Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wheel hub testing technology, specifically relating to a wheel hub corrosion resistance testing device. Background Technology
[0002] In the automotive manufacturing and related industries, the corrosion resistance of wheel hubs is a crucial indicator of their quality. Currently, corrosion resistance testing of wheel hubs typically involves immersing them in a corrosive liquid for a certain period before observation. However, after removal, the wheel hub surface absorbs a large amount of corrosive liquid. This liquid not only affects the accurate observation of the corrosion condition but also allows residual corrosive liquid to continue corroding the wheel hub, impacting the accuracy of the test results and the wheel's subsequent use. Existing methods often involve manual wiping, which is inefficient and may cause secondary damage to the wheel hub surface, affecting the test results. Utility Model Content

[0025] 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.
[0026] like Figures 1 to 9As shown, a wheel hub corrosion resistance testing device includes a base plate 1. A first electric push rod 2 is fixedly connected to the upper surface of the base plate 1. A barrel 3 is fixedly connected to the upper surface of the first electric push rod 2. First rectangular holes 4 are opened on both the left and right sides of the barrel 3. A horizontal plate 5 is fitted into the inner wall of the first rectangular holes 4. A cylinder 6 is fitted onto the surface of the barrel 3. Second rectangular holes 7 are opened on both the left and right sides of the cylinder 6. The inner wall of the second rectangular holes 7 is fixedly connected to the surface of the horizontal plate 5. A spring 8 is fixedly connected to the bottom of the horizontal plate 5. A first mounting base 9 is fixedly connected to the bottom of the spring 8 and the upper surface of the base plate 1. A U-shaped bracket 10 is fixedly connected to the upper surface of the horizontal plate 5. The top of the inner wall of the U-shaped bracket 10 is fixedly connected to... The second mounting bracket 11 is fixedly connected to the bottom of the second mounting bracket 11, and the bottom of the second electric push rod 12 is fixedly connected to the bottom of the second electric push rod 12. The bottom of the horizontal plate 5 is fixedly connected to the bottom of the rectangular ring 14. The upper surface of the base plate 1 is fixedly connected to the drive mechanism 15. The surface of the drive mechanism 15 is in contact with the inner wall of the rectangular ring 14. The interior of the horizontal plate 5 has a liquid permeation hole 16. The center of the horizontal plate 5 coincides with the axis of the barrel 3. The liquid permeation hole 16 is located inside the barrel 3. The upper surface of the horizontal plate 5 is fixedly connected to the positioning ring 23. The axis of the positioning ring 23 coincides with the center of the horizontal plate 5. The bottom of the barrel 3 is fixedly connected to the drain pipe 24. The bottom of the drain pipe 24 is fixedly connected to the valve 25.
[0027] The drive mechanism 15 includes a third mounting base 151, a drive motor 152, a rotating shaft 153, a disc 154, and a cylinder 155. The bottom of the third mounting base 151 is fixedly connected to the upper surface of the base plate 1. The upper surface of the third mounting base 151 is fixedly connected to the bottom of the drive motor 152. The output end of the drive motor 152 is fixedly connected to one end of the rotating shaft 153. The surface of the rotating shaft 153 is fixedly connected to the inner wall of the disc 154. The left side of the disc 154 is fixedly connected to the right end of the cylinder 155. The surface of the cylinder 155 is in contact with the inner wall of the rectangular ring 14.
[0028] It should be noted that the first electric push rod 2 can control the barrel 3 to move up or down. When the hub is fixed on the horizontal plate 5, the upward movement of the barrel 3 allows the corrosive liquid inside the barrel 3 to come into contact with the hub. When the barrel 3 moves downward, the corrosive liquid inside the barrel 3 can quickly separate from the hub. Furthermore, the corrosive liquid above the horizontal plate 5 can drip down through the liquid-permeable hole 16. Through the cooperation of the first rectangular hole 4 and the cylinder 6, the horizontal plate 5 can only move up and down, and the spring 8 supports the horizontal plate 5. The second electric push rod 12 can control the pressing plate 13 to move up or down. When the pressing plate 13 presses the hub on the horizontal plate 5, the hub is fixed on the horizontal plate 5 by the pressing plate 13. When the pressing plate 13 is separated from the hub, the hub can be directly removed from the horizontal plate 5. The positioning ring 23 can be used to position the hub placed on the horizontal plate 5. The valve 25 controls the opening and closing of the drain pipe 24. When the valve 25 is opened, the corrosive liquid in the barrel 3 can be discharged through the drain pipe 24.
[0029] The cylinder 155 on the disc 154 can rotate around the shaft 153 by the drive motor 152. When the cylinder 155 rotates around the shaft 153, the horizontal plate 5 can be shaken up and down by the cooperation of the cylinder 6, spring 8, first mounting seat 9, drive mechanism 15 and rectangular ring 14. At this time, the corrosive liquid adsorbed on the surface of the hub can be shaken off efficiently and quickly by shaking.
[0030] like Figures 1 to 11 As shown, an arc-shaped rubber strip 17 is attached to the bottom of the cylinder 6. The inner wall of the arc-shaped rubber strip 17 is attached to the surface of the barrel 3. A first circular hole 18 is opened inside the arc-shaped rubber strip 17. A threaded cylinder 19 is fixedly connected to the inner wall of the first circular hole 18. A circular ring 20 is fixedly connected to the surface of the cylinder 6. A second circular hole 21 is opened inside the circular ring 20. A fixing bolt 22 is attached to the inner wall of the second circular hole 21. The surface of the fixing bolt 22 is threadedly connected to the inner wall of the threaded cylinder 19.
[0031] It should be noted that the bottom of the cylinder 6 has four arc-shaped rubber strips 17 with an arc of 45°. The arc-shaped rubber strips 17 can seal the connection between the cylinder 6 and the barrel 3, so that the corrosive liquid inside the barrel 3 is not easy to leak out from the connection between the cylinder 6 and the barrel 3. At the same time, through the cooperation of the threaded cylinder 19, the ring 20, the second circular hole 21 and the fixing bolt 22, the arc-shaped rubber strips 17 and the cylinder 6 can be quickly disassembled and assembled, so as to facilitate the user to replace the worn arc-shaped rubber strips 17.
[0032] The working principle of this utility model is as follows: First, the corrosive liquid is poured into the barrel 3. Then, the barrel 3 is moved downward by the first electric push rod 2. When the liquid level of the corrosive liquid is below the horizontal plate 5, the first electric push rod 2 stops controlling the barrel 3 to move downward. Then, the wheel hub is placed on the horizontal plate 5 and positioned by the positioning ring 23. Then, the pressing plate 13 is pressed by the second electric push rod 12 and the wheel hub is fixed on the horizontal plate 5 by the pressing force.
[0033] Then, the first electric push rod 2 moves the barrel 3 upward. After the wheel hub is completely immersed in the corrosive liquid, the first electric push rod 2 stops controlling the barrel 3 to move upward. At this time, the corrosion resistance of the wheel hub is tested by immersing it in the corrosive liquid. After the wheel hub has been immersed for a period of time, the first electric push rod 2 controls the barrel 3 to move downward. When the liquid level of the corrosive liquid is below the horizontal plate 5, the first electric push rod 2 stops controlling the barrel 3 to move downward.
[0034] Then, start the drive motor 152, which causes the cylinder 155 to rotate around the shaft 153. Through the cooperation of the cylinder 6, spring 8, first mounting base 9, drive mechanism 15 and rectangular ring 14, the horizontal plate 5 can be shaken up and down. At this time, the corrosive liquid adsorbed on the surface of the wheel hub can be shaken off efficiently and quickly by shaking.
[0035] After the corrosive liquid on the surface of the wheel hub is shaken off, the pressing plate 13 is separated from the wheel hub by the second electric push rod 12. Then, the wheel hub is removed from the horizontal plate 5, and the corrosion resistance of the wheel hub can be calculated by observing the corrosion condition of the wheel hub.
[0036] 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.
