Description

Technical Field

[0001] This utility model belongs to the field of wheel hub testing technology, specifically relating to a wheel hub balance testing device. Background Technology

[0002] The smoothness of a car's ride is a major standard for judging its comfort. In addition to ensuring that the car's cushioning system works properly, the dynamic balance of the car's wheels is also an important factor. Due to certain errors that occur during the wheel manufacturing process, the wheels are not perfect circles. Generally, errors within the allowable range will not affect the normal driving of the car. However, when the error exceeds the limit, the car will bounce while driving. This will affect the comfort of the car during the ride and reduce the driver's control over the car, making it easier for accidents to occur at high speeds.

[0003] Currently, when using testing equipment to check the balance of wheel hubs, the wheel hub is usually fixed to the testing equipment first. Then, the reading of the electronic dial indicator on the testing equipment is used to determine whether the wheel hub is qualified. For example, a dynamic balancing testing fixture for automobile wheel hubs disclosed in Chinese Patent Publication No. CN108775842B. However, when fixing the wheel hub to the testing equipment, multiple bolts and nuts are required to fix the wheel hub to the testing equipment, which makes the testing equipment more cumbersome to use. At the same time, the position of the electronic dial indicator needs to be adjusted manually by the user, which makes the adjustment of the electronic dial indicator more troublesome.

[0025] 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.

[0026] 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.

[0027] like Figures 1 to 10As shown, a wheel hub balance testing device includes a workbench 1, with support legs 2 fixedly connected to the bottom of the workbench 1. A circular hole 3 is formed inside the workbench 1, and a bearing 4 is fixedly connected to the inner wall of the circular hole 3. A cylinder 5 is fixedly connected to the inner ring of the bearing 4. A first cylinder 6 is fitted against the inner wall of the cylinder 5. A first circular plate 7 is fixedly connected to the upper surface of the first cylinder 6. A first U-shaped plate 8 is fixedly connected to the bottom of the first circular plate 7. Fixing posts 9 are fitted against both the inner wall of the first U-shaped plate 8 and the bottom of the first circular plate 7. A hollow block 10 is fixedly connected to the surface of the cylinder 5, and a second U-shaped plate 11 is fixedly connected to the surface of the hollow block 10. A fixing post 9 is fixedly connected to the inner wall of the second U-shaped plate 11. A vertical plate 13 is attached to the inner wall of the second cylinder 12 and the second U-shaped plate 11. A strip hole 14 is opened inside the vertical plate 13. The inner wall of the strip hole 14 is attached to the surface of the second cylinder 12. The upper surface of the vertical plate 13 is fixedly connected to the bottom of the fixed column 9. A first electric telescopic rod 15 is fixedly connected to the upper surface of the workbench 1. A first mounting plate 16 is fixedly connected to the top of the first electric telescopic rod 15. A drive mechanism 17 is fixedly connected to the bottom of the first mounting plate 16. A moving mechanism 18 is fixedly connected to the upper surface of the workbench 1. An electronic dial indicator 19 is connected to the upper surface of the moving mechanism 18. Springs 20 are fixedly connected to the upper surface of the cylinder 5 and the bottom of the first circular plate 7.

[0028] The width of the strip hole 14 is equal to the diameter of the second cylinder 12, the length of the strip hole 14 is greater than the diameter of the second cylinder 12, the angle between the strip hole 14 and the horizontal plane is 30°, the axis of the rotating shaft 172 coincides with the axis of the first cylinder 6, and there are four fixed columns 9, which are arranged in a circular array with the first cylinder 6 as the center.

[0029] The drive mechanism 17 includes a drive motor 171, a rotating shaft 172, a second circular plate 173, and a rubber pad 174. The upper surface of the drive motor 171 is fixedly connected to the bottom of the first mounting plate 16, the output end of the drive motor 171 is fixedly connected to the top end of the rotating shaft 172, the bottom end of the rotating shaft 172 is fixedly connected to the upper surface of the second circular plate 173, and the bottom of the second circular plate 173 is bonded to the upper surface of the rubber pad 174.

[0030] It should be noted that the bearing 4 allows the cylinder 5 to rotate freely within the circular hole 3, the spring 20 supports the first circular plate 7, and the first U-shaped plate 8 allows the fixed column 9 to move only horizontally. When the first circular plate 7 moves downward due to pressure, the distance between the fixed column 9 and the first cylinder 6 increases through the cooperation of the first U-shaped plate 8, the fixed column 9, the hollow block 10, the second U-shaped plate 11, the second cylinder 12, the vertical plate 13, and the strip hole 14. When the downward pressure on the first circular plate 7 decreases, the spring 20 causes the first circular plate 7 to move upward, and the first U-shaped plate 8, the fixed column 9, the hollow block 10, the second U-shaped plate 11, the second cylinder 12, and the vertical plate 13 further contribute to the upward movement. The cooperation between the fixed post 9 and the first cylinder 6 reduces the distance between the fixed post 9 and the first cylinder 6. When the fixed post 9 contacts the inner wall of the hub, the hub can be fixed on the first circular plate 7 through the fixed post 9. When the fixed post 9 is separated from the hub, the hub can be directly removed from the first circular plate 7. When the upper surface of the hub contacts the rubber pad 174 of the drive mechanism 17, the friction between the rubber pad 174 and the hub enables the drive motor 171 to drive the hub to rotate. When the hub rotates, the maximum reading of the electronic dial indicator 19 is read. When the maximum reading is within the allowable error range, the hub is a qualified product. When the maximum reading exceeds the allowable error range, the hub is a defective product.

[0031] like Figures 1 to 10 As shown, the moving mechanism 18 includes a second mounting plate 181, a guide plate 182, a rectangular tube 183, a connecting block 184, a second electric telescopic rod 185, a third electric telescopic rod 186, and an L-shaped plate 187. The bottom of the second mounting plate 181 is fixedly connected to the upper surface of the workbench 1. The upper surface of the second mounting plate 181 is fixedly connected to the bottom of the guide plate 182. The surface of the guide plate 182 is in contact with the inner wall of the rectangular tube 183. The left side of the rectangular tube 183 is fixedly connected to the right side of the connecting block 184. The upper and lower ends of the second electric telescopic rod 185 are fixedly connected to the upper surface of the second mounting plate 181 and the bottom of the connecting block 184, respectively. The left side of the connecting block 184 is fixedly connected to the right end of the third electric telescopic rod 186. The left end of the third electric telescopic rod 186 is fixedly connected to the right side of the L-shaped plate 187. The upper surface of the L-shaped plate 187 is fixedly connected to the bottom of the electronic micrometer 19. The bottom of the L-shaped plate 187 is in contact with the upper surface of the connecting block 184.

[0032] It should be noted that, through the cooperation of the rectangular cylinder 183 and the guide plate 182, the connecting block 184 can only move up and down. The second electric telescopic rod 185 can control the automatic up and down movement of the connecting block 184, and the third electric telescopic rod 186 can control the automatic left and right movement of the L-shaped plate 187. Furthermore, through the cooperation of the second mounting plate 181, the guide plate 182, the rectangular cylinder 183, the connecting block 184, the second electric telescopic rod 185, the third electric telescopic rod 186, and the L-shaped plate 187, the position of the electronic micrometer 19 can be automatically adjusted according to the size of the wheel hub, thus making the testing equipment more convenient to use.

[0033] The working principle of this utility model is as follows: First, the hub is placed on the first circular plate 7, and the inner wall of the hub is in contact with the upper surface of the first circular plate 7. Then, through the first electric telescopic rod 15, the rubber pad 174 is brought into contact with the hub, and the rubber pad 174 exerts downward pressure on the hub. At this time, the pressure causes the first circular plate 7 to move downward. Through the cooperation of the first U-shaped plate 8, the fixing post 9, the hollow block 10, the second U-shaped plate 11, the second cylinder 12, the vertical plate 13 and the strip hole 14, the distance between the fixing post 9 and the first cylinder 6 is increased. When the fixing post 9 contacts the inner wall of the hub, the hub can be fixed on the first circular plate 7 through the fixing post 9.

[0034] Then, through the cooperation of the second electric telescopic rod 185 and the third electric telescopic rod 186, the measuring end of the electronic micrometer 19 is brought into contact with the surface of the wheel hub. By turning on the drive motor 171, the rubber pad 174 is rotated. At this time, through the friction between the rubber pad 174 and the wheel hub, the drive motor 171 can drive the wheel hub to rotate. When the wheel hub rotates, the maximum reading of the electronic micrometer 19 is read. When the value of the maximum reading is within the allowable error range, the wheel hub is a qualified product. When the value of the maximum reading exceeds the allowable error range, the wheel hub is a defective product.

[0035] 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.
