Description

Technical Field

[0001] This invention relates to the field of online intelligent detection technology for wheel hub bolt hole blockage, specifically to an online intelligent detection device for wheel hub bolt hole blockage. Background Technology

[0002] Wheel hubs, also known as wheel rims, undergo different surface treatment processes depending on the characteristics and needs of different vehicle models. These can be broadly categorized into two types: baking paint and electroplating. To ensure good heat dissipation, baking paint is the most common process, involving spraying paint followed by electroplating. This method is relatively economical, produces vibrant colors, and maintains the color for a long time; even after the vehicle is scrapped, the wheel hub's color remains unchanged. To prevent paint from contaminating the wheel hub bolt holes during painting and affecting later assembly, protective plugs are used to seal the bolt holes before painting. These plugs are then manually removed after painting. However, omissions are inevitable during disassembly. Without inspection, this can significantly impact later vehicle assembly. Traditional wheel hub bolt hole inspection methods typically rely on manual inspection or simple mechanical tools. These methods suffer from low efficiency, excessive manual intervention, and insufficient accuracy, failing to meet the high precision and efficiency requirements of modern production lines. With the development of intelligent manufacturing technology, automated inspection systems based on sensors, industrial cameras, and image recognition technology are gradually becoming important means to improve production efficiency and ensure product quality.

[0003] A Chinese patent with publication number CN115753767A includes a bracket on which an industrial camera is mounted. The industrial camera is located above a conveyor line and is used to acquire black-and-white images of a wheel hub. The industrial camera is electrically connected to a controller, which can control the industrial camera to take pictures. The controller includes an image analysis module, a storage module, and an input module. The image analysis module can determine whether there is a deviation in the central angle of all two adjacent bolt holes in the image of the wheel hub. The storage module can store the qualified central angle values ​​of the wheel hub.

[0004] When the above-mentioned device is in use, it can take pictures of the wheel hub and measure and judge whether the central angle of all two adjacent bolt holes on the image of the wheel hub under test is qualified through the cooperation of industrial camera, controller and detection sensor. However, in actual use, due to the real-time change of the speed of the conveyor line in moving the wheel hub, the wheel hub is prone to shift from the position of the industrial camera under the action of inertia, which affects the detection efficiency of the industrial camera on the wheel hub bolt holes. Therefore, it is difficult to transport the wheel hub to the designated position in a step-by-step manner. Summary of the Invention

[0005] The purpose of this invention is to provide an online intelligent detection device for wheel hub bolt hole blockage, which has the advantage of step-by-step conveying of the wheel hub to a designated position, thus solving the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an online intelligent detection device for wheel hub bolt hole blockage, comprising an inverted U-shaped frame fixedly supported on the ground, wherein a moving rod is horizontally connected and penetrated on both sides of the inverted U-shaped frame near the top, a fixed block is fixedly connected and penetrated on the moving rod, and a second spring is fixedly connected on one side of the fixed block and the opposite surface of the inverted U-shaped frame to guide the moving rod to reset movement, a lifting rod is vertically connected and penetrated on the fixed block, a fixed plate is fixedly connected to the end of the fixed block, and multiple evenly placed columnar rods are fixedly connected on both sides of the fixed plate, each columnar rod is fixedly connected to the end of a lifting plate to support the wheel hub, and a first spring is fixedly connected on the opposite surface of each lifting plate and the fixed plate to guide the lifting plate to reset movement, and the inverted U-shaped frame is provided with a conveying mechanism for step-by-step movement of the wheel hub by actuating the lifting plate.

[0007] Preferably, the conveying mechanism includes a rotating shaft driven by a power mechanism that is symmetrically connected to both sides of the inverted U-shaped frame near the bottom and rotates on a fixed axis. A cylindrical cam that pushes a moving rod to move horizontally and reciprocally is coaxially fixed to one end of the rotating shaft away from the second spring. A support block is fixedly connected to the outer contour of the moving rod near the cylindrical cam. A ball bearing that rolls in contact with the surface of the cylindrical cam is rotatably connected to the bottom of the support block.

[0008] Preferably, the rotating shaft is coaxially fixed to the side near the fixed block with a transmission cam that pushes the lifting rod to move up and down, and the bottom end of the lifting rod is fixedly connected to a support plate that is in movable contact with the surface of the transmission cam.

[0009] Preferably, the cylindrical rod is provided with a clamping mechanism for fixing the wheel hub. The clamping mechanism includes connecting blocks fixedly connected to the ends of the cylindrical rod. Each connecting block is connected to a movable rod that is horizontally movable. Arc-shaped clamping plates for clamping the wheel hub are fixedly connected to the opposite ends of the movable rods on both sides.

[0010] Preferably, the end of each movable rod away from the arc-shaped clamp is rotatably connected to an adjusting rod via a pin, and the end of each adjusting rod away from the movable rod is rotatably connected to the lifting plate on the adjacent side via a pin.

[0011] Preferably, the inverted U-shaped frame has a movable groove on the side away from the cylindrical cam. An L-shaped frame is connected to the inner wall of the movable groove for lifting and moving. An industrial camera for capturing images of the wheel hub bolt holes is fixedly connected to the end of the L-shaped frame. Detection sensors for detecting the wheel hub position are fixedly connected to both sides of the L-shaped frame near the industrial camera. A controller that is electrically connected to the industrial camera and detection sensors is fixedly connected to one side of the L-shaped frame.

[0012] Preferably, a second connecting seat is fixedly connected to one end of the movable rod near the L-shaped frame. A support rod for pushing the L-shaped frame to move up and down is rotatably connected to the second connecting seat via a pin. A first connecting seat is fixedly connected to one side of the L-shaped frame near the bottom, and the end of the support rod away from the second connecting seat is rotatably connected to the first connecting seat via a pin.

[0013] Preferably, the L-shaped frame is provided with a feeding mechanism for automatically feeding the wheel hub. The feeding mechanism includes a receiving plate fixedly connected to one side of the L-shaped frame, an electric push rod electrically connected to the controller at the end of the receiving plate away from the L-shaped frame, a push block for moving the wheel hub to feed the material fixedly connected to the output shaft at the end of the electric push rod, and an L-shaped rod fixedly connected at a symmetrical position on the side of the L-shaped frame away from the receiving plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The conveying mechanism, through the cooperation of the rotating shaft and the cylindrical cam, realizes the stepping movement of the wheel hub. The stepping mechanism ensures that every movement of the wheel hub in the production line is accurate and error-free, avoiding misalignment, deviation or missed inspection that may occur in manual operation. Through mechanized conveying, the equipment can maintain efficient and stable operation in high-speed production environment, which greatly improves production efficiency and reduces errors and risks caused by human factors. Especially in large-scale production, this mechanism can ensure that the wheel hub automatically moves to the inspection position according to the predetermined path, effectively improving work efficiency and inspection accuracy.

[0015] Second, the movable and adjusting rods on the column rod enable precise clamping of the wheel hub. The movable and adjusting rods work together to allow the arc-shaped clamping plate to automatically adjust the clamping force according to the size of the wheel hub, ensuring that the wheel hub will not shift or slide due to external forces during transportation, preventing the wheel hub from falling or being damaged during transportation. This clamping system not only improves the stability of the wheel hub during transportation, but also provides safer and more reliable support for the entire inspection process, avoiding accidents on the production line and reducing the risk of equipment damage and personnel injury.

[0016] Third, by using an L-shaped frame in conjunction with an industrial camera and a detection sensor, this invention enables intelligent detection of blocked wheel hub bolt holes. The lifting and moving function of the L-shaped frame allows the camera and sensor to be accurately aligned with the wheel hub, ensuring that the detection of each bolt hole is not off-position. The detection sensor senses the state of the wheel hub in real time and transmits the data to the controller, which then activates the industrial camera to photograph the wheel hub. This intelligent detection system not only improves the accuracy of detection but also significantly enhances the automation level of the production line, reduces manual intervention, and ensures that the detection results of each wheel hub accurately reflect the actual situation, effectively avoiding quality problems caused by human error.

[0017] Fourth, the L-shaped frame is equipped with an automatic unloading mechanism, including an electric push rod and a receiving plate. After the wheel hub completes inspection, the electric push rod automatically drives the push block to move the wheel hub to the receiving plate, realizing automated unloading. This function avoids the tedious operation of manual unloading, reduces the intensity of manual labor, and improves the overall efficiency of the production line. The automatic unloading system allows each wheel hub to quickly enter the next stage of processing or assembly after inspection, ensuring the continuity and efficiency of wheel hub processing. In addition, automatic unloading also reduces wheel hub damage or quality problems caused by manual handling, ensuring the smooth operation of the entire production process.

[0018] The combined use of the above structures solves the problem that in the actual use of existing devices, due to the real-time change in the speed of the conveyor line moving the hub, the hub is prone to shift from the position of the industrial camera under the action of inertia, which affects the detection efficiency of the industrial camera on the hub bolt holes and makes it difficult to transport the hub to the designated position in a step-by-step manner.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] Example 1: Please refer to Figures 1 to 8 This invention provides a technical solution: an online intelligent detection device for wheel hub bolt hole blockage, comprising an inverted U-shaped frame 1 fixedly supported on the ground, with a moving rod 2 horizontally connected to symmetrical positions near the top of the inverted U-shaped frame 1, a fixed block 3 fixedly connected to the moving rod 2, and a second spring 8 fixedly connected to one side of the fixed block 3 opposite to the inverted U-shaped frame 1 to guide the moving rod 2 to reset movement, a lifting rod 30 fixedly connected to the fixed block 3 to lift and lower movement, a fixed plate 4 fixedly connected to the end of the fixed block 3, and multiple evenly placed columnar rods 5 fixedly connected to symmetrical positions on both sides of the fixed plate 4, a lifting plate 6 for supporting the wheel hub fixedly connected to the end of each columnar rod 5, and a first spring 7 for guiding the lifting plate 6 to reset movement fixedly connected to the opposite surface of each lifting plate 6 and the fixed plate 4, and a conveying mechanism for step-by-step movement of the wheel hub by actuating the lifting plate 6 on the inverted U-shaped frame 1.

[0022] In use, by setting up an inverted U-shaped frame 1, which is fixedly supported on the ground, the stability of the detection device is improved. First, the wheel hubs are evenly placed on the inverted U-shaped frame 1 for subsequent movement. A moving rod 2 is set on the inverted U-shaped frame 1, and a fixed block 3 is set on the moving rod 2. The fixed block 3 is fixedly supported on the moving rod 2, allowing the moving rod 2 to drive the fixed block 3 to move horizontally on the inverted U-shaped frame 1. A lifting rod 30 is set on the fixed block 3, and a fixed plate 4 is set on the lifting rod 30. The fixed plate 4 is fixedly supported at the end of the lifting rod 30, allowing the lifting rod 30 to support the fixed plate 4. Simultaneously, the lifting rod 30... The fixed plate 4 is moved up and down on the fixed block 3. The column rod 5 on the fixed plate 4 is fixedly supported on the fixed plate 4. The lifting plate 6 on the column rod 5 and the first spring 7 on the lifting plate 6 allow the lifting plate 6 to move up and down on the column rod 5. The first spring 7 supports the position of the lifting plate 6. The second spring 8 on the fixed block 3 supports the position of the fixed block 3. The conveying mechanism on the inverted U-shaped frame 1 can lift the wheel hub to be inspected on the inverted U-shaped frame 1 through the lifting plate 6 and move it step by step to facilitate the subsequent inspection of the bolt holes of the wheel hub.

[0023] Example 2: Building upon Example 1, the following is a further step: The conveying mechanism includes a U-shaped frame 1 with a rotating shaft 9 symmetrically connected to both sides near the bottom and driven by a power mechanism. A cylindrical cam 10 that pushes the moving rod 2 to move horizontally and reciprocally is coaxially fixed to one end of the rotating shaft 9 away from the second spring 8. A support block 11 is fixedly connected to the outer contour of the moving rod 2 near the cylindrical cam 10. A ball bearing 12 that rolls in contact with the surface of the cylindrical cam 10 is rotatably connected to the bottom of the support block 11.

[0024] The rotating shaft 9 is coaxially fixed to the side near the fixed block 3 with a transmission cam 14 that pushes the lifting rod 30 to move up and down, and the bottom end of the lifting rod 30 is fixedly connected to a support plate 13 that is in movable contact with the surface of the transmission cam 14.

[0025] In use, the rotating shaft 9 on the inverted U-shaped frame 1 is driven by a motor to rotate. The motor can drive the rotating shaft 9 to rotate on the inverted U-shaped frame 1. The cylindrical cam 10 on the rotating shaft 9 is coaxially fixed to the rotating shaft 9, so that the cylindrical cam 10 can rotate synchronously with the rotating shaft 9. The support block 11 on the moving rod 2 has a ball bearing 12 on it. As the ball bearing 12 rolls into contact with the surface of the cylindrical cam 10, the support block 11 pushes the moving rod 2 to move horizontally reciprocally under the action of the ball bearing 12 and the cylindrical cam 10. The transmission cam 14 on the rotating shaft 9 can rotate synchronously with the rotating shaft 9. The support plate 13 on the lifting rod 30 is in contact with the outer wheel of the transmission cam 14, so that the support plate 13 can push the fixed plate 4 to move up and down reciprocally under the action of the transmission cam 14.

[0026] like Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, when the end of the transmission cam 14 pushes the lifting rod 30 and the fixed plate 4 to move vertically upward, the lifting plate 6 moves upward under the action of the fixed plate 4 and contacts the wheel hub. Under the action of the wheel hub's gravity, the lifting plate 6 moves vertically closer to the fixed plate 4. The first spring 7 is compressed and contracted under the action of the lifting plate 6, which can buffer the wheel hub and avoid rigid contact causing wear to the wheel hub. When the lifting plate 6 moves to the limit position, the lifting plate 6 drives the wheel hub to lift upward under the action of the fixed plate 4, and the wheel hub disengages from the inverted U-shaped frame 1. At the same time, the support block 11 drives the fixed block 3 to move horizontally away from the cylindrical cam 10 under the action of the cylindrical cam 10. The second spring 8 is compressed and contracted under the action of the fixed block 3, so that the fixed plate 4 can move the wheel hub on the lifting plate 6 to the detection position.

[0027] When the fixed block 3 moves to its limit position away from the cylindrical cam 10, and the end of the transmission cam 14 rotates and disengages from the support plate 13, the lifting rod 30 moves downward in a vertical direction under the gravity of the fixed plate 4, causing the lifting plate 6 to move downward and place the hub on the detection position of the inverted U-shaped frame 1. As the lifting plate 6 disengages from the hub, the first spring 7 pushes the lifting plate 6 to move downward under the action of elasticity. At this time, the second spring 8 can push the fixed block 3 to move downward towards the cylindrical cam 10, so that the fixed plate 4 can drive the lifting plate 6 to move downward synchronously. Through the combined use of the above structures, the lifting plate 6 can move the hub on the inverted U-shaped frame 1 to the detection position in a step-by-step manner, so as to facilitate the subsequent detection of the hub bolt holes.

[0028] Example 3: Building upon Example 2, the following is a further step: The column rod 5 is provided with a clamping mechanism for fixing the wheel hub. The clamping mechanism includes connecting blocks 15 fixedly connected to the ends of the column rod 5. Each connecting block 15 is connected to a movable rod 16 that is horizontally movable. Arc-shaped clamping plates 17 for clamping the wheel hub are fixedly connected to the opposite ends of the movable rods 16 on both sides.

[0029] Each of the movable rods 16 has an adjusting rod 18 rotatably connected to the end away from the arc-shaped clamp 17 via a pin. The end of each adjusting rod 18 away from the movable rod 16 is rotatably connected to the lifting plate 6 on the adjacent side via a pin.

[0030] In use, the connecting block 15 on the column rod 5 is fixedly supported on the column rod 5. The movable rod 16 on the connecting block 15 moves horizontally on the connecting block 15. The adjusting rod 18 on the movable rod 16 allows both ends of the adjusting rod 18 to rotate and support on the movable rod 16 and the lifting plate 6 respectively. When the lifting plate 6 moves towards the column rod 5 under the weight of the wheel hub, the adjusting rod 18 can pull the movable rods 16 on both sides to move in opposite directions under the action of the lifting plate 6. The arc-shaped clamping plate 17 on the movable rod 16 moves in opposite directions under the action of the movable rod 16 to clamp and fix the wheel hub on the inverted U-shaped frame 1, ensuring the stability of the wheel hub during transportation and preventing accidental drop and damage to the wheel hub during transportation.

[0031] Example 4: Building upon Example 3, the following is a further improvement: A movable groove 101 is provided on the side of the inverted U-shaped frame 1 away from the cylindrical cam 10. An L-shaped frame 19 is connected to the inner wall of the movable groove 101 for lifting and moving. An industrial camera 20 for capturing images of the wheel hub bolt holes is fixedly connected to the end of the L-shaped frame 19. Detection sensors 21 for detecting the wheel hub position are fixedly connected to both sides of the L-shaped frame 19 near the industrial camera 20. A controller 31 that is electrically connected to the industrial camera 20 and the detection sensors 21 is fixedly connected to one side of the L-shaped frame 19.

[0032] The movable rod 2 is fixedly connected to a second connecting seat 24 at one end near the L-shaped frame 19. A support rod 25 for pushing the L-shaped frame 19 to move up and down is rotatably connected to the second connecting seat 24 via a pin. A first connecting seat 23 is fixedly connected to the side of the L-shaped frame 19 near the bottom, and the end of the support rod 25 away from the second connecting seat 24 is rotatably connected to the first connecting seat 23 via a pin.

[0033] In use, the L-shaped frame 19 is connected to the inner wall of the inverted U-shaped frame 1 by the movable groove 101 and the L-shaped frame 19 is provided on the movable groove 101. The industrial camera 20 and the detection sensor 21 are fixedly supported on the L-shaped frame 19 by the cylindrical cam 10. The first connecting seat 23 is provided on the L-shaped frame 19 and the second connecting seat 24 is provided on the moving rod 2. The first connecting seat 23 and the second connecting seat 24 are fixedly supported on the L-shaped frame 19 and the moving rod 2, respectively. The support rod 25 is provided on the first connecting seat 23 and the second connecting seat 24, and the two ends of the support rod 25 are rotatably supported on the first connecting seat 23 and the second connecting seat 24, respectively. With the horizontal reciprocating movement of the moving rod 2, the support rod 25 can pull the L-shaped frame 19 to move up and down reciprocally under the action of the moving rod 2.

[0034] When the lifting plate 6 moves the wheel hub stepwise to the detection position, the support rod 25, under the action of the moving rod 2, pulls the L-shaped frame 19 to move vertically closer to the wheel hub. This aligns the wheel hub with the positions of the industrial camera 20 and the detection sensor 21. Through the controller 31 mounted on the L-shaped frame 19, and with the industrial camera 20 and detection sensor 21 connected to the controller 31 via telecommunications, the detection sensor 21 detects the wheel hub and remotely sends a signal to the controller 31. Upon receiving the signal, the controller 31 activates the industrial camera 20 to capture an image of the wheel hub, enabling the industrial camera 20 to... The captured images are transmitted to the controller 31, which is equipped with a detection module and an alarm module. The detection module analyzes the captured images and identifies the location of the bolt holes. If a bolt hole is blocked, the blocked bolt hole will not be displayed. The detection module will recognize this abnormality. Blockage will cause a large deviation in the central angle between two adjacent bolt holes. The detection module determines whether there is a blockage by comparing the geometric relationship between adjacent holes. When the image processing unit detects a bolt hole blockage and confirms that the deviation exceeds a preset threshold, the system will issue a warning through the alarm module to prompt the operator.

[0035] Example 5: Building upon Example 4, the following is a further step: The L-shaped frame 19 is provided with a feeding mechanism for automatically feeding the wheel hub. The feeding mechanism includes a receiving plate 27 fixedly connected to one side of the L-shaped frame 19. An electric push rod 28 electrically connected to the controller 31 is fixedly connected to the end of the receiving plate 27 away from the L-shaped frame 19. A push block 29 for moving the wheel hub to feed is fixedly connected to the output shaft at the end of the electric push rod 28. An L-shaped rod 26 is fixedly connected to a symmetrical position on the side of the L-shaped frame 19 away from the receiving plate 27.

[0036] In use, the L-shaped rod 26 and receiving plate 27 on the L-shaped frame 19 can move up and down synchronously with the L-shaped frame 19. The electric push rod 28 on the L-shaped rod 26, with a push block 29 on it, fixes the electric push rod 28 to the L-shaped rod 26. When the L-shaped frame 19 moves the industrial camera 20 downwards to photograph the wheel hub, the L-shaped rod 26 and receiving plate 27 move to the bottom of the fixed plate 4 under the action of the L-shaped frame 19, preventing the fixed plate from... 4. The movement of the wheel hub is obstructed. When the L-shaped frame 19 moves upward to its limit distance, it causes the L-shaped frame 19 to move the L-shaped rod 26 and the receiving plate 27 to be on the same plane as the inverted U-shaped frame 1. At this time, the controller 31 completes the detection of the wheel hub, and the electric push rod 28 is electrically connected to the controller 31, which enables the controller 31 to start the electric push rod 28. Thus, the electric push rod 28 can push the detected wheel hub to the receiving plate 27 through the L-shaped frame 19, realizing the automatic unloading of the detected wheel hub.

[0037] Furthermore, the existing device can be used to transport the wheel hub to the designated position in a step-by-step manner during actual use, which improves the detection efficiency, is convenient to use, and is better than traditional products.

[0038] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the specification and drawings can be processed directly based on existing technical knowledge without any doubt. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0039] It is understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
