[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 , Figure 4 , Figure 5 An embodiment of this utility model provides a stabilizer bar noise testing machine, including an operating table 1. The upper side of the operating table 1 has movable grooves 16 on both the left and right sides. Electric push rods 28 are fixedly connected to the inner walls of the movable grooves 16 on adjacent sides. A support plate 17 is fixedly connected to the output end of the electric push rods 28. A fixing frame 18 is fixedly connected to the upper part of the support plate 17. Fixing plates 20 are fixedly connected to the upper and lower sides of the fixing frame 18 on adjacent sides. Bolts 21 are threaded inside the upper fixing plate 20. An upper arc plate 22 is threaded to the lower side of the bolts 21. A lower arc plate 23 is fixedly connected to the upper part of the lower fixing plate 20. Extension plates 24 are fixedly connected to both sides of the openings of the upper and lower arc plates 22 and 23. A fixing assembly is fixedly connected to the bottom of the upper extension plate 24. The fixing assembly is used to fix the upper arc plate 22 and lower arc plate 23, thereby fixing the stabilizer bar and ensuring stability during testing. An installation groove 27 is provided inside the lower extension plate 24.

[0032] The fixing component includes an elastic clip 25, which is fixedly connected to both sides of the bottom of the upper extension plate 24. A push block 26 is fixedly connected to the bottom of the elastic clip 25. The elastic clip 25 and the push block 26 are slidably connected inside the mounting groove 27. The upper side of the protruding end of the elastic clip 25 is attached to the bottom of the lower extension plate 24. The support plate 17 is slidably connected inside the moving groove 16 to fix the stabilizer rod. The fixing frame 18 has a through groove 29 inside. The rod 19 is slidably connected inside the through groove 29 and is engaged inside the upper arc plate 22 and the lower arc plate 23.

[0033] By activating the electric actuator 28, the support plate 17 is slid within the moving slot 16, adjusting it to a suitable position for the stabilizer bar to be tested. Then, the stabilizer bar body 19 is inserted into the lower arc plate 23 via the through slot 29. Rotating the bolt 21 causes the upper arc plate 22 to move downwards. During this downward movement, the push block 26 is simultaneously pinched and pulled inwards, smoothly inserting the elastic clip 25 into the mounting slot 27. This ensures a tight fit between the upper and lower arc plates 22 and 23. Once the upper and lower arc plates 22 are fully engaged, the elastic clip 25 is no longer compressed and returns to its original position using its own rebound force, hooking the lower arc plate 23 and ensuring a secure fixation of the upper and lower arc plates 22 and 23. This achieves reliable clamping of the stabilizer bar, improves testing efficiency and accuracy, and provides a reliable guarantee for the quality inspection of the stabilizer bar.

[0034] Reference Figure 1 , Figure 2 , Figure 3 A support frame 2 is fixedly connected to the upper part of the operating table 1. A slide groove 3 is opened inside the upper side of the support frame 2. An electric push rod 4 is fixedly connected to one side of the inner wall of the slide groove 3. A sliding frame 5 is fixedly connected to the output end of the electric push rod 4. A connecting plate 6 is fixedly connected to the bottom of the sliding frame 5, so that it drives the pulling mechanism to detect the various positions of the stabilizer rod. A motor 7 is fixedly connected to one side of the connecting plate 6. A rotating shaft 8 is fixedly connected to the output end of the motor 7. An eccentric wheel 9 is fixedly connected to the outside of the rotating shaft 8. A connecting rod 1 is fixedly connected to one side of the inside of the eccentric wheel 9. 0. A connecting ring 12 is rotatably connected to the outside of the connecting rod 10. A pulling rod 13 is fixedly connected to the bottom of the connecting ring 12. A fixing ring 14 is rotatably connected to the bottom of the pulling rod 13. A fixing ring 15 is installed at the bottom of the fixing ring 14. A rod body 19 is engaged inside the fixing ring 15 to detect noise on the stabilizing rod. One side of the connecting rod 10 is threaded. A nut 11 is threaded on the outside of one side of the connecting rod 10 to fix the position of the pulling rod 13 and prevent it from falling off. The sliding frame 5 is slidably connected inside the slide groove 3.

[0035] By starting motor 7, the rotating shaft 8 is driven to rotate, which in turn drives eccentric wheel 9 to rotate. The rotation of eccentric wheel 9 transmits motion through connecting rod 10. Connecting rod 10 rotates inside connecting ring 12, ensuring the smoothness and accuracy of the movement. The rotation of connecting rod 10 pulls pulling rod 13, which, driven by fixed ring 14 and fixed ring 15, pulls the stabilizer bar. At the same time, electric actuator 4 is activated, which pushes sliding frame 5 to slide inside slide groove 3. The sliding of sliding frame 5 drives the pulling mechanism through connecting plate 6, causing fixed ring 14 and fixed ring 15 to slide along the outside of the stabilizer bar. This comprehensive inspection of all positions of the stabilizer bar ensures that no key point is missed. Throughout the process, the stabilizer bar is pulled at different positions to detect whether it generates noise. This not only allows for comprehensive inspection of all positions of the stabilizer bar but also simulates the stress conditions in actual use, ensuring the accuracy and reliability of the test results and providing strong support for the quality control of the stabilizer bar.

[0036] Working principle: When the device is needed, the electric push rod 28 is activated to push the support plate 17 and slide it inside the moving groove 16. Adjust it to a suitable position with the stabilizer bar to be tested. Then, the rod body 19 is inserted into the lower arc plate 23 through the through groove 29. The bolt 21 is rotated to move the upper arc plate 22 downward. At the same time, the push block 26 is pinched and brought inward. As the upper arc plate 22 moves downward, the elastic clip 25 is smoothly inserted into the mounting groove 27. When the upper arc plate 22 and the lower arc plate 23 are in contact, the elastic clip 25 is no longer squeezed. It returns to its original position by its own rebound force and hooks the lower arc plate 23. The upper arc plate 22 and the lower arc plate 23 are fixed to clamp and fix the stabilizer bar. This ensures that the stabilizer bar is firmly clamped, guaranteeing the stability and reliability of the clamping. It is suitable for stabilizer bar testing and fixing needs in various occasions.

[0037] By starting the motor 7, the shaft 8 is driven, causing the eccentric wheel 9 to rotate and drive the connecting rod 10, which rotates inside the connecting ring 12. This causes the pulling rod 13 to be pulled, and the stabilizer bar is pulled by the fixed ring 14 and the fixed ring 15. At the same time, the electric push rod 4 can be started, pushing the sliding frame 5 to slide inside the slide groove 3. This, through the connecting plate 6, drives the pulling mechanism, causing the fixed ring 14 and the fixed ring 15 to slide outside the stabilizer bar. This allows for the detection of noise at various positions of the stabilizer bar. This not only enables comprehensive detection of various positions of the stabilizer bar but also simulates the stress conditions in actual use, ensuring the accuracy and reliability of the test results.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
