Its upper part is fixedly connected to the steering wheel, and its lower part is connected to the steering gear. After the steering shaft is manufactured, its shape needs to be inspected. The cross-sectional size of the steering shaft perpendicular to the central axis varies, which increases the difficulty of inspecting its shape on the production line. In the past, manual handheld inspection devices were used for inspection, which was inefficient and prone to misjudgment. It was also easy to cause bumps and affect performance. Therefore, it is necessary to design an automatic inspection device for car steering shafts. Summary of the Invention
