Description
Technical Field
[0001] The invention relates to the technical field of vehicle dynamic balance testing, in particular to a vehicle rotating component dynamic balance testing device. Background Art
[0002] During the manufacturing and assembly process of vehicles, some rotating components may have hidden defects and assembly flaws due to multiple factors such as component material properties, processing accuracy and assembly errors. These problems can easily cause mechanical fatigue, thereby reducing the service life of components and increasing the probability of accidents. In view of this, in order to ensure that rotating components have high reliability, dynamic balancing tests must be performed before they are assembled or put into use to ensure the reliability of the rotating components.
[0003] Existing dynamic balancing test equipment is generally highly specialized and has relatively strict requirements or restrictions on the size of the test object, making it difficult to flexibly adapt to rotating components of various sizes.
[0004] In order to solve the above technical problems, in the prior art, a Chinese patent with publication number CN218381421U discloses a dynamic balancing test device, which can realize the limited tensioning of the belt by means of a fixed roller and an adjusting roller. Since the circumference of the belt is fixed, when testing a rotating body of different radial sizes, the belt tightness can be adjusted by adjusting the spacing between the two adjusting rollers, so that the belt always maintains a suitable tightness, thereby ensuring the transmission effect of the belt. The position adjustment is realized by sliding the support, the driving seat and the sliding seat on the slide rail, and when fixed rollers are required, the belt is adjusted to the desired position. Regularly tighten the fixing bolts to increase the friction between the fixing bolts and the base to fix the support, drive seat and sliding seat. At the same time, the mechanical structure is used for fixing. The fixed support, drive seat and sliding seat are not easy to slide. The vibration data and rotation speed of the rotating body can be measured respectively by vibration sensors and photoelectric sensors. The dynamic balancing accuracy of the rotating body can be analyzed using the measured data. At the same time, the distance between the two supports is adjustable to adapt to rotating bodies of different lengths. The height of the limiting roller is adjustable to adapt to mandrels of different radial sizes and to test rotating bodies of different sizes.
[0005] Moreover, in the prior art, a Chinese patent with publication number CN216899426U discloses a tire dynamic balance test device, including a frame, a rotating shaft, a base, a lifting assembly and an adjusting assembly, wherein the base is fixedly mounted on the bottom of the frame, a guide rail is arranged on the side of the base, the guide rail is slidably connected to the movable frame, and the position of the movable frame on the guide rail is changed by a built-in driving unit; the lifting assembly is rotatably mounted on the movable frame, and one end is driven to rotate by an external motor; the adjusting assembly is arranged at the execution end of the lifting assembly to fix the position of the tire; it is convenient to replace during use, and it is convenient to place the tire on the rotating shaft, which can reduce the frequency of workers' participation in the test process and effectively improve the efficiency of the test.
[0006] During use, the above-mentioned device utilizes the driving seat and the sliding seat to clamp the components, thereby facilitating the detection of the components. However, the driving seat and the sliding seat only clamp the components, and the clamping mechanism is easily affected by the rotational force and causes shaking, and the clamping components are easily damaged due to long-term rotation, which is not conducive to maintenance by personnel. Therefore, in actual use, the clamping mechanism may shake, resulting in inaccurate detection and easy damage, making maintenance difficult. Summary of the invention
