Description

Technical Field

[0001] This utility model belongs to the field of motor vehicle exhaust gas processor testing technology, specifically an exhaust gas processor testing fixture fixing device. Background Technology

[0002] Existing exhaust gas processor testing fixtures suffer from several technical drawbacks in practical applications: First, insufficient adaptability. Exhaust pipe diameters and shapes (circular, elliptical, etc.) vary significantly across different vehicle models. Traditional fixtures are mostly fixed-size or manually adjustable, with limited adjustment ranges and cumbersome operation, making it difficult to quickly adapt to diverse exhaust pipe specifications. This leads to prolonged preparation time and reduced testing efficiency. Second, poor stability. Some fixtures use rigid clamping methods, lacking anti-slip and cushioning structures. During testing, they are prone to loosening and displacement due to vehicle vibrations, smooth exhaust pipe surfaces, etc., which not only compromises the airtightness of the testing environment, causing exhaust gas processor leaks and distorting test data, but also poses safety hazards due to fixture detachment. Third, insufficient adjustment flexibility. The front-to-back position and angle adjustment of traditional fixtures largely rely on manual operation, resulting in low precision and difficulty in ensuring accurate alignment between the testing head and the exhaust pipe, further affecting the reliability of test results. Fourth, an imbalance between portability and versatility. Some highly adaptable fixtures are complex in structure and bulky in size, making them inconvenient to move and deploy on site. On the other hand, miniaturized fixtures have problems such as insufficient clamping force and narrow adaptability, which cannot meet the usage needs of different testing scenarios (such as fixed testing at testing stations and mobile sampling inspections).

[0003] A fixing device for an on-board exhaust gas processor testing device, with publication number CN220926168U, relates to the field of vehicle testing. In this fixing device, a clamp for fixing a flow meter is fixedly installed on the bottom platform, and a support base is provided at the bottom of the bottom platform. The upper and lower ends of a first telescopic component are rotatably connected to a top platform and a middle platform component, respectively, and are vertically retractable. The middle platform component is used to house the main unit and power supply of the on-board exhaust gas processor testing device, and the top platform is located above the middle platform component. The upper and lower ends of a second telescopic component are rotatably connected to the middle platform component and the bottom platform, respectively, and are vertically retractable. The flow meter of the on-board exhaust gas processor testing device can be fixed to the clamp on the bottom platform, and the main unit, power supply, etc., can be fixed on the middle platform component. All modules of the on-board exhaust gas processor testing device can be uniformly placed on this fixing device to prevent haphazard placement.

[0004] Although the aforementioned mounting device for vehicle exhaust gas processor detection equipment has an arc-shaped clamp and an anti-slip layer, the exhaust pipes of different vehicle models vary greatly in size and shape, which may not be fully compatible with all vehicle models, resulting in insecure or non-secure mounting.

[0005] Therefore, a fixture fixing device for exhaust gas processor detection is proposed to address the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The following describes an embodiment of this utility model based on its overall structure.

[0030] like Figures 1 to 4 As shown, this utility model provides a gas processor detection fixture fixing device, including an adjusting block 21. An adjusting column 13 is fixedly provided on the front end face of the adjusting block 21, a limiting plate 11 is fixedly provided on the upper end face of the adjusting block 21, an arc-shaped clamping plate 14 is fixedly provided on the front end face of the adjusting block 21, an anti-slip layer 15 is fixedly provided inside the arc-shaped clamping plate 14, and limiting blocks 12 are fixedly provided on both the left and right sides of the adjusting block 21. The arc-shaped clamping plate 14 can be used to clamp the gas processor emission component. The anti-slip layer 15 can increase the friction and prevent the component from sliding during the clamping process, thereby improving the stability and reliability of the device. The limiting plate 11 and the limiting block 12 help to position and limit the adjusting block 21 in subsequent operations, ensuring the normal operation of the device.

[0031] In this embodiment, the front end face of the adjustment block 21 is fixedly provided with an adjustment ring 18, the inside of the adjustment ring 18 is provided with an adjustment groove 19, and the adjustment groove 19 is slidably arranged with the adjustment column 13. The front end face of the adjustment ring 18 is fixedly provided with an electric rotating shaft 20. Through the adjustment ring 18 and the adjustment column 13, the position of the adjustment block 21 can be adjusted within a certain range to adapt to different exhaust gas processor detection requirements.

[0032] A fixing block 17 is fixedly provided on the outer side of the limiting block 12. A limiting groove 16 is opened inside the fixing block 17, and the limiting groove 16 is slidably arranged with the limiting block 12. Through the fixing block 17 and the limiting groove 16, the left and right movement of the adjusting block 21 is further restricted, preventing the adjusting block 21 from shaking or shifting during operation, thus ensuring the stability of the device and the accuracy of the test results.

[0033] A connecting ring 10 is fixedly provided on the rear end face of the adjusting block 21, and a fixing tube 6 is fixedly provided on the rear end face of the connecting ring 10. An electric telescopic rod 8 is fixedly provided inside the fixing tube 6, and a detection head 9 is fixedly provided on the front end face of the electric telescopic rod 8. Through the electric telescopic rod 8, the detection head 9 can be extended and retracted within a certain range, which can adapt to the detection needs of exhaust gas processors at different positions and depths, and improve the flexibility and applicability of the detection.

[0034] The rear end face of the fixed tube 6 is fixedly provided with a detection device 3, and the front end face of the fixed tube 6 is fixedly provided with a protective cover 7. The adjusting block 21 is inside the protective cover 7. The protective cover 7 can prevent the adjusting block 21 and the detection head 9 from being affected by the external environment, such as dust and water vapor, thus extending the service life of the device and ensuring the accuracy of the detection results.

[0035] The detection device 3 is equipped with sliders 5 on both the left and right sides. An electric slide rail 4 is fixed on the left end face of the slider 5. The detection device 3 can move horizontally through the electric slide rail 4 and the slider 5, which facilitates the detection of exhaust gas processors at different locations and improves the detection efficiency.

[0036] The lower end face of the detection device 3 is fixedly provided with a base plate 1, and the electric slide rail 4 is fixedly provided with the base plate 1. The lower end face of the base plate 1 is fixedly provided with a caster wheel 2. Through the caster wheel 2, the entire exhaust gas processor detection fixture fixing device can be easily moved to different detection locations, which improves the flexibility and applicability of the device.

[0037] Working principle and process of a gas processor detection fixture fixing device:

[0038] The device is mounted on a base plate 1 with casters 2, allowing it to be moved flexibly to the vicinity of the vehicle requiring exhaust gas processor testing. The operator pushes the device, using the casters 2 to move it to the appropriate testing position. An electric slide rail 4 fixed on the base plate 1 engages with sliders 5 on both sides of the testing device 3, controlling the horizontal position of the device. The operator operates the electric slide rail 4, causing the sliders 5 to slide along it, thus moving the testing device 3 to approximately the location of the vehicle's exhaust gas processor outlet. The front end of the testing device 3 is connected to a connecting ring 10 and an adjusting block 21 via a fixed tube 6. An electric telescopic rod 8 inside the fixed tube 6 can extend and retract. When the electric telescopic rod 8 extends forward, it pushes the adjusting block 21 closer to the vehicle's exhaust gas processor outlet. The adjusting post 13 on the front face of the adjusting block 21 slides into the adjusting groove 19 inside the adjusting ring 18. Simultaneously, the electric rotating shaft 20 drives the adjusting ring 18 to rotate, thereby adjusting the angle of the adjusting block 21 so that the arc-shaped clamp 14 can accurately align with the exhaust gas processor outlet. The left and right sides of the adjusting block 21... The limiting block 12 and the limiting groove 16 in the fixing block 17 are slidably set, which ensures the stability of the adjusting block 21 during movement. When the adjusting block 21 reaches the appropriate position, the arc-shaped clamp 14 clamps the exhaust port of the vehicle exhaust processor. The anti-slip layer 15 inside the arc-shaped clamp 14 increases the friction with the exhaust port of the exhaust processor, ensuring a firm clamping and preventing the device from loosening during the testing process. After the arc-shaped clamp 14 clamps the exhaust port of the exhaust processor, the detection head 9 enters the exhaust port of the exhaust processor under the push of the electric telescopic rod 8. The detection head 9 is connected to the detection device 3 via a fixed pipe 6. After collecting the exhaust gas processor sample, the detection head 9 transmits the data to the detection device 3 for analysis and processing, thereby obtaining the detection results such as the content of various components in the exhaust gas processor. When the exhaust gas processor detection is completed, the electric telescopic rod 8 retracts, driving the detection head 9 to exit from the exhaust gas processor outlet. The electric slide rail 4 controls the detection device 3 to return to the initial position. The adjusting block 21 also returns to its original position with the cooperation of the electric telescopic rod 8, the adjusting column 13, the adjusting ring 18, and other components, preparing for the next detection.
