Technical Field
[0001] This utility model belongs to the field of automotive wheel hub testing technology, specifically relating to an automotive wheel hub smoothness testing device. Background Technology
[0002] The smoothness of automotive wheel rims is a crucial factor affecting vehicle safety and stability. During the wheel rim manufacturing process, rigorous smoothness testing is required. Existing wheel rim smoothness testing equipment typically operates at a single station. During testing, the current wheel rim must be inspected before the next one can be loaded or unloaded, resulting in low testing efficiency and failing to meet the demands of large-scale production.

A U-shaped plate is fixedly connected to the upper surface of the base plate. Second mounting seats are fixedly connected to both the front and rear sides of the inner wall of the U-shaped plate. A second servo motor is fixedly connected to the upper surface of the second mounting seat. A second rotating shaft is fixedly connected to the output end of the second servo motor. A rubber roller is fixedly bonded to the surface of the second rotating shaft. An electric push rod is fixedly connected to the top of the inner wall of the U-shaped plate.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0024] like Figures 1 to 8As shown, a vehicle wheel hub smoothness testing device includes a base plate 1. A first mounting base 2 is fixedly connected to the upper surface of the base plate 1. A first servo motor 3 is fixedly connected to the upper surface of the first mounting base 2. A first rotating shaft 4 is fixedly connected to the output end of the first servo motor 3. A first bearing 5 is fixedly connected to the surface of the first rotating shaft 4. A first support plate 6 is fixedly connected to the outer ring of the first bearing 5. Columns 7 are fixedly connected to the bottom of the first support plate 6 and the upper surface of the base plate 1. A connecting plate 8 is fixedly connected to the surface of the first rotating shaft 4. Support rings 9 are fixedly connected to both the front and rear sides of the connecting plate 8. Second support plates 10 are fixedly connected to both the front and rear sides of the inner wall of the support rings 9. The inner wall of the second support plate 10 is fixedly connected to... A second bearing 11 is fixedly connected to the base plate 1. A cylinder 12 is fixedly connected to the inner ring of the second bearing 11. A disc 13 is fixedly connected to the surface of the cylinder 12. A U-shaped plate 14 is fixedly connected to the upper surface of the base plate 1. A second mounting seat 15 is fixedly connected to both the front and rear sides of the inner wall of the U-shaped plate 14. A second servo motor 16 is fixedly connected to the upper surface of the second mounting seat 15. A second rotating shaft 17 is fixedly connected to the output end of the second servo motor 16. A rubber roller 18 is fixedly bonded to the surface of the second rotating shaft 17. An electric push rod 19 is fixedly connected to the top of the inner wall of the U-shaped plate 14. A third mounting seat 20 is fixedly connected to the bottom end of the electric push rod 19. A laser scanner 21 is fixedly connected to the bottom of the third mounting seat 20.
[0025] Among them, the axis of the support ring 9 coincides with the axis of the first rotating shaft 4, and there are two disks 13, which are symmetrically distributed with the first rotating shaft 4 as the center.
[0026] It should be noted that by setting two discs 13 on the support ring 9, and by having the first servo motor 3 drive the two discs 13 to rotate around the first rotating shaft 4, when the detection device detects the wheel hub on the left disc 13, the worker can replace the car wheel hub that has been detected on the right disc 13. The second servo motor 16 can drive the rubber roller 18 to rotate, and when the left disc 13 contacts the rubber roller 18, the friction between the disc 13 and the rubber roller 18 can cause the rotating rubber roller 18 to drive the disc 13 to rotate. The electric push rod 19 can control the laser scanner 21 to move up or down. The laser scanner 21 can scan the surface of the wheel hub and determine the smoothness of the wheel hub based on the scanning results.
[0027] like Figures 1 to 9As shown, a rectangular hole 22 is provided inside the disc 13. A rectangular plate 23 is fixedly connected to the inner wall of the rectangular hole 22. A rectangular cylinder 24 is fitted on the surface of the rectangular plate 23. A circular hole 25 is provided on the upper surface of the rectangular cylinder 24. A threaded cylinder 26 is fixedly connected to the inner wall of the circular hole 25. A threaded post 27 is threadedly connected to the inner wall of the threaded cylinder 26. The bottom of the threaded post 27 is in contact with the surface of the rectangular plate 23. A hollow positioning post 28 is fixedly connected to the surface of the threaded post 27.
[0028] Among them, a rotating block 29 is fixedly connected to the surface of the threaded column 27. The rotating block 29 is located above the hollow positioning column 28. The cross-section of the rotating block 29 is a regular hexagon, and the axis of the rotating block 29 coincides with the axis of the threaded column 27.
[0029] It should be noted that the rectangular tube 24 can only move horizontally within the rectangular hole 22 by means of the rectangular plate 23. When the threaded column 27 rotates, the threaded column 27 can move upward or downward by means of the threaded tube 26. When the threaded column 27 presses against the rectangular plate 23, the hollow positioning column 28 cannot move due to the friction between the rectangular plate 23 and the threaded column 27. When the threaded column 27 separates from the rectangular plate 23, the rectangular tube 24 can slide horizontally on the rectangular plate 23. At the same time, by changing the position of the hollow positioning column 28 on the rectangular plate 23, the hollow positioning column 28 can be positioned for hubs of different diameters. The rotating block 29 allows workers to use tools such as wrenches to rotate the threaded column 27.
[0030] The working principle of this utility model is as follows: First, the wheel hub is placed on the disc 13 and the hollow positioning pin 28 is made to contact the inner wall of the wheel hub. At this time, the wheel hub is positioned by the hollow positioning pin 28. Then, the wheel hub on the right side of the first rotating shaft 4 is rotated to the left side of the first rotating shaft 4 by the first servo motor 3, and the disc 13 is made to contact the rubber roller 18. Then, the rubber roller 18 is driven to rotate by the second servo motor 16, and the wheel hub on the disc 13 is rotated around the cylinder 12 by the friction between the rubber roller 18 and the disc 13. Then, the surface of the wheel hub is scanned by the laser scanner 21, and the smoothness of the wheel hub is judged by the scanning result.
[0031] During the scanning process of the wheel hub surface by the laser scanner 21, the worker can place the next wheel hub on the disc 13 on the right side of the first rotating shaft 4 and make the hollow positioning post 28 contact the inner wall of the wheel hub. At this time, the wheel hub is positioned by the hollow positioning post 28. After the previous wheel hub is scanned, the next wheel hub is rotated to the left side of the first rotating shaft 4 by the first servo motor 3 and scanned. At the same time, the worker can replace the car wheel hub that has been inspected on the right disc 13.
[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
