Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub detection, in particular to a wheel hub fixing device for aluminum alloy wheel hub dynamic balance detection equipment. Background Art

[0002] Tire dynamic balancing is essential to enhance driving safety. When the wheels are unbalanced during high-speed driving, it may cause the vehicle to shake, and in severe cases even lose control, increasing the risk of accidents. Dynamic balancing can eliminate wheel imbalance and ensure that the wheels are in a stable state when rotating at high speeds, thereby keeping the car running normally and reducing the risk of accidents caused by unstable driving.

[0003] During the wheel production process, all wheels entering the warehouse need to be dynamically balanced to ensure the safety and stability of the installed vehicles. This results in the need for wheel manufacturers to frequently replace new tires that need to be tested on the dynamic balancing machine. The existing dynamic balancing machine has no auxiliary lifting equipment and needs to be manually carried and installed, which is very physically demanding. The position of the limit mechanism of the existing dynamic balancing detection machine is fixed. For manufacturers with production needs of various sizes, especially special-sized wheels, the fixed-position limit mechanism may cause the installed wheel to be too close to the equipment, posing certain safety hazards, or the distance between the wheel and the equipment is too far, affecting stability. Therefore, the dynamic balancing machine needs to keep a relatively appropriate distance between the wheel and the dynamic balancing machine after the wheel is installed. Utility Model Content

[0024] Specifically, the lifting mechanism 2 includes a lifting frame 21, an electric telescopic rod 22, a lifting block 23, a telescopic rod 24 and a supporting block 25. The lifting frame 21 is installed on the outside of the dynamic balancing machine 1, the electric telescopic rod 22 is installed on both sides of the lifting frame 21, the lifting block 23 is clamped on the inside of the lifting frame 21, the telescopic rod 24 is fixedly arranged on the outside of the lifting block 23, the supporting block 25 is movably connected to the end of the telescopic rod 24, the two ends of the lifting block 23 pass through and extend to the outside of one side of the lifting frame 21, and the telescopic end of the electric telescopic rod 22 is fixedly connected to the top of the lifting block 23.

The bottom of the locking screw inside the limit plate 4 is in close contact with the bottom of the groove on the surface of the output shaft 3.

[0025] In this embodiment, the mounting assembly 5 is first adjusted according to the hub size to be detected to ensure that the inner side of the installed hub maintains an appropriate distance from the dynamic balancing machine 1 to ensure stable rotation of the hub. The locking screws at the top and bottom of the limit plate 4 can be loosened to adjust the position of the limit plate 4 on the surface of the output shaft 3.
