Description

Technical Field

[0001] This invention belongs to the field of bushing error prevention and detection technology, and particularly relates to an intelligent error prevention and detection device and method for automotive stabilizer bar bushings. Background Technology

[0002] In the field of automotive parts manufacturing and testing, the installation accuracy of automotive stabilizer bar bushings directly affects the driving stability of a vehicle.

[0003] Currently, there are significant deficiencies in the inspection of automotive stabilizer bar bushings, making it difficult to meet the requirements for accurate testing: First, the stabilizer bar fixing mechanism lacks self-adjusting capability, failing to flexibly adapt to stabilizer bars of different lengths. Furthermore, it cannot adjust the clamping angle according to the actual tilt angle of the stabilizer bar arm and body, requiring manual replacement of corresponding clamping components. This operation is cumbersome and has low positioning accuracy, easily leading to stabilizer bar displacement due to clamping deviations, affecting subsequent test results. Second, the bushing inspection process lacks comprehensive testing capabilities, failing to accurately move the testing components to the testing position, struggling to adapt to bushing openings of different sizes, and unable to simultaneously and accurately test the bushing installation position and orientation. It also has blind spots, unable to test bushing openings located on the other side of the stabilizer bar. Third, existing testing equipment cannot accurately measure the distance between the bushing outer wall and the stabilizer bar wall using the stabilizer bar outer wall as a reference. This makes it difficult to determine whether the bushing installation model is correct and whether the bushing is deformed, and it cannot achieve comprehensive testing of different positions around the entire circumference of the bushing, easily leaving installation defects. Simultaneously, the entire testing process requires frequent manual intervention, resulting in low testing efficiency and high workload for workers.

[0014] A method for intelligent error-proofing detection of automotive stabilizer bar bushings includes the following steps: S1: Car stabilizer bar positioning and clamping; The operator places the car stabilizer bar inside the openings of the two clamping plates, ensuring that the rocker arms on both sides of the car stabilizer bar face upwards, completing the initial placement and positioning; Control the first electric slide rail to start, driving the two auxiliary sliding plates to move, so that the clamping plates correspond to the area of ​​the car stabilizer bar's outer wall where the bushing is not installed; Control the second motor to start, driving the third electric telescopic rod and the second clamping plate to rotate, so that the tilt angle of the second clamping plate matches the tilt angle of the car stabilizer bar's outer wall, and then control the third electric telescopic rod to start, driving the second clamping plate to clamp the car stabilizer bar body; Subsequently, Control the first motor to start, driving the first round rod, support rod and fixing frame to rotate, so that the tilt angle of the first clamping plate inside the fixing frame is consistent with that of the rocker arm, Control the first electric slide rail and the first electric telescopic rod to start together, so that the fixing frame covers the rocker arm, and then Control the second electric telescopic rod to start, driving the first clamping plate to clamp the rocker arm, completing the full fixation of the car stabilizer bar.

[0015] S2: Bushing installation position and orientation detection; Activate the orientation detection component to control the second, third, and fourth electric slide rails and telescopic rods to start in tandem, moving the arc-shaped plate to fit the side of the vehicle stabilizer bar to be tested and completely covering the area; Control the fourth electric slide rail to start, moving the fourth sliding plate so that one end of the mounting rod corresponds to the side of the bushing installation opening; Control the fourth electric telescopic rod to retract, making the connecting block in close contact with the outer wall of the vehicle stabilizer bar; Control the fifth electric slide rail to start, adjusting the distance between the two fifth sliding plates so that the distance between the two first pressure sensors is slightly larger than the bushing installation opening size; Then Control the fifth electric slide rail to start. The telescopic rod is activated, and the distance between the second and first pressure sensors is adjusted to match the depth of the bushing installation opening. The second electric slide rail is slowly activated, driving the connecting block to move towards the inner wall of the bushing installation opening. The bushing installation position and orientation are determined by whether the first and second pressure sensors simultaneously detect pressure signals. After completing one test, the direction detection component is reset, and the above steps are repeated to test other bushings. When it is necessary to test a bushing opening located on the other side of the stabilizer rod, the third and fourth motors are controlled to drive the arc plate and connecting rod to rotate 180 degrees respectively, and then the above steps are repeated for testing.

[0016] S3: Bushing installation model and deformation detection; after completing the detection of all bushing positions and orientations, control the orientation detection component to reset and start the distance detection component; control the second electric slide rail, the third electric slide rail, and the fourth electric telescopic rod to start in tandem, causing the arc plate to cover the vehicle stabilizer bar again, so that the guide plate corresponds to the side of the bushing to be tested; control the sixth electric slide rail to start, adjust the distance between the fourth pressure sensor and the third pressure sensor to match the preset distance between the standard model bushing and the outer wall of the stabilizer bar, control the fourth electric telescopic rod to retract, so that the third pressure sensor contacts the outer wall of the stabilizer bar; through the third pressure sensor and... The fourth pressure sensor detects a pressure signal simultaneously to determine the bushing model and whether there is deformation at this location. After completing one test, the fourth electric telescopic rod is extended, and the fourth electric slide rail is activated to move the sensor along the outer wall of the bushing, detecting different positions on the same side of the bushing. After completing half of the bushing test, the third electric slide rail is moved upward to move the fixed plate, and the third and fourth motors are moved 180 degrees to rotate the arc plate and connecting rod. The other side of the bushing is then tested following the same steps. After completing one bushing test, the distance detection component is reset, and the above steps are repeated to test other bushings, achieving all-round error-proof detection.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: Two first electric slide rails can flexibly move the first slide plate and auxiliary slide plate to adapt to the positioning requirements of stabilizer bars of different lengths. The first motor drives the first round rod, support rod, and fixing frame to rotate, and can adaptively adjust the tilt angle of the fixing frame according to the actual tilt angle of the stabilizer bar rocker arm, without the need to replace clamping parts. The second motor drives the third electric telescopic rod and the second clamping plate to rotate, allowing the second clamping plate to adapt to the tilt angle of the stabilizer bar body, ensuring a good clamping fit. The first, second, and third electric telescopic rods can flexibly adjust the clamping height and clamping force. Through the cooperation of the first and second clamping plates, the stabilizer bar rocker arm and the bar body are firmly clamped respectively, preventing the stabilizer bar from shifting during the testing process. The entire fixing process does not require frequent manual intervention, has strong adaptive adjustment capabilities, improves the stability and positioning accuracy of clamping, and eliminates the step of replacing clamping parts, significantly improving the preparation efficiency before testing and reducing the workload of operators. Through the coordinated action of the second, third, and fourth electric slide rails, the arc-shaped plate and detection sensors can be precisely moved to the position of the bushing to be tested. The arc-shaped plate completely covers the area to be tested, ensuring no blind spots in the detection. The fifth electric slide rail adjusts the spacing of the first pressure sensor, and the fifth electric telescopic rod adjusts the spacing between the second and first pressure sensors to accommodate bushing openings of different sizes. By checking whether the first and second pressure sensors detect pressure signals simultaneously, it is possible to accurately determine whether the bushing installation position is offset and whether the installation direction is correct. At the same time, the third and fourth motors can rotate the arc-shaped plate and connecting rod 180 degrees to detect bushing openings located on the other side of the stabilizing rod, further avoiding blind spots in the detection. The distance detection component uses the contact between the third pressure sensor and the outer wall of the vehicle stabilizer bar as a detection reference. The sixth electric slide rail adjusts the distance between the fourth and third pressure sensors to adapt to the distance requirements of the standard bushing and stabilizer bar. By checking whether the two sensors detect pressure signals simultaneously, it can accurately determine whether the bushing installation model is correct and whether the bushing is deformed. The fourth electric slide rail can drive the sensor to move along the outer wall of the bushing. Combined with the 180-degree rotation of the arc plate, it can realize the detection of different positions around the entire circumference of the bushing, ensuring comprehensive detection and effectively avoiding installation problems caused by bushing model mismatch or deformation, thus ensuring the stability of the vehicle stabilizer bar.

[0030] S2: Bushing installation position and orientation detection; Activate orientation detection component 4 to control the second electric slide rail 41, the third electric slide rail 44, and the fourth electric telescopic rod 46 to start in tandem, moving the arc plate 410 to fit the side of the bushing to be tested on the vehicle stabilizer bar and completely covering the area; Control the fourth electric slide rail 411 to start, moving the fourth sliding plate 412 so that one end of the mounting rod 416 corresponds to the side of the bushing installation opening; Control the fourth electric telescopic rod 46 to retract, making the connecting block 417 in close contact with the outer wall of the vehicle stabilizer bar; Control the fifth electric slide rail 419 to start, adjusting the distance between the two fifth sliding plates 420 so that the distance between the two first pressure sensors 421 is slightly larger than the bushing installation opening size; Then Control the fifth electric slide rail 419 to start, adjusting the distance between the two fifth sliding plates 420 so that the distance between the two first pressure sensors 421 is slightly larger than the bushing installation opening size; The telescopic rod 422 is activated, and the distance between the second pressure sensor 423 and the first pressure sensor 421 is adjusted to match the depth of the bushing installation opening. The second electric slide rail 41 is slowly activated, driving the connecting block 417 to move towards the inner wall of the bushing installation opening. The bushing installation position and direction are determined by whether the first pressure sensor 421 and the second pressure sensor 423 detect pressure signals simultaneously. After completing one test, the direction detection component 4 is reset, and the above steps are repeated to test other bushings. When it is necessary to test the bushing opening located on the other side of the stabilizer rod, the third motor 49 and the fourth motor 415 are controlled to drive the arc plate 410 and the connecting rod 414 to rotate 180 degrees respectively, and then the above steps are repeated for testing.

[0031] S3: Bushing installation model and deformation detection; after completing the detection of all bushing positions and directions, control the direction detection component 4 to reset and start the distance detection component 5; control the second electric slide rail 41, the third electric slide rail 44 and the fourth electric telescopic rod 46 to start in tandem, causing the arc plate 410 to cover the vehicle stabilizer bar again, so that the guide plate 56 corresponds to the side of the bushing to be tested; control the sixth electric slide rail 54 to start, adjust the distance between the fourth pressure sensor 57 and the third pressure sensor 52 to be consistent with the preset distance between the standard model bushing and the outer wall of the stabilizer bar, control the fourth electric telescopic rod 46 to retract, so that the third pressure sensor 52 contacts the outer wall of the stabilizer bar; through the third pressure sensor 52 The system checks whether the pressure signal is detected simultaneously with the fourth pressure sensor 57 to determine the bushing model and whether there is deformation at that location. After completing one test, it controls the fourth electric telescopic rod 46 to extend and the fourth electric slide rail 411 to start, driving the sensor to move along the outer wall of the bushing to test different positions on the same side of the bushing. After completing half of the bushing test, it controls the third electric slide rail 44 to move the fixed plate 51 upward, and controls the third motor 49 and the fourth motor 415 to rotate the arc plate 410 and the connecting rod 414 180 degrees. Then, it checks the other side of the bushing according to the above steps. After completing one bushing test, it controls the distance detection component 5 to reset and repeats the above steps to test other bushings, achieving all-round error-proof detection.

[0032] The operating principle of the present invention is described as follows: In this invention, when it is necessary to check the installation position of the car stabilizer bar bushing and whether there is an error in the bushing model during installation, the operator first places the car stabilizer bar inside the opening of the two clamping plates 312, ensuring that the rocker arms on both sides of the car stabilizer bar face upwards, completing the initial placement and positioning of the workpiece to be tested. Then, the first electric slide rail 31 is started, and the first electric slide rail 31 drives the two auxiliary slide plates 311 slidably connected to its top side wall to move synchronously until the two clamping plates 312 accurately correspond to the area of ​​the outer wall of the car stabilizer bar where the bushing is not installed, realizing the preliminary positioning of the test reference and laying the foundation for subsequent stable clamping. After positioning is completed, the second motor 314 is started. The output end of the second motor 314 drives the third electric telescopic rod 315 and the second clamping plate 316 to rotate synchronously. The tilt angle of the second clamping plate 316 is adjusted so that the tilt angle of the second clamping plate 316 is completely matched with the tilt angle of the outer wall of the car stabilizer bar at the corresponding position. This ensures the fit during clamping and avoids the positioning of the stabilizer bar shifting due to clamping angle deviation, which would affect the subsequent detection accuracy. After the angle is adjusted to the correct position, the third electric telescopic rod 315 is started. The telescopic end of the third electric telescopic rod 315 drives the second clamping plate 316 to move towards the wall of the car stabilizer bar. The two symmetrically arranged second clamping plates 316 are used to firmly clamp the body of the car stabilizer bar, thereby fixing and limiting the workpiece to be tested and preventing the stabilizer bar from shifting during the testing process. After the vehicle stabilizer bar is fixed, the first motor 36 is started. The output end of the first motor 36 passes through the side wall of the first U-plate 34 and is fixedly connected to the first round rod 35, driving the first round rod 35 to rotate synchronously. During the rotation of the first round rod 35, the support rod 37 and the fixing frame 38 fixedly connected to its wall also rotate together, adjusting the tilt angle of the fixing frame 38 in real time. When the tilt angle of the first clamping plate 310 inside the fixing frame 38 is completely consistent with the tilt angle of the rocker arms on both sides of the vehicle stabilizer bar, the first motor 36 is turned off, stopping the angle adjustment. Subsequently, the first electric slide rail 31 and the first electric telescopic rod 33 are started in tandem. The first electric slide rail 31 drives the first slide plate 32 to move, and the first electric telescopic rod 33 drives the fixed frame 38 to rise and fall synchronously, so that the fixed frame 38 accurately covers the rocker arms on both sides of the car stabilizer bar. Then, the second electric telescopic rod 39 is activated. The telescopic end of the second electric telescopic rod 39 drives the first clamping plate 310 to move. The first clamping plate 310 is used to firmly clamp the rocker arms, completing the full fixation of the car stabilizer bar. This fixing method can be adaptively adjusted according to the actual position and tilt angle of the rocker arms, without the need for staff to replace the corresponding fixing parts, effectively improving the testing efficiency, while ensuring the stability of the fixation, and providing a reliable positioning benchmark for subsequent testing. After the vehicle stabilizer bar is fixed, the direction detection component 4 is activated to start detecting the bushing installation direction and position. Specifically, the second electric slide rail 41, the third electric slide rail 44 and the fourth electric telescopic rod 46 are controlled to start in concert. The second electric slide rail 41 drives the second sliding plate 42 at its top to move, the third electric slide rail 44 drives the third sliding plate 45 to move, and then drives the fourth electric telescopic rod 46 to move synchronously. At the same time, the telescopic end of the fourth electric telescopic rod 46 drives the arc plate 410 to move until the arc plate 410 precisely fits the side of the vehicle stabilizer bar where the bushing to be detected needs to be, and the arc plate 410 completely covers the area of ​​the vehicle stabilizer bar, providing a closed and accurate detection space for subsequent sensor detection. After the arc plate 410 is positioned, the fourth electric slide rail 411 is activated. The fourth electric slide rail 411 drives the fourth sliding plate 412, which is slidably connected to its side wall, to move, so that one end of the mounting rod 416 is precisely aligned with one side of the bushing mounting opening, ensuring that the detection sensor can be accurately aligned with the detection part. Then, the fourth electric telescopic rod 46 is retracted, driving the connecting block 417 to move towards the vehicle stabilizer bar until the side wall of the connecting block 417 is in close contact with the outer wall of the vehicle stabilizer bar, thereby achieving recalibration of the detection benchmark and avoiding detection errors caused by the detection position offset. After calibration, the fifth electric slide rail 419 is activated, which moves the fifth slide plate 420 on its side wall. The distance between the two fifth slide plates 420 is adjusted so that the distance between the first pressure sensors 421 fixedly connected to the side walls of the two fifth slide plates 420 is slightly larger than the opening size of the corresponding bushing side installation opening. This ensures that the first pressure sensor 421 can be smoothly inserted into the bushing opening without interference. Then, the fifth electric telescopic rod 422 is activated, and the telescopic end of the fifth electric telescopic rod 422 moves the second pressure sensor 423. The distance between the detection end of the second pressure sensor 423 and the detection end of the first pressure sensor 421 is adjusted so that it is completely matched with the depth of the corresponding bushing side installation opening, ensuring the comprehensiveness of the detection. After the above adjustments are completed, the second electric slide rail 41 is slowly started, driving the second slide plate 42 and connecting block 417 to move towards the inner wall of the bushing installation opening on one side to detect the bushing installation position and opening direction. When the two first pressure sensors 421 simultaneously contact the side wall of the bushing opening and detect pressure signals, and the second pressure sensor 423 simultaneously contacts the bottom of the bushing installation opening and detects pressure signals, it indicates that the bushing installation opening position, opening size, and installation direction at this position meet the requirements, that is, the bushing installation position is correct. If the first pressure sensor 421 and the second pressure sensor 423 do not simultaneously detect pressure signals, or only one sensor detects a pressure signal, it indicates that there is a deviation in the bushing installation position or an incorrect installation direction, thus completing the error prevention detection of the bushing installation position and direction. After completing the direction and position detection of one bushing, the components of the direction detection assembly 4 are restored to their initial positions. Following the same steps, the installation positions and directions of other bushings on the vehicle stabilizer bar are detected one by one. When it is necessary to detect the bushing installation opening located on the other side of the vehicle stabilizer bar, the third motor 49 is started. The output of the third motor 49 drives the side rod 48 and the arc plate 410 to rotate synchronously by 180 degrees and then stops. Then, the fourth motor 415 is started. The output of the fourth motor 415 drives the connecting rod 414 and the mounting rod 416 to rotate synchronously by 180 degrees and then stops. At this time, the position of the arc plate 410 and the detection sensor corresponds precisely to the position on the other side of the bushing opening. By following the above detection steps, the installation position and direction detection when the bushing opening is located on the other side of the vehicle stabilizer bar can be completed, realizing all-round detection of the bushing installation position and avoiding blind spots. After completing the detection of all bushing installation positions and directions, the components of the direction detection assembly 4 are restored to their initial positions. Then, the distance detection assembly 5 is activated to detect the installation type of the bushing and whether the bushing itself has any deformation. The specific operation is as follows: the second electric slide rail 41, the third electric slide rail 44 and the fourth electric telescopic rod 46 are activated in coordination to drive the second sliding plate 42, the third sliding plate 45 and the arc plate 410 under the fixed plate 51 to move, so that the arc plate 410 completely covers the vehicle stabilizer bar again, and the guide plate 56 on one side of the fixed plate 51 is precisely aligned with the side of the bushing to be detected, ensuring that the detection sensor can accurately align with the gap area between the bushing and the stabilizer bar. After positioning, the sixth electric slide rail 54 is activated, which drives the sixth sliding plate 55 on its side wall to move, thereby driving the guide plate 56 and the fourth pressure sensor 57 to move synchronously. The distance between the detection end of the fourth pressure sensor 57 and the detection end of the third pressure sensor 52 is adjusted so that it is completely consistent with the preset distance between the outer wall of the car stabilizer bar and the outer wall of the standard model bushing. This preset distance is the core benchmark for detecting whether the bushing model is correct. After adjustment, the fourth electric telescopic rod 46 is retracted, which drives the fixed plate 51 to move towards the car stabilizer bar until the detection end of the third pressure sensor 52 is in close contact with the outer wall of the car stabilizer bar and detects a pressure signal. If the detection end of the fourth pressure sensor 57 simultaneously contacts the outer wall of the bushing and detects a pressure signal, it indicates that the installation model of the bushing meets the requirements and there is no obvious deformation of the bushing at this point; if the third pressure sensor 52 detects a pressure signal but the fourth pressure sensor 57 does not detect a pressure signal, or the two detect pressure signals at different times, it indicates that the installation model of the bushing does not meet the requirements, or there is deformation of the bushing at this point, resulting in an abnormal distance between the outer wall of the bushing and the outer wall of the stabilizer bar. After completing the gap detection at one position of the bushing, the fourth electric telescopic rod 46 is extended, causing the third pressure sensor 52 to separate from the outer wall of the vehicle stabilizer bar. Then, the fourth electric slide rail 411 is activated, and the fourth electric slide rail 411 drives the fourth slide plate 412 and the fixing plate 51 to move synchronously, thereby driving the third pressure sensor 52 and the fourth pressure sensor 57 to move along the outer wall of the bushing, so as to realize the comprehensive detection of the gap between the outer wall of the bushing at different positions on the same side and the outer wall of the vehicle stabilizer bar. After the gap between half of the bushing's outer wall and the vehicle's stabilizer bar is detected, the third electric slide rail 44 is activated, driving the third slide plate 45 and the fixing plate 51 to move upwards, avoiding the bushing and stabilizer bar. Then, the third motor 49 and the fourth motor 415 above the fixing plate 51 are activated simultaneously, driving the arc plate 410 and the connecting rod 414 to rotate 180 degrees synchronously and then stop, so that the arc plate 410 completely covers the other half of the vehicle's stabilizer bar's outer wall, and the fixing plate 51 and the detection sensor accurately correspond to the other side of the bushing. After that, following the above gap detection steps, the gap between the other half of the bushing's outer wall and the vehicle's stabilizer bar's outer wall can be detected, and it can be determined whether there is a model mismatch or deformation problem on the other side of the bushing. After completing the model and deformation detection of one bushing, the components of the control distance detection assembly 5 are restored to their initial positions. Following the same steps, other bushings on the vehicle stabilizer bar are then inspected one by one. Through this series of coordinated actions, comprehensive intelligent error-proof detection of the installation position, installation direction, installation model, and bushing deformation of the vehicle stabilizer bar bushings is achieved, ensuring that the bushings can be used stably after installation.
