60 to rotate. The second gear 60 drives the two second toothed plates 61 to move in opposite directions, see Figure 2 , the lower polishing grinding wheel 18 moves towards the housing 12, and the upper polishing grinding wheel 18 moves towards the hub. Subsequently, the relevant personnel control the support shaft 5 to rotate 180 degrees. The support shaft 5 drives the housing 12 to flip 180 degrees to exchange the positions of the two polishing grinding wheels 18. When the fourth gear 72 rotates to mesh with the third gear 71, the rotating shaft 14 can be driven to rotate through the second driving component 7.

[0065] When the hub needs to be polished multiple times or the polishing grinding wheel 18 needs to be replaced, see Figure 5 and Figure 6 , the relevant personnel press the push plate 833 to the left. The second spring 834 is compressed and drives the second connecting shaft 832 to move to the left. Through the cooperation of the second connecting rod 831, the two ejector posts 830 move upward and downward respectively to eject the locking post 812 from the post groove 820. Finally, drag the connecting post 82 to the right, and the connecting post 82 can be quickly separated from the connecting box 80. Similarly, when the push plate 833 is released, the second spring 834 drives the push plate 833 to reset, and with the cooperation of the second connecting rod 831, the two ejector posts 830 are hidden in the post groove 820

[0066] When installing the connecting column 82, insert the connecting column 82 to the left between the two locking columns 812. The locking columns 812 move upward and downward along the inclined surface of the frustum respectively until the locking columns 812 move into the column groove 820, then the connecting column 82 can be fixed to the connecting box 80. Meanwhile, with the cooperation of the limiting block 16 and the limiting groove 17, the fixing effect is further improved, so that the polishing grinding wheel 18 can be installed and disassembled quickly, saving the time for replacing the polishing grinding wheel 18 and improving the polishing efficiency.

[0067] In summary, the electric vehicle hub polishing device of the embodiment of the present application can quickly switch between two polishing grinding wheels, significantly improving the polishing efficiency. At the same time, the connection mechanism makes the installation and disassembly process of the polishing grinding wheel extremely simple and fast, further improving the efficiency of the overall polishing process.
