AI Technical Summary
In the prior art, structural damage or specimen breakage may occur during the dynamic balancing test of the crankshaft at high speed, resulting in high-speed flying fragments that pose a potential risk of personal injury to the operator.
An auxiliary tooling for crankshaft dynamic balancing testing was designed, including a protective device and a cleaning device. The protective device is connected to the crankshaft through a protective cover to form a sealed space to prevent debris from splashing. The cleaning device automatically cleans debris through a slide rod and push plate structure to avoid debris accumulation.
It effectively blocks debris from flying during the detection process, ensuring operational safety, and improves cleaning efficiency and maintenance convenience, thereby enhancing the overall safety and visibility of the operation.
