Description

Technical Field

[0001] The present invention belongs to the technical field of wheel hub detection, and more specifically, particularly relates to a wheel hub dynamic balance detection device. Background Art

[0002] Wheel dynamic balancing test is a test process used to confirm whether the wheel and tire are balanced when rotating. When performing wheel dynamic balancing test, the wheel and tire are usually tested as a whole. This is because only when the wheel and tire participate in the dynamic balancing test together can the balance of the entire wheel system be accurately evaluated to ensure the stability and comfort of the vehicle during driving. By testing the wheel and tire at the same time, the imbalance between the two can be discovered and adjusted in time, avoiding adverse conditions such as vibration and shaking during vehicle driving due to problems with the wheel or tire itself.

[0003] 1. When the existing device is in use, due to complex road conditions, hard impurities such as pebbles are often stuck in the tire of the wheel hub assembly when driving on a gravel road. In order to avoid affecting the subsequent inspection of the wheel hub assembly, the staff usually needs to use tools such as screwdrivers to clean the hard impurities such as pebbles stuck in the drainage ditch inside the tire on the wheel hub. However, due to the heavy overall weight of the wheel hub assembly, and when the staff use the lifter to lift out the pebbles, the staff is prone to misoperation, and the front end of the lifter is easily guided to the drainage ditch, thereby damaging the drainage ditch, which is inconvenient to clean.

[0004] 2. When the existing device is in use, due to the complex road conditions during driving, when passing through a mud pit with accumulated water or a gravel road with many dirt and impurities, the inner diameter surface of the wheel rim of the hub assembly is often stained with a lot of dirt and impurities. In order to avoid affecting the subsequent inspection, the staff often needs to clean the inner diameter surface of the wheel rim of the hub assembly before the inspection. However, since the wheel hub assembly is heavy and the inner diameter surface of the wheel rim is usually narrow, it is more troublesome to clean it;

[0005] 3. When the existing device is in use, due to the heavy overall weight of the wheel hub assembly and the lack of a mechanism for cleaning the drainage grooves of the wheel hub assembly and the inner diameter surface of the wheel rim, it needs to be moved multiple times when cleaning the drainage grooves of the wheel hub assembly and the inner diameter surface of the wheel rim, thereby increasing the labor burden of the staff and the practicality needs to be improved.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the present invention, by installing the wheel hub assembly on the rotating shaft and turning on the motor, the motor can drive the screw rod on the rectangular block to rotate in the second through groove and perform threaded transmission with the slider, so that the slider as a whole slides in the slide groove, and then the spacing between the scraper rods can be adjusted according to the distribution of the drainage grooves on the tire on the wheel hub assembly, thereby increasing the overall applicability of the device, and when the scraper rod is located in the drainage groove, the small stones stuck in the drainage groove in the wheel hub assembly can be cleaned when the wheel hub assembly is rotated subsequently, which is more convenient to use;

[0016] In the present invention, by turning on the motor, the slider as a whole slides in the slide groove, and drives the scraper rod to move longitudinally on the outer surface of the hub assembly, and when the scraper rod contacts the drainage ditch, the spring automatically resets and drives the connecting frame to descend, so that the connecting frame pushes the square plate and the scraper rod to descend as a whole and contact the bottom of the drainage ditch, thereby achieving the effect of completing the scraper rod adaptive insertion according to the depth of the drainage ditch, without the need for additional adjustment, reducing the difficulty of operation;

[0017] In the present invention, when the scraper rod enters the bottom of the drainage ditch as a whole, the threaded rod is rotated so that the nut and the threaded rod are threadedly transmitted and the limit block is driven to slide upward in the limit groove in the fixed plate. When the nut contacts the circular groove, since the diameter of the nut is larger than the diameter of the circular groove, the nut can lift up the connecting frame, thereby stretching the spring. At the same time, the connecting frame will drive the square plate and the scraper rod to slide upward in the straight groove group. At this time, the scraper rod will no longer fit with the bottom of the drainage ditch, thereby preventing the scraper rod from fitting tightly with the drainage ditch when the wheel hub assembly rotates, thereby preventing the drainage ditch from being damaged.

[0018] In the present invention, when the wheel hub assembly rotates, once the wheel hub assembly has a problem with its balance, the wheel hub assembly will generate unbalanced centrifugal force due to the rotation, thereby causing the tire of the wheel hub assembly to bounce to a certain extent. At this time, the scraper rod located in the drainage ditch will fit the bottom of the drainage ditch again, but because the top of the connecting frame is not fixed, a radial force will be generated at the bottom of the drainage ditch to make the scraper rod push the square plate and lift the connecting frame, so that the spring is stretched again, thereby preventing the scraper rod from continuously contacting the drainage ditch when facing an unbalanced wheel hub assembly, thereby causing unnecessary damage to the wheel hub assembly;

[0019] In the present invention, by providing the slide groove and the limit block, necessary limit can be provided for the threaded transmission between the slider and the screw rod and the threaded transmission between the threaded rod and the nut, and additional support can be provided to increase stability.

[0020] In the present invention, when the rotating shaft is turned on for rotation, the rotation of the rotating shaft will drive the wheel hub assembly to rotate together. At this time, the rotating shaft will drive the first gear to rotate through the synchronous belt, and the first gear will mesh with the second gear, so that the second gear as a whole drives the rotating rod to rotate, and the rotation direction is opposite to that of the wheel hub assembly. Due to the rotation of the rotating rod, the rotating rod will drive the cleaning roller and the friction layer on the cleaning roller to rotate together and rub against the raised pebbles or small mud blocks remaining on the inner wall of the inner diameter surface of the rim, thereby playing a role in cleaning the inner wall of the wheel hub assembly, and then the remaining small mud and pebbles on the inner diameter surface of the rim can be cleaned, thereby effectively reducing the labor burden of the staff and increasing practicality.

[0039] A rotating shaft 34 is provided on the side wall of the dynamic balancing detection device body 11, and the rotating shaft 34 is located below the protective cover 12. A hub assembly 35 is provided on the circumferential surface of the rotating shaft 34, and a drainage ditch 36 is provided on the circumferential surface of the hub assembly 35. A wheel rim inner diameter surface 37 is provided on the inner wall of the hub assembly 35, and each scraper rod 25 is located inside the drainage ditch 36. Two fixed brackets 38 are fixedly installed on the side wall of the dynamic balancing detection device body 11, and a fixed block 39 is fixedly installed between the fixed brackets 38. A first gear 41 is rotatably installed on the side wall of the fixed block 39, and a synchronous belt 42 is rotatably installed between the first gear 41 and the rotating shaft 34.

When the rotating shaft 34 is turned on for rotation, the rotation of the rotating shaft 34 will drive the wheel hub assembly 35 to rotate together. At this time, the rotating shaft 34 will drive the first gear 41 to rotate through the synchronous belt 42, and the first gear 41 will mesh with the second gear 45, so that the second gear 45 drives the rotating rod 44 as a whole to rotate, and the rotation direction is opposite to that of the wheel hub assembly 35. Due to the rotation of the rotating rod 44, the rotating rod 44 will drive the cleaning roller 46 and the friction layer 47 on the cleaning roller 46 to rotate together and rub against the impurities remaining on the inner wall of the inner diameter surface 37 of the wheel rim, thereby playing a role in cleaning the inner wall of the wheel hub assembly 35, and then the raised small mud and pebbles on the inner diameter surface 37 of the wheel rim can be cleaned, thereby effectively reducing the labor burden of the staff and increasing practicality.

[0040] Working principle:

[0041] The first step is that before use, the initial positions of the threaded rod 31 and the nut 32 should be located on the upper surface of the slider 21 and in a fitted state. When it is needed, the hub assembly 35 can be first installed on the rotating shaft 34, and then the protective cover 12 can be closed on the hub assembly 35. At this time, the scraper rod 25 will be pressed against the surface outside the hub assembly 35, so that the scraper rod 25 pushes the square plate 24 and the connecting frame 23 upward as a whole. At this time, the spring 27 will be stretched to a certain extent, and then the motor 16 can be turned on according to the spacing between the drainage grooves 36 on the hub assembly 35, so that the motor 16 can be turned on. The lever 16 drives the screw rod 19 to rotate in the second through groove 17 on the rectangular block 15, so that the slide groove 18 and the slider 21 are threadedly driven, so that the slider 21 slides in the slide groove 18 as a whole. At this time, the slider 21 will drive the scraper rod 25 to move longitudinally on the outer surface of the hub assembly 35. When the scraper rod 25 is located in the drainage ditch 36 on the hub assembly 35, the screw rod 19 can be closed. When the scraper rod 25 is located in the drainage ditch 36, the spring 27 will be reset, thereby pulling the connecting frame 23 down as a whole, thereby pushing the scraper rod 25 into the bottom of the drainage ditch 36 as a whole.

[0042] In the second step, the remaining scraper rods 25 can be pushed into the bottom of the drainage ditch 36 according to the above steps, and then the threaded rod 31 can be rotated, so that the nut 32 and the threaded rod 31 are threadedly transmitted and drive the limit block 33 to slide upward in the limit groove 29 in the fixing plate 28. When the nut 32 contacts the circular groove 26, the threaded rod 31 can be rotated two circles again, so that the nut 32 lifts the connecting frame 23. At this time, the connecting frame 23 will drive the square plate 24 and the scraper rod 25 to slide upward in the straight groove group 22. At this time, the scraper rod 25 will no longer fit the bottom of the drainage ditch 36, and then the remaining three threaded rods 31 can be rotated according to the above operation;

[0043] In the third step, the dynamic balancing detection device body 11 can be controlled to start the rotating shaft 34 to rotate. At this time, the rotation of the rotating shaft 34 will drive the hub assembly 35 to rotate together, and the part of the impurities stuck in the drainage ditch 36 will contact the scraper rod 25 and lift the impurities out of the drainage ditch 36. When the rotating shaft 34 rotates, it will drive the first gear 41 to rotate through the synchronous belt 42, and the first gear 41 will mesh with the second gear 45, so that the second gear 45 as a whole drives the rotating rod 44 to rotate, and the direction of rotation is opposite to that of the hub assembly 35. Due to the rotation of the rotating rod 44, the rotating rod 44 will drive the cleaning roller 46 and the friction layer 47 on the cleaning roller 46. It rotates and rubs against the inner wall of the inner diameter surface 37 of the wheel rim (a small gap is left between the friction layer 47 on the cleaning roller 46 and the inner wall of the hub assembly 35), thereby cleaning the inner wall of the hub assembly 35. At this time, impurities in the hub assembly 35 and the drainage ditch 36 will fall into the collection box 48. The team members can then use a vacuum cleaner to simply vacuum the inner wall of the inner diameter surface 37 of the hub assembly 35. Then, they can take the data on the hub assembly 35 and upload it to the dynamic balancing detection device body 11, then pull the connecting frame 23 upwards and reset the motor 16, and then start the balancing detection device body 11 and the rotating shaft 34 for formal detection.
