[0022] Embodiment 1

[0023] The surface treatment device for an integrated aluminum alloy wheel hub, referring to Figures 1 - 7 as shown, includes a mounting base 1; It further includes a moving unit, an electric turntable 2, a support frame 3, a rotating unit, an arc plate 4, a grinding block 5 and a fixing component; the mounting base 1 is connected with the moving unit; the moving unit is connected with the electric turntable 2; the rotating part of the electric turntable 2 is fixedly connected with the support frame 3; the support frame 3 is connected with the rotating unit; the rotating unit is connected with two arc plates 4; one grinding block 5 is fixedly connected to the left side and the right side of each arc plate 4 respectively. After the two grinding blocks 5 on the same side rotate and contact, the curve contour of the side surface away from the arc plate 4 is consistent with the curve contour of the surface of the wheel hub 100; the moving unit is connected with two fixing components.

[0025] The grinding block 5 is set to protrude from the inner side surface of the arc-shaped plate 4, and the side surface of the hub 100 can also be ground through the grinding block 5.

[0026] A rubber gasket is arranged on the surface of the supporting plate 9 to prevent damage to the hub 100 when supporting and fixing the hub 100.

[0027] The moving unit includes an electric guide rail 01, an electric slider one 02 and an electric slider two 03; two electric guide rails 01 are bolted to the mounting base 1; each electric guide rail 01 is slidably connected with an electric slider one 02, and the two electric sliders one 02 are jointly fixedly connected with the electric turntable 2; each electric guide rail 01 is slidably connected with two electric sliders two 03, and every two front and rear corresponding electric sliders two 03 are fixedly connected with a mounting plate 10.

[0028] The rotating unit includes a rotating rod 41, a rotating gear 42 and a rotating motor 43; the support frame 3 is fixedly connected with the rotating motor 43; the support frame 3 is rotatably connected with two rotating rods 41, and each rotating rod 41 is respectively fixedly connected with an arc-shaped plate 4; two rotating gears 42 are fixedly connected to each rotating rod 41, the rotating gears 42 on the two rotating rods 41 are meshed with each other, and the output shaft of the rotating motor 43 is fixedly connected with one of the rotating rods 41.

[0029] The rotating unit includes an AC motor 101, a linkage gear one 102 and a linkage gear two 103; the mounting plate 10 is fixedly connected with the AC motor 101; the output shaft of the AC motor 101 is fixedly connected with the linkage gear one 102; the rotating disc 6 is fixedly connected with the linkage gear two 103, and the linkage gear two 103 is meshed with the linkage gear one 102.

[0030] Before the surface of the hub 100 is polished, the hub 100 is first placed on two arc-shaped plates 4 by an external manipulator. At this time, the inner side of the placed hub 100 faces the left mounting plate 10, as Figure 1As shown, then control the electric slider 02 to drive the electric turntable 2, the support frame 3, the arc plate 4, and other connected parts to move leftward along the electric guide rail 01. During the movement, control the micro electric push rod 104 on the left mounting plate 10 to drive the movable plate 105 to move away from the mounting plate 10. The movable plate 105 drives the rotating shaft 7 through the fixing part 71. Since the support plate 9 is restricted by the rotating disc 6, the connecting plate 8 and the support plate 9 cannot move leftward synchronously with the rotating shaft 7. Therefore, when the rotating shaft 7 drives the rotating end connected to the rotating shaft 7 on the connecting plate 8 to move leftward together, the connecting plate 8 rotates, thereby pulling the support plate 9 to slide on the rotating disc 6. At this time, the support plate 9 slides toward the rotating shaft 7, causing the support plate 9 on the rotating disc 6 to approach and converge. As the electric slider 02 continuously drives the hub 100 to move, the converged support plate 9 enters the interior of the hub 100. When the hub 100 abuts against the limiting part 91 of all the support plates 9, control the electric slider 02 to stop moving. Then control the micro electric push rod 104 to drive the movable plate 105 to move toward the mounting plate 10. The movable plate 105 drives the rotating shaft 7 to move, and the rotating shaft 7 drives the support plate 9 to slide away from the center of the rotating disc 6, causing the support plates 9 on the rotating disc 6 to move away from each other. Thus, the hub 100 placed on the two arc plates 4 is supported and fixed by the movement of the support plates 9; then control the rotating motor 43 to drive the rotating rod 41 to rotate. Under the action of the gear, the two arc plates 4 rotate away from each other, and the two arc plates 4 expand outward, causing the two arc plates 4 to separate from the hub 100. Then control the electric slider 02 to drive the electric turntable 2, the support frame 3, and the arc plate 4 to reset. During the process of the electric slider 02 driving the arc plate 4 to reset, since the arc plate 4 drives the grinding block 5 to expand outward, the grinding block 5 will not collide and interfere with the hub 100. Subsequently, control the rotating motor 43 to continue driving the two arc plates 4 to rotate and reset; when the electric turntable 2 and the arc plate 4 are both reset, then the second hub 100 is placed on the two arc plates 4 by an external manipulator. After the placement is completed, control the electric slider 02 to drive the electric turntable 2, the support frame 3, the arc plate 4, and the placed hub 100 to move rightward along the electric guide rail 01. At this time, since the inner side of the hub 100 faces away from the right mounting plate 10, when the electric slider 02 moves, control the electric turntable 2 to drive the support frame 3, the arc plate 4, and the placed hub 100 to rotate 180 degrees, so that the inner side of the hub 100 is aligned with the rotating disc 6 on the right. As the electric slider 02 continuously moves rightward, perform the same operation as above to control the support plate 9 on the right to support and fix the second hub 100; through the above work, the hub 100 is placed on the arc plate 4, and the two hubs 100 are automatically fixed by the movement of the arc plate 4. Compared with manually placing and fixing the hub 100, the overall efficiency can be improved and the labor cost can be reduced.

[0031] After the two wheel hubs 100 are fixed, the two arc plates 4 are located between the two mounting plates 10. Then the rotating motor 43 is controlled to drive the two arc plates 4 to rotate toward each other, so that the two arc plates 4 rotate closer to each other. When the grinding blocks 5 on the two arc plates 4 contact each other, the rotating motor 43 is controlled to stop rotating. Then the left electric slider 203 is controlled to drive the left support plate 9 and the mounting plate 10, as well as the supported and fixed wheel hub 100 to move toward the arc plate 4, and the right electric slider 203 is synchronously controlled to drive the right support plate 9 and the mounting plate 10, as well as the supported and fixed wheel hub 100 to move toward the arc plate 4. Figure 6 As shown, when the surface of the wheel hub 100 touches the grinding block 5, it stops moving. At this time, the side of the grinding block 5 that is consistent with the surface curve of the wheel hub 100 directly fits the surface of the wheel hub 100, and then the AC motor 101 is controlled to drive the linkage gear 1 102 to rotate, the linkage gear 1 102 drives the linkage gear 2 103 to rotate, the linkage gear 2 103 drives the rotating disk 6, the rotating shaft 7, the connecting plate 8 and the supporting plate 9, and the support plate 9 supports the fixed wheel hub 100 to rotate, so that the surface of the wheel hub 100 is polished by the grinding block 5, and the two wheel hubs 100 can be polished at the same time by the grinding block 5, thereby improving the polishing efficiency.

[0032] Furthermore, after the grinding blocks 5 have finished grinding the surfaces of the two wheel hubs 100, the rotating motor 43 is controlled to drive the two arc plates 4 to rotate in opposite directions, so that the two arc plates 4 drive the grinding blocks 5 to rotate and spread out, so that the grinding blocks 5 are staggered with the outer contour of the wheel hub 100, and then the left and right electric sliders 203 are controlled to simultaneously drive the support plates 9, and the support plates 9 support the fixed wheel hubs 100 to move toward each other, and the movement is stopped when the surfaces of the two wheel hubs 100 contact each other, as shown in FIG. Figure 7 As shown, the rotating motor 43 is then controlled to drive the two arc plates 4 to rotate toward each other. Since the thickness of the grinding block 5 is greater than that of the arc plates 4, as the two arc plates 4 continue to rotate toward each other, the grinding block 5 on the arc plates 4 contacts the side of the wheel hub 100. At this time, the AC motors 101 on both sides are synchronously controlled to drive the corresponding support plates 9 and the wheel hub 100 to rotate in the same direction, so as to grind the side of the wheel hub 100. In addition, during the grinding process, the electric sliders 203 on both sides are synchronously controlled to drive the corresponding support plates 9 and the wheel hub 100 to move back and forth left and right, so that the grinding block 5 can fully grind all parts of the side of the wheel hub 100.

[0033] Thus, during the process of grinding the surface of the hub 100, the arc-shaped plate 4 is used to achieve automatic feeding of the hub 100, eliminating the need for manual operation, improving the overall efficiency, and reducing labor costs. After the surface of the hub 100 is ground by the grinding blocks 5 on the arc-shaped plate 4, by controlling the rotation and change of the arc-shaped plate 4 to drive the grinding blocks 5, the grinding blocks 5 can also grind the side parts of the hub 100. Compared with the existing method of moving the hub 100 to different devices for grinding, the processing efficiency of the hub 100 is effectively improved.

[0034] Embodiment 2

[0035] Based on Embodiment 1, with reference to Figures 7 - 11 As shown, it further includes an electromagnet 201, an elastic member 202, a metal strip 203, and a grinding strip 204; each support plate 9 is provided with three storage grooves 901; one electromagnet 201 is fixedly connected in each storage groove 901; several elastic members 202 are fixedly connected to each electromagnet 201, and the elastic members 202 are spring rods; all the elastic members 202 in the same storage groove 901 are commonly fixedly connected to a metal strip 203; a grinding strip 204 is fixedly connected to one side of each metal strip 203 away from the elastic member 202, and the inner part of the hub 100 is ground by the grinding strip 204.

[0036] It further includes a fixing frame 111, a first electric push rod 112, a fixing plate 113, a bottom plate 114, a pressing plate 115, and a bidirectional electric push rod 116; the mounting base 1 is fixedly connected to the fixing frame 111; two first electric push rods 112 are fixedly connected to the fixing frame 111; the telescopic parts of all the first electric push rods 112 are commonly fixedly connected to a fixing plate 113; the fixing plate 113 is elastically connected to the bottom plate 114 through a spring rod; the bottom plate 114 is slidably connected to two pressing plates 115 through a slide rail; two bidirectional electric push rods 116 are fixedly connected to the bottom plate 114, and the two telescopic parts of each bidirectional electric push rod 116 are respectively fixedly connected to one of the pressing plates 115.

[0037] It further includes a second electric push rod 117 and a support block 118; each arc-shaped plate 4 is provided with two through grooves; several second electric push rods 117 are fixedly connected to the rotating part of the electric turntable 2; a support block 118 is fixedly connected to the telescopic part of each second electric push rod 117, and the support block 118 is located at the through groove of the arc-shaped plate 4.

[0038] A notch 11501 is formed in the middle of the pressing plate 115. When the two arc-shaped plates 4 rotate and merge to grind the surface of the hub 100, by clamping the two arc-shaped plates 4 at the notch 11501, the rotated two arc-shaped plates 4 are fixed, thereby improving the stability during the grinding of the surface of the hub 100.

[0039] The lower side surface of the pressing plate 115 and the upper side surface of the support block 118 are both set to be arc-shaped that fits the side surface of the wheel hub 100, which can fit the side surface of the wheel hub 100 and improve the stability of clamping and fixing the wheel hub 100.

[0040] A surface treatment method for an integrated aluminum alloy wheel hub includes the following steps: Step 1: Place the wheel hub 100 on two arc-shaped plates 4 through an external manipulator, and fix the wheel hub 100 on the support plate 9 by moving the arc-shaped plates 4; Step 2: Control the movement of the support plate 9 and the wheel hub 100 fixed by the support plate 9, so that the surface of the wheel hub 100 touches the grinding block 5. Drive the wheel hub 100 to rotate through the support plate 9 to perform grinding treatment on the surface of the wheel hub 100; Step 3: Control the movement of the support plate 9 and the wheel hub 100 fixed by the support plate 9, so that the surfaces of the two wheel hubs 100 are in contact with each other, and control the grinding block 5 on the arc-shaped plate 4 to contact the side surface of the wheel hub 100. Then drive the wheel hub 100 to rotate through the support plate 9 to perform grinding treatment on the side surface of the wheel hub 100; Step 4: Control the pressing plate 115 and the support block 118 to move towards each other to clamp and fix the two wheel hubs 100, and control the support plate 9 to move away from the wheel hub 100. Then control the pressing plate 115 to drive the upper part of the wheel hub 100 to move together to pour out the debris inside the wheel hub 100; Step 5: Control the electromagnet 201 to cut off the power supply to stop magnetically attracting the metal strip 203, so that the grinding strip 204 pops out of the storage groove 901. Then control the support plate 9 to move into the interior of the wheel hub 100, and control the movement of the support plate 9 so that the grinding strip 204 contacts the inner side of the wheel hub 100. Then drive the support plate 9 and the grinding strip 204 to rotate to grind the inner side of the wheel hub 100; Step 6: Control the external manipulator to remove the wheel hub 100, and manually use a grinding machine to grind the groove and through-hole parts of the wheel hub 100 to complete the grinding treatment of each part of the wheel hub 100.

[0041] On the basis of the above-mentioned Embodiment 1, after the grinding treatment of the surface and side of the wheel hub 100 is completed, it is also necessary to perform grinding treatment on its inner side, so as to fully grind each surface of the wheel hub 100. However, during the grinding treatment of the surface of the wheel hub 100, the grinding debris will fall into the interior of the wheel hub 100 through the through holes on the surface. The fallen debris not only hinders the grinding of the inner side of the wheel hub 100, but also affects its overall grinding efficiency. Therefore, when the grinding treatment of the surface and side of the wheel hub 100 is completed, then control the electric push rod 112 to drive the fixing plate 113, the bottom plate 114 and the pressing plate 115 to move downward. The pressing plate 115 moves downward to contact the wheel hub 100. And during the movement of the pressing plate 115, at the same time, control the electric push rod 117 to drive the support block 118 to move upward. The support block 118 moves upward to contact the wheel hub 100. Then synchronously control the pressing plate 115 and the support block 118 to move towards each other to clamp and fix the two wheel hubs 100. Then control the support plate 9 on the rotating disc 6 to move and fold up to stop supporting and fixing the wheel hub 100, and then control the electric slider 03 to drive the support plate 9 to move away from the wheel hub 100. At this time, as Figure 9 shown, by moving the pressing plate 115 and the support block 118 towards each other, the two wheel hubs 100 are clamped and fixed, and at the same time, control the rotation motor 43 to drive the two arc-shaped plates 4 to rotate away from each other to avoid the clamped and fixed wheel hub 100. Then control the bidirectional electric push rod 116 to drive the two pressing plates 115 to slide away from each other along the slide rails on the bottom plate 114. The pressing plate 115 drives the upper part of the clamped wheel hub 100 to move together, so that the wheel hub 100 is changed to an inclined state, so as to pour out the debris falling into the inner side of the wheel hub 100. And by controlling the electric push rod 117 to drive the support block 118 to move up and down quickly, the support block 118 drives the wheel hub 100, the pressing plate 115 and the bottom plate 114 to perform lifting motion. Under the action of the spring rod on the bottom plate 114, drive the wheel hub 100 to shake up and down to fully pour out and clean the debris, so as to facilitate the subsequent grinding treatment of the inner side of the wheel hub 100.

[0042] When considering the existing grinding process for the hub 100, usually multiple devices are used to grind different surfaces of the hub 100. This method not only requires multiple loading and unloading operations of the hub 100, which is cumbersome, but also has a low overall grinding efficiency. Therefore, after the debris in the hub 100 is shaken out by moving the pressing plate 115, then control the bidirectional electric push rod 116 to drive the pressing plate 115 to move back to its original position, so that the two hubs 100 return to the vertical state again. Then control the electric push rod 112 to drive the pressing plate 115 to descend, synchronously control the electric push rod 117 to drive the support block 118 to descend, and then control the rotation motor 43 to drive the two arc-shaped plates 4 to rotate towards each other and contact the hub 100. Through the cooperation of the pressing plate 115 and the arc-shaped plates 4, the hub 100 is clamped and fixed. Then the control system stops supplying power to the electromagnet 201, so that the electromagnet 201 stops magnetically attracting the metal strip 203. After the metal strip 203 loses magnetic attraction, under the action of the elastic member 202, the grinding strip 204 is pushed out of the storage groove 901. Then control the electric slider 03 to drive the support plate 9 and the mounting plate 10 to move closer to the hub 100 again. When the support plate 9 moves into the interior of the hub 100, stop moving. Then control the support plate 9 to slide towards the inner side of the hub 100, so that the grinding strip 204 on the support plate 9 contacts the inner side of the hub 100. Then control the AC motor 101 to drive the support plate 9 and the grinding strip 204 to rotate, and grind the inner side of the hub 100. The grinding strip 204 on the support plate 9 can grind the inner side of the hub 100, cooperate with the grinding block 5 to grind the surface and side of the hub 100, and fully grind each surface of the hub 100 to improve the overall processing efficiency. It should be noted that initially, the electromagnet 201 is in the energized state, the electromagnet 201 generates magnetic attraction on the metal strip 203, and the metal strip 203 drives the grinding strip 204 to move into the storage groove 901 under the action of magnetic attraction, and the elastic member 202 is in a compressed state.

[0043] When the grinding of each surface of the two hubs 100 is completed, the peripherally provided manipulator is used to remove the ground hub 100, and then the control system is used to energize the electromagnet 201 again. The electromagnet 201 is energized to generate magnetic attraction on the metal strip 203, and the metal strip 203 and the grinding strip 204 are moved into the storage groove 901, so that the elastic member 202 is in a compressed state, which is convenient for the support plate 9 to support and fix the subsequent hub 100 to be processed. Subsequently, the operator uses equipment such as a grinding machine to grind the groove and through-hole parts of the removed hub 100, so as to complete the grinding of each part of the hub 100.

[0044] Moreover, a notch 11501 is formed in the middle of the pressing plate 115. When polishing the surface of the hub 100, when the two arc-shaped plates 4 rotate towards each other and the polishing blocks 5 on the two arc-shaped plates 4 come into contact with each other, then control the first electric push rod 112 to drive the pressing plate 115 to move downward. The downward movement of the pressing plate 115 clamps the two rotated arc-shaped plates 4 at the notch 11501, as Figure 10 shown, so as to fix the two rotated arc-shaped plates 4. By fixing the two rotated arc-shaped plates 4 with the pressing plate 115, the stability of the arc-shaped plates 4 and the polishing blocks 5 can be improved when polishing the surface of the hub 100, and the shaking and deviation of the arc-shaped plates 4 and the polishing blocks 5 during the polishing process can be avoided, which affects the overall polishing accuracy.
