AI Technical Summary
Traditional line marking instrument accuracy testing relies on outsourcing services, resulting in a complex testing process, long cycle, high cost, waste of human resources, and inability to continuously monitor, which affects production efficiency and increases enterprise operating costs.
Design a testing device for the guide rail of a scribing instrument, including straightness and parallelism testing components. It uses an autocollimator and reflector for automated data acquisition, and combines leveling components and support platform to adapt to different mounting surfaces. It generates a guide rail accuracy report and provides accurate testing basis.
It improves detection efficiency and accuracy, shortens detection time, reduces manual reading errors, lowers tooling costs for enterprises, and achieves efficient and reliable detection of guide rail accuracy.
