Specific embodiments
[0022] The technical solutions of the present utility model will be further described below with reference to the accompanying drawings.
[0023] Embodiment 1: A surface treatment processing device for manufacturing automobile wheels, as shown in Figure 1 、 Figure 2 and Figure 4 , includes a workbench 1. The workbench 1 is provided with two working planes, front and back. The rotary plate 2 is rotatably connected to the workbench 1 through the rotating shaft 3. The rotating shaft 3 penetrates through the middle of the workbench 1. The rotary plate 2 is fixedly installed with a rotating motor 4. The output shaft of the rotating motor 4 is connected to the rotating disc 5. The rotating disc 5 is located on the rotary plate 2. The rotary plate 2 is located between the rotating disc 5 and the rotating motor 4. The threaded rod 7 is rotatably connected to the middle of the rotating disc 5. A nut is provided at the top of the threaded rod 7. A plurality of guide rods 6 are fixedly connected to the rotating disc 5. The guide rods 6 are evenly distributed around the threaded rod 7. The sliding round table 71 is threadedly connected to the threaded rod 7. The sliding round table 71 is slidably sleeved on the guide rod 6. The top surface diameter of the sliding round table 71 is larger than its bottom surface diameter. At least three chutes 51 are circumferentially provided at the top of the rotating disc 5. The fixture fixing block 8 is slidably connected to the rotating disc 5 through the chute 51. A return spring 83 is connected between the fixture fixing block 8 and the rotating disc 5. The return spring 83 is located in the chute 51 and close to the sliding round table 71. The fixture fixing blocks 8 are evenly distributed around the sliding round table 71. The fixture fixing block 8 is connected with a roller 81. The roller 81 can slide on the side surface of the sliding round table 71. A rubber pad 82 is provided at one end of the fixture fixing block 8 away from the roller 81. The sliding frame 9 is slidably penetrated through the upper left of the rear working plane of the workbench 1. The middle of the right end of the sliding frame 9 is provided with a first grinding piece 91. The shape of the first grinding piece 91 matches the outer surface of the wheel hub. The first grinding piece 91 is detachable and replaceable. The second grinding pieces 92 are symmetrically and slidably connected to the right end of the sliding frame 9. A compression spring 93 is connected between the second grinding pieces 92 and the sliding frame 9. The two second grinding pieces 92 are respectively located at the front and rear ends of the first grinding piece 91. Replaceable grinding blocks are provided on the second grinding pieces 92.
[0024] In the initial state, the rotary plate 2 is located on the front working plane of the workbench 1. The fixture fixing block 8 is close to the sliding turntable 71, and the roller 81 is close to the side surface of the sliding turntable 71. When the surface of the hub needs to be polished, the surface of the hub with spokes is facing up, and the mounting hole in the middle of the hub is aligned with the threaded rod 7. A wrench is put on the nut at the top of the threaded rod 7, and the wrench is rotated to drive the threaded rod 7 to rotate. The rotation of the threaded rod 7 drives the sliding turntable 71 to move downward. The sliding turntable 71 squeezes the roller 81 away from the center of the rotating disc 5 through its outer inclined surface, thereby driving the fixture fixing block 8 to slide in the chute 51, and the return spring 83 is stretched accordingly. The fixture fixing block 8 gradually approaches the inner wall of the hub, and finally multiple fixture fixing blocks 8 jointly support and fix the inside of the hub. The elastic force of the rubber pad 82 can increase the friction between the hub and the fixture fixing block 8, improve the stability of the support system, and ensure the quality of the hub at the same time. The rotating shaft 3 is rotated to make the rotary plate 2 rotate 90 degrees. At this time, the rotary plate 2 is perpendicular to the working plane of the workbench 1, and the hub is located above the rear working plane of the workbench 1. The rotating motor 4 is started to drive the hub to rotate continuously. The sliding frame 9 is pushed to make the first grinding member 91 close to the surface of the hub, so that the first grinding member 91 grinds and processes the surface of the hub, and the second grinding member 92 grinds the rim part of the hub. The compression spring 93 enables the second grinding member 92 to automatically adapt to the size of the hub, improving the processing efficiency. After grinding, the sliding frame 9 is pulled to make the first grinding member 91 away from the surface of the hub, the rotating motor 4 is turned off to stop the rotation of the hub, the rotating shaft 3 is rotated to make the rotary plate 2 return to the front working plane of the workbench 1, a wrench is put on the nut at the top of the threaded rod 7, so that the sliding turntable 71 moves upward and away from the roller 81, the return spring 83 is reset accordingly, and the fixture fixing block 8 slides and moves away from the inner wall of the hub, thereby releasing the fixation of the hub, facilitating the retrieval and replacement of the hub for the next grinding, and improving the work efficiency.
[0025] As Figure 3 shown, a cylinder 10 is fixedly installed at the rear end of the workbench 1, and a T-shaped guide rail is fixedly installed on the workbench 1. The T-shaped guide rail is located in front of the cylinder 10. A fixing block is sleeved on the piston rod of the cylinder 10, and the fixing block is slidably sleeved on the T-shaped guide rail. A pull rod is fixedly connected to the end of the piston rod of the cylinder 10. The left end of the rotating shaft 3 is fixedly connected with a transmission conversion plate 11. A fillet rectangular through hole is formed in the transmission conversion plate 11, and the pull rod slidably passes through the fillet rectangular through hole, so that the cylinder 10 is connected with the transmission conversion plate 11. The rotation angle of the transmission conversion plate 11 is 0-90°.
[0026] When the rotary plate 2 needs to be rotated, the cylinder 10 is started to extend or shorten to drive the transmission conversion plate 11 to rotate, and then the rotary plate 2 is driven to rotate 90 degrees through the rotating shaft 3, reducing manual operation.
[0027] As Figure 5As shown in the figure, a ring-shaped support frame 12 for supporting the hub is slidably penetrated through the rotary plate 2. The ring-shaped support frame 12 is provided with a support ring and a plurality of support rods. The support ring is located on one side of the rotary plate 2 close to the rotary motor 4. A circular space for the movement of the rotary motor 4 is opened on the working plane at the front of the workbench 1. The diameter of the support ring of the ring-shaped support frame 12 is larger than the diameter of the circular space. A limit ring is provided on the outer side of the top end of the support rod.
[0028] In the initial state, the support ring of the ring-shaped support frame 12 is close to the workbench 1. The support rods of the ring-shaped support frame 12 pass through the rotary plate 2 and are distributed around the fixture fixing block 8 in a surrounding manner. When the hub is placed above the rotary plate 2, the ring-shaped support frame 12 can support the hub. When the rotary plate 2 rotates 90 degrees, the ring-shaped support frame 12 is pulled forward, and the limit ring can prevent the ring-shaped support frame 12 from detaching from the rotary plate 2.
[0029] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
