AI Technical Summary

Technical Problem

The existing roller turret cam indexing device faces challenges in achieving high precision positioning of the rotating component due to rotational friction torque and other factors hindering the motor's response, resulting in inaccurate angular positioning.

Method used

A rotating device incorporating a micro-motion mechanism and a coarse motion mechanism, with a fine adjustment mechanism providing higher angular resolution, allows for precise positioning by combining these mechanisms to achieve a wide angle range and high precision.

Benefits of technology

The device enables accurate positioning of the rotating component to a target angular position with a precision of less than 1 arcsecond, overcoming the limitations of previous technologies by using a multi-layered motion control system.

Abstract

A rotating device 100 is provided that can position a rotating member 102 to a target angular position with high precision. The rotating device 100 includes: a fine adjustment mechanism 109 having a base member 110; and a coarse adjustment mechanism 101 having a housing 104 and at least a portion of the rotating member 102 housed within the housing 104 and disposed on the base member 110. The rotating member 102 is rotatable relative to the housing 104 about a rotating member axis 103, and the coarse adjustment mechanism 101 as a whole is rotatable relative to the base member 110 about a rotating member axis 103.
