This invention provides a self-limiting conveying device for processing automotive flywheels, comprising a base plate, a wheel, a push block, a positioning block, a positioning mechanism, an output component, and an input component. The operator places the flywheel to be processed on the input component. Driven by a belt, the flywheel enters the channel. The operator rotates the rocker counterclockwise, causing the wheel to rotate, which in turn causes the push block to propel the flywheel forward to the processing station and then back. During the return process, the positioning block swings and positions the flywheel at the processing station. At this point, the flywheel is in a fixed state, and the processing equipment begins operation. After processing is completed, the operator continues to rotate the rocker, causing the positioning block to retract, and the flywheel to be in a free state. The push block then propels newly arrived unprocessed flywheels forward and pushes out the processed flywheel. The pushed-out flywheel enters the output component and is transported to the next station. This device solves the problem of low work efficiency in traditional flywheel processing where the operator must both move and position the flywheel.
