Design and fabrication of automatic tilt angle adjustment device for precision measurement application

This article describes the design and fabrication of an angle tilt adjustment device that automatically adjusts the measured surface to parallel the surface plate. The device features a 150 mm 150 mm worktable and enables independent tilt adjustment of the worktable surface in the X and Y directions via two worm-gear pairs driven by stepper motors. For high angular resolution around the OX and OY axes, the device employs a transmission ratio of 6781 from two motors to these axes. The experimental results reveal that the adjusted average nonparallelism between the measured surface and the surface plate reaches 0.001 mm. The results indicate that the device is fully capable of performing accurate measurements. The device is compact, easy to carry, and low in production cost, making it ideal for installation in small and medium mechanical workshops.
