Description

Technical Field

[0001] The utility model relates to the technical field of automobile processing, in particular to an automobile wheel hub wear resistance testing device. Background Art

[0002] The wheel hub is a cylindrical metal component with the center mounted on the shaft and the inner contour of the tire supporting the tire. It is also called the rim, steel ring, wheel, and tire bell. There are many types of wheel hubs according to diameter, width, molding method, and material. The wheel hub is also called the rim. According to the characteristics and needs of different models, the wheel hub surface treatment process will also adopt different methods, which can be roughly divided into two types: baking paint and electroplating. The appearance of the wheel hub of ordinary models is less considered. Good heat dissipation is a basic requirement. The process basically adopts baking paint treatment, that is, spraying first and then electric baking. The cost is relatively economical and the color is beautiful and lasts for a long time. Even if the vehicle is scrapped, the color of the wheel hub remains unchanged. Many Volkswagen models use baking paint as the surface treatment process of the wheel hub. Some fashionable, avant-garde and dynamic colored wheels also use baking paint technology. This type of wheel hub is moderately priced and has complete specifications. Electroplated wheels are divided into silver electroplating, water electroplating and pure electroplating.

[0003] In the prior art, traditional wheel hub testing devices only perform single-side grinding inspections when testing the wear resistance of the wheel hub, resulting in slow inspection speed and low work efficiency. This increases testing time and cost, and is not conducive to quickly obtaining test results. The long testing process may also lead to unstable test conditions, such as changes in environmental factors such as temperature and humidity, which may have an adverse effect on the test results, further reducing the accuracy and reliability of the test. In addition, due to the slow inspection speed, the entire test cycle is lengthened, which not only affects the R&D progress, but also increases production costs. Utility Model Content

[0027] In the embodiment of the present invention, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6, including a cabinet 1, a test component 2 is installed inside the cabinet 1, and the test component 2 includes a fixed disk 201 installed on the inner wall of the cabinet 1, one side of the fixed disk 201 is connected to a first turntable 202, one side of the first turntable 202 is connected to a plurality of connecting rods 203, one end of each connecting rod 203 is connected to a second turntable 204, one outer wall of one side of the first turntable 202 is connected to a push block 205, four fixed rods 206 are installed on the outer wall of the fixed disk 201, one end of the fixed rod 206 is connected to a clamp 207, the outer wall of the clamp 207 is slidably connected to a slider 208, a rotating shaft 209 is installed on one outer wall of one side of the slider 208, the bottom end of the clamp 207 is connected to a grinder 210, one side of the push block 205 is connected to a fixed block, and one outer wall of the fixed block is installed with a hydraulic rod 211.

[0028] It should be noted that the four grinding tools 210 can more accurately evaluate the overall wear resistance of the wheel hub, ensure the comprehensiveness and uniformity of the test results, and significantly shorten the test cycle, so that more test data can be obtained in the same time, thereby improving work efficiency.

[0029] See Figure 6 A mounting shell 3 is installed on one side of the top of the cabinet 1, and an adjustment component 4 is installed inside the mounting shell 3. The adjustment component 4 includes a rotating wheel 401 installed on the inner wall of the mounting shell 3, a first bevel gear 402 is installed in the middle of the rotating wheel 401, and the outer wall of the first bevel gear 402 is meshed with the second bevel gear 403. A sliding rod 404 is installed in the middle of the second bevel gear 403, and the outer wall of the sliding rod 404 is connected to a first push rod 405. The end of the first push rod 405 away from the sliding rod 404 is connected to the second push rod 406, and the other end of the second push rod 406 is connected to a rotating head 407.

[0030] It should be noted that: by virtue of the adjustable effect of the first push rod 405 on the slide rod 404, the distance pushed by the second push rod 406 can be changed according to demand, thereby enhancing the adaptability of the device.

[0031] See Figure 1 A control panel 5 is installed on one side of the top of the cabinet 1. A plurality of control buttons are installed on the outer wall of the control panel 5. The control panel 5 is electrically connected to the test component 2 and the adjustment component 4.

[0032] It should be noted that the use of the control panel 5 can make the device respond to the operator's operations more quickly, thereby improving work efficiency.

[0033] See Figure 1 A plurality of feet 6 are installed at the bottom of the cabinet 1. The number of the plurality of feet 6 is four. The four feet 6 are rectangular at the bottom of the cabinet 1. A shock-absorbing pad is installed at the bottom of each foot 6.

[0034] It should be noted that vibration damping pads can effectively absorb and disperse the vibration and impact force generated when mechanical equipment is running, reducing the vibration of the equipment during operation.

[0035] Working principle: After starting the control panel 5, the hydraulic rod 211 is started, and the hydraulic rod 211 drives the push block 205. When the push block 205 starts to rotate, the first turntable 202 fixedly connected to the push block 205 will rotate on one side of the fixed disk surface 201 according to the movement of the push block 205, and according to the rotation of the first turntable 202, it drives the second turntable 204 connected to the connecting rod 203. When the first turntable 202 rotates, the four fixed rods 206 fixedly connected to the outer wall of the fixed disk surface 201 will rotate according to the rotation, so that the rotating shaft 209 allows the inner wall of the slider 208 to slide on the outer wall of the clamp 207, and according to the sliding, the four clamps 207 contracts toward the center of the circle to clamp the wheel hub, and a grinder 210 is also installed at the bottom end of the clamp 207. The wear resistance of the wheel hub is tested by the grinder 210. If the model of the wheel hub is wider, the width of the grinder 210 is not enough to cover the outer wall of the wheel hub. By allowing the rotating wheel 401 to drive the second push rod 406 to move back and forth horizontally during rotation, and allowing the rotating head 407 to drive the wheel hub to rotate, the working surface of the grinder 210 can better cover the wheel hub, and by adjusting the first push rod 405 on the outer wall of the slide rod 404, the pushing distance of the second push rod 406 can be changed, and the working range of the wear resistance test can be adjusted according to the width of different wheel hubs.
