AI Technical Summary
In existing thread inspection processes, threaded workpieces are prone to slight displacement or circumferential rotation, causing the images captured by the camera to deviate from the inspection area, resulting in insufficient stability and affecting the accuracy of the inspection data.
A vision-based thread inspection device is adopted, including a base plate, inspection components, lateral adjustment components, longitudinal adjustment components, and clamping components. Through the cooperation of the thread rod and thread block driven by the motor, the threaded workpiece is accurately aligned and firmly clamped, avoiding displacement and rotation.
Stable detection of threaded workpieces has been achieved, improving the clarity and accuracy of the detection images and ensuring the reliability of the detection data.
