AI Technical Summary
In the existing technology, the flatness detection of gearbox nuts relies on manual inspection, which leads to inaccurate measurement and low efficiency.
Design a device for detecting the flatness of a gearbox nut, including a base plate. The detection device on the base plate automatically transfers the workpiece by driving a slide plate with a cylinder. A product positioning seat accurately positions the workpiece. A displacement sensor accurately measures the flatness of the workpiece. An air blowing pipe promptly removes impurities. A buffer reduces mechanical vibration interference. The cooperation between the slide rail and the slide plate ensures smooth movement.
The system enables automated inspection of gearbox nuts, improving inspection accuracy and efficiency, ensuring consistency and stability of inspection positions, and avoiding the impact of impurities on inspection accuracy.
