Description

Technical Field

[0001] This utility model relates to the field of maintenance equipment technology, specifically to an automotive wheel hub maintenance device. Background Technology

[0002] Wheel rims, also known as wheel hubs, undergo different surface treatment processes depending on the characteristics and needs of different car models. These can be broadly categorized into two types: painted and electroplated. For ordinary car models, aesthetics are less of a concern; good heat dissipation is a basic requirement. Painted wheels are typically used, involving spraying and then electroplating. This process is relatively economical, produces vibrant colors, and maintains their color for a long time; even after the vehicle is scrapped, the wheel rim color remains unchanged. However, wheel rims may develop damage or internal cracks after prolonged use. Therefore, flaw detection is necessary when repairing or replacing wheel rims. Traditional inspection methods often involve manual handheld flaw detectors, which are inefficient. To improve the inspection of car wheel rims, a new car wheel rim inspection device has been proposed.

[0003] For example, the automobile wheel hub inspection device disclosed in the authorization announcement number CN223259604U includes a base and a wheel hub body. The wheel hub body is set on the top of the base. A rotating component and a fixed frame are respectively installed on the top of the base. The rotating component is located inside the fixed frame, and the wheel hub body is located above the rotating component. Monitoring cameras are fixedly installed on both sides inside the fixed frame, and a lifting component is provided on the fixed frame.

[0004] Although it achieves the clamping of the wheel hub body by clamping components on two connecting blocks, the first electric push rod drives the connecting blocks, which in turn drives the wheel hub body clamped in the clamping components to rise. Then, the first motor drives the active synchronous pulley, which in turn drives the driven synchronous pulley through the synchronous belt. As a result, the clamping components rotate, which can drive the wheel hub body to flip. Thus, after one side of the wheel hub body has been inspected, it does not need to be manually removed and flipped, which saves time and effort and improves inspection efficiency.

[0005] However, this does not solve the problem that the existing maintenance device is not conducive to the circumferential rotation adjustment of the wheel hub during use, which is not conducive to the comprehensive flaw detection and maintenance of the wheel hub, thus affecting the efficiency of maintenance. Utility Model Content

[0006] The purpose of this utility model is to provide an automotive wheel hub inspection device to solve the problem mentioned in the background art that the inspection device is not convenient for circumferentially rotating and adjusting the inspection position of the wheel hub, which is not conducive to comprehensive flaw detection and inspection of the wheel hub and affects the efficiency of the inspection.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A vehicle wheel hub repair device includes a repair platform and a placement seat. The placement seat is slidably mounted on the top of the repair platform. A limit post is provided at the center of the placement seat. A sliding sleeve is slidably mounted on the surface of the limit post. Multiple sets of springs at equal intervals are provided at the bottom end of the sliding sleeve. Three sets of sliding rods at equal intervals are movably mounted on the side wall of the sliding sleeve and are slidably connected to the placement seat. The sliding rods can extend to the outside of the placement seat. Three sets of side ears at equal intervals are provided on the outer wall of the placement seat. Each side ear is provided with a clamping arm inside.

[0008] Optionally, each of the clamping arms is provided with a hinge shaft on its side wall, and the clamping arm is movably connected to the side ear through the hinge shaft.

[0009] Optionally, the slide bar is slidably connected to the clamping arm, and the top of each clamping arm is provided with a clamping block.

[0010] Optionally, a support frame is provided at the top of the maintenance platform on one side of the placement seat, and a first cylinder is provided at the top of the support frame.

[0011] Optionally, the output end of the first cylinder is provided with a first push arm, the bottom end of the first push arm is provided with a movable plate, and both ends of the movable plate are provided with side ultrasonic probes.

[0012] Optionally, limit rods are provided at the top of the movable plates on both sides of the first push arm, and the limit rods are slidably connected to the support frame, and an adjustment frame is provided at the bottom of the movable plate.

[0013] Optionally, a bidirectional lead screw is movably installed inside the adjustment frame, and a second servo motor is provided on the side wall of the adjustment frame, with the output end of the second servo motor connected to the bidirectional lead screw.

[0014] Optionally, the surface of the bidirectional lead screw is fitted with two sets of threaded sleeves, and the threaded sleeves are threadedly connected to the bidirectional lead screw, and each threaded sleeve is provided with a lower ultrasonic probe at its bottom end.

[0015] Optionally, a first servo motor is provided at the top of the inspection platform on the other side of the placement seat. The output end of the first servo motor is provided with a drive shaft. The bottom end of the placement seat is provided with a movable shaft, and a pulley assembly extends to the surface of the movable shaft. The movable shaft is movably connected to the inspection platform.

[0016] Optionally, a PLC controller is provided on the top of the maintenance platform on one side of the first servo motor, and the output terminal of the PLC controller is electrically connected to the first cylinder, the second servo motor, the side ultrasonic probe, and the input terminal of the first servo motor.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the maintenance device not only realizes the maintenance position of the wheel hub by circumferential rotation, which facilitates comprehensive flaw detection and maintenance of the wheel hub, but also improves the efficiency of maintenance.

[0018] With the blank side of the wheel hub facing upwards, the center hole of the wheel hub is fitted onto the surface of the limiting post. Under the weight of the wheel hub itself, the wheel hub drives the sliding sleeve to move downwards on the surface of the limiting post, and the sliding sleeve compresses the spring. The sliding sleeve drives the sliding rod to slide inside the placement seat, and the sliding rod drives the clamping arm to rotate around the hinge axis. The clamping arm drives the clamping blocks to rotate, and the three sets of clamping blocks rotate synchronously and contact the outer wall of the wheel hub to clamp and fix the wheel hub. When it is necessary to remove the wheel hub, move the wheel hub upwards. With the elastic cooperation of the spring, the spring drives the sliding sleeve to return to its original position, and the clamping arm drives the clamping blocks away from the wheel hub, thus removing the wheel hub. The first cylinder drives the second... A push arm moves downwards, driving the side and lower ultrasonic probes to the inside of the hub. The side and lower ultrasonic probes then inspect the inner wall and bottom of the hub, respectively. A first servo motor drives a pulley assembly via a drive shaft, which in turn rotates a movable shaft. This movable shaft then rotates the mounting base and the hub, allowing the side and lower ultrasonic probes to inspect different locations on the inner wall and bottom of the hub. This improves the efficiency of the inspection process and prepares the hub for subsequent repairs. The circular rotation adjustment of the hub's inspection position enhances inspection efficiency.

[0019] During the rotation of the wheel hub, the second servo motor drives the bidirectional lead screw to rotate, which in turn drives two sets of threaded sleeves to move in opposite directions. The threaded sleeves then move the lower ultrasonic probes closer to or further away from each other, thereby adjusting the inspection position of the lower ultrasonic probes laterally. This facilitates a more comprehensive flaw detection and inspection of the bottom of the wheel hub, avoiding any omissions in the inspection. It also allows for flexible adjustment of the inspection position, enabling comprehensive flaw detection and inspection of the wheel hub and improving the overall inspection effect.

[0029] like Figures 1 to 5 As shown, an embodiment of this utility model provides an automotive wheel hub repair device, including a repair bench 1 and a placement seat 4. The placement seat 4 is slidably disposed on the top of the repair bench 1. A limit post 24 is disposed at the center of the interior of the placement seat 4. A sliding sleeve 23 is slidably disposed on the surface of the limit post 24. Multiple sets of springs 25 at equal intervals are disposed at the bottom end of the sliding sleeve 23. Three sets of sliding rods 26 at equal intervals are movably mounted on the side wall of the sliding sleeve 23. The sliding rods 26 are slidably connected to the placement seat 4 and can extend to the outside of the placement seat 4. Three sets of side ears 19 at equal intervals are disposed on the outer wall of the placement seat 4. A clamping arm 21 is disposed inside the side ear 19. A hinge shaft 20 is disposed on the side wall of the clamping arm 21. The clamping arm 21 is movably connected to the side ear 19 through the hinge shaft 20. The sliding rod 26 is slidably connected to the clamping arm 21. A clamping block 22 is disposed at the top of the clamping arm 21.

[0030] A support frame 5 is installed at the top of the inspection platform 1 on one side of the placement seat 4. A first cylinder 9 is installed at the top of the support frame 5, and the first cylinder 9 plays the role of power drive.

[0031] The output end of the first cylinder 9 is provided with a first push arm 11, the bottom end of the first push arm 11 is provided with a movable plate 12, and both ends of the movable plate 12 are provided with side ultrasonic probes 13.

[0032] Limiting rods 10 are provided at the top of the movable plates 12 on both sides of the first push arm 11, and the limiting rods 10 are slidably connected to the support frame 5. An adjustment frame 18 is provided at the bottom of the movable plate 12.

[0033] In this utility model, the PLC controller 3 is a Siemens S7-200, which is existing technology. Therefore, its internal structure, working principle, and connection and control method with the electrical components in this application will not be described in detail. With the blank side of the hub facing upwards, the center hole of the hub is fitted onto the surface of the limiting post 24. Under the weight of the hub itself, the hub drives the sliding sleeve 23 to move downwards on the surface of the limiting post 24 and compresses the spring 25. The sliding sleeve 23 drives the sliding rod 26 to slide inside the placement seat 4. The clamping arm 21 rotates around the hinge shaft 20, causing the clamping blocks 22 to rotate. The three sets of clamping blocks 22 rotate synchronously and contact the outer wall of the wheel hub to clamp and fix it. When the wheel hub needs to be removed, it is moved upwards. With the elastic cooperation of the spring 25, the spring 25 drives the sliding sleeve 23 to return to its original position. With the linkage cooperation of the sliding rod 26 and the clamping arm 21, the clamping arm 21 drives the clamping blocks 22 away from the wheel hub, thus removing the wheel hub. Then, the first cylinder 9 is opened, causing the first push arm 1 to... 1. Moving downwards, under the sliding cooperation of the limiting rod 10 and the support frame 5, the first push arm 11 drives the side ultrasonic probe 13 and the lower ultrasonic probe 15 to move into the inside of the hub. The side ultrasonic probe 13 and the lower ultrasonic probe 15 respectively perform flaw detection and repair on the inner wall and bottom of the hub. The side ultrasonic probe 13 and the lower ultrasonic probe 15 are products of the same type as the Olympus EPOCH-650. Their working principle is that ultrasonic waves will be strongly reflected when passing through the interface of tissues with different acoustic impedances. Based on the different reflection data, the image data inside the test object is obtained. At the same time, the first servo motor 2 is turned on, and the first servo motor 2 drives the pulley assembly 7 to move through the drive shaft 6. The pulley assembly 7 drives the movable shaft 8 to rotate, and the movable shaft 8 drives the placement seat 4 and the hub to rotate. Thus, the side ultrasonic probe 13 and the lower ultrasonic probe 15 can perform flaw detection and repair on different positions of the inner wall and bottom of the hub, which can improve the efficiency of flaw detection and repair, and thus prepare for the subsequent repair of the hub. It realizes the circumferential rotation adjustment of the hub's inspection position and improves the inspection efficiency.

[0034] A bidirectional lead screw 17 is movably installed inside the adjustment frame 18. A second servo motor 14 is provided on the side wall of the adjustment frame 18. The second servo motor 14 plays a power driving role, and the output end of the second servo motor 14 is connected to the bidirectional lead screw 17.

[0035] Two sets of threaded sleeves 16 are fitted on the surface of the bidirectional lead screw 17, and the threaded sleeves 16 are threadedly connected to the bidirectional lead screw 17. The bottom end of each threaded sleeve 16 is provided with a lower ultrasonic probe 15.

[0036] A first servo motor 2 is provided on the top of the inspection platform 1 on the other side of the placement seat 4. The first servo motor 2 plays the role of power drive. A drive shaft 6 is provided at the output end of the first servo motor 2. A movable shaft 8 is provided at the bottom end of the placement seat 4, and the pulley assembly 7 extends to the surface of the movable shaft 8. The movable shaft 8 is movably connected to the inspection platform 1.

[0037] A PLC controller 3 is installed on the top of the maintenance platform 1 on one side of the first servo motor 2, and the output terminal of the PLC controller 3 is electrically connected to the first cylinder 9, the second servo motor 14, the side ultrasonic probe 13, and the input terminal of the first servo motor 2.

[0038] During the rotation of the wheel hub, the second servo motor 14 can be turned on, which drives the bidirectional lead screw 17 to rotate. With the bidirectional lead screw 17 and the threaded sleeve 16 connected by threads, the bidirectional lead screw 17 drives the two sets of threaded sleeves 16 to move towards or away from each other. The threaded sleeves 16 drive the ultrasonic probes 15 to move closer or further away from each other, thereby adjusting the inspection position of the ultrasonic probes 15 laterally. This facilitates a more comprehensive flaw detection and inspection of the bottom of the wheel hub, avoids any omissions in the inspection, and allows for flexible adjustment of the inspection position, thus improving the overall flaw detection and inspection effect of the wheel hub.

[0039] The working principle of the technical solution provided by this utility model is as follows: With the blank side of the wheel hub facing upward, the center hole of the wheel hub is fitted onto the surface of the limiting post 24. Under the weight of the wheel hub itself, the wheel hub drives the sliding sleeve 23 to move downward on the surface of the limiting post 24, and the sliding sleeve 23 compresses the spring 25. The sliding sleeve 23 drives the sliding rod 26 to slide inside the placement seat 4. The sliding rod 26 drives the clamping arm 21 to rotate around the hinge shaft 20. The clamping arm 21 drives the clamping block 22 to rotate. The three sets of clamping blocks 22 rotate synchronously and contact the outer wall of the wheel hub to clamp and fix the wheel hub. When it is necessary to remove the wheel hub, the wheel hub is moved upward. Under the elastic cooperation of the spring 25, the spring 25 drives the sliding sleeve 23 to return to its original position. Under the linkage cooperation of the sliding rod 26 and the clamping arm 21, the clamping arm 21 drives the clamping block 22 away from the wheel hub, and the wheel hub can be removed. The first cylinder 9 drives the first push arm 11 to move downward, and the first push arm 11 drives the side ultrasonic probe 13. The lower ultrasonic probe 15 moves to the inside of the hub, where the side ultrasonic probe 13 and the lower ultrasonic probe 15 respectively perform flaw detection and repair on the inner wall and bottom of the hub. The first servo motor 2 drives the pulley assembly 7 to move via the drive shaft 6, which in turn drives the movable shaft 8 to rotate. The movable shaft 8 then drives the mounting seat 4 and the hub to rotate, allowing the side ultrasonic probe 13 and the lower ultrasonic probe 15 to perform flaw detection and repair on different positions on the inner wall and bottom of the hub, improving the efficiency of flaw detection and repair and preparing for subsequent hub repair. During the hub rotation, the second servo motor 14 drives the bidirectional lead screw 17 to rotate, which in turn drives the two sets of threaded sleeves 16 to move towards or away from each other. The threaded sleeves 16 cause the lower ultrasonic probe 15 to move closer or further away from each other, adjusting the inspection position of the lower ultrasonic probe 15 laterally. This facilitates a more comprehensive flaw detection and repair of the bottom of the hub, avoiding any omissions in the inspection.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
