Description

Technical Field

[0001] The utility model relates to a pressure resistance testing machine, in particular to a pressure resistance testing machine for a universal joint dust cover, and belongs to the technical field of universal joints. Background Art

[0002] Universal joints are mechanical parts that realize variable-angle power transmission. They are used in positions where the direction of the transmission axis needs to be changed. They are the "joint" parts of the universal transmission device of the automobile drive system. The combination of the universal joint and the transmission shaft is called a universal joint transmission device. In front-engine rear-wheel drive vehicles, the universal joint transmission device is installed between the transmission output shaft and the input shaft of the drive axle final reducer; while front-engine front-wheel drive vehicles omit the transmission shaft, and the universal joint is installed between the front axle half shaft and the wheel, which is responsible for both driving and steering.

[0003] Dust covers are required when using universal joints. During the production process of the dust covers, they need to be pressure tested to test their specific pressure resistance values. Existing pressure resistance testing machines lack protective measures during use. If the pressure resistance of the produced dust covers is unqualified, they may be damaged due to the pressure caused by the pressure head. When the dust covers are damaged, debris may fly. On the one hand, the debris may fly onto the workers and cause injuries to them, posing a safety hazard. On the other hand, it may accumulate at the testing machine, affecting the next pressure resistance test. The workers are required to clean them up, affecting the test efficiency.

[0004] Therefore, a pressure resistance testing machine for a universal joint dust cover is proposed. Utility Model Content
