Document Type and Number:
WIPO Patent Application WO/2022/111057
Kind Code:
A1
Abstract:
An air tightness testing device for a wheel hub, the air tightness testing device comprising a testing machine (1), a telescopic arm (2), a water tank (3), an electric motor (4), a wheel hub (5) and a clamp (6), wherein a weight sensing device (7) is arranged at the bottom of the water tank (3), and the weight sensing device (7) is used for measuring the volume of water in the water tank (3); a first alarm device (8) is arranged on an outer surface of the water tank (3), and the first alarm device (8) is connected to the weight sensing device (7); liquid sensing devices (9) are arranged on the clamp (6), and the liquid sensing devices (9) are used for detecting whether the clamp (6) comes into contact with the water; and a second alarm device (10) is arranged on the testing machine (1), and the second alarm device (10) is connected to the liquid sensing device (9). The weight sensing device (7) is arranged below the water tank (3) and connected to the first alarm device (8), and the liquid sensing devices (9) are arranged on the upper and lower end faces of the clamp (6) to detect whether the wheel hub (5) is completely submerged in water, such that the device has a simple overall structure, the working efficiency of testing the air tightness of the wheel hub (5) is improved, and incomplete immersion of the wheel hub (5) due to insufficient water in the water tank (3) is avoided.
